Judul: Analisis daerah bahaya dan resiko banjir berdasarkan karakteristik geomorfologi dan aplikasinya untuk evaluasi tata ruang Kota Sintang
Abstrak: The Sintang City, located in West Borneo, is annually inundated by flood during rainy season. The city itself is growing in the Y-junction of two big river i.e. Kapuas and Melawi, or geomorphologically it is growing in the major floodplain of those rivers. In 1963, flood disaster has occurred during several days, inundating most of settlements and there were many of victims and damages. Although in the last recent years the floods are moderate, but such big event could be repeated in the future time. Study of flood and mitigation will be important for the study area for reducing disaster. The aims of this research are to (1) analyses and mapping of flood hazard and risk zones and (2) to analysis and evaluate the Sintang’s land use planned (RDTRK) based on flood hazard. Geomorphological approach is used for analyzing flood hazard based on morphogenesis and morphology parameters, and history of floods. The flood hazard map will be used together with actual land use map for analyzing flood risk. Scoring of geomorphological and land use parameters is applied and GIS spatial analyses (overlay) is used for assessing hazard, risk, and evaluation of RDTRK. The results indicating that 0,8% area of Sintang classified as very low of hazard, 57,2% low, 31,5% moderate, and 10,5% high. It represent that most of area of the city is really hazardous areas of flooding, it match to its morphogenetic landforms of study area dominated by fluvial landforms. According to risk analysis result, there are 0,9% of city’s area has very low risk of flooding, 70,1% low, 22,5% moderate, and 6,5% high. These two later classes wholly cover developed areas, such as residential, office, and commercial areas, signifying that all developed areas in the city will be threated moderately to highly by flood hazard. The risk analysis of RDTRK is divided in two, namely the RDTRK’s actual risk and the RDTRK’s potential risks successively represented the planned area that has been realized and those for not realized yet. The result shows that 352 Ha developed areas, 1.435 Ha vegetated areas, and 10 Ha developing agricultural area classified as moderate to high actual risk, while 1.467 Ha developed areas, 178 Ha vegetated areas, and 745 Ha developing agricultural area classified as moderate to high potential risk. These figures demonstrated that the greatest extend of potential risk possed by developed areas planned. Hence RDTRK should be re-evaluated together with mitigation planned in order to minimize the extend of risk. Flood mitigation program will be an urgently program, such as building of rivers dykes or drainage canals of study area, and reboisation of upland areas of Kapuas and Melawi watersheds.

Judul: Model Spasial Genangan Dan Risiko Bencana Banjir: Studi Kasus Wilayah Sungai Mangottong, Kabupaten Sinjai
Abstrak: Flood is one of the natural disasters that often happens in Indonesia due to high rainfall. Sinjai is one of the regencies in South Sulawesi which had been severely hit by flood. It happened in 2006 which caused many losses and victims, especially in the capital regency due to the overflow of Mangottong River. The objectives of the research were to develop and simulate spatial modeling of flood inundation, analyzing hazard, vulnerability, and risk level of flood in Mangottong River area. Spatial modelling of flood inundation is using GIS based DEM and flood volume data, while the risk was analyzed by combining of hazard and vulnerability components. Inundation model validation results showed a fairly good accuracy for the flood depth in 2006 simulation with the value of R2 was 0.72. Flood hazard level based on water depth of 25 year return period simulation model result showed that most area of North Sinjai District are in low and middle class, while East Sinjai District are in high class of hazards. Flood vulnerability and flood risk level showed North Sinjai District has a higher percentage of area than East Sinjai District for all classes.

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
