Abstrak: Corn is one of commodities which contribute benefits to food industry as the basic material. Carbohydrate and protein in corn are used widely besides those from the rice since its multifunctions support food productions, feed industries and also as material in biofuel.The production of corn shows improvement. However, the value of import of corn is also on the rise. To handle the necessary processing of corn that have added value. It must be seen to sectors that have great relevance to the corn. The purposes of this research are to analyze the relationship between corn commodity and the economic of Indonesia, to analyze the relation between the role of corns commodity and the other economic sectors, to analyze the effect spreeding of corn commodity in the economic of Indonesia, and also to analyze the effect of output multiplier and income multiplier in the economic of Indonesia. The method that used in the analysis is input-output analysis. Therefore, table of input-output data of Indonesia in 2008 is used through the secondary data provided by Statistic Indonesia. The result of this research shows that corn commodity has a little role to the economic of Indonesia. Corn commodity has more roles to increase the growth of its downstream sector than upstream sector. Corn commodity gives effect to output multiplier and positive income to the other economic sector in Indonesia.

Abstrak: Salah satu komoditas pertanian yang mempunyai posisi cukup strategis dalam kehidupan masyarakat Indonesia adalah komoditas jagung. Bagi masyarakat Indonesia, jagung mempakan sumber karbohidrat kedua setelah beras, bahan baku utama industri pakan ternak, bahan baku industri pangan, yang kebutuhannya setiap tahun tems meningkat, dan komoditas jagung menghasilkan produk tumnan yang eukup luas spektrumnya. Dalam rangka mengkaji perilaku pasar jagung dan produk tumnannya, penelitian ini dilakukan dengan tujuan: (l) menganalisis keragaan pasar jagung dan produk turunannya, (2) menganalisis dampak kebijakan ekonomi dan pembahan faktor eksternal terhadap kineJja pasar jagulIg dan produk tumnannya, dan (3) menganalisis dampak kebijakall ekonomi dan perubahan faktor eksternal terhadap kesejahteraan masyarakat pelaku pasar jagung dan produk tumnannya. Penelitian ini menggunakan data time series tahun 1980-2001 dan dianalisis melalui pendekatan ekonometrika. Model terdiri dari 46 persamaan struktural dan 10 persarnaan identitas. Pendugaan parameter dilakukan dengan metoda 2SLS (Two stage least squares).

Judul: Pembuatan dan pencirian elektrode selektif ion Lu3+ (Lutetium) dengan Ionofor 4- odekanadioilbis-(1-fenil-3-metil-5-pirazolon)
Abstrak: The ion selective electrode (ISE) performance is affected by the type of ionophore used. This research developed an Lu3+ ISE with dodecanedioylbis-(1- phenyl-3-methyl-5-pirazolone) (H2DdBP) as ionophore which has been proved selective in Lu3+ liquid-liquid extraction. The best composition of ISE obtained from this research was 33% PVC, 57% acetophenone, 5% H2DdBP, and 5% oleic acid. Linear measurement was obtained with Nernst factor of 16.57 mV/decade at 10-3−10-7 M concentration range in very acidic situation and response time was 15 to 250 seconds. ISE still could be used at pH 4 and 7, with 5% Nernst factor decrease after 30 days usage. Other ions such as Cu2+, Cd2+, Pb2+, Ni2+, Ca2+, and La3+ did not affect the measurement of ISE.
