Abstract

This study examines the implementation of LOSIDA (Lodong Sisa Dapur), an integrated organic waste management system, at Muhammadiyah University of Sorong. The research employs a quantitative experimental approach, focusing on system design evaluation, composting process analysis, and end-product characterization. The LOSIDA system, constructed using 4-inch PVC pipes with strategic aeration holes, demonstrates effective conversion of household organic waste into quality compost over a three-month period. The integration of the composting system with planting media creates an efficient closed nutrient cycle, enabling direct utilization of decomposition products. Results indicate successful organic matter degradation with optimal C/N ratio management (25:1) and proper aeration control. The final compost exhibits desirable physical characteristics, including homogeneous crumbly texture and dark brown coloration, indicating proper humus content. This research validates LOSIDA as a practical solution for sustainable household organic waste management in urban areas.

Abstract

This research aims to design and evaluate a stacked bucket system as a simple solution for managing household organic waste. The research method was carried out experimentally with a quantitative approach, involving the stages of preparation, manufacture and evaluation of the use of stacked buckets. The research results showed that the stacked bucket design equipped with a hole in the bottom and a tap to drain the leachate could function well. However, the success of this system was disrupted by failures in the composting process due to the condition of the organic waste being too dry and the lack of routine checks during fermentation. However, this research succeeded in identifying important factors such as humidity and the use of EM4 fluid to support the activity of microorganisms in the decomposition process. With further optimization, stacked buckets have the potential to become an effective, environmentally friendly and sustainable organic waste management method.

Abstract

This research aimed to analyze the quality of borewell water widely utilized by the community on Jalan Pendidikan KM 8, Malaingkedi, Sorong Manoi District, Sorong City, West Papua. Water samples were collected at three different times, namely 09.00, 14.00, and 17.00. The parameters tested included physical parameters such as color, odor, TDS (Total Dissolved Solids), conductivity, salinity and chemical parameters such as pH. The results showed that in general, the quality of the borewell water still met the quality standards for clean water according to the Indonesian Ministry of Health Regulation No. 32 of 2017. The average values were 315.67 μS/cm for conductivity, 207 ppm for TDS, 157 ppm for salinity, and 8.47 for pH. There were variations in the values for each tested parameter, but they were still within the permitted range. However, some parameters such as slightly turbid water color and pH values slightly exceeding the ideal range were observed. Regular water quality monitoring and pollution control efforts are essential to ensure the availability of safe clean water for the community.

Abstract

Penelitian ini mengevaluasi manfaat green roof dalam manajemen air hujan dan mitigasi urban heatisland effect di Singapura. Sistem green roof test bed yang diuji terdiri dari 3 unit, di mana 2 unitberupa atap vegetasi dan 1 unit atap tanpa vegetasi sebagai kontrol. Hasil menunjukkan green roofdapat secara signifikan menurunkan suhu permukaan atap hingga 7,3°C dan suhu udara sekitarhingga 0,5°C dibandingkan atap tanpa vegetasi pada siang hari. Untuk curah hujan 18 mm, greenroof dapat mengurangi puncak limpasan dan menunda puncak limpasan.

Abstract

This study examines the effectiveness of a simple water filtration system using a combination of natural media and coagulants. The filter system comprises coconut fiber, coastal sand, zeolite, activated carbon, wood charcoal, gravel, and coral fragments. Alum and Moringa seeds were tested as coagulants. The filtration process demonstrated a reduction in turbidity from >1000 NTU to 6.94 NTU and pH normalization from 8.3 to 6.9. However, increases in TDS and conductivity were observed. Post-filtration coagulant application yielded varied results, with Moringa seeds showing greater potential in maintaining pH and water clarity compared to alum. Although some parameters such as pH, TDS, and temperature met clean water standards after treatment, high TSS (>1000 mg/L) and turbidity (72.5-270 NTU) levels indicate the need for further optimization. This research highlights both the potential and challenges in developing water treatment systems based on local resources, as well as the importance of adjusting settling time and coagulant dosage to enhance the quality of treated water.
