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.

Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palm, primarily the African oil palm Elaeis guineensis. Oil palm is one of agriculture comodity that can increase farmers income, provide raw material on manufacture industry which can create added value. The expansion of oil palm farming in Indonesia has shifted the use of mineral land to suboptimal land which is currently available in many place in Indonesia. Generally the aim of this research is to anylize the competitiveness sensitivity of oil palm farming. Specifically this research wants to anylize the sensitivity on input-output changing, and to anylize the impact of government policy on input-output when facing fluctuation price. In order to reach the goal of this research we used Policy Anlayisis Matrix (PAM). The result of this research shows that partially the declining of price, declining of output volume and increasing input price PCR value and DRCR < 1, which means that the oil palm farming on suboptimal land has competitivenes, and the absence of government policy on determaining input price nor output price on oil palm farming in at suboptimal land. While simultanously shows that the fluctuation of input and output price causes value of PCR dan DRCR > 1 with PCR value 1,12 and DRCR value 1,04, means that oil palm farming on suboptimal land at Musi Rawas Regency not feasible and has no competitiveness. It means that government policy needed to protect input price in oil palm farming on suboptimal land. Therefore government support and guidence in oil palm farming technology on suboptimal land also needed to increase the production of oil palm farming on suboptimal land.

Perkebunan Karet rakyat di Kecamatan Tapung Hulu pada umum belum mencapai tingkat produktivtas yang tinggi. Penelitian ini bertujuan untuk menganalisis faktor dominan yang mempengaruhi produksi karet, tingkat efisiensi produksi dari aspek efisiensi teknis, alokatif dan ekonomi dan produksi optimum usahatani karet. Penelitian ini dilakukan dengan menggunakan metode survei yang berlokasi di Kecamatan Tapung Hulu Kabupaten Kampar. Data yang digunakan adalah data primer yang diperoleh dengan menggunakan metode wawancara. Sampel diambil dengan metode simple random sampling dengan 45 petani karet. Analisis data menggunakan statistik infrensia dengan regresi linear berganda dan metode Data Enveloment Analysis (DEA). Hasil Penelitian menunjukkan bahwa faktor dominan yang mempengaruhi produksi karet adalah tenaga kerja, pupuk TSP dan herbisida. Ketiga faktor produksi tersebut signifikan dan bepengaruh positif terhadap produksi karet dengan elastisitas produksi inlastis. Hasil analisis DEA menunjukkan bahwa pada umumnya petani karet inefisiensi secara teknis, alokatif dan ekonomi. Banyak petani yang inefisiensi secara teknis dan alokatif serta ekonomi disebabkan petani belum menggunakan faktor produksi yang efisien. Faktor produksi yang digunakan petani lebih rendah dari yang direkomendasikan. Dengan demikian perlu penyuluhan kepada petani karet tentang penggunaan input yang efisien.

HTI development involves many parties and stakeholders, one of which is the community living around the industrial forest area, whose existence cannot be separated from the forest. The location of the service in Bengkalis Regency is focused on Bukit Batu District. Data and information were collected through interviews and Focused Group Discussions. The results of the identification of social impacts found negative impacts from the existence of HTI companies on the people in the survey villages, namely land ownership conflicts, labour recruitment, and road dust that interfered with the residents' health. While the positive impact felt by the community is CSR assistance such as commemorating the anniversary of Indonesia's independence, sports competitions, and others. Additionally, the forest management efforts that must be carried out are socialization of a persuasive approach to the community to resolve conflicts between HTI companies and community lands, provide the widest possible opportunity for local workers in companies according to their level of education and experience, and prevent road dust so that it no longer disturbs the health of the population.
