Abstract

AbstrakPemenuhan ketersediaan air untuk menunjang proses produksi pada perusahaan sangatlah penting. Pada umumnya perusahaan untuk memenuhi ketersediaan air mengguankan suplai dari pihak PDAM. Namun kuantitas yang berasal dari pihak PDAM masih kurang untuk memenuhi kebutuhan proses produksi. Dengan permasahaan yang ada mengenai kekurangan air dan demi menjaga kuantitas ketersediaan air bersih maka perusahaan ini melakukan recycle hasil efluen IPAL menjadi air minum. Pengolahan yang dilakukan yaitu menggunakan teknologi reverse osmosis. Penelitian ini dilakukan dnegan tujuan mengetahui proses recycle air limbah menggunakan teknologi RO dan mendapatkan efisiensi biaya air bersih di perusahaan dengan membandingkan antara biaya operasional RO dan biaya operasional pembelian air bersih dari pihak PDAM. Diperoleh hasil bahwa pengolahan efluen IPAL dapat di recycle menjadi air minum dengan teknologi RO. Parameter yang dihasilkan oleh hasil teknologi ini juga telah memenuhi standar baku mutu Peraturan Menteri Kesehatan Nomor: 492/MENKES/Per/IV/2010. Unit yang digunakan pada pengolahan ini yaitu sistem DAF dengan penambahan koagulan PAC, sand filter,  carbon filter, ultrafiltration, dan reverse osmosis. Perhitungan efisiensi biaya setiap m3 air yang diperoleh dari pengolahan teknologi reverse osmosis dan suplai dari PDAM pada 5 bulan terakhir dapat mencapai rata-rata Rp78.503.990,47.Kata Kunci : Reverse Osmosis, Air Minum, Efisiensi.

Abstract

UPN "Veteran" Jawa Timur is one of the campuses in East Java. Various types of waste are produced on campus, including organic waste (used rice, used vegetables, tree branches, leaves, etc.) as well as inorganic waste, one of which is medical mask waste. The existence of these wastes will increase along with increasing human growth, in this case, student enrollment on campus. Therefore, waste processing must be carried out to reduce the generation and impacts that will result. One alternative for processing waste is recycling it into products with high selling value. This community service aims to show that the waste produced can be made into products that have high selling value such as soap from used cooking oil, maggots for fish food, local microorganisms, trash cans from used masks, pots from used masks, candles aromatherapy from used cooking oil and tumbler bottles to reduce use plastic bottles and compost. The method used in community service activities carried out at the UPN "Veteran" Jawa Timur campus is to create solutions for managing the waste produced to solve existing problems. The solution is in the form of creating entrepreneurial products as mentioned previously. The result of this community service has been running smoothly and well. The products made have high selling value. This is proven by the entrepreneurial activities that have been carried out showing that these products are in demand by the public.
