Abstract

Pada proses pengolahan air bersih perkotaan yang menggunakan air baku dari sungai, masalah yang sering dihadapi adalah pada proses penyisihan kekeruhan. Proses koagulasi flokulasi sebagai metode yang paling umum digunakan pada penyisihan TSS seringkalii mengalami permasalah pada efektifitas penggunaan bahan koagulan kimia yang berpengaruh terhadap pH serta gangguan kesehatan pada tingkat konsumsi yang lebih tinggi. Berdasarkan persamaan sifat dengan kitosan yang telah ditemukan sebagai koagulan alami yang efektif, tulang hewan sebagai sisa limbah konsumsi berpotensi menjadi alternatif baru sebagai koagulan alami. Penelitian ini menggunakan tiga jenis tulang hewan, yaitu tulang ayam, tulang sapi, dan tulang ikan. Pembuatan ekstrak tulang hewan dilakukan berdasarkan metode pembuatan kitosan, melalui 3 tahap yaitu deproteinasi, demineralisasi dan deasetilasi. Hasil penelitian menunjukkan hasil bahwa tulang hewan tidak mampu mendestabilisasi koloid dan membentuk flok. Berdasarkan uji FTIR, pada tulang hewan tidak ditemukan gugus amina yang memegang peranan penting dalam proses koagulasi dan flokulasi. ======================================================================================================================== The most complex problem in process of treating clean water in urban area is about turbidity removal. Coagulation flocculation is the most common method which is used to solve this problem. In the other hand, adding chemical coagulant in this process causes health problems in advance level and also give significant impact for pH level. Animal bones is a potential innovation as it has the similar characteristic as chitosan which is found as natural coagulant based on its active protein. This experiment is using three kind of animal bones; chicken bones, cow bones, and fish bones. Following the method of chitosan extraction, coagulant formation from animal bones are processed by three steps; deproteination, demineralization, and deasetilation. Based on te result of jartest analysis and also FTIR test, animal bones is not found as an effective coagulant. It’s caused by nonactive amina which has important function for flocs formation.
