Introduction

Water is a vital resource for human survival, used in various aspects such as agriculture, households, industry, and offices. In many areas, especially those in the countryside or suburbs, people still rely on surface water, such as river water, as a source of clean water. Unfortunately, the use of water without adequate processing can increase turbidity and total suspended solid (TSS) in water. To overcome this problem, various clean water treatment techniques are employed, including physics, chemical, and biological treatment.

The Importance of Coagulation and Flocculation in Water Treatment

One of the crucial methods of water treatment is the process of coagulation and flocculation. This process serves to stabilize colloids in water by adding chemicals known as coagulants. The effectiveness of coagulants in reducing turbidity and TSS levels is a critical factor in determining the quality of clean water. In this study, we aim to evaluate the effectiveness of biocoagulants originating from tamarind seeds (Tamarindus indica) and durian seeds (Durio zibethinus) in reducing turbidity and TSS levels, as well as comparing them with alum, which is one of the chemical coagulants commonly used.

The Jar Test Method: A Standardized Procedure for Coagulation and Flocculation

The process of coagulation and flocculation in this study was carried out using the jar test method. This method involves adding coagulants to water samples and agitating them for a specified period to allow the coagulants to work effectively. The test results show that biocoagulants from tamarind seeds can reduce turbidity levels to 97.67% and TSS by 96.56% at pH 7.0, which is expressed as the best pH. Meanwhile, biocoagulants from durian seeds show the ability to reduce turbidity by 91.99% and TSS 89.5% at the same pH, as well as at pH 5.5, can reduce turbidity to 92.69% and TSS by 92.21%.

Comparative Analysis of Tamarind Seeds and Durian Seeds as Biocoagulants

Analysis of the results of this study shows that tamarind seeds are more effective in reducing turbidity and TSS than durian seeds. This can be caused by the content of active compounds in tamarind seeds that are superior in the coagulation process. These compounds can act as more efficient binding agents in gathering suspended particles in water, thereby increasing the water purification process.

The Benefits of Using Natural Biocoagulants

The use of natural biocoagulants is very profitable, especially for people who are in areas that lack access to modern water treatment technology. By using natural ingredients available around, such as tamarind seeds and durian seeds, people can not only get clean water, but can also reduce water treatment costs. In addition, the use of natural biocoagulants is also more environmentally friendly compared to chemical coagulants, which often leave dangerous residues.

Conclusion

In conclusion, this study shows that tamarind seeds and durian seeds have the potential as biocoagulants in the process of coagulation and flocculation to process surface water. The use of natural ingredients can provide effective and sustainable solutions to improve the quality of clean water in the community, especially in areas that still rely on surface water as the main source.
