Abstract

The need for clean water is one of the essential aspects of community life, especially in areas that are not fully served by the PDAM (Regional Drinking Water Company) distribution network. In Sumber Rejo Subdistrict, particularly in RT 7, the availability of clean water remains a major issue due to the hilly topography, making it difficult for the PDAM pipeline network to reach the area. The local community relies on springs as an alternative water source, which is collected manually without a planned distribution system. This study aims to analyze the potential of the spring in RT 7, Sumber Rejo Subdistrict, as a clean water source based on water quality, flow rate classification, and clean water distribution system planning. The methods used include water quality analysis through laboratory tests covering physical, chemical, and microbiological parameters, flow rate classification based on spring discharge measurements, and distribution system planning using EPANET 2.2 software. The results show that the spring water quality does not fully meet the clean water quality standards according to the Indonesian Ministry of Health Regulation Number 2 of 2023 on Environmental Health, particularly for nitrate, manganese, and aluminum parameters. Based on the flow rate measurements, the spring falls into Class VI, with a flow rate ranging from 0.1 to 1 liter per second, indicating low flow capacity and generally only sufficient to meet water needs on a limited scale (less than 1,000 people). In the clean water distribution network simulation, three alternative distribution scenarios were evaluated, with Alternative 2 showing the most optimal results, with flow velocities ranging from 0.31 to 0.46 m/s

Abstract

The problem of organic waste management in Balikpapan City is increasing, with a total of 193,038 tons/year, 70.3% of which comes from household waste. One solution implemented at Manggar Municipal Solid Waste (MSW) Landfill in Balikpapan is the processing of organic waste using maggots (BSF larvae). This study aims to analyze the current conditions, analyze the factors influencing waste processing, and formulate strategies for optimizing the processing facility. The methods used include quantitative and qualitative approaches, as well as best practice analysis as a basis for improvement. The research findings highlight several issues, such as the absence of BSF egg weighing, predator disturbances in the fly cages, biopon systems without drainage channels, and the manual process of separating maggots from casings. Optimization was carried out through the redesign of the BSF fly enclosure, improvement, and addition of 21 biopon units, which can produce 35.7 liters of liquid organic fertilizer (POC) and decompose 1,0878 tons of organic waste per cycle, the design of a sieving machine, and the reorganization of the maggot house layout. These efforts are expected to enhance processing efficiency and capacity to 1,0878 tons per cycle, supporting more sustainable and environmentally friendly waste management.

Abstract

Population growth that is not balanced with adequate environmental management can hurt environmental quality. The Somber Hulu River is one of the rivers located in the North Balikpapan District. Some people living around the river directly discharge liquid waste into the river, potentially causing pollution that can disrupt the river ecosystem. One sign of pollution in the Somber Hulu River is characterized by smelly and cloudy river water. The research began by determining the river water sampling point, and then the water samples were tested to determine the pollutant concentration based on the specified parameters. The next stage was determining the water quality status using the Pollution Index (IP) method. The reference water quality standard used the class II river water quality standard based on Government Regulation number 22 of 2021. The purpose of this study was to determine the water quality status in the Somber Hulu River as a basis for decision-making in planning control measures to improve surface water quality. Based on the results of the measurements carried out, it is known that in general the water quality of the Somber Hulu River is moderately polluted with an IP value of 3.87 and lightly polluted with an IP value of 7.05 at point 2, an IP value of 5.37 at point 3, and an IP value of 5.25 at point 4. There needs to be management and control of water pollution sources, such as optimizing the use of septic tanks, carrying out monitoring activities, conducting routine river water quality monitoring, and encouraging community involvement in sustainable river management.

Abstract

Kebutuhan energi fosil terus meningkat seiring pertumbuhan penduduk dan perkembangan industri, sehingga diperlukan sumber energi alternatif yang lebih berkelanjutan. Penelitian ini bertujuan menganalisis karakteristik briket arang berbahan baku limbah bambu dan tongkol jagung dengan perekat tepung tapioka serta menentukan komposisi optimum yang memenuhi standar mutu. Briket dibuat dengan variasi komposisi limbah bambu jagung sebesar 90:0:10, 80:10:10, 70:20:10, 60:30:10, dan 50:40:10. Karakteristik yang diuji meliputi kadar air, kadar abu, kadar zat menguap, kadar karbon terikat, dan nilai kalor berdasarkan SNI 01-6235-2000. Hasil penelitian menunjukkan bahwa komposisi 50:40:10 merupakan komposisi terbaik dengan kadar air 7,10%, kadar abu 2,96%, dan nilai kalor 6.305,62 kal/g yang telah memenuhi standar SNI. Namun, kadar zat menguap sebesar 39,27% dan karbon terikat sebesar 50,67% masih belum memenuhi persyaratan standar. Dengan demikian, limbah bambu dan tongkol jagung berpotensi dimanfaatkan sebagai bahan baku briket alternatif, meskipun diperlukan optimasi proses untuk meningkatkan kualitas produk.
