Judul: Spatial palnning model for coastal area. case study: Kabupaten Bekasi North Coastal Area.
Abstrak: The propose of the study is to purposes as spatial planning model for coastal areas, integrating land and marine aspect. The comp lexity of issues in coastal areas such as heterogentiy of life, potentials of economi c resources, and tobe explored and developed. Coastal areas as the basic matrix for development i s dynamic, difficult for clear and exact delineation, and do not have clear manage ment boundaries. The approach employed to formulate the spatial plan ning model for coastal areas is a descriptive method both quantitative and quali tative. The dynamics taking place in coastal areas require different planning approach from a land based spatial planning, and the main indicators are its carrying capacity, land suitability and economic value of each land utilitation. These indicators also be app lied in the coastal zone spatial planning model purposed in this study, with the n ecessary modification as appropriate in coastal zone.

Abstrak: Batang regency is one of the coastal districts on the north coast of Java, which has a 38.75 km long coastline and vast ocean of approximately 287 060 km2. Batang coastal area is a region of highly productive and have high economic value, but on the other hand are also vulnerable to damage. The coastal area strategic plan document Batang in 2011, identify that there are variety of problems occured in coastal areas Batang include abrasion, accretion, sedimentation, flood, narrowing river bodies, destruction of mangroves, pollution of water and soil, ego sectoral, institutional and community participation in coastal management. Therefore the management of coastal areas should be planned and integrated and provide maximum benefits to all stakeholders, especially in coastal communities. Spatial planning is one tool in the management of coastal areas, where the main objective of spatial planning is to improve the society welfare, the growth and the ecosystem conservation. According to Act No. 26 of 2007 on Spatial Planning, spatial utilization at district must consider supportive and carrying capacity of environment. This study aims to assess and evaluate the environment carrying capacity and the spatial utilizations in Batang coastal areas; assess community understanding against management and spatial planning; analyze the level and form of community participation in the management of coastal areas and formulate strategic referrals to the management coastal areas in Batang. The methods used in this study are analysis based on Geographic Information Systems (GIS) as well as the descriptive analysis. Environment carrying capacity analysis to the land area was based on land capability. Determination of land capability class was done by using Boolean technique (Regulation of the Minister of Environment Number 17, 2009). Evaluation of carrying capacity and spatial utilization was done by overlaying the maps. Batang waters conditions assessed from the data physical and chemical parameters were adjusted to the Minister of Environment Decree No. 51 of 2004 on Sea Water Quality Standard. To find the understanding and participation of the community were analyzed descriptively, based on the results of the questionnaire. From the results of the analyzes, then performed such synthesis to formulate strategic direction of coastal areas management. The results showed that environment carrying capacity in the coastal areas of Batang based on land capability is still appropriate (98.29%). The conditions of coastal water of Batang are still appropriate for marine life, but in a few locations (Batang, Tulis and Gringsing sub-districts) orthophosphate levels have already exceeded the quality standard. Currently, more than 70% of the land use in coastal areas are still appropriate/consistent with the spatial planning. In general, the level of public understanding of policies related to the management and spatial planning of coastal areas in Batang is still low, mean while associated with the land vii utilization in coastal areas, the level of public understanding belongs to moderate level. Based on Arnstein ladder typology, the level of community participation in general categories as Information category. Participation form exhibited that the majority of respondents participate at utilization, conservation and monitoring activity. Activities follow the coaching/training is a form of activity which is

Judul: Peran Antibodi Kuning Telur (IgY) Sebagai Anti Adhesi dan Opsonin Untuk Pencegahan Serangan Mutan Streptococcus Serotipe d (Streptococcus Sobrinus)
Abstrak: Ayam petelur memiliki peran penting sebagai penghasil antibodi poliklonal. Antibodi ayam atau dikenal dengan imunoglobulin Y (IgY) dapat dipurifikasi dari kuning telur. Biaya untuk memproduksi IgY relatif lebih murah daripada antibodi mamalia karena biaya pemeliharaan ayam tidak mahal, relatif lebih mudah dan cepat menghasilkan telur. Penelitian ini bertujuan untuk mempelajari peran IgY spesifik MS serotipe d (Streptococcus sobrinus) (IgY-Ss) sebagai anti adhesi dan opsonin pada sel epitel pipi. IgY spesifik dikoleksi dari telur ayam Single Comb Brown Leghorn yang telah diimunisasi dengan antigen utuh S. sobrinus. Imunisasi diaplikasikan secara intravena dengan dosis antigen utuh S. sobrinus 0,5 ml (109CFU) selama tiga hari berturut-turut pada minggu pertama . Kemudian dilakukan pengulangan imunisasi (booster) sebanyak tiga kali dengan interval waktu seminggu secara intramuskular dengan dosis antigen utuh S. sobrinus 1 ml (109CFU) dalam Freud’s adjuvant complete pada minggu kedua dan dalam Freud’s adjuvant incomplete pada minggu ketiga dan keempat. Uji agar gel presipitasi (AGP) dilakukan untuk mengetahui terbentuknya IgY spesifik S.sobrinus (IgY-Ss). Ayam yang serum dan telurnya positif pada uji AGP kemudian telurnya di koleksi untuk dilakukan ekstraksi. Ekstraksi IgY-Ss dari kuning telur menggunakan metode PEG-amonium sulfat kemudian dipurifikasi dengan fast protein liquid chromatography. Konsentrasi IgY-Ss yang telah dimurnikan dihitung dengan spektrofotometer UV. Kemudian berat molekul IgYSs ditentukan dengan metode SDS Page dan menggunakan pewarnaan Commasie blue. Aktifitas biologis IgY-Ss sebagai anti adhesi dipelajari dengan assay adhesi secara in vitro menggunakan sel epitel pipi manusia. Assay adhesi dilakukan dengan dosis IgY-Ss 100 μg . Peran IgY-Ss sebagai opsonin dipelajari dengan assay fagositosis menggunakan dosis IgY sebesar 100 μg. Hasil penelitian yang diperoleh adalah IgY-Ss telah terbentuk dalam serum pada minggu kelima, sedangkan dalam telur pada minggu kesembilan setelah imunisasi pertama. Pre-inkubasi 100 μg IgY-Ss pada sel bakteri dan epitel pipi mampu menurunkan nilai adhesi dari 39,9 sel bakteri/ sel epitel pipi menjadi 30,7 sel bakteri/ sel epitel pipi. Opsonisasi dengan 100 μg IgY-Ss tidak meningkatkan aktifitas fagositosis namun hanya meningkatkan kapasitas fagositosis makrofag dari 1,6 sel bakteri/ makrofag menjadi 5,17 sel bakteri/ makrofag. Kesimpulan dari penelitian ini adalah ayam mampu memproduksi IgY spesifik anti S. sobrinus (IgY-Ss) pada serum dan kuning telur. Proses opsonisasi IgY-Ss pada S. sobrinus dapat meningkatkan kapasitas fagositosis. Preinkubasi IgY-Ss pada S. sobrinus (107 CFU/ ml) dan sel epitel pipi (105 sel) dapat mengurangi adhesi bakteri tersebut pada sel.
