Judul: Strategy and development program of marine tourism in Natuna Regency
Abstrak: Natuna Regency, located in the province of Riau Islands, has a great potential for the development of nature tourism and marine tourism. Currently the potential in this sector has not contributed significantly to the region development. The largest revenue of Natuna’s is from the fund balance of 90.53 percent, which is mostly obtained from the shared profits of oil and gas. Natuna’s dependence on oil and gas is very vulnerable and can not continuously be maintained because these natural resources of oil and gas has a certain period of time and can not be renewed, so the natural resources for tourism can be an alternative source of regional revenue (PAD) and a sector that can contribute to economic growth, job creation, and poverty reduction and then become the development priorities in Natuna regency in the future. At present, the tourism sector in Natuna is undeveloped, not yet focused on one location and there is no appropriate strategy and development program of marine tourism to be implemented. However, Natuna has a great potential for the development of marine tourism, i.e., there are eight potential locations for the development of marine tourism. The objectives of this study were 1) to identify the location of marine tourism objects to be prioritized for development, 2) to examine the internal and external factors of development marine tourism in Natuna regency, 3) to formulate alternative strategies in the development of marine tourism in Natuna, 4) to determine the strategies and programs that can be implemented by the local government to develop marine tourism in Natuna regency. The study used the analysis of Respondents Perceptions Index on four factors: Attractions, Amenity, Accessibility and Ancillary; Internal and External Analysis (IFE - EFE), SWOT Analysis; and QSPM Analysis (Quantitative Strategic Planning Matrix). The results of the questionnaire data processing showed that the location of the marine attraction to be the first priority for development is the Gulf Coast of Selahang because it has quite good tourist attraction and the best accessibility compared to other locations. The second priority is Senoa Island because it has a good tourist attraction but the transportation accessing to the site and tourism supporting facilities at this location are not yet available. Further, the analysis of internal factors indicated that the greatest strength is the potential of attractive nature tourism and marine tourism that can be developed to provide economic benefits for the people of Natuna Regency, while the greatest weakness is the limited supporting tourism infrastructure and facilities, thus requiring some improvement in the prioritized locations. Next, the external key factor as the biggest opportunity is a government policy that motivates the regional tourism programs expected to encourage the development of marine tourism in Natuna regency, while the greatest threat to the development of marine tourism is the access to the Natuna Regency, which is still difficult. 6 From the resulted analysis of internal and external factors through the IFEEFE and SWOT matrix, six alternative strategies were formulated. Then, from the results of QSPM analysis, a sequence of priorities was obtained, namely: 1) to facilitate accessibility

Judul: Tunda Island Marine Tourism Development Strategy with Coastal Resources Natural Resources Approach, Serang Regency, Banten.
Abstrak: Tunda Island is a small island that has accessible resources, inaccessible resources, and environmental services that are potential for development in the marine and fisheries sector. Ecosystem environmental services are utilized in tourism activities with the concept of ecotourism. The development of ecotourism has been going on for decades worldwide, especially in tropical areas with coastal assets such as corals, mangroves and beaches. Information in the form of suitability studies and strategies for the use of mangrove ecosystems, coral reefs and beaches as objects of ecotourism needs to be examined to see if natural resources have not been used effectively and optimally as tourist objects. The suitability study needs to be accompanied by a study of each regional activity carrying capacity to maintain the sustainability of natural resources. The methods used in collecting ecological data are water passes for slope beaches, transect quadrat and spot check to identify mangrove, Underwater Photo Transect (UPT) for identifying coral reefs, and Underwater Visual Census (UVC) for identifying reef fish. The collection of economic data is carried out on tourists, while the collection of social data is carried out to several stakeholders organized both at the local community level, up to the province of Banten. To formulate the Tunda Island marine tourism development plan, it used spatial analysis, carrying capacity analysis, economic analysis, and strategy analysis are used using the Hierarchy Process Analysis (AHP). The tourism potential that can be developed is the potential for beach tourism, mangrove tourism potential, snorkeling tourism potential and diving tourism potential. The carrying capacity of beach tourism is 776 people/day, mangrove tourism is 80 people/day, snorkeling tours are 562 people/day and diving tours are 587 people/day. The economic value of willingness to pay by tourists or Willingness to Pay (WTP) is IDR 21 056 198 per year. The key stakeholders of Tunda Island marine tourism are Dinas Kelautan dan Perikanan (DKP) Banten Province and Kelompok Sadar Wisata (POKDARWIS) Tunda Island. The marine tourism development strategy of Tunda Island was arranged using AHP analysis. Developing the marine tourism strategy of Tunda Island was based on ecosystem management priorities by improving the ecosystem, considering carrying capacity, conducting rehabilitation, monitoring and evaluation of ecosystems, improving infrastructure facilities, increasing capacity and empowering communities, integrated management between stakeholders and improving facilities and infrastructure.

Judul: Pemodelan Dinamika Glukosa dengan Persamaan Hovorka menggunakan Metode ODE 45 untuk Kasus Diabetes Tipe 1.
Abstrak: Type 1 Diabetes is a case where beta cell in pancreas cannot produce insulin properly. On a type 1 diabetes case, some insulin had to be added into the bloodstream. This simulation used Hovorka equations and ODE 45 methods in MATLAB. To know the amount of dosage for insulin that a type 1 diabetes case need, also how the kinematics and dynamics look like for the glucose rate in the bloodstream can be done by using this simulation. Some variation on the amount of insulin, injection time and weight had been done to get the optimum result of glucose rate in the bloodstream. The result from this simulation is a 70 kg weigh need insulin injection in the morning for about 2 dL, and 21 dL each for afternoon and night times, all of injection time is an hour after eating.
