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: Sustainable Regional Development Model through Structural Transformation of the Mining Based To Local Renewable Resource Based Economy (Case Study of Copper and Gold Mining of Newmont Nusa Tenggara, Co., at Batu Hijau in West Sumbawa),
Abstrak: Struktur perekonomian Kabupaten Sumbawa Barat NTB sejak 2000-2006 sangat dominan tergantung pada satu sektor yakni pertambangan tembaga dan emas proyek Batu Hijau PT. Newmont Nusa Tenggara (PTNNT) sebesar 94 % dalam produk domestik regional bruto (PDRB). Sektor pertambangan di Sumbawa Barat termasuk salah satu tambang skala besar di Indonesia sehingga dominasinya tidak hanya terhadap PDRB Kabupaten tersebut namun juga berdampak secara regional bagi Provinsi NTB. Performa proyek Batu Hijau PTNNT saat ini adalah 1) komposisi kepemilikan saham perusahaan tersebut 80% dikuasai perusahan asing (Newmont Indonesia Ltd dan Nusa Tenggara Mining Corp) dan 20% dikuasai oleh perusahan swasta nasional (PT. Fukuafu Indah). Didalam Kontrak Karya proyek Batu Hijau PTNNT terdapat pasal yang mewajibkan perusahaan tersebut melakukan divestasi saham hingga 51% (tahun 2010) untuk promosi kepentingan nasional (PTNNT, 2000). Berdasarkan keputusan arbitrase internasional, divestasi saham 2006 dan 2007 sebesar 10% menjadi milik pemerintah Propinsi NTB, Kabupaten Sumbawa Barat dan Kabupaten Sumbawa bekerjasama dengan PT. Multi Capital dengan komposisi 75% milik PT. Multi Capital dan 25% milik 3 Pemda tersebut, 2) peluang usaha selama masa operasi menurut kinerja departemen kontrak (2005) dimanfaatkan oleh nasional (92%), Propinsi Nusa Tenggara Barat (5%) dan Sumbawa Barat (3%) (PTNNT, 2005), 3) kontribusi proyek tersebut terhadap kapasitas fiskal (APBD) Kabupaten Sumbawa Barat tahun 2005 sebesar Rp. 80,98 Milyar dengan perincian dana bagi hasil sumberdaya alam Rp. 56,17 Milyar, dana bagi hasil pajak Rp. 24,39 Milyar, pendapatan asli daerah Rp. 0,31 Milyar, dana alokasi umum Rp, 0,09 Milyar dan dana alokasi khusus Rp. 0,01 (LPEM UI, 2006), 4) sedangkan komposisi tenaga kerja adalah Sumbawa Barat (33%) dan non Sumbawa Barat (67%).

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
