The purpose of this study is to calculate qualitative erosion with digital analysis of satellite imagery in Subwatershed Tulis. Planning for a watershed for the long term requires the calculation of qualitative erosion values that are accurate and spread evenly to each land unit. This study uses digital analysis methods by relying on the digital value of each pixel that can be performed mathematically. Satellite images used are Landsat TM 8 images on October 31, 2016, and a radar image is SRTM (Shuttle Radar Topography Mission). The analysis was carried out by calculating each of the factors causing erosion in the form of drainage maps, aspect maps, slope maps, texture maps, and land cover maps. Each factor was given a score or score from 1 to 3, namely low (1), medium (2) and high (3), so that after being calculated by the method of SES (Soil Erosion Status) it became light level erosion (1) <50, medium (2 ) = 50-100 and weight (3)> 100 tons/ha/ year. The results of the calculation of qualitative erosion in Sub-watershed Tulis which has an area of 12,750 ha, obtained light erosion 4% (529 ha), medium 85% (10,781 ha), and weight 11% (1,440 ha).

Urea-hydroxyapatite can be used as fertilizer which was efficient and environmentally friendly. The variation of Ca(OH)2 in the urea-hydroxyapatite’s synthesis and its characterization would provide information for manufacturing slow release fertilizer. The material used were urea (99.5 %); Ca(OH)2; H3PO4 0.67 M and distilled water. The synthesis technique used in this study is bottom-up with Ca(OH)2 variation of 6, 8, 10 and 12 grams. The results of the synthesis with 6 grams of Ca(OH)2 was not able to produce sediment powder. The results of the Scanning Electron Microscopy (SEM) showed that the urea packaging with hydroxyapatite was better for variations of Ca(OH)2 8 grams and 10 grams. The results of the Energy Dispersive X-Ray Spectrometry (EDX) showed more elemental composition in the variation of Ca(OH)2 8 grams and 10 grams which were 35.7 Wt% and 40.4 Wt%. The results of the Fourier Transform Infrared Spectrometer (FTIR) showed that the variation of Ca(OH)2 8 gram has a good bonding of urea and hydroxyapatite. The Particle Size Analyzer (PSA) measurement for all samples of urea-hydroxyapatite yielded the particle size of about 0.5–2.5 mm and 10–15 mm for urea and hydroxyapatite, respectively. As a conclusion, the variation of Ca(OH)2 8 grams could be recommended as a reference in the composition of urea-hydroxyapatite fabrication for slow release fertilizer.

This study analyzes the level and status of greenhouse gas emissions or removals from solid waste management activities in Marabahan Subdistrict, Formulates an action plan for solid waste management that is low in Greenhouse Gas emissions in Marabahan Subdistrict and Projects the level and status of emissions or Greenhouse Gas absorption from waste management solid in Marabahan District until 2030, according to the 2006 IPCC BAU scenario and mitigation actions. The waste sector greenhouse gas emissions inventory results in 2016 reached 5.16 Gg CO2-eq. However, due to improvements in domestic waste management, the 2016 greenhouse gas emissions rate was reduced by 11.1% compared to the BAU scenario. In 2016, waste sector greenhouse gas emissions in the BAU scenario are projected to reach 10.61 Gg CO2-eq, and will continue to grow until 2020 to 11.14 Gg CO2-eq, and in 2030 to 12.64 Gg CO2-eq. In Action Mitigation I waste management is carried out in the community by implementing methane recovery in the waste banks and TPS 3R. In Action Mitigation II, waste management is carried out at the Final Processing Site (TPA) carried out by the local government to handle it. When compared to the BAU scenario, the design of mitigation actions I and II in the context of reducing greenhouse gas emissions resulted in a decrease of 35.2%, 59.5% and 98.3% in 2013, 2020 and 2030.
