Karakteristik Air Limbah Industri Tempe (Studi Kasus: Industri Tempe Semanan, Jakarta Barat)

Abstract

Tempe is one of the traditional Indonesian foods that have liked by people for a long time. In the tempe processing process, besides soybeans, water is also one of the raw materials that has an important role because water is used in almost every production process: Boiling, Soaking, Washing, and Fermenting. To process 1 kg of soybeans into tempe requires 24.28 liters of water where the boiling process requires 7.02 liters of water, 4.36 liters of soaking, 7.64 liters of washing, and fermentation requires 5.26 liters of water. Tempe production also produces waste water that is bad for the environment where in all the water used in the production process is directly disposed of without being processed first. The quality standard for tempe processed waste is regulated in the Regulation of the Minister of the Environment of the Republic of Indonesia No. 5 of 2014 with 3 main parameters, namely BOD with levels of 150 mg/l, COD 300 mg/l, TSS 100 mg/l. Wastewater produced by tempe production contains BOD 4146.50 mg/l, COD 32297.71 mg/l, and TSS 0.75 mg/l. The wastewater produced by tempe production exceeds the government quality standard, but in the production of tempe, the waste water is not treated but is discharged into water bodies.

Pengolahan Limbah Cair Industri Tempe Menggunakan Metode Moving Bed Biofilm Reactor (MBBR) Dan Metode Filtrasi

“…Berdasarkan Peraturan Menteri Lingkungan Hidup Republik Indonesia No.5 Tahun 2014 Tentang Baku Mutu Air Limbah, Baku Mutu Air Limbah Bagi Usaha Dan/Atau Kegiatan Pengolahan Kedelai, TSS yaitu zat yang tidak dapat terpisah dari cairan yang berada didalam air dengan ukuran > 1µm dan saling berkesinambungan dengan tingkat kekeruhan. Baku mutu TSS yang ditetapkan yaitu 100 mg/L (Pakpahan et al, 2021).…”

Effluent Quality Monitoring in Industrial Waste Water Treatment at PT. X

“…BOD (Biological Oxygen Demand) is the value of the amount of dissolved oxygen needed by microorganisms to decompose or oxidize organic matter in the waste water. The BOD value does not indicate the quantity of organic matter but only measures the oxygen needed to perform oxidation [4]. The average influent value in 2022 is 36.2 mg/L.…”

Ampas Bubuk Kopi sebagai Karbon Aktif untuk Menurunkan Kadar COD dan TSS dalam Limbah Cair Industri Tempe

“…Industri tempe adalah industri yang mudah ditemui di Indonesia, karena tempe telah menjadi makanan tradisional yang popular dan digemari oleh masyarakat Indonesia selama bertahun-tahun. Dalam proses pembuatan tempe, air memiliki peran penting dan digunakan dalam hampir setiap tahap produksi, seperti perebusan, perendaman, pencucian, dan peragian [4]. Namun, industri tempe juga menghasilkan limbah cair yang mengandung polutan berbahaya bagi lingkungan, seperti COD, BOD, dan TSS.…”

“…Namun, industri tempe juga menghasilkan limbah cair yang mengandung polutan berbahaya bagi lingkungan, seperti COD, BOD, dan TSS. Sayangnya, limbah ini seringkali dibuang begitu saja tanpa melalui proses pengolahan yang memadai [4]. Baku mutu limbah hasil pengolahan tempe diatur oleh peraturan lingkungan Republik Indonesia, yang mengharuskan kadar BOD, COD, dan TSS dalam limbah mencapai tingkat tertentu.…”
