Abstract

Power Circuit Breaker (PMT) is an electrical device used to connect or disconnect the flow of electricity at medium to high voltage. The purpose of this research is to evaluate the operational feasibility condition of the PMT Vacuum Circuit Breaker 150 kV installed on the Lagadar bay line. To what extent the device still meets the technical requirements according to the applicable standards, technical testing is conducted to determine the extent to which the PMT Vacuum Circuit Breaker 150 kV still meets the technical requirements according to the applicable standards. The methods used include insulation resistance testing, contact resistance testing, and contact bounce testing. This research was conducted by comparing the test results obtained with the standards. The contact resistance test yielded the following values phase R at 37 μΩ, phase S at 34 μΩ, and phase T at 40 μΩ, all of which are below the maximum threshold of 50 μΩ according to IEC 60694 standards. Meanwhile, in the contact synchronization test, the closing times were: phase R 74.60 ms, phase S 71.15 ms, and phase T 72.05 ms, and the opening times were: phase R 24.65 ms, phase S 30.80 ms, and phase T 24.70 ms. The time differences between phases are still within the acceptable synchronization limits (below 10 ms).

Abstract

Growth and development of infants are crucial aspects that need to be regularly monitored, with height and weight serving as key indicators of nutritional status. This study aims to design and develop a technology-based system to automatically monitor the height and weight of infants using ultrasonic sensors and load cells. The system is designed to provide accurate, practical, and continuous real-time measurements, integrating technologies such as ESP32, LCD, and Blynk application. Test results demonstrate that the system achieves high accuracy with an error percentage below 1%, along with optimal performance of the ultrasonic sensor (distance up to 80 cm) and load cell (weight up to 10 kg). Among the 6 samples tested, 2 infants were categorized as undernourished, 4 as normal. This system is expected to simplify the monitoring of infant nutritional status, support early detection of health issues, and contribute to improved growth quality

Abstract

The digital poultry sector faces challenges in maintaining stable incubation temperatures. Comparative evaluation between Sugeno and Tsukamoto methods has not been conducted in real-world IoT systems. This research is essential to identify the most effective fuzzy logic control approach for smart incubators. This study aims to compare the effectiveness of Sugeno and Tsukamoto fuzzy logic methods through implementation in the SCAMIS platform. A comparative experimental design was employed using Sugeno and Tsukamoto models in SCAMIS. Temperature data were collected via DHT22 sensors and analyzed quantitatively. Code validation and sensor accuracy tests ensured data reliability and the credibility of fuzzy decision-making processes. The accuracy level of the DHT22 sensor when detecting temperature is 98.31%. The comparison of response time from initial temperature to target temperature (30°C - 38°C) between the Tsukamoto and Sugeno fuzzy logic methods is 1 : 3. Tsukamoto takes 1 hour 52 seconds (3,652 seconds), while Sugeno takes 3 hours 1 second (10,801 seconds). The response time required by Tsukamoto for each 1°C temperature increase is 1–7.5 minutes, while Sugeno is 1–10.3 minutes. However, in terms of temperature stability, Sugeno is more stable with an accuracy rate of 98.40% approaching the target temperature, while Tsukamoto has an accuracy rate of 96.93%. These results indicate a significant trade-off between the speed of reaching the target temperature and stability at the target temperature. Control method selection should align with specific operational priorities in smart incubation systems. These findings recommend choosing fuzzy methods based on system priorities. Future studies should evaluate energy consumption and hatching success efficiency.

Abstract

Motorcycle theft and robbery have drastically increased the ease of losing motorcycles in public places, especially motorcycles that do not have more safety such as keyless in general. The current motorcycle security system still uses the key as the main security or uses additional security electronic devices such as an alarm that sounds if there is a hard touch on the motorcycle. However, security like this is not fully guaranteed that the motorcycle is safe. The problem of this research is how to design a security system based on RFID, GPS and telegram applications. The purpose of this research is to design a motorcycle security system based on RFID, GPS and telegram applications that can monitor and secure motorcycle vehicles and know the difference in distance between GPS coordinate points to facilitate detection of the location of our motorcycle and also to turn on the motorcycle electricity must scan the identity of the motorcycle owner. The research method consists of hardware and software design and testing of the RFID system, GPS testing, monitoring testing through the telegram application and testing the overall electric current. In the RFID distance test, the tag is perfectly read up to a distance of ± 3 cm with a success rate of 100%. However, at a distance of ±4 cm and above, the readings were inconsistent, and above ±5 cm, the tags were not read at all. GPS sensor testing was conducted to detect the location of the motorcycle based on latitude and longitude coordinates at several points. The difference between two points is calculated using the Euclidean distance formula, where the difference in latitude and longitude is converted into meters. For example, a 1-second latitude difference is equivalent to 30.92 meters, and a 2-second longitude difference is equivalent to 61.85 meters. By calculation, a distance difference of 69.14 meters is obtained between the two points. This shows that the GPS sensor can detect position differences with sufficient accuracy

Abstract

- In this study, we investigate the potential of using state-of-the-art neural network architectures to increase the accuracy in classification of Quranic recitations per verse. Using a dataset of more than 4000 audio recordings annotated with rich metadata, the research has concentrated on differentiating accurate recitations through Hukm Al-Noon Al-Mushaddah specifications. This study uses three pre-trained deep learning models (Inception-V3, EfficientNet and MobileNet), as well as hybrid model proposed in this paper to perform classification of recitations. The raw audio inputs were converted into spectrograms for feature extraction and classification in each of the models. Experiments demonstrate that through the fusion, this hybrid model significantly outperforms individual predictions by dramatically improving precision, recall and F1-scores in five different verses. The total accuracy for the proposal model is 0.79 which is the highest comparing with Inception-V3 was 0.75 and EfficientNet was 0.73. The results underline the ability of such systems to provide immediate feedback for learners and thereby assist them in adhering to traditional recitation standards, a feature that helps maintain the originality of Quranic recitation. To enable usage on real data, further work should build a bigger dataset (samples of data) and optimize the model to providing feedback with larger latency

Abstract

Indonesia's rapid economic development and energy transition goals necessitate accurate long-term electricity demand forecasting to ensure supply security while optimizing infrastructure investments. This study addresses critical gaps in existing forecasting methodologies by developing a hybrid Grey Wolf Optimizer-Neural Network (GWO-NN) model specifically designed for emerging economy characteristics. While recent deep learning approaches (LSTM, CNN-LSTM) show promise for short-term forecasting, they often fail in long-term predictions due to limited adaptability to economic volatility and infrastructure constraints typical in developing nations. Our GWO-NN framework overcomes these limitations through intelligent hyperparameter optimization and multi-scenario modeling that captures Indonesia's unique socio-economic dynamics. The model incorporates 15 years of historical data (2010-2025) across seven key variables: GDP growth, population dynamics, temperature variations, industrial activity, urbanization rates, energy efficiency, and electrification progress. Rigorous validation against PLN's official projections reveals superior performance: Conservative scenario achieves exceptional 3.9% average absolute difference, Moderate scenario 19.0%, demonstrating significant improvement over traditional ARIMA models (35% error) and recent CNN-LSTM approaches (25% error). The 2034 demand projections range from 377.0 TWh (Conservative) to 546.1 TWh (Optimistic), providing policymakers with robust planning envelopes. This research contributes methodologically through hybrid metaheuristic optimization and practically through evidence-based planning support for Indonesia's renewable energy transition and carbon neutrality targets by 2060.

Abstract

Penerapan metode kontroler konvensional seperti kontroler Proporsional pada sistem motor servo didasarkan pada banyaknya kontrol cerdas namun masih belum mampu dalam skala implementasi terkait dengan keterbatasan sistem. Metode Kontrol Proporsional yang umum digunakan menghasilkan keluaran yang memiliki error yang relatif besar. Oleh karena itu, penelitian ini mengajukan metode kontrol proporsional modifikasi untuk mengontrol posisi pada motor servo. Penelitian ini bertujuan untuk menghasilkan keluaran sistem berdasarkan parameter error steady state dan Root Mean Square Error (RMSE). Penelitian ini dibuktikan dengan menganalisa diagram blok penerapan sistem kontroler proporsional modifikasi terhadap sistem orde satu. Selanjutnya, dilakukan analisa gain kontroler proporsional dan gain modifikasi untuk mendapatkan tuning parameter yang sesuai dengan spesifikasi yang diinginkan. Dari hasil eksperimen menggunakan tiga sinyal uji diatas, dapat disimpulkan bahwa kontroler proporsional modifikasi mampu mempercepat respon terbukti dengan nilai delay time sebesar 0,1 detik. Selanjutnya untuk kontrol posisi motor servo, metode kontroler proporsional modifikasi terbukti mampu mengikuti perubahan posisi pada masukan linear dan nonlinear. Pada masukan linear memiliki nilai RMSE 1,1561 dan masukan nonlinear memiliki RMSE yaitu 2,5913.
