Abstrak: Regional leakage is an important issue that causes the effect of economic growth on the distribution of incomes in a region to be small. The greater the leakage that occurs, the greater the potential income multiplier of an area to be lost. To create quality of economic growth (better distribution of income), it is necessary to reduce the efforts of regional leakage. The magnitude of the mining sector's contribution to economic growth (GDP), otherwise paradoxical impact on economic performance and social performance. The cause was a leak in the regional mining activities in the district of Musi Rawas. Regional leakage in the mining sector due to the type of activity expenditure / receipts which do not increase additional revenue for the district of Musi Rawas. Regional leakage flow is the condition of the value added to other areas because of the potential added value that can not be used optimally, thus causing small multiplier. Issues caused by the leakage area mining sector is an important thing that concerns this study. This thesis aims to analyze the regional leakage in the distribution of mining revenue in Musi Rawas. Specifically this study aims to analyze the role of the mining sector in the economic performance of the region and analyze sector linkages, multipliers, dostribusi income, and the potential indications and kebocoranregional on pertmbangan sector activity. To answer the problems and research objectives using a secondary data analysis of the Social Accounting Matrix (SAM) Musi Rawas regency in 2010. The outcome this study results show the contribution of the mining sector, total exports and GDP is quite significant. In general, the amount contributed to the acceptance of NTB / GDP tends to be greatest acceptance factor than labor capital. Sisitenaga be working most of the revenue receipt employers than workers. This condition has been proved indication of leakage area. Between the amount of fee (BA) relatively little has been linked with other domestic sectors, due largely a commodity imports. The amount of imported inputs expenditure ratio is indicative of the occurrence of leakage areas (regional leakage). Policy simulation shows the potential increase in output increases total domestic revenues, and NTB/GDP. But that tends to increase in capital compared to labor with considerable ratio is an indication of the region and the potential for leaks. The highest increase in income received by non-agricultural employment and the lowest received by the agricultural workforce. The growth labor factor income is received by the highest effort and the lowest production are agricultural laborers. Ratio of income between workers with relatively high capital. In terms of institutional income (households, firms, and government), an increase in household income in the institutions most likely to be enjoyed by nonagricultural households compared to farm households. Ratio of income between households with relatively very large employers an indication of leakage area. While the mining sector linkages with other sectors is not so significant. The increase in revenue to other production sectors tend to have a big impact to the food and beverage sector of the oil and gas sector, and to the trade sector

Abstrak: This study is conducted to examine and determine the role and contribution of plantation sector in Musi Rawas development to analyze the level of leakage in the regional economy and the role of marketing institutions in plantation sector. In its analysis this study use Social Accounting Matrix (SAM) model. SAM analysis resulted that the average of household income in plantation sector estimated 6,72 million rupiahs per year, and plantation sector contribute greatly to regional economy in Musi Rawas regency when compare with other agricultural sector. Beside that, plantation sector has big of multiplier effect to employment, household income, GDP and economic output. The plantation sector has a Value Added Multiplier (VAM) of 1,25, and based on the estimated impact of simulated output increase on the plantation sector it was seen that the average output of the plantation sector was 1,78, which means that when injected at 1 billion rupiahs, it would create an output of 1,78 billion rupiahs, with the highest output for the commodity of community rubber. In addition, the average inequality value in the household income in the plantation sector was 3.96, which calculated from income revenue by non farm group as recipients of the highest revenue compare with earnings of agricultural laborers as low income earners, with the palm oil commodity having the smallest value of household income inequality. From the Regional GDP of 7,68 trillion rupiahs there was a regional leakage of 357,36 billion rupiahs, or approximately 4.65% of the Regional GDP derived from the labor force factor of 4,14 billion rupiahs and capital factor of 353,22 billion rupiahs. This is because of the presence of capital in Musi Rawas from outside of the region. As a result, the remuneration obtained by the production factor also flows back out of the region. To overcome the regional leakage will require a policy reform such as local regulations regarding the opening of the processing plant for value added crops, which flows out can be enjoyed by the people, beside that Corporate Social Responsibility (CSR) is used to education and training to increase the farmer skill and improving the quality of human resources. The institutional role of farmers is still very weak; it is mainly due to a) lack of guidance, b) ineffective application of government regulations that favor farmers, c) lack of social capital or farmer’s poor institutional aspects particularly in the form of networking, regulations and transparency. On the other hand there is a low access of farmers to markets because the market information has not been exploited optimally, the role of middlemen is still high in the marketing of rubber, and there is no auction market and poor infrastructure to support marketing support. Therefore need to increase the farmer ability such as work ethics, kowledge and skill to process rubber and palm oil

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
