Indonesian Government have a target to improve productive land for agriculture and to increase corn and soybean production this year. This program should be supported by all stakeholder. The existing paddy field and dry land is constrained by the massive conversion of agricultural land especially in Java island which reaches 110 thousand hectare per year. Besides that the availability of labor decrease constantly, it give impact in decreasing the agricultural production. These condition make the government target achievement will be difficult. The objective of this research is to develop machinery for land preparation that is combined with corn seeder. This machine is proposed to be used for land preparation and corn seedling in dry land. With this machine the land preparation and corn seedling is done at one time so it will shorten the working time and increase the intensity of planting in one year. The modification is made in some components of crawler tractor so it can be mounted with grain seeder. The indicators of success are 1) the machine can work properly, 2) increased work capacity, 3) decrease of labor cost. The result of this research is expected to help farmer to gain more agricultural yield and help Indonesian government to achieve national self-sufficiency of corn. The result of field test are : field work Capacity is 4.36 hours / ha; fuel requirements: 26.29 l / ha; Wheel Slip: 0.23%; Field work efficiency: 73.96%; Depth of soil: 14.2 cm; Work width: 167.5 cm; distance between rows of plants: 70 cm (adjustable); distance in line 25-30 cm.

The Zn1-xMnxO ($0.00{\leq}x{\leq}0.06$) samples have been synthesized in the form of powder by the coprecipitation method at low temperature using $Zn(CH_3COO)_2$. $2H_2O$ and $Mn(CH_3COO)_2$. $4H_2O$ powders, as well as HCl and $NH_4OH$ solutions as starting materials. Characterization was conducted using XRD, TEM, XRF, FTIR and VSM. The result shows that the $Zn_{(1-x)}Mn_xO$ ($0.00{\leq}x{\leq}0.06$) nanoparticles have the wurtzite phase with a hexagonal structure and particle sizes ranging from 17.48 to 118.83 nm. In a qualitative analysis of XRF, the peaks that confirm the existence of the manganese element in Mn-doped ZnO samples were observed. Meanwhile, FTIR test result shows that there are peaks at around $500cm^{-1}$ and $400cm^{-1}$ in the FTIR spectra for Mn doped ZnO samples which clearly reveal the existence of the (Zn, Mn)-O strain mode. The (Zn, Mn)-O absorption peak positions have shifted to a lower wave number with increasing Mn doping content. The peak intensity is also lower if compared to that of the ZnO sample without doping. From the VSM test, it is shown that $Zn_{(1-x)}Mn_xO$ ($0.00{\leq}x{\leq}0.06$) nanoparticles are all paramagnetic having monotonically increased susceptibility as increasing Mn content.

The impact of career development on employee performance: an empirical study of the public sector in Indonesia

Saud Napitupulu,Tulus Haryono,Asri Laksmi Riani,Hunik Sri Runing Sawitri,Mugi Harsono 한국행정학회 2017 International Review of Public Administration Vol.22 No.3

This article examines the infl uence of career development on employee performance in public sector, mediated by perceived organizational support, work motivation, and affective commitment. By analyzing the perceptions of 250 civil servants in 15 regional branches of Ministry of Finance of Indonesia, and using structural equation analysis with SmartPLS 2.0 program, the findings reveal that career development has positive direct influence on perceived organizational support, motivation, and affective commitment. However, career development has no direct influence on performance. The indirect examination shows that mediating variables are perceived to have significant influence in strengthening that relationship. These findings theoretically imply that career development may be dependent on the extent to which organization is capable of providing perceived organizational support and motivation in promoting affective commitment and performance. Practically, these findings reveal the importance of both Indonesian’s central and local government to implement performance-based rewards.
