Judul: Faktor-faktor yang Memengaruhi Total Factor Productivity Sektor Industri Nonpertanian di Indonesia
Abstrak: Industrial output could be increased through the productivity of factor production. The objective of this research are to analyze the Total Factor Productivity (TFP) and to investigate the factors that affect the TFP non-agricultural industry and each sub-sector (paper, chemicals, non-metal mining, basic metals, metal products). Econometric method is used to calculate TFP by regressing data of input and output from non-agriculture industry as an agregat and as sub-sector to get the Cobb-Douglas production function, and to analyze the factors that affect TFP calculated using Error Correction Model (ECM). The results show the largest average TFP found in industrial subsector of metallic goods while the lowest is at the basic metal industry. The factors that affect non-agricultural industrial TFP in the short term are industrial GDP and industrial domestic investment (PMDN). in the long run is affected by industrial foreign investment (PMA), PMDN, and imports of capital (M).

Judul: Faktor-faktor yang Memengaruhi Total Factor Productivity Industri Pertanian Indonesia Periode 1981-2010
Abstrak: Industry has a big role in Indonesia’s economy as the main driver of development, which it gives the largest contribution to the Gross National Product (GNP). Indonesia is an agrarian country which has a big potency in developing agriculture products because of the abundant resources it has, supporting climate, and fertile soil. This study aims to analyze Total Factor Productivity (TFP) of Indonesia’s agriculture industry through a Cobb-Douglas production function approach and analyze factors influencing it using Error Correction Model (ECM), along with a descriptive method to explain an overview of agriculture industry in Indonesia. Time series data are used for period 1980-2010. The estimation result shows that variables significantly influencing TFP are Gross National Product, domestic investment, export of industry output (X), and investment import (M).

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.
