Judul: Pengaruh Gaya Kepemimpinan Terhadap Efektivitas Organisasi. Kasus Kelurahan Tegal Gundil Dan Kelurahan Bantar Jati, Kecamatan Bogor Utara, Kota Bogor. (Di Bawah Bimbingan Rilus A. Kinseng).
Abstrak: This research entitled “The Influence of Leadership Style toward Organizational Effectiveness (Cases of Tegal Gundil Administrative and Bantar Jati Administrative, Northern Districts Bogor, Bogor City.” The aim of this research was to examine the effect of leadership style on organizational effectiveness. The effectiveness of the organization refers to three of the four criteria organizational effectiveness according to Quinn and Rohrbaugh (1983), namely Human Relations Model, Internal Process Model, and Rational Goal Model. This research is descriptive. This research using a qualitative approach supported by quantitative data. The research was conducted in two different locations: Tegal Gundil Administrative and Bantar Jati Administrative. Conclusions can be drawn is that the leadership style adopted by both Lurah influence on motivation, job satisfaction, and employee performance. Lurah leadership style also has an effect internal process model such as communication and participation. And the leadership style considered to affect the success of the village.

Judul: Kasus Kelurahan Ciparigi, Kecamatan Bogor Utara, Kota Bogor
Abstrak: The purpose of this study is to identify Lurah’s leadership style which has been applied in every activities, to study factors that influence the application of Lurah’s leadership style, to study the performance of his subordinates in urban village Ciparigi, and to analyze the effect of these styles of leadership to his subordinates performance. This study combines two kinds of approach, quantitative approach (survey method) and qualitative approach. This study was conducted in the urban village of Ciparigi, Subdistrict of North Bogor, Bogor City, West Java. Based the funding of this study show, the dominant styles of leadership that were use by Lurah were the consultative leadership style and participative leadership style. Directive and delegative styles of leadership were also used in the selected activities. Factors which influence Lurah’s style of leadership in urban village Ciparigi are leader characteristics, subordinates characteristics, and the situation in the organization. The performance of urban village Ciparigi is quiet high, 75% of subordinates have a high performance of work. The application of various styles of leadership, especially the consultative and participative style, effectively affect the subordinates performance, that produces a high performance of work, whether in application of internal duty or society services.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
