Abstract

To minimize production down time that caused by equipment damage, it is necessary to have sufficient spare part availability. But sometimes this is hard to fulfill because of the price of spare parts and there are any specifications that are difficult to find. One of the equipment that has a vital role in steel manufacturing process is a gas valve actuator that has a function to regulate the flow of gas volume used in the billet reheating process. Most actuator problems are caused by the control circuit, while the mechanical and actuating devices can still work normally. Replacing the actuator unit will require a large cost, as well as a relatively long response time. From these problems, a control system is designed that can be applied to the actuator units that are already available by utilizing Arduino UNO as a processor, to reduce down time due to equipment damage. The method applied to this tool is to compare the input signal value with the actual gas valve opening position from the potentiometer. Based on the results of data collection shows this control system has an average error value of 0.7075%. The results of the tests carried out show that the Arduino UNO-based control system can operate the actuator unit effectively, to be used in the billet reheating process.

Abstract

Nusa Tenggara Timur memiliki nilai rasio elektrifikasi paling rendah di Indonesia. Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) dinilai mampu mengatasi krisis energi listrik pada daerah yang sulit dicapai. Kajian ini bertujuan untuk mengetahui potensi energi mikro hidro dari sungai yang ada di Pulau Timor. Penelitian dilakukan dengan pengumpulan data informasi aliran air sungai di Pulau Timor, seleksi data berdasarkan debit air sungai, dan perhitungan potensi kapasitas daya terbangkit dari masing-masing sungai. Dari hasil penelitian didapat 5 sungai di Pulau Timor yang memiliki potensi untuk didirikan PLTMH yaitu Mota Benanain, Noe Muti, Noel Mina, Mota Hasfuik, dan Mota Ponu dengan potensi total kapasitas daya yang bisa dibangkitkan adalah sebesar 102,62 kiloWatt(kW).

Abstract

Breakdown produksi merupakan salah satu peristiwa yang harus diminimalisir, bahkan dieliminasi pada setiap proses produksi di sektor industri. PT. X sebagai salah satu produsen baja nasional juga berupaya untuk mengoptimalkan proses produksi, mengingat modal yang dibutuhkan untuk memproduksi baja memiliki nilai yang relatif tinggi. Breakdown produksi perlu dianalisis dengan baik untuk mendapat solusi yang tepat dan akurat. Salah satu alat yang dapat digunakan adalah fishbone diagram. Berdasarkan data yang diperoleh diketahui dua kendala yang paling dominan terjadi selama periode Desember – Mei terjadi pada area Crop Shear (21%) dan Flying Shear (19%). Adapun pada area Crop Shear diketahui motor trip akibat terindikasi overspeed, sedangkan pada area Flying Shear motor bekerja abnormal akibat ada indikasi pompa oli yang mati. Tindakan perawatan dan perbaikan lalu dirancang berdasarkan hasil analisis yang didapat, yaitu penggantian parameter kerja motor Crop Shear, dan penggantian kabel indikator oil flow untuk motor Flying Shear. Hal ini perlu direalisasikan untuk mengantisipasi hal semula terjadi di masa mendatang melalui corrective dan preventive maintenance.Kata kunci: industri baja, diagram tulang ikan, diagram pareto, perawatan

Abstract

This community service project is an implementation of research findings. Hydroponic farming offers an innovative solution to land scarcity and soil degradation in urban areas. Its success heavily depends on the management of nutrient solution quality, particularly in terms of electrical conductivity (EC) and temperature. In the local hydroponic farm, residents were still using manual methods that are inaccurate and lack data logging capabilities. Therefore, an EC and temperature sensor-based monitoring system integrated with LabVIEW was developed. The system is designed to provide real-time readings, color-coded visual indicators, and automatic data logging. Testing was conducted over six days at a lettuce hydroponic installation, yielding an average EC deviation of 3.2% compared to a reference device. The measured temperature range remained within the ideal range (26.1–28.3°C). The system operated stably with a 1-second reading interval, low power consumption, and compatibility with local conditions. Positive user feedback highlighted its ease of use and practical benefits in plant maintenance decision-making. Through this appropriate technology approach, the system has the potential to serve as a model for smart household-scale agricultural development in urban areas

Abstract

A milling process utilize DC motors and rectifier circuits. Semiconductor components in the rectifier circuit could cause harmonic distortion. At PT X, the voltage THD generated at the 6KV feeder panel has exceeded the standards set by the IEEE. This study aims to analyze the voltage THD caused by a controlled rectifier circuit and DC motors, and to design a filter to mitigate it. MATLAB software is used to analyze the THD voltage. From the simulation results, it is known that the 400KW, 450KW, and 600KW DC motors produce voltage THD values of 9.35%, 14.23%, and 12.28% respectively which exceed the set standards of 8%. A single-tuned passive filter is designed to reduce the THD voltage value on each motor. The installation of the filter effectively reduces the THD voltage value in the 400KW, 450KW, and 600KW DC motors to 4.34%, 5.38%, and 6.35% respectively.

Abstract

Soil moisture monitoring is essential for precision agriculture to optimize irrigation and increase crop productivity. Traditional conductivity-based sensors often face limitations such as low sensitivity, slow response, and measurement instability. This study presents a simple and effective enhancement method by applying a graphene coating on copper electrodes using the drop casting technique. Experimental evaluations were conducted on natural soil samples at varying moisture levels. The graphene-coated sensor exhibited a significantly higher sensitivity of 23.0 Ω/% compared to 12.0 Ω/% for the uncoated sensor, a faster response time of approximately 5 seconds, and improved measurement consistency with a reduced standard deviation of ±15 Ω. Graphene's superior electrical conductivity and strong water affinity are key factors contributing to this performance improvement. These findings indicate that graphene-coated sensors offer a promising solution for reliable, cost-effective soil moisture monitoring in smart farming systems.
