Abstract

Sanitasi adalah salah satu masalah yang masih dihadapi oleh Indonesia, termasuk penggunaan tangki septik dan pengolahan lumpur tinja. 83% tangki septik yang beroperasi di Indonesia bocor dan tidak sehat akibat kurangnya pengontrolan dan perawatan tangki septik oleh masyarakat pengguna maupun petugas pemerintah. Terdapat produk alternatif yang beredar di kalangan masyarakat dalam bentuk cairan bio-starter yang digunakan untuk membantu mendegradasi lumpur tinja dalam tangki septik. Bio HS (Higienis Super) mengandung mikroba enzimatis yang dapat mempercepat degradasi lumpur tinja dalam tangki septik. Mikroorganisme yang terdapat dalam Bio HS antara lain mikrobakteri lipolitik, amilolitik, proteolitik, selulolitik, serta lignolitik. Penambahan Bio HS bermaksud untuk meningkatkan jumlah mikroorganisme dan mempercepat penguraian. Bio HS diharapkan bisa memperpanjang masa pengurasan. Penelitian bertujuan untuk menganalisis pengaruh Bio HS pada lumpur tinja dan menentukan dosis optimal untuk penyisihan paling baik. Penelitian skala laboratorium ini dilakukan dengan menggunakan reaktor batch. Setiap reaktor diisi dengan lumpur tinja sebanyak 1200 mL dalam reaktor 1300 mL. Penelitian dilakukan dalam waktu 2 (dua) bulan. Terdapat 5 (lima) variasi perlakuan yaitu 0,6 mL Bio HS atau 0,05% v/v; 2,4 mL Bio HS atau 0,2% v/v dan 4,8 mL Bio HS atau 0.4% v/v serta penambahan media pada dosis 0.05% v/v. Parameter yang dianalisis meliputi TSS, BOD, COD, volume lumpur dan supernatan dalam reaktor, serta pH dan Temperatur. Hasil penelitian menunjukkan bahwa sampel dengan penambahan 0,05% v/v Bio HS dapat mendegradasikan lumpur paling optimal pada hari ke-42 dengan penyisihan rbCOD, COD, BOD, dan TSS masing-masing sebesar 100%, 89%, 89%, dan 45%. Sedangkan untuk sampel Bio HS 0,2% v/v penyisihan rbCOD, COD, BOD, dan TSS masing-masing sebesar 89,5%, 83,2%, 75,3%, sedangkan TSS tidak megalami penyisihan. Sampel Bio HS 0,4% v/v memiliki penyisihan penyisihan rbCOD, COD, BOD, dan TSS masing-masing sebesar 93,8%, 82,1%, 66,9%, dan tidak terdapat penyisihan untuk parameter TSS. Hasil menunjukan bahwa semua perlakuan terjadi pada rentang pH optimum (6,5 – 8,0) dan temperature dalam rentang 28-33oC. Pemisahan antara lumpur dan supernatan terbaik baru terlihat pada hari ke-35 di sampel Bio HS 0,05% v/v. ================================================================================================== Sanitation is one of the problems still faced by Indonesia, including the use of septic tanks and the treatment of sludge. 83% of septic tanks operating in Indonesia are leaking and unsanitary due to lack of control and maintenance of septic tanks by community users and government officials. There is an alternative product circulating among the community in the form of a bio-starter liquid which is used to help degrade sludge in septic tanks. Bio HS (Higienis Super) contains enzymatic microbes which can accelerate the degradation of sludge in septic tanks. Microorganisms contained in Bio HS include lipolytic, amylolitic, proteolytic, cellulolitic, and lignolytic. The addition of Bio HS intends to increase the number of microorganisms and accelerate decomposition. Bio HS is expected to extend the draining period. The research aims to analyze the influence of Bio HS on fecal sludge and determine the optimal dose for the best penyisihan. This laboratory-scale research was conducted using batch reaktors. Each reaktor is filled with 1200 mL of fecal sludge in a 1300 mL reaktor. The research was conducted within 2 (two) months. There are 5 (five) treatment variations of 0.6 mL Bio HS or 0.05% v/v; 2.4 mL Bio HS or 0.2% v/v and 4.8 mL Bio HS or 0.4% v/v as well as media addition at a dose of 0.05% v/v. The analysis looked at BOD, COD, rbCOD, VSS, and TSS levels. Parameters analyzed included TSS, BOD, COD, sludge volume and supernatant in reaktor, pH and temperature. The results show that samples with the addition of 0.05% v/v Bio HS were able to degrade the most optimal sludge on the 42nd day with rbCOD, COD, BOD, and TSS removal of 100%, 89%, 89%, and 45%, respectively. As for Bio HS 0.2% v/v removal of rbCOD, COD, BOD, and TSS respectively by 89.5%, 83.2%, 75.3%, while TSS has no removal. Bio HS 0.4% v/v samples have rbCOD, COD, BOD, and TSS removal of 93.8%, 82.1%, 66.9%, and no removal for TSS parameters, respectively. Results showed that all treatments occurred in the optimum pH range (6.5 – 8.0) and temperatures in the 28-33oC range. The separation between the mud and supernatant was only seen on day 35 in the Bio HS 0.05% v/v sample.
