Abstract

Clean water supply is one of the strategic issues in Bima City which is of concern and is stated in the Bima City RPJMD. The main problem with providing clean water in Bima City is the crisis that occurs when the dry season arrives. Apart from that, if we follow the projected population growth of Bima City, the amount of raw water that is available and can be used as a source of clean water will not be able to meet the needs of the population in the future, so another alternative source is needed, namely by utilizing groundwater. This research aims to spatially see the groundwater potential in the Rontu watershed located in Bima City and measure projected water use needs in the Bima City area. The method used is spatial analysis with quantitative methods Multi Criteria Evaluation (MCE), Groundwater Potential Index (GWPI), and the Thornthwaite method for determining areas that have the potential to have groundwater. The research uses the help of a geographic information system (GIS) and remote sensing data to produce a groundwater potential zone map. Based on the results of the groundwater potential zoning map created, it can be seen that the Rontu watershed area as a whole and Bima City tend to have very high potential for groundwater storage and supply. This research also provides an overview of water use in both the domestic and non-domestic sectors in the Rontu Watershed area which includes Bima City and calculates the remaining water reserves from the results of water use and water supply obtained in the Rontu Watershed area, so that it can provide recommendations. for future water supply.

Abstract

This research aims to: analyze built-up area, rainfall potential, and the effort of groundwater conservation in the Ci Hideung watershed. An experimental method was done to discover the depth of groundwater. Landsat 8 Images are used to analyze the land cover. Rainfall volume is measured by formula; V = Rainfall.area, while the infiltration wells using formula: V = volume (m3).area. The infiltration measurement uses a double ring infiltrometer. Built-up land area are 1.563 km2 (14.77 %) and non built-up area are 9.022km2(85.27 %). The lowest rainfall potential to be absorbed is in May with a volume of 0.282 m3, while the highest is in November with a thickness of 2.912 m. Rainfall volume needs to be absorbed through the infiltration wells on the smallest land unit every 100 m2. The highest rainfall thickness is 2.912, then the volume of 302.40 mm3 was added to the infiltration wells with a length of 1 meter and a wide of 1 meter with a depth of 2.912 meters. Groundwater conservation is highly needed to increase groundwater supply. The highest rainfall volume of 302.40 mm3 could be absorbed in 2.91 hours (174.46 minutes) and the longest is in 3.64 hours. The infiltration wells have a role in storing rainfall to increase groundwater supply so that groundwater surface is also increased.

Abstract

Kecamatan Kertasari merupakan wilayah dengan lahan kritis terluas di Kabupaten Bandung. Lahan kritis disebabkan oleh faktor seperti kerapatan vegetasi sangat buruk, kemiringan lereng sangat curam, dan erosi sangat berat. Tujuan utama penelitian ini adalah menganalisis identifikasi dan klasifikasi lahan kritis menggunakan fuzzy logic untuk direkomendasikan dengan teknologi agroforestri sebagai upaya rehabilitasi. Hasil penelitian menunjukkan lahan kritis di kawasan dalam dan luar hutan lindung di Kecamatan Kertasari diklasifikasikan dengan empat kelas. Kelas dominan yang terdapat pada kawasan hutan lindung adalah kelas agak kritis dengan luas mencapai 1380,07 Ha, dan kelas terkecil adalah kelas tidak kritis dengan luas mencapai 107,59 Ha. Sedangkan lahan kritis diluar kawasan hutan lindung dengan kelas yang dominan adalah kelas potensial kritis dengan luas mencapai 1732,39 Ha, dan kelas terkecil adalah kelas tidak kritis dengan luas mencapai 268,91 Ha. Pada kawasan hutan lindung desa dengan luas lahan kritis terluas adalah Desa Neglawangi dengan luas mencapai 396,24 Ha, untuk luas terkecil adalah Desa Resmitingal dengan luas mencapai 0,09 Ha. Kawasan diluar hutan lindung dengan luas lahan kritis terluas adalah Desa Neglawangi dengan luas mencapai 858,97 Ha, dan luas terkecil adalah Desa Sukapura dengan luas mencapai 0,005 Ha. Hasil tersebut kemudian dianalisis untuk rekomendasi rehabilitasi lahan kritis menggunakan agroforestri.

Abstract

The need for built-up area increases along with a rise in population growth in many regions. This phenomenon leads to a tremendous change in agricultural land and decrease in the environmental carrying capacity. Therefore, this study aims to determine Land Use and Land Cover (LULC) dynamics and the drivers used for its modeling in 2030. This is a quantitative study, which uses the dynamic models of Geographic Information System (GIS) and Markov-CA. Data were obtained from the CNES-Airbus satellite imageries in 2009, 2014, and 2019 by using Google Earth at East Cirebon. The drivers include road density, distance to CBD, total population, distance to settlements, land slope and distance to rivers. The interaction between drivers and LULC change was analyzed using binary logistic regression. The results showed that the rise of built-up area reached 36.4 percent and causes the loss of 0.78 km2 of agricultural land from 2009 to 2019. The LULC simulation in 2030 shows an increase in the built-up area by 82.85 percent with probabilities above 0.6. Meanwhile the significant drivers for changes include road density and distance to settlements. In conclusion, efforts to reduce LULC change in agricultural land into built-up area is by re-strengthening spatial planning-based environmental awareness for the community.

Abstract

The presence of Cirebon coal-fired power plant I and II caused negative effects to coastal morphology and the quality of marine waters. This also have negative impacts to the fisherman around that sea. This study aims to examine the impact of the Cirebon coal-fired power plant on the water quality of Mundu Bay, Cirebon Regency. Water quality is determined based on total suspended solids (TSS), sea surface temperatures (SST), chlorophyll-A, and salinity in the range 1999 – 2019. Data collection was carried out using satellite imagery of Landsat-5 TM, Landsat- 7 ETM+, and Landsat-8 OLI verified with in-situ field measurements, Sentinel-2 A MSI, and MODIS Aqua imageries. Changes in water quality due to the infrastructure of the two power plants are known through the Mann-Whitney U-Test and Spearman’s correlation analysis. This research shows that two Cirebon coal-fired power plant has a significant effect on changes in the quality of Mundu Bay waters. Changes in water quality are shown by a significant increase in TSS concentrations and SST values ​​accompanied by a decrease in chlorophyll-A levels and salinity levels. Changes in the quality of these waters also disrupt marine biota habitat and cause fishermen in around are difficult to get the ideal catchment yield.

Abstract

ABSTRACT Osteoporosis is a "silent disease" that can weaken bones and cause fractures. Two from five of Indonesia's population at risk of osteoporosis and it is estimated in 2025 that number will become tripled. It has been found a kind of drug, that serves as cathepsin K inhibitors, that shows great potential in reducing osteoporosis. Cathepsin K has an important role in tissue destruction, bone remodeling, and cartilage destruction, This study is aimed to verify the effect of the cathepsin K vaccine candidate to the decrease of bone resorption in Rattusnorvegicus strain wistar post-ovariectomy. Female Rattusnorvegicas Strain Wistar (age: 10-12 weeks) are divided into 5 groups: control (-), control (+) with ovariectomy, the treatment groups are ovariectomized and given cathepsin K 50 ng/200 µL, 100 ng/200 µL, and 200 ng/200 µL.. Surgery perform on the 30th day and then IgG titers of anti-cathepsin K and ALP serum level are measured and the number of osteocytes is counted. ANOVA test shows that the administration of the vaccine candidate, cathepsin K that are added with CFA-IFA, is significantly increase the titers of IgG anti-cathepsin K in the serum (p = 0.00). The administration of cathepsin K 50 ng/200 µL, 100 ng /200 µL, and 200 ng/200 µL do not significantly reduce the number of osteocytes. The administration of cathepsin K 50 ng/200 µL, 100 rig / 200 µL, and 200 ng/200 µL do not increase the ALP serum levels (p> 0.05) significantly. The conclusion of the study is that the administration of the cathepsin K vaccine candidate can increase the IgG anti-cathepsin K titers in Female Rattusnorvegicus Strain Wistar Rats Post-ovariectomy, but do not significantly affect the number of osteocytes and ALP serum levels. Therefore, the osteoporosis vaccine candidate with cathepsin K as a basic material still need to be researched and develop
