Abstract

he development of the DIVA Learning Management System learning model is an increase in student understanding based on problems because learning algorithms and programming is indicated to be low in students' understanding that is abstract in the subjects of algorithms and programming. For this reason, the purpose of this study is to develop a DIVA Learning Management System model that has effectiveness. The methodology used is quasi experimental design in the form of nonequivalent pretest-posttest control group design. This study found the DIVA Learning Management System learning model with the syntax: a) Display; b) Information Search; c) Virtual Problem Solving; and d) Appraisal, and products from: (1) DIVA learning management system learning model (2) learning tools; (3) modules; and (4) learning media. Analysis of research data shows the learning model DIVA Learning Management System In the effectiveness test of media use for lecturers 92.3% is effectively used and for student learning outcomes with pre-test and post-test test scores can be seen from the achievement score of each respondent. The gain score results indicate the achievement score is at the level of 0.486 with the interpretation that overall an increase in scores after being given treatment to respondents. Based on the results of the data analysis above, it can be concluded that the model developed meets the feasibility to be used.

Abstract—This study aims to develop training kits Measurement of electricity is valid, practical, and effective On the subject MPKE Class X TITL at SMK Muhammadiyah 1 padang The method used is research and development. The subject of this study is learning media Training Kits measurement of electricity and respondents are students of class X TITL 1 SMK Muhammadiyah 1 Padang and subject teachers MPKE SMK Muhammadiyah 1 Padang. Based on the research results obtained the validity from validator team that validation result with validator valid category. Test effective obtained from the results of classical completeness Seen from student learning outcomes. Posttest result of students who passed above KKM 21 students from 28 students Student scores below KKM 7 students, then the result of the 28 students who follow posttes 21 students graduated 21 students who graduated, Being in the effective category. Based on this research can be concluded that Training Kits is valid practical, and effective use to teach on subjects MPKE and can increase students' interest in learning so that it can bring the impact of increasing student learning outcomes.

Abstract

Sebuah desain bangunan yang baik harus memperhatikan karakteristik geografis, kondisi lingkungan dan iklim setempat dimana bangunan didirikan. Salah satu faktor penting yang dapat mempengaruhi kenyamanan termal bangunan adalah pengaruh inersia termal tanah dan material selubung bangunan. Tujuan penelitian ini adalah untuk menganalisa pengaruh inersia termal tanah terhadap perubahan temperatur dan kenyamanan penghuni didalam ruangan. Pada bagian pertama, karakteristik bangunan dan pemodelan numerik akan dijelaskan yang dilengkapi dengan data iklim lokasi dimana studi kasus dilakukan. Perpindahan panas yang terjadi dari bangunan menuju tanah dan sebaliknya digambarkan secara detil pada bagian selanjutnya dengan menggunakan pendekatan model perpindahan panas tiga dimensi. Hasil simulasi numerik menggunakan TRNSYS (R) menunjukan bahwa inersia termal tanah berpengaruh secara signifikan terhadap suhu dan kenyamanan ruangan. Tanah dengan konduktivitas dan kapasistas termal yang baik mampu menurunkan tingkat ketidaknyamanan ruangan hingga 21.9%.
