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

Judul: Analisis Kinerja Waktu Pada Proyek Pembangunan Gedung Perpustakaan Dengan Menggunakan Metode Jalur Kritis (Studi Kasus : Proyek X Oleh PT. ABC)
Abstrak: Construction in Indonesia is still continuing to meet a range of facilities required. In the implementation of a project, there are some aspects that should be concern, such as limited time, cost, and good in quality and safety. Limited availability of time on the project development is a challenge that must be resolved by implementing the development. A good and reliable project management is the main key of development project can be completed according to plan. Performances of a project, including time, cost, and also quality and safety performance. A construction project must be able to achieve a good performance. Therefore, it takes an instrument and method to analyze the performance of the project during the project underway, especially the time performance. This study will be focused in analyzing project management that is time performance at library construction Project X by PT. ABC. This study will be comparing library development project which use Barchart and S curve with Critical Path Method, by using Microsoft Project 2010 software to analyze time performance every week during construction. Analyze of this study shows that the library building has already been built corresponding plan and has appropriate with critical path method. There is some discrepancies identified comparing with plan schedule, it shows that some works has done behind schedule, but overall the construction can be finished on schedule. Realization of the cumulative weekly weight always exceeds cumulative weekly weight plan, with the smallest value at first week (+0.4888%) and the largest value at thirteenth week (+10.4538%). But, there are several weeks of work that realization of the cumulative weekly weight does not reach the plan, at sixth week (-2.3986%), seventh week (-1.3036%), and the tenth week (-1.7140%). At last the project management on time performance during the library construction Project X by PT. ABC shows a good performance.

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. ...
