Abstract

Public and religious facilities, like mosques, often suffer from substantial energy waste due to large physical footprints, manual control, and highly intermittent, non-linear occupancy patterns. This chronic inefficiency results in high utility bills, diverting scarce community funds away from core charitable and social welfare missions, underscoring the necessity for advanced, cost-effective automation. This study aims to design and empirically validate the “Smart Mosque Architecture,” an integrated Internet of Things (IoT) system utilizing a novel Dynamic Prayer Time-Based Control Algorithm (DPT-BCA) to proactively optimize energy consumption across lighting and HVAC systems. A quantitative, quasi-experimental time-series analysis was conducted over a six-month experimental period, comparing the system’s performance against a four-month manual control baseline. The custom low-cost system achieved a statistically significant average monthly energy reduction of 30.0% (p < 0.001), driven primarily by a 47.4% reduction in HVAC runtime. Financial analysis confirmed the system’s economic viability, yielding a simple Return on Investment (ROI) in just eighteen months. The Smart Mosque Architecture is a robust and superior predictive control solution for religious facilities. The DPT-BCA successfully maximizes energy efficiency and service quality, establishing a scalable, ethical blueprint for sustainable institutional facility management worldwide.

Abstract

Recycled aluminum–silicon (Al–Si) alloys produced from remelted automotive pistons are increasingly utilized in the casting industry because of their cost-effectiveness, recyclability, and environmental benefits. However, the remelting process may degrade material quality through microstructural changes, porosity formation, and deterioration of mechanical properties. Studies investigating the influence of different quenching media on remelted Al–Si piston alloys remain limited. The novelty of this study lies in evaluating the relationship between quenching media, microstructural evolution, and hardness characteristics of remelted Al–Si piston alloys. This study aimed to investigate the effect of different quenching media after solution treatment on the hardness and microstructure of remelted Al–Si alloys. Used automotive pistons were remelted, cast into metal molds, and machined into standard test specimens. The specimens were heated from room temperature to 550 °C in approximately 30 min, held at 550 °C for 90 min, and quenched in water, oil, or air. Hardness was evaluated using the Brinell hardness test, while the microstructure was examined by optical microscopy. The highest hardness was obtained in the specimen without quenching (63.3 HB), followed by water quenching (62.6 HB), oil quenching (59.6 HB), and air cooling (51.6 HB). Water quenching produced a finer and more homogeneous distribution of silicon particles than oil and air cooling. These findings provide a scientific basis for selecting an appropriate quenching medium to optimize the heat treatment of recycled Al–Si alloys for sustainable casting applications.

Abstract

Peningkatan volume limbah medis di kabupaten Pemalang menuntut penanganan yang terstandardisasi guna memitigasi risiko pencemaran lingkungan dan transmisi penyakit infeksius. Pengabdian ini bertujuan meningkatkan kapasitas manajerial dan keterampilan teknis para fasilitator kesehatan dalam mengelola residu klinis secara aman serta bernilai guna. Program kemitraan ini melibatkan 30 fasilitator dari berbagai fasilitas pelayanan kesehatan di wilayah tersebut sebagai mitra strategis. Metode pelaksanaan mengadopsi pendekatan Action Research yang meliputi tahapan survei lapangan, lokakarya interaktif berbasis pola edupreneur, serta pendampingan teknis secara luring. Hasil kegiatan menunjukkan lonjakan signifikan pada literasi regulatif dan kompetensi psikomotorik peserta dalam memilah serta mensterilisasi limbah sesuai protokol biosekuriti terkini. Temuan ini menegaskan bahwa integrasi aspek kewirausahaan dalam manajemen lingkungan mampu mengubah persepsi terhadap limbah dari beban operasional menjadi entitas produktif. Maknanya, penguatan kapasitas SDM merupakan determinan utama dalam menciptakan resiliensi tata kelola lingkungan hidup di sektor kesehatan. Keberhasilan ini memiliki urgensi tinggi sebagai model prototipe bagi standardisasi pengelolaan limbah medis yang berkelanjutan dan aman di tingkat lokal maupun nasional.
