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: Pengembangan Wisata Bahari Dalam Pengelolaan Sumberdaya Pulau-Pulau Kecil Berbasis Ekologi: Studi Kasus Pulau Sebesi Provinsi Lampung
Abstrak: Sebesi Island is the one and only island in the vicinity of Mount Krakatau which can be inhabited. Sebesi Island has the potenticy to be developed as a tourist destination object, based on ecology. Research on the Development of Marine Tourism-Based Small Islands Ecology: Case Studies Sebesi Island in Lampung Province aim to assess the suitability of Sebesi Island area for marine tourism activities based on the ecology of diving and snorkeling, to analyze the carryng capacity Sebesi Island for marine tourism activities with ecology based, and to formulate strategies and policy direction in the development of marine tourism on the Sebesi island. The primary data were collected through sampling, direct observation of field conditions, distributing questionnaires, interviews, open/direct and in-depth interviews at the sites. The secondary data were collected by tracking the various libraries, and related agencies. The result showed that the kind of ecology-based marine tourism activities categories of diving and snorkeling were included in the appropriate category (S2) to the Sebesi Island. Carrying capacity for diving activity was 2,394 person and snorkeling was 2,489 person. According to A’WOT Analysis which is Integrated tourism management, Strengthening regulatory and institutional, Increasing human resources, Community empowerment, Efforts to prevent damage to coral reefs and Utilization and management of coral reefs.

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.
