Judul: Modeling of co-existence between tourism and fisheries : convergence-divergence analysis in Lembeh Strait North Sulawesi
Abstrak: Perairan pesisir Sulawesi Utara dikenal di dunia internasional karena keanekaragaman hayatinya, seperti Selat Lembeh di Kota Bitung yang juga dimanfaatkan untuk pelabuhan, perikanan tangkap dan pariwisata. Perlindungan sebagian kawasan pesisir untuk konservasi dan pariwisata bahari akan memberikan manfaat baik secara ekonomi maupun ekologi. Namun demikian dalam kondisi dimana area yang dilindungi ini tumpang tindih dengan area penangkapan ikan tradisional maka diharapkan kegiatan-kegiatan ini dapat saling ko-eksis. Penelitian ini bertujuan untuk menjawab issu tersebut melalui pemodelan bio-ekonomi. Secara spesifik tujuan penelitian ini adalah 1) Melakukan analisis komparatif nilai ekonomi antara wisata dan kegiatan perikanan sekaligus melakukan analisis skenario perubahan nilai ekonomi pada suatu kawasan konservasi jika harus ko-eksis dengan kegiatan perikanan; 2) Menganalisis pola konvergensi / divergensi antara wisata dan perikanan di daerah konservasi; 3) Melakukan analisis kebijakan terhadap implikasi ko-eksistensi antara wisata dan perikanan Model ini menunjukkan bahwa Ko-eksistensi antara Pariwisata dan Perikanan akan dimungkinkan ketika manfaat yang diperoleh keduanya menguntungkan. Nilai ekonomi tersebut bagaimanapun belum dapat dimanfaatkan secara utuh karena belum optimalnya pengelolaan sumberdaya alam di Selat Lembeh. Penelitian ini juga menghasilkan empat tipologi interaksi antara konservasi dan perikanan tergantung dari besaran kapasitas ekonomi dan kapasitas biofisik. Beberapa alternative kebijakan untuk melindungi pengelolaan kawasan pesisir yang mungkin dapat dilakukan adalah melalui kemitraan antara pengelola kawasan konservasi dan wisata dengan nelayan (sebagai guide diving,pemandu wisata). Analisis dinamik merupakan interaksi antara kegiatan perikanan yang diwakili dengan potensi perikanan dengan kegiatan pariwisata yang diwakili jumlah wisatawan. Konvergensi terjadi pada tahun ke 40 dengan nilai biomasa ikan sebesar lebih kurang 13 ton dengan jumlah tersebut wisatawan sebanyak 119 orang. Sementara itu interaksi dinamik melalui analisis phase line memiliki keseimbangan stable focus dimana keseimbangan system jangka panjang akan dicapai melalui penyesuaian antara kedua kegiatan tersebut. Artinya bahwa peningkatan jumlah wisatawan hanya bisa dicapai jika kegiatan perikanan dikurangi., Coastal areas of North Sulawesi ar e world renowned for their marine biodiversity. Such an area is Lembeh Strait located in the city of Bitung which also serves for other activities such as port, fishing and tourism. Protecting same coastal areas for conservation and marine tourism will benefit both economically and ecological ly. However, when protec ted areas are intermingle with traditional fishing ground, the question of how these activit ies could co-exist becomes a crucial point. This study addr esses such an issue through a modeling exercise by means of bio-economic mode ling. Specifically, the objectives of the study are 1) to determine economic value of marine resource ini Lembeh Strait as well as the scenario if the strait is reserved as marine protected area; 2) to determine convergence-divergence mechanism between tour ism and fisheries activities and 3) to analyze policy implication associated w ith the implementation of MPA (Marine Protecting Area) in the area.

Judul: The model of capture fisheries management in the area of Bali Strait
Abstrak: The fisheries activity was being prime mover (around 80%) of the fishermen and the society economic in the area of Bali Strait. However, it would be very much trivial if the potency was not well managed and unable to give the prosperity for the fishermen society. The research purposes were to determine the level of fishermen prosperity, to forecast the production of major catch of fishes, to determine the level of fisheries business feasibility, to formulate the management of the capacity building for strategy of fisheries resources, and to build the management model of the area that guarantees the sustainability of fisheries development. The method used consisted of the level of prosperity analysis, forecasting analysis, business feasibility analysis, strategy analysis by using AHP, and model analysis by using SEM. The results of analysis showed that the level of fishermen prosperity in the area of Bali Strait was ‘moderate’ (total score=25.80). The production of lemuru tended to increase within the last several years and at the year of 2010 was forecasted to decrease 44,899.13 tonnes. The production of tongkol tended to decrease, and at the year of 2010 was forecasted to reach 2,035.30 tonnes. The production of layang also tended to decrease, and at the year of 2010 was forecasted to reach 1,967.01 tonnes. As the dominant fisheries business, purse seine one boat system (OBS), purse seine two boat system (TBS), gill net and ‘payang’ were very feasible to be developed in the area indicatively the values, NPV>1, IRR>6.25, ROI>1, and B/C Ratio>1. The development managed by the spesific institution establised by local governments (RK=0.284) was the right strategy of capacity building in order to manage the fisheries resources in the area. This specific institution roled to organize the fisheries resources conservation programs, to regulate the exploitation of fisheries resources based on local governments policy (SKB), to supervise selling price and fishing gears operation periodically, to provide the information centre of job opportunity and the vocational centre, and to facilitate the local revenue planning of the sector of fisheries. The management model of the area developed could fit some criteria such as goodness of fit (Chi-square, signifance probability, RMSEA, GFI, AGFI, CMIN/DF, TLI, dan CFII). The results of analysis of the model showed that some concerned components for sustainability guarantee of fisheries development in the area required were local market performance, export market performance, product supply of processing industry to the market, biodiversity, prosperity of fishermen, work force absorption of capture fisheries business and industry, growth of capture fisheries business, income of processing industry and tax.

Judul: Uji sifat listrik dan struktur kristal fotodioda ba0,5sr0,5tio3 dengan variasi pendadahan fe2O3
Abstrak: Ba0,5Sr0,5TiO3 (BST) thin film was doped by Ferium (Fe2O3) has been done with doping variation 2.5%, 5%, 7.5% and 10% above the substrate Si (100) p-type using chemical solution deposition (CSD) methods by spin coating technique at 3000 rpm for ± 30 seconds. Ba0,5Sr0,5TiO3 thin film made with 1 M concentration and the annealing temperature by 850oC. The results of current-voltage (I-V curves) characterization shows that the BST thin film and BFST are photodiodes. Electrical conductivity values BST and BFST thin films are in the range of semiconductor materials and obtain the electrical conductivity increased when the higher intensity light is used. The result of the dielectric constant increases with the addition of Fe2O3 doping. SEM results showed that the BST and BFST material is a thin film with thickness of the order 10-6 m. Result of XRD showed that BST and BFST is cubic.
