Modernization in catch fisheries sector by mean machinary application for fishing could be devided into some phases. Every phases showed some production relation between the ship owners and their labours. In the Marxist tradition of thought, the study about these relationship could be gained by elaborate the mode of production. For more specific, this study were elaboratethe mode of production in every phases of modernization. Mode of production consisted force of production and relation of production. In this context, force of production was mean of production like ships, net and seine. While relation of production wasthe organization of fishermen, power and control by the owners to their labours. The study was conducted by using qualitative method so depth interviewed of some key informants had been main method in collecting datas. The results of the study indicated that fisheries modernization in research area held into four phases. We called them as period oflancang, trawl, bagan, and purseseine. Further more, the mode of production in every phases as follow namely, lancang was subsistence production, trawl was commercialist production, and bagan was commercialist production. While purseseine had has two mode of production, namely commercialist production for Bengkulu’s owner and capitalist production for Chinese’s owner.Keywords : mode of production, Pulau Baai, Lancang, Trawl, Bagan, and Purse Seine.

The need for beef in Indonesia tends to increase along with fluctuated beef prices. The existence of price fluctuations will be a risk for producers and consumers. Therefore, price information is necessary, especially the future beef price and price forecasting is the answer to the need. The purpose of this study is to analyze and identify the best forecasting models for domestic and international beef prices. The data used is monthly retail price data for domestic and international beef from 2013:1-2017:12. Four models used in this study, namely decomposition models, ARIMA, moving averages, and Single Exponential Smoothing are applied. The best forecasting method for forecasting domestic and international beef prices is the ARIMA model based on the lowest values of MAD, MAPE, and MSD.

Goat farming is the good source of income for people living in countryside, Nepal. This occupation supports socioeconomic living of many people in developing countries. Gastro-parasitic infections in goats can decrease the meat supply in a country where demand of goat meat is ever increasing. The objective of this study was to identify the gastrointestinal parasites in feces of goats and impact of seasonal changes on their prevalence. This is a cross-sectional study done on 212 goats from Kapilbastu, Nepal. For this study, feces of goats were collected during summer and winter and observed microscopically to find the causative organisms. The result showed the helminths from trematode (22.22%), cestode (12.5%) and nematode (65.27%) caused heavy gastrointestinal infection in 144 microscopically positive samples taken from Kapilbastu, Nepal. The major helminths were Toxocara (16.66%), Oesophagnum (8.32%), Strongyloides (6.25%) and Trichuris (4.86%) among nematodes, Fasciola (15.97%) caused highest infection among trematode and Taenia (9.72%) among cestode. The prevalence of these infections was significantly higher during summer than winter. The higher prevalence of these helminths is the indication of supply contaminated food and water. Moreover, unawareness and ignorance about such diseases can increase the infection rate. Proper management of goat farm together with good cattle rearing training can increase the productivity.

Siomay is a popular street foods in urban and rural areas of Indonesia. 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.
