Abstract

Banjarwaru Village is located in Nusa Wungu District and has several hamlets connected to the main road as access to transportation facilities. The lack of street lighting hampers the activities of village residents, especially at night. Road points that do not have public street lighting are far from residents' homes, so they cannot use PLN electricity sources. Seeing the conditions explained above, the need for technology with energy sources that utilize renewable energy such as solar power to supply power to public street lights has been widely implemented. Making street lights with a solar power supply with the application of modern technology is the main priority in this community service activity. The main target objective of this Community Service is the Public Street Lighting Program through the manufacture of street lights with power supply from solar energy. The implementation method in this service is through observation and experiments in the field in the process of designing and manufacturing public street lights and handing over technology transfer to the community. The results of making public street lights with solar energy supply using Arduino Mega which functions to receive data from the LDR sensor and is continued with testing battery charging with solar power. The installation of the LDR sensor will help the efficiency of the lights because it will control the lights to turn on automatically. The results of the manufacture of public street lights also provided assistance and training to the Banjarwaru Village community regarding how the equipment works and the repair process if problems arise in the future.

Abstract

Optimal lighting and air conditioning are factors that support the feasibility and comfort of a room. Lighting and air conditioning requirements refer to the provisions contained in the Indonesian National Standard (SNI). The selection of lamps for lighting, Air Conditioner (AC) and Exhaust Fan for air conditioning needs to be adjusted to the needs of the room so that the device can work optimally and efficient electrical energy. The design of lighting needs and room temperature comfort is still done manually, resulting in inefficiency in the building design process. Therefore, this research aims to build an Android application to calculate indoor lighting and air conditioning needs. This research methodology includes identifying lux value standards, room position, and air exchange standards based on room type. Furthermore, an Android application is created that can calculate the need for lamp brightness and air conditions according to the applicable formula. The calculation results are displayed on an Android application that can be operated via a smart phone. This application was tested in several types of rooms with different conditions. The calculation results on the application are compared with manual calculations and proven to be accurate. This research has successfully created an Android application that can help users to design lighting and air conditioning needs efficiently and effectively.

Abstract

Solar energy has great potential as an alternative energy source in Indonesia, but its application for water pump systems in public facilities such as railway stations remains limited. This study aims to design a solar-powered water pumping system (PATS) to meet the water demands at Kroya Station using PVsyst software. The methodology includes site analysis, calculation of daily water requirements, power estimation, and system simulation using PVsyst. The simulation results indicate that the designed system meets 97.5% of the annual water demand of 2,555,000 liters, with a solar panel efficiency of 80.4% and a pump efficiency of 18.5%. The novelty of this study lies in the design of a PATS system for a railway station using simulation-based analysis with PVsyst—an approach not widely applied in public transportation facilities. These findings offer a technical basis for environmentally friendly and sustainable solar pump system planning.

Abstract

The development of lighting technology, particularly LED lamps, drives the need for light intensity testing (lumen) to ensure quality and energy efficiency. The SNI IEC 62612:2016 standard establishes testing parameters that must be met, but field testing processes are still largely manual and inefficient. This research aims to design and realize an Internet of Things (IoT)-based lamp lumen value testing tool with results displayed on an Android application as a practical and automated solution. The tool is designed according to the SNI IEC 62612:2016 standard, equipped with a BH1750 sensor to measure light intensity (lux), a PZEM-004T sensor to measure voltage and current, and an MLX90614 sensor to measure lamp surface temperature. The testing process is performed automatically using a NodeMCU ESP32 microcontroller, with measurement results displayed on a 20x4 LCD and transmitted to the Blynk application on Android in real-time. Testing on 16 LED lamp samples from various brands and powers showed that the system has high accuracy with average BH1750 sensor accuracy of 98.78%, MLX90614 sensor accuracy of 99.74%, PZEM-004T sensor accuracy for voltage of 99.9% and current 100%, as well as error-free data transmission to Android applications. This tool successfully performs lumen testing automatically, accurately, and efficiently according to national standards.
