Water quality in areas around Galuga Landfill, Bogor Regency, West Java

The research is aimed to analyze leachate, surface water and ground water characteristics around Galuga landfill site, Bogor District. Water samples had been taken in dry season of 2014 and in the end of rainy season of 2015 from several sites in areas around Galuga landfills which included leachate water, surface water, and ground water. Leachate, surface water and ground water had temperature and pH in normal ranges; whereas nitrate and Pb contents were high to very high levels, especially in site adjacent to waste piles. The concentrations decreased in line with increasing distance from waste piles. Higher content of nitrate in leachate occurred in dry season, but in well water it was found in rainy season. Meanwhile, Pb content in well water were high, both in dry and rainy seasons. Concentrations of nitrate and Pb in leachate water were higher than wastewater quality standard, so that the leachate water were not safe to be discharged directly to natural water body. The high content of nitrate and Pb caused the well water unsuitable to be consumed without water treatment processing.

Spatial Distribution and Landscape Characteristics of Flores Hawk-Eagle (Nisaetus Floris) Habitat in Flores Island

Flores Hawk-Eagle (FHE, Nisaetus floris) is one of the endemic and keystone species that was rarely studied among other eagles. The study on the FHE is currently experiencing limited information for estimating their distribution area. Therefore, the FHE habitat distribution is required as the essential information for developing the strategies and conservation action. The objectives of this study were to identify the spatial habitat distribution and analyze the characteristics of the habitat. Minimum convex polygon (MCP) and kernel-density estimation (KDE) 95% was combined with the land cover map for delineating the patch habitat of FHE. Slope, elevation, and land cover were used as environmental variables. Principal Component Analysis (PCA) combine with GIS were used for characterizing the landscape habitat. The results showed that there were eight habitat patches with a total area of 1.132 km2. Six principal components were retained from PCA analysis which explained 71.96% of data variance. Habitat characteristics of FHE describe its requirement for nesting and hunting activities for principal components 1 to 4, while for flight activity related to principal components 5 and 6. Forests and savannahs become the main habitat preference for both nesting and hunting activities. Results of this study will be supported as baseline information for developing conservation strategies and action for FHE.

Monitoring Slope Creep Motion using Multi Temporal Interferometry Synthetic Aperture Radar in Semarang, Indonesia

Landslide is one type of slope movement, where the slope movement includes creep. Although creep movement does not have an impact on the risk of loss of life, this creep movement takes place constantly and invisible which has an impact on economic losses. In this study, a time-series monitoring was carried out from 2018 to 2020 to see the movement of the slopes in the study area using the Multi-Temporal Interferometry Synthetic Aperture Radar (MTInSAR). A time series method from Sentinel 1A/B data, which includes Trangkil Sejahtera Housing (PTS), Soegijapranata Catholic University (UNIKA), and 17 August 1945 University (UNTAG) in Semarang City, Indonesia. The results of data processing indicate that there are slope movement in the target location, namely Trangkil Sejahtera and Selorejo Housing (southwest of UNIKA). Based on BPBD 2021 data, landslides occurred in the Trangkil Baru Housing Center (to the north of PTS) and the Garang River landslide channel west of Selorejo. This shows that there is a link between crawling in 2018-2020 and landslides in 2021. Although the use of satellite data has some drawbacks, the results can be taken into consideration in building an early warning system and reducing losses due to landslides.

Institutional Analysis of Protection Forest Area Land Use Pattern in the North Bandung Area, Bandung Regency

Land use degradation has always been a problem for forest areas. Numerous past studies have investigated that there are patterns in the forest area's land use management that support forest sustainability and society's economy. This research aims to identify the action arena and patterns of interaction, to describe the outcomes of the two land use patterns, and to formulate the strategy related to forest area land use pattern in North Bandung Area, Bandung Regency. This research used Institutional analysis and development (IAD) framework as the research method. The identified action arena includes the pattern of commodity and profession transfer. The actors involved were State-owned Forest Enterprises (Perum Perhutani), Village Administrations, forest extensions, Forest Village Community Association (FVCA), and Forest and Farm Producers Organization (FFPO). The most dominating actor in land use activities in both patterns was Perum Perhutani, along with FVCA and FFPO. The pattern of interaction that exists between actors was prospering with only minor problems found within its coordination system. The outcome of the application of these two patterns, among others, is to raise public awareness in conserving forests and improving the community's economy.
