Mount Lokon is an active mountain near residential areas such as cities Tomohon, Tondano, and Manado. Along with the increasing population and population development around Mount Lokon, vegetation is decreasing due to converting land from grassland to land use for human activities. Using Landsat 8 OLI/TIRS images, this study was conducted to analyze the surface temperature and vegetation index dynamics around Mount Lokon, including the residential areas. Found that an increase in mean temperature occurred, and the peak increased dramatically in 2018 with temperatures > 26˚C. This result, of course, correlates with the decreasing vegetation area. However, the decline occurred in 2020 due to decreased human activities and land clearing for new settlements caused by activity restrictions which were the effects of the COVID-19 pandemic. Reforestation efforts must be made to increase the vegetation around Mount Lokon, including residential areas. The average surface temperature can be controlled, and living creatures can be given comfort to living things around them even after the pandemic and human activities return to normal.

The application of geospatial analysis is a need to respond to the increasing number of social conflicts caused by the existence of public places of worships (PPW) in Indonesia. This conflict eventually becomes endemic among Indonesian cross-cultural society. Even though the government has produced a regulation-like policy namely SKB 2006 to manage the establishment of PPW, its contribution to avoiding or reducing the conflicts is in question. Researchers notice that the policy is misused in some incidents to even trigger the conflict. It is due to the presence of people participation defined in SKB 2006 particularly to determine the legalization of PPW. Currently there is no exact foundation used by the government to precisely measure the status of PPW, hence the decision to permit or reject any proposal to establish PPW is determined by the acceptance of surrounding society which in many occasions becomes the cause of the conflict. Therefore the government needs to regain control over the existence of PPW since these types of buildings are public facilities used by people in cross-cultural society. The research is to provide accurate information regarding the existence of PPW and the impact of their presence using geospatial analysis. The objective is to analyze the interaction between PPW and its surrounding objects. The analysis is based on PPW coverage, overlapping and blank spot area. A case study has been conducted to analyze the existence of PPW at Cemorokandang village, a part of Malang city in the province of East Java. The application highlights the issue of overwhelming PPW in the location of analysis.

Bamboo reinforced concrete as a building material is expected to be an alternative to steel reinforced concrete. Due to the fact that steel is not renewable and polluting steel mills are fairly high. The bond strength is a major concern for the natural fiber used as reinforcement in structural composites. This paper reports study on the bond strength of bamboo reinforcement in concrete, to determine the adhesion reinforcement in concrete often do by the pull-out test. The research objective was bond strength of lightweight concrete and bamboo reinforcement. The test used light weight concrete with foam additives klerak. Bamboo slats were coated with paint and sprinkled with sand. The results obtained showed that the bond strength bamboo 60% of the bond strength steel.
