The objective of this research are (1) to analyze the role of estate crops sector and roads, bridges and ports sector in Lampung Province economic development; (2) to analyze connection and role of investment in roads, bridges and ports sector for estate crops sector; and (3) to analyze role of road infrastructure for the improvement of coffee agribusiness performance in Lampung Province. Analysis tool used for this research are input output table analysis, multiple linear regression analysis, and efficiency analysis using mathematic equation. This research were held in Lampung Province. Input-Output analysis (IO) showed that the roads, bridges and ports sector, coconut sector, and coffee sector, are the key sectors in economic development of Lampung province. Estate crops sector who really need the output of roads, bridges and ports sector is the palm sector, while acting as input provider is rubber sector. Increased length of road has positive effect for coffee production in Lampung Province while improved quality of roads could reduce transportation costs up to 22.501%. Reduction in transport costs can reduce production costs and the price of coffee will be more competitive. In order to increased estate crops production specially coffee in Lampung Province, government should build new roads, encourage the use of high quality seeds, and rejuvenation of unproductive trees.

Judul: Kimiawi imunoglobulin G serta perbedaabbya antara berbagi species hewan
Abstrak: Antibodi adalah molekul protein yang dihasilkan oleh sel plasma sebagai akibat interaksi antara limfosit B peka antigen dengan antigen khusus. Antibodi ini disebut juga imunoglobulin karena molekulnya berbentuk globulin. Jadi imunoglobulin merupakan molekul protein yang membawa akti- vitas antibodi, yaitu sifat kombinasi spesifik dengan zat yang mendatangkan formasi antigen. Diantara kelas imunoglobulin, Ig G adalah yang paling melimpah dalam serum darah. Ig G ini memainkan peran utama dalam mekanisme pertahanan. Ig G merupakan struktur glikoprotein dengan dasar bentuk bangunan diagram tetrapolipeptida yang mengandung 4 ran tai polipeptida dengan 2 rantai berat (H) yang identik dan 2 rantai ringan L) yang identik. Rantai polipeptida ini di bentuk oleh rangkaian asam amino. Tiap rantai berat (H) me ngandung 446 residu asam amino dengam BM (2 x 50.000) Dal ton dan tiap rantai ringan (L) mengandung residu asam amino 213() atau 214 () dengan BM (2 x 25.000) Dalton. Bagian variabel dari rantai berat (VH) mengandung 118 residu asam amino dan bagian variabel rantai ringan (VL) mengandung 108 () atau 109 () residu, sedangkan residu sisanya dari masing-masing rantai adalah bagian konstan (CH dan CL). Adanya perbedaan-perbedaan dalam hal asam amino pada salah satu daerah variabel dapat menyebabkan perbedaan imun respon. ...
