Di era digital dimana pertumbuhan teknologi melaju pesat dan dinamis, peserta didik harus didorong untuk mengikuti tren perilaku belajar yang memanfaatkan perangkat teknologi yang lebih dikenal dengan technological pedagogical content knowledge (TPACK). Oleh karena itu, pendidik harus mengambil peran penting dalam menyampaikan pengetahuan melalui pemanfaatan teknologi seluler seperti smartphone. Penelitian ini bertujuan untuk mengembangkan aplikasi pembelajaran interaktif yang memadukan game, kuis, dan video pada materi larutan elektrolit dan nonelektrolit, dan menguji usabilitas penggunaan aplikasi di universitas. Penggunaan aplikasi yang diberi nama E-lite ini tidak hanya mengakomodasi pengetahuan dari konsep yang ditargetkan tetapi juga mencakup permainan, multimedia dan uji kemampuan diri yang memungkinkan peserta didik untuk meningkatkan motivasi belajar mereka dalam mempelajari kimia. Pengukuran kemudahan penggunaan aplikasi dan umpan balik pengguna terhadap aplikasi ini melibatkan 50 orang mahasiswa Program Studi Pendidikan Kimia Universitas Syiah Kuala sebagai responden yang dipilih berdasarkan teknik proportional stratified random sampling. Kepada mahasiswa diberikan angket system usability scale (SUS) yang berisi 10 pertanyaan. Hasil pengujian menunjukkan bahwa skor usabilitas mencapai 85,95%, sedangkan validitas konten memiliki nilai 96,3% dan validitas aplikasi adalah sebesar  83%. Oleh karena itu, aplikasi ini secara umum dinyatakan valid dan dapat digunakan sebagai media pembelajaran untuk konsep larutan elektrolit dan nonelektrolit pada tingkat perguruan tinggi atau universitas.

The case Singkil district in October 2015 in the form of inter-religious clashes that led to the burning of churches and loss of life is the fact that social interaction anatar religious adherents in the district of Gunung Meriah has not gone well. This study focused on the background of conflict, the interaction between religious communities after conflict and efforts to foster religious harmony after a conflict in Aceh Singkil. This study used a qualitative approach by using in-depth interviews, Focus Group Discussion (FGD), and study the documentation as data collection techniques. The results showed that the social conflict between religious communities is part of the social dynamics that occur in the community that stretches the inter-religious relations, but on the other hand can strengthen internal solidarity respective faiths. Forms of social interaction leads to the associative process and found to be also the potential that may lead to forms of dissociative interaction. Other forms of social interaction among religions is mutual cooperation, kinship, mutual silaturrahmi and respect among religions. The search results show that during the Aceh Singkil district government has sought to provide guidance to inter-religious harmony though not maximized. This is evident from the Government's efforts impressed yet to find effective strategies for conflict resolution that is holistic, systemic and regenerative. Then it can be predicted that the events of religious conflicts are still likely to occur in the future, both in the district of Gunung Meriah and elsewhere, especially in the district of Aceh Singkil.
