Abstract

The electrical network system is the process of distributing electrical energy from power plants to end-users through distribution networks and substations. The distribution network's primary function is to reduce high-voltage electricity, typically from 150 kV to 20 kV, while substations further lower it to a low voltage of 220 VAC for consumer use. However, over time, supporting equipment such as panels, cables, and transformers in the electrical network system can experience a decrease in quality, with a potential decline of up to 20% over 10 years. This degradation is due to various factors, necessitating the installation of protective measures and routine or annual maintenance to prevent potential risks. To maintain equipment quality, maintenance activities include cleaning, testing protection devices, and coordination between substations and workers. These measures are essential for the efficient operation and the successful distribution of electricity. This study evaluates the reliability of equipment at substation panel P50, with test results indicating insulation resistance values of 64,500 MΩ, 73,600 MΩ, and 87,100 MΩ, as well as a delta time of 0.7 ms. The test results indicate that the equipment's reliability is still classified as good, in compliance with the Puil 2000 and IEC 62271-100 standards.

Abstract

PT. X, an oil and gas service company in Indonesia, has a client facing safety risks at one of PT Y’s cementing assets. The client requested the implementation of an emergency shutdown component to mitigate the risk of accidents at the site. The primary challenge was the potential operational safety failures during cementing operations, which could lead to serious incidents without additional safety measures. This study aims to design and implement an emergency shutdown system based on the Omron CP1L to enhance operational safety at the cementing asset. The RES system was developed through a process of requirement identification, design, integration, and testing, supported by relevant literature studies. The system’s design includes the selection of appropriate hardware and software, as well as the development of logic to execute the shutdown when PT Y’s crew presses the emergency push button. Testing results indicate that the RES functions with an average delay time ranging from 1.5 to 1.9 seconds. The conclusion from this study is that the RES system is effective in enhancing operational safety and minimizing risks at PT Y’s cementing asset.

Abstract

Kekeringan yang diakibatkan oleh musim kemarau adalah tantangan utama pertanian yang dihadapi oleh masyarakat Dusun Joho, Kecamatan Cepu, Kabupaten Blora. Keterbatasan akses energi listrik di tengah areal persawahan dan air bersih untuk pengairan yang dicukupi melalui sumur tengah sawah menjadi hambatan dalam menjaga ketahanan ekonomi lokal. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menyediakan inovasi teknologi melalui penerapan sistem pompa air tenaga surya off-grid yang dilengkapi dengan water pumped storage dan alat pipil jagung berpenggerak motor DC. Kegiatan ini dirancang tidak hanya untuk memberdayakan masyarakat lokal dalam menghadapi permasalahan kekeringan, tapi juga memberikan ruang pembelajaran aplikatif bagi Mahasiswa dalam implementasi teknologi energi terbarukan. Hasil kegiatan menunjukkan bahwa sistem berfungsi dengan baik dan memberikan manfaat langsung kepada masyarakat. Lebih jauh, kegiatan ini secara praktis mendukung pencapaian beberapa tujuan Sustainable Development Goals (SDGs), yaitu SDG 1 (Tanpa Kemiskinan), SDG 4 (Pendidikan Berkualitas), SDG 7 (Energi Bersih dan Terjangkau), SDG 9 (Inovasi dan Infrastruktur) dan SDG 13 (Penanganan Perubahan Iklim)

Abstract

Currently, Carbon Capture, Utilization, and Storage (CCUS) systems are emerging as a significant focus in discussions of climate change. CCUS refers to a set of technologies designed to capture Carbon Dioxide (CO2) emissions from various sources and either utilize it for beneficial purposes or store it to prevent release into the atmosphere. CO2, the primary gas responsible for the greenhouse effect, is generated across multiple sectors, notably in energy and transportation. In Indonesia, the energy sector is the most significant contributor to CO2 emissions, accounting for 697.97 million tons in 2022. In this study, we have developed a cost-effective carbon capture device utilizing the Direct Air Capture (DAC) method. This device uses a microcontroller as the primary control unit, along with a compact closed chamber serving as the main reactor. Sodium hydroxide (NaOH) was utilized as the absorbent in our study. We conducted experiments on this device, keeping the NaOH concentration and reaction time fixed while varying the absorbent flow rate as the independent variable. The experiment yielded quite promising results. The absorption of CO2 is directly related to both the flow rate of the absorbent and the reaction time. The maximum CO2 absorption recorded is 3.960 ppm, achieved at a flow rate of 10 liters per minute with a reaction time of 5 minutes. The results have been reconfirmed by chemical titration.
