Abstract

Improvement and development of the quality of education is an issue that is always demanding attention. Absorption rates subjects received between students with each other is different, there are no high-low berkemampuannya. This is a challenge for teachers to be able to maximize the absorption of each student. The problem in this research is how to plan, create or produce, and test the software in the form of interactive teaching materials for teaching engineering subjects power installations with macromedia flash and whether use of interactive teaching materials suitable for use in the SMK. The research objective to be achieved is to plan, create or produce, and test the software shaped interactive teaching materials to aid learning in subject matter presentation "Power Installation Techniques" at SMK. Data collection techniques used in this study with the completion of interviews, documentation, and questionnaires / checklist. Test results overall instructional media respondents, from multimedia expert stated 84.30% by both criteria, 81.79% of the teachers stated by both criteria, of the students in the two variables, the variable response of the students stating 78.19% by both criteria and variable 77.04% student attitudes expressed by both criteria. Test results to all respondents said this interactive teaching materials fit for use as teaching materials in vocational and has met with success indicators percentage average of 81.23% or better category. Program materials should be used as supplementary teaching materials for engineering subjects power installations. Need further research based on the development of electronic learning materials program with other models as an extra means of learning.

Abstract

 Penggunaan media pembelajaran memiliki pengaruh yang signifikan bagi siswa dalam memahami materi yang diajarkan. Belum tersedianya media pembelajaran dalam bentuk trainer pada mata pelajaran instalasi listrik menyebabkan siswa dalam memahami materi yang disampaikan oleh guru masih kurang maksimal dan dalam kegiatan praktiknya siswa masih mengalami kesulitan. Penelitian ini bertujuan untuk mengembangkan trainer instalasi penerangan sebagai media pembelajaran instalasi listrik program keterampilan Elektronika di MAN Kendal, mengetahui tingkat kelayakan trainer instalasi penerangan yang dikembangkan, dan mengetahui perbedaan hasil belajar siswa antara sebelum dan setelah menggunakan trainer instalasi penerangan. Metode penelitian yang digunakan adalah metode penelitian dan pengembangan  (Research & Development). Untuk mengetahui kelayakan trainer instalasi penerangan dilakukan tiga tahapan, yakni (1) pembuatan trainer instalasi penerangan (2) uji kelayakan media (3) serta uji coba produk. Dalam penelitian ini yang bertindak sebagai responden adalah 3 guru program keterampilan elektronika MAN Kendal dan 23 siswa workshop program keterampilan MAN Kendal. Instrumen penelitian yang digunakan berupa angket uji kelayakan media, angket respon siswa dan lembar observasi. Berdasarkan hasil penelitian ditunjukkan bahwa Trainer instalasi penerangan yang telah dikembangkan layak digunakan sebagai media pembelajaran instalasi listrik program keterampilan Elektronika di MAN Kendal. Ketercapaian kelayakan trainer dapat dilihat dari hasil analisis uji kelayakan oleh tim ahli yang memperoleh persentase sebesar 80% dengan kategori baik, serta hasil respon siswa terhadap trainer instalasi penerangan yang memperoleh persentase sebesar 86% dengan kategori sangat baik. Ada perbedaan signifikan, hasil belajar siswa antara sebelum dan setelah menggunakan trainer instalasi penerangan sebagai media pembelajaran instalasi listrik pada program keterampilan Elektronika di MAN Kendal.

Abstract

Kebakaran merupakan bencana yang sering terjadi di kota-kota besar baik pada kawasan pemukiman penduduk, gedung perkantoran, pabrik, pusat pembelanjaan dan lain-lain. Setiap tahunnya peristiwa kebakaran mengalami peningkatan seiring bertambahnya penduduk dan bangunan gedung atau rumah tinggal. Oleh karena itu perlu dilakukan penelitian untuk mengetahui dan membuktikan apakah benar peralatan instalasi listrik sebagai sumber terjadinya korsleting listrik atau beban lebih yang dapat menyebabkan kebakaran pada rumah tinggal atau gedung. Pengambilan data dilakukan dengan metode eksperimen yang dilakukan di Laboratorium Fakultas Teknik UNNES untuk mencari pengaruh perlakuan tertentu terhadap yang lain dalam kondisi yang terkendali. Metode analisis data yang digunakan adalah metode analisis deskriptif. Hasil penelitian dan pembahasan yang telah dilakukan, untuk pengujian kabel kabel NYA dan kabel antena sudah mengeluarkan bau kabel terbakar dan asap dengan temperatur 68,9 0C dan 67,4 0C sebelum gawai proteksi putus. Sama halnya saat pengujian sambungan kabel kendor dan penumpukan stop kontak sudah meleleh dengan temperatur 129,7 0C sebelum gawai proteksi putus.Berdasarkan hasil penelitian dan pembahasan disimpulkan bahwa penyebab kebakaran tertinggi diakibatkan oleh korsleting listrik pada peralatan instalasi listrik terutama pada pemasangan instalasi listrik yang tidak sesuai standar PUIL 2000 dan instalasi listrik yang sudah berumur tua. Selain itu penggunaan, pemasangan dan perlakuan pada peralatan listrik yang kurang baik juga menyebabkan korsleting listrik. Catastrophic fires that often occur in large cities, both in residential areas, factories, markets. shopping center, and others. In every years, fire continued to increase with increasing population, building or home in big cities. Its necessary to investigate and prove it as a source of electrical installation equipment electrical short circuit, or load that could cause fires in residences or buildings. Data collection was performed by the method of experiments carried out in the Laboratory of the Faculty of Engineering UNNES to look for the effect of a particular treatment against the other under controlled conditions. Data analysis method used is descriptive analysis method. Results and discussion of research has been done, the quality of electrical installation equipment materials will determine the ability of the insulation resistance. Increasingly ugly insulating materials, it will be the worse its ability custody. To test the cable and antenna cables, cable has issued a burning smell and smoke with a temperature of 68.9 ° C and 67.4 ° C before dropping MCB protection. Similarly, when a loose cable connection testing and buildup outlet. cable connection and outlet melt, with a temperature of 129.7 ° C before dropping MCB protection. based on the results of research and discussion, it was concluded that the cause of the fire caused by electrical short circuit highest in electrical installation equipment. especially on non-standard installation PUIL 2000 and old electrical installations. in addition, the use and improper installation of electrical equipment also lead to electrical short circuit.
