Methods of data analysis that is used to find out the factors that affect the production of sugar cane and the level of technical efficiency of sugar cane farming is a stochastic production frontier. In order to find the factors that affect technical inefficiency of sugar cane efficiency, Tobit analysis is applied. The results show that the influential factors towards the production of sugar cane in the dry land i.e. number of seedlings and the number of labor, while sugar cane production in the irrigated land are the amount of labor, Urea fertilizer, Ponska fertilizer and herbicides. The average technical efficiency of sugar cane farming achieved in the dry land is 0.887 and the average technical efficiency of irrigated land is 0.928. Factors that influence technical inefficiency of sugar cane farming in the dry land are rejuvenation of sugar cane (keprasan), frequency of counseling, and seeds.

There are farmers that are able to manage the risk; however, most of them fail to adapt the risk and uncertainty. If catastropihic losses happen then the farmers will suffer and come to the poverty. Therefore, government of Indonesia attempts to conduct agricultural insurance policy to prevent that case happening specially for small-scale farming. This study contributes in understanding what factors will endorse the acceptance of agricultural insurance for small-scale farming. The data analysis employed is binomial logistic regression in finding factors that negatively or positively affect the agricultural insurance program. The data was obtained through survey conducted in January to Mei 2017. The location of this study is Malang Regency, East-Java Province, Indonesia. The results found that there was 50 percent of the farmers accepting the agricultural insurance program and the other half of farmers unwilling to support the program. Regarding factors which affect negatively to the willingness to accept agricultural insurance are age, profit, and the number sources of income. Then, the factors which affects positively to the agricultural insurance are farming size, the experience of buying insurance, and also the intencity of farmers in attending farmers’ group meeting.","PeriodicalId":130060,"journal":{"name":"Agricultural Socio-Economics Journal","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128951726","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}

Indonesia needs to improve the competitiveness performance. This study investigates the growth in exports of Indonesian Cassava in the World Market. The Constant Market Share (CMS) was used to measure the growth in exports of Indonesian Cassava. Based on result of Constant Market Share (CMS), Indonesia, Thailand, and Vietnam maintained their share in the world market during the Global Economic Crisis, because the growth rates of dried cassava import relative quickly during the crisis. The crisis make the import of other commodities are decreased during the crisis. But, it did not happen for dried cassava.

These small islands have limited capacity of land resource along with low efficiency of food distribution so that it influences sufficiency level of affordable food availability. Therefore, the aims of this research are: (1) to analyze regional food balance to fulfil food and nutrition needs; (2) to analyze the direction of food production development with small island basis; and (3) to analyze the interaction pattern of food distribution among small islands to ensure sufficiency food availability. This research was conducted in March-December 2016 in South Halmahera Regency. This research design is explorative using primary and secondary data. Primary data was collected by observation results, interview, and Focused Group Discussion (FGD). The result research shows that land optimization for the development of Wetland Food Crops (TPLB), Dry land Food Crops (TPLK), and Annual Food crops (TPT) are able to fulfil South Halmahera people’s food needs and its land availability surplus is 5.159,2; 34.834,9 and  21.971,0 ha.

These functions and benefits are very important but are not appreciated by society. Giving economic values to paddy fields based on these two faculties will inform the society how valuable paddy fields are as natural resources. The economic valuation method used in this reserch is the Replacement Cost Method (RCM) with mathematical formula as follows NELSsFPUH = (U N x P n + U P x P p + U K x P k + U BO x P BO ) x A for economic value of paddy field as provider of nutrients contents (N, P, K) and organic matters; and NELSPK = (WK/KK) x PK x A for economic value of paddy field as compost container. The research was taken place in 6 sub-subdistricts in Lowokwaru Subdistrict with 205 hectares of paddy fields.  The economic value of paddy field is about Rp 133,31 billions for economic value of paddy field as provider of nutrients contents (N, P, K) and organic matters; and Rp 7,76 billions for economic value of paddy field as compost container.   For both faculties the average economic value Rp 688,18 million per hectare. Paddy fields in Lowokwaru Subdistricts are very feasible to be protected from conversion due to its satisfactory soil fertility and its potential to be increased, thus it is able to maintain land productivity. Therefore, it is very reasonable to call pady fields as productive open green space in which economic and social activities can be developed","PeriodicalId":130060,"journal":{"name":"Agricultural Socio-Economics Journal","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128638394","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}

There are many sugarcane production in some areas still not been used by the sugar factorys. Capacity of sugar factorys that are still on a small scale led to these production of sugarcane being not fully used. One effort to utilize the production of sugar cane is to built a new sugar factory. This study aimed to analyze the deciding factorsof the sugar factory industry site selection and determine potential locations in Blitar.

Coefficient of variation (CV) of Chili price is 0.32 and the CV of chili production is 0.05. The risk of price is higher than production risk level due to the fact that price is more volatile and more difficult to control by farmers . Additionally, production risk is still manageable and can be controlled by farmers through the implementation of off-season cultivation technology combining by the experience of farmers in the production.
