Abstract- Low-Voltage Connect Device (PHB-TR) are vital components in low-voltage electrical distribution systems that ensure the safe and reliable flow of electricity to various equipment and circuits. Feasibility studies of low-voltage connecting devices are key to ensuring optimal panel performance and safe operation. This study details the results of work in the feasibility test of connecting devices for low voltage covering various stages, such as panel construction, PHB-TR electrical characteristics, PHB-TR components, and Transformer Pole Substation (GTT). The feasibility testing process starts by measuring the load of the G.248 T Padang distribution substation and also considering factors such as determining the NH Fuse current, determining the size and KHA of the busbar, determining the insulation resistance of the cable, and determining the grounding resistance of the GTT according to and the protection required. Final documentation includes test notes, modeling using applications and software, and other important information needed for future maintenance and repairs. The result of the feasibility study of this low-voltage connecting device is that it is well installed, complies with applicable safety and technical standards, and can support reliable electricity flow to connected equipment. With careful planning, low-voltage connecting devices will serve as critical components in an efficient and reliable low-voltage power distribution system.

One of the most profitable processed banana products is banana sale. To produce high quality banana sale, an effective and consistent drying process is essential. The purpose of this research is to create and build an Arduino microcontroller-based banana dehydrator that can optimize the drying process. It is equipped with a temperature and humidity sensor (DHT22) to track the environmental conditions inside the dehydrator. In addition, heating elements and fans are equipped to control air circulation and temperature. The designing starts with creating a comprehensive system design. This includes the system block design, electronic circuit schematics, as well as the physical design of the device itself. An Arduino program is designed to use data from the temperature and humidity sensors to control the heating elements and fans, ensuring an ideal drying environment. Intensive testing was conducted to ensure that the device operates properly and can achieve optimal drying conditions for banana sale. The test results show that the dehydrator is able to dry banana plantains with higher efficiency, maintaining the temperature and humidity inside the device within the desired parameters. In addition, it also improves the quality of the final product consistently. It provides a more efficient and affordable solution for small and medium entrepreneurs in the banana processing industry. Therefore, it is expected that this tool will help increase production, reduce operational costs, and improve the quality of banana sales throughout Indonesia.

Design and Build an Electrical Installation Control System for Resitential Houses on the Internet of Things

Technological development has become a vital necessity for every individual in today's digital era. Increasingly pressing environmental issues demand energy efficiency, especially at the household level, contributing significantly to global energy-saving efforts. This research aims to implement an Internet of Things (IoT)--based electrical installation control system, which allows remote control of electrical installations via an Internet connection. This system is expected to increase the efficiency of electricity usage, as well as improve time efficiency and convenience in daily activities. The method used in this research involves using NodeMCU ESP8266 and the Blynk application to turn on or off the electric current on the connected devices. The system allows two modes of operation: manual through the selector switch and automatic through the Blynk app. Test results show that the system works well, allowing remote control without geographical restrictions as long as there is an internet connection. The speed and stability of the internet connection proved to be a crucial factor affecting the system's performance, where slow or unstable internet can cause delays or failures in command execution.

Automatic Plant Sprinkler With Source Solar Panel

2025-02-07T02:09:49+00:00

Abstract— Plant watering is an activity that needs to be considered in plant maintenance to maintain food intake dan plant growth. Plant owners in Balingka usually water the plant manually in the morning and evening so it takes a lot of time and energy during the watering process. Farmers cannot leave the plants for a long period of time because the plants will lack water wich can inhibit plant growth. So an automatic olant sprinkler is made with RTC ( Real Time Clock ) sensor, Raindrops Sensor Module, Relay1 channel and LCD ( Liquid Cristal Display ). The principle of this tool is to set the plant watering time according to the hour that has been determined using RTC ( Real Time Clock ), which is then controlled by Arduino mega 2560 to activate the relay to the automatic plant watering pump and Raindrops sensor module as a relay breaker if at the time of watering rain and the result will be displayed on the LCD ( Liquid Crystal Display ). The benefit of this automatic plant sprinkler is to facilitate in Balingka in the procces of watering strawberry plants.

Keywords : Automatic Plant Waterer, RTC ( real Time Clock ), Relay, LCD ( Liquid Crystal Display ), Raindrops Sensor Module, Arduino Mega 2560.
