Abstract

Any laundry operation will discharge the waste water directly to the water surface, which can lead to pollution in the water. One method that can be used to treat laundry wastewater is a photocatalytic method with TiO2 (Titanium Dioxide) as an UV-assisted catalyst that is combined with a strong H2O2 oxidizer to produce OH (hydroxyl radical) to oxidize pollutants. The study aims to determine the differences in pH, TSS, BOD, COD, and Phosphate separation values with combination of TiO2 and H2O2 doses with variations in UV exposure time for 30, 60, and 90 minutes. A good quality TSS level obtained in the 60th minute with a dose of 1 g TiO2 and in combination with 10 ml H2O2 can reduce TSS levels by 20 mg/l from the initial TSS with a residual weight of 180 mg/L. A decrease in the quality COD level at a 90 minute clearance time with a dosage of 1 gr TiO2, in a combination of 10 ml H2O2, can reduce the COD levels by 32.5 mg/ l from the original COD value of 89.1 mg/l. A reduction in the phosphate level achieved at the cleaning time of 30 minutes at a combined dose of 4 gr TiO2 in a 40 ml combination, can lower the phosphatic level by 0.05 mg /l from the starting value of 5.61 mg/l and already meet the quality standard of laundry waste water.

Abstract

Indonesia is blessed with around 27.510 MWe of geothermal resources. Amongst the numbers, some resources are identified as small-scale geothermal resources. The development of small-scale geothermal resources is quite challenging either to government or private developers due to their low selling price that varies from USD 6.50 cent/kWh to USD 9.76 cent/kWh depending on the location and capacity. The challenges can be multiplied in the case of the electricity produced from a geothermal power plant that located isolated grid, where the electricity is unable to be transmitted to another load areas. Therefore, the electricity production will be limited to only serve the demand in the island that consequently will limit the revenue from electricity sales. This study analyzes the financial aspect of a binary geothermal power plant with gross installed capacity of 5 MW located in isolated island. The analysis shows the power plant will be financially feasible when the electricity selling price is over USD 30 cent/kWh that will generate 12% of IRR which is assumed as feasible target for this project. Furthermore, if environmental benefit is included the project can be feasible at lower selling price of USD 25 cent/kWh.

Abstract

Indonesia, a country highly susceptible to climate change, faces severe water scarcity due to unpredictable rainfall patterns and intensified extreme weather events. This paper presents an innovative solution, the Climate Resilience Water Tank with Rainwater Harvesting and Filtration Technology (CRANK), to address the deepening water scarcity crisis amplified by climate change. CRANK is a sustainable water storage system that integrates rainwater harvesting technology with infiltration wells. The system collects rainwater from rooftops, filters it, and stores it in a tank. When the tank reaches its maximum capacity, the excess rainwater is channeled into infiltration wells where it is filtered and replenishes the groundwater table. This dynamic strategy ensures the optimization of rainwater resources based on local weather dynamics. CRANK is a dependable, sustainable water source for various purposes, including drinking, cooking, and agriculture, and can alleviate the burden on pre-existing water supplies. It also mitigates urban flooding risks by efficiently managing surface water runoff. The feasibility of CRANK is meticulously assessed, including cost of production, profit margin, and operational expenditures, making it an affordable and lucrative solution. The system's target implementation sites are remote villages grappling with severe water scarcity. CRANK represents a significant step towards climate change adaptation and resilience by providing a sustainable, climate-resilient remedy for the water scarcity problem in Indonesia.
