Judul: Analisis dampak interaksi pertambangan dan perikanan terhadap kesejahteraan masyarakat nelayan di Kabupaten Sumbawa Barat
Abstrak: District of Sumbawa Barat is administratively separated from Sumbawa district, NTB Province. The existence of mining company, PT. Newmont Nusa Tenggara (PT.NNT), is expected can increase the welfare especially for the fisherman society and Sumbawa Barat societies in general. The objectives of this research were analyzing the impact of fishery and mining interaction to fisherman society welfare and formulate the strategy for increasing fisherman society welfare. Data analysis was conducted descriptively, bioeconomic analysis, consumer and producer surplus analysis, and t-test statistic. Results of the research show that the existence of PT. NNT doesn’t give welfare change for local fisherman society, eventhough for the villages which close with the area of mining activities there was the increasing of income amount of IDR 282.523.496,-. The increasing of income is caused by the increasing of fisheries commodity price which caused by the decreasing number of fisherman catching. Whereas the villages which far from mining activities face the decreasing of income amount of IDR 1.289.351.440,- after the existence of PT. NNT. The existence of PT. NNT cause the increasing of catching fishery commodity price amounting of IDR 15,03,- for the villages which close with area of mining activities and amounting of IDR 35,33,- for the villages which far from area of mining activities. This condition cause the decreasing of society’s purchasing power. Secondly, the fishery policy strategies for increasing the local fisherman welfare are a) developing catch fishery, b) developing quality of fishery production, c) developing hatchery, d) developing sea cultivation and e) developing fish pond cultivation.

Judul: Analisis dampak ekonomi dan sosial tambang emas dan tembaga bagi masyarakat komunal dan pembangunan wilayah Propinsi NTB (Studi kasus : Proyek Batu Hijau PT. Newmont Nusa Tenggara di Kabupaten Sumbawa)
Abstrak: Indonesia adalah salah satu negara di dunia yang memiliki kekayaan sumberdaya mineral yang cukup melimpah. Paradigma pemanfaatan dan pengelolaan sumberdaya mineral yang bercorak senttalistik, berpusat pada negara (state base resources management) menempatkan pemerintah pada posisi yang sangat power full untuk menggunakannya dengan dalih mengejar target pertumbuhan ekonomi (economic growth development), demi peningkatan pendapatan dan devisa negara (state revenue). Konsekuensi paradigma semacam itu, dalam tiga dekade terakhir ini, pertama, daerahdaerah yang kaya sumberdaya mineral justru menjadi daerah pengurasan (massive backwash effect) oleh pemerintah pusat, sehingga kekayaan sumberdaya mineral justru telah memiskinkan sebuah wilayah. Kedua, hampir semua lokasi industri pertambangan di dunia merupakan tempat tinggal masyarakat adat,kornunal/lokal, tidak terkecuali masyarakat lokal Sumbawa.

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
