Abstract

Difficulties experienced by students in learning Physics include both students and teachers not being able to recognize their learning styles and students' lack of creativity in learning which will have an impact on learning outcomes. The aim of this research is to analyze whether there is a relationship between learning style and creativity with high school physics learning outcomes. This type of research is descriptive research with a correlational quantitative approach. The research population is State High Schools in Payakumbuh. Sample selection applies Purposive Cluster Sampling by selecting 1 from each school ranking, high, medium and low. The instruments used are the learning style questionnaire consisting of 26 items and the creativity questionnaire consisting of 27 items. The data analysis technique uses prerequisite analysis tests, namely the normality test; homogeneity test and hypothesis test using linearity test, multiple linear regression test and correlation test. The results obtained are as follows: (1) there is a positive relationship between learning style and learning outcomes. (2) there is a positive relationship between creativity and learning outcomes at a significance level of 5% or 0.05.

Abstract

Perisai neutron termal merupakan suatu struktur atau material yang memegang peranan penting dalam proteksi radiasi neutron termal untuk menghindari dampak negatif dari paparan radiasi secara langsung, baik terhadap lingkungan maupun kesehatan manusia. Pada penelitian ini, digunakan silikon-karet sebagai material utama perisai neutron, sedangkan asam borat berfungsi sebagai penyerap neutron termal, sehingga keakuratan informasi mengenai sifat redaman dan proteksi perisai neutron yang dirancang menjadi sangat penting. Beberapa parameter perisai radiasi yang harus dievaluasi dalam menentukan kinerja material perisai neutron yang difabrikasi antara lain faktor redaman massa, faktor redaman linier, dan lapisan nilai setengah. Perangkat lunak komputasi NGCal digunakan untuk mensimulasikan sifat dan parameter material perisai. Berdasarkan perhitungan yang dilakukan, dapat disimpulkan bahwa perisai dengan efisiensi tinggi adalah perisai dengan penggunaan rasio sorben yang lebih tinggi yaitu asam borat, sedangkan apabila rasio karet silikon lebih besar dari asam borat maka tingkat efisiensi penyerapan menurun, tetapi fleksibilitas mekanis perisai akan semakin baik. Ketebalan perisai neutron berhubungan langsung dengan nilai MAC dan LAC, dimana semakin tebal perisai maka nilai MAC dan LAC akan semakin tinggi, hal ini menyebabkan efisiensi penyerapan neutron termal oleh perisai neutron akan semakin meningkat apabila asam borat mendominasi pada komposit, namun apabila ketebalan perisai didominasi oleh karet silikon maka efisiensinya akan semakin menurun.
