Abstract

Open spaces have been a key feature of mosques since the first Nabawiy Mosque was built during the time of the Prophet Muhammad. Fourteen centuries have passed, and mosques have evolved in accordance with their surroundings, with open spaces not always being a key feature of mosques. The issue of mosque designs that tend to be exclusive is an important reason for reviving the inclusive nature of mosques as in the time of the Prophet (peace be upon him). This paper aims to review the role of open spaces in mosques in meeting the needs of the wider community, including various age groups and socioeconomic strata, and even non-Muslims. This paper also puts forward an idea for integrating open spaces into mosque design for Generation Z. This generation, with its unique characteristics, is expected to play an increasingly important role in revitalizing mosques. This study adopts a mixed-methods research-by-design (RBD) framework, combining a qualitative historical and literature synthesis, exploratory precedent case studies, and a quantitative user preference survey involving 100 Muslim Generation Z respondents (N = 100) in Medan, Indonesia. The findings from these methods were integrated to formulate design ideas for inclusive mosque open spaces that respond to the needs and preferences of Generation Z. This study shows that open spaces are an important key feature for inclusive mosques that are in line with the needs of Generation Z, who are open-minded towards advances in information and developments in thought, art, science, and technology. The concept of inclusive mosque design for Generation Z offers open spaces that are integrated with urban spaces and directly connected to mosques structurally, functionally, and visually, where social activities become a showcase for mosque activities.

Abstract

Solar photovoltaic (PV) power and battery storage can reduce the use of fossil-derived electricity aboard short-sea ships, but their performance depends on deck area, weather, demand profiles, charging infrastructure and marine safety requirements. This article develops an evidence-informed conceptual architecture for Solar Energy Ships (SES) serving Indonesian archipelagic routes. Official Statistics Indonesia (BPS) Sea Transportation Statistics publications for 2021–2024 provide the traceable transport-data context, while peer-reviewed studies underpin the engineering approach. The proposed system combines a candidate 150–300 kWp PV array, lithium-iron-phosphate battery storage, DC conversion, maximum power point tracking (MPPT) and supervisory energy management. A transparent illustrative sensitivity calculation, assuming daily equivalent solar irradiation of 4–6 kWh/m² and a performance ratio of 0.75, gives 450–675 kWh/day for 150 kWp and 900–1,350 kWh/day for 300 kWp. These values are scenario calculations, not Indonesian route measurements. The original manuscript’s claims concerning 98.7% MPPT efficiency, 100% auxiliary-load coverage, emission reduction and payback cannot be confirmed without experimental logs and reproducible input data. The study therefore identifies a technically relevant research design and explicit requirements for future field validation rather than claiming measured SES effectiveness.

Abstract

Autonomous electric ships (AES) combine battery-electric propulsion with advanced navigation and shore-side supervision. This paper develops a source-traceable conceptual screening framework for their potential deployment on Indonesian inter-island routes. The analysis is based on the published scope of Statistics Indonesia (BPS) Sea Transportation Statistics for 2021–2024, International Maritime Organization (IMO) instruments on greenhouse gases, maritime autonomous surface ships (MASS), and collision prevention, together with peer-reviewed studies of autonomous navigation and ship electrification. A proposed four-layer architecture links battery and propulsion safety, multimodal perception and COLREGs decision support, resilient communications, and human-supervised shore services. The assessment specifies indicators needed for corridor selection and equations for future energy, well-to-wake emissions, and cost comparisons. It does not report measured AES emissions, economic payback, collision-avoidance performance, or route-specific battery sizing, because the corresponding engineering logs and test datasets were not supplied. The contribution is a transparent design and validation agenda rather than a completed technology demonstration
