Abstract

Umumnya lampu pada kamar hotel masih menggunakan saklar manual, sehingga lampu hanya bisa dioperasikan secara manual. Dengan demikian konsumsi daya listrik tidak bisa terkontrol secara baik, hal ini karena kebiasaan yang kurang disiplin terhadap penggunaan daya listrik. Atas dasar permasaalahan tersebut penulis membuat alat pengontrol lampu kamar hotel yang bisa memonitor lampu pada tiap kamar dan mengendalikannya melalui PC. Alat ini dirancang dengan memanfaatkan komunikasi multidrop RS485 dan mikrokontroler AT89S51 sebagai pengendali utama, dimana PC/komputer berfungsi untuk menampilkan kondisi lampu dan memberikan perintah pada mikrokontroler untuk mengendalikan lampu. Informasi yang diterima oleh komputer dari mikrokontroler diperoleh melalui jaringan multidrop RS485, begitu pula perintah yang diterima mikrokontroler oleh PC diterima melalui jaringan multidrop RS485. Rangkaian terdiri dari dua grup/drop, dimana tiap satu drop mengoperasikan dua buah lampu. Dari hasil uji coba yang telah dilakukan menunjukkan bahwa rangkaian ini bekerja dengan baik, hal ini dibuktikan software PC dapat berkomunikasi dengan rangkaian jaringan multidrop RS485 dan lampu dapat dikendalikan oleh PC. Masih terdapat kekurangan pada alat ini yakni terkadang relay yang bertugas menyalakan lampu terkadang masih memiliki selisih waktu dari perintah yang dilakukan software PC.

Abstract

Accurate forecasting of global horizontal irradiance (GHI) is critical for optimizing solar power plant (SPP) output, particularly in tropical locales where solar potential is high yet underutilized due to forecasting challenges. This research aims to enhance GHI prediction in one of the major cities of Indonesia, where existing models struggle with the area’s natural climate unpredictability. Our analysis harnesses a decade of data 2011-2020, including GHI, temperature, and the Sky Insolation Clearness Index, to calibrate and compare these methodologies. We evaluate and contrast the exponential smoothing method versus the more complicated artificial neural network (ANN). Our findings reveal that the ANN method, notably its fourth iteration model with 12 input and hidden layers, substantially outperforms exponential smoothing with a low error rate of 1.12%. The use of these methodologies forecasts an average energy output of 252,405 Watt for a solar panel with specification 15.3% efficiency and 1.31 m2 surface area throughout the 2021 to 2025 timeframe. The work offers the ANN method as a strong prediction tool for SPP development and urges a further exploration into more advanced forecasting methodologies to better harness solar energy.

Abstract

The electricity demand continues to rise alongside population growth, making the reliable distribution of electrical energy to consumers essential. The reliability of the 20 kV electricity distribution system on the CWRU feeder at the National Electricity Company (Perusahaan Listrik Negara, PT PLN) Customer Service Unit (Unit Layanan Pelanggan, ULP) Pelabuhan Ratu Area Surade was evaluated. The primary purpose was to analyze key reliability indices such as system average interruption frequency index (SAIFI), system average interruption duration index (SAIDI), customer average interruption duration index (CAIDI), average service availability index (ASAI), and average service unavailability index (ASUI), and to assess the economic impact of disruptions on consumers. Methodologies involved collecting and analyzing field data from PT PLN (Persero) ULP Pelabuhan Ratu’s CWRU feeder, utilizing quantitative reliability calculations and qualitative observations to identify internal and external factors affecting system reliability. The results showed that the SAIFI value reached 52.077 times/customer/year, and the SAIDI value was 99.400 hours/customer/year, classifying the system as unreliable based on PLN standards (standar PLN, SPLN) 68-2:1986. However, the CAIDI value of 1.813 hours/times/year indicated that the system response time was within acceptable limits. The availability of electricity, with an ASAI of 99.828% and an ASUI of 0.172%, was deemed satisfactory. Internal factors contributed to 10.47% disturbances. In contrast, external factors (weather and tree fall) accounted for 48.84%, and the remaining 40.69% were from unknown causes. Economic losses were calculated at Rp52,432.50/customer because these interruptions. More frequent maintenance and the implementation of additional protective measures are recommended to enhance reliability.

Abstract

Recognizing the critical contribution of the engineering field to national human resource development and innovation, coupled with the existing challenge of low student interest in engineering careers among Indonesian high school students, this study aims to analyze the influence of STEM Interest and Academic Self-Efficacy (ASE) on Engineering Study Intention (ESI) through the mediating role of Engineering-Oriented Career Identity (EOCI).  Using a quantitative survey approach, data were collected from 695 students participating in the university entrance selection process. Instruments were adapted from prior validated studies and measured on a 1–6 Likert scale. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 3. Based on the processed data, the findings reveal that both STEM Interest and ASE significantly foster the development of EOCI among students (β = 0.420 and β = 0.425, p < 0.001). In turn, EOCI strongly predicts ESI (β = 0.654; p < 0.001). However, the direct effects of STEM Interest and ASE on ESI were non-significant, confirming that EOCI fully mediates the relationship. This indicates that students' motivation and confidence affect their intention to pursue engineering primarily through identity development. The model explains 45.1% of the variance in EOCI and 43.6% in ESI, with satisfactory convergent and discriminant validity and good model fit (SRMR = 0.039, NFI = 0.948). These findings affirm the importance of forming an engineering career identity in supporting students' transition to engineering education. Practical implications include strengthening motivational programs and engineering career exploration from secondary education.

Abstract

Geothermal Power Plant (PLTP) is one of the renewable energy sources that supports the national energy transition. One of the important components in the PLTP system is the cooling tower which functions to lower the temperature of the condensed water so that it can be reused in the thermodynamic cycle. This study aims to analyze the performance of the cooling tower at PLTP Kamojang Unit 4 owned by Januari Pertamina Geothermal Januari using the Range and Approach methods based on the ASME PTC 23-2003 standard. Data were obtained from operational logsheets during the period from 4 to 10 January 2025 and analyzed using Microsoft Excel. The parameters observed included inlet water temperature, outlet water temperature, and wet bulb air temperature. The results of the analysis showed that the range value ranged from 35.61°C to 36.48°C, the approach value between 4.73°C to 5.12°C, and the effectiveness of the cooling tower was in the range of 87.42% to 88.52%. These values indicate that the cooling tower is still operating at high efficiency. Daily fluctuations in these values are influenced by environmental factors such as air humidity, wet bulb temperature, and variations in cooling load. In addition, internal factors such as fan conditions, water spraying, cooling water quality, and media packing conditions also contribute to system performance. Based on these results, it is recommended that regular monitoring and preventive maintenance be carried out to maintain the efficiency of the cooling system. With improvements and digitalization of monitoring, the cooling tower at PLTP Kamojang Unit 4 can continue to support power plant operations optimally and sustainably.

Abstract

Geothermal energy is one of the potential and sustainable renewable energy sources in Indonesia. The efficiency of the generation system is one of the crucial aspects in optimizing the utilization of this energy. This study aims to analyze the performance of synchronous generators at the Kamojang Unit 5 Geothermal Power Plant based on power, current, and voltage parameters. The method used is a quantitative descriptive approach with field data collection for seven consecutive days in January 2025. The data observed include active power, apparent power, power factor, terminal voltage, phase current, and generator efficiency and current imbalance between phases. The results showed that the generator had high and stable daily efficiency with an average of 93.99%. The power factor was also classified as good, with an average of 91.23%. The highest phase current imbalance occurred in phase V with an average of 1.60%, but was still within the safe threshold according to IEEE standards. These findings indicate that the generation system at the Kamojang Unit 5 Geothermal Power Plant operates in an efficient and stable condition. This study also indicates the importance of monitoring operational parameters periodically as part of a maintenance strategy and increasing the reliability of geothermal power plants. With high efficiency and system stability, Kamojang Unit 5 Geothermal Power Plant can be a model for reliable and sustainable renewable energy power plant operation.
