Judul: GIS Approach To Determine The Earthquake Hazard Areas in Feasibility Site for Nuclear Power Plant in Bangka Island
Abstrak: Bangka Island is an area that had been assessed to be a feasibility site for nuclear power plant in Indonesia. Although the area is located far from the ring of fire’s the impact of an earthquake is still felt, however needed to be examined. There were not many earthquake epicenters that occurred in this island. The purpose of this study is to determine earthquake hazard areas using Geographical Information System model. The methodology used to determine earthquake hazard areas is based on Simple Additive Weighting (SAW) analysis model which requires different input variables that were implied. The model inputs include slope, earthquake intensity, predominant period, amplification factors, lithology and fault distance. The weight and rank values are assigned to the layers and to the classes of each layer respectively. Based on the final earthquake hazard areas map, hazardous areas in Bangka Island are located in north and south parts of the study area. The areas belong to the feasibility site for nuclear power plant is categorized moderate earthquake damage areas. The results cannot be expected to be completely accurate but can provide a good representation of the process. Validation of results will inevitably be difficult and should be measured in the field. The information resulting from this study could be useful for raising awareness about hazard and possible mitigation measure, a key component of disaster risk reduction planning.

Judul: Tsunami risk assessment using probabilistic approach and GIS-based SAW Method: case study coastal area of Padang Sumatera Barat, Indonesia
Abstrak: Tsunamis are among the world's most destructive natural hazards. Tsunami is a system of gravity waves formed in the sea as a result of a large-scale disturbance of sea level over a short duration of time. A tsunamigenic earthquake is an earthquake that has generated a tsunami. In Indonesia, during the period 1600-2000, tsunamigenic earthquake occurrences are very often (90.5%). The objective of this research is to assess tsunami risk using Probabilistic approach and GIS-based SAW method, on coastal area of Padang, Sumatera Barat province, Indonesia as a case study. The Probabilistic approach was chosen to assess the probability of distributions and recurrence times (return periods) for tsunamigenic earthquakes with different magnitudes, for Indonesian region in Eurasia plate. The GIS-based SAW method is required to assess tsunami risk as spatial information, using the integration of the hazard and vulnerability. The outputs of this research are the probability of future tsunami for Indonesian region in Eurasia plate, tsunami risk zone and regional planning recommendation for coastal area of Padang.

Judul: Toksisitas Mimosin terhdap Larva Corcyra Cephalonica Stainton (Pyralidae, Lepidoptera)
Abstrak: Penelitiaa ini bertujuan untuk meapelajari toksisitas dan pengaruh pemberian mimosin terhadap perirembangan larva C. ceohalonica Stainton. Pemberian mimosin pada taraf konsentrasi 0.1 persea dan 0.2 persen tidak berbeda pengaruhnya terhadap mor.talitas larva C. ceohalonica. Tetapi sangat berbada nyata bila dibandingkan dengan kontrol. Cara aplikasi tidak menunjukkan perbedaan, demikian pula tidak terdapat interaksi antara cara aplikasi dengan taraf konsentrasi yang digunakan. Cara aplikasi pengaeukan dan perendaman tidak berbeda nyata b i l a dibandingkan dengan cara penetesan dalam pengaruhnya terhadap j u d a h imago C. ce~halonicay ang keluar. Sedangkan penambahan konsentrasi mimosin 0.1 persen dan 0.2 persen tidak berbeda pengaruhnya terhadap jumlah imago yang keluar.
