Judul: Hubungan Gaya Kepemimpinan Dengan Kinerja Pegawai Pemerintah (Kasus Suku Dinas Peternakan, Perikanan, dan Kelautan Kota Administrasi Jakarta Utara)
Abstrak: The purpose of this research was to study about the relationship between leadership and the performance of government employees in some offices of livestock, fishery, and marine resources in North Jakarta. This study used a quantitative approach by using a census method and was supported by qualitative data. An individual respondent was a civil servant who had been working there. It focused on three points of analysis. They were a leadership type owned or used by a leader, the employees performance, and the relation among them. Based on the result of study, a dominant leadership type used was participatory. Furthermore, a leader also used consultive and delegative leadership type. They used several leadership types in various conditions and in accordance with the character of employees. It indicated that most employees had a good performance. There was a close relation between factor of leadership type anad employees performance. At last, it could be concluded that a leadership type used by a leader would improve the employees performance.

Judul: Peran Gaya Kepemimpinan dan Budaya Organisasi terhadap Kinerja Aparatur Pemerintah Kabupaten Padang Lawas Utara
Abstrak: Human resources of organization is a vital asset because of its role in the implementation of the strategy is very important, which is the subject of implementing organizational strategy. They have potential as ideas, thoughts, experties, feelings, desires, educational background, age, sex and various other things that heterogeneous, which if their potentials brought into an organization can be utilized and optimized in carrying out the work to achieve organizational goals. One of the things that must be considered in the implementation of the work, namely the achievement of good performance, accordance with the applicable performance standards and desired by the organization, and in accordance with the vision and mission of the organization. However, that all the civil servants can achieved the desired performance, many factors that can influence it,such as leadership styles, organizational culture, compensation, motivation, work climate, organizational commitment, and so forth. This study will only discuss about leadership styles and organizational cultural factors that may effect the performance of the civil servants. The appropriate leadership style to the situation and condition of the organization, civil servants will be more excited in performing their duties and obligations as well as having their needs fulfilled expectations. Good and condusive organizational culture to an organization can aslo affect the civil servants in their activities as well as directly affecting their performance. This research was done at Local Government of North Padang Lawas, North Sumatera. In this research, the subject was all local government civil servants of North Padang Lawas, North Sumatera. The technique of samples used was cluster purposive sampling so that the sample in this research was 38 clusters (SKPD) in which of every clusters were taken as the sample. Data analysis in this research used SEM method (Structural Equation Modeling) by using LISREL program. From the analysis result structural research models, it could be concluded that leadership styles influenced the performance positively and significantly. Organizational cultures influenced both the leadership styles and performance negatively also unsignificantly. It meant that the higher leadership style, the better performance would be and vise versa. However, the organizational cultures, will not give significant effect on both leadership style and performance.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
