Abstract

AbstractThe purpose of this research was to find out whether the application of  Problem based learning was effective in teaching a statistics materials to the eleventh grade students of SMA Negeri 1 Sungai Raya. This research is classified as a pre-experimental and conducted in form of one case study or post-test only design. The population of this research were 162 students of eleventh grade, and the samples were 40 students. Purposive sampling was used to choose the sample. The result of the data analysis showed that the study result was not reached, learning activity was quite active and student gave a positive respons. Based on the research findings, it can be concluded that the application of  Problem based learning was  effective in teaching a statistic materials  to the grade XI 2 students of SMA Negeri 1 Sungai Raya because the study result was reached and learning activity was quite active.Keyword: Problem Based Learning, Response, Student Activities

Abstract

Teknologi terbarukan mengenai penggunaan beton ringan telah banyak dikembangkan. Akan tetapi dalam penggunaan beton ringan tersebut terdapat beberapa kendala baik dari segi pemasangan, biaya yang tinggi dan dari segi waktu pengerjaannya. Oleh karena itu muncul suatu gagasan untuk mengembangkan penggunaan beton ringan struktural pada bangunan tinggal. Dalam hal ini penggunaan beton ringan yang dikembangkan merupakan beton ringan dengan foam sebagai pelat lantai rumah tinggal.Penelitian ini merupakan penelitian yang berfokus pada perbandingan campuran beton ringan foam terhadap keberhasilan bentuk beton ringan saat pembukaan bekisting 24 jam. Campuran yang digunakan pada penelitian ini yaitu   1:2:0.375 untuk campuran pertama dan 1:1:0.25 untuk campuran kedua. Berdasarkan hasil penelitian ini dari 13 percobaan didapatkan campuran pertama gagal dalam menghasilkan beton ringan foam sedangkan pada campuran kedua berhasil dalam menghasilkan beton ringan foam.Kata Kunci: Beton ringan foam, pelat lantai, campuran.

Abstract

This study investigates the performance of android applications developed using Java and Kotlin in consuming API. Driven by the need for responsive and efficient android applications and the potential impact of runtime performance differences between Java and Kotlin programs, this research employs an experimental method with a quantitative approach. Data is collected through Instrumented Tests and Android Studio tools on two smartphones with different specifications. Parameters measured include data download speed, memory allocation, execution time, serialization/deserialization time, application size, and lines of code. Results indicate Java's superiority in download speed and data serialization, while Kotlin demonstrates conciseness in code size. Performance varies depending on device specifications. The choice of programming language depends on the application's needs and priorities. Java is optimal for applications prioritizing download speed and data serialization, while Kotlin suits those focused on code efficiency. This study provides recommendations for PANDA application developers and future research.
