STUDI PERENCANAAN INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) KOMUNAL PADA PONDOK PESANTREN SALAFIYAH SYAFI’IYAH KABUPATEN SITUBONDO

Abstract

The Salafiyah Syafi'iyah Islamic Boarding School is located in Sukorejo village, Banyuputih District, Situbondo Regency, which has an area of ± 11.9 ha. The Salafiyah Syafi'iyah Islamic Boarding School consists of tens of thousands of students who have a high need for water and produce quite a bit of waste water. For the continuity of the students' activities, one of the things that must be considered is adequate sanitation facilities to prevent the potential for environmental pollution and health problems. Domestic wastewater at the Salafiyah Syafi'iyah Islamic Boarding School comes from the toilet, shower, ablution area, clothes washing area and kitchen. It is directly channeled into water bodies without prior processing. The problem of domestic wastewater becomes very serious due to the discharge of domestic wastewater directly into the environment through drainage channels which ultimately flows into rivers without being treated first. Based on the findings of the observations that have been made, the Salafiyah Syafi'iyah Islamic Boarding School disposes of greywater directly onto the ground or into nearby channels (rivers, ditches or ditches) without further processing. The Salafiyah Syafi'iyah Islamic Boarding School has a total of 4,140 students. ABR (Anaerobic Baffled Reactor) technology will be used for the planned greywater wastewater treatment. This technology was chosen because of its ease of operation, as well as technical and financial considerations and land availability. From the planning it is known that the waste water quality of BOD 11.33 mg/l, COD 46.36 mg/l, and TSS 57.8 mg/l, meets quality standards. The average BOD, COD, and TSS used in planning were 8 mg/L, 33.408 mg/L, and 23.1mg/L, respectively.

Pondok Pesantren Salafiyah Syafi’iyah memiliki jumlah santri sebanyak 4.140 jiwa. Teknologi ABR (Anaerobic Baffled Reactor) akan digunakan untuk pengolahan air limbah greywater yang direncanakan. Teknologi ini dipilih karena kemudahan pengoperasiannya, serta pertimbangan teknis dan finansial serta ketersediaan lahan. Dari perencanaan diketahui bahwa kualitas air limbah BOD 11,33 mg/l, COD 46,36 mg/l, dan TSS 57,8 mg/l, memenuhi baku mutu. Rata-rata BOD, COD, dan TSS yang digunakan dalam perencanaan masing-masing adalah 8 mg/L, 33,408 mg/L, dan 23,1mg/L.
