Abstract

The increasing demand for electricity requires PT. XYZ to provide a sufficient, reliable, safe, high-quality, and efficient source of electrical energy. In serving customers, especially those in the Medium Voltage (MV) category, good protective equipment is needed. However, conventional protective equipment often tends to be large, requires ample land space, and installation is time-consuming. This research covers variables such as contact resistance measurement, PMT (Power Circuit Breaker) synchronism testing, and insulation resistance measurement. Using the Research and Development (R&D) method, the results of maintenance on the 20 kV PMT at PMCB KPI P. Sidomulyo, Buduran Subdistrict, revealed that the contact resistance measurement values for phases R, S, and T were below 100 µΩ, indicating good contact resistance. PMT synchronism testing produced time difference values that were within the permissible standard limits. The time difference when opening (open) was 0.7 ms, while when closing (close), it was 1.05 ms. Insulation resistance measurements showed values that met the standards, which were above 20 MΩ. Based on the research results, PMCB KPI P. Sidomulyo, Buduran Subdistrict, can still be considered suitable for use. With good protective equipment and measurements that meet the standards, the use of 20 kV PMT can remain efficient and safe for consumers.

Abstract

This research develops and tests a prototype forklift robot controlled via an Internet of Things (IoT)-based system using an ESP32 microcontroller and the MQTT protocol. Designed to overcome the limitations of traditional manual forklifts, the robot enhances warehouse operations by increasing efficiency and minimizing human error. The study presents the design, testing, and evaluation of the forklift robot's movement control, mechanical wheel performance, load capacity, and wireless connectivity across various Android devices and network providers. Testing was conducted over distances ranging from 1 km to 90 km with different Android devices (e.g., Samsung, Xiaomi, OPPO, Vivo) and providers (Indosat, Axis, Telkomsel, Smartfren). The robot successfully performed a variety of movements, including forward, backward, left, right, rotation, and lifting operations. It demonstrated stable load lifting capabilities up to 300 grams, with instability observed for heavier loads, and could operate smoothly across a range of network conditions. Connectivity tests showed consistent performance and stable communication, reinforcing the robot's practical use for remote control and real-time monitoring. This research emphasizes the potential of IoT-enabled forklift robots to optimize material handling processes in warehouses, contributing to safer and more efficient industrial environments
