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. Penyakit ini menyebabkan banyak kematian setiap tahun di seluruh dunia, terutama di negara-negara tropis. Virus dengue (DENV) menyebabkan demam berdarah, yang disebarkan oleh nyamuk Aedes aegypti betina. Kami menyediakan model matematis penularan demam berdarah melalui rawat inap dengan penatalaksanaan optimal dalam makalah ini. Masalah kontrol optimal ini diselesaikan secara numerik sebelum disimulasikan di MATLAB. Vaksinasi, penggunaan pestisida, dan pencegahan merupakan contoh pengendalian yang optimal dalam penelitian ini. Hasil simulasi menunjukkan bahwa infeksi dengue dapat dikurangi dengan vaksinasi, penggunaan pestisida, dan pencegahan.Kata Kunci: Demam berdarah; Pemodelan matematika; Kontrol optimal. 2020MSC: 00A71, 92B05.

Tuberculosis (TB) is caused by bacteria (Mycobacterium tuberculosis) that most commonly attacks the lungs. TB is spread from person to person through the air. When people with pulmonary TB cough, sneeze, or spit, they propel TB germs into the air. By inhaling only a small number of these germs, a person can become infected. Tuberculosis is curable and preventable. Prevention that can be done is by providing education about TB and vaccines. While treatment can be done by treating infected individuals. This study examines the TB epidemic model with the application of control, by finding optimal control solutions using the Pontryagin Minimum Principle method. In this study, three control variables were applied, namely education, vaccination and treatment. Numerical calculations were carried out using the Forward Backward Sweep 4th order Runge Kutta method and and then simulated. The results of the numerical simulation of the TB epidemic model show that by implementing control in the form of education, vaccination, and treatment, the population of infected individuals can be reduced.

Gondanglor Sugio Village has great potential to become a tourist village in Lamongan. Some of the tourist attractions in Gondanglor Village are Gondang Reservoir, G-Park, and Pesarean Nyai Dewi Sekardadu. But in reality, the number of tourists in Gondanglor village is decreasing every year. The aim of this research is to analyze the factors for the decline in the number of tourists and provide a policy brief for tourism development in Gondanglor Village. This research is qualitative research with a case study approach. Data obtained using interviews, questionnaires, observations and surveys. The results of the research show that one of the factors in the decline in the number of tourists is the strategy for optimizing the tourism management system which is less than optimal. This is demonstrated by management, planning, implementation of maintenance of tourist destinations, supervision, accessibility to tourist destinations, organization that only involves related agencies, and should be able to involve all stakeholders so that the involvement of all stakeholders in management can be optimal.

Indonesia's economy is influenced by many factors, including the tourism sector. Through this tourism sector, it is possible for many foreign tourists to visit Indonesia. There are so many foreign tourists who come to Indonesia, forecasting is needed to find out the estimates of foreign tourists in the following months based on existing data. The method that used is the Seasonal Autoregressive Integrated Moving Average (SARIMA) method. The foreign touristâ€™s coming to Indonesia through Soekarno Hatta Airport were taken from the center agency on statistics (BPS) Indonesia. Data on the number of foreign tourists who come to Indonesia through Soekarno Hatta Airport is data with a seasonal pattern. The data used is secondary data obtained from Soekarno Hatta Airport for the period January 2010 to June 2015. In this case it is used to predict the value of the data for the next 6 months using the best model is the . Forecasting results show the number of each month increases from the previous year. In July it showed the highest yield of 342536, which was 297878 in the previous year. Forecasting results show the number of each month increases from the previous year.

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.
