Then, in the dryland farmer is Rp 15 703 442.11/year with loss of wage is Rp 550 235 714.29/year. The changes in agricultural productivity on the wetland farmer is Rp 20 325 200/hectar and the loss of income is Rp 1 623 989.60/ton/hectar. In the dryland farmer, decreasing of productivity value is Rp 16 836 480/hectar and the loss of income is Rp 1 312 288.77/ton/hectar.

Judul: The Effect of Farm Field Conversion Towards The Loss of Paddy Farming Income and The Factors Influencing It. (Case Study at South Bogor Regency)
Abstrak: Kecamatan Bogor Selatan pada saat ini memiliki lahan pertanian yang luas. Seiring dengan meningkatnya aktifitas pembangunan dan pertambahan penduduk, kebutuhan lahan meningkat. Hal ini menyebabkan alih fungsi lahan pertanian. Tujuan penelitian ini adalah: (1) Mengestimasi dampak alih fungsi sawah terhadap pendapatan usahatani padi yang hilang di Kecamatan Bogor Selatan, (2) Menganalisis faktor-faktor yang mempengaruhi terjadinya perubahan penggunaan lahan di Kecamatan Bogor Selatan. Faktor-faktor yang mempengaruhi alih fungsi lahan dianalisis secara mikro menggunakan model regresi logistik. Dampak yang terjadi dianalisis dengan menggunakan rata-rata selisih perbedaan pendapatan sebelum dan sesudah lahan di konversi. Hasil menunjukkan bahwa faktor-faktor yang mempengaruhi alih fungsi lahan pertanian adalah luas lahan, proporsi pendapatan, jarak, dan harga lahan. Rata-rata pengurangan pendapatan petani setelah alih fungsi lahan sebesar Rp 1 023 658/musim., At present, South Bogor Regency has a wide farm field. As the activity of the development and the growth of population increases, the need of farm field increases. This causes the change of farm field function. The aim of this research were (1) to estimate the effect of the change of farm field function towards the loss of paddy farming income in South Bogor Regency, (2) to analyze factors influencing this change in South Bogor Regency. The factors influencing the change were analyzed in micro analysis by using logistic regression model. The occuring effects were analyzed by using the average difference of income before and after the conversion of land.

Judul: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
