Abstrak: Wediombo Karst is part of Gunung Sewu Mountain Karst Area which had been decided as the world heritage since 1994 by the International Speleology Mac Donald British Cave Research Association. Due to its beautiful land- and seascape panorama, beautiful caves, and unique flora and fauna, this area is potential to be developed as ecotourism area. The objective of this research is to provide a model to develop Wediombo as Karst Ecotourism Area. The research was conducted in 3 steps, i.e. (1) identification of biophysics, socio-economics, socio-culture, legal review, and tourist typology; (2) analysis of demand-supply, cost-benefit priority, and area-zoning; and (3) model development. In identifications step, data was analyzed descriptively. Area-zoning was analyzed using micro-ROS method. Model was developed using AHP and SWOT (AWOT) analysis. The results showed that Wediombo Karst Area has many potential places to be developed as ecotourism area, including beaches, caves, forests, traditional agriculture, and mountain areas. In addition socio-cultural, socio-economics, and legal aspects as well as analysis of tourist typology; demand-supply, cost-benefit priority support the development of karst ecotourism. Micro-ROS analysis shows that Wediombo area spreads over zoning scale 1 to 6, suggesting the natural condition still dominant. Zone development priority analyses suggests that zone A (Wediombo Beach) is the first priority, followed consecutively by zone B (cave and beach), zone E (local culture), zone C (Lowo Cave), zone D (forest area) and zone F (roadside area, stretching from rural boundary to Wediombo Beach). The AWOT analysis shows that Strengths and Threats (S-T) are the main factor for development of strategy. These results suggest that ecotourism development strategy concern in diversification based on local community. The first priority for the development of ecotourism is education tourism, which is expected will derive community awareness on sustainability of the environment including local culture.

Abstrak: This research was located in South Morotai and South-West Morotai District.The objectives of this researchis to study carrying capacity and to establish model concept management small islands for ecotourisms sustainable used. Data and information were collected in participative term by used a questioner and field survey. Analysis methods consist of spatial analysis used geographycal information system and suitable area analysis, for modelling used software Stella 9,02. The small island areas zonation using ecology, economic, social and institution criterias could be divided into 3 management zones such as the center zone with of 1618 ha, used zone with widely of 12.412 ha, and buffer zone with widely of 32.381 ha. Whereas suitable area for ecotourism zone consist of coastal ecotourism for recreation tourism categories, marine ecotourism categories for snorcling tourism, marine ecotourism categories for diving tourism, marine ecotourism category for seagrass. Shore longs of recreation tourism 59.809 m with of carrying capacity is 2.353 person/day, snorcling tourism with widely area used 226 ha with percentage rate of coral cover community 42 % with of carrying capacity 7.624 person/day, diving tourism with widely area 1.248 ha with percentage rate of coral cover community 40% with of carrying capacity 39.942 person/day, seagrass tourism with widely area used 102 ha with percentage rate of seagrass cover 58 % with of carrying capacity 4.733 person/day. Management model KP2K MS2B for ecotourism sustainability base on environmental conservation of ecologycal small island with the primary point were archipelago small island, integration in percentage pattern of the diversity used rate and the naturalism of island, if the invironmental ecological was disturbed, it will influence the sustainability of carrying capacity and the ecotourisms demand will affected too.

Judul: Pemanasan Sekunder Reaksi Fusi Plasma dengan Menggunakan Radio Frequency
Abstrak: Plasma merupakan bentuk ke-empat dari materi setelah padat, cair dan gas yang terbentuk dari proses ionisasi gas. Plasma dapat digunakan dalam reaksi fusi, yaitu reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat sambil melepaskan energi. Untuk mendapatkan energi dari reaksi fusi, inti yang akan direaksikan harus dipanaskan pada temperatur yang sangat ekstrem tingginya. Salah satu cara agar dapat mencapai kondisi ini adalah memberikan pemanasan tambahan atau pemanasan sekunder kepada plasma dalam reaksi fusi tersebut. Nilai daya serap rata-rata ion Deuterium yang sesuai dengan selang nilai daya dari data ITER adalah daya yang menggunakan frekuensi 50 MHz sampai dengan 60 MHz. Dengan menggunakan frekuensi 60 Hz diperoleh nilai daya rata-rata yang diserap sebesar 1,235.10-12 W.
