The decrease of rice-field area is one of causes of decreasing rice production in Indonesia. Physical development in many sectors has been converting rice field area into others such as industry, high ways, settlement and other agricultural areas. Because of limited possibility to extent rice field area, one of the efforts of increasing rice production is to implement intensification program.
Rice paddy intensification program relates to "green revolution". Reaching success in 1984 indicated ...

Perolehan TiO2 dari pasir besi melalui pelindian asam klorida (HCl) telah dilakukan. Pasir besi menjadi salah satu komoditas pertambangan yang turut memegang peranan penting dalam menggerakkan perekonomian Indonesia. TiO2 yang dapat diperoleh dari ilmenite (FeTiO3) pada pasir besi mampu memberikan nilai tambah pasir besi. Pada penelitian ini, proses diawali dengan menghaluskan pasir besi sehingga didapatkan ukuran sebesar 325 mesh yang kemudian pasir besi diseparasi menggunakan magnet NdFeB dan komposit NdFeB untuk memisahkan ilmenite dari senyawa ...

Extended Elastic Impedance method is one of the methods in reservoir characterization, which is used to identify lithology and fluids content. This method is an extension of Elastic Impedance method by changing Sin²θ in Zoeppritz equation with tan χ to get scaled reflectivity equation. χ is angle range between -90° up to 90°. By using proper angle (χ), we can calculate the reflectivity that associates with the log parameter (Gamma Ray, Porosity, Lamda-Rho and Mhu-Rho). ...
