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: Persepsi Anggota Kelompok Tani Padi terhadap Kepemimpinan Ketua Kelompok Tani di Kabupaten Kebumen, Jawa Tengah
Abstrak: In general, the behaviour of farmer group leaders strongly influences the changes in his group behaviour. If the leader is effectively influencing his members, they will behave as desired. Therefore, the leadership of farmer groups becomes a strategic issue on agricultural extension methodology through group approach. The farmer group leader could act for some leadership functions and figures to motivate and mobilize members to perform various activities to achieve the group goals. Perceptions related to the individual's opinions and judgments of a stimulus that will lead to motivation, willingness and feelings toward the stimulus. The correct perception of an object is necessary, because the perception is the basis of the formation of attitudes and behaviour. Thus, a good perception of the group members on the leadership of their group leaders is one of the main indicators of the success of a leader in bringing about the success of his farmer groups. This research aims to: (1) analyse the perception of group members on the leadership of farmer group leaders, (2) analyse the correlation between internal factors in the group members and their perceptions on the leadership of their group leader, (3) analyse the correlation between external factors in the group members and their perceptions on the leadership of their group leader, (4) analyse the success of farmer groups, and (5) analyse the correlation between perceptions of group members on the leadership of their group leader and the success of farmer groups. The design of this research is using methodology of survey to explain the correlation among the variables of this research. The population in this research are all farmers who are members of paddy farmer groups in Kebumen, Central Java Province. The respondent recruited by using stratified random sampling method based on class (typology) of abilities of farmer groups set by the Ministry of Agriculture, namely: Beginners, Intermediates 1, Intermediate 2, and Advanced (Pemula, Lanjut, Madya and Utama). The number of farmer groups (respondents) observed were 12 groups with details of three farmer groups in each typology of farmer groups, then 10 members from each group selected, so the total number of respondents was 120 farmers. The research was conducted from August to November 2012. The data analysis includes: (1) descriptive analysis: the frequency distribution and different test of non-parametric Kruskal-Wallis, and (2) inferential analysis: Rank Spearman correlation. Analysis helped by SPSS software version 20.0. The result of this research shows that the perception of members on the leadership of the farmer groups’ leader is high; the group leader has performed his function as a group leader well. The higher the grade of ability of the farmer groups, the perception of members on the leadership of their group leaders tends to become better. Internal factors of the group members that consist of age, formal education, land owned, motivation, and a cosmopolitan issue of the area have real positive correlation to the perception of members on the leadership of the farmer groups’ leaders. The external factors of the group members that consist of the availability of information, the role of agriculture extension worker,

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.
