Abstract

Penelitian ini bertujuan (1) untuk mendeskripsikan rancang bangun pengembangan multimedia pembelajaran interaktif pada mata pelajaran IPS, (2) untuk mengetahui validitas pengembangan multimedia pembelajaran interaktif pada mata pelajaran IPS, (3) untuk mengetahui efektifitas pengembangan multimedia pembelajaran interaktif pada mata pelajaran IPS. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model ADDIE (analyze, design, development, implementasi, evaluation). Analisis data menggunakan analisis deskriptif kualitatif, kuantitatif dan statistik inferensial. Hasil penelitian ini adalah (1) deskripsi rancangan pengembangan, validitas hasil pengembangan multimedia dan efektivitas hasil pengembangan multimedia pembelajaran interaktif pada mata pelajaran IPS. Rancangan pengembangan media menghasilkan naskah multimedia pembelajaran interaktif mata pelajaran IPS. (2) Kualitas hasil pengembangan media menurut review ahli dan siswa yaitu: (a) ahli isi pembelajaran 90% berada pada kategori sangat baik; (b) ahli desain pembelajaran 86,67% berada pada kategori baik; (c) ahli media pembelajaran 92% berada pada kategori sangat baik; d) uji coba perorangan 92,67% berada pada kategori sangat baik; (e) uji coba kelompok kecil 93,3% berada pada kategori sangat baik; (f) dan  uji  coba  lapangan  94,2%  yang  berada  pada  kategori  sangat baik. (3) Efektivitas hasil pengembangan media multimedia pembelajaran interaktif pada mata pelajaran IPS menunjukkan signifikansi yang diperoleh adalah thitung = 12,72 > ttabel = 2,004. Ini berarti Multimedia Pembelajaran Interaktif pada mata pelajaran IPS efektif dalam meningkatkan hasil belajar siswa.

Abstract

Measurement of concentration of sucrose (C12H22O11) solution using Portable Brix Meter was analized to determine its refractive index using Abbe refractometer. The materials used are sucrose solution with a concentration of 5%, 10%, 15%, 20%, 25%, 30%, 35% and 40%, and samples fruits of pear, watermelon, orange, apple and melon and others. The concentration of sucrose solution is proportional to the refractive index. The increase of concentration of sucrose solution will increase the refractive index. Correlation between the concentration of sucrose solution with refractive index is expressed by the equation Refractive index of sucrose solution can be determined from its concentration. Keywords:  sucrose solution, concentration, refractive index, portable brix meter

Abstract

This article will explore why and what factors led to the decline of the Abbasid dynasty after the first period. This research is motivated by the historical fact that in the second period, the glorious period and the ideal government that had been built by the predecessors gradually degraded until finally this dynasty collapsed. One of the causes is none other than disintegration. This article aims to review several things related to how the consolidation and disintegration of the Abbasid dynasty was? And also the factors causing the disintegration of the Abbasid dynasty? The research findings show that the disintegration of the abbasiyah dynasty (1000-1250) AD was caused by none other than two factors, namely internal factors such as loss of social solidarity, extent of power, competition between institutions. Meanwhile, external factors were caused by, among others, Byzantine attacks, coalition crusades.
