Abstract

This article presents the results from integrating Social Emotional Learning (SEL) through cooperative learning and contextual approach in chemistry learning. This study was conducted on 10th-grade students in the academic year of  2016/2017. Collaborative learning, as well as the use of real-life scenario, are some of the teaching practices for facilitating Social Emotional Learning (SEL) and promotes students' social-emotional competenciesthat aligned with affective competencies in Indonesia’s 2013 curricula. The proposed teaching practices also answer the challenges faced by the implementation of the 2013 curricula, finding proper teaching practices to integrate to develop student’s character through learning activity. The empirical work of the study is based on a qualitative approach. Six Group Investigation’s stage integrated with the use of real-life scenario was analyzed through various method such as observations, interviews, reflective journals, and student’s worksheets answer. The results found that students showed positive attitudes and perspective’s change towards chemistry learning, establish positive relationship with peers, cooperative skill, tolerance, and responsible decision making by considered himself, others, and community within the learning process.

Abstract

Salmonella enterica serovar Typhi merupakan penyebab demam tifoid atau penyakit tifus pada manusia. Mekanisme molekuler patogenesitas Salmonella merupakan sistem yang kompleks dan diatur oleh sejumlah gen dan faktor-faktor virulen. Salah satu gen tersebut adalah dnaK yang mengatur sintesis Heat Shock Protein 70 (HSP70). Penelitian ini bertujuanuntuk memperoleh gen HSP70 yang berukuran 1,9 kilobasa dari bakteri Salmonella enterica serovar Typhi. Gen tersebut dapat digunakan untuk pengembangan vaksin tifus maupun diteliti lebih lanjut untuk mengungkap fungsi lainnya. Gen HSP70 berhasil diamplifikasi dari genom S. Typhi dengan reaksi polimerisasi DNA (PCR) menggunakan pasangan primer spesifik HSP70. Hasil elektroforesis menunjukkan bahwa produk amplifikasi tersebut berukuran 1900 pasang basa.Produk PCR dimurnikan sebelum urutan nukleotidanya ditentukan melalui sekuensing. Analisis hasil sekuensing menunjukkan produk PCR tersebut memiliki homologi sebesar 99% dengan dnaK (gen HSP70) S.enterica serovar Typhi strain CT18 yang terdapat pada gene database NCBI.
