Abstract

Waste from the tofu industry is a byproduct of the tofu production process that can have negative environmental impacts if not managed properly. CV. Dapur Tahu still discharges liquid waste directly into the river, posing a potential threat of river water pollution. Although a new reservoir and waste disposal channel are under construction, there is currently no effective waste treatment facility in place. To address this issue, a tofu wastewater treatment facility utilizing filtration technology is proposed due to its simplicity of operation, durability, and high efficiency in removing organic contaminants. The technology comprises a multi-stage filtration process involving sand filters (pumice, zeolite, and activated charcoal) combined with ultrafiltration membrane technology, complemented by a monitoring system consisting of TDS, pH, and temperature sensors. The multi-stage filtration process is capable of reducing TDS levels to 160 ppm, resulting in visibly clearer wastewater compared to the initial turbid white condition. The installation of IoT-based monitoring devices in the wastewater treatment process significantly aids in real-time water quality monitoring, accessible via mobile phone screens.

Abstract

Banyaknya jumlah peternak sapi di Indonesia memiliki pro dan kontra. Limbah ternak, terutama kotoran, merupakan hal yang biasa dihasilkan dari peternakan sapi. Pengelolaan kotoran sapi yang buruk menyebabkan bau, kontaminasi air, dan pertumbuhan mikroba berbahaya. Biogas dari kotoran sapi dapat digunakan untuk menghasilkan energi alternatif. Biogas dari biodigester tradisional biasanya tidak dimurnikan. Sebuah biodigester terintegrasi sederhana dengan perangkat pemurnian atau penyerap dapat menghilangkan polutan dari biogas. Alat pemurni/adsorber sirkuit biodigester menghilangkan kontaminan biogas tanpa peralatan terpisah. Penelitian ini menggunakan metode eksperimen dengan percobaan produksi biogas dan penyerapan gas H2S dengan dua kali percobaan. Hasil penelitian menunjukkan bahwa perancangan alat biodigester ini memiliki hasil penyerapan yang baik dan menunjukkan kadar H2S sesuai sesuai dengan standar mutu biogas SNI 8019:2014.
