Q & A

What is the main purpose of the video?

The main purpose of the video is to demonstrate the process of Total Suspended Solids (TSS) testing on wastewater by students of SMKN 1 Cibadak.

What safety measures are students required to take before conducting the test?

Students are required to remove accessories, use hand sanitizer, and wear personal protective equipment (PPE) including masks, gloves, and lab coats.

What procedure is used for the TSS testing?

The TSS testing is conducted using the SNI 0669 89.3 standard procedure from 2004, which involves several steps to measure the Total Suspended Solids in the wastewater sample.

How is the wastewater sample prepared for testing?

The wastewater sample is homogenized using a magnetic stirrer after being placed in a beaker glass, and 100 ml of the sample is then used for the test.

What equipment is necessary for the TSS testing?

Equipment needed includes a beaker glass, magnetic stirrer, Erlenmeyer flask, filtration apparatus, vacuum pump, oven, desiccator, and analytical balance.

How is the TSS measurement process initiated?

The process begins by filtering the homogenized sample through filter paper using a vacuum pump, followed by drying the filter paper in an oven and weighing it to determine the TSS concentration.

How long does the drying process take, and at what temperature?

The drying process takes one hour at a temperature of 105 degrees Celsius.

What is the significance of the TSS value obtained from the test?

The TSS value indicates the concentration of suspended solids in the wastewater, which is crucial for determining compliance with environmental standards.

What is the standard limit for TSS in industrial wastewater according to the 2014 regulation?

According to Permen LH No. 5 of 2014, the standard limit for TSS in industrial wastewater is 30 mg per liter.

What was the TSS result for the wastewater sample, and did it meet the required standard?

The TSS result for the wastewater sample was 6.8 mg per liter, which meets the required standard of 30 mg per liter.
