Judul: Identifikasi Sebaran Spasial Resiko Tanah Longsor Sebagai Upaya Mitigasi Bencana di Sub DAS Cisadane Hulu
Abstrak: Application of Geographic Information Systems (GIS) and remote sensing can be developed for the management in an attempt to handle of natural disasters such as landslides in the area within a watershed. The purpose of this study was to obtain a distribution map of hazard level of landslides and its risk as a result of landslides at upper Cisadane Sub watershed, using GIS technologies. The results of the analysis showed that areas with high susceptible, medium, low of landslide covered approximately 8539.83 Ha (21.89%), 26243.56 Ha (67.27%) and 4226.84 Ha (10.83%), respectively. Meanwhile, the risk of landslides analysis depicted that in general the upper Cisadane Sub watershed were mostly included as low risk of landslides disaster. It was very unfortunate, that some areas designated as residential zone within spatial plan were situated on areas with a high susceptible of landslides disasters. This was not accordance with the principle of spatial planning.

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: 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
