Abstract

Kualitas air tambak menjadi menurun akibat penumpukan kotoran udang, aktivitas bakteri, ganggang, dan lain-lain, sementara penggantian air baru juga memiliki risiko yang tinggi dengan tingginya kemungkinan masuknya virus berbahaya ke dalam tambak. Salah satu cara untuk menjaga kualitas air tambak adalah dengan melakukan aerasi secara teratur. Ketersediaan listrik menjadi kendala untuk areal tambak udang di Desa Alue Kumba akibat belum terkoneksinya jaringan listrik PLN. Penelitian ini dilakukan untuk mengkaji efektivitas kincir angin sebagai solusi penyediaan oksigen terlarut pada tambak udang tradisional di Desa Alue Kumba serta dapat menjaga kualitas air selama pemeliharaan udang yang dapat berujung pada peningkatan produktivitas tambak. Perlakuan yang diterapkan merupakan kombinasi konstruksi kincir angin dan air tambak dengan sistem kecepatan angin oleh turbin savonius yang ditimbulkan untuk menggerakkan bagian kipas yang memunculkan tenaga pembangkit gelembung pada kolam tanah (tambak). Hasil kombinasi kincir yang dilakukan efektif dalam menghasilkan oksigen terlarut dalam tambak tradisional di Desa Alue Kumba Kecamatan Rantau Selamat Kabupaten Aceh Timur.

Abstract

Biodiesel is produced by esterification-transesterification, using alcohol as a reactant and acid and base catalysts. Electrocatalyst is a method to increase production yield by utilizing H+ and OH– ions as a catalyst. This study aims to investigate the biodiesel production process through the esterification-transesterification reaction and analyze the physicochemistry of biodiesel produced from CPO by electrolysis using platinum electrodes. CPO was esterified-transesterified and then analyzed the production yield and physicochemistry of biodiesel. Rsults showed that the highest biodiesel yield was produced at a voltage of 6 V, which is 88.67%, the lowest acid value and moisture content of biodiesel was produced from a voltage of 12 V are 0.99 mgKOH/g and 0.75%, the kinematic viscosity that met the SNI biodiesel standards resulted in a voltage of 6 V and without the use of electrolysis, namely 3.53 cSt and 3.63 cSt, and the highest flash point value for biodiesel is produced from a voltage of 12 V, which is 109 ° C.   Keywords:  Biodiesel, Crude palm oil (CPO), Electrolysis, Physicochemical, Platinum.

Abstract

Purpose: This research paper explores an integrated solution for managing tofu waste from the SOLO Tofu Factory. By combining anaerobic digestion technology with urban organic farming, the study aims to provide a sustainable waste management model that benefits the factory and the surrounding community. Method: The study utilized mixed methods, including qualitative interviews and quantitative on-site observations. Anaerobic digestion technology was employed for waste treatment, and its effluent was analyzed for its potential as a bio-fertilizer. A sustainable urban organic farming system was developed, utilizing treated waste for cultivation. Data analysis involved qualitative thematic and quantitative measurement analysis. Practical Applications: The integrated approach offers helpful solutions. It provides the factory with an eco-friendly waste management solution, reducing pollution. The urban organic farming system promotes sustainable agriculture and remediates land, making it cultivable. This model serves as a blueprint for similar industries, fostering community development and environmental awareness. Conclusion: The research demonstrates the effectiveness of integrating anaerobic digestion and urban organic farming for tofu waste management. This approach offers practical, scalable solutions, reducing pollution, promoting sustainable agriculture, and fostering community development.
