Judul: Analisis permintaan dan strategi pengembangan wisata bahari di pulau Sebesi, kabupaten Lampung Selatan, provinsi Lampung
Abstrak: Kawasan Konservasi Laut (KKL) merupakan suatu daerah di laut yang ditetapkan untuk melestarikan sumberdaya laut. Kawasan Konservasi Laut memiliki daya tarik berupa keindahan ekosistem terumbu karang yang ada di dalamnya. Hal tersebut dijadikan peluang untuk meningkatkan pariwisata bahari di KKL. Salah satu wilayah yang memiliki keindahan alam dan keanekaragaman flora dan fauna adalah Pulau Sebesi yang dijadikan Daerah Perlindungan Laut Berbasis Masyarakat (DPL BM). Penelitian ini bertujuan untuk mengidentifikasi karakteristik wisatawan yang berkunjung ke Pulau Sebesi, menganalisis fungsi permintaan rekresi di Pulau Sebesi, menganalisis surplus konsumen yang dihasilkan kawasan wisata di Pulau Sebesi, dan merumuskan strategi pengembangan wisata bahari di Pulau Sebesi.

Judul: Marine Ecotourism Development Strategy with Coral Reef Ecosystem Valuation Approach on Sebesi Island, Lampung
Abstrak: Ekosistem terumbu karang dapat memberikan jasa ekosistem terhadap masyarakat sekitarnya, namun seiring dengan kebutuhan ekonomi yang tinggi, tekanan terhadap ekosistem terumbu karang juga semakin besar. Bentuk pengelolaan pesisir yang mengutamakan kelestarian dan keberlanjutan sumberdaya adalah wisata bahari dengan pendekatan valuasi ekosistem terumbu karang. Aktivitas wisata yang dapat dijumpai di Pulau Sebesi adalah wisata pantai, snorkeling dan diving. Semula potensi tersebut memberikan dampak baik bagi masyarakat Pulau Sebesi, namun akhirnya terlihat adanya pemanfaatan yang berlebihan dan kurang terkontrol kepada sumberdaya di Pulau Sebesi. Berdasarkan hal tersebut dilakukan penelitian dengan menganalisis kesesuaian wisata dan daya dukung kawasan untuk kegiatan ekowisata bahari dengan objek wisata terumbu karang, menganalisis nilai ekonomi ekosistem terumbu karang untuk wisata, dan selanjutnya dirumuskan strategi pengelolaan ekowisata bahari di Pulau Sebesi. Penelitian ini dilakukan mulai November 2020 hingga September 2021 di Pulau Sebesi Kabupaten Lampung Selatan, Provinsi Lampung. Pengambilan data primer dilakukan secara in situ meliputi data kualitas perairan, data sumberdaya terumbu karang, dan sosial ekonomi. Data sekunder didapatkan dari studi literatur. Data yang telah diperoleh, kemudian dianalisis dengan menggunakan analisis Indeks Kesesuaian Wisata (IKW), Daya Dukung Kawasan (DDK), Travel Cost Method (TCM) dan analisis SWOT. Hasil penelitian menunjukkan bahwa lokasi studi yang sesuai untuk pengembangan ekowisata bahari kegiatan snorkeling adalah Pulau Umang dan Kebon Lebar dengan daya dukung kawasan wisata sebanyak 290 orang/hari. Kemudian, lokasi yang sesuai untuk pengembangan wisata bahari kegiatan diving adalah Pulau Umang dan Gosong Sawo, dengan daya dukung kawasan wisata sejumlah 191 orang/hari. Estimasi nilai ekonomi terumbu karang eksisting di Pulau Sebesi adalah sebesar Rp. 1.575.729.760/tahun untuk kawasan terumbu karang yang sesuai untuk aktivitas wisata diving dan snorkeling. Selanjutnya, strategi pengelolaan wisata bahari snorkeling dan diving di Pulau Sebesi dapat dirumuskan menjadi enam strategi yaitu, 1) Optimalisasi daya dukung kawasan melalui pemasaran; 2) Pengadaan biaya tiket untuk pengembangan sarana prasarana; 3) Penerapan kebijakan operasional ramah lingkungan; 4) Efektivitas program konservasi terumbu karang; 5) Penguatan peraturan dan kelembagaan; 6) Meminimalisasi timbulan cemaran., Coral reef ecosystems can provide ecosystem services to surrounding communities, but along with high economic needs, pressure on coral reef ecosystems is also getting bigger. The form of coastal management that prioritizes the sustainability and sustainability of resources is marine tourism with a coral reef valuation approach. Tourism activities that can be found on Sebesi Island are beach tourism, snorkeling, and diving. Initially, this potential had a good impact on the people of Sebesi Island, but finally, there was a pattern of excessive and uncontrolled use of marine biological resources on Sebesi Island. This research was conducted to analyze the suitability of tourism and the carrying capacity of the area for marine ecotourism activities with coral reef tourism objects, analyze the economic value of coral reef ecosystems for tourism, and then formulate a strategy for managing marine ecotourism on Sebesi Island. This study was conducted from November 2020 to September 2021 on Sebesi Island, South Lampung Regency, Lampung Province. Primary data collection was carried out in situ, including water quality, coral reef resources, and socioeconomic data. Secondary data was obtained from literature studies. Data were analyzed using the Tourism Suitability Index (IKW), Regional Carrying Capacity

Judul: Effects of Particle Shapes on Temperature Distribution under Static Ohmic Heating.
Abstrak: The ohmic heating is defined as a process wherein an alternating electrical current is passed through materials resulting in the heat generation inside the product. The excellence of ohmic heating in comparison with other thermal processing is its energy efficiency and ohmic heating could keeping nutritional as well quality attribute of food via blanching, sterilization, pasteurization, extraction, fermentation, and evaporation. Nevertheless, in ohmic heating process, the electrical conductivity of product is a key parameter. The worst case in the ohmic heating of multiphase product could be occurred when the solid phase has very lower or very high electrical conductivity than the liquid. This study aims to reveal the temperature distribution and the heating rate properties of solid and liquid phase as affected by particle shape and its orientation to the electric field. Experiments were conducted with salt solution 1% and carrot that blanched in salt solution 6%. Blanching process was conducted in order to increase the electrical conductivity of carrot close to the salt solution 1%. Ohmic heating was applied to the sample using static cell (4.90 cm diameter and 6.00 cm in length of sample area) at constant voltage gradient (40 V). Each experiment was conducted in triplicate. It was observed that the different particle shape and orientation provide the different heating rate properties. The slice particle had the fastest heating rate. Moreover the perpendicular orientation was heated faster than parallel orientation. The parallel cylindrical shape provides the slowest heating rate. This shape possibly induced the worst-case condition and could be used as sufficiency heat parameter. The heating pattern of each solid and liquid were simulated using COMSOL modeling software. The predicted temperature values were in good agreement with the experimental data with the maximum prediction error of 3 °C.
