Abstract

Electrical energy is energy that has an important role for society. One of the benefits is for lighting. The current state of electricity in Indonesia is very concerning, especially since the oil and gas resources on earth are very limited, and one day they will run out. Therefore, various studies have been carried out to find energy sources other than oil and gas, as alternative energy sources that can be utilized according to needs. A water turbine is a device for converting the potential energy of water into mechanical energy. This mechanical energy is then converted into electrical energy by a generator. Hydropower is energy obtained from flowing water. The energy possessed by water can be utilized and used in the form of mechanical energy and electrical energy. Utilization of water energy is mostly done by using waterwheels or water turbines that take advantage of the presence of a waterfall or water flow in the river. The Pelton turbine uses a nozzle with an inner diameter of 4 mm and an angle of 60° capable of producing 0.8031 watts of power. These results were obtained at a discharge variation of 0.0002 m3/second. At the time of this test also which produces the greatest efficiency value among other tests, which is 1.231%.

Abstract

The Bogor City Library plays an important role in creating a strong literacy ecosystem, functioning as a center for community empowerment by providing access to information and skills development. This research aims to analyze circulation patterns and spatial planning in libraries, in order to increase public interest in utilizing existing facilities. Although founded in 1972, the library faced serious challenges, including inadequate space and unattractive facilities, such as a non-functioning multimedia room and a lack of private rooms for discussions. The low literacy rate in Bogor City shows the need for more efforts to increase interest in reading. It is hoped that the "Free Literacy" program can be a solution, but its success is very dependent on library development. By implementing modern architectural designs and innovative elements, libraries can create a comfortable and inspiring learning environment. This research is expected to provide constructive recommendations for developing libraries as effective and inclusive literacy centers. Focusing on the quality of space and human circulation patterns will support optimal visitor experience, making libraries the main pillars in improving literacy and the quality of life of people in the city of Bogor. The synergy between attractive facilities, inspiring space quality, and efficient circulation design will strengthen the role of libraries in social, economic and cultural development.

Abstract

High accident risk in construction projects indicates that OHS documentation alone is insufficient without consistent on-site implementation of safe work procedures. Objective: This study evaluates the implementation of Occupational Health and Safety (OHS) based work procedures and analyzes their impact on the performance of the Construction Safety Management System (CSMS) in the Architectural Christian Center construction project, addressing the gap between administrative and operational compliance. Methodology: An evaluative design with combined descriptive quantitative and qualitative approaches was applied. Data were collected through questionnaires administered to project personnel, field observations, and reviews of OHS-related documents. Analysis compared on-site practices with applicable regulations and the CSMS theoretical framework, supported by interpretation of questionnaire and observation results to identify implementation gaps. Findings: Normatively, OHS-based work procedures meet CSMS documentation requirements; however, operational implementation remains ineffective. Work procedures and Job Safety Analysis (JSA) are still treated primarily as administrative instruments and are not consistently integrated into daily work execution methods. Worker compliance is uneven: PPE use shows relatively better adherence than compliance with work procedures and JSA, indicating that risk control is still oriented toward individual protection rather than optimized through administrative controls and engineering-based work methods. Additionally, positioning OHS personnel within the contractor’s internal organization may reduce the independence and effectiveness of safety supervision due to pressures related to time, cost, and progress targets. Implications: Improving CSMS performance requires stronger integration of work procedures and JSA into routine execution, more consistent enforcement of procedural compliance, and strengthened supervisory authority to reduce reliance on PPE. Originality: This study explicitly links OHS work procedure implementation to CSMS performance while highlighting the contractor-internal OHS organizational structure as a structural factor affecting enforcement effectiveness, and provides actionable recommendations to embed safety within engineering-based construction execution methods.

Abstract

This study compares the effectiveness of conventional water curing and non-woven geotextile membrane curing on concrete compressive strength, an important issue because curing quality strongly influences early hydration and strength development while field constraints often limit continuous water-based curing. A quantitative experimental design was conducted in a controlled laboratory setting using 150 mm concrete cube specimens produced with a standardized mix design; specimens were assigned to either full water immersion or pre-moistened non-woven geotextile membrane curing. Compressive strength data were collected at 7, 14, and 28 days and analyzed descriptively by comparing average strengths and strength development trends between both curing methods. The results show that strength increased with age under both regimes, while membrane curing consistently achieved slightly higher average compressive strength than water curing, with the largest difference at 7 days (28.56 MPa vs. 26.95 MPa) and smaller gaps at 14 days (33.04 MPa vs. 32.58 MPa) and 28 days (38.61 MPa vs. 37.99 MPa). These findings suggest that non-woven geotextile membrane curing can be a practical alternative to water curing, particularly where continuous immersion or water supply is difficult to maintain, because it may provide better early-age moisture retention without compromising later-age strength. The originality of this study lies in presenting direct experimental evidence comparing immersion-based curing and an accessible non-woven geotextile membrane approach across multiple curing ages under consistent specimen production conditions.

Abstract

The dairy industry is very important to the economy, but it has big problems with sustainability since it doesn't use resources well and doesn't handle waste well. Eco-Efficiency (13.1%) and Technical Efficiency (58.7%) are still very low in Serbia because of ongoing structural inefficiencies. In Indonesia, where 90% of dairy farms are operated by smallholders, an estimated 84% of manure is discharged untreated, contributing to greenhouse gas emissions and eutrophication. To solve these problems, we need to use Circular Economy ideas, such as closed-loop nutrient, energy, and water flows and integrated resource recovery. This review evaluates opportunities, sustainability gains, and barriers to implementing closed-loop systems across the dairy supply chain. The objectives include assessing farm-level efficiency, quantifying environmental and economic benefits of manure-derived resource recovery, evaluating circular feed substitution, and analysing biogas adoption barriers among smallholders. The research integrates findings from Stochastic Frontier Analysis, Life Cycle Assessment and Costing, Multi-regional Input–Output analysis, membrane-based water reuse models, and system dynamics, complemented by qualitative surveys of Indonesian farmers. Integrated recovery systems yielded carbon-negative results (up to –1790 kg CO₂ eq/year) and significant economic advantages ($825–$1,056/year). Biogas cut down on the consumption of LPG by about 45%. Circular feeds made more milk and had less of an effect, while treating whey membranes slashed the need for fresh water by 67–90%. Closed-loop solutions make dairy farming much more sustainable, but they need help from policymakers to be able to grow because of high investment costs and ongoing structural inefficiencies.

Abstract

Rapid urbanization in Ternate City has intensified pressure on domestic housing and accelerated changes in traditional dwellings such as Fala Kanci, raising challenges for adaptation without losing cultural identity. Objective: This study investigates how urbanization pressures, socio-economic conditions, and cultural values interact in shaping the spatial, material, and functional transformation of Fala Kanci domestic architecture across different urban contexts in Ternate City. Method: A qualitative approach was applied through field observations, in-depth interviews, questionnaires, and visual documentation of 36 Fala Kanci houses located in interior, peripheral, and urban core zones. Data were examined using thematic and comparative analysis to identify transformation patterns and cross-zone variations. Findings: Transformations occur unevenly. Urban core areas show the most intensive spatial expansion, increased material substitution from organic to industrial components, and broader functional diversification. Peripheral areas display mixed adaptation patterns, while interior areas exhibit stronger intergenerational continuity and greater preservation of traditional forms. Despite extensive physical modification, key cultural values communal interaction, family orientation, and symbolic identity remain embedded in spatial organization and selected architectural elements. Implications: The findings support context-sensitive strategies for architects, planners, and heritage practitioners to balance housing adaptation with cultural continuity in rapidly urbanizing island cities. Originality: This research contributes an integrative household-level account linking urbanization dynamics, socio-economic strategies, and cultural persistence an aspect often underexplored in vernacular architecture and urban studies.
