Judul: Pengaruh Pendidikan dan Kesehatan terhadap Ketimpangan Pendapatan di Indonesia
Abstrak: Ketimpangan pendapatan masih menjadi permasalahan di Indonesia. Faktor yang memengaruhi ketimpangan pendapatan adalah perbedaan produktivitas dalam masyarakat serta fasilitas pendidikan dan kesehatan tidak memadai. Pendidikan dan kesehatan merupakan faktor penting bagi sumberdaya manusia yang memiliki peranan dalam meningkatkan produktivitas untuk meningkatkan kualitas hidup masyarakat. Tujuan dari penelitian ini adalah mendeskripsikan kondisi ketimpangan pendapatan, pendidikan dan kesehatan serta menganalisis faktor dari pendidikan dan kesehatan yang memiliki pengaruh terhadap ketimpangan pendapatan di Indonesia. Penelitian ini menggunakan analisis data panel dengan model Fixed Effect Model (FEM) dan analisis deskriptif. Hasil dari penelitian ini menunjukkan bahwa variabel rata-rata lama sekolah, tingkat pengangguran terbuka dan anggaran kesehatan berpengaruh negatif signifikan terhadap ketimpangan pendapatan di Indonesia. Variabel angka harapan hidup berpengaruh positif signfikan, PDRB tidak memiliki pengaruh terhadap ketimpangan pendapatan serta anggaran kesehatan berpengaruh negatif signifikan terhadap ketimpangan pendapatan di Indonesia.

Judul: Analisis Peran Pendidikan Dalam Mengatasi Ketimpangan Distribusi Pendapatan Indonesia
Abstrak: Income inequality is one of the major development problem that can be solved through development of human resources. It was done by improving the quality of human capital through education. This study aims to explain the income inequality and the development of education in Indonesia and also to analize the role of education towards the reduction of income inequality by using panel data method. The data of this study includes 33 provinces in Indonesia during the years 2006 until 2011 is using variables : gini index, average length of school, the number of dropouts by level of education, GDP per capita, the ratio of government expenditure from education sector, and labor productivity. This study finds that school enrollment rates, average length of schools, the number of school dropouts in senior and junior high school, and GDP per capita have positive effect whereas other variables have negative effect with income inequality. The government needs to create the educational curriculum that can improve the skills thus economic independence and social welfare can be increased.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
