Strategi Starting Star-Delta Berbasis PLC untuk Pengendalian Motor Induksi Tiga Fasa yang Efisien
Three-phase induction motors are widely used in industrial systems due to their robustness and simple construction; however, the starting process often generates high inrush currents that may reduce system efficiency and accelerate equipment degradation. This study aims to develop and analyze a Programmable Logic Controller (PLC)-based star-delta starting strategy for efficient control of three-phase induction motors. The research method includes control circuit design, ladder logic programming on the PLC, and performance testing during the transition from star to delta connection. The results indicate that the PLC-based approach enables more precise starting time control compared to conventional systems, while simplifying system configuration and operational parameter adjustment without hardware modification. The proposed strategy improves control reliability, reduces installation complexity, and supports the requirements of modern industrial automation. Therefore, the PLC-based star-delta starting system represents an effective solution for upgrading three-phase induction motor control in industrial applications.

Pengembangan Sistem Pendeteksi Asap dalam Ruangan Berbiaya Rendah Berbasis Arduino Uno Menggunakan Sensor MQ-2
Smoke in enclosed indoor environments is an early indicator of fire incidents and indoor air quality degradation that may threaten occupant safety. Delayed smoke detection is often caused by the limitations of conventional alarm systems, which are relatively expensive and lack installation flexibility. This study aims to develop a low-cost indoor smoke detection system based on Arduino Uno using an MQ-2 sensor as an early warning mechanism. An experimental research method was employed, including hardware design, software development, and system testing. The MQ-2 sensor was used to detect smoke concentration and generate analog signals processed by the Arduino Uno. Warning outputs were represented by a buzzer and an LED, which were activated when the sensor value exceeded a predefined threshold. System testing was conducted under smoke-free and smoke-present conditions to evaluate system responsiveness. The results demonstrate that the proposed system can effectively detect smoke and provide real-time alerts. The developed system offers a simple design, low implementation cost, and potential applicability as an indoor safety solution.
Analisis Kebisingan dan Getaran Mekanis pada Mesin Molen Produksi Snack Kacang Telur
PT. Cahaya Anugrah Sentosa Makassar in its produktion process uses a molen machine to produce egg and peanut snacks. In the produktion process using a molen machine there are vibrations and sounds which can cause noise and vibrations which are felt by workers as a result which can disrupt work concentration. This research was carried out with the aim of analyzing the noise and vibration levels of molen machine during the production process. This research uses noise measurements using a sound level meter. Meanwhile, vibration measurements use a vibration meter. Based on the results of measurements carried out on the molen machine, the highest noise level was 80,9 dB with a motor rotation speed of 1450 rpm and the lowest was 79,5 dB. Meanwhile the measurement results of the maximum vibration level on the machine floor were 5,3 m/s2 and the minimum vibration level on the lower operator floor was 1,3 m/s2. The results of this research provide an illustration that the noise and vibration levels are lower compared to the provisions of the Indonesian Ministry of Manpower No. Kep. 51/MEN/1999 concerning the Threshold Limit Value (NAB) of noise, namely 85 dB.
