Summary

TLDRThe video script discusses the fundamental concepts of demand and supply within the field of economics. It explains how the interaction between buyers and sellers leads to an imbalance in the quantity demanded and supplied, which in turn affects prices and can cause scarcity. The presenter uses examples such as the increase in the price of basic necessities before a holiday like Idul Fitri and the high cost of clean water in certain areas to illustrate these points. The script also delves into the law of demand, which states that as prices rise, the quantity demanded falls, and the law of supply, which operates in the opposite direction. Mathematical representations are provided to help understand these concepts, with the demand curve depicted as downward-sloping and the supply curve as upward-sloping. The video aims to educate viewers on these economic principles and prepare them for further discussions on the topic.

Takeaways

  • 📈 The concept of supply and demand is fundamental in economics, explaining how the balance between the quantity of goods and services that producers are willing to sell and the quantity that consumers are willing to buy influences prices.
  • 🛒 Demand refers to the quantity of a product that consumers are willing and able to purchase at various prices, with the law of demand stating that as the price of a product increases, the quantity demanded typically falls, and vice versa.
  • 📦 Supply refers to the quantity of a product that producers are willing to sell at various prices, with the law of supply stating that as the price of a product increases, the quantity supplied typically increases, and vice versa.
  • 💰 The goal of producers is not just to sell products but to maximize profit, which is the difference between the cost of production and the revenue received from sales.
  • 🌐 The interaction between buyers and sellers in a market economy is a circular flow where demand and supply meet, leading to the determination of market prices.
  • ⏫ The demand curve is downward-sloping, indicating that higher prices generally lead to a decrease in the quantity demanded, reflecting consumers' preference for lower prices and their budget constraints.
  • ⏬ The supply curve is upward-sloping, showing that higher prices encourage producers to supply more of a product, as they aim to increase profits.
  • 🔄 Both demand and supply curves can shift due to various factors such as changes in consumer preferences, technological advancements, or government policies.
  • 📊 A demand schedule is a table that shows the relationship between the price of a good and the quantity demanded at that price, which can be graphically represented as a demand curve.
  • 📈 An increase in price typically results in a movement along the demand curve, reflecting the decrease in quantity demanded, while a shift in the demand curve itself can occur due to external factors affecting the desire to purchase the product.
  • 📉 Similarly, an increase in price can lead to a movement along the supply curve, with producers supplying more at a higher price, but external factors can also cause the supply curve to shift, affecting the quantity supplied at each price level.

Q & A

  • What are the main concepts discussed in the script?

    -The script discusses the concepts of demand and supply in economics, explaining what they mean and how they interact to affect market prices.

  • Why do prices of basic needs increase around holidays like Idul Fitri?

    -The increase in prices around holidays like Idul Fitri is due to an imbalance between demand and supply. The demand for basic needs is high during this time, and if supply cannot meet this demand, prices will rise.

  • What is the law of demand in economics?

    -The law of demand states that as the price of a good or service increases, the quantity demanded decreases, and vice versa. This is because consumers tend to buy less of a product when it becomes more expensive.

  • How does scarcity affect the market?

    -Scarcity occurs when the quantity of goods available is limited while the demand is high. It can lead to an increase in prices and potentially create a shortage of the product in the market.

  • What is the difference between demand and supply from the perspective of consumers and producers?

    -Demand is from the consumer's perspective, where they want to obtain satisfaction or utility from a product. Supply, on the other hand, is from the producer's perspective, where they aim to offer goods or services with the goal of making a profit.

  • What is the relationship between the price of a product and the quantity supplied according to the law of supply?

    -According to the law of supply, there is a direct relationship between the price of a product and the quantity supplied. As the price increases, the quantity supplied also increases, and vice versa, because producers are motivated to produce and sell more when they can charge higher prices.

  • Why do producers increase the quantity they offer when prices rise?

    -Producers increase the quantity they offer when prices rise because higher prices can lead to higher profits. They aim to maximize their earnings, so they are willing to supply more goods at higher prices.

  • What is the shape of the demand curve and what does it represent?

    -The demand curve is downward-sloping, which means it moves from the upper left (high prices, low quantity demanded) to the lower right (low prices, high quantity demanded). This represents the negative relationship between price and quantity demanded.

  • How does the script explain the mathematical representation of the demand curve?

    -The script explains that the demand curve has a negative slope mathematically by showing that when the price (P) increases, the change in quantity demanded (ΔQd) decreases, resulting in a negative value when the change in price (ΔP) is divided by the change in quantity demanded.

  • What factors can cause the demand and supply curves to shift?

    -The script does not explicitly list the factors, but common factors that can cause shifts in demand and supply curves include changes in consumer preferences, income levels, production costs, technological advancements, and government policies.

  • What is the purpose of understanding the demand and supply schedule and curves in economics?

    -Understanding the demand and supply schedule and curves helps economists and individuals to analyze and interpret market behavior, predict price changes, and make informed decisions about production and consumption.

📈 Introduction to Demand and Supply Concepts

The first paragraph introduces the fundamental concepts of demand and supply in economics. It explains the interaction between consumers and sellers, and how the balance between the quantity demanded and supplied affects prices. The example of increased prices for basic needs before a holiday, such as Idul Fitri, is used to illustrate the imbalance that can lead to price hikes and scarcity. The paragraph also touches on the unlimited nature of human needs and wants, which is a key driver of economic activity.

05:01

📉 The Law of Demand and Its Impact on Consumers

This paragraph delves into the law of demand, which states that as the price of a product increases, the quantity demanded decreases, and vice versa. It discusses how consumers look for quality products at lower prices, using the example of a handphone. The concept of diminishing demand as prices rise is explored, highlighting the consumer's desire to maximize utility while minimizing expenditure. The paragraph also mentions the influence of price changes on the quantity demanded, both in a theoretical and practical sense.

10:04

📚 Understanding the Supply Schedule and Its Graphical Representation

The third paragraph focuses on the supply schedule, which is a table showing the quantity of goods offered at various prices. It illustrates this with an example where the quantity supplied increases as the price increases. The paragraph then explains how this information is translated into a supply curve, which typically has a positive slope, indicating a direct relationship between price and quantity supplied. The mathematical representation of the supply curve is also discussed, emphasizing the upward movement from the bottom left to the top right.

15:05

🔄 Shifts in Demand and Supply Curves

The final paragraph addresses the factors that can cause demand and supply curves to shift. It emphasizes the dynamic nature of these economic models and hints at the upcoming discussion on the reasons behind the shifts of these curves. The paragraph also provides a brief overview of the mathematical approach to understanding shifts in the demand and supply curves, suggesting that changes in price and quantity result in a positive or negative slope, depending on the direction of the change.

Keywords

💡Demand

Demand refers to the quantity of a product or service that consumers are willing and able to purchase at various prices during a given period. In the video's context, it is tied to the economic concept where an increase in price typically leads to a decrease in demand, as consumers may seek alternatives or reduce their consumption. The script mentions 'permintaan' which is 'demand' in Indonesian, and explains how it decreases when prices rise, as seen in the example of increased prices during Idul Fitri.

💡Supply

Supply is the total amount of a specific product or service that is available to consumers. It is influenced by factors such as production costs and market conditions. The video discusses 'penawaran' or 'supply' in Indonesian, highlighting the relationship between price and the quantity supplied, where higher prices encourage producers to supply more.

💡Economic Imbalance

Economic imbalance occurs when there is a discrepancy between supply and demand. The script uses the example of essential goods' prices soaring before Idul Fitri due to an imbalance, where demand exceeds supply, leading to higher prices and potential scarcity.

💡Scarcity

Scarcity is an economic concept that refers to the state where the demand for goods and services exceeds their availability. The video script mentions 'kelangkaan' which means scarcity, explaining that it can occur when the demand is high, but the supply is limited, as in the case of clean water in certain areas.

💡Price Elasticity of Demand

Price elasticity of demand measures the responsiveness of the quantity demanded of a good to a change in its price. The script explains that if the price increases, the demand decreases, which is a fundamental law of demand and is exemplified by consumers seeking cheaper alternatives.

💡Consumer

A consumer is an individual who purchases goods and services for personal use. The video script discusses consumers in the context of 'konsumen' in Indonesian, emphasizing that they not only buy products but also use them to derive satisfaction or utility.

💡Producer

A producer is an individual or company that creates or supplies goods or services to the market. The script refers to 'produsen' or producers in Indonesian, noting that their goal is not just to sell products but to maximize profit.

💡Profit Maximization

Profit maximization is the primary goal of producers, where they aim to earn the highest possible profit from their business operations. The video script mentions this concept when discussing why producers increase the supply of goods when prices rise.

💡Demand Schedule

A demand schedule is a table that shows the relationship between the price of a product and the quantity demanded at each price level. The script provides an example of a demand schedule with different prices and the corresponding quantities demanded.

💡Demand Curve

A demand curve is a graphical representation of the demand schedule, illustrating the inverse relationship between price and quantity demanded. The script describes the demand curve as downward-sloping, indicating that as price increases, the quantity demanded decreases.

💡Supply Schedule

A supply schedule is a table that shows the relationship between the price of a product and the quantity supplied at each price level. The script discusses a supply schedule, indicating how the quantity supplied increases as the price increases.

💡Supply Curve

A supply curve is a graphical representation of the supply schedule, showing the direct relationship between price and quantity supplied. The script explains that the supply curve has a positive slope, meaning that as price increases, the quantity supplied also increases.

Highlights

The concept of demand and supply is crucial in economics, influencing the price levels and scarcity of goods.

An imbalance between the quantity of demand and supply can lead to price volatility and scarcity.

Human needs and wants are unlimited, which can lead to increased demand for limited resources.

The interaction between buyers and sellers is central to the occurrence of demand and supply.

Demand is not just about purchasing but also about consuming the utility value of a product.

The purpose of a producer is not only to sell products but to make a profit.

The law of demand states that as the price increases, the quantity demanded decreases, and vice versa.

Consumers prefer quality goods at a lower price, which is reflected in the demand curve.

The law of supply states that as the price increases, the quantity supplied also increases, and vice versa.

Producers aim to maximize profit by selling goods at higher prices when demand is high.

The demand curve is downward-sloping, indicating a negative correlation between price and quantity demanded.

The supply curve is upward-sloping, showing a positive correlation between price and quantity supplied.

The demand and supply curves can shift due to various factors, such as changes in consumer preferences or production costs.

The demand schedule is a table that shows the quantity demanded at different price levels.

The supply schedule is a table that shows the quantity supplied at different price levels.

Shifts in the demand and supply curves can be mathematically represented and analyzed.

Understanding the shifts in demand and supply curves is essential for interpreting market changes and predicting price movements.

Factors such as government policies, technological advancements, and consumer tastes can cause the curves to shift.

hai hai halo halo teman-teman kali ini

play00:03

kita akan membahas salah satu konsep

play00:05

penting dalam ilmu ekonomi yaitu

play00:07

permintaan dan penawaran Sebelum gua

play00:10

menjelaskan Lebih Detail mengenai Apa

play00:11

yang dimaksud dengan permintaan dan Apa

play00:14

yang dimaksud dengan penawaran gue

play00:15

pengen menjelaskan terlebih dahulu

play00:17

supaya teman-teman lebih mengenal Apa

play00:20

itu permintaan dan penawaran Jadi kenapa

play00:22

sih bisa terjadi permintaan dan

play00:25

penawaran dalam ilmu ekonomi jadi

play00:27

misalnya ya seperti ini pernah kasih

play00:30

teman-teman itu mengamati bahwa misalnya

play00:33

dalam hal menjelang hari raya Ya

play00:35

misalnya hari raya Idul Fitri Kenapa sih

play00:37

ketika menjelang hari raya idulfitri itu

play00:40

harga kebutuhan pokok itu melambung

play00:41

tinggi

play00:42

atau misalnya contoh yang lainnya dalam

play00:46

apa di suatu daerah ya di suatu daerah

play00:48

misalnya sulit mendapatkan air bersih

play00:51

sehingga air bersih yang sulit

play00:54

didapatkan itu akan mendorong tingkat

play00:56

harga yang menjadi tinggi Nah kenapa

play00:58

bisa terjadi seperti itu Nah harga gigi

play01:01

tersebut itu

play01:04

disebabkan oleh ketidakseimbangan dari

play01:08

jumlah permintaan dan jumlah penawaran

play01:11

sehingga akan mendorong tingkat harga

play01:14

yang melambung tinggi dan bisa juga

play01:16

menyebabkan kelangkaan Nah kenapa bisa

play01:18

juga menyebabkan kelangkaan karena

play01:21

kelangkaan itu terjadi jumlah permintaan

play01:24

yang sangat banyak itu tidak diimbangi

play01:27

dengan jumlah penawaran yang jumlahnya

play01:28

itu hanya terbatas ya gitu nah itu jadi

play01:32

kenapa bisa timbul kelangkaan seperti

play01:34

itu jadi alat pemuas kebutuhan manusia

play01:36

itu jumlahnya terbatas tapi kebutuhan

play01:39

dan Keinginan manusia itu juga tidak

play01:41

terbatas Bayangkan saja Misalnya

play01:44

Katakanlah di penduduk di surga ini kan

play01:48

sekitar tujuh miliar yaitu karena

play01:51

kebutuhan manusia yang akan ataupun

play01:54

Keinginan manusia itu kata karena butuh

play01:56

yang namanya makan tapi keinginan makan

play01:59

mereka itu berbeda-beda ada yang ingin

play02:00

makan Hai ayam goreng ada ingin makan

play02:04

mie goreng ataupun mau makan di ikan

play02:06

goreng nah seperti itu Nah sehingga

play02:08

permintaan dan penawaran ini bisa

play02:11

terjadi karena adanya interaksi antara

play02:14

pembeli dengan penjual kayak gitu dalam

play02:16

hal-hal circular flow begitu dalam Alpha

play02:20

arus perputaran ekonomi kayak gitu nah

play02:23

sekarang kita masuk ke

play02:25

pengertiannya gitu ya Nah disini gue

play02:28

tulisannya dimensi gitu ya Gmail atau

play02:30

permintaan ini Yadin ataupun permintaan

play02:33

ini misalnya kalau misalnya kok

play02:37

teman-teman bayangkan ya tadi kan

play02:39

dimensi itu seorang konsumen gitu ya

play02:42

seorang konsumen yang membutuhkan ya

play02:45

atau menginginkan suatu produk ya untuk

play02:49

bisa dibilang dia itu ingin mendapatkan

play02:51

kepuasan kayak gitu ya jadi yang

play02:54

dinamakan kosmitu bukan hanya membeli

play02:55

tapi yang dinamakan konsumen itu membeli

play02:58

dan menghabiskan nilai guna suatu barang

play03:00

the pembeli nih ya kan teman-teman saya

play03:03

beli Katakanlah beli Indomie ya kan ya

play03:07

kan kata kamu Indomie goreng nah Apakah

play03:09

hanya sebatas membeli ya kan kan enggak

play03:11

Tapi apa teman-teman makan gitu kan Nah

play03:15

itu yang dimaksud dengan menghabiskan

play03:17

nilai guna suatu barang gitu ya

play03:19

sedangkan kalau misalnya disuplai atau

play03:21

penawaran yakni

play03:24

tawaran itu menawarkan ya kalau dengan

play03:27

permintaan itu dia tuh meminta atau

play03:28

membeli kalau dari sisi produsen yaitu

play03:31

menawarkan barang atau jasa nah tujuan

play03:35

dari seorang produsen itu bukan hanya

play03:37

menjual barang ya bukan hanya

play03:39

menghasilkan barang tapi Apa tujuan

play03:42

akhir dari seorang produsen itu yaitu

play03:45

mendapatkan

play03:46

keuntungan ya menjadi perbedaannya

play03:50

disitu kalau dari sisi

play03:52

apa tuh namanya

play03:55

permintaannya itu Katakanlah yaitu ke

play03:59

ingin

play04:01

ya menghabiskan juga nilai guna suatu

play04:03

barang tapi kalau dari penawaran itu

play04:05

ingin mendapatkan keuntungan yaitu

play04:07

perbedaannya

play04:09

Hai nah dalam permintaan sendiri itu

play04:13

mempunyai hukum permintaan ya kalau

play04:16

dihukum premium permintaan itu bunyinya

play04:18

ya Jika harga naik maka permintaan turun

play04:22

ya Begitupun sebaliknya Nah kenapa bisa

play04:25

demikian Kok bisa sih kalau gitu ya

play04:27

harga naik itu mendorong permintaan yang

play04:31

semakin berkurang atau semakin turun Nah

play04:35

jadi kayak gini namanya

play04:37

konsumen-konsumen itu pasti menginginkan

play04:40

Ia menginginkan ataupun ingin

play04:43

mendapatkan barang yang berkualitas tapi

play04:46

di itu ingin mengorbankan sejumlah

play04:48

uangnya dengan jumlah yang sedikit itu

play04:50

kalau konsumen ya kan secara secara

play04:54

realita banyak ya Kayaknya seperti itu

play04:56

Jadi apa kita pengin yang dapat sesuatu

play04:58

yang Katakanlah bagus ya Bisa

play05:00

teman-teman Pengen dapetin handphone

play05:02

yang bagus tapi dengan harga yang murah

play05:05

nah seperti itu makanya Pak contoh

play05:07

sederhananya apa pas ada Estelle gitu ya

play05:11

sorry apa kalau misalnya gua

play05:14

gue baca huruf s gitu ya Tokyo ataupun

play05:17

ngomong huruf F itu gua agak cadel kayak

play05:19

gitu nah misalnya pasta gigi freestyle

play05:22

gitu kan Nah pas lagi pesta itu kan

play05:24

harga lebih murah ini contoh sederhana

play05:26

yang harga lagi murah kan Terus apa itu

play05:29

mendorong konsumen yang akan mendorong

play05:31

konsumen untuk membeli produk tersebut

play05:33

anak harga lagi murah banget nih Nah itu

play05:35

contoh sederhana dari permintaan

play05:38

ataupun sebaliknya ya kalau harga lagi

play05:42

Hai apa naik ya udah permintaannya turun

play05:45

ataupun tadi harga lagi turun

play05:46

permintaannya naik ini gue Tulis secara

play05:50

matematiknya biar kalian terbiasa ya

play05:52

kalau misalnya Tidy soal soal soal

play05:54

SBMPTN ya kalau misalnya ada kata-kata

play05:57

pede gitu ya itu maksudnya price of the

play05:59

main HP dia naik maka qd turun nak Ide

play06:03

ini adalah quantity of demand Ya PD

play06:07

turun Maka qd nya naik ya seperti itu

play06:12

teman-teman ya

play06:13

Nah ini yaitu sifatnya apa berarti

play06:16

berbanding terbalik

play06:21

oke teman-teman itu mengenai loooove

play06:24

dimensi Nah kalau mengenai loooove

play06:26

Supply ya kalau of supply ini berarti

play06:28

hukum penawaran Nah kalau dihukum

play06:32

permintaan tadikan Deal berbanding

play06:33

terbalik hukumnya Ya tapi kalau di hukum

play06:35

penawaran

play06:36

Yadi penawaran ini hukumnya berbanding

play06:39

lurus bunyinya Jika harga naik maka

play06:43

penawaran juga ikut naik gitu ya

play06:46

sedangkan Jika harga turun maka

play06:49

penawaran ikut turun juga kayak gitu nah

play06:52

Kenapa demikian kalau produsen itu

play06:55

mengejar keuntungan

play06:57

Oke kalau perutnya tujuannya

play07:00

memaksimalkan laba atau keuntungan

play07:03

ya yaitu memaksimalkan laba atau

play07:06

keuntungan yang di mana Kalau di itu

play07:08

ingin mendapatkan keuntungan-keuntungan

play07:10

yang besar maka dia itu menjual harga

play07:14

Hai barang ya ataupun produknya itu

play07:16

dengan harga yang mahal kayak gitu

play07:18

makanya dari sisi produsen ataupun

play07:22

penjual Ya misalnya nih pemerintah

play07:24

menaikkan harga beras gitu ya atau

play07:26

pemerintah menaikkan harga sembako gitu

play07:29

kan menit meningkat kehidupan misalnya

play07:31

kayak gitu nah kita produsen ataupun

play07:34

penjual karena

play07:36

sembako itu kata kala itu kebutuhan

play07:38

pokok bagi konsumen ya Ho harga naik nih

play07:42

Itu kecepatan dari sisi penjual itu

play07:45

harga lagi naik nih gue tablet

play07:46

keuntungan yang besar kayak gitu ya tapi

play07:49

apa dari sisi konsumen Ya kan karena ini

play07:53

kebutuhan pokok ya mau nggak mau dia

play07:56

bakal tetap beli gitu kan namanya juga

play07:58

Katakanlah masyarakat Indonesia itu

play08:01

dominannya itu makan nasi akhirnya apa

play08:04

de itu pasti dengan harga beras yang

play08:07

meningkat bakal tetap dibeli kayak gitu

play08:09

ya Nah itu dari hukum penawaran

play08:11

berbanding lurus

play08:13

Indonesia

play08:15

Hai Oke kalau misalnya secara matematis

play08:18

ditulis ya PPS ya berarti PS itu price

play08:21

of Supply

play08:23

Oh ya apa harga yang ditawarkan kau

play08:27

dengan pede itu price of the main harga

play08:29

yang diminta maka qwerty quantity of

play08:33

supply itu ikut naik juga

play08:36

lalu PS turun

play08:39

Hai maka Kya juga ikut turun juga head

play08:43

seperti itu ya Jadi kalau di penawaran

play08:45

berbanding terbalik Sorry kalo di

play08:49

penawaran berbanding lurus sedangkan

play08:50

kalau di permintaan itu berbanding

play08:52

terbalik

play08:54

hai oke

play08:56

itu yang mengenai hukum permintaan dan

play08:58

hukum penawaran dalam

play09:01

permeabel dalam konsep permintaan dan

play09:03

penawaran selanjutnya kita akan masuk ke

play09:07

schedule ya skedul permintaan

play09:09

dan hukum

play09:12

Oh ya gitu permintaan dan kurva

play09:13

permintaan

play09:16

the lounge

play09:18

Kya skedul permintaan

play09:21

Hai dan kurva permintaannya jadi ini

play09:27

jadi kalau dalam ekonomi itu mungkin

play09:29

yang membedakan dengan

play09:32

materi soshum yang lain itu di kurva

play09:35

komite ekonomi pada kurva menjadi apa

play09:37

kurva ini nanti lebih ke apa ya Di itu

play09:41

tapi yang memberikan ataupun memberikan

play09:43

informasi ya jadikan kalian harus bisa

play09:45

interprestasi dari kurva tersebut ya ini

play09:49

biar kalian tahu ya dalam hal membaca

play09:52

kurva permintaan itu seperti apa kayak

play09:54

gitu Ini gue sambil buat tabelnya ya

play10:04

Hai keju sini gue bikin

play10:09

ke-2 kolom ya gue bikin 2 kolom yaitu

play10:13

ada

play10:15

A100 ya berarti ketika harga 100 jumlah

play10:18

barang yang diminta 50 ketika harga

play10:22

120 jumlah barang yang diminta itu 40 ya

play10:27

dan ketika harga

play10:29

140 jumlah barang yang diminta itu 30

play10:34

ketika harga 160 jumlah barang yang

play10:36

diminta 20 dan ketika harga 180 jumlah

play10:40

barang yang diminta nya 10 jadi schedule

play10:43

itu merupakan tabel ya tabel dalam

play10:45

permintaan nah tabel ini nanti akan

play10:48

disajikan dalam bentuk kurva

play10:50

permintaannya

play10:53

Hai nah di permintaan

play10:56

kalau misalnya kita lihat ya bentuk

play10:58

kurvanya itu bergerak ya bergerak

play11:02

Hai HD itu bergerak turun dari kiri atas

play11:06

turun ke kanan bawah ya kenapa tadi ya

play11:10

sesuai dengan Hukum

play11:13

permintaannya ya kan sesuai dengan Hukum

play11:15

permintaannya ketika harga naik

play11:17

permintaan nya turun kayak gitu ya nah

play11:22

makanya apa dalam hal kurva permintaan

play11:26

yaitu disebutnya dengan atau diesel itu

play11:30

dengan downward-sloping ya

play11:32

downward-sloping gitu yang berarti Apa

play11:35

itu memiliki kemiringan yang negatif

play11:37

kayak gitu atau dia itu bergerak ya tadi

play11:39

dari kiri atas turun ke kanan bawah

play11:45

Hai lovebird ini ya Nah makanya di sini

play11:48

kalau misalnya gue Tulis secara

play11:50

matematis ya Gue tulis secara matematis

play11:53

ya ketika deltapack ya berarti itu

play11:55

perubahan harga karena apa tadi kan di

play11:57

sini ada masih sedikitnya ada lima harga

play11:59

nih dan harga itu mengalami perubahan

play12:01

hedel tak pepper diotaki misalnya Delta

play12:06

v nya itu naik nah ini go simbolkan

play12:09

positif gitu ya sedangkan kalau misalnya

play12:13

Delta kynya turun akan turun berarti itu

play12:16

negatif sama kapas secara matematis

play12:20

positif dibagi negatif

play12:22

= negatif makanya dalam kurva permintaan

play12:25

yaitu memiliki kemiringannya negatif

play12:29

Oh ya ya Hai atau dalam

play12:33

Hai hal tapi itu itu p2win P1 Hotman

play12:38

perhatikan berarti kalau p2win P1 ya kan

play12:42

bisa katakan harga barang keduanya itu

play12:43

120 ya Min 100 berarti kan positif 20

play12:50

yaitu lebih besar dari nol sedangkan

play12:53

kalau misalnya teman-teman perhatikan

play12:56

juga Q2 nyata di ketika keduanya itu

play13:01

120 maka keduanya akan

play13:03

40 ya Kan Sudah Kan kalau Q1 nya itu

play13:06

Katakanlah

play13:07

100 ya Ki satunya itu 100 berarti

play13:12

quantity yaitu 5640 kurang 50 maka

play13:16

negatif 10 yaitu kurang dari nol

play13:20

gitu ya ini penerapan kurva permintaan

play13:23

secara matematisnya

play13:27

Oke Enggak enggak rumit ya Apa mungkin

play13:30

ini pernah kalian pelajari gitu ya ini

play13:32

di kelas 10 materi skedul permintaan dan

play13:36

kurva permintaan selanjutnya kita masuk

play13:39

ke skedu penawarannya dan kurva

play13:41

penawaran Naik kau tadi teman-teman

play13:43

perhatikan bahwa kalau di permintaan itu

play13:46

di itu memiliki kemiringan yang negatif

play13:48

ya kalau misalnya di penawaran tuh

play13:50

kemiringannya Apakah sama kayak

play13:51

permintaan atau berbeda ya kayak gitu

play13:55

nah ini sambil gua gambar ya

play13:58

apa tabelnya atau schedulenya dan

play14:01

kurvanya nanti oke

play14:05

Indonesia generasi kalau di SBMPTN nanti

play14:08

materi ini sih memang sering keluar

play14:10

kayak gitu tapi yang sering keluarnya di

play14:14

materi ini bukan hanya hukumnya ya tapi

play14:18

juga kayak dari sisi Katakanlah Kenapa

play14:21

kurva permintaan itu Bisa bergeser

play14:22

Kenapa kurva penawaran itu Bisa bergeser

play14:25

ya Apa aja sih faktor-faktor yang

play14:27

membuat kurva tersebut Bisa bergeser ke

play14:30

kanan atau ke kiri ya nanti itu

play14:33

pembahasan Selanjutnya ya Jadi sekarang

play14:35

gue pengen ngejelasin ke konsepnya dulu

play14:38

kayak gitu

play14:40

Oh ya di sini kalau kalian lihat Yap

play14:42

ketika harganya 200 maka jumlah barang

play14:47

yang ditawarkan 100 ketika harganya 400

play14:50

jumlah barang yang ditawarkan 150 lagi

play14:52

semakin meningkat nih sesuai dengan

play14:53

hukum penawaran ketika harganya 600

play14:56

jumlah barang yang ditawarkan 200 ketika

play14:59

harganya 800 jumlah barang yang

play15:02

ditawarkan 250 dan ketika harganya

play15:05

seribu jumlah barang yang ditawarkan 300

play15:08

kayak kita lihat Nikita Perhatian apa

play15:11

kita

play15:13

Hai mulai gambar ya kurva penawarannya

play15:15

ya di sini kalau teman-teman perhatikan

play15:18

Apakah

play15:19

kurvanya itu berbeda dari kurva

play15:21

permintaan atau

play15:23

sama kayak gitu

play15:26

oke Ini gue sambil gambar Nah di sini

play15:30

kalau misalnya teman-teman Perhatikan ya

play15:34

pasti berbeda gitu kan karena sesuai

play15:37

dengan hukumnya juga kurva penawaran itu

play15:40

memiliki beberapa memiliki

play15:42

bentuk kurva yang dia itu bergerak ya

play15:46

dari kiri bawah ya kan naik ke kanan

play15:50

atas oke Kenapa bisa berbeda karena tadi

play15:55

ya kita baiknya ke hukumnya Kalau hukum

play15:58

penawaran harga naik jumlah penawarannya

play16:02

ya atau barang yang tawarkan yaitu juga

play16:04

ikut naik

play16:06

hai oke kayak gitu nah Berarti Apa

play16:09

karena dia itu berbanding lurus maka

play16:12

dalam kurva penawaran yaitu memiliki

play16:16

Hai kemiringan yang positif ya karena

play16:19

tadi itu bergerak dari kiri bawah naik

play16:22

ke kanan atas atau Appworld sloping he

play16:26

maka secara matematis

play16:27

ini berbeda dengan

play16:30

tadi kurva permintaan ya kalau secara

play16:33

matematis maka perubahan atau deltapack

play16:36

nya ya itu ketika Adel tape-nya naik

play16:41

maka perubahan kimia di berikut naik ke

play16:43

gitu ya makanya Pak Ditiro teman-teman

play16:46

perhatikan ketika Delta v nya itu

play16:49

Katakanlah 200 ke-400 naik ya dari 200

play16:53

ke-400 berarti Naik 200 maka Abah yang

play16:57

tadinya jumlah barang yang ditawarkan

play16:58

yaitu 100 itu juga meningkat menjadi 150

play17:02

tadi sini ini maka Apa karena dia itu

play17:05

meningkat

play17:06

dua-duanya ya PSnya meningkat Kya juga

play17:10

meningkat maka positif dibagi positif

play17:13

hasilnya positif seperti itu ya

play17:16

sebaliknya kalau PSnya turun maka QS

play17:20

juga ikut turun negatif dibagi negatif

play17:22

hasilnya positif kayak gitu nah dcp2

play17:26

mint P1 lebih besar dari nol ya kenapa

play17:30

tadi v2nya katakan 400 dikurang P1 y200

play17:34

berarti kan positif 200 itu dari nol

play17:37

keduanya mint kita tuh juga lebih besar

play17:39

dari nol Kenapa Kidul khas 50j kurang

play17:43

100 jadi 50 kan enggak 50 itu berarti

play17:46

lebih besar dari

play17:50

Hai Hah gitu ya Apa jadi itu

play17:52

perbedaannya dari kurva permintaan dan

play17:56

kurva penawaran ya jadi teman-teman

play17:59

harus

play18:00

Tamiya itu perbedaannya Oke ini konsep
