Judul: Studi Geomorfologi dan Analisis Bahaya Longsor di Kabupaten Agam, Sumatera Barat
Abstrak: Sumatra is an active tectonic-volcanic island located in the collision of Indo-Australian and Eurasian plates. The movement of the plates often caused natural disasters and one of which led to landslide. Landslides are one of geomorphic processes which often times generating a disaster in Sumatra. Agam Regency is one of the administrative areas in Sumatra where the landslides have frequently been taken place. This research aims to (1) learned geomorphological condition of Agam Regency and (2) to assess landslides susceptibility and hazard. The methods of assessment used were Multi-Criteria Evaluation (MCE) and the parameters comprise slopes, lithology, precipitation, soil, and land cover/land use. Those parameters were analyzed by geographical information system (GIS) technique using score and weighting. Ground checked has been hold for validating tentative result of analysis and collecting primary data. The result showed that the geomorphology of Agam Regency characterized by the plain area in western part and hilly/mountainous area in the middle and eastern parts (the so called Bukit Barisan Mountain). Based on landslides susceptibility analysis, it indicates that 54.3 % of Agam Regency classified as safe area (1211.5 km²) and conversely 18.6 % as severely susceptible area (414.7 km²). According to landslides hazard analysis, it shows that 51.3 % of Agam Regency classified as safe area (1146.7 km²) and contrarily 13.6 % as severely hazard area (303,6km²). Geomorphologically, all severe class of landslides susceptibility and hazard areas situated in the hilly/mountainous areas possessing slopes steepness of 15 % to > 40 %.

Judul: Mapping and Analysing of Landslide Hazard Zone and its Mitigation Using Geographic Information System (Case Study in North Sumedang and South Sumedang Subdistric, Sumedang Distric, West Java)
Abstrak: Landslide is the natural disaster that most frequently occurred in the study area of North Sumedang and South Sumedang subdistric. The existing of landslide hazard and risk map s are not yet adequate to be use in policy making. The aim of the research is to provide potential hazard and risk maps to mitigate landslide hazard using geographic information system technology. The result showed that most area in the North Sumedang and South Sumedang subdistrict is moderate landslide hazard covered 8.460 Ha (65,51%), high landslide hazard covered 2.798 Ha (21,67%), low landslide hazard covered 1.570 Ha (12,16%) and very low landslide hazard covered 85 Ha (0,66%). Combining landslide hazard with property value has produced map of landslide risk. Neverthe less most areas are low risk class (7.962 Ha/61,67%) and the high risk areas are only occurred in small places (568 Ha/4,4%). This phenomena showed that area with high potential class of landslide hazard is not always having a high value of risk. The risk is determined by properties value such as: infrastructure, road network and land use, while the landslide hazardous class is determined by natural factors such as: slope, soil type, geology and land use.

Judul: Performa produksi burung puyuh (Coturnix-coturnix japonica) yang diberi pakan dengan suplementasi omega-3
Abstrak: Supplementation of Omega-3 in ration may enhance Omega-3 and lower the cholesterol contents in quail eggs. However, its impact to productive performances has not been clearly proved. This current experiment aimed to study the influence of Omega-3 supplementation in ration on productive performances of Japanese quail (Coturnix-coturnix japonica). This study was carried out for two months in the field laboratory of Poultry Production and Technology, Faculty of Animal Science, Bogor Agricultural University. This study involved 298 Japanese quail age 10 weeks and designed completely randomized in 5 treatments with 4 replications. The applied treatments were Omega-3 supplementation in the ration: P1 (control), P2 (1.5% Omega-3), P3 (3% Omega-3), P4 (4.5% Omega-3), and P5 (6% Omega-3). The observed traits were feed consumption, egg production, egg weight, feed conversion, mortality, and index of quail egg. All data were collected and descriptively analyzed. This study revealed no influence of Omega-3 supplementation to the production performance and index of quail egg.
