Abstract

This community service project aims to improve the quality of street lighting around the Waringin Tunggal Studio, located in Soneyan Village, Pati Regency. As part of efforts to improve community comfort and safety, this project focuses on addressing the issue of inadequate lighting that can impact community activities, particularly at night. Inadequate lighting around the studio creates discomfort and reduces the sense of security for both studio users and the local community. The project began with a thorough inspection of the lighting conditions around the studio. The next step was to design technical solutions to improve the existing lighting system, including increasing the number of lamps and using more efficient types of lamps in terms of energy consumption and light distribution. Furthermore, good collaboration with village officials and other relevant parties was crucial for the smooth implementation of this project. The improvement process was carried out with a focus on energy efficiency and durability, ensuring long-term benefits. The results of this project showed a significant improvement in the quality and coverage of lighting around the Waringin Tunggal Studio. This improvement not only increased comfort but also increased the sense of security for studio visitors and the surrounding community. Access to the studio at night has become easier and safer, positively impacting the arts and cultural activities held there. A post-event evaluation showed increased community participation in the studio's evening events. This success demonstrates that improved lighting can encourage community participation in community activities. Going forward, it is hoped that this activity can be enhanced by utilizing renewable energy, such as solar power, to ensure optimal lighting even during power outages, thus ensuring the desirability of this activity in the future.

Abstract

An automatic water level controller mechanism in a water tank is needed to maintain the availability of water supply. One way is to create a control system that uses an ultrasonic sensor as a detector of the water level that is fed back to the water tank filling pump. To minimize fluctuations in sensor readings, a mechanism is needed to minimize the occurrence of water ripples. To provide easy information to users on site, a monitoring system in the form of an LED indicator is also added that informs the condition of the water level in the water tank. Therefore, in this study, a tool will be created that can automatically control and monitor the water level based on Arduino Uno which uses an ultrasonic sensor and LED indicator with a wave ripple holder

Abstract

Automatic and adaptive fan speed control is an important aspect in maintaining the stable performance of electronic devices, reducing energy consumption, and preventing damage due to excessive temperature. This research focuses on the design and implementation of a DC fan speed control system that utilizes a temperature sensor in the form of a KSD type thermostat as the main regulator. The system is designed to be able to operate at three different speed levels, which are automatically activated based on certain temperature points, namely 31°C, 40°C, and 55°C. Thus, the fan only works according to actual needs, so its use is more efficient. The research method used is a laboratory experimental approach, which includes three main stages, namely electronic circuit design, hardware component assembly, and functional testing of the system. Trials are carried out to ensure that the system is able to respond to temperature changes appropriately and consistently. The test results show that the control system built works according to the design, where the fan can adjust its rotational speed automatically when the temperature reaches a predetermined threshold. Overall, this system has a simple design, is robust to temperature changes, and is effective in controlling heat in electronic devices. Its implementation has the potential to provide significant benefits in the form of energy efficiency, more optimal fan power utilization, and extended device lifespan through stable operating temperature control. This research could form the basis for the development of smarter and more efficient cooling systems in the future.

Abstract

This research focuses on the design, implementation, and testing of a DC-to-AC inverter circuit utilizing an astable multivibrator configuration. The primary objective of this study is to convert a 12-volt DC input voltage, typically obtained from a battery or other low-voltage sources, into a standard 220-volt AC output voltage suitable for powering common household and industrial appliances. Inverters play a crucial role in power electronics, enabling the efficient use of renewable and portable energy systems. The research method involved several stages, beginning with circuit design based on an astable multivibrator schematic. Components including C1815 and TIP31C transistors, resistors, capacitors, and a step-up transformer were carefully selected and assembled onto a printed circuit board (PCB). After the circuit was successfully constructed, testing was carried out by supplying a 12-volt DC source and measuring the resulting voltage values using a digital multimeter. The experimental results demonstrated that the inverter circuit was able to effectively convert the input voltage into an alternating output, producing an average of 228 volts AC. This indicates that the designed circuit not only functioned according to expectations but also operated with a high degree of accuracy. Overall, the findings highlight the practicality and reliability of the astable multivibrator inverter for low-power conversion applications. Furthermore, the study contributes to a deeper understanding of inverter circuit design and offers a foundation for further development of efficient, low-cost, and accessible power conversion systems.
