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: Evaluasi Risiko Banjir dan Pola Ruang di Daerah Aliran Sungai Cisadane.
Abstrak: Flood disaster in Cisadane river have resulted substantial consequences in Jakarta and Banten (Tangerang) regions anually. To cope with the problem, flood assessment in the watershed should be conducted to establish disaster mitigation strategy constructed in spatial planning. This research aims (1) to refine land cover and landform map in the watershed; (2) to estimate Cisadane peak discharge; (3) to analyze flood hazard and the associated risk; and (4) to evaluate current spatial planning based on established land cover, flood hazard, and flood risk. Geographic information systems (GIS) coupled with multiple criteria evaluation (MCE) is demonstrated to assess flood hazard considering several parameters, including landforms and recorded flood events. In this research, flood risk is modeled as a function of flood hazard and its vulnerability and comprises of several variables such as social, economic, demographic, and physical properties. It was found that spatial distribution of flood hazard is influenced by flat landform and shaped by fluvial processes and fluvio-marine landforms. Flood is affected by upstream precipitation and downstream water fluctuation (tidal). Flood hazard and risk is classified into low, moderate, and high level. This research found that areas having low, moderate and high-level flood hazard are about 37.124 ha, 15.564 ha, and 1.587 ha respectively. Majority of research area are low risk (41.415 ha), while about 10.972 ha areas are categorized in moderate level. Only about 1.891 ha regions are at high-level risk. Largest flood is contributed by downstream Cisadane region, which has the highest peak discharge (1.833 m3 sec-1). Analysis of spatial planning indicates that flood mitigation is urgent, especially through drainage and dyke development.

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.
