ABSTRACTDecentralization has opened up the opportunities for foreign investors to devote theircapital for developing industrial sector after the free market agreement. The adoption ofnatural resource-based economic development policies by local governments encouragespeople to mine freely and massively, that followed by poor mining management of tonminerals. A number of studies on extractive industries are categorized into twoperspectives, namely institutional perspective, and political economy perspective.Institutional perspectives emphasizing on natural resource governance and the existenceof rent in the institutional governance system. Meanwhile, the political economyperspective tend to focus on how the ruling class accessing and controlling naturalresources followed by the act of extraction rent. This study uses a political economyperspective from the Veltmeyer and Petras concepts of new extractivism. This studyexplains the capital penetration on tin mining with the role of the patronage network oftin collectors in the process of capital accumulation and explains the other forms of naturalresource conflict. By using case studies in Bangka Regency related to tin mining, thisstudy argues that new extractivism in tin mining is increasingly developing due to thesupport of extractive capital that is disseminated by the industrial elite to the tin collectornetwork, followed by conflicts of interest over the control of tin mineral resources byindustrial elite. This research uses qualitative case study method. Data collectiontechniques used observation, in-depth interviews, literature review, and secondary data.Informants of this study ranging from tin collectors, tin entrepreneurs and smelters,owners and miners of unconventional mines, Walhi Bangka Belitung, JATAM, expertresearchers and Bangka Regency Civil State Apparatus."

"This dissertation discusses about the tin mining in Bangka community in Penagan village, Province of Bangka-Belitung Islands, particularly on relations of strength in the activity structure of tin mining performed by the miners (individuals or groups) in organizing the control, exploitation, management and distribution of the resources in the area. Tin mining activities performed by Bangka people in Penagan is called TI forming inseparable part of Bangka people life. In these activities, the miners are connected in the context of relation of power based on the strength of each miner. The relation of strength and powers is not only demonstrated by the statue and role between Boss and subordinates in TI activities but also among TI with other miners interested in tin resources.In this dissertation, i will show the relation of power in the social structure being the function of mutual relations of strength among the miners based on the capabilities and capacity of each miner in such structure. The powers of each miner includes capital and symbols of relaionship regularly reproduced to strengthen the existing relation. Mutual relation is functionally empowered by the miners to maximize the economic benefit from available resources in the walks of life of the ccommunity. Tin mining structure is a siymbiotic and mutual cooperation network (mutual and profit exchange) primarily among the miners based on economic benefit of tin resource, where the fund will then become collective standard of the miners and business groups. The strength held by each miner in the context of tin resources control and tin mining activities indicate no dualism of the strength of the miner binding of free. In term of mining context, the existing strength is independent or binding. There is no miner who can directly control by the power it owns in tin mining activities. This is attributable to the fact that tin, as a resource in social system of tin mining is considered as collective resources.Research methodology used in this dissertation is qualitative research method with observation technique and in-depth interview. Specifically, it uses ethnography method resulth in deep and holistic examination on tin mining performed by Bangka community in Penagan. The period of data collection began from the early 2005 until August 2006. I use the approach referring to the relations of power and strength among the miners in the tin mining structure which includes control, management and organizing of tin resources. The relation of powers among the miners is based upon the strength of the miners to influence and or to control other miners."

"Kabupaten Bangka Tengah, Provinsi Kepulauan Bangka Belitung terdapat banyak aktivitas pertambangan timah setiap tahun yang menghasilkan kolam- kolam air bekas pertambangan timah atau “kolong” yang tersebar dan terus bertambah banyak. Namun, penelitian mengenai pemanfaatan air kolong pertambangan timah belum tersedia, sehingga kajian pemanfaatan air kolong perlu dilakukan. Air kolong diidentifikasi tahun 2015 dan 2023 di Kabupaten Bangka Tengah berdasarkan Sentinel-1 SAR melalui GEE. Empat puluh sampel air kolong diuji kualitas air di lapangan. Penentuan prioritas pemanfaatan air kolong menggunakan AHP dan MCA berdasarkan luas air kolong, kualitas air kolong, jarak dari permukiman, jarak dari fasilitas umum, dan jarak dari pertanian. Hasil penelitian menunjukkan bahwa luas kolong terkecil terdeteksi dua hektare. Jumlah air kolong di Kabupaten Bangka Tengah tahun 2015 dan 2023 masing-masing sebanyak 114 dan 137 air kolong. Lebih dari 35 persen kolong memiliki luas lebih dari 5 hektare. Total luas kolong tahun 2015 tercatat 2005 hektare dan tahun 2023 meningkat menjadi 2215 hektare. Kedua, pH dari tiga sampel air kolong 11, 15, dan 40 memenuhi standar kualitas air bersih. Hampir seluruh sampel air kolong di Kabupaten Bangka Tengah rendah dan memiliki nilai pH sebesar 3 – 6,49. Dua sampel air kolong 14 dan 18 rendah dan memiliki nilai oksigen terlarut sebesar 3,3 dan 1,2 mg/L. Ketiga, para pakar mempertimbangkan kualitas air kolong lebih penting daripada variabel lainnya. Kawasan prioritas pemanfaatan air kolong di Kabupaten Bangka Tengah yang sangat sesuai sebesar 1209 hektare menjadi pertimbangan perencanaan pemanfaatan air kolong untuk memenuhi keperluan air bersih masyarakat.

Tin mining activities in Bangka Regency, Bangka Belitung Island Province produce ex-tin mining ponds or "Kolong". It is scattered and increases yearly. Kolong usage research is not provided, hence the research needs to be fulfilled. Kolong was identified in 2015 and 2023 in Bangka Tengah Regency based on Sentinel-1 SAR through Google Earth Engine (GEE). Forty water samples for water quality were measured in the field. Determining priorities for kolong usage uses AHP and MCA based on the kolong area, water quality in kolong, settlements distance, public facilities distance, and agriculture distance. The research results show the smallest pond detected was 2 hectares. The number of kolong in Bangka Tengah Regency in 2015 and 2023 are 114 and 137 kolong. More than 35 percent of ponds have areas of more than 5 hectares. The total area of the pond in 2015 was identified at 2005 hectares and 2215 hectares in 2023. Second, the pH of three water samples (11, 15, and 40) are clean water quality standards. Almost all water samples in Bangka Tengah Regency have pH in low (3 – 6.49). The DO of two water samples (14 and 18) is not high (3.3 and 1.2 mg/L). Third, the experts consider that water quality in Kolong is more important than other variables. The priority area for kolong usage in Bangka Tengah Regency is very suitable at 1209 hectares, which is the consideration for planning the kolong usage for the society."

"ABSTRACTSkripsi ini membahas dampak kebijakan ekspor timah di Kabupaten Bangka Barat, dengan melakukan studi terhadap Peraturan Menteri Perdagangan Nomor 32 Tahun 2013. Permasalahannya, setelah kebijakan diimplementasikan, masyarakat penambang tidak dapat menjual bijih timahnya. Penelitian ini menggunakan pendekatan kualitatif. Hasil penelitian ini kebijakan ekspor timah di Kabupaten Bangka Barat berdampak pada tiga komponen, yakni pemerintah, swasta, dan masyarakat. Bagi pemerintah daerah, kebijakan ini berdampak pada penurunan pendapatan. Bagi pihak swasta, yakni smelter timah dampaknya adalah tak dapat mengekspor timah secara langsung, karena harus melalui Bursa Komoditi dan Derivatif Indonesia (BKDI). Bagi masyarakat penambang, berdampak pada tidak dibelinya bijih timah oleh smelter.

ABSTRACTThis thesis discusses the impact of policy of tin export West Bangka Regency, through Regulation of Ministry of Trade No. 32 Year 2013. Its problem is after the policy is implemented, miners cannot sell their tin ore. This research used a qualitative approach. The results of this research has impact on three components, namely the government, private, and community. For local government, this policy resulted the decreasing of income. For private, namely the tin smelter, they can not export tin directly, because it must pass through Indonesia Commodity and Derivatives Exchange (ICDX). For the miners, the impact is the tin ore cannot bought by smelter."

"Ekstratksi tin dari sumber sekunder terbukti menjadi alternatif yang atraktif melihat dari permintaan produksi timah yang terus bertumbuh. Terak timah, yang tergolong sumber sekunder, masih menyisakan timah oksida sekitar 1 sampai 3%. Literature studi menunjukkan, untuk melakukan leaching dari terak timah secara efektif, formasi silica gel harus di cegah, oleh karenanya asam oksalat dipilih. Empat parameter leaching, konsentrasi asam oksalat, waktu, temperature, dan rasio, dipilih untuk mengekstrak tin (sebagai target) beserta titanium, tantalum, dan niobium. Eksperimen menunjukan, bahwa parameter leaching paling optimum berada di 24 jam waktu leaching, pada 50?C dan 10% rasio cairan dan solid.

Recovering tin from secondary resource proves to be an attractive alternative tin resource to help satisfy the ever-growing tin demands. Tin slag, considered as a secondary resource, still consist of tin in the form of oxides approximately 1 – 3%. Studies found that in order to leach tin slag effectively the formation of silica gel has to be prevented, hence oxalic acid was chosen as the leaching reagent for the study. Four leaching parameters, oxalic acid concentration, leaching time, leaching temperature and solid liquid ratio, were tested through the experiment to extract tin as the primary metal, along with titanium, tantalum and niobium. The experiment concluded that the optimum leaching time is at 24 hours with a temperature of 50?C at 10% solid/liquid ratio."

ABSTRACTArtisanal mining activities called by the Islands community with Unconventional Mine (TI), the more bloom almost cover all aspects of natural ecosystems to both land and sea which are not authorized in the process of mining activities. With the rise of mining activities, the IT dikabupaten South Bangka Regency Government of South Bangka Integrated Team illegal formed in an effort to curb the problem prevention and cessation of all forms of mining without permission. Integrated Team illegal formation is based on Decree of the Regent South Bangka No.188.45 / 67A / SAT POL PP / 2014 on the Establishment of an Integrated Response Team Mining without a license which refers to Bylaw No. 4 of 2011 on Mineral.This research focus is on the implementation of the policy. This study uses a qualitative method. The results showed that the implementation of policies to deal with unconventional tin mine (TI) experienced a variety of problems such as limitations of standard linkage and objectives, resources, communication between the organization and implementation activities, the implementing body characteristics, social, economic and political as well as the disposition executive influence policy implementation. The lack of clarity in the implementation of standards and goals, still a lack of resources support good policies that lack of human resources, financial resources, resources, facilities and information resources, as well as aspects of outside organizations such as social conditions, economic provide obstacles in the implementation process of policy implementation and the attainment of policy implementation"

"Pelebur bijih timah (smelter) merupakan bagian tidak terpisahkan dari pengusahaan pertambangan timah dalam memproduksi logam timah. Permasalahan utama adalah bahwa pelebur timah PT Koba Tin mempunyai kemampuan memproduksi logam timah sebanyak 12.000 ton per tahun dan hanya mampu mengolah bijih timah kadar tinggi. Untuk itu perlu dilakukan suatu analisis kelayakan dalam rangka rencana investasi penambahan alat pelebur bijih timah yang mampu mengolah bijih timah kadar rendah serta dapat memproduksi sebanyak 25.000 ton pertahun. Melalui penelitian dan analisis yang ditinjau dari beberapa aspek tentang analisis kelayakan tersebut rencana investasi penambahan alat pelebur bijih timah layak dilakukan apabila dilihat dari nilai laju pengembalian internal (IRR) yang jauh di atas tingkat pengembalian minimum yang menarik (MARK) serta nilai sekarang bersih sebesar US$ 20.362.429 dan periode pengembalian investasi selama 4 tahun 2 bulan. Analisa kepekaan memperlihatkan bahwa harga logam timah sangat berpengaruh terhadap kelayakan penambahan alat pelebur bijih timah, dengan menurunkan harga timah 2,5% atau sebesar US$ 4.290, IRR turun menjadi 5,5%, nilai sekarang sebesar US$ 96.707 dengan periode pengembalian 5 tahun 9 bulan. Dari hasil analisis keseluruhan bahwa rencana investasi penambahan alat pelebur bijih timah ini layak dikerjakan apabila harga timah tidak lebih rendah dari US$ 4.290, volume penjualan dan produksi harus lebih tinggi dari titik pulang pokok.

A tin ore smelter can not be separated from tin ore exploitation and tin metal production. Mean problem of PT Koba Tin smelter is its ability to produce 12.000 tons tin metal of highgrade tin ore per year. An analysis has to be done in order to plan an investment of tin ore smelter capable to process 25.000 ton of lowgrade tin ore per year.

Through feasibility analysis and study of some aspects an added smelter investment plan was recommended seen from its internal Rate of Return (1RR) which is far above Minimum Attractive Rate of Return (MARR) and also having a Net Present Value (NPV) equal to US$ 20.362.429 and an investment period returning of 4 years 2 months.

Sensitivity analysis show that tin metal price heavily influenced the addition feasibility of the tin ore smelter, by cutting 2,5% of tin price or equal to US$ 4.290, NPV is US$ 96.707 with a return period of 5 years 9 months. The overall analysis results shows the investment plan of the tin ore smelter is feasible if the tin price is not lower than US$ 4.290, sales and production must higher than the Break Event Point (BEP)."
