Abstract

The growing energy demand in the hospitality sector highlights the urgent need for efficient and environmentally friendly renewable energy sources. This study investigates the potential for energy savings in hotel buildings through the implementation of rooftop photovoltaic (PV) systems in Magelang City, with a case study at Atria Hotel. The methodology involved analyzing secondary data on solar energy potential, estimating available rooftop area, simulating PV system capacity, and evaluating energy production and economic savings based on the hotel’s laundry energy requirements. The results indicate that Magelang has substantial solar energy potential, with an average Global Horizontal Irradiance (GHI) exceeding 4.8 kWh/m²/day. At Atria Hotel, a rooftop PV system with a capacity of 4.58 kWp can generate approximately 6,656 kWh of electricity annually, meeting around 25% of the laundry facility’s electricity demand. This implementation translates into annual electricity cost savings of IDR 2,635,136.73. These findings demonstrate that rooftop PV systems represent a strategic solution for enhancing energy efficiency and advancing sustainable hotel development in Magelang City.

Abstract

The existence of home industry plays a very important role in empowering small and medium-sized communities so that they as business actors have independence and self-confidence in entrepreneurship to help the family economy. This Community Service aims to help increase the economic value of small business owners' families by providing kiosks as permanent business premises so that the layout and service are better and compared to previous kiosks/grocery stores which were managed conventionally. The service activities were carried out by the service team together with residents who live in the surrounding areas, starting with conducting site surveys, followed by procurement of row materials in the form of harbel, river sand, cement and lime. Carrying out activities in order to obtain optimal output results, during the activity process stages, assistance is provided with work by the service team starting from preparation for demolition, installation of building foundations, harbel walls, building framework to the finishing process. The impact of good cooperation between partners, the surrounding community and the service team can result in a permanent kiosk building that is suitable, safe and comfortable to be used as a grocery store business to meet the needs of the surrounding residents.
