Due to its characteristics siomay sauce can be incorporated with RPO (RPO) for vitamin A fortification. The objective of the study were determining the effect of RPO addition to the characteristic of siomay sauce, and determining the preference of siomay sauce added with various amount of RPO. A four levels addition of RPO (0.0 g, 1.5 g, 3.0 g and 4.5 g) were added to siumay sauce. The physical characteristics (viscosity, emulsion stability), sensory evaluation (hedonic test and duo-trio test) of the sauce, and the retinol equivalent of fortified siomay sauce were evaluated. The result showed that viscosity of siomay sauce increased with increasing addition of RPO into the sauce. The hedonic test revealed that the overall preference of original siomay sauce added with 4.5 g of RPO was not significantly diferent from the controll. In addition, siomay sauce enriched with 4,5 g RPO could increase 325.22 ?g retinol equivalents (RE) or equal to 38.26 % of the RDA of vitamin A for lactating woman. The finding suggest that siomay sauce fortified with RPO could be used for combating Vitamin A deviciency.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125286582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Survey of 84 siamese orange farmers selected using simple random sampling is conducted to get orange farming data. The comparative advantage level is measured using Policy Analysis Matrix (PAM) approach. The results show that siamaese orange farming has a high comparative advantage. This showed by a value of social profitability was more than zero and domestic resource cost ratio was less than one.

The purpose of this study consisted of two things; the first is to identify the factors that influence the demand for Indonesia's CPO exports to Pakistan. The second is to analyze the relationship between the production of CPO, the international and domestic price of CPO, and the exchange rate of Rupiah toward the volume of Indonesian CPO exports to Pakistan both in the long and in the short term of time. This study used time series data (1973-2016). The analytical method used in this study was Error correction model (ECM) to examine the correlation of variables: Indonesian CPO production, the international and domestic price of CPO, the international price of coconut oil, the international price of soybean oil, Pakistan’s GDP per capita, the inflation in Pakistan, and the exchange rate of Rupiah toward the export variable of Indonesian CPO to Pakistan by using software E-Views 6.0. Based on the results of this study, it is concluded that the factor affecting the short-term demand of Indonesia's CPO exports to Pakistan is the international price of CPO which has a significant negative correlation, while the factor affecting long-term demand is the exchange rate of Rupiah toward the US$ which has a significant positive correlation. There is no correlation between both Indonesian CPO production and domestic price of CPO toward Indonesia's CPO exports to Pakistan both in the short and in the long term.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125318925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These patterns include area as Wheat-Maize (WMCP) and Wheat-Fodder (WFCP) in Kahuta (high rainfall climatic area), Wheat-Millet-Fallow (WMFCP) and Wheat- Millet-Lentil (WMLCP) in Khairimurat (medium rainfall climatic area) and Wheat-Fallow (WFCP) and Fallow-Groundnut (FGCP) in Pindi Gheb (low rainfall climatic area). In areas that have more crop water requirements the yield of these crops has been affected when the drought prevails. Our results evidenced that more average soil water content (ASWC) was available in high to medium height terraces in WMCP and low to medium in WFCP of Kahuta area. ASWC remained more in high to medium height terraces under all cropping pattern of Khairimurat during September. ASWC remained more in low to medium height terraces under all cropping pattern of Pindi Gheb during September and December. Equidistantly, soil water release curve also indicated that medium rainfall sites had more plant water availability as compared to high and low rainfall sites. Yield relationship to plant water availability revealed significance for intrusion of modified cropping patterns rather than existing cropping patterns on sustained basis. Finally, our study suggests that cropping patterns of high and low rainfall areas should adjusted by growing low water requirement crops in summer seasons to cope the drought period for the sustainability of agriculture under rainfed climatic conditions.
