Abstract

Organic waste from coconut shells, corn cobs, candlenut shells, and lamtoro wood is often found in the Gorontalo region. The gasification of organic waste has the potential to reduce organic waste and produce gas for various applications, including heating, power generation, and industrial raw materials. The research aims to determine the gas composition of the downdraft gasification process from organic waste from coconut shells, candlenut shells, corn cobs, and lamtoro wood, to determine the rate of fuel consumption, and to determine the calorific value. The method used is an experimental method. Test results using a downdraft gasifier reactor with 5 kg of fuel. The average H2 value obtained from the test results for coconut shells was 12.46%, candlenut shells 13.01%, corn cobs 9.3%, and lamtoro wood 15.95%, the highest H2 value from several of these samples was obtained from lamtoro wood with the highest percentage was 15.95%, the average O2 value obtained was coconut shell 8.86%, candlenut shell 6.37%, corn cob 2.61%, lamtoro wood 5.22%, the average CH4 value was shell coconut 7.88%, candlenut shell 4.05%, corn cob 8.03%, lamtoro wood 7.32%, average CO value for coconut shell 0.56%, candlenut shell 0.05%, corn cob 10 .71%, lamtoro wood 0.05% while the average N2 value obtained was 70.21% coconut shell, 76.49% candlenut shell, 69.25% corn cob, and 71.44% lamtoro wood. The findings compare four organic wastes as alternative energy using a downdraft gasification reactor. The conclusion from this research is that the best gas composition is from corncob organic waste with H₂, CH₄, and CO of 28.05%, the longest burning rate on corncob samples is 23.11 grams/minute and the highest calorific value test is on lamtoro wood samples with results reaching 4,340 cal/gram.

Abstract

Pengelolaan sampah, khususnya sampah organik, menjadi tantangan serius di Indonesia, dengan sekitar 60-70% dari total sampah rumah tangga terdiri dari limbah organik. Pemanfaatan sampah organik sebagai sumber energi alternatif, melalui teknologi seperti biogas dan biodiesel, dapat mengurangi volume sampah dan ketergantungan pada bahan bakar fosil. Kegiatan sosialisasi yang dilaksanakan di Desa Suka Damai bertujuan meningkatkan kesadaran masyarakat tentang pengelolaan sampah organik dan penerapan teknologi sederhana seperti biodigester. Melalui workshop, demonstrasi, dan diskusi, peserta diajarkan cara mengolah sampah organik menjadi biogas. Evaluasi menunjukkan peningkatan pemahaman peserta dari 9% menjadi 92% setelah mengikuti kegiatan sosialisasi. Program ini diharapkan tidak hanya mengurangi dampak negatif lingkungan, tetapi juga meningkatkan kemandirian energi di tingkat lokal, serta memanfaatkan sumber daya yang tersedia secara melimpah, yaitu sampah organik. Waste management, especially organic waste, is a serious challenge in Indonesia, with around 60-70% of total household waste made up of organic waste. The use of organic waste as an alternative energy source, through technologies such as biogas and biodiesel, can reduce the volume of waste and dependence on fossil fuels. The socialization activities carried out in Suka Damai Village aim to increase public awareness about organic waste management and the application of simple technologies such as biodigesters. Through workshops, demonstrations, and discussions, participants were taught how to process organic waste into biogas. The evaluation showed an increase in participants' understanding from 9% to 92% after participating in socialization activities. This program is expected not only to reduce negative environmental impacts, but also to increase energy independence at the local level, as well as to utilize the abundant resources available, namely organic waste.

Abstract

Desa Bendungan adalah desa yang terletak di Kecamatan Mananggu dengan luas wilayah sebesar 89,84 km2, menjadikannya desa terluas di kecamatan tersebut. Observasi awal mendapati bahwa desa ini masih minim infrastruktur pengelolaan informasi, baik ke dalam maupun ke luar desa, walaupun desa ini memiliki akses internet yang cukup memadai. Pelaksanaan kegiatan KKN-MBKM ini bertujuan untuk mengembangkan sistem informasi desa sebagai Desa Digital dalam rangka mendorong pertumbuhan ekonomi lokal di desa Bendungan kecamatan Mananggu kabupaten Boalemo provinsi Gorontalo. Pengembangan sistem informasi dilakukan melalui penerapan metode Research and Development (RnD) dalam rekayasa perangkat lunak yang disesuaikan dengan pemenuhan kebutuhan dan solusi atas masalah yang ada. Berdasarkan hasil evaluasi kegiatan yang dilakukan melalui kuesioner kepuasan layanan desa sebelum dan setelah adanya sistem informasi desa, terjadi peningkatan tingkat kepuasan masyarakat terhadap layanan desa, yakni tingkat kepuasan layanan desa dari 8% menjadi 45%, tingkat kemudahan akses layanan dari 3% menjadi 95%, dan tingkat kemudahan akses informasi dari 3% menjadi 98%.
