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.

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: Quality of Eggs Based on Different Age of Chickens from Yong's Farm, Seremban, Malaysia
Abstrak: This study aimed to determine the quality of eggs from different ages of chickens from Yong’s Farm, Seremban, Malaysia. The method used was 60 eggs were collected from three of different ages of chicken; 25 (n=20 eggs), 35 (n=20 eggs) and 58 weeks old (n=20 eggs). The variables included egg weight, shell thickness, yolk color, yolk index, albumen index and Haugh unit. The results showed the highest egg weight was recorded with 58 weeks old chicken. The egg shell thickness found at week 25 week (0,455 ± 0,08 mm), 35 weeks (0,495 ± 0,08 mm) and 58 weeks (0,475 ± 0,08 mm). Yolk color was at the highest mean of.12,6 ± 0,68 (25 weeks) while on week 35 and 58 it ranges between 5,45 ± 0,51 and 5,55 ± 0,51. The yolk index was recorded on week 25 and no specific trends were observed and the yolk index was not significant between 35 and 58 weeks of age. Albumen index was highest at week 25 were (0,129 ± 0,0), week 35 (0,113 ± 0,03) and week 58 (0,088 ± 0,02). The highest HU was recorded at week 25 (94,81 ± 5,33) and decreased to (90,52 ± 6,64) at week 35 and (81,95 ± 6,24) at week 58. It can be concluded that chicken influences both exterior and interior quality, except the yolk color with the quality of eggs decreasing as the age increases.
