Abstract

Energi angin adalah salah satu sumber energi terbarukan yang bisa dimanfaatkan di berbagai lokasi, termasuk di daerah pegunungan, dataran rendah, hingga wilayah perairan laut. Karena jumlah angin yang melimpah di Indonesia, itu adalah salah satu jenis energi listrik yang paling efisien untuk digunakan. Di sisi lain energi angin membutuhkan turbin angin untuk pengkonversian energi angin menjadi energi kinetik yang diubah menjadi energi listrik, tetapi turbin angin ini juga sangat bergantung terhadap kecepatan angin. Estimasi kerapatan energi angin diharapkan mampu untuk menentukan kelayakan atau potensi sumber energi angin pada turbin angin berdasarkan data klasifikasi kerapatan angin. Hasil menunjukkan algoritma mampu mengklasifikasikan kerapatan energi dengan akurasi 87.3%, dimana kecepatan angin berkontribusi paling signifikan (45.2%) terhadap fungsi diskriminan.

Abstract

This study aims to design and implement a smart kWh meter system based on ESP32 that is capable of monitoring and controlling electricity consumption in households with a connected power of 1300 VA. The developed system utilizes the ESP32 microcontroller as the main data processor, which is integrated with the PZEM-004T sensor to measure electrical parameters, including voltage, current, power, energy, and power factor. Measurement data is displayed in real-time through the Blynk application, while control and limitation of energy consumption are managed using a Telegram bot service. The system is equipped with a relay to automatically disconnect the load when energy consumption exceeds a predetermined limit. System testing is conducted by comparing the sensor measurement results against the PLN kWh meter as a reference tool. The test results indicate that the developed smart kWh meter system operates effectively and possesses an average current measurement accuracy of above 99% across various types of household loads. Additionally, the load control and notification system based on Telegram functions reliably in limiting electricity consumption. Therefore, this system can serve as an effective solution to assist household users in monitoring and controlling electricity consumption more efficiently.

Abstract

Indonesia memiliki potensi energi surya yang besar sehingga pemanfaatannya pada sistem Penerangan Jalan Umum (PJU) berbasis tenaga surya sangat prospektif, namun panel surya dengan posisi statis belum mampu menyerap energi secara optimal akibat perubahan sudut datang sinar matahari sepanjang hari. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan solar tracker single-axis terhadap daya keluaran panel surya pada sistem PJU. Metode yang digunakan adalah metode eksperimental dengan membandingkan kinerja panel surya statis pada sudut 45°, 90°, dan 135° dengan panel surya dinamis yang dilengkapi sistem solar tracker single-axis berbasis Arduino Uno. Parameter yang dianalisis meliputi tegangan, arus, daya keluaran, dan persentase penyerapan energi, dengan pengujian dilakukan dari pukul 06.00 hingga 17.00 pada interval 30 menit. Hasil penelitian menunjukkan bahwa panel surya dengan sistem pelacak menghasilkan daya keluaran yang lebih tinggi dibandingkan panel statis, dengan total daya keluaran panel dinamis mencapai 64,84 W, sedangkan panel statis menghasilkan daya antara 31,25 W hingga 40,06 W. Selain itu, tingkat penyerapan energi panel surya dinamis mencapai 87,51%, lebih tinggi dibandingkan panel surya statis yang berada pada kisaran 42,18%–54,06%. Hasil ini menunjukkan bahwa penerapan solar tracker single-axis efektif dalam meningkatkan daya keluaran dan efisiensi energi panel surya pada sistem PJU.

Abstract

The precise mixing of paint colors is crucial in painting industry. This process requires high accuracy and skill in measuring the base colors needed to produce the desired final color. But in most case paint mixing process still be done in a manual way which can pose risks, such as generating inconsistent or inaccurate colors. Based on these conditions this research aims to design paint mixing device to assist in achieving more accurate and efficient color mixing process by using Arduino as the main processor to control paint measurements through integration with TCS-3200 sensors and actuators to improve efficiency and the quality of color mixing based on specific requirements. Result of the tests showed that the device able to perform a promising result, with the average error value of just 9,61%. Several factor which may affect of the results include light ambience condition around the device, paint color calibration, and uniformity in of the paint color used.

Abstract

Precise position control of AC induction motors is essential in various industrial applications, including robotics, machine tools, and automated manufacturing systems. The main challenges arise from the nonlinear dynamics of induction motors and the lack of inherent position feedback. This study proposes a three-tier cascaded control architecture integrating a PD position controller, a PI speed controller, and a Field-Oriented Control (FOC) current loop, with a 1:10:100 bandwidth hierarchy among the loops. This design ensures effective dynamic decoupling and global asymptotic stability, verified through Lyapunov-based analysis, including robustness against rotor parameter uncertainties up to ±20%. Numerical simulations on a 1.5 kW induction motor demonstrate a rise time of 0.157 s, settling time of 0.267 s, overshoot of 9.8%, steady-state position error of 0.0008 rad, and disturbance rejection of a 2 N·m load in 95 ms. FOC implementation maintains rotor flux within ±0.1% and peak efficiency of 91% at rated torque. These results confirm that the proposed cascaded three-tier FOC architecture achieves fast, accurate, and stable position control suitable for industrial servo applications and can be extended to other AC motor types with parameter adjustment and flux control strategies.

Abstract

Sistem Evaluasi Layanan Lengkap Individu dan Catatan Aktivitas (SELLICA) was initially built using a monolithic architecture based on Next.js API routes. However, as the user scale increased, the system experienced performance and efficiency bottlenecks under heavy workloads. This study aims to conduct a comprehensive comparative analysis between an integrated Next.js backend architecture and a separated, service-oriented Go (Golang) backend for government-scale applications. The research method employs quantitative evaluation through performance testing (load testing with K6 and benchmarks) as well as qualitative evaluation of architectural complexity and development experience. The results indicate that migrating to a Go backend provides a response time improvement of 20 to 289 times faster, 20.25 times higher throughput, and memory usage efficiency up to 4 to 5 times lower compared to Next.js. Conversely, Next.js maintains advantages in rapid initial development and prototyping ease. In conclusion, for large-scale systems with stringent performance and concurrency requirements, a Go backend is highly recommended. A hybrid architectural approach, combining a static Next.js frontend with a Go backend, proves to be the most optimal solution in balancing high performance and cost efficiency.

Abstract

Electric power is essential for daily activities; however, power outages frequently disrupt electricity supply, particularly for small-scale applications such as egg incubation in free-range poultry farming. The incubation process requires continuous electrical energy to maintain heat using a 15-watt lamp for approximately 21 days. To address this issue, alternative energy sources, especially solar energy, can be utilized through photovoltaic (PV) systems. However, PV systems inherently produce unstable output voltage due to fluctuations in solar irradiance, which may affect battery charging performance. To overcome this limitation, a Buck-Boost converter is implemented to regulate and stabilize the PV output voltage. In addition, temperature and humidity sensors are integrated into the incubator system to ensure optimal environmental conditions for egg hatching. Experimental results show that the Buck-Boost converter successfully stabilizes the PV voltage at 14 V, with an average current of 1.5 A in the first week, and 1.4 A in both the second and third weeks. Furthermore, the incubator maintains an average temperature of 37°C and humidity of 56%, which fall within the recommended range for successful egg hatching. These results indicate that the proposed system is capable of providing a stable energy supply while maintaining suitable incubation conditions.

Abstract

This study analyzes the performance of the Message Queuing Telemetry Transport (MQTT) protocol in a hazardous gas monitoring system using an MQ135 sensor and an ESP8266 NodeMCU microcontroller, integrated with a Flutter-based Android application. The monitored gases include CO, NO₂, CO₂, and SO₂, based on the threshold limits set by Permenaker No. 5 of 2018. The objective of this study is to evaluate MQTT Quality of Service (QoS) parameters, including delay, jitter, packet loss, and throughput, across three QoS levels (0, 1, and 2). Sensor validation was conducted using the Repeatability Test and Threshold Detection Test. The results show that the sensor demonstrates good reliability with CV values ranging from 1.92% to 3.78% and an average detection success rate of 98.9%. MQTT testing indicates that QoS 0 achieves the lowest delay (42.3 ms), jitter (3.12 ms), and zero packet loss, and the highest throughput (18.6 kbps). Additionally, the system provides real-time notification with an average response time below 500 ms. However, QoS 1 is identified as the optimal configuration, balancing delivery reliability and network efficiency for real-time laboratory safety monitoring systems
