Abstract

Mini-hydro Power Plant (PLTM) is one of the hydroelectric power plants of choice where PLTM utilizes water energy which has a flow capacity that is not too large. The Padang Guci PLTM with a capacity of 3x2 MW is located in the Air Padang Guci River, under the auspices of PT. Sahung Brantas Energi in collaboration with the Kaur district government to improve electrical energy services to the community. The electrical energy produced by the Padang Guci PLTM is highly dependent on the flow capacity of the Padang Guci river. The data collection process is carried out to retrieve data about voltage, current, time, and electricity production generated by the generator. The electricity produced by the generator can be seen in kWh in the control room. Data on electricity production, current, and voltage on the kWh meter are then inputted into the computer in the operator's room. Every half hour the data is recorded in the table, the daily data table will be entered into excel and will be inputted into the monthly data. Total electricity production during July 2021 is 1,444,252 kWh and the average daily electricity production is 46,588.77 kWh. With the highest daily electricity production, which is 77,644 kWh, the main cause of the increase in electricity production is due to rain which causes flooding in the river flow so that the turbine operates optimally, because the flow rate required is sufficient to power the three turbines to a maximum of 2 MW. Then for the lowest electricity production, which is 5,124 kWh, due to trips and less flow rate.

Abstract

Energy is an important part of human life because almost all human activities always require energy. Therefore, it is necessary to conduct research to overcome the above problems, namely by making alternative energy by utilizing crumb rubber plant waste into alternative oil. The crumb rubber solid waste that we use comes from the micro blending and macro blending milling process from the process there is waste in the form of granulated rubber (Crumb Rubber Waste). Crumb Rubber Plant waste is currently not being utilized optimally. The basic structure of natural rubber is a linear chain of isoprene units (C5H8) natural rubber is a polymer of hydrocarbon compounds, namely 2–methyl-1,3 butadiane (isoprene). The main purpose of this study is to determine the value of the oil combustion rate resulting from the pyrolysis of crumb rubber solid waste and find out the characteristics of the oil resulting from the pyrolysis of crumb rubber solid waste and find out the comparison of the quality of oil from crumb rubber solid waste. From this study will show the optimum amount of pyrolysis and distillation results to produce oil. Operating conditions take place at atmospheric pressure with temperature variations of 200oC, 250oC, 300oC, and 350oC for 180 minutes for the pyrolysis process which will then be distilled with a temperature of 95°C for 20 minutes. The results showed that % of the conversion of raw materials into oil (amendment) was highest for the pyrolysis process at a temperature of 350oC of 51.86% while in the distillation process pyrolysis oil with a temperature of 350oC as much as 82.55%. For the value of the combustion rate in the largest pyrolysis process with a value of 0.975  at a temperature of 350oC and a distillation process of 1,612  at a temperature of 350oC.

Abstract

Pertumbuhan ekonomi dan kemajuan teknologi akan menyebabkan tingginya penggunaan energi. Sebagian besar energi di dunia menggunakan sumber energi berbasis fosil, dimana penggunaannya menghasilkan emisi gas rumah kaca yang berdampak buruk pada lingkungan, seperti pemanasan global dan dampak negatif terhadap kesehatan manusia. Karenanya beberapa negara maju dan berkembang melakukan aksi dalam pembatasan penggunaan energi fosil dan mendorong pemanfaatan energi baru dan terbarukan yang lebih ramah lingkungan dan lebih berkelnajutan (sustainable). Diantara aksi tersebut adalah Paris Agreement pada tahun 2015 yang mendorong setiap negara melakukan kegiatan untuk menurunkan iklim global setidaknya 1,5°C – 2°C. Energi baru dan terbarukan adalah sumber daya energi alami yang dapat digunakan secara bebas, terus diperbaharui, tak terbatas, dan terus berkelanjutan. Hal-hal terpenting adalah terkait jenis, sumber, dan manfaat dari energi baru dan terbarukan. Kebutuhan manusia akan sumber daya energi tidak dapat diabaikan, karena setiap aktivitas memerlukan sumber daya, baik itu terbarukan maupun tidak. Namun, penggunaan sumber daya energi yang tidak dapat diperbaharui berlebihan telah menyebabkan kerusakan lingkungan alam yang serius dan akhirnya menghasilkan polusi yang berbahaya bagi Kesehatan manusia dan lingkungan. Dalam menghadapi keterbatasan sumber daya energi yang tak terbarukan, para ilmuwan dari berbagai negara telah mulai mengembangkan sumber daya energi baru dan terbarukan. Kegiatan pengabdian ini tidak hanya bertujuan untuk memperkenalkan konsep energi baru dan terbarukan, tetapi juga memberikan solusi konkret terhadap masalah sampah yang telah menjadi ancaman serius bagi lingkungan dan kesehatan masyarakat. Masalah sampah, khususnya limbah anorganik, telah menjadi salah satu isu utama yang dihadapi masyarakat modern. Setiap hari, tumpukan sampah kian menggunung, menciptakan dampak negatif yang signifikan, terutama ketika musim hujan tiba. Krisis ini tidak hanya berdampak pada keindahan lingkungan, tetapi juga berpotensi menyebabkan banjir yang melanda daerah pemukiman. Sampah anorganik, seperti plastik, tidak dapat terurai secara alami, sehingga memerlukan intervensi yang inovatif dan berkelanjutan. Sebagai respons terhadap tantangan tersebut, tim pengabdi mengembangkan teknologi mesin pencacah sampah anorganik yang revolusioner. Teknologi ini mampu mengubah limbah plastik menjadi serbuk atau biji plastik, sehingga memfasilitasi proses daur ulang yang lebih efisien. Dengan inovasi ini, kita tidak hanya mengurangi volume sampah, tetapi juga memberikan nilai tambah pada limbah yang selama ini dianggap sebagai masalah. Proses distilasi merupakan salah satu cara atau solusi untuk menghasilkan minyak hasil proses distilasi dengan metode pirolisis untuk bahan bakar cair dan ini menjadi salah satu sumber energi alternatif. Energi alternatif ini diperoleh dari sampah berbagai macam atau tipenya. Karena bahan bakunya berlimpah maka selain menjadi bahan bakar alternatif juga mampu menyelesaikan masalah sampah anorganik yang nyata tidak dapat diperbaharui dan dapat merusak tanah dan lingkungan.
