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: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
