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.

Abstract

This research was conducted to test the reliability of the performance of the OCR-GFR relay whether it complies with the settings or not during field testing and to find out a comparative analysis of the performance of theoretical calculations with the results of field testing using the CMC 356 test equipment. This research uses a descriptive method. This research aims to determine whether the performance of the OCR–GFR relay that is being used is still good performance or suitable for use. And the tests carried out are pick up and drop off tests and characteristic tests. The results of the OCR pick-up and drop-off relay test were 1.2 A and the drop-off was 1.134 A. Meanwhile, for the GFR relay the pickup relay was 0.20 A and the drop-off was 185.0 mA. The results of the pickup and drop-off tests can conclude that the relay works according to its settings. Meanwhile, for field testing, the OCR relay characteristics at 1.5 times the setting current are 3.627 s and the theoretical calculation results are 3.697 s. For the GFR relay, the field test results obtained were 1.5 times the setting current, namely 1.981 s, and the theoretical calculation results were 1.977 s. This means that the test results are close to the calculated values. This shows that the Micom P142 OCR/GFR Relay tested is still in good performance.

Abstract

The windling availability of fossil fuels and the continuosuly increasing demand from them cause an imbalance in the stability of demand and supply. One of the efforts that can be made to replace fossil fuels is to utilize biomass energy, such as bioethanol, as substitute for fossil fuels. This study aims to determine the process of making bioethanol from banana peel by adding several variations in the composition of tape and bread yeast. Moveover, it also aims rto determine the composition of biethanol that meets the Indonesian National Standasd (SNI) 7390:2012 by conducting experiments ti determine the ethanol content, methanol content, water content, density, and viscosity. The result of the study show the best quality that can be used as a fuel substitute is the result of fermentation using 10% tape yeast from banana peel, with an ethanol content of 95.56%, methanol content of 0,52%, water content of 0,86%, density of 0,783 gr/ml, and viscosity of 1,17cP.

Abstract

Various methods have been taken to optimize the availability of fossil bioenergy reserves in Indonesia but have not been able to meet primary energy needs. The continued use of fossil- based energy such as oil, natural gas and coal will have an impact on increasing greenhouse gas emissions and climate stability. The bioenergy potential of biomass sources encourages researchers to conduct research on biomass waste as an alternative energy source. This research was conducted to determine the calorific value, combustion rate and water content of cocoa shell and candlenut shell waste using a mixture of different composition variations. The method used in this research is an experimental method to determine the heat value using a bomb calorimeter, and to determine the combustion rate using a mini gas stove. In the research results, the calorific value contained in sample 9 with variations of 200 grams of candlenut shells, 10 grams of sago flour has a calorific value of 5213.7 cal/gram. The longest burning rate was found in sample 8 with a mixture of 200 grams of candlenut charcoal and 10 grams of tapioca adhesive. Produces 0.203 grams/minute. The water content values in samples with different composition variations obtained results that were far from the SNI 01-6235-200 standard. This was influenced by the pressing pressure being applied not being strong enough and the pressure time being too fast. Other factors are influenced by air temperature and humidit.

Abstract

Desa Rumbia di Kecamatan Botumoito, Kabupaten Boalemo, merupakan sebuah Desa Swadaya yang memiliki potensi alam cukup signifikan dalam bidang pengelolaan sumber air bersih. Selain itu, Desa Rumbia juga berpotensi menjadi pusat peternakan terbesar di wilayah tersebut. Namun, fasilitas pengelolaan sampah di desa tersebut masih kurang baik karena tidak memiliki Tempat Pembuangan Sementara (TPS). Hal ini menjadi salah satu persoalan serius yang dihadapi oleh masyarakat Desa Rumbia. Oleh karena itu, masyarakat Desa Rumbia perlu memiliki aternatif pengelolaan sampah supaya lingkungan tetap terjaga. Berangkat dari masalah ini, tim pengabdian melakukan penyuluhan tentang pemanfaatan sampah organik menjadi biogas. Upaya ini dapat menjadi bentuk pengoptimalan sumber energi alternatif guna mengatasi persoalan sampah di Desa Rumbia. Tujuan pengabdian ini adalah memberikan pengetahuan kepada masyarakat tentang teknologi biogas dan pemanfaatan sampah organik sebagai bahan baku reaktor biogas. Metode pengabdian berupa penyuluhan melalui pendekatan ceramah agar masyarakat lebih paham cara mengolah sampah dengan mengubah sampah organik menjadi biogas. Untuk mengevaluasi efektivitas kegiatan, dilakukan uji pra dan pasca penyuluhan. Evaluasi hasil uji pra dan pasca dilakukan dengan pendekatan deskriptif kuantitatif. Berdasarkan hasil evaluasi, pelaksanaan penyuluhan teknologi biogas di Desa Rumbia telah sukses dilakukan. Hal ini terbukti dari hasil post-tes yang menunjukkan peningkatan pengetahuan peserta mengenai reaktor biogas dari sebelumnya 4% menjadi 90,67%.
