Judul: Fertilizer demand for rice cultivation in Java and Bali
Abstrak: This study analyses the factors affecting fertilizer demand for rice cultivation in Java and Bali. Fertilizer demand, as a function of the fertilizer-rice price ratio and differences in the level of fertilizer used, is estimated for each Provinces by using covariance analysis. In an alternative formulation, fertilizer demand function captured the different production responses as well as different price responses between provinces. The alternative demand function needs estimates of production elasticity of fertilizer belonging to each province. These production elasticities are obtained by employing covariance analysis in the Cobb-Douglas pro- duction function. From the production function analysis, the study has found that production elasticities are different between provinces. From an alternative demand function analysis the study has found a) Demand is more price elastic in the equation which only captures the different in price response than in the equation which captures both the different in price response and production response. b) the production elasticity has a greater effect on quantity of fertilizer demanded than the fertilizer price relative to rice. By employing covariance analysis in the production function and the demand function, a weakness is introduced. We cannot employ covariance analysis as slope shifters to distinguish interprovince difference in the production elasticity of demand in log-log functions. If this is done as a few past studies, then both the intercept term and the slope term are affected by a change in the measurement unit, even though log-log functions are used, with supposedly "measurement-unit-free" elasticity estimates. This is contradictive to our expectation.

Judul: Analisis Efektivitas Subsidi Pupuk dan Faktor-Faktor yang Mempengaruhi Produksi Padi (Studi Kasus Desa Hambaro, Kecamatan Nanggung, Kabupaten Bogor)
Abstrak: Agriculture is an important aspect in favor fora country survival. Indonesia, as an agricultural country places the agriculture as the dominant sector in the national economy. Therefore, there are various government policies that support the production of the agricultural sector. One of those policies is the fertilizer subsidy policy. The fertilizer subsidy policy is fiscal policy which aims to support the agricultural sector by providing the input in subsidies setting HET fertilizer form. This policy is implemented based on six indicators of the success; the right type, quantity, price, quality, place, and time. The purpose of this research is to analyse the effectiveness of the fertilizer subsidy policy and to determine the factors that affect the production of rice. Observations and interviews in the rice-producing regions had done in the Hambaro-Bogor village which were taken through purposive sampling method. Analytical method used is descriptive quantitative and qualitative methods, and multiple linear regression methods. The results show that the effectiveness of the fertilizer subsidy policy isbased on four indicators, those are names, right place, right price, and punctuality. However, the right amount of fertilizer subsidy policy approves thatit is still not categorized as effective yet. The ineffectiveness of the subsidy of fertilizer effect on rice production turns out as shown on the results of the regression. Variable rates of fertilizer urea have a negative and significant effect on the demand for urea fertilizer. It means that if the urea fertilizer prices increased,the demand for urea fertilizer would be lower. In addition, variable price of rice and land area have a positive and significant impact on the demand for urea fertilizer. Variable amount of price of urea, price of npk, labor, land area of seed and dummy has a positive and significant impact on the production of rice. In other words, the event of changes toward these factors will have an effect on the production of rice.

Abstrak: Haemoproteus columbae merupakan paras it yang menyerang sel-sel darah merah burung rnerpati. Siklus hidupnya kompleks dan dapat dibagi menjadi dua yaitu siklus hidup asexual terjadi delam tubuh burung merpati dan siklus hidup sexual terjadi dalam tubuh lalat dari famili Hippoboscidae sebagai vektor. Stadium yang nampak dalam peredaran darah perifer hanyalah garoetosit yang dapat dibedakan menjadi dua yaitu gametosit jantan (mikrogametosit) dan gametosit betina (makrogametosit).
