Abstract

The purpose of the study are analyzed the potential energy of durian peels as an ingredient of solid fuel use the conversion of biomass hydrothermal technology. This study used an experimental method with hydrothermal treatment. Variations used in this method are temperature variations of 180°C, 200°C, and 220°C with variations in holding times of 30 minutes and 60 minutes. To determine the fuel content of durian peels, heating values and proximate analysis were carried out to determine water content, ash content, volatile content, and carbon content. The test result showed that durian peels waste is suitable to be used as an alternative fuel that is suitable for lignite coal fuel. In testing, the highest calorific value is 4515.52 kal / gram which was equivalent to the calorific value of lignite coal (3500 - 4611 cal / gram) according to the American Standard Testing and Mineral (ASTM).

Abstract

Building plumbing systems have gained increasing scholarly attention alongside the rise of sustainable construction, smart infrastructure, and digital building technologies. This study maps the development of research on building plumbing systems from 2005 to 2025 using an integrated approach combining bibliometric analysis and a systematic literature review. Data were retrieved from the Scopus database using keywords related to plumbing systems, water supply, drainage, smart plumbing, IoT, and digital twin technologies, with article selection conducted through the PRISMA framework. From 1,245 identified records, 612 peer-reviewed journal articles were included in the final analysis. Bibliometric techniques using VOSviewer and Biblioshiny were applied to evaluate publication trends, geographic and institutional contributions, citation performance, and keyword co-occurrence networks. Results indicate a consistent upward trend in publications, rising from 45 articles (2005–2010) to 259 articles (2021–2025). China emerges as the most productive country, while the United States demonstrates the highest citation impact. Keyword analysis reveals three main thematic clusters: water systems, sanitation and drainage, and modern plumbing technologies. The study also identifies key research gaps, including limited integration of artificial intelligence and machine learning, early-stage development of digital twin applications in plumbing systems, and insufficient empirical studies in tropical environments. These findings highlight critical directions for advancing intelligent, efficient, and sustainable plumbing system research
