Judul: Penguraian model indeks pembangunan manusia menggunakan metode penguraian varians dan penerapannya di wilayah Jawa-Bali
Abstrak: Indeks Pembangunan Manusia (IPM) merupakan sebuah indeks gabungan dari beberapa indikator input yaitu kesehatan, pendidikan, serta standar hidup layak yang dapat digunakan untuk mengukur tingkat kesejahteraan hidup seseorang. Penguraian varians adalah sebuah metode yang merupakan bagian dari metode dasar varians di mana model dari sebuah fungsi diuraikan untuk kemudian dijumlahkan kembali tanpa mengubah nilai dari fungsi itu sendiri. Kajian ini dilakukan untuk menguraikan fungsi IPM yang bersifat non homogen, karena dibangun atas tiga buah indikator yang masing-masing memiliki satuan yang berbeda. Metode dasar varians digunakan untuk melihat seberapa besar pengaruh indikator input terhadap output. Perbandingan nilai IPM hasil penguraian varians sesuai dengan nilai IPM hasil perhitungan UNDP.

Judul: Metode Alternatif untuk Menghitung Indeks Pembangunan Manusia di Indonesia
Abstrak: United Nations Development Programme(UNDP) makea reportthat containthe Human DevelopmentIndex (HDI) andrank every year. HDI calculated from four variables, life expectancy (AHH), literacy rate (AMH), mean years school (MYS), and purchasing power parity (PPP). Multiple criteria decision making (MCDM) can be used in determining the ranking of human development. MCDM is the process of determining the best choice of many alternatives. Several methods can be used to solve MCDM problem are technique for order preference by similarity to ideal solution (TOPSIS) and visekriterijumska optimizacija i kompromisno resenje (VIKOR). The results showed that TOPSIS better than the classical UNDP method in producing consistent correlations between HDI with indicator. While UNDP methodis better than VIKOR. TOPSIS method is much better than VIKOR in a ranking of the Human Development Index which is similar to the results of UNDP method. Human DevelopmentinIndonesiahas ahighgapbutthis gapdecreases.

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.
