🔬 Step-by-Step Procedure for TSS Testing

This paragraph details the step-by-step procedure for testing TSS in the wastewater sample. It starts with homogenizing the sample using a magnetic stirrer and measuring 100 ml of the sample into an Erlenmeyer flask. The procedure continues with filtering the sample through a pre-washed filter paper, drying it in an oven, and weighing the filter to record the mass. The process is repeated with the vacuum pump to ensure all solids are captured, and the sample is dried and weighed again to calculate the total suspended solids.

Keywords

💡TSS (Total Suspended Solids)

Total Suspended Solids (TSS) refers to the particles that are suspended in water and can be trapped by a filter. In the video, the students are conducting an experiment to measure the TSS in wastewater, a key parameter in water quality testing. The process involves filtering the water sample and weighing the residue to determine the concentration of solids, which is crucial for assessing the environmental impact of wastewater.

💡SNI 0669 89.3

SNI 0669 89.3 is the Indonesian National Standard that outlines the procedures for conducting TSS tests. The video references this standard to ensure that the testing methods used by the students comply with nationally recognized protocols. This standardization is important for obtaining accurate and consistent results in environmental testing.

💡APBD (Alat Pelindung Diri)

APBD stands for Alat Pelindung Diri, which translates to Personal Protective Equipment (PPE) in English. The video emphasizes the importance of using PPE such as masks, gloves, and lab coats to ensure the safety of students while handling potentially hazardous materials during the TSS testing process. This is a crucial aspect of laboratory work, ensuring that students are protected from potential risks.

💡Magnetic Stirrer

A magnetic stirrer is a laboratory device used to mix liquids by creating a rotating magnetic field that spins a stir bar placed in the liquid. In the video, the students use a magnetic stirrer to homogenize the wastewater sample before testing, ensuring that the solids are evenly distributed in the solution for accurate measurement of TSS.

💡Vacuum Filtration

Vacuum filtration is a technique used to separate solids from liquids by applying a vacuum to pull the liquid through a filter, leaving the solids behind. The video demonstrates this process as part of the TSS testing procedure, where the filtered solids are later dried and weighed to determine their concentration in the wastewater sample.

💡Erlenmeyer Flask

An Erlenmeyer flask is a type of laboratory glassware with a conical shape, commonly used for mixing and heating chemical solutions. In the video, students use an Erlenmeyer flask to hold and mix the wastewater sample during the TSS testing process. Its shape helps prevent spillage during mixing, which is important for maintaining the integrity of the sample.

💡Desiccator

A desiccator is a sealed container used to protect samples from moisture by absorbing humidity. In the video, the students place the filter paper with the TSS residue in a desiccator after drying it in an oven. This step ensures that the sample remains dry before weighing, which is essential for obtaining accurate TSS measurements.

💡Permen LH No. 5 Tahun 2014

Permen LH No. 5 Tahun 2014 refers to a regulation from the Indonesian Ministry of Environment that sets the environmental quality standards, including the permissible limits for pollutants in industrial wastewater. The video mentions this regulation to highlight the importance of ensuring that the TSS levels in the tested wastewater comply with legal environmental standards, specifically the limit of 30 mg/L.

💡Analytical Balance

An analytical balance is a highly sensitive laboratory instrument used to measure mass with great precision. In the video, students use an analytical balance to weigh the filter paper before and after filtering the wastewater sample. The difference in weight helps them calculate the TSS concentration, making the balance a crucial tool in the experiment.

💡Teaching Factory

Teaching Factory is an educational concept where students participate in real-world industry-related projects as part of their learning process. The video showcases a Teaching Factory setup where students at SMKN 1 Cibadak conduct TSS testing as part of their curriculum, bridging the gap between theoretical knowledge and practical skills in environmental science.
