Abstrak: In conventional manner, learning process is done in the form of discussion or direct delivery of learning materials in a class or lecture. Programming is not easily applied to a conventional learning process. In this condition, LMS has an important role to improve the process of learning for programming. TOKI LC has been developed to identify the programming in Pascal, C, and C++ languages. However, this system has not been equipped with a programming language that is often used by student majoring in computer science or informatics. Therefore, this research aims to analyze and develop four other programming languages into learning management systems in the field of programming. LMS for programming was analyzed according to the concepts of e-learning, storyboard, and grading model. The system was developed with the prototype model on method of development grader, and then tested. Analysis shows that the system is adopting asynchronous learning with several main functional components, namely portal, baseline LMS features, and LCMS. Development of grader generates the Java programming language as a language with run time performance and memory space usage greater than the other programming languages, namely Pascal, C, C++, Scheme, PHP, and Perl.

Abstrak: The paradigm alteration of learning strategy from teacher centered to student centered encourage the academic community to use e-learning as one of learning methods which is perceived to be student centered. The use of e-learning is expected to motivate the increase quality of learning and teaching material, quality of activity and independence of learners, as well as communication between educators with learners and among learners. E-learning can also be used to overcome the limitation of classroom and time and distance barriers in the implementation of teaching learning activity. Modular Object Oriented Dynamic learning environment (Moodle) is a software package that allows you to create and conduct course/training/internet based education. In this study, the method used is System Development Life Cycle (SDLC) which consist of six main phrases namely planning system, analysis system, design system, implementation system, testing system, and use and maintenance system. The level of understanding of educators and learners towards e-learning is as Communication Tools for 95.2% of educators and 100% learners, Learning Objects for 96.2% of educators and 100% of learners, Management of User Data for 96.2% of educators and 93% , Usability for 86.5% of educators and 86.6% of learner, Adaptation for 58.1% of educators and 71% of learners, technical Aspect for 73.6% of educators and 79% of learners, the Administration for 71.4% of educators and 98.9% of learners, Course Management for 77.1% of educators and 94.9% of learners. The percentage of interest of the learner is 96.7% and 94.3% for educators. This means the learning model developed using Moodle includes to good category.

Judul: Seroprevalence of Chikungunya and The Risk of Transmission Transmitted Among Blood Donors In Sulawesi-Indonesia
Abstrak: Chikungunya (CHIK) is an arthritogenic alphavirus in the Togaviridae family of arboviruses with an enveloped RNA containing a positive single-stranded 11.8 kb genome. Transmission occurs through the bite of infected Aedes mosquitoes, which are commonly found in tropical and temperate regions. Primary vertebrate hosts include monkeys and humans, in whom this virus replicates efficiently (Diallo et al. 1999). Chikungunya virus (CHIKV) is known for causing acute illness, manifesting with fever, rash, and arthralgia known as Chikungunya fever (Horwood dan Buchy 2015). Despite the high number of Chikungunya cases in Indonesia, comprehensive data are lacking in CHIKV seroprevalence. Previous studies reported the median seroprevalence of anti-CHIKV antibodies in all situations 18.5%, ranging from 0.0 – 73.% (Harapan et al., 2019). However, the gap in epidemiological data of CHIKV in many regions of Indonesia including Sulawesi, is noteworthy. The objective of this study was to determine the seroprevalence of CHIKV infection among healthy individuals from North and South Sulawesi using archive samples. Additionally, an asymptomatic course of CHIKV infection and the high pre-symptomatic viral load as 108pfu/mL (Appassakij et al. 2013) suggest that the infection can threaten blood transfusion safety. Evidence of CHIKV infection among blood donors (Simmons et al. 2016) indicates transfusion-transmitted is probable, although it has not been documented (Petersen dan Epstein 2014). Our study also aimed to test the archive blood donor specimens from North Sulawesi for CHIKV IgM and viremia to determine blood safety in endemic areas. Samples were screened for anti-CHIKV IgG antibodies to determine exposure to CHIKV using an in-house IgG ELISA as previously described (Kosasih et al. 2013) with minor modifications. CHIKV IgM, a marker for recent infection and endemicity, was tested in 303 samples randomly selected from IgG-positive samples using a Euroimmun anti-CHIKV IgM ELISA kit (Luebeck, Germany) following the manufacturer’s instructions. CHIKV RNA detection was carried out using one-step-qRT-PCR. The data generated were analyzed with IBM-SPSS v20 (IBM Corporation, USA). Chi-square (χ2) test to determine significant differences between categorical variables, and a p-value less than 0.05 was considered statistically significant. As many as 1092 serum and plasma samples were analyzed, with CHIK IgG seropositivity at 53.48% (584/1092). The results also show a statistically significant difference in the seropositive rates based on gender (58.8% male and 48.5% female) and region (53.9% South Sulawesi versus 48.7% North Sulawesi). Seropositivity increased with age; approximately half of adults between their 40s and 60s had seroconverted. Most of the participants, 304 (27.8%), were between 21-30 years. The age groups with the least participants were those >60 years and <20 years, with 93 participants each (8.5%), followed by the 51–60-years age group with 142 (13.0%) participants. In addition to IgG, the overall anti-CHIKV IgM seropositivity comprised 12.9% (39/303). A Chi-square analysis shows a statistical significance of anti-CHIKV IgM seropositivity based on gender and region with p-values (p=0.047 and p=0.038, respectively). On the contrary, there was no significant difference in anti-CHIK IgM based on age. The age group with the most participants was the 21-30 years with 19.3% (16/83), while those with the least participants were those >60 years. The current study
