Abstract

Eksplorasi sumber daya konvensionai untuk pembangkittenaga listrik dirasakan sudah tidak dapat memenuhi jumlahkebutuhan tenaga listrik yang makin meningkat tajam. Tahur»yang lalu (1992), Perusahaan Listrik Negara, sudah sulit memenuhipermintaan sambungan listrik para konsumen. PembangunanJangka Panjang Tahap II mengisyaratkan proses industrialisasiakan diprioritaskan. Dan untuk menopang ha~tersebut, tersedianya jumlah energi listrik yang cukup danhandal mutlak diperlukan. Saat ini pemerintah berupaya menc~ri sumber daya alam alternatif; salah satunya Uranium.Uranium sebagai bahan baku Pusat Listrik TenagaNuklir (PLTN) merupakan sumber claya a1am yang mempunyaiaspek menguntungkan untuk memenuhi kebutuhan energilistrik yang makin meningkat,' dan sekaligus mempunyai aspekyang merugikan karena ancaman radioaktif yang dapat memusnahkanmanusia dan makhluk lain di sekitarnyi:L. Sejakper mulaan perkembangan teknologi nuklir telah disusun kode,standar dan kriteria keselamatan yang sangat ketat, tidakseperti teknologi Iainnya. Bahkan peraturCLn keselamatan ternyatatelah berkembang mendahu1ui realisasi teknik dad teknologinuklirnya sendiri. Oleh karena itu, sejak dini perIn diantisipasiusaha-usaha pencegahan timbulnya pf.tensi bahi:lyaPLTN demi kelestarian ekosistem yang ~da.

Abstract

The competencies of vocational high school (VHS) graduates, especially in terms of character have not met its standards. This study aims to develop a character-based assessment model for VHS in the form of a guide and procedure. Borg Gall’s (1989) model with the following stages was utilized: (1) needs analysis, (2) planning, (3) development, (4) phase I trial, (5) phase II trial, (6) evaluation of model effectiveness, and (7) final product development. This study involved some experts in the model validation. Trials were done to teachers and principals in eight VHSs in Yogyakarta Special Province, Indonesia in 2017 (first trial), and those from 42 VHSs throughout Java island, Indonesia in 2018 (second trial). Data were collected by questionnaires and interviews and analysed by quantitative and qualitative descriptive statistics. This study suggest that, overall, the model is appropriate and feasible to use, proven by (1) the assessment guide is categorized as ‘very appropriate’ (Mean 3.55; SD .52); (2) assessment procedure achieves an ‘very appropriate’ category (Mean = 3.60; SD = .51); and (3) effectiveness of the assessment model in trial 1 is in the ‘very appropriate’ category (Mean 3.43, and SD .51), and in trial 2 is in the ‘appropriate’ category (Mean 3.38, SD .53).

Abstract

The teacher certification program has been implemented since 2007, yet the society has not optimally experienced the quality improvement of secondary education in Industry 4.0. This study aims to examine vocational and senior high school teacher professionalism in the age of Industry 4.0 in developing learning. This study employed the survey method with quantitative descriptive analysis. The sample of this study was taken from two provinces in Indonesia, namely Yogyakarta Special Region and West Borneo. The data were collected from 113 vocational and senior high school teachers using random purposive sampling. The instruments used in this research were open-ended and close-ended questionnaires. The results of this study show that there is still a low number of teachers with a Master’s degree; however, teachers participate in various capacity building training programs. Moreover, the most common training programs for the teachers are on classroom action research, scientific journal publications, curriculum development, and updating teaching materials. Furthermore, it is found that the number of journal articles published by vocational and senior high school teachers in the two provinces is still low, and as a result, bottleneck problems may occur in their career promotion.
