Judul: Performance Determinants of Agricultural Extension in the City Tidore Islands North Maluku province
Abstrak: The role of agricultural extension agent from 1978 until the 1980's showed an important role in the development of national economy. In the 1990's the perceived role of the instructor began to decline, both in quantity and quality (performance level). The condition is occurring nationwide, including in the City Tidore Islands North Maluku province. Therefore we need a study that aims to analyze the factors thought to affect the performance of extension workers and formulating appropriate counseling strategies based on the implementation of the determinants of performance extension. Data collection conducted in mid-May through June 2011 thousands through census methods. The study population was defined as many as 56 people 67 people from the extension of existing civil servants. The results showed a correlation factor of age, period of employment, training, instructor perceptions of the tasks / jobs, media utilization, reward systems, active community participation, support supervision monitoring, planning, implementation, and evaluation of extension programs, applying principles of adult learning, and communication skills real contact with the performance of agricultural extension. The analysis showed a factor of training, perceptions of job/task, use of the media, community participation, and implementation of extension programs have real impact on the performance of agricultural extension. The average performance of extension agents were the category of being, where the extension is not optimal in planning, implementing and evaluating activities properly instructed. This is caused by a lack of creativity, initiative, and the ability of trainers to build cooperation and communication with the target extension. The implementation of agricultural extension that is not optimal in the City Tidore Islands affected several determinants of performance of extension, namely: (1) lack of competence in aspects of the implementation of extension programs. (2) lack of extension agents utilize the available media, (3) perception of extension agents to the task / job, (4) the intensity of training, and (5) active participation of the community.

Judul: Analysis of Agricultural Extension Institutions in the Province of Riau
Abstrak: This era of regional autonomy with its emphasis on the efficiency of institutions and improved human resources has made some changes in the extension paradigm. Different regions have different responses. Some still maintain their extension institutions as they were in the past while others have changed the extension system. The varied institutions that are responsible for agricultural extension have certainly resulted in different performance, and consequently affected the main target of agricultural development, namely farmers. This study was intended to: (1) identify the structure of agricultural extension institutions in the regional autonomy era in the Province of Riau, (2) analyze the implementation of agricultural extensions in different institutions, and (3) analyze the effect of different extension implementation on the performance of extension workers and the degree of technological application among farmers. This is a descriptive study through a survey conducted from March to April 2008 in three regencies/towns, namely Pekanbaru, Kampar Regency and Pelalawan Regency.

Judul: Perubahan Fase Padat pada Pembentukan Hidroksiapatit Akibat Suhu
Abstrak: Hidroksipatit [HAp, Ca10(PO4)6(OH)2] adalah salah satu bahan biomaterial yang dapat digunakan untuk implan tulang buatan karena memiliki komposisi yang sama dengan tulang manusia, bersifat bioaktif dan biokompatibilitas yang baik. HAp sintesis dengan menggunakan metode kering dan metode kering modifikasi sonikasi dari reaksi antara serbuk CaO hasil pemanasan cangkang kerang darah 1200 ºC selama 2.5 jam dan diamonium hidrogen fosfat (NH4)2HPO4 sebagai sumber fosfat. Difraktogram sampel menggunakan metode kering selama 2.5 jam pada suhu 400 ºC menghasilkan fase HAp, β-TCP, AKA, OKF, Ca(OH)2, dan CaO, pada suhu 600 dan 800 ºC terbentuk fase HAp, β-TCP, AKA, OKF, dan CaO, pada suhu 1000, 1200, dan 1250 ºC (serbuk dan pelet) terbentuk fase HAp dan β-TCP. Difraktogram sampel bersumber CaO cangkang kerang darah dan CaO komersial terbentuk fase HAp, β-TCP dan AKA. Metode kering-sonikasi (pelet) pada suhu 400 1250 serta 1250 ºC (serbuk) selama 3 jam menghasilkan fase HAp, β-TCP. Pada sampel 1250 ºC (serbuk) metode kering-sonikasi menunjukkan puncak tertinggi 2θ adalah hidroksiapatit dengan nilai 2θ 31,835º dan 32,918º, dan memperlihatkan morfologi permukaan yang lebih halus dan homogen berdasarkan mikroskopi payaran elektron.
