Abstract

The problem in this thesis research is how to design an Android-Based Community Service Information System at the KalibaMamase Village office. Information Systems for Community Services are based on the system using Black Box Testing and the accuracy of the information system is based on user testing.  The research objective is to design and build a Village-level Community Service Information System in order to improve the quality of services for village staff and the use of services for local villagers.  The benefit obtained from this research is to make a new innovation for each village to be able to facilitate serving residents or residents in the application for letters. This research uses the life cycle model of the Waterfall system development and the design of an Android-based population service information system.  Data collection methods in this study use the method of observation,  interviews,  and data analysis. The conclusion of the research is that the Community Service Information System can facilitate the process of correspondence services in the Village apparatus as well as the use of services for the community in managing population and obtaining information at the Village Office.   In the Android-Based Community Service Information System at the Kaliba Mamase Village Office

Abstract

SMK Negeri 2 Manokwari West Papua Province is one of the vocational high schools that foster 12 competencies in the field of Technology and Engineering with 1,567 people active in 2022. To support daily activities at school, the availability of clean water in the school environment is necessary for washing hands, defecating, and urinating. The availability of clean water is at least balanced with the need for clean water, this is intended to ensure that school needs are fulfilled. This study aims to analyze the need for clean water and clean water quality by quality standards. Clean water needs are analyzed using a mathematical approach based on clean water planning criteria, while the clean water quality analysis is carried out by testing clean water samples through the Manokwari City BPOM laboratory. The results showed that the need for clean water in schools was 17,280 liters/day. Water distribution to bathrooms/toilets, sinks, and public face, uses a piping network sourced from 2 reservoirs with a capacity of 40,400 liters. The source of raw water used is groundwater and pumping systems. For the analysis of clean water quality, the data shows that the temperature parameter = 0.05 oC, pH = 7.88, TDS = 0.3060 mg/L, and coliform number = 27.09 x 10^1 CFU/100 mL, so that the water quality microbiologically does not meet the requirements for sanitary hygiene. While the results of the study showed that the need for clean water in SMK Negeri 2 Manokwari until 2032 reached 33,276 L/day (47.21%). The results of this study are expected to be useful for the development of science for academics in universities, government and society. E, especially for students at SMK Negeri 2 Manokwari, hopefully, it will be interesting reading material in the school library.

Abstract

Aims: This study aims to explore the key issues and potential for implementing Green Infrastructure (GI) in the Tallo River area of Makassar, the largest city in Eastern Indonesia. Given its strategic location near the city center and its extensive undeveloped wetlands, the Tallo River region presents a valuable opportunity for sustainable urban development. The research emphasizes the need for integrated planning that addresses natural, economic, and social dimensions, positioning the Tallo River as a multifunctional resource capable of delivering diverse environmental benefits. Methodology and results: Using Geographic Information Systems (GIS) as a decision support and spatial analysis tool, this study evaluates environmental and socio-economic characteristics of the Tallo River area within the Green Infrastructure framework. Spatial data were analyzed to identify and map existing ecological functions, climate adaptation potential, and flood mitigation capacities. Through this process, various GI components and their functions were classified, and priority zones for Green Infrastructure implementation were delineated based on overlapping environmental and social values. Conclusion, significance and impact study: The findings highlight the critical role of GIS in supporting integrated urban planning and environmental management. Conceptualizing the Tallo River area as a multifunctional green space offers a pathway to enhance ecological resilience, address climate risks, and improve urban livability. This study provides actionable insights for policymakers and urban planners, reinforcing the significance of spatial analysis in guiding sustainable development strategies in rapidly urbanizing regions.

Abstract

Aims: This study aims to investigate the effect of binder variations on the compressive strength of eco paving blocks composed of four layered materials-rice husk, quartz sand, gravel, and activated carbon-each with a thickness of 6 cm. Methodology and results: The application is directed toward wastewater treatment using the rain garden method. Laboratory experiments were conducted to obtain reliable performance data. The results show that cement-bonded paving blocks demonstrate superior performance compared to those using fly ash binders. Cement adhesives ensured strong cohesion between layers, with blocks maintaining integrity during demolding without signs of damage or porosity. In contrast, paving blocks with fly ash binders required longer drying times due to the high moisture absorption of quartz sand, and they exhibited brittleness caused by weak adhesion. Extended curing was necessary before fly ash could adequately bond the base materials. Conclusion, significance and impact study: Quantitative findings revealed that paving blocks with cement adhesives achieved an average compressive strength of 836.25 MPa, higher than the 696.25 MPa of fly ash-bonded blocks. These results imply that cement remains the more effective binder for eco paving blocks in rainwater runoff and wastewater treatment, while fly ash requires optimization to improve its bonding performance. Eco-paving provides a nature-based, sustainable, and cost-effective solution for urban wastewater management, achieving both structural durability and effective pollutant removal.
