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

In this product-based community service activity, the service team offers several concrete and tangible solutions to overcoming the problem of difficulties in obtaining ruminant feed. The solution offered is to build a portable silage machine tool system. The installation of this machine tool is an application of bioprocess technology where this equipment system is not only equipped with a biomass chopping machine but is also equipped with a biofermentor installation that can produce silage which is animal feed from fermented biomass rich in nutrients that are needed for increasing cow weight. Thus the equipment and machines designed can be a targeted solution in overcoming the shortage of animal feed for ruminant animal breeders in one of the assisted villages of Syiah Kuala University, namely Kayee Lee Village, and can also improve the skills and knowledge of farmers in producing animal feed independently and sustainable.

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.

Abstract

Purpose: This community service aims to apply anaerobic co-digestion technology to produce liquid organic fertilizer. Method: This anaerobic co-digestion technology is carried out by combining two substrates including animal manure and agricultural residues in one anaerobic reactor. In principle, an anaerobic reactor will decompose liquid waste from livestock waste and solid waste from agricultural processes. A mixture of livestock waste and agricultural process waste that has been processed in an anaerobic reactor will be able to produce organic fertilizer. Practical Applications: This technology is applied not only to produce bio-fertilizer but also to introduce waste management practice among farmers by controlling environmental pollution. The pollution is typically caused by neglected livestock waste and burning residues resulted from agricultural processes. Conclusion: This practice may effectively generate liquid organic fertilizers from processing agricultural wastes anaerobically, and also could significantly reduce the environmental pollution caused by agricultural processes.
