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

Increasing infrastructure through the allocation of village funds in the context of improving community services is increasingly being carried out in every region. Every year the allocation of village funds through the APBN continues to increase. Along with these efforts, village officials who are expected to be intermediaries for the implementation of the infrastructure improvement program are required to have the ability to carry out technical development implementation activities in the field. Tongo Village as a partner who cooperates in Community Service activities this time has been guided and trained through training activities using the learning by doing method related to Work Unit Price Analysis (AHSP) based on the Indonesian National Standard (SNI). The materials provided to village officials are: an introduction to the RAB and its constituent components, and Work Unit Price Analysis (AHSP) which consists of: work volume, estimated time for work completion, calculation of the number of workers and material requirements. From the results of the training it can be concluded that village officials understand how to make a Work Unit Price Analysis (AHSP) according to the Indonesian National Standard (SNI) using Microsoft Excel as the main component in the Budget Plan (RAB).

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%.

Abstract

ABSTRAKPasar tradisional masih menjadi salah satu faktor penggerak ekonomi masyarakat di tengah-tengah maraknya sistem jual-beli online, tumbuhnya pasar modern, dan juga gerai waralaba. Penelitian ini dilakukan dalam rangka solusi penanganan masalah sampah organik yang dihasilkan dari transaksi jual-beli di pasar tradisional. Pendekatan yang dilakukan adalah memanfaatkan sampah organik sebagai sumber energi alternatif melalui proses fermentasi untuk menghasilkan gas metan. Metodologi gabungan (mix methode) digunakan dalam penelitian ini yakni pendekatan kuantitatif melalui pengukuran langsung di lapangan berdasarkan SNI Persampahan 19-3964-1994 dan pendekatan kualitatif digunakan untuk menganalisis kelayakan potensi sampah organik berdasarkan data kuantitatif. Hasil Penelitian didapatkan bahwa persentase timbulan sampah organik Pasar Sentral Kota Gorontalo adalah 74,23% sampah sayuran, 17,12% sampah buah dan 8,65% sampah ikan/daging yang dapat menghasilkan Biogas sebesar 838,60 m3 per bulan yang setara dengan energi listrik sebesar 5.115,84 kwh per bulan.Kata kunci: biogas, energi terbarukan, potensi, sampah pasar ABSTRACTTraditional markets are still one of the factors driving the community's economy in the midst of the rise of online buying and selling systems, the growth of modern markets, and franchise outlets. This research was conducted in order to solve the problem of handling organic waste generated from buying and selling transactions in traditional markets. The approach taken is to utilize organic waste as an alternative energy source through a fermentation process to produce methane gas. The combined methodology (mix method) used in this research is a quantitative approach through direct measurements in the field based on SNI for Solid Waste 19-3964-1994 and a qualitative approach is used to analyze the feasibility of potential organic waste based on quantitative data. The results showed that the percentage of organic waste generated at the Central Market of Gorontalo City is 74.23% vegetable waste, 17.12% fruit waste and 8.65% fish/meat waste which can produce 838.60 m3 of biogas per month which is equivalent to energy. electricity of 5,115.84 kwh per month.

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.
