play01:20

kuliah kita hari ini

play01:22

melanjutkan topik terdahulu

play01:25

terkait dengan prinsip dasar penerapan

play01:29

mikroba dalam industri ya kita sudah

play01:31

pelajari minggu yang lalu bahwa

play01:33

mikrobiologi industri atau berkaitan

play01:36

dengan penerapan mikroba

play01:38

yang ekonomis dalam skala industri Kya

play01:44

Hai kembali ke topik kita penerapan

play01:47

mikroba tersebut melalui proses yang

play01:49

kita sebut fermentasi dari ya tentunya

play01:52

ada

play01:53

kalau mau dibuat garis besar ada

play01:56

bahan baku yang menjadi substrat atau

play01:59

media mikroba yang akan diterapkan

play02:02

kemudian ada proses

play02:05

di pasar mentasi

play02:08

yang mana terjadi proses biokimia karena

play02:12

tumbuhnya mikroba disitu

play02:15

menyebabkan perubahan substrat tempat

play02:18

tinggalnya tadi tempat tumbuhnya tadi

play02:21

Nah kemudian akhirnya setelah karena si

play02:25

selesai atau dihentikan maka hak dari

play02:28

produk yang harus kita

play02:30

recovry atau kita ambil video

play02:35

Hai nah produk fermentasi

play02:37

sudah sekilas dijelaskan di perkuliahan

play02:41

sebelumnya banget bisa kita golongkan

play02:42

menjadi empat ya cepat golongannya

play02:45

produknya bisa berupa biomassa Sutra itu

play02:49

contohnya tadi yang digambar tadi ya Ada

play02:51

peras kemudian menjadi angkat kemudian

play02:55

kedelai menjadi tempe

play02:57

singkong Kemudian ubi singkong menjadi

play02:59

pakai ya berarti biomassa Supra

play03:05

hai hai Ayo kita

play03:09

ah ah

play03:11

Hai yang agak rumit adalah pada produk

play03:16

metabolit ya karena kalau yang mau

play03:19

diambil metabolit maka kita harus

play03:21

memurnikan

play03:25

Hai hasil dari penutup presentasi itu

play03:28

dari sel mikrobanya dan juga sisa-sisa

play03:31

sel

play03:32

substrat atau medianya ya

play03:35

Nah metabolit itu

play03:39

Hai dikenal dengan metabolit primer dan

play03:42

metabolit sekunder

play03:44

dan terbentuknya Pada fase-fase

play03:47

pertumbuhan sel mikroba tersebut ya

play03:50

Nah metabolit primer itu terjadi

play03:53

terutama di fastlog dan ciri khasnya

play03:57

adalah dia mengikuti kurva pertumbuhan

play03:58

ya

play04:00

artinya terjadi peningkatan produksi

play04:02

metabolitnya disini Tapi nanti kalau

play04:04

sudah pas estacion er sudah tidak nambah

play04:07

lagi Ya

play04:09

tidak nambah lagi jumlahnya daftar ya

play04:13

Nah kebalikannya pada

play04:15

metabolisme onder itu justru akan

play04:22

Hai terbentuk secara

play04:24

signifikan itu di awal fase stasioner

play04:29

Hai ini dipakai saya suami semakin

play04:31

tinggi semakin tinggi produknya Sebagai

play04:34

contoh untuk metabolit sekunder adalah

play04:37

antibiotik ya kemudian Kalau yang ini

play04:41

contohnya adalah asam laktat

play04:45

Hai tak silakan dijatah

play04:48

untuk tugas setelah kuliah Ini

play04:51

pertama

play04:53

cari contoh-contoh metabolit primer dan

play04:57

metabolit sekunder ya Selain yaitu

play04:59

Contohkan tadi ya

play05:01

Hai kemudian Sebutkan mikroba apa saja

play05:05

yang memproduksi itu ya

play05:09

Hai sudah bisa dipahami tugasnya halo

play05:19

Hai

play05:19

dari diagram

play05:21

proses fermentasi tadi kita bisa

play05:24

sama rekan bahwa

play05:27

paling tidak ada

play05:30

lima yanima item yang harus dikontrol

play05:34

dan dikendalikan ya karena kita ingin

play05:36

produk fermentasi kedalah produk yang

play05:38

sesuai bukan produk yang busuk yang

play05:43

tidak terkontrol pertama tentu adalah

play05:45

mikrobanya sendiri ya karena mikroba ini

play05:47

akan kita terapkan didalam proses

play05:50

fermentasi atau disebut juga dengan

play05:53

kultur fermentasi

play05:55

kemudian kultur fermentasi membutuhkan

play05:58

media pertumbuhannya

play06:00

Hai atau substrat ya dalam hal ini kalau

play06:03

Bahannya seperti tarian

play06:06

yang akan di carmenta SI maka bahan

play06:08

hasil pertanian tersebut menjadi

play06:10

substrat ya

play06:12

Hai nah tentu saja media ini nanti akan

play06:14

menjadi di dalam industri ada dua ya

play06:17

media fermentasinya bisa juga media

play06:20

untuk memperbanyak kulturnya ini tadi ya

play06:24

kita sebut media pertumbuhan media untuk

play06:27

memperbanyak kulturnya tadi sebelum di

play06:29

fermentasi

play06:32

Hai kok model tentunya perlu pengaturan

play06:36

selama proses ya bagaimana oksigennya

play06:38

suhunya ph-nya dan sebagainya

play06:41

nah yang tidak kalah pentingnya adalah

play06:44

nanti sistem fermentasi ya Jadi apakah

play06:47

proses fermentasi tersebut cocoknya

play06:49

dilakukan secara kontinyu atau

play06:52

dilakukan pengumpanan substratnya secara

play06:56

periodik ya atau dikenal dengan head

play06:58

back atau bagusnya secara baksya jadi

play07:02

penyiapan sekali sampai akhir kemudian

play07:04

selesai

play07:07

kemudian yang tidak kalah pentingnya

play07:10

adalah setelah di fermentasi adalah

play07:12

bagaimana proses recovery produknya ya

play07:15

bagaimana proses memanen produknya ya

play07:17

mengisolasi produk yang diinginkan ya

play07:20

tentunya akan berbeda kalau produknya

play07:23

itu tadi

play07:25

Hai

play07:27

metabolit dengan kalau produknya adalah

play07:30

sih media yang di fermentasi ya atau

play07:34

substrat atau bahan baku atau pertanian

play07:37

dalam hal

play07:39

fermentasi padat itu cenderung yang mau

play07:42

diambil adalah medianya ya Nah itu

play07:46

recovery atau pengembalian pengambilan

play07:49

produknya relatif lebih muda ya bisa

play07:51

kita bayangkan bisanya pada fermentasi

play07:52

tempe

play07:54

dari kedelai kan akan mudah memanen

play07:57

kedelai nya ya karena semua tinggal

play07:59

diangkutnya demikian juga tape

play08:03

Hai dan menjadi

play08:05

Kompleks untuk kalau yang mau diambil

play08:08

adalah Misalnya antibiotiknya atau

play08:10

enzimnya ya Nah itu akan dipelajari di

play08:13

proses Hilir ya

play08:17

hai hai

play08:19

Hai Dr Cita akan membahas yang pertama

play08:21

kultur fermentasi dari berkembang di

play08:25

zaman Louis Pasteur ya Karena pada saat

play08:29

itulah

play08:30

terjadi penemuan bawah ternyata proses

play08:34

fermentasi itu yang berperan adalah

play08:36

mikroorganisme

play08:38

sehingga perlu pengontrolan mikrobanya

play08:40

itu yang akan digunakan

play08:42

Nah setelah itu mulai berkembang

play08:44

penyiapan kultur untuk industri susu ya

play08:53

hai hai Hai

play08:55

nah kaitannya dengan kultur starter yang

play08:59

digunakan di fermentasi maka akan kita

play09:01

kenal istilah dengan fermentasi spontan

play09:03

dan cara mengatasi dengan penambahan

play09:06

kultur starter

play09:08

contoh pada tempe Apakah ada penambahan

play09:12

kultur starter pada pengolahan tempe

play09:18

Hai ada bu dhe ya

play09:22

Hai Nah karena ada maka kita sebut

play09:25

dengan

play09:27

Hai Fermentasi yang

play09:30

terkontrol ya artinya ada penambahan

play09:32

kultur transfer nah fermentasi spontan

play09:35

itu contohnya pada pembuatan tempoyak ya

play09:39

biasanya tidak ditambahkan starter

play09:42

itu bisa jadi fermentasi Apakah tidak

play09:45

ada mikroba yang tumbuh aja ya kita kan

play09:47

tadi sudah belajar bahwa kita fermentasi

play09:49

itu adalah proses biokimia yang mana ada

play09:53

mikroba tumbuh di situ ya

play09:55

ngambil energi supaya dia tumbuh dan

play09:57

sebagainya nah Biasanya karena mikroba

play10:00

kan tidak tampak oleh mata kita ya Jadi

play10:03

pada fermentasi spontan

play10:07

Hai proses yaitu mengkondisikan mikroba

play10:09

tertentu tumbuh ya jadi bisanya pada

play10:12

karena ntasi tempoyak tadi duriannya

play10:14

ditambahkan garam kondisi yang asing itu

play10:17

itu mengkondisikan untuk bakteri asam

play10:20

laktat

play10:21

bisa tumbuh ya Jadi yang terperangkap di

play10:23

dalam media di dalam

play10:27

wadah fermentasinya jadi kita tahu

play10:31

tertentu Asia seperti itu kan ada space

play10:32

udara biasanya ya Atau bisa juga Memang

play10:36

mikroba itu ya

play10:37

secara alami tumbuh di

play10:40

dalam daging durian tersebut ya karena

play10:43

sudah terbuka

play10:44

nah kondisi penambahan garam itu

play10:47

mengkondisikan mikroba bakteri asam

play10:50

laktat akan tumbuh ya

play10:52

tentunya yang spontan biasanya

play10:56

selain yang diinginkan juga ada

play10:59

kontaminan juga ya ikut tunggu ya karena

play11:01

kan namanya secara spontan yang tidak

play11:04

kita kontrol penambahan starternya Hai

play11:07

nah ini kita bisa lihat di hasil

play11:12

Hai pengamatan

play11:14

di antara tradisional dan fermentasi

play11:18

yang lebih modern yang sudah ada

play11:20

modifikasinya

play11:23

hai hai

play11:29

hai hai

play11:32

Hai Nah itu menunjukkan bahwa ke kalau

play11:34

yang tradisional tadi e-lab ini adalah

play11:37

lactic acid bacteria atau bakteri asam

play11:40

laktat jadi pada fermentasi Ini

play11:42

dibutuhkan bakteri asam laktat ya

play11:45

dan juga hamil

play11:50

Hai pada proses tradisional ternyata

play11:53

jumlahnya sedikit deh kenapa karena itu

play11:57

tadi ya dilakukan secara spontan juga

play11:59

secara spontan

play12:01

tetapi yang sudah ditambahkan kultur

play12:04

murni ya ditambahkan sangat jelas itu

play12:08

maka jumlah bakteri asam laktat nya dan

play12:12

Samir nya juga lebih tinggi

play12:16

hai hai

play12:17

Hai Nah karena jumlahnya sudah

play12:20

memadai lebih besar jadi lebih dominan

play12:23

jadi proses fermentasinya menjadi lebih

play12:25

lancar ya menjadi produk sehingga apa

play12:28

yang terjadi

play12:28

dengan kondisi PH 4 setengah yang

play12:33

hai oh Inginkan Dia bisa produk akhirnya

play12:36

tak setengah maka yang tradisionalnya

play12:40

membutuhkan waktu sangat lama

play12:45

hai tapi kalau yang sudah dimodifikasi

play12:47

ada penambahan secara terkontrol waktu

play12:51

fermentasi menjadi lebih singkat ya jadi

play12:53

itu keuntungan dari para mutasi yang

play12:55

menggunakan kultur starter yang di

play12:57

kontrol ya dibandingkan yang tidak

play13:00

dikontrol atau spontan

play13:07

Hai Neni contoh di dalam pembuatan wine

play13:11

nya

play13:12

hai hai

play13:17

Hai

play13:24

contoh yang ini yang merah ini ada

play13:27

fermentasi secara spontan jadi ini

play13:31

artinya tumbuh sendiri ya saccharomyces

play13:33

dan

play13:35

will is Jadi kalau ini gemsnya jenis

play13:39

saccharomyces ini jenis liar ya

play13:42

tapi belum diidentifikasi apa yang

play13:45

penting dia

play13:47

teridentifikasi juga kamir hanya saja

play13:50

liar ya namanya secara spontan ia mana

play13:53

yang terperangkap itulah yang masuk

play13:56

dari abad ke-19 sudah mulai di kontrol

play14:04

Hai saccharomyces nya sudah memang

play14:06

sengaja ditambahkan yang murni ya

play14:13

Hai

play14:13

kemudian dicoba dikembangkan

play14:16

jadi kadang-kadang kalaupun menggunakan

play14:20

yang murni

play14:22

dibandingkan yang asli tadi yang banyak

play14:25

tumbuh mikroba

play14:27

kontaminan ya tapi ternyata dia second

play14:31

aroma wine yang kadang-kadang spesifik

play14:35

ya unik ya sehingga orang kembali

play14:38

mencoba

play14:40

melakukan apa yang namanya

play14:43

Hai hydratin ia jadi gabungan dari yang

play14:47

murni kemudian yang file-nya juga

play14:49

diambil ya kemudian ikut ditambahkan

play14:52

lagi

play14:54

Hai supaya hasilnya menjadi lebih baik

play14:57

ya karena kalau main ini akan lebih

play14:59

utama adalah

play15:01

Sisi citarasa dan aroma

play15:05

sehingga dijaman di era sekarang proses

play15:09

fermentasinya ini yang lebih dites suka

play15:13

iya

play15:14

campuran cat Romance yang aku

play15:17

Hai ragi yang terkontrol itu tadi

play15:20

ditambahkan ragi yang dari luar ya Tapi

play15:24

tetap saja prosesnya secara terkontrol

play15:28

Hai Jeju perkembangan

play15:30

kultur starter di dalam industri wine

play15:34

MP3

play15:42

Hai

play15:44

nah kemudian dalam kultur juga

play15:47

kadang-kadang perlu digabungkan dua

play15:49

jenis yang berbeda itu dalam rangka atas

play15:52

supaya menghasilkan

play15:54

hasil atau aroma yang tidak

play15:57

Hai lebih saya

play15:59

jadi ternyata di dalam

play16:03

fermentasi produk tersebut baik bakteri

play16:06

asam laktat maupun kamir ini terjadi

play16:09

Sinergi

play16:10

tak Biasanya kalau hanya lactic acid

play16:13

bacteria saja maka produk itu terlalu

play16:15

asam ya Dengan hadirnya kamir Samir bisa

play16:22

mengubah Asam Asam yang diproduksi oleh

play16:25

bakteri asam laktat ya

play16:28

untuk pertumbuhannya ya Sehingga

play16:30
