Judul: Analisis Sistem Bagi Hasil untuk Pembiayaan Negara Tanpa Pengalihan Dana dan Default Politik
Abstrak: State financing comes from two resources, domestic capital and foreign debt. Foreign debt is an investment from foreign investor. In fact, interest bearing debt is very high, and uses a system of high interest rates resulting in greater debt. This is due to the use of a conventional economic system. This paper gives an alternative solution for the state financing system using a profit-loss sharing system. The objective of this paper is to reconstruct the equation of profit-loss sharing model for external state financing taken from the paper of Bendjilali (1994) and ratio for optimal search result for financiers in cases of no diversion of funds and political default. The result of there construction process an optimal ratio obtained by maximizing the expected profit for foreign investor and the utility function for the state.

Judul: Analisis Hubungan Pinjaman Luar Negeri dan Kebijakan Fiskal di Indonesia
Abstrak: Indonesia is one of many developing countries that use foreign debt in its development. Foreign debt is one of aspects in fiscal policy. Accumulation of foreign debt every year has a relation with fiscal policy instruments such as government expenditure and tax revenue. Foreign debt also affected by economic growth and international interest rate. This research will discuss the analysis of the relation of foreign debt and fiscal policy in Indonesia. Analysis tools that used in this research are Granger causality method, Vector Auto Regression (VAR), Vector Error Correction Model (VECM), Impulse Response Function (IRF), and Forecast Error Variance Decomposition (FEVD). VECM estimation model result shows that in the short term equation, foreign debt is positively and significantly affecting the debt itself, while in the long term equation, all variables significantly affecting foreign debt which are Gross Domestic Product, government expenditure, tax revenue, and international interest rate. Gross Domestic Product positively affecting foreign debt. Government expenditure, tax revenue, and international interest rate is negatively affecting foreign debt. Result of IRF shows the same result with VECM estimation model for the effect of shocks from Gross Domestic Product, tax revenue, and international interest rate toward foreign debt. However, result of IRF for government expenditure shocks shows positively affecting foreign debt. Foreign debt shocks is affected by the debt itself that contribute with higher proportion in short term. While for long term, foreign debt is affected by the debt itself and other macroeconomic variables such as Gross Domestic Product, government expenditure, tax revenue, and international interest rate, but the effect of Gross Domestic Product toward foreign debt is higher than other variables.

Judul: Insecticidal Activity of Essential Oils Leaves of Cinnamomum spp. (Lauraceae) against Crocidolomia pavonana and Their Phytotoxicity on Broccoli Seedlings
Abstrak: Essential oils from leaves of 13 species of Cinnamomum were tested for their insecticidal activity on the cabbage head caterpillar Crocidolomia pavonana with leaf immerse method. The results showed that the treatment with 1% (w/v) essential oils leaves of C. celebicum, C. multiflorum, C. sintoc, and C. verum caused 21.45, 93.65, 60.30, and 76.10% mortality, respectively. Based on the results of phytotoxicity and insecticidal activity tests, C. multiflorum oil was further tested at 6 concentration levels. In all treatments, larval mortality has occurred at 24 hours after treatment (HAT) and increased at 48 HAT. LC50 of C. multiflorum oil at 24 and 48 HAT was 0.504 and 0.396%, respectively. The treatment with C. multiflorum oil at ≤0.31% did not inhibit the development of C. pavonana larvae. Determination of the chemical constituents of Cinnamomum oils were carried out by gas chromatography-mass spectrometry (GCMS). Totally, 345 compounds were identified. Methyleugenol constituted the main component (49.4%) of leaf essential oil of C. multiflorum and was assumed to be responsible for the insecticidal activity of the oil against C. pavonana larvae. LC50 of pure methyleugenol obtained at 0.365% (48 HAT) and 0.363% (72 HAT). The results showed that C. multiflorum was more effective with LC50 value equivalent to methyleugenol content of 0.32% (24 HAT) and 0.24% (48 HAT).
