Abstract

AbstractDengue fever is one of the most infectious diseases in the world, according to data issued by the World Health Organization in 2014. It is responsible for a huge number of deaths each year around the world, particularly in tropical nations. The dengue virus (DENV) causes dengue fever, which is spread by the female Aedes aegypti mosquito. We provide a mathematical model of dengue fever transmission through hospitalization with optimal management in this paper. Before being simulated in MATLAB, this optimum control problem is numerically resolved. Vaccination, pesticide use, and prevention are all examples of optimal control in this study. The simulation results demonstrate that dengue infection can be considerably reduced by vaccination, pesticide use, and prevention.Keywords: Dengue fever; Mathematical modelling; Optimal control. AbstrakDemam berdarah adalah salah satu penyakit paling menular di dunia, menurut data yang dikeluarkan oleh Organisasi Kesehatan Dunia pada tahun 2014.

Abstract

One of the demand of teacher performance assessment is that teacher must be active in improving his competence by participating in various kinds of training. However, this policy ultimately triggers teachers not to focus on improving their own quality, but only to focus on certificate quantities. Thus, it can be concluded that the increase in the number of certificates collected is not in line with the expected increase in competency. Given this problem, the Teacher Working Community (TWC) considers it necessary to improve the quality of teacher performance through training activities to become training providers. So in this case, the increase in the number of certificates collected by teachers will be proportional to the competencies they possess. The stages of implementing activities begin with socialization, followed by training, then mentoring and evaluation and the program sustainability stage. The result of holding this training was that the percentage of understanding of the participants was 72% which was categorized as Good. Apart from that, the response from the participants regarding the holding of this training was very good. The sustainability of this training program is to continue the training program for training organizers in other TWC clusters with a wider network scope.

Abstract

This research was conducted on grade X students of a public senior high school in Karangbinangun, Lamongan, Indonesia, on opportunity material by applying Problem-Based Learning (PBL) model. This study aims to determine the effect of the PBL model on students' numeracy ability in solving Asesmen Kompetensi Minimum (AKM) problems on opportunity material. This research is quantitative research using a nonequivalent control group design. The sampling technique used in this study was purposive sampling. Data collection techniques in this study used test instruments, whereas the validity, reliability, differentiating power, and difficulty index have been explained. The data analysis techniques used independent sample t-test and N-gain test. The results showed that applying the PBL model could improve the numeracy ability of students in solving AKM problems on opportunity material. This is evidenced by the difference in the average post-test score obtained by students in the experimental class (88) and in the control class (84). Based on the calculation of the average pretest and post-test in both classes, the percentage of numeracy ability of students in the experimental class was 55.62%, while the percentage of numeracy ability of students in the control class was 51.73%. The calculation of the independent sample t-test also shows significance in the value of sig. (2-tailed) less than 0.05 (0.000 < 0.05). Therefore, the PBL model affects students' numeracy abilities.
