Is Geothermal Power Plant (PLTP) on Mount Slamet Necessary?

This article intends to reflect on the construction of a Geothermal Power Plant (PLTP) on Mount Slamet. The construction of the PLTP has been rejected by the Banyumas community, especially the slope communities there. During the exploration process for the power plant, the people on the slopes of Mount Slamet experienced various impacts. Starting from the murky water, forest animals entering the villages, so that material losses cannot do business. This article reviews the phenomenology of how important the development of PLTP is in the midst of a surplus of electricity in Java Island. The findings in this article identify flaws in procedures from planning to implementation. The plan is to do legal acrobatics so that it is easy to get project permits. When doing exploration, it has a significant impact on the community on the slopes of Mount Slamet. Therefore the article tries to provide suggestions or input to local and central governments for; make an objective Environmental Impact Analysis (AMDAL), involve professional parties to conduct academic studies, involve the community or NGOs when determining the PLTP project, conduct intensive and periodic outreach to the community, and provide compensation to the affected communities.

Geothermal Power

Geothermal potential in Indonesia estimate can produced renewable energy 29 GW, and until 2016 it still used 5% or about 1643 MW in. From that result, about 227 MW produced by Wayang Windu geothermal power plant. The Input were raw material, energy and water. These input produced electricity as main product, by product, and also other output that related to environment i.e. emission, solid waste and waste water. All environmental impacts should be controlled to comply with environmental standard, and even go beyond compliance and perform continual improvement. This research will use Life Cycle Assessment method based on ISO 14040 and use cradle to gate concept with boundary from liquid steam production until electricity produced, and Megawatt Hours as the functional unit. Life Cycle Inventory has been done with direct input and output in the boundary and resulted that subsystem of Non Condensable Gas and condensate production have the largest environmental impact. LCI also show that every MWh electricity produced, it needed 6.87 Ton dry steam or 8.16 Ton liquid steam. Global Warming Potential (GWP) value is 0.155 Ton CO2eq./MWh, Acidification Potential (AP) 1.69 kg SO2eq./MWh, Eutrophication Potential (EP) 5.36 gPO4 eq./MWh and land use impacts 0.000024 PDF/m2. Life Cycle Impact Assessment resulted that AP contribute 78% of environmental impact and 98% resulted from H2S Non Condensable Gas. Comparison results with another dry steam geothermal power plant show that impact potential result of the company in good position and there’s a strong relation between gross production, GWP and AP value.Keywords: Life cycle assessment; Geothermal; Continual Improvement; Global Warming Potential; Acidification Potential
