Judul: Analisis Kinerja Waktu dan Pemodelan 3D Pada Proyek Pembangunan Jembatan Cikujang di Kabupaten Tasikmalaya
Abstrak: Project management is one of important part of the construction activities. By project management, contractor can manage existing resources appropriately. One part of the project management is time performance management, time management can be done using barchart, S-curve, and so on. There are several methods that really help in time management, one of them is the Critical Path Method (CPM). This study was to determine the time performance of a bridge construction project using the critical path method and perform 3D modeling. This research was conducted in the Cikujang bridge construction project in Tasikmalaya District. Based on the comparison of realization schedules and plans schedule, in general the project was running smoothly and completed earlier than planned. However, at week 26th there was a slight delay, this is due to a disturbance at mobilizing material. This delay was solved by additional actions working hours

Abstrak: In general, the construction project has an implementation plan and specific implementation schedule. However, along with the times, the level of difficulty to manage and run the project higher. Construction project management is planning, organizing, directing and controlling resources to achieve short-term goals that have been determined. The research, conducted in March-May 2015 is located in the industrial area of Bukit Indah City, Cikampek, Karawang. Time performance analysis on the development of Astra Honda Motor factory using critical path method is done with the help of Microsoft Project 2013 program. With some additional information that is required, 3D modeling is done based on the Detail Engineering Design data of plant development project Astra Honda Motor. Then the time performance is analyzed using the task manager at Tekla Structure 17 in the form of barchart. Analysis of the S curve construction November to April in the above it can be seen that the resulting zero deviation. Deviation of zero is the desired target by the contractor. As one of the problems that occur include delays in development caused by erratic weather, lack of manpower, and financially.

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. ...
