Abstract

Omniwheels robot is a kind of mobile robot that can be moved to any direction, different cases than non-holonomic mobile robot. The advantage of omniwheels is shape of the wheel. Control method of this research is kinematic control. The derivation of such method is matrices velocities of omniwheels robot.Than, the control system was implemented to tracking trajectory problem. Still in the control system, it was choosing closed loop control for auto navigation problem. Finally, the robot also was used ultrasonic sensors for obstacle avoidance problem.

Abstract

Finding of previous studies shows that Sumatera Economic Corridor is categorized as the highest income inequality. The Indonesian goverment enacts MP3EI (Master Plan for the Acceleration and Expansion of Indonesia Economic Development) program to promote equitable development where each economic corridor owns strategic economic sector. The objective of this study is to analyze the contribution of agricultural sector on income inequality in Sumatera Economic Corridor (SEC) using a weighted coefficient of variation. We use secondary time series data of Gross Regional Domestic Product (GRDP), number of population, and per capita income of a time range between 2002 and 2013. Data analysis shows that agricultural sector has the least contribution on income inequality. Consequently, goverment policy should be focusing on the development of agricultural sector in Sumatera Economic Corridor

Abstract

The objectives of the study are (1) to analyze the household’s income structure of corn farmers based on variety types and land holdings and (2) to see the relation between income distribution and land holding and types of variety. Data analyzed in the study were collected from two main corn-producing districts during the planting seasons of 2007/2008. Results of the study show that share of income from farm business to the total households’ income is relatively high, i.e., shares of income from corn farming based on variety type varied from 44 to 87 percent in Sinar Tebudak and 49 to 87 percent in Pangmilang. Distribution of corn farming income for all types of variety is more balanced than that of total households’ income due to variation in non-farm income. The study also indicates that there is a positive correlation in all variety types between total households’ income and land holding. The use of superior variety could improve distribution of corn farming income and distribution of households’ income. Implications of the study are (1) enhancing non-farm employment in rural areas is essential to improve households’ income; (2) implementing land reform is one of the instruments to create a better distribution of land holding and income distribution in rural areas; and (3) improving supporting inputs and facilities like water irrigation, fertilizer, pesticide, credit and agricultural extension service for the corn farmers are essential in order to improve income distribution in the study area.Keywords: variety type, income distribution

Abstract

The southern part of the Special Province of Yogyakarta consists of a coastline spanning over 113 km, under the administrations of Bantul, Gunung Kidul and Kulon Progo regencies, that can become an asset and resource of an important economy. Cabe Merah (red chilli) is one of the commodities that show high numbers of productivity in Kulon Progo Regency. Activities of red chilli farming on the coastal land of this regency have been growing, especially since the establishment of commodity auction market to help farmers sell their harvests. The study was conducted to (1) find out the size of production in red chilli agribusiness on coastal land, (2) to analyze the risk levels of production faced by the farmers, and (3) how to mitigate the production risks on coastal red chilli farming. There were 40 participating farmers from Banaran Village, Galur Sub-district, Kulon Progo Regency. The location was intentionally chosen by using  multistage area sampling method. The data used were collected from the production and income of three growing seasons. Data analyses were performed using production risk and The House of Risk methods. Based on the variance coefficient, the production risks level was at 0,03 with the production lower limit of 9.596 Kg/Ha, which showed a low level of risk. The various risk mitigation strategies have been performed by the farmers to lessen the risks that can causes losses in the process of coastal red chilli productions.

Abstract

The Agricultural machinery rental services (UPJA) program has an important role on the application of agricultural mechanization and increasing farming income. This study aims: (1) to compare the farm costs between the farmers who apply  mechanization under UPJA program and those who do not (Non-UPJA), and (2) to know the effect of implementing agricultural mechanization and the other factors toward farm income in Prambanan Sub-District, Sleman District. The data collected consists of 25 farmers who apply agricultural mechanization under UPJA program, choosen by sensus and 25 farmers who do not apply (Non-UPJA), choosen by using proporsional random sampling. To determine the differences of farm costs, farming analysis and mean difference test using independent sample t-test was applied. To determine the effect of mechanization toward farm income, multiple liniear regression analysis was used. The result of mean difference test showed that there is no significant differences of farm costs between UPJA and Non-UPJA farmers. The result of multiple  liniear regression analysis showed that mechanization has significant effect to the farm income. Farm income of the farmers who apply mechanization under UPJA program is significantly higher than the farmers who do not. Other factors that have significant effect to farm income are land area, price of organic fertilizer and price of ZA fertilizer.
