Non-formal education: is it relevant or obsolete?
Introduction 
The importance of non-formal education in the Pacific Region cannot be overemphasized. This presentation argues that it is very relevant and contributes significantly to national developments and in its flexible approaches, seen as a means of addressing some of the pertinent global issues facing the nations in the Pacific Islands. As global issues affect the people culturally, socially, economically and politically, the role of non-formal education becomes very critical in how these issues are addressed. The role of non-formal approaches to adult learning, gender equality, health, sustainable environment and peace and conflict resolution are being widely advocated by both government and non-government organizations in the Pacific Island nations. 
Broadly conceived, non-formal education is not a new concept but an educative process that has been in existence in pre-literate societies. Increasing evidence exists to substantiate the claim that non-formal education is an old concept with a new name. In the Pacific Island nations non-formal education is integrated in the life style of the people. This article first examines non-formal education in the traditional context, and then discusses the reasons for NFE in the region, its conceptualization, and its contribution to the needs in the Pacific Region.
MODEL PEMBELAJARAN MAGANG ( STUDI PADA PENGRAJIN LOGAM DI SENTRA HOME INDUSTRI LOGAM KELURAHAN KEJAMBON KECAMATAN TEGAL TIMUR KOTA TEGAL )
Tujuan dalam penelitian ini, yaitu: (1) Untuk mendeskripsikan proses pembelajaran magang di Sentra Home Industri Logam Kelurahan Kejambon Kecamatan Tegal Timur Kota Tegal; (2) Mendeskripsikan model pembelajaran magang di Sentra Home Industri Logam Kelurahan Kejambon Kecamatan Tegal Timur Kota Tegal; (3) Mendeskripsikan apa saja hasil yang diperoleh pemagang (peserta didik) setelah mengikuti pembelajaran magang di Sentra Home Industri Logam Kelurahan Kejambon Kecamatan Tegal Timur Kota Tegal. Penelitian menggunakan metode kualitatif dengan teknik pengumpulan data yang digunakan: wawancara, observasi, dokumentasi, dan subyek penelitian ini berjumlah 9 orang yaitu: 2 orang pemilik industri, 2 orang tutor, 2 orang warga belajar, dan 3 orang pemagang yang telah mandiri. Analisis data yang digunakan adalah kualitatif. Hasil yang diperoleh dalam penelitian ini: (1) proses pembelajaran dimulai dari tahapan pemberian pekerjaan yang ringan hingga praktek secara mandiri setelah melihat tutor mendemonstrasikan terlebih dahulu; (2) . Model pembelajaran yang ada di pembelajaran magang ini adalah model belajar pendidikan orang dewasa dengan kegiatan praktek langsung;  (3) hasil yang diperoleh setelah mengikuti proses magang adalah bertambahnya pengetahuan dan ketrampilan, serta adanya sikap mandiri dari pemagang untuk membuka usahanya secara mandiri di rumah masing-masing. The purpose of this research, include: (1) To describe the process of learning internship in the the Sentra Home Industri of Metal Village Kejambon Eastern District of Tegal, (2) Describe the apprenticeship model of learning in the Sentra Home Industri of Metal Village Kejambon Eastern District of Tegal; (3) Describe any results obtained interns (students) after participating in learning internship in the the Sentra Home Industri of Metal Village Kejambon Eastern District of Tegal. Research using qualitative methods of data collection techniques were used: interviews, observation, documentation, and the subject of this study is 9 people: 2 industrial owner, 2 tutors, 2 learners and 3 interns who are independent. Data analysis is qualitative. The results obtained in this study: (1) the learning process starts from the stage of the employment of mild to practice independently after seeing the first demonstration tutor; (2). Model of learning in this internship is learning learning model of adult education with hands-on activities, (3) the results obtained after following the internship process is increased knowledge and skills, as well as the independent attitude of interns to begin operations independently in their homes each.
Chemical, biological, and immunological characterization of mono- and diiodothyrotropin releasing factor.
Abstract Iodination of thyrotropin releasing factor (TRF) with chloramine-T and NaI at pH 7.5 produces both mono- and diiodo-TRF as well as unreacted TRF and I − . The four compounds can be separated by ion-exchange chromatography on SP-Sephadex C-25, using a stepwise gradient of 0.01 m MH 4 OAc at pH 3.5, 5.2 and 7.2. The monoiodo-TRF was characterized by nuclear magnetic resonance, mass spectra, and elemental analysis as [Im-5-iodo-His 2 ]-TRF while the diiodo-TRF was similarly characterized as [Im-2,5-diiodo-His 2 ]-TRF. Both iodination products showed no thyrotropin releasing activity at doses up to 1 μg in the in vivo mouse bioassay. The specific binding of mono- and diiodo-TRF was measured against three different TRF antisera. In the absence of TRF, antisera A and C bound more diiodo-TRF than monoiodo-TRF while antiserum B seemed to bind both tracers equally. In all cases steeper curves were produced when diiodo-TRF was displaced by synthetic TRF.
