Abstrak: Revitalization of Agriculture, Fisheries and Forestry (RPPK) launched by President on June 11, 2005 is as one of the Triple Track Strategy of the United Indonesia Cabinet in order to reduce poverty and unemployment and improving national economic competitiveness and preserving the resources of agriculture, fisheries , and forestry. Effective farmer groups to support the achievement of one of the Revitalization of Agriculture, Fisheries and Forestry. Appropriate leadership style in carrying out group activities support the achievement of the effectiveness of farmer groups. The purpose of this study is to describe the chairman's leadership style, identifying the factors that drive leadership style chair, analyzing the effectiveness of the group, and analyze the relationship with the chairman's leadership style effectiveness Mekarsari Farmers Group, Village Purwasari, Dramaga Subdistrict, Bogor Regency. The research was conducted in farmer groups located in the Village Mekarsari Purwasari, Dramaga district, Bogor regency. From this research can be seen that there is a relationship between individual factors with the leader's leadership style. It is also known there is a relationship between factor group with the leadership style of the group leader. In this study also can be seen that there is a relationship between leadership style group heads to the achievement of the group effectiveness.

Judul: Analisis Hubungan Gaya Kepemimpinan dengan Kinerja Kelompok Tani (Studi Kasus : Kelompok Tani Ternak Karya Sejahtera, Desa Karyawangi, Kecamatan Parongpong, Kabupaten Bandung Barat)
Abstrak: Revitalization of Agriculture, Fisheries and Forestry (RPPK) is one of the Triple Track Strategy of the government in order to reduce poverty and unemployment and improving the competitiveness of the national economy and preserve agricultural resources, fisheries and forestry. Development of farmer groups become an important part of the application by directing the agribusiness system, an increase in the role of leadership, the participation of farmers and other rural community members. This research was conducted to analyze the leadership style, the factors which drive leadership style, performance farmer groups, and the relationship with the leadership style of performance Karya Sejahtera farmer groups, in Karyawangi Village, Parongpong Subdistrict, West Bandung. The method used in this study is the Non-Probability Sampling, descriptive statistical analysis, and the Spearman rank correlation test. The results of this study indicate that the leadership style adopted by the laeder of Karya Sejahtera farmer group is a participative leadership style. Based on the descriptive statistical analysis of Karya Sejahtera farmer groups had an average score of moderate (3.45). Based on rank spearman test there are any relation betwen leaddership style of the group leader and Karya Sejahtera farmer group.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
