ABSTRACT Three-phase induction motors are widely used in industry due to their high reliability and efficiency; however, conventional control systems have limitations in terms of remote operation and monitoring. This research designs and implements a start–stop control and current monitoring system for a three-phase induction motor based on the Internet of Things (IoT) using an ESP32 mic…
ABSTRACT The design and construction of a solar-powered water pump system for pool water circulation was carried out to provide an efficient and sustainable alternative energy solution. This system utilizes solar modules as the primary energy source, converted by an inverter to produce AC voltage suitable for the pump's needs. An MPPT controller (MPPT) is used to optimize power absorption …
ABSTRACT Three-phase electric motors are the type of motor that is most widely used in both large and small industries compared to other types of motors. This is possible because this type of motorbike has advantages both from a technical and economic point of view. Three-phase electric motors have large initial current characteristics but this can be overcome by several methods of regulation,…
ABSTRACT This study discusses the design of a monitoring system for current, voltage, and power in a three-phase induction motor based on the Internet of Things (IoT). The system uses an ESP32 microcontroller as the main controller and PZEM-004T sensors to measure electrical parameters. Measurement data are transmitted via WiFi and displayed on the Blynk platform, allowing real-time monitoring…
ABSTRACT Corn sheller machine functions to separate corn kernels from the cobs. Corn sheller is a tool designed to improve and speed up the shelling results. With this mechanical corn sheller machine design, corn shelling work is more effective and efficient compared to manual shelling such as traditional shelling by hand, shelling with the tpi model, and the large method. The design results c…

ABSTRAK Onion (Allium cepa L.) is an important horticultural commodity that is widely used as a basic seasoning in various dishes. The high demand for onions requires increased efficiency in the peeling and slicing process. Onion peeling and slicing machines on the market today generally use a vertical system, but have limitations such as imperfect peeling results, risk of leakage during the p…
ABSTRACT The design and manufacture of an off-grid solar panel monitoring system integrated with temperature and light intensity sensors based on the Internet of Things (IoT) is discussed in this study. The background of this study stems from the need for an automatic monitoring system to determine the performance of solar power plants (PLTS) in real time without having to make manual records.…
Abstract Waste is the residue of human activities or natural processes that is no longer used, discarded, and has no economic value for its owner. The problem of waste in waterways, especially rivers, is a crucial environmental issue. The accumulation of trash in rivers not only pollutes the environment and damages aquatic ecosystems, but can also cause flooding. This thesis designs an IoT-bas…
ABSTRAC This study aims to design and implement an analog-based Battery Management System (BMS) utilizing a TL431 comparator and a BD140 transistor to provide overcharge protection for a 3S lithium-ion battery configuration. The proposed system is integrated with a 10-Watt photovoltaic (PV) solar panel as the energy source and is equipped with a monitoring subsystem consisting of an INA219 cur…
ABSTRAK The development of information and communication technology has driven an increasing need for fast and stable internet access, especially through public WiFi networks that are now widely available in cafes, restaurants, and other public spaces. This study aims to measure and analyze the quality of service (QoS) and the quality of user experience (QoE) on open access WiFi networks i…
ABSTRAK This study aims to analyze and compare the performance of 4G LTE networks provided by two cellular operators, Telkomsel and 3 (Tri), in Pekanbaru City. Measurements were conducted in three different environments, namely urban, sub-urban, and indoor areas, using drive test methods. The evaluated performance parameters include Reference Signal Received Power (RSRP), Reference Signal…
