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.

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: Validation method for determination of apigenin in extract celery with high performance liquid chromatography
Abstrak: Apigenin is an active substance derived from celery (Apium graveolens) and widely used for the treatment of gout. Determination method of apigenin which have been validated was introduced by Frankee et al. J Food Compos Anal 17: 1-35 (2005). Apigenin analysis was done by high performance liquid chromatography (HPLC). To make sure that HPLC analysis method can be used for the intended purpose then the method was validated. Parameters determined on method validation were linearity, limit of detection, limit of quantification, precision, and accuracy. All parameters were in accordance with the acceptance criteria of Association of Official Analytical Chemist. The linearity in the concentration of 3,8; 5,7; and 7,6 mg/l had correlation coefficent of 0,9900–0,9998. limit of detection in this method was 2,7222 mg/l and limit of quantification was 8,2500 mg/l. Interday precision in five restating showed good precision with relative standard deviation of 3,85%. Accuracy was determined by standard addition method with recovery percentage of 95,00–118,77%. Average concentration of apigenin is 0,0052% (w/w).
