Judul: Pendekatan Lognormal pada Perhitungan Indeks Daya Beli Sebagai Salah Satu Komponen Indeks Pembangunan Manusia
Abstrak: Lognormal method is an alternative approach that can be used if there is skewness in data. Expenditure per capita, which is used for calculating Purchasing Power Index (PPI) as a component of Human Development Index (HDI), is an example of a data that is skewed to the right. Lognormal transformation that is applied on data that is skewed to the right can be used to improve the symetry of skewed data and overcome non normality problems. In this study, the lognormal approach has been used in the calculation of PPI as an alternative method of Central Bureau of Statistic (CBS). In province of West Java, BPS method obtained an average PPI of 58.920 and HDI of 71.323, while lognormal method obtained an average PPI of 59.240 and HDI of 71.430. The difference between the results that are not too large, indicating that lognormal approach can be used as an alternative for PPI calculation.

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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
