Abstract
Limbah cair industri pengolahan porang termasuk ke dalam golongan limbah cair pengolahan sayur dan buah. Selain mengandung polutan organik, limbah cair industri pengolahan porang juga mengandung kalsium oksalat yang cukup tinggi. Senyawa organik dan kalsium oksalat yang terkandung di dalam limbah cair porang dapat menyebabkan pencemaran lingkungan apabila tidak diolah dengan baik. Oleh karena itu dilakukan penelitian ini dengan tujuan untuk membuat rancangan prototipe pengolah limbah cair industri pengolahan porang serta menguji tingkat performansi kinerja prototipe pengolah limbah cair dalam mereduksi kalsium oksalat, TSS, BOD, dan COD pada limbah cair industri pengolahan porang. Penelitian dilakukan dengan beberapa tahapan meliputi studi pustaka, perancangan prototipe, pembuatan prototipe, evaluasi dan pengujian prototipe. Pengolahan limbah cair industri pengolahan porang menggunakan 3 macam metode yaitu filtrasi, elektrokoagulasi, dan ozonisasi. Filtrasi limbah cair menggunakan jaring-jaring filter dengan 3 tingkatan ukuran. Proses elektrokoagulasi memanfaatkan anoda dan katoda yang terbuat dari stainless steel. Sebelum memasuki proses ozonisaasi, flok-flok yang terbentuk pada proses elektrokoagulasi akan difiltrasi menggunakan saringan kain. Proses selanjutnya adalah proses ozonisasi dengan memanfaatkan ozon (O3). Prototipe juga dilengkapi dengan sensor pH, TDS, dan kekeruhan yang dihubungkan dengan sistem Internet of Things (IoT) atau sistem kontrol jarak jauh. Berdasarkan hasil uji didapatkan bahwa prototipe ini terbukti mampu mengurangi kadar kalsium oksalat sebesar 19%, kadar TSS sebesar 94%, meningkatkan nilai pH hingga 19%, mengurangi kadar BOD sebesar 53,35%, dan mengurangi kadar COD sebesar 64,52%.
English Abstract
Wastewater from the porang processing industry is included in the category of wastewater from vegetable and fruit processing. Apart from containing organic pollutants, Wastewater from the porang processing industry also contains quite high amounts of calcium oxalate. The organic compounds and calcium oxalate contained in porang wastewater can cause environmental pollution if not processed properly. Therefore, this research was carried out to design a prototype wastewater processor for the porang processing industry and test the performance level of the wastewater processing prototype in reducing calcium oxalate, TSS, BOD, and COD in wastewater from the porang processing industry. The research was carried out in several stages including literature study, prototype design, prototype creation, prototype evaluation, and testing. Processing wastewater from the porang processing industry uses three types of methods such as filtration, electrocoagulation, and ozonation. Filtration process uses filter nets with 3 size levels. The electrocoagulation process utilizes an anode and cathode made of stainless steel. Before entering the ozonation process, the flocs formed in the electrocoagulation process will be filtered using a cloth filter. The next process is the ozonation process using ozone (O3). The prototype is also equipped with pH, TDS, and turbidity sensors connected to remote control system. Based on the test results, it was found that this prototype was proven to be able to reduce calcium oxalate up to 19%, reduce TSS up to 94%, increase pH up to 19%, reduce BOD up to 53.35%, and reduce COD up to 64.52%.
