Judul: Landscape Planning for the Preservation of Cisadane Sub-Watershed in Situgede Area with Bioregion-based
Abstrak: Situ mempunyai peran penting dalam pengendalian tata air dengan menahan hidrograf aliran masuk dan mengurangi debit aliran air keluar. Sub DAS Cisadane Kawasan Situgede yang mencakup tiga Daerah Tangkapan Air berupa situ (Situ Gede, Situ Panjang, dan Situ Burung) dapat menjadi ancaman bagi keberlangsungan sistem tata air. Usaha pelestarian air Sub DAS Cisadane Kawasan Situgede diperlukan sebagai upaya memelihara keberadaan serta keberlanjutan neraca dan fungsi sumber daya air agar selalu tersedia dalam kuantitas dan kualitas yang cukup untuk kebutuhan manusia, baik sekarang maupun di masa yang akan datang. Penelitian ini bertujuan menyusun rencana lanskap Sub DAS Cisadane Kawasan Situgede sebagai kawasan pelestarian air berbasis bioregion. Perencanaan dilakukan dengan pendekatan analisis terhadap unit bioregion, unit lanskap, dan unit tempat berdasarkan modifikasi konsep DAS kecil. Berdasarkan zonasi modifikasi konsep DAS kecil, dihasilkan perencanaan lanskap dengan luaran berupa rencana lanskap dan rencana turunan berupa rencana hardscape, rencana tata hijau, dan rencana utilitas.

Judul: Alokasi penggunaan lahan berbasis konservasi sumber daya air di sub DAS Cisadane Hulu
Abstrak: Problems of land use in Cisadane Hulu sub watershed has led to a decrease in water resources, so that water resources conservation needs more attention. One of the efforts to conserve water resources is allocating landuse properly. For that reason a research was conducted at Cisadane Hulu sub watershed. The objectives of the research were (1) to identify the sub-sub watersheds performance, (2) to evaluate various alternative of the land use allocations, (3) to identify people preference about optimal land use, and (4) to formulate strategic direction of land use allocation. The methods of data processing analysis included spatial analysis, prediction of water discharge, and sedimentation that integrated in the AVGWLF model, and Analytic Hierarchy Process. The parameters used include Land Cover Index (IPL), the runoff coefficient (C), Erosion Hazard Index (IBE) and suspended sediment concentration (SC). Results of the analysis showed that in general Cisadane Hulu sub watershed has “Poor” performance. Among sub-sub watershed, 36 sub-sub watersheds had “Poor” performance and 8 sub-sub watersheds had “Medium” performance. To improve the performance, 3 scenarios were simulated, i.e. land use allocation based on Zone Function, based on Land Capability and based on RTRW. The Zone Function scenario produced the best result, followed by Land Capability and RTRW scenario’s. In the best scenario, Cisadane Hulu sub watershed was devided into 3 main areas with different of land use priority. Protected area is directed for forest, buffer area is directed for forest or mixed plantation and cultivated area is directed for rice field. AHP analysis show that people prefer to use buffer area for mix plantation and cultivation area for rice field. To implement the best allocation, policy strategies is necessary because of the mismatch between both of those results with the determination of the legally status of the area function, socialization, community empowerment and institutional strengthening.

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.
