“…Ghebremechael, Kebreab (2009) mengklasifikasi koagulan menjadi dua yaitu koagulan organik dan koagulan anorganik [6]. Koagulan yang umum digunakan di kalangan masyarakat adalah koagulan anorganik seperti tawas (Al2(SO4)3) [7] dan FeCl3 [8], Poli Aluminium Klorida (PAC) [9]. Ozacari (2003) menyatakan bahwa koagulan jenis ini dapat memicu timbulnya penyakit Alzheimer [10].…”

Sungai Kahayan memiliki arti penting bagi masyarakat sekitar dalam memenuhi kebutuhan sehari-hari. Ambang batas normal nilai kekeruhan air sungai adalah sebesar 50 NTU, sementara nilai kekeruhan air Sungai Kahayan saat ini telah mencapai 86,10-150 NTU. Metode untuk menurunkan tingkat kekeruhan air telah banyak dikembangkan, salah satunya adalah dengan metode koagulasi. Tumbuhan Hanjeli (Coix lacryma jobi L) adalah salah satu tanaman liar di Kalimantan Tengah. Tumbuhan Hanjeli sering dijumpai di pinggir-pinggir sawah, pekarangan rumah, di pinggir sungai, dan di pinggir jalan. Biji Hanjeli memiliki kandungan protein 12,26% , dan Karbohidrat 74,36%. Kandungan Protein pada biji Hanjeli dapat dipertimbangkan sebagai koagulan dalam proses penjernihan air Sungai Kahayan. Penambahan koagulan serbuk biji hanjeli kedalam air sungai Kahayan dapat mempengaruhi nilai kekeruhan dan sedikit pada pH air. Massa optimum koagulan yang diperlukan untuk menyisihkan kekeruhan air adalah sekitar 0,2 gr/L. Ukuran koagulan optimum untuk menyisihkan kekeruhan air adalah 80 mesh. Kondisi efektif untuk penyisihan turbiditas dan pH air yang paling baik adalah dengan massa koagulan biji hanjeli 0,2 gr/L dan ukuran partikel 80 mesh dengan penyisihan turbiditas sebesar (94%) dan penuruhan pH sebesar (3,6%)

“…The coagulation and flocculation process removes TSS by adding a coagulant and rapidly stirring it to neutralize (destabilize) suspended particles and colloids in water that have a negative charge and are less than 1 µm in size, forming microflocs that are not visible to the naked eye and range in size from 1 to 100 µm. Brownian force causes microflocs to collide, and subsequently they bind together to form larger aggregates (peri-kinetic flocculation) [8].…”

River has a vital role to fulfill the water needs of the community. In the water bodies, the small suspended particles, also known as colloids, with the small weight and stability in the water bodies they have, they cannot be settled or eliminated naturally. There are some concerns regarding colloid removal in Kalimalang river, such as increase in water turbidity resulting the decrease in the river water quality as a water source and disruption of the ecosystem in the river. The experiment used poly-aluminum chloride (PAC) as the coagulant and jar test method which contains coagulation-flocculation process. This aims to determine optimal dosage of PAC to reduce the turbidity and pH value of water sample that relate to the regulation of water quality standard for sanitary hygiene, which is regulated by law No 32 Year 2017. The optimum dose for this experiment is 2 mg/L PAC 0.5 percent as the sample achieved the lowest average of turbidity that is 0.02 NTU with the average of pH is 7, indicating that the sample meets the quality standards of Environmental Health Quality Standards for sanitary hygiene purposes.
