Judul: An Alternative Policy in the Management of Kamali Coast as the Result of Reclamation in the Town of Bau-Bau, which Minimizes the Environmental Impact.
Abstrak: The reclamation of Kamali Coast in Bau-Bau was conducted in 2004. This has led to the loss of potential coastal biological resources, especially some of the marine bio-resources, damaged ecosystem of sea grass and coral reefs. It has also caused changes in the landscape (geomorphology) that have an impact on the changes in ocean currents, sedimentation patterns and a shallower estuary of Bau-Bau River. The study was conducted to find appropriate alternative policies, related to the ecosystem management efforts at Kamali Coast resulting from the reclamation in the Town of Bau-Bau, which minimized the environmental impact. It tried to analyze the existing social, economic, and environmental conditions before and after reclamation and used the analytical hierarchy process (AHP). The results showed that the social condition after reclamation is still quite good and well controlled. The economic condition has also contributed significantly to the regional revenue (PAD) of Bau-Bau. However, the environmental condition found some decreased water qualities, especially turbidity, TSS, dissolved oxygen, nitrate and phosphate. This has led to an increased sedimentation, thus a shallower estuary of Bau-Bau River. The alternative first policy obtained from the AHP analysis is a strict regulation for the dumping along the river. A tight regional regulation (Perda) is expected to enforce the companies that dispose waste in the form of sediment to create IPAL in order to minimize the environmental impact in this area.

Judul: Penetapan Lebar Jalur Hijau (Greenbelt) Mangrove Berdasarkan Aspek Ekologi dan Sosial Ekonomi di Desa Sawah Luhur, Kota Serang, Banten.
Abstrak: Coastal high potential in the fields of economy, triggering a massive development. Land-use management indiscretion bad for the environment. For it is necessary for the establishment of mangrove green belt policy wisely according to aspects of ecological and economic soasial to alternative policy-making can be done with an integrated coastal management. This study aims to assess the width of green belt policy and environmental conditions in coastal areas Sawah Luhur Village, and determine the solution of decision making in the green belt policy in Sawah Luhur Village accordance with ecological and socioeconomic aspects. This research was conducted by collecting primary data and secondary. Policy review based on Keppres No. 32 Year 1990 regarding the protected forest areas as well as Regulation Serang. No. 6 Year 2011 regarding Spatial Plan. Biophysical studies carried out through ground check and classify based on agriculture, aquaculture, residential, wooded areas, buffer zones, rivers and highways. Socio-economic studies carried out through interviews with 30 respondents such as: community, government officials, village, district, and city, and students associated with the Sawah Luhur Village. Based on Keppres No. 32 Year 1990 with an average difference in tidal range 0.7 m, the width of the green belt in the coastal Sawah Luhur Village is 91 m. At the study site green belt width 91 m with an area of 45.18 ha, the area is overgrown with mangrove only 50,19% ie 22,68 ha area designated as a Pulau Dua nature reserve. The many weaknesses of the Keppres No. 32 Year 1990, which does not consider socio-economic aspects, causes this policy can not be done well in Sawah Luhur Village. In Perda Serang No. 6 Year 2011 does not explain the establishment of mangrove green belt. Currently people difficulties to meet the needs of clean water due to seawater intrusion reaches 4 km, which affects the scarcity of clean water for the community. In addition to sea water intrusion, drought caused by drought exacerbated the scarcity of clean water. Over time, pollution and environmental damage resulted in the decline in productivity and farm ponds. So the effect on revenue to the village of which the majority of Noble Field work in the field of aquaculture and agriculture. To increase the productivity of land one of them is by way of planting in coastal areas Sawah Luhur Village. According to respondents, especially the coastal land use would be better if used as aquaculture intercropping, because it has advantages in the field of ecology, economy, and tourism. If the pond intercropping can be realized and can be put to good use, then all parties would be better off in many aspects.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
