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: Analisis Faktor-Faktor yang Memengaruhi Pertumbuhan Total Factor Productivity (TFP) Sektor Pertanian di Indonesia
Abstrak: The agricultural sector is a sector which is crucial and has an important role for people life. Enhancement in agricultural productivity is the focus of the current Government. Previous research shows that the growth of agricultural output was not only influenced by the capital and labor but there is another factor called Total Factor Productivity (TFP). This research focuses on the factors that affect TFP growth of the agricultural sector in Indonesia in the period 1980-2011. This research using Cobb-Douglas linearization to calculate TFP value. Error Correction Model (ECM) used to analyze factors that affect agricultural TFP. Independent variables used in this model are irrigation, inflation rate, level of education, agricultural credit, and trade openness, while the dependent variable used is agricultural TFP. The results of this research indicate that the variables that affect agricultural TFP in the short-term are education and level of trade openness. Variables that affect agricultural TFP on long term are the level of education, agricultural credit, and trade openness.

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.
