Rubber is a plantation crop which is mostly a source of community income in Kampar District. As a source of household income, rubber farming is managed by households independently. This study generally aims to design models and government policy strategies in the development of smallholder rubber plantations on land typology mineral land conditions on the economic decision making of rubber farmer households. Specifically, this study was conducted with the aim of analyzing the characteristics of independent smallholders and internal and external dominant factors that influence the allocation of working time, income and household expenses of rubber farmers. This research was conducted using a survey method located in Kampar District. The data used in this study consisted of primary data obtained using the interview method. Samples were taken by simple random sampling method with 60 rubber farmers. Descriptive analysis and Economic Decision Model of Rubber Farmer Households using the simultaneous equation model approach with the Two Stages Least Square (2SLS) analysis method were performed to answer the research objectives. The results showed that only internal factors of farm households are responsive to household economic decisions. There are no external factors included in the model that are responsive to the economic decisions of rubber farming households in Kuantan Singingi Regency regarding the aspects of production, working time allocation, income and expenditure of rubber farming households. From the aspect of production, no responsive internal or external factors were found, but the biggest effect was the number of productive rubber stems. From the aspect of work time allocation, internal factors that are responsive to influence are the total outpouring of farmer work, outpouring of farm family work in businesses and the workforce of farmer households. Furthermore, from the aspect of farmer's household income the responsive internal factors that influence it are the farmer's household income in the business. then what influences household expenditure is outflow of work in business, farmer education, wife education and total rubber farmer income. The policy implications of increasing rubber prices and outpouring of family work in the business have the most positive impact. While the increase in wages for workers outside the family has a negative impact on the household economy.

This research generally aims to analyze the behavior of food consumption source of carbohydrate, specifically, this study aims to analyze the dominant factor and analyze the response of food consumption expenditure dominant source of carbohydrate for factors that influence it. To answer this research purpose built models Almost Ideal Demand System (AIDS) were analyzed by methods Seemingly Unreleated Regression (SUR).Food commodities sources of carbohydrates are included in the model to include five commodities (commodity groups), include: rice, yam, noodles, cassava and potatoes. The results showed that the higher the income level, the proportion of food expenditure of commodities as rice, yam, noodles, cassava, and potatoes tend to increase. Meanwhile, the higher the mother's education the more domestic rice consumption, while consumption of yam noodles, cassava and potatoes tend to decline. The analysis showed that the price elasticity of its own for the entire commodity observed negative sign except cassava and yams and potatoes only the value of elasticity is greater than one. This indicates that the commodity consumption expenditures yams and potatoes are responsive to changes in its price. Similarly, the cross-price elasticities show the value of elasticity (in absolute value) with cassava yams and potatoes is greater than one, means commodity consumption expenditures yams are responsive to changes in prices of other commodities. Meanwhile, the income elasticity shows two commodities that have an income elasticity greater than one, which is the income elasticity for commodities noodles, and cassava. From these findings it can be stated that the policies related to revenue-raising efforts should be made to boost household consumption, especially consumption of palm oil farmers noodles and cassava, while the price control policy needs to be done to increase the consumption of yams.
