Morphological Study for Identification Improvement of Tambra Fish (Tor spp.: Cyprinidae) from Indonesia
Biodiversitas , 2006,
Abstract: The identification improvement among species of Tor was conducted based on fish specimens in Museum Zoology Bogor. Each species represented 8 specimens and measured 22 characters (in mm) used digital caliper. The Canonical variate analysis (discriminant function analysis) was used. The results showed these four species different in morphology, and Tor soro 100% grouping from its congeners. Five characters were selected to separate species. Commonly, population of tambra fish in the world was critical therefore needed conservation.
The Effects of T-2 Toxin on Preimplantion Embryos and Fetuses of Swiss Webster Mice
HAYATI Journal of Biosciences , 2007,
Abstract: T-2 toxin is a toxic and teratogenic mycotoxin produced by Fusarium tricintum which may contaminate cereal, seed, and food. The aim of this research is to find out the effects of T-2 Toxin on preimplantion embryos and fetuses of Swiss Webster mice. Pregnant female of Swiss Webster mice on 0 or 2 day of gestation was injected intraperitoneally with T-2 toxin at doses 0.05 or 0.10 mg/kg body weight (bw) and the dam was observed at 3.5 and 18 days of gestation. At 0 day of gestation, embryos were arrested at one to eight cell and uncompacted morulae stages (P < 0.01) compared to control, in both 0.05 and 0.10 mg/kg bw doses. The cell numbers of late blastocyst at all treated groups were decreased significantly compared to control. At 2 day of gestation, most of embryos were arrested on compacted morulae stage at dose 0.10 mg/kg bw (P < 0.01), the late blastocyst and its cell number were dose-dependently decreased. The live fetuses decreased significantly at all dose of T-2 toxin. No external malformation occurred in the fetuses. Results showed that T-2 toxin given at preimplantation stages inhibited development of preimplantation embryos as indicated by decreased number of live fetuses. Therefore, it was grouped as embryotoxic agent but those dosages did not cause malformation of the external appearance of Swiss Webster mice fetuses.
Methoxyacetic Acid Induced Apoptosis on the Forelimb Bud of Swiss Webster Mice
HAYATI Journal of Biosciences , 2011,
Abstract: Methoxyacetic acid (MAA) causes digit malformations of mice when it was given orally on gestation day 11. Previous observation showed that malformation was caused by cell death. The aims of the research were to determine the types of cell death, first time of cell death and their distribution pattern on forelimb bud of Swiss Webster (SW) mice. Ten mM/kg of body weight (bw) of MAA were administered by gavage to SW mice on gestation day 11. Forelimb bud of mouse embryos of gestation day 11 + 0, 1, 2, 3, 4, 5 hours were processed with paraffin method and were made plantar section. Cell death at plantar section were colored with 4,6-diamino-2-phenylindole hydrochloride (DAPI) and hematoxylin. The result showed, that digit malformations initially by apoptosis mesenchymal cell at proximal of axial mesoderm in around of primary axial artery has done one hour after treatment. Apoptosis at the axial area, the site formation of digital ray III distributed to preaxial area where digits I and II are formed, and to the site formation of digits IV and V. The number of mesenchyme cell of digital rays II, III, and V was decrease by the increasing of gestation day, while digital ray was not formed and finally digits I, II, III, and V were missing. The reduction number of cell of digital ray IV were delayed time to be formed and its small size. Thereby it can be concluded, that MAA induced digit malformations of SW mice started by apoptosis which is occurrence has been increase in area of digital ray formation, so that digital ray can not be formed, but when formed it will not developed.

Abstract: Blumea balsamifera D.C, Croton tiglium L, Metroxylon sagu Rottb,and Fagraea racemosa Jackwere used as traditional anti-fertilty of Dayak people in Central Kalimantan. These study are to find out the potential plant as anti-fertility on Swiss Webster (SW) mice. Extracts of Blumea balsamifera D.C, Croton tiglium L, Metroxylon sagu Rottb andFagraea racemosa Jack were administered by gavage at the dose level of 0.26 mg/kg body weight (bw) to female of SW mice for 8 days to examined of estrous cycle.To determine of anti-fertility were administered by gavage of 0.26 mg/kg bw of plant extract to female SW mice and mated with normal male of SW mice. Estrous cycle were analyses every day for 9 days and reproduction display were examined at 15 days after fertilization. The result showed, that estrous cycle are inhibited on estrus and metestrus phase for all of extract traditional plant. Reproduction display showed decrease in the number of live fetuses, number of corpus luteum and body weight of the dam mice treated. The decrease in the corpus luteum further and fetuses attributes antifertilty effect of extract to inhibited foliculogenesis. Out of four extracts tested, Blumea balsamifera D.C extract seems to be more potent in anti-fertility activities compared with other extract of traditional plant.

Computer Science , 2015,
Abstract: On Board Data Handling (OBDH) has functions to monitor, control, acquire, analyze, take a decision, and execute the command. OBDH should organize the task between sub system. OBDH like a heart which has a vital function. Because the function is seriously important therefore designing and implementing the OBDH should be carefully, in order to have a good reliability. Many OBDHs have been made to support the satellite mission using primitive programming. In handling the data from various input, OBDH should always be available to all sub systems, when the tasks are many, it is not easy to program using primitive programming. Sometimes the data become corrupt because the data which come to the OBDH is in the same time. Therefore it is required to have a way to handle the data safely and also easy in programming perspective. In this research, OBDH is programmed using multi tasking programming perspective has been created. The Operating System (OS) has been implemented so that can run the tasks simultaneously. The OS is prepared by configuring the Linux Kernel for the specific processor, creating Root File System (RFS), installing the BusyBox. In order to do the above method, preparing the environment in our machine has been done, they are installing the Cross Tool Chain, U-Boot, GNU-Linux Kernel Source etc. After that, programming using c code with multitasking programming can be implemented. By using above method, it is found that programming is easier and the corruption data because of reentrancy can be minimized. Keywords- Operating System, PC-104, Kernel, C Programming

Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.36080
Abstract: A numerical scheme for a SIS epidemic model with a delay is constructed by applying a nonstandard finite difference (NSFD) method. The dynamics of the obtained discrete system is investigated. First we show that the discrete system has equilibria which are exactly the same as those of continuous model. By studying the distribution of the roots of the characteristics equations related to the linearized system, we can provide the stable regions in the appropriate parameter plane. It is shown that the conditions for those equilibria to be asymptotically stable are consistent with the continuous model for any size of numerical time-step. Furthermore, we also establish the existence of Neimark-Sacker bifurcation (also called Hopf bifurcation for map) which is controlled by the time delay. The analytical results are confirmed by some numerical simulations.

Abstract: A study on drinking water quality produced by drinking water refill depots (AMIU) was done in Jakarta, Tangerang and Bekasi. Analysis unit of the study was drinking water refill depots with the sample number of 38 depots. For every selected depot, laboratory analysis were done for natural water (clean water) and drinking water produced by the depots. The total number of sample were 76 water samples. One of the parameters analyzed was microbiological contents, namey total coli bacterial count and Escherechia coli / fecal coli. For collecting information about the sources and storage of natural waters, drinking water treatment processes, treatment equipment, and so on, the depots operators and drinking water refill association personnel were interviewed as well as the water treatment equipment distributors. Based on the interview, it can be stated that the main principles of the water treatment processes from natural water to become drinking water in the AMIU depots were only filtration and disinfections processes. Natural water sources mostly was mountain spring water (89.5%), originated from Bogor (60.5%). and Sukabumi (26.3%). According to the results of laboratory analysis, it can be stated that the percentages of the natural water samples which were not complying with the standards of total coli bacterial count was 31.6% and that of fecal coli was 28.9%. Whereas for drinking water produced by the depots, the percentages of water samples which were not complying with the total coli bacterial count and fecal coli standards were 28.9% and 18.4% respectively. Additionally, the drinking water treatment processes were not sufficient for natural water with the high contents (around 1.600 MPN/100 ml) of total coli and fecal coli bacterial.
