Judul: Pengembangan Kompetensi Penyuluh Pertanian di Provinsi Nusa Tenggara Timur
Abstrak: Pembangunan pertanian di Indonesia tidak bisa dipisahkan dari peranan penyuluh pertanian. Dalam pembangunan pertanian peranan penyuluh pertanian adalah memberdayakan petani agar bisa menolong dirinya sendiri. Penyuluh pertanian bekerja bersama petani agar mereka mampu mengembangkan potensi dirinya sehingga mampu bertani lebih baik, berusaha tani lebih baik, dan mencapai kehidupan yang lebih sejahtera. Untuk mencapai tujuan-tujuan itu, seorang penyuluh harus memiliki kemampuan dalam melaksanakan tugasnya yang disebut kompetensi. Ada empat tujuan utama dari penelitian ini, yakni: pertama, untuk menganalisis pengaruh faktor internal dan eksternal penyuluh terhadap kompetensi mereka dalam melaksanakan tugasnya; kedua, untuk menganalisis pengaruh kompetensi terhadap kinerja penyuluhan; ketiga, untuk menganalisis pengaruh karakteristik individu petani dengan penilaian kinerja penyuluhan; dan keempat untuk menyusun strategi pengembangan kompetensi penyuluh di Provinsi Nusa Tenggara Timur ke depan. Faktor internal penyuluh dalam penelitian ini adalah karakteristik individu penyuluh seperti pendidikan formal, pendidikan non formal, umur, masa kerja, sifat kosmopolitan, motivasi, dan pendapatan; sedangkan faktor eksternal penyuluh di sini adalah diklat penyuluhan, lingkungan dan struktur organisasi penyuluhan. Sebagai seorang pemberdaya masyarakat, seorang penyuluh harus memiliki kompetensi dalam hal: (1) menyiapkan penyuluhan, (2) melaksanakan penyuluhan, (3) membuat evaluasi dan pelaporan pelaksanaan penyuluhan, (4) mengembangkan penyuluhan, (5) berkomunikasi, dan (6) berinteraksi sosial. Karakteristik individu petani terdiri dari pendidikan formal, pendidikan non formal, umur, sifat kosmopolitan, kategori adopter, dan pendapatan.

Judul: Pengembangan Kompetensi Penyuluh Pertanian Lulusan Pendidikan Jarak Jauh Universitas Terbuka
Abstrak: Agricultural extension workers who are competent in aspects of their personality, task, andragogic, dan social interaction, potentially more capable of providing satisfactory service to the farmers. The development of these competencies, one of which can be obtained through education at Universitas Terbuka. The objectives of this study are : (1) to identify the profile of Agricultural Extension Workers graduated from UT; (2) to identify the level of competencies of agricultural extention agents and factors contributing to their competencies; (3) to identify the level of performances of agricultural extention workers and factors contributing to their performances; and (4) to formulate strategies for development of agricultural extention agent competencies. Data were collected in July through December 2008. A survey technique was implemented among 118 agricultural extension agents who were graduated from UT and among 88 farmers in four different locations, namely Serang, Karawang, Cirebon, and Tanggamus. By using Indepth interview, a qualitative information were also collected in order to elaborate the results. Data was analyzed by using descriptive, regression, and path analysis. The findings indicated that : (1) The profile of UT’s alumni was vary in individual characteristics, learning activities at UT, learning sources from others, and environment factors; (2) UT’s alumni had a medium level in personal, tasks, andragogic, and social competencies. Factors contributing to their personal competencies were age, working experience, and farmer’s needs. Factors contributing to their tasks competencies were motivation, interaction with learning materials, and interaction in study group. Factors contributing to their andragogic competencies were tutorial, learning facilities, and training. While factors contributing to their social competencies were age and subject matter; (3) UT’s alumni had a medium level in their performance. Factors contributing their performances were interaction with learning material, tutorial, interaction in study group, and personal, task, andragogic, and social competencies. This study suggests several strategies in developing competencies for agricultural extension workers at Universitas Terbuka. Those strategies are focused on enhancing: (1) the cognitive level of their tasks, andragogic, and social interaction, (2) the affective level of their personality and tasks; and (3) the psychomotor level of their personality, tasks, andragogic, and social interaction. Those can be achieved through developing the learning activities at UT.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
