Although malaria had ever been virtually eradicated from Indonesia but currently malaria is recognized as a serious re-emerging threat to public health. This disease is caused by malaria parasite which is transmitted to human host by Anopheles mosquitoes as main vector. It has been widely observed that saliva of mosquito that transmits disease contains several factors that could enhance pathogen infection. Therefore, it should be possible to control pathogen transmission by vaccinating the host against the molecule(s) in saliva that potentiate the infection. However, immunogenic specific component in mosquitoes vectors of Malaria has not yet been identified so far. The objective of this study are to analyze protein profile of SDS-PAGE and to know the immunogity the protein extract of salivary gland from potential vector of Malaria i.e. An. aconitus We used immunogenic reaction between salivary gland extract of these vectors against pool of human sera which were collected from endemic area. The reaction conducted by the dot-blot analyze. SDS-PAGE studies showed 15 major polypeptide bands of 284, 100, 84, 75, 66, 57, 53, 48, 45, 38, 33, 29, 15, 14, and 11 kDa. The dot-blot studies showed that the protein extract of salivary gland from An. aconitus are immunogenic.

Mathematics as a basic science has objects that are abstract, mathematical aimed at understanding the concept by providing the ability to reason logically, systematically, critical, careful and creative so that if the mathematics are taught using the book will be hard to accept students. Junior high school students in general are still difficulties in learning mathematics in particular on the material loop. Therefore, it needs the development of more interactive learning media and can help students in the learning process, one of them with the help of Software Graphic User Interface (GUI) Matlab. The concept of a circle is presented in the form of Software GUI Matlab so that students can use to understand the concepts of geometry with ease and be more independent, and help teachers to explain the concept of the circle in the learning process. The application of the concept of the circle in Matlab GUI Software is done by constructing a circle 1. Concept definition, 2. Elements of the circle, 3. The corners of the circle, 4. Relationships angle at the center of the circle and the angle of the circle, and 5. Nature tangent to the circle . Data construction concept of one to five are arranged in Matlab GUI program to produce instructional media in the form of software.

SAE (Small Area Estimation) is often used by researchers, especially statisticians to estimate parameters of a subpopulation which has a small sample size. Empirical Best Linear Unbiased Prediction (EBLUP) is one of the indirect estimation methods in Small Area Estimation. The presence of outliers in the data can not guarantee that these methods yield precise predictions . Robust regression is one approach that is used in the model Small Area Estimation. Robust approach in estimating such a small area known as the Robust Small Area Estimation. Robust Small Area Estimation divided into several approaches. It calls Maximum Likelihood and M- Estimation. From the result, Robust Small Area Estimation with M-Estimation has the smallest RMSE than others. The value is 1473.7 (with outliers) and 1279.6 (without outlier). In addition the research also indicated that REBLUP with M-Estimation more robust to outliers. It causes the RMSE value with EBLUP has five times to be large with only one outlier are included in the data analysis. As for the REBLUP method is relatively more stable RMSE results.

SCMV (Sugarcane Mosaik Virus) is sugarcane crop disease resulting in chlorosis in leaves with the formation of the colors yellow and green intermittents. Based on survey information obtained that the air observation of all varieties of sugarcane was already stricken with the virus SCMV. Even the most formidable attack is on PS881 varieties with the intensity of the attacks reached 80%, so that it is estimated will lose up to 40% of the harvest. The sugarcane is virus free can be obtained via organogenesis in tissue culture method directly on the apical meristem, somatic embryogenesis at, and also with the addition of khemoterapeutan (acyclovir).The workings of the khemoterapi materials are the chemotherapi will interfere with replication and synthesis of genetic material of the virus but also cause the same effect against the mechanism of synthesis of nuklet acid on plants hosts. This research aims to find the best concentration and exposure time the most good in eliminating viruses SCMV in the apical bud culture of sugarcane PS881, using the antiviral acyclovir in conditions of invitro, so that the resulting plant will be virus free. The methods used to detect the presence of the virus by using the two ways, the first is by serology test through the protein content of the virus / checking nucleic acid virus with ELISA and the second is by RT-PCR. The results of the analysis showed that the interaction between the concentration of chemotherapy and exposure time produces the best treatment in eliminating the virus was . treatment with acyclovirc oncentration of 20 ppm and exposure time of 5 weeks.
