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: Sintesis Paduan Ti-6Al-4Nb sebagai Matrial Implan Pengganti Komponen Tibial
Abstrak: Synthesis of Ti-6Al-4Nb alloy was done by melting using Tri Arc Melting Furnace. Each sample was remelted five times to ensure the homogenity. Aluminum and niobium addition were expected to stabilize α phase and β phase until the αβ-titanium alloy was resulted. Yet based on the experiment, it was α-titanium alloy resulted. α-titanium alloy was a Hexagonal Close Packed (HCP) crystalline structure which would be cracked if deformation non-uniaxial happens. The presence of oxygen in pure titanium significantly increased the hardness of titanium. The addition of aluminum was also able to increase the hardness of titanium alloy because aluminum more stabilize the α phase in the α-titanium alloy. The corrosion ressistance of titanium could be increased by adding aluminum and niobium. Titanium coating with HA/chitosan composite was also proved in decreasing the corrosion rate because it barried direct interaction between titanium alloy and corrotion solution.
