Abstract

Water is one of the "elements of nature" which are the basic necessities of human life. Nowadays, the need for water for industrial processes is important, from this air requirement there must be wastewater treatment that is truly in line with the surrounding environmental conditions. Home industry wastewater treatment processes have the potential existence of environmental pollution, for example tempe liquid waste in certain concentrations can be negative waste to the environment, especially for human health needs to be treated against waste. Based on the Minister of Environment Regulation No. 5 of 2014 concerning Wastewater Quality Standards, food industry wastes included in the Domestic Wastewater consist of BOD, TSS, pH, Oil and Fat parameters. Tempe food wastewater treatment concept is quite minimal processing. Therefore an electrocoagulation system is designed to optimize water treatment to comply with ministerial regulations. The principle of electrocoagulation process based on electrolysis cells using two electrodes is given a voltage which is placed in one place which is controlled by fuzzy logic. From the results of testing on tempe wastewater using an electrocoagulation system with a fuzzy method, it can provide optimal results. Wastewater carried out by the electrocoagulation process results in changes in levels and temperature, nutrient levels have an initial value of 3720 ppm, rising to 3022 ppm. Acidity has an initial value of 2.56pH, rising to 6.12 pH. And the initial temperature has a value of 30.06 ºC, rising to 51.18 ºC. Keywords: Electrocoagulation, FIS Sugeno , Nutrition, pH, Temperature Air merupakan salah satu “Unsur alam” yang menjadi kebutuhan dasar bagi kehidupan manusia. Dewasa ini, kebutuhan air untuk keperluan proses industri sangatlah penting, dari keperluan air tersebut harus ada pengolahan air limbah yang benar terhadap kondisi lingkungan di sekitarnya. Proses pengolahan air limbah home industry pangan memiliki potensi adanya pencemaran lingkungan, contohnya limbah cair tempe dalam konsentrasi tertentu kehadiran limbah dapat berdampak negatif terhadap lingkungan terutama bagi kesehatan manusia sehingga perlu adanya penanganan terhadap limbah. Berdasarkan peraturan Menteri Lingkungan Hidup Nomor 5 tahun 2014 tentang Baku Mutu Air Limbah, bahwa limbah industri pangan tempe termasuk dalam Air Limbah Domestik terdiri dari parameter BOD, TSS, pH, Minyak dan Lemak. Pengolahan air limbah pangan tempe konsep pengolahanya cukup minim. Maka dari itu dirancang sebuah sistem elektrokoagulasi yang dapat mengoptimalkan pengolahan air limbah agar sesuai dengan peraturan menteri. Proses elektrokoagulasi prinsipnya berdasarkan sel-elektrolisis menggunakan dua elektroda di berikan tegangan yang di tempatkan pada satu tempat yang di kendalikan dengan fuzzy logic. Dari hasil pengujian pada air limbah tempe menggunakan system elektrokoagulasi dengan metode fuzzy, dapat memberikan hasil yang cukup optimal. Air limbah yang dilakukan proses elektrokoagulasi menghasilkan perubahan kadar dan suhu, Kadar nutrisi memiliki nilai awal 3720 ppm, turun menjadi 3022 ppm. Kadar keasaman memiliki nilai awal 2,56pH, naik menjadi 6,12 pH. Dan suhu awal memiliki nilai 30,06 ºC, naik menjadi 51.18 ºC. Kata Kunci : Elektrokoagulasi, Nutrisi, pH, Suhu, FIS Sugeno
