Abstract

Purpose of this research is to known effect of work culture and work environment to motivation and organizational commitment, and effect of each variables to performance of Komisi Pemilihan Umum employees of Karanganyar Regency. The technique sampling used in this study is census method. The sample in this research is 32 respondents. The data collecting techniques is used observation and questionnaires. The data analysis technique is used research instrument test such as validity and reliability tests; linearity test; hypothesis test such as path analysis, t test, F test, determination coefficient; variable correlation. The test results shown that all instruments are valid and reliable. The result of this research shown that: Work culture and work environment has positive significant effect both to motivation and organizational commitment. Work environment, motivation and organizational commitment has positive significant effect to performance, but work culture have negative insignificant effect to performance. Work culture and work environment has positive significant effect to performance both through motivation and organizational commitment. Work culture, work environment, motivation and organizational commitment simultaneously influenced performance. The results of path analysis shown that: Indirect effect of work culture to performance through motivation is more effective rather than its direct effect. Direct effect of work environment to performance is more effective rather than its indirect effect through motivation. Indirect effect of work culture to performance through organizational commitment is more effective rather than its direct effect. Indirect effect of work environment to performance through organizational commitment is more effective rather than its direct effect. Variabel intervening motivation in this research is able to mediated work culture to performance, but it unable to mediated work environment to performance. Variabel intervening organizational commitment in this research is able to mediated work culture and work environment to performance. Indirect effect of work culture to performance through organizational commitment is most of dominant path effect to performance. The total effect of work culture to performance through organizational commitment is most dominant total effect to performance.Keywords: Work culture, work environment, motivation, organizational commitment and performance.

Abstract

Two studies of zeolite application on oil palm seedlings for repair media of planting using a sandy soil type to seedlings media of oil palm have been conducted by The Oil Palm Research Center at experimental garden Aek Pancur, North Sumatra. Research I using Typic Udipsamment soil with 4 dose level of zeolite (0,50,100, and 150 g / polybag). Research II using tin tailings which treated zeolite soil amelioran materials, empty fruit bunch compost, dolomite, and also compared with the top soil is Typic Hapludult. The study I showed that application of zeolite is generally able to increase nutrient content in soil and soil cation exchange capacity inclined growth of better seeds. However, at doses of 150 g/polybag, zeolite application actually lowers the pH and increasing Aldd was followed by poor seedling growth. The study II using tin tailings as planting media, zeolite application has not yielded as good as empty fruit bunch compost applications to support seedling growth and nutrient uptake. Continued research related to determining the appropriate dose, and combination with other soil amelioran materials to increasing effectiveness of zeolite in improving the physical, chemical, and biological soil charachteristic as a medium sand fraction dominated planting of oil palm breeding is still very necessary.

Abstract

Zeolite has been known for improvement of soil fertility through increasing the cation exchange capacity. The objective of this research is to evaluate the application of zeolite for improvement of growth media and growth of oil palm seedling. The research has been conducted in the oil palm seedling research area of Aek Pancur using completely randomized design. The soils used for media are Typic Paleudults, Typic Udipsamments, and Typic Hapludults. The treatment composed of 4 zeolite dossages 0,50, 100, and 150 g/polybag. The results showed that application of zeolite to soils improved the properties of soils, especially cation exchange capacity. Application of zeolite as soil amelioration in the seedling of oil palm did not significantly improve the growth and absorption of nutrients during 11 months. In general, application of zeolite with the dosage of 100 g/polybag improve the growth and absorbtion of nutrients compared to without zeolite application. On the othe hand, application of 150 g zeolite/polybag decrease the growth and absorbtion of nutrients.
