Judul: Perencanaan Wisata Alam di Pantai Bukit Batu, Kabupaten Belitung Timur, Provinsi Kepulauan Bangka Belitung
Abstrak: Bukit Batu Beach is one of beaches in East Belitong. Bukit Batu Beach has golden brown sandy beach, calm waves and rock formation along the shore. The existences of hill around Bukit Batu Beach differentiate this beach from other beaches on the East Belitong region. The manager of Bukit Batu Beach had not had any plan to develop the coast towards natural tourism yet. Therefore, a study on the planning of natural tourism was required to support natural tourism in Bukit Batu Beach. The research was conducted at Bukit Batu Beach in July -August 2012. Instruments, used in the research were questionnaires, scoring table and interview guides. Respondents were managers, local people (93 respondents), and visitors (60 respondents). Data were gathered through literature review, interviews and field observations. Data were analyzed using a modification of Natural Tourism Objects and Attractions Assesment of develop by PHKA on 2003, known as ODTWA and descriptive analysis. Attractions and accessibility assessment using the ODTWA showed four objects with high value classification, namely Malang Lepau Beach, Malang Lepau Hill, Batu Bertumpuk, Malang Lepau Inlet. There were sociocultural potential of the communities around Bukit Batu Beach which include ethnic diversity, religious diversity, traditional dances, folklore of Anchors Belitung Island, Sea ceremonial salvation, Kwan Im temple, Bugis traditional houses and typical crafts of Burong Mandi village. Visitors of Bukit Batu Beach was dominated by teenagers (65%) and male (62%). The manager planed to build asphalt roads and a swimming pool in Bukit Batu Beach. The concept of planning in Bukit Batu Beaches was a tourism planning with the principle of conservation in order to maintain the growth natural resources in accordance with the ecological functions and to keep the function of the site. Planning of nature tourism in Bukit Batu Beach was based on the ecology. The ecological based planning of nature tourism in Bukit Batu Beach consis of spaced, accessibility, circulation, activities, facilities and human resource planning. Spatial planning consisted of divided the area into three spaces that were tailored to the priority object and field conditions. The first area was the main tourist space, which served as the center of visitors activities with high spatial use intensity. Main tourism space did not require too much modification resources to support the planned tourism activities. The second area supporting tourism space which was design to overcome visitor accumulation was in the main tourism space. In this area there were would be more recreational activities that still kept the educational value in it, namely tracking and Macaca watching. The additional supporting tourism space which was as the space support facilities in Bukit Batu Beach. The planned concept of accessibility was the addition of signposts and traffic signs along the way to Bukit Batu Beach. Circulation type in Bukit Batu Beaches were specified to a ecological – based beach destination, that the planned circulation path was divided into pedestrian and bike/wagon path and was not intended for motor vehicles. Planned activities and facilities were adapted to the natural resources, taking into account the consist of the environment, thereby minimizing damage to

Judul: Perencanaan pariwisata alam berbasis data spasial di Taman Nasional Bukit Barisan Selatan
Abstrak: The National Park of Bukit Barisan Selatan (TNBBS) was declared as “Cluster Natural World Heritage Site” at 2004. The declaration will support a sustainable nature-tourism utilization. Development of nature tourism at TNBBS is concentrated in Kubu Perahu and Sukaraja Atas area. Objective of the research is to develop a plan of nature tourism based on spatial data. The research proposed application of planning model, proposed by Gunn (1994) which is combined with ADO-ODTWA (Analisis Daerah Operasi Obyek dan Daya Tarik Pariwisata Alam) promoted by PHKA (2003b). Spatial analysis was done with Arcview 3.3. The overlay spatial analysis proposed a prime and support criterias. Prime criteria consist of habitat fragility, soil, rainfall and slope sensitivity, the attraction of nature phenomena and wildlife. Support criteria is the potential accessibility. The result of the spatial analysis showed that Sukaraja Atas and Kubu Perahu have two categories of nature tourism area that is medium intensity tourism area and low intensity tourism area. Sukaraja Atas area have 483.8 hectare (71.2%) of medium intensity tourism area and 195.4 hectare (28.2%) of low intensity tourism area. Kubu Perahu area have 374.9 hectare (32.7%) of medium intensity tourism area and 771.0 hectare (67.3%) of low intensity tourism area.The result of the reoverlay between the classification map and the maps of each criterias showed that the spatial analysis which were used in this research had capability to bounding the tourism development based on resources sensitivity (showed the importance of conservation) and supported the resources potencies to gave the recreational value. Spatial system at Sukaraja Atas and Kubu Perahu had 2 (two) areas, (1) Low intensity tourism area and (2) Medium intensity tourism area. The wide of each areas be the same with the wide of the classification result. The main facility is an interpretation trail that have fungtion as a connector the visitor to the attraction site and inter-site of attraction. The setting of the interpretation trails more priored in the medium intensity tourism area. Development of nature tourism in the areas for low intensity tourism have purpose as a connection interarea for medium intensity tourism and give an attraction opportunity which have special quality for challenge variance. Facility development in the areas for low intensity tourism were finited for an interpretation trail and nature shelter. Trail development in steep areas must pay attention with visitor’s safety with stepsmaking, however the steps must built from nature material and specific wide to minimization soil-clearing and a distrubance to animal movement. The conclution of this researh, first, spatial analysis which were used in this research had capability aimed at the importance of conservation and gave the recreational value. Second, spatial system at Sukaraja Atas and Kubu Perahu consist of the low intensity tourism area and medium intensity tourism area. Third, management variation of nature tourism with spatial system and a plan of facility can make variation of nature-tourism opportunity especially variation of interest, variation of visitors, variation of spend time and variation of interpretation.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
