"Di Indonesia, terdapat beberapa wilayah yang berpotensi untuk ditemukannya cadangan unsur tanah jarang (UTJ). Salah satunya di Pulau Bangka dan Belitung yang berasosiasi dengan keberadaan Tin Belt of Southeast Asia. Mineral pembawa UTJ di wilayah penelitian terdiri dari zirkon, monasit, dan xenotim yang berasosiasi dengan endapan timah plaser. Metode yang digunakan dalam penelitian ini terdiri dari analisis binokuler, sayatan tipis, sayatan poles, dan micro-XRF. Karakteristik monasit dan xenotim cenderung memiliki ciri yang hampir sama, sedangkan zirkon lebih mudah untuk dibedakan. Secara keseluruhan, komposisi zirkon di wilayah penelitian lebih dominan daripada monasit dan xenotim. M1 merupakan sampel dengan kandungan xenotim yang sangat tinggi. Berdasarkan jenis unsurnya, sampel penelitian lebih banyak mengandung unsur tanah jarang ringan (LREE) daripada unsur tanah jarang berat (HREE). Keterdapatan HREE yang cukup dominan ditemukan dalam sampel P1 dan M1.

In Indonesia, several areas have potential reserves of rare earth elements (REE). One of them is the Bangka Belitung Islands which are related to the existence of the Tin Belt of Southeast Asia. REE minerals in the research area consist of zircon, monazite, and xenotime that are associated with tin placer deposits. This study used several methods, such as binocular, thin section, polished section, and micro-XRF analysis. The characteristics of monazite and xenotime incline to have the same pattern, while zircon is easier to distinguish. Relatively, the research area has a prominent zircon than monazite and xenotime. M1 is a sample with the highest xenotime content. Based on the type of REE, the sample study conceived of more light rare earth elements (LREE) than heavy rare earth elements (HREE). The dominant HREE was just found in P1 and M1 samples."

"PPATS merupakan camat yang ditunjuk dan diberikan kewenangan untuk membuat akta autentik di daerah yang belum cukup terdapat PPAT. Masih tergabungnya pengaturan terkait kewenangan PPAT dan PPATS menyebabkan adanya kerancuan terkait apa saja aturan yang hanya mengikat PPAT dan apa saja aturan yang juga mengikat PPATS Terdapat 6 orang PPATS di Provinsi Kepulauan Bangka Belitung yang tersebar di 2 kabupaten yang justru memiliki jumlah PPAT yang lebih banyak apabila dibandingkan dengan 5 kabupaten lainnya yang tidak lagi terdapat PPATS. Penelitian ini dilakukan untuk menjawab pertanyaan terkait dengan tugas dan kewenangan PPATS di Indonesia menurut PP 37/1998 juga perubahannya, serta eksistensi PPATS di wilayah Provinsi Kepulauan Bangka Belitung. Metode penelitian yang digunakan adalah penelitian yuridis normatif, dengan tipologi penelitian yang berbentuk evaluatif yaitu menilai dan menguji suatu hal tertentu dengan memberikan rumusan peningkatannya, serta data yang digunakan adalah data sekunder yang didukung dengan data primer. Penelitian ini menyimpulkan bahwa masih tergabungnya aturan yang mengatur PPAT dan PPATS menyebabkan PPATS tidak optimal dalam menjalan kewenangannya. Eksistensi PPATS di Provinsi Kepulauan Bangka Belitung juga dinilai tidak lagi sesuai dengan kebutuhan dan kewenangannya. Saran yang dapat disampaikan adalah perlunya evaluasi dan perubahan hukum terkait pengaturan kewenangan PPATS, serta didalaminya pertimbangan-pertimbangan penunjukkan PPATS.

PPATS is a subdistrict head appointed and authorized to make authentic deeds in areas where there are not enough PPAT. The incorporation of regulations related to the authority of PPAT and PPATS causes confusion regarding what rules only bind PPAT and what rules also bind PPATS. There are 6 PPATS in the Province of Bangka Belitung Islands spread across 2 districts which actually have more PPATS when compared to the other 5 districts where there are no more PPATS. This research is conducted to answer questions related to the duties and authority of PPATS in Indonesia according to PP 37/1998 and its amendments, as well as the existence of PPATS in the Bangka Belitung Islands Province. The research method is normative juridical research, with an evaluative research typology, namely assessing and testing a certain thing by providing an improvement formulation, and the data used is secondary data supported by primary data. This research concludes that the incorporation of rules governing PPAT and PPATS causes PPATS not to be optimal in exercising its authority. The existence of PPATS in the Bangka Belitung Islands Province is also considered no longer in accordance with its needs and authority. The suggestion that can be conveyed is the evaluation and legal changes related to the regulation of PPATS authority, as well as deepening the considerations for the appointment of PPATS."

"Harga tanah semakin hari semakin meningkat. Harga tanah di setiap lokasi berbeda antara satu sama lain. Perbedaan harga tanah ini membentuk pola harga tanah. Pola harga tanah dipengaruhi oleh beberapa variabel diantaranya penggunaan tanah, aksesibilitas, jarak dari pusat kota dan jarak dari lokasi wisata. Penelitian ini bertujuan untuk mengetahui pola harga tanah dan mengetahui faktor yang paling berpengaruh dalam harga tanah di Pulau Belitung bagian barat. Penelitian ini menggunakan unit analisis zona nilai tanah yang digunakan oleh Badan Pertanahan Nasional pada penelitian terdahulu dan dilakukan pemodelan skoring serta pengalian angka indeks sebagai model untuk mendapatkan harga tanah tahun 2018. Untuk menentukan faktor yang mempengaruhi harga tanah dengan menarik garis grafik menggunakan jaringan jalan yaitu jalan arteri dan jalan lokal. Data yang digunakan berupa data sekunder penggunaan tanah, data zona nilai tanah terdahulu dan data jaringan jalan. Hasil penelitian ini menunjukkan bahwa semakin jauh dari pusat kota dan lokasi wisata, harga tanah semakin rendah. Harga tanah yang berada di jalan arteri lebih tinggi dibandingkan harga tanah yang berada di jalan lokal. Pusat kota dan lokasi wisata memengaruhi harga tanah namun harga tanah yang dekat dengan pusat kota lebih tinggi dibandingkan harga tanah yang dekat dengan lokasi wisata karena tingkat ekonomi di lokasi tersebut lebih tinggi dibandingkan di lokasi lain.

The land price is getting higher day by day. Land price in every location is different between another. Land price difference create land price pattern. Land price pattern is effected by some variable such as land use, accessibility, distance from city center and distance from tourist sites. This study aims to know land price pattern and to know which most influential factor in land price pattern in West of Belitung Island. This study use land price zonation from Badan Pertanahan Nasional from the previous study as analytical unit as scoring model and excavation index number to create model to get 2018 land prices. Defining factors that affect land price by drawing a graph line using road network which are arterial road and local road. Data used in the form of secondary data are land use, previous land price zonation and road network data. The results of this study indicate the further away from city center and tourist sites, land price is decreasing. Land price in arterial road is higher than land price in local road. City center and tourism areas affect the land price. Land prices that are closer to the city center are higher than land prices that are close to tourist sites because economic activity in that location higher than other location."

"The information on fish fauna in Belitung Island is still lacking. The study of ichthyofauna of Belitung Island was conducted in Pebruary-March 2002 and August 2003, using survey methods. The aims of studies are to know species richness, potency, local distribution, and related aspects. The results were recorded 60 species belonging to 27 families. Cyprinidae is dominant family with 13 species. The fishes were found almost have potency of ornamental fish. It was found that Eirmotus octzona, Acanthopsoides robertsi, Pangio shelfordii, Silurichthys hasseltii, Parakysis verrucosa, and Gymnochanda filamentosa extend their range to Belitung (new record for Belitung). Status, potency and utilization of fishes, new records distribution of geography, social economic and conservation aspects are represented in this paper. The information about freshwater fishes from Belitung Island is still rare. Last information was reported by de Beaufort in 1939. The objective of the research is to reveal the diversity of fishes in Belitung Island and to reveal their potency and utilization, distribution, abundance, and related aspect for their management and conservation. The research was conducted at Belitung Island, Province Archipelago of Bangka Belitung, between 2002 and 2003. Location of research in Lenggang River, Buding, Balok, Kembiri, Pala, and Air Raya Gunung Tajam. Survey method is used in this research. Specimens were collected from 21 location in six rivers by electrofishing (12 volt), gillnet (mesh size ½', ¾', and 1'), cast net, and hook. Fish specimens were fixed by using formalin 10% then soaked in alcohol 70%. All specimens are deposited at Museum Zoologicum Bogoriense, Bogor, as permanent collections. Fish identification was based on Weber and de Beaufort (1916; 1936; 1953; 1965), Inger & Chin (1962), Roberts (1989), Kottelat et al. (1993), and Eschmeyer (1998). In general, these established localities followed the variety of the landscape available such as: primary forest, secondary forest, 'kerangas' forest, agroforestry, villages, and estuary environments. Informal interview was conducted with the villagers especially with those who were familiar with fishing activities. There results were recorded 60 species belonging to 27 families. Cyprinidae is dominant family with 13 species. The fishes were found almost have potency of ornamental fish. It was found that Eirmotus octozona, Acanthopsoides robertsi, Pangio shelfordii, Silurichthys hasseltii, Parakysis verrucosa, and Gymnochanda c.f. filamentosa extend their range to Belitung (new record for Belitung). There were Tengkelesa'/Arwana (Scleropages formosus) in Lenggang River. According to the CITES, Tengkelesa' status is in Appendix I with a note captivity in Appendix II. Scleropages formosus has been protected by regulation, while according to the Governmental Legislation No.7 in 1999. Lenggang River is one of the largest water catchment area in Belitung Island. It has much more variation of riparian habitat than the other river. The number of species and family fish decreased closer to the river mouth. Factor which may influence this are the presence of plant material, the presence of a shading canopy, and the presence dam. The range of local distribution is 0,64-5,13%. Puntius gemellus is widest distributed and most abundanced. Segment of Lenggang River would conserve the continuing populations of Scleropages formosus. This habitat establishing small harverst reserves or fishery reserves (called 'Suaka Perikanan), where local community could manage this reservat could be perfomed. Activities related to this conservation habitat, controlled fishing activity or environmentally sound fishing should be encouraged. In line with the effort to increase individual income in the area, segment of the river from the mouth of the river could function as scientific and/ or adventurous tourism."

This research analyzes the Governance of Ecotourism Collaboration in Belitung Regency, Bangka Belitung Islands Province. Attention is paid to the study of collaborative governance which is considered one of the key issues for success in the context of Belitung tourism development as part of the UNESCO Global Geopark network. The contribution and role of each actor, whether from the government, private sector, society, or community, has made a positive contribution to build quality tourism that is sustainable and environmentally friendly. This research uses an qualitative methods research approach. In this research, data was obtained through in-depth interviews, document reviews, and surveys so the triangulation process could be carried out more completely. Research informants comprised elements from the government, private sector, associations, society, and community. A total of 13 informants were interviewed and 31 people provided answers to the survey conducted. The results of research on Collaborative Governance Practices that took place in Belitung Regency were initiated with program innovation and collaboration that developed from a bottom-up process spearheaded by the role of the Geosites Community and Tourism Village. Next, the results of this research have shown that trust, cultural values, and social networks perceived as social capital have become the glue and bind each actor to work together so that it functions as a basic element for forming good collaboration. This research confirms and complements the collaborative governance model initiated by Ansell and Gash. Based on research conducted, has shown that the role of social capital is the main factor that supports collaborative governance. If Ansell and Gash's collaborative governance model does not explicitly state social capital as the main factor in the collaboration process, this research has shown the role of social capital as a basis for collaborative initiatives. As one of the findings and novelty in this research, the author added one indicator to the dimensions of Initial Conditions and/or Collaborative Process by adding social capital background which includes norms or cultural values and social networks. which influences the implementation of collaboration."
