Ngurah Rai Forest Park, is one of the remaining mangrove ecosystems located in the Benoa Bali Bay, Indonesia. Ecosystem in this forest park is threathened due to the construction of Bali Mandara Highway. This study was conducted to determine the impact of the construction of the Bali Mandara Highway to the mangrove ecosystem in Ngurah Rai Forest Park. In this study, qualitative method was applied in order to compare the environmental parameter of mangrove ecosystem before and after construction of the highway. The construction of the Bali Mandara Highway affects several physical parameters of the mangrove ecosystem. The salinity, pH value and DO content are physical parameters which decreasing after the contruction. The decreasing also identified for current velocity, during the high tide current velocity decline to 0 - 0.44 m/s while during the low tide it goes down to 0 - 0.84 m/s. On the other hand, sedimentation area increases by 485.62 ha which causes silting. The vegetation analysis shows that Bali Mandara Highway has no significant impact to the diversity of mangrove species in Ngurah Rai Forest Park. Sonneratia alba still dominate the mangrove vegetation in those area.

The decline of green open space and uneven water distribution resulted in limited access to clean water in Tihingan Village, Banjarangkan District, Klungkung Regency. This condition poses challenges for fulfilling the community’s basic needs for consumption and hygiene-sanitation. Communal Rainwater Harvesting Installation (Instalasi Pemanenan Air Hujan/IPAH) is proposed as a strategic alternative of appropriate technology in clean water provision. Raw rainwater often does not meet clean water standards, thus requiring an effective and affordable filtration process. This study aims to analyze the performance of charcoal and palm fiber filtration media in improving the quality of harvested rainwater in communal IPAH to meet Class I clean water standards. A descriptive-comparative method with an experimental laboratory approach was employed. Rainwater samples were collected before (influent) and after filtration (effluent). Tested parameters included pH, Escherichia coli content, Total Suspended Solids (TSS), and ammonia (NH₃). The filtration media consisted of a combination of locally sourced charcoal and palm fiber. Results showed that the filtration effectively reduced TSS, decreased E. coli content to meet quality standards, and lowered ammonia to safe levels, with improved pH levels. The water quality after filtration complied with Class I clean water standards and was suitable for hygiene and sanitation purposes. This system proved effective, inexpensive, environmentally friendly, and supported sustainable clean water provision while providing local economic benefits. Filtration using charcoal and palm fiber media can be a practical and replicable model to provide clean water in similar regions.

Tomuan Pane Hamlet in Simalungun Regency, North Sumatra, faces critical challenges in drinking water provision due to the absence of a household water distribution network. Additionally, water quality tests revealed phosphate and total coliform contamination levels exceeding the drinking water standards set by the Indonesian Ministry of Health Regulation No. 2 of 2023. The contamination is attributed to nearby agricultural activities and poorly maintained environmental infrastructure. This study aims to design a simple, community-based water distribution and treatment system (Penyediaan Air Minum Berbasis Masyarakat: PAMBM). Water demand projections were calculated using three population growth methods: arithmetic, geometric, and least square approaches. The distribution network was simulated using EPANET 2.2 software. The water treatment system was designed utilizing simple filtration tailored to local conditions. Population projections indicate that water demand in 2040 will reach 0.88 L/s. The proposed treatment system consists of two filtration stages: a 1.2-meter downflow reactor of 67% zeolite, 8% sand, 8% activated carbon media, and a 2-meter upflow reactor of 21% zeolite, 21% gravel, 27% activated carbon, and 21% sand media:. The combined system effectively reduced phosphate concentrations by 49.39% and completely eliminated total coliforms (100% removal). The distribution network simulation produced an average flow velocity of 0.71 m/s using a 5 cm transmission pipe and a 4 cm main distribution pipe.

Canang waste, a type of organic waste from Balinese Hindu offerings, is commonly produced in traditional villages such as Desa Tihingan. This study aims to utilize canang waste as raw material for briquette production. The method employed is experimental, involving stages such as material collection, drying, shredding, carbonization, sieving, mixing, molding, and drying. Samples were tested using a bomb calorimeter to determine their Higher Heating Value (HHV) and Lower Heating Value (LHV). The results showed that canang briquettes have an HHV of 21.27 MJ/kg and an LHV of 19.64 MJ/kg, which are higher than those of mixed organic briquettes (HHV: 20.62 MJ/kg, LHV: 18.47 MJ/kg), but lower than prapen charcoal (HHV: 26.95 MJ/kg, LHV: 25.82 MJ/kg). These findings indicate that canang briquettes have potential as a viable alternative fuel. Moreover, this approach offers an environmentally friendly and sustainable solution for managing ceremonial waste.
