Electrical installations used for more than 50 years often experience a decline in quality and pose various safety risks, such as fires, electric shocks, and damage to electrical equipment. This study aims to analyze the feasibility of electrical installations in residential homes that have been used for more than 50 years, as well as determine the need for revitalization to improve the safety and reliability of the electrical system. The research method was conducted through a quantitative approach with field surveys and technical measurements. Insulation resistance measurements were performed to assess the quality of cable insulation. The collected data includes the physical condition of cables, connectors, protective components, grounding systems, and electrical load distribution. The measurement results before revitalization showed that the insulation resistance values varied between 0.5 MΩ to 0.9 MΩ, all of which were below the minimum feasibility standard of 1 MΩ according to PUIL 2011. After revitalization, the measurement results showed a significant increase with insulation resistance values reaching 2.0 MΩ to 2.5 MΩ, ensuring that all rooms now meet the minimum feasibility standards. These findings emphasize the importance of revitalization to extend the lifespan of electrical installations and reduce safety risks. This research provides practical recommendations for homeowners and electrical technicians to conduct regular inspections and revitalization of aging electrical installations to ensure the safety and efficiency of the electrical system.

In the era of globalization driven by the rapid development of information technology, the adoption of technology in various sectors, including education, has become very urgent. Information technology not only supports the learning process but also optimizes administrative aspects, such as the selection of prospective new students. Manual selection is often slow, error-prone, and non-transparent. Therefore, implementing technology-based systems becomes relevant. Benteng Betawi Middle School is committed to implementing a modern, efficient and transparent selection system using the website-based Simple Additive Weighting (SAW) algorithm. The SAW algorithm, as a simple and effective multi-criteria decision making method, is expected to speed up data processing, increase the accuracy and transparency of selection, and identify the best prospective students. This research aims to design and implement a website-based student selection system using the SAW algorithm at Benteng Betawi Middle School. The steps taken include needs analysis, design, implementation and system evaluation. It is hoped that this system can increase the efficiency, transparency and objectivity of the selection process at Benteng Betawi Middle School and become a reference for other schools that wish to adopt similar technology.

Landscape is a plant maintenance, care and renovation service. In the process of plant care, diligence and consistency are needed in keeping plants alive properly. Problems that are often encountered in this plant care service are less than optimal care including uneven watering of chili plants, this is caused by the watering process which is still done manually without paying attention to soil moisture conditions and temperature at the time of watering. Manual watering can be forgotten or not done by the chili plant nurse and watering is uneven without paying attention to the amount of water needed. Therefore, an automatic plant watering system is needed on a scheduled basis and the volume of watering water is regulated according to soil moisture and air temperature. The research method uses the waterfall method to produce a system that suits user needs. The results of testing the watering system and setting the volume of watering water based on the IoT watering system can work based on input from the humidity sensor and watering schedule obtained from the database with a delay of 1 to 3 seconds and an accuracy level of 90% watering water volume with 10 trials.
