Abstract

Bank sampah saat ini telah menjadi salah satu solusi pemerintah untuk menangani sampah di perkotaan. Beberapa bank sampah bahkan telah memiliki cabang untuk memperluas jangkauan pelayanan. Cabang bank sampah tersebut sering disebut sebagai bank sampah unit. Kajian ini bertujuan untuk mengetahui sistem operasional bank sampah unit dalam membantu pengelolaan sampah perkotaan dan hubungannya dengan bank sampah induk. Metode yang digunakan dalam kajian ini adalah observasi langsung di salah satu kota yang memiliki bank sampah induk serta kajian literatur, kemudian dianalisis secara deskriptif. Hasil observasi dan penelaahan diperoleh bahwa ikatan bisnis antara bank sampah induk dan unit tidak rumit. Bank sampah induk memberikan cara dan prosedur transaksi di bank sampah unit beserta harga penukaran sampah. Jenis unit antara lain bank sampah perkantoran, sekolah, dan warga. Walaupun terdapat standar operasi yang ditetapkan oleh bank sampah induk, namun tiap unit memiliki praktek operasional yang disesuaikan dengan kondisi masing-masing unit, antara lain untuk sistem pemilahan, penyimpanan, penyerahan ke bank sampah induk dan jam operasi.

Abstract

River water quality modeling needs appropriate and suitable coefficients especially in application for specific river like urban river. Aim: This study aims to determine the value of the coefficient with a short term duration and a variable test time span.  Several ways and methods of determining the rate of deoxygenation are developed according to the characteristics of the river and the environment. Modification method was applied in this research in which the test time span was unequal. The river chosen in this study is the Citepus River, Bandung, Indonesia representing an urban river in a tropical country. Methodology and Results: Sampling was carried out in the dry season. The laboratory analysis method used in determining the rate of deoxygenation uses the Slope Method of data from the short term incubation, which is ten days. The results showed that the Thomas Slope method's deoxygenation rate (K1) was 0.095 per day in the upstream segment, 0.917 per day in the middle segment, and 0.180 per day in the downstream segment. While the Ultimate BOD (La) value is 46.95 mg/l in the upstream segment, 38.70 mg/l in the middle segment, and 37.60 mg/l in the downstream segment. Conclusion, significance, and impact of study: The results of this study show that the value of the deoxygenation rate is similar to the theoretical surface water conditions. However, in the upstream segment, there is still a low deoxygenation rate value due to non-optimal activity of microorganisms. This findings will be very useful both in water quality modeling and river management.
