Judul: Profil Antibodi IgM dan IgG pada Beruk (Macaca nemestrina) setelah Diinfeksi Virus Dengue Serotipe-3 (DEN-3) melalui Rute Subkutan
Abstrak: This study was to compare the immune response in pig-tailed macaques (Macaca nemestrina) induced by the dengue virus serotype-3 (DEN-3) via subcutaneous route. There are 3 groups of animal in the study. Group 1 (n=6) were infected by DEN-3 at low dose level of 104 PFU/ml, group 2 (n=6) were infected by DEN-3 at high dose level of 107-108 PFU/ml, and group 3 (n=4) were infected by PBS; all groups were innoculated by subcutaneous route. The blood samples were collected using venesectio method in femoralis vein on day 0 prior the infection followed by day 1 until day 13 post infection. IgM and IgG antibodies were detected by Indirect Enzym Linked Immunosorbent Assay (ELISA). Dengue virus induced humoral immune respons producing antibodies. The antibody profile analyses showed different by individual animals, but similar in general. The IgM titer started to increase on day 4 or day 5 post infection and reached the peak on day 9 post infection and decline afterward; The IgG titer started to increase on day 7 or 8 post infection. In general the increase of IgM titer started earlier than the IgG and the titer of IgM was higher than the IgG.

Judul: Profil Antibodi IgM dan IgG pada Beruk (Macaca nemestrina) setelah Diinfeksi Virus Dengue Serotipe-3 (DEN-3) melalui Rute Intravena
Abstrak: The aim of this study was to detect IgM and IgG in pig-tailed macaques (Macaca nemestrina) primarily innoculated by Dengue virus serotype-3 (DEN-3) by intravenous route. A total of 84 plasma samples were examined in the study. Plasma samples were taken on day 0 before infection, followed by plasma collections on day 1 through day 13 post infection. The obtained plasma samples were analyzed using indirect ELISA test. The results showed the increasing titer of IgM started on day-3 post infection with its peak occurred on day 11 post infection and started to decline afterward; while the IgG titer started to increase on day 6 or day 7 post infection and continue to increase until the day 13 post infection. These results showed that in a primary infection of DEN-3 byintravenous route, the tendency of IgM titer increase was higher than the IgG titer increase; also shown that the IgM titer increase was occured earlier than IgG. The profile of IgM and IgG antibodies is outlined in this study.

Judul: Penyelesaian Stacker Crane Problem dengan Algoritme Largearcs dan Smallarcs
Abstrak: In graph theory, the Rural Postman Problem (RPP) aims to determine the shortest route with minimum cost, in which only certain edges or arcs are necessarily traversed. One type of RPP is Stacker Crane Problem (SCP) which deals with a mixed graph but only arcs are necessarily traversed. SCP can be solved by using two heuristic algorithms, i.e. Largearcs and Smallarcs algorithms, which include other algorithms in their steps, such as: Dijkstra algorithm to determine shortest route, Hungaria method to determine minimum bipartite matching, Prim algorithm to determine minimum spanning tree, and van Aardenne-Ehrenfest & de-Bruijn algorithm and Fleury algorithm to determine Euler circuits. The shortest Euler circuit resulted from two heuristic algorithms can be used to find a solution of SCP. The application of SCP is illustrated in establishing the minimum distance route of catering delivery.
