Judul: Landslide analysis in the Cisarua District Using Geographic Information System
Abstrak: Badan Nasional Penanggulangan Bencana (BNPB) menyebutkan bahwa telah terjadi bencana longsor di sepanjang bulan Desember 2014 terdapat 9 titik longsor dan pada 5 Februari 2018 kembali terjadi longsor yang terdapat di 22 titik yaitu di Desa Batulayang, Tugu Utara, Jogjoan dan Tugu Selatan. Secara topografi kontur tanah berada pada kemiringan yang curam, dengan intensitas curah hujan mencapai 575.1 mm/bulan sehingga dapat berpotensi longsor. Tujuan penelitian untuk mengidentifikasi kerawanan dan keakuratan titik lokasi longsor berdasarkan dua metode yang dikeluarkan oleh Direktorat Vulkanologi dan Mitigasi Bencana yaitu DVMBG 2004 dan DVMBG 2005. Penelitian ini menggunakan data penginderaan jauh dengan melakukan pembobotan terhadap parameter longsor. Kemudian memvalidasi data dengan titik kejadian longsor. Hasil analisis dengan DVMBG 2004 menunjukkan tahun 2014 dan 2018 klasifikasi rawan longsor mendominasi dengan persentase 82.54% dan 64.59%. Hasil analisis menggunakan DVMBG 2005 tahun 2014 dan 2018 klasifikasi rawan mendominasi potensi longsor dengan persentase 68.63% dan 84.61%. Pada model pendugaan longsor DVMBG 2004 terdapat 9 titik yang tidak tervalidasi. Sedangkan pada DVMBG 2005 seluruh titik kejadian tervalidasi sehingga model pendugaan longsor DVMBG 2005 sebagai metode yang di rekomendasi untuk pembuatan peta potensi kerawanan longsor. Kata kunci: DVMBG, keakuratan, longsor, titik lokasi, National Disaster Management Agency stated that there have been landslides throughout December 2014 there were 9 landslide points and on February 5 2018 another landslide occurred in 22 points, namely in Batulayang Village, North Tugu, Jogjoan and South Tugu. Topographically, the land contour is on a steep slope, with rainfall intensity reaching 575.1 mm/month. The purpose of this study is to identify the vulnerability and accuracy of landslide location points based on two methods issued by the Directorate of Volcanology and Disaster Mitigation, namely DVMBG 2004 and DVMBG 2005. This study uses remote sensing data by weighting landslide parameters. Then validate the data with the point of landslide occurrence. The results of the analysis with the 2004 DVMBG show that in 2014 and 2018 the landslide-prone classification dominated with a percentage of 82.54% and 64.59%, respectively. The results of the analysis using the 2005 DVMBG in 2014 and 2018 classification of hazard dominates the potential for landslides with a percentage of 68.63% and 84.61%, respectively. In the 2004 DVMBG landslide estimation model, there are 9 points that are not validated. Meanwhile, in the 2005 DVMBG all points of occurrence were validated. So the 2005 DVMBG landslide estimation model is the recommended method for making landslide hazard potential maps. Keywords: Accuracy, DVMBG, landslide, point location

Judul: Pemetaan Kawasan Rawan Bencana dan Analisis Resiko Bencana Tanah Longsor dengan Sistem Informasi Geografis (SIG) (Studi Kasus Kawasan Kaki Gunung Ciremai, Kabupaten Majalengka)
Abstrak: Landslide disaster is one of the natural disasters that often occur in Indonesia and is generally common in mountainous regions, the rainy season and is closely related to natural conditions such as soil type, rock type, rainfall, land slope and land cover. The aim of this study is to mapping hazard landslide areas and to analyze the risk of landslides in the Ciremai foothills region Majalengka district. Puslittanak (2004) is using to be a model of analyzing landslide susceptibility prediction in study area, the formula is Total Score = 0,3 FRain Falls +0,2 FGeology +0,2 FLand Slope +0,2 FLand Cover +0,1 FSoil Types. Risk analysis was analyzed by quantitative models based on research of Alhasanah (2006) through the overlaying property map score (infrastructure map, road map and land cover) with landslide vulnerability map. In study area, low landslide susceptibility class dominated by flat topography, the dominant rock type is Qa (Aluvium), soil type is Latosol and rainfall intensity 2500-3000 mm/year. Medium landslide susceptibility occur in flat to a relatively steep slope with the type soil dominated by Andosol and level of rainfall intensity is 2500-3000 mm/year. At high landslide susceptibility, dominated land cover is forest with steep topography (15-30%), rock type is dominated by Qvu and the soil type is Andosol with rainfall 3000-3500 mm / year. Very high vulnerability to landslides mostly located in forest areas with very steep slope (>45%), high rainfall intensity 3000-3500 mm/year and dominated by Qyu rock type and Andosol soil type. Based on the analysis of vulnerability map, in area study obtained low vulnerability covered area 2160,45 hectares, medium vulnerability with covered 15319,71 hectares, 21992,49 hectares of high landslide vulnerability and very high vulnerability covered 6191, 91 hectares. Very high vulnerability mostly located in Argapura with 2811,78 hectares (45,41%). Based on the analysis of risk maps, the area of research has a low risk area with a wide level of 13212,36 hectares (28,93%), medium risk level covered 31507,38 hectares (69,00%), high risk level covered 806,94 hectares ( 1,77%) and very high risk level covered 137,88 hectares (0,30%). Areal distribution of very high risk level areas are the largest in the Maja with covered area 32,67 hectares (23,69%).

Judul: Kandungan Kolesterol dan Vitamin A Ayam Arab yang Diberi Jamu Ternak Melalui Air Minum
Abstrak: Egg as one source of protein needed by the body contains high amount of essential amino acids, however in reality there is a constraint factor in consuming the eggs which is the high level cholesterol in an egg. Nowadays the cholesterol content of eggs is feared by most of the public in relation to its effect. Excess cholesterol can cause health problems, but on the other hand the yolks contain vitamin A which is good for the body. This research was aimed to study the cholesterol and vitamin A content of Arab chicken egg yolks with addition of herbs through drinking water it is expected to reduce the cholesterol level and increase the amount of vitamin A in egg yolks. This experiment was conducted in poultry house in block C of Animal Science Faculty, Bogor Agricultural Institute, it lasted from June to August 2011. Chicken used in this study was 48 arab hens by age 19 weeks. Research procedures include the preparation of cages and equipment, maintenance and provisions of herbal medicine. The design used in this study was a completely randomized design (CRD). The content of cholesterol during 5 weeks of herbal medicine with level of 5 ml per head and 10 ml per head was 535.28 mg/100 g up to 563.51 mg/ 100 g. The addition of herbal medicine for 3 consecutive days (per week) are mixed in hens drinking. The level differences does not affect the content of cholesterol in egg yolk, but the existence of different herbal medicine addition level provides different amount of vitamin A. The content of vitamin A in egg yolks for a treatment P0 (without herbs) amounted to 596.787 μg/ 100 g, P1 (herbs 5 ml/head/day) : 700.034 μg/ 100 g and P2 (10 ml/head/day) : 800.962 μg/ 100 g.
