Judul: The Application of GIS and Remote Sensing for Determining Sensitive Area Based On Geological Hazard Perspectives
Abstrak: Geological hazards is hazard which is usually classified as geological: earthquakes, faulting, tsunamis, volcanoes, avalanches, landslides, and floods. It is a well known fact that geological hazard disaster strikes countries, causes enormous destruction and creates human sufferings and produces negative impacts on national economies. Due to diverse geo-climatic conditions prevalent in different parts of the globe, different types of geological hazard disaster strikes according to vulnerability of the area. Worldwide growth of population and particularly concentration of man and his works into urban areas, has heightened such treats to level where large-scale, and often costly, planning to reduce the hazard has become essential in many country. By using GIS and Remote sensing technology to determine sensitive area based on geological hazard persepectives, constitute the new point of view in performing hte research. Remote sensing can enable geomorphic study of areas that are inacessible to field-investigation and GIS can performing spatial analysis by an unique way. Such conducting unsupervised to determine settlement area, generating slope from satellite imagery and with GIS all result can be map and analysis by using spatial analysis. To develop knowledge base which will use as an input for decision support system. The core and simultaneously benefit of this research is the capabilities of GIS and Remote Sensing technology that can help geoscientist especially geologist to capture, manipulate and analyze of information about an object without physical contact as preliminary survey (reconnaissance), mainly for geomorphic study of areas that are inaccesible to field-base investigation. Moreover, by utilizing the available sources of data (data provider) GIS and Remote Sensing can be used more effective and efficient compared to the current or traditional methods for interpreting extremely large cover research area. The sensitive area in research area, occupied by volcanic and sedimentary breccias, conglomerate, sandstone, limestone, claystone and alluvium, with slope controlled bigger than 15%. In some places, its also occupied by igneous rock with slope controlled bigger dan 50%, particularly the area with dominantly contrlolled by geologic structure. Determination concerning unstable zone in term of ‘sensitive area’ in research area immensely supported by principal component analysis in determining iron-oxide and clay-hydroxyl (alteration zone) combined with geomorphological interpretation (geology structure & drainage pattern), slope and rock characteristics weighting. There are 215 villages in Banten and West Java province which occupied sensitive area, thus detail field-investigation can be focused concerning those areas.

Judul: Pemetaan kawasan berpotensi banjir menggunakan sistem informasi georafis
Abstrak: Remote Sensing and Geographic Information System (GIS) can be applied to identify potential flood area. Remote Sensing helps to extract information without direct interaction with the object. On the other hand, GIS can be used to identify flood prone of an area using overlay method toward the parameters that causes flood phenomena. The object of this research was to mapping the vulnerability of flood area in Indramayu Regency using cartography models of biophysics parameters, to study the distribution and characteristic of flood area in Indramayu Regency, and to study the result using different rainfall parameters and weight category for mapping vulnerable flood area in Indramayu Regency. Data processing was done using software such as ArcView 3.3, ERDAS Imagine 9.1, and Frame & Fill (USGS). The used data are rainfall, Landsat Imagery; DEM, SRTM data; soil map, river map, and landform map. The methods consist of imagery analysis, DEM data analysis, rainfall data analysis, attribute data analysis, spatial analysis dan vulnerabilty class analysis. Rainfall parameter divided into two groups, the first group used annual mean rainfall data and the second group used monthly mean rainfall data (threemonth peak of rainy season). Proportion of parameters that called as a weight category in this research divided into two groups, the first group with different weight and the second group with equal weight. The results showed that Indramayu Regency can be concluded as a potential flood area, where the north side of Indramayu Regency is more vulnerable rather than the south side. The land characteristic of the potential flood area are flat area, alluvial plains, bad drainage, and paddy field land cover. The map that using monthly mean rainfall data and different weight is more representative for mapping flood area in Indramayu Regency.

Judul: Quail Blood Cholesterol Levels (Coturnix coturnix Japonica) On Starters, Growers and Layers phase
Abstrak: Cholesterol is one of fat formation components which is also the main sterol in animal tissues. Therefore its presence are contributing to development and growth of the body. This study aimed to determine blood cholesterol levels and body weight of quail in the starter,grower and layer phases, which were taken at the age of 18 days, 25 days and 330 days. The quail (Coturnix coturnix Japonica) used were ten tails of the starter phase, grower phase and layer phase. Blood cholesterol levels were measured using a NESCO MultiCheck 3 in 1 tool and body weight was calculated using a digital scale. Cholesterol levels decreased from the starter (158,40 mg/dL) phase to the grower phase (123,00 mg/dL) and increased again in the layer phase (219,6 mg/dL). The highest blood cholesterol value was obtained in the layer phase. The body weight over time continued to experience an increase and the increase in body weight from the starter to the layer phase was not followed by an increase in cholesterol levels. Cholesterol levels are used according to their physiological needs, Kolesterol merupakan salah satu komponen pembentuk lemak yang juga merupakan sterol utama dalam jaringan hewan, oleh karena itu kehadirannya memberikan kontribusi untuk perkembangan dan pertumbuhan tubuh. Penelitian ini bertujuan untuk mengetahui kadar kolesterol darah dan bobot badan burung puyuh pada fase starter, grower dan layer, yang diambil pada umur 18 hari, 25 hari dan 330 hari. Burung puyuh (Coturnix coturnix Japonica) yang digunakan sebanyak sepuluh ekor pada masing-masing fase starter, fase grower dan fase layer. Kadar kolesterol darah diukur menggunakan alat NESCO MultiCheck 3 in 1 dan berat badan dihitung menggunakan timbangan digital. Kadar kolesterol menurun dari fase starter (158,40 mg/dL) ke fase grower(123,00 mg/dL) dan meningkat lagi pada fase layer(219,6 mg/dL). Nilai kolesterol darah tertinggi diperoleh pada fase layer. Bobot badan dari waktu ke waktu terus mengalami peningkatan yang dan peningkatan bobot badan dari fase starter ke fase layer tidak diikuti dengan peningkatan kadar kolesterol yang artinya bobot badan tidak berpengaruh pada kadar kolesterol burung puyuh. Kadar kolesterol digunakan sesuai dengan kebutuhan fisiologisnya
