Judul: Cluster-based capture fishery development model in Ambon City
Abstrak: Ambon City is located in the southern part of Ambon island which is surrounded by the Banda Sea and the Maluku Sea. This city consists of marine areas (52%) and 32 coastal villages which do not have sufficient land-based natural resources, either plantation or mineral resources or mining. Although economic growth of the city was highest for 5 years, poverty is still one of big issues for these coastal villages. This research was designed to provide a model of village-level fisheries development using clustering approach. In this model, villages are grouped into six clusters based on the fisheries development status of the village, the feasibility of fisheries business units, access to market networks, and level of business ownerships. This study also examined some potential factors of fisheries development. Working capital, coral reefs, fishing fleets, all factors in the socio-cultural dimensions, and facilities and village infrastructure require no special attention due to their insignificant effect on the financial performance of fisheries business. Meanwhile, as common in four of the six clusters, topography and demography, settlement, and business profits need some attentions. Factors that should be developed in four clusters are fishing gear, return on investment, and business continuity. AHP indicates three important policies that are common among clusters. These are related to issues on potential resources of fish, accommodating regulation or law, and technology support. Issues on technical development is a priority interest in the majority of the clusters, followed by issues on prospective market, and fisheries infrastructures. Finally, the most prioritized strategic policies for the development of coastal fishing village in Ambon is the promotion and development of human resources. It shows that local stakeholders seriously consider good quality human resources as one of success keys of marine and coastal resources utilization and a strategic instrument to sistematically reduce poverty of coastal villagers. Linking the various elements or phenomena or variables in this study, established in propositions that make up a model. Model-based development of fishing industry cluster villages in Ambon city is named Model Manggurebe Maju. Term in the local language can be interpreted as an effort to move forward.

Judul: Model of management of capture fisheries area in Banten Bay
Abstrak: Banten Bay is area which quite rapid development for many activities. Industrial waste disposal, domestic, over fishing, coral exploitation, reclamation, vessel traffic, and environmental damage, cause interest multi sector conflict in managing sea area. General objective of the research is to create model of management of sustainable capture fisheries area in Banten Bay. The specific objectives are to (1) determine utilization status and development prospect of capture fisheries; (2) determine leading commodity; (3) determine environmentally friendly fishing gears, (4) establish utilization zone; (5) arrange policy strategy in managing capture fisheries; and (6) simulate of model of management of capture fisheries. Evaluating utilization status and development prospect of capture fisheries was conducted using surplus production method with bionomic model. Determination of leading commodity was conducted with LQ value, IS, and descriptive method. Environmental and sustainable fishing gear was analyzed using CCRF criteria with scoring method approach. Zoning of capture fisheries area utilization was conducted by GIS. Management strategy of capture fisheries area was conducted with SWOT and AHP. Simulate of model of management of capture fisheries was conducted with LGP and model simulation of sustainable fish resources and salary fisherman. The result showed that utilization status and development prospect of capture fisheries in Banten Bay can still be developed for 9 species from 23 species. Squid, anchovy, and crab were commodities with high comparative advantages. Hand line, boat lift net, and gillnet were environmentally fishing gears. Zoning of Banten Bay utilization are consist of aquaculture, recreation, conservation, capture fisheries, fishing port, and industrial zone. Zone of capture fisheries was composed base on fishing ground eligibility indicator, suitability of fishing gear with fishing ground, minimum of conflict potency, availability of infrastructure, and environmental carrying capacity. Capture fisheries zone is divided into three zones, that are (i) passive zone, (ii) passive and outboard fishing boat zone, (iii) active and inboard fishing boat zone. Based on LGP analysis, maximum catch was 1.747,259 ton/year, alocation for fishing gear of gillnet, danish seine net, set lift net, boat lift net, boat seine, hand line, guiding barrier trap, and monofilament gillnet were 3, 11, 11, 6, 2, 5, 0 and 0 unit, respectively. The proposed strategy in managing Banten Bay area were (1) utilization strategic location of Banten Bay with optimalization leading commodity for providing fish demand; (2) taking advantage of high availability of human resources and fisherman concern to manage capture fisheries area; (3) utilization local government support and regional autonomy to make policy in structuring and expansion of fishing area and involving coastal communities in the management. Model of management of capture fisheries area in Banten Bay can be increase of salary fisherman as much as 25% from first scenario and take care of sustainable fish resources the periode of time 18 years.

Judul: Test of Optical and Electrical Properties of Thin Film Strontium Titanate (SrTiO3) Doped with Lanthanum Oxide (La2O3) with 0%, 2%, 4%, and 6% Exposure Variations
Abstrak: Film tipis Stronsium titanat (SrTiO3) telah berhasil dibuat dengan menggunakan metode Chemical Solution Deposition (CSD) dan Spin Coating. Dalam penelitian ini telah dibuat film tipis Stronsium titanat (SrTiO3) didadah Lantanum oksida (La2O3) dengan variasi pendadah 0%, 2%, 4%, dan 6%. Film tipis tersebut ditumbuhkan di atas substrat silikon tipe-p (100). Film tipis SrTiO3 melalui tahap annealing pada subu 850ºC ditahan selama 8 jam dengan kelajuan kenaikan suhu sebesar 1,67 ºC/menit, kemudian mengalami proses pendinginan 12 jam. Film tipis SrTiO3 didadah La2O3 (0%, 2%, 4%, 6%) dikarakterisasi sifat optiknya dengan menggunakan Spektrofotometer UV-Vis dan sifat listriknya dengan menggunakan LCR meter. Energi bandgap yang dihasilkan film tipis yang dibuat pada penelitian ini secara berurutan adalah 3,48 eV; 3,23 eV; 3,75 eV; dan 3,18 eV. Nilai konduktivitas film tipis SrTiO3 mengalami kenaikan siring dengan bertambahnya intensitas cahaya yang diberikan. Uji sensitivitas film tipis menghasilkan nilai perubahan tegangan (respons) yang dihasilkan menurun seiring dengan berkurangnya konsentrasi pendadah.
