Mathematics is one of the most important sciences in life, this can be seen from mathematics lessons that have even been learned since elementary school and even kindergarten. But learning mathematics is not always easy. Based on observations in the field, there are still many teachers in schools providing a less innovative learning, learning strategies that are still monotonous and learning methods that are less interesting.Based on data from the UN results in 2019 obtained from the Ministry of Education and Culture shows that NTT is one of 12 provinces where the average UN score is below the national average. Because mathematics is one of the UNBK subjects but occupies the lowest place of other subjects, the authors consider mathematics to be the center of attention, especially in the NTT region especially Kefamenanu. Therefore, the writer applies the sudoku game-assisted learning method to improve the understanding of the students of Warta Bakti Kefamenanu. The researcher compared the pre-test and post-test scores which gave the result that the scores were lower than the post-test scores. This confirms that students' understanding after learning by using the Sudoku game gives significant results.

[Bahasa]: Salah satu metode pembelajaran yang cocok digunakan untuk operasi perkalian adalah metode jarimatika. Metode ini diberikan kepada siswa SD di Kefamenanu mengingat berdasarkan data Badan Pusat Statistik (BPS), Kefamenanu telah memiliki empat perguruan tinggi namun masih banyak siswa yang belum memiliki kemampuan berhitung cepat. Kelebihan metode jarimatika adalah tidak memerlukan alat peraga dan hafalan karena perhitungan dilakukan dengan memanfaatkan jari tangan sehingga diharapkan operasi hitung perkalian dapat lebih mudah dipahami, menyenangkan, dan tidak membebani memori otak siswa. Tujuan kegiatan pengabdian ini adalah untuk meningkatkan kemampuan berhitung siswa sekolah dasar. Kegiatan ini dilaksanakan di SDN Neonbat Kefamenanu, Nusa Tenggara Timur (NTT) dengan subyek pengabdian seluruh siswa kelas V yang berjumlah 60 orang. Pengabdian dilaksanakan dalam bentuk workshop yang dibagi menjadi 2 hari. Pelaksanaan hari pertama fokus pada review kemampuan dasar siswa yang meliputi perkalian 1-5 dan dilanjutkan dengan perkenalan teknik berhitung cepat dengan jarimatika untuk perkalian 6-10 dan 11-15. Pengabdian dilanjutkan pada hari kedua yaitu review materi pada hari sebelumnya dan penyampaian teknik berhitung cepat untuk kelompok 16-20 yang diakhiri dengan pemberian latihan. Kegiatan pengabdian tidak hanya berhenti pada workshop tetapi dilanjutkan dengan pendampingan terhadap siswa yang dipilih sebanyak 20 orang. Kegiatan pendampingan ini memberikan dampak positif terhadap hasil belajar yang diperoleh siswa. Hal ini dapat dilihat dari peningkatan nilai rata-rata pada pre-testsebesar 55,84 dan pada post test sebesar 75. Kata Kunci: berhitung cepat; metode jarimatika; perkalian; sekolah dasar [English]: One of the appropriate methods to learn multiplication is Jarimatika. It was given to elementary school students in Kefamenanu which, based on data from statistical central agency (BPS), has four colleges but there are still many students who do not have rapid counting skills. The advantage of this method is not requiring learning tools and memorization because calculations are done by utilizing the fingers so that the expected counting operation of multiplication can be more easily understood, enjoyable, and does not overload students’ memory. The purpose of this community service program was to improve the counting skills of elementary school students. It was held at SDN Neonbat Kefamenanu, East Nusa Tenggara (NTT) involving 60 5th-grade students. The program was carried out in two-day workshop. The first day focused on the review of students ' basic ability which includes multiplication 1-5 and continued with the introduction of quick counting techniques with Jarimatika for multiplication 6-10 and 11-15. The second day was to review the previous day and introduce the rapid counting technique for multiplication 16-20. This program did not only end with the workshop but also continued with the assistance of 20 selected students. This assistance provided a positive impact on the results students get which can be seen from the increasing average score: 55,84 in the pre-test then increased to 75 in the post-test. Keywords: fast counting; jarimatika method; multiplication; elementary school

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. Tuberculosis that fails treatment will develop into multidrug-resistant tuberculosis. Research on the TB epidemic continues, particularly in the field of applied mathematics with modeling. In this study, we analyzed a suitable strategy in controlling the development of susceptible individuals to active tuberculosis and even multidrug-resistant tuberculosis. In this work, local stability analysis was carried out around the equilibrium point. Also, to see the most influential parameters in the epidemic, a sensitivity analysis was performed on basic reproductive factors. Besides, the final work was to do numerical simulations with some cases, so that the model could describe the disease's phenomena and characteristics.

Dengue is one of the infectious diseases transmitted to humans by the bite of Aedes aegypti or Aedes albopictus mosquitoes. Dengue virus infections include dengue fever, dengue hemorrhagic fever and Dengue Shock Syndrome (DSS). The dengue virus has four types of serotypes: DEN_1, DEN_2, DEN_3, DEN_4. In the model, will be studied the dynamics of the spread of dengue hemorrhagic disease type SEIR. From the model then fixed point will be determined, then analyzed the stability of each fixed point by considering the basic reproduction number (R_0 ). The results showed that for fixed point without disease the condition would be stable when R_0<1, while the fixed point of endemic would be stable for condition whenR_0>1.

This research discusses the numerical solution of the infiltration problem of the periodic flat channel and is solved using the Dual Reciprocity Boundary Element Method (DRBEM) numerical method with polynomial radial basis functions. DRBEM is a development of the Boundary Element Method, used for PDP solutions in the fields of mathematical physics and engineering. DRBEM has an important role in obtaining a solution to the Helmholtz equation by describing the reciprocal relation between the fundamental solution of the Laplace equation and the solution to be sought. Furthermore, the term containing the double integral in the calculation is approximated by the radial basis function, in order to obtain an equation containing only the boundary integral. The objective of the obtained numerical solution is then compared with the analytical solution obtained by Batu, in order to obtain an accurate solution of the polynomial radial base function for solving the infiltration problem. The mathematical models used in the infiltration problem are the Richards equations, Kirchoff transformation and the dimensionless variables for obtaining the modified Helmholtz equation. The results of the calculation of the numerical solution have shown that the DRBEM with the radial polynomial base function for the number of boundary elements resulting from the discretization and the number of interior collocation points at (N = 200, L = 400) and (N = 225, L = 400) obtained the approximate value ( error) from the six points in the region, indicating that the greater the value of N, the smaller the error. So that for FBR, and the one with the smallest error is , it means that it is close to the FBR used by Batu, is .. Thus, it is concluded that the more discrete line segments result in the region boundary, the numerical solution will approximate the analytical solution. Keywords: Infiltration, modified Helmholtz equation, FBR, DRBEM.

Penyakit Demam Berdarah Dengue (DBD) adalah salah satu penyakit yang masih berkembang dalam kehidupan masyarakat. Penyebab utama penyebaran penyakit DBD adalah gigitan dari nyamuk Aedes Aegypti, bisa juga disebabkan oleh nyamuk Aedes Albopictus. Selama ini sudah banyak dilakukan pencegahan tetapi masih ada yang teridentifikasi terinfeksi penyakit DBD. Hal ini disebabkan oleh iklim, di antaranya suhu, kelembaban udara dan curah hujan. Penyakit DBD ditunjukkan melalui gejala flu yang menyerang bayi, anak-anak dan orang dewasa dan bisa berakibat fatal. Gejala ini berlangsung selama 2 sampai 7 hari. Tujuan dari penelitian ini adalah merekontruksi model penyebaran penyakit DBD di Kota Kefamenanu berdasarkan data yang di ambil dari RSUD Kota Kefamenanu pada tahun 2017 sampai tahun 2019, dari model kemudian dilakukan pencarian titik tetap, bilangan reproduksi dasar, analisis kestabilan terhadap titik tetap dan simulasi. Hasil simulasi menunjukkan bahwa semakin meningkatnya laju nyamuk terinfeksi (????????) akan menyebabkan bilangan ℛ0 semakin meningkat sehingga laju penyebaran penyakit dalam populasi akan semakin meningkat. Oleh karena itu laju nyamuk infeksi (????????) perlu dikurangi agar penyebaran penyakit DBD memiliki peluang yang sangat kecil.

Demam Berdarah Dengue (DBD) menjadi salah satu masalah kesehatan masyarakat di Indonesia yang masih membutuhkan penanganan hingga saat ini. Salah satunya yakni memberantas larva nyamuk DBD memakai larvasida. Penelitian ini membahas mengenai model penyebaran penyakit DBD tipe SIR, kelompok populasi manusia (host) dipilah menjadi tiga kelas, yaitu Susceptible, Infected, dan Recovered, sedangkan populasi nyamuk (vektor) juga dalam tiga kelas, yakni ASI (Aquatic, Susceptible, dan Infected). Selanjutnya dari model ditentukan titik kesetimbangan, bilangan reproduksi dasar, analisis kestabilan terhadap titik kesetimbangan bebas penyakit dan simulasi. Hasil analisis menunjukkan bahwa pada kondisi ℛ0 < 1 titik kesetimbangan tanpa penyakit stabil asimtotik. Hasil simulasi pengaruh penggunaan larvasida terhadap penyebaran penyakit DBD juga menunjukkan bahwa semakin meningkatnya jumlah kematian larva karena pengaruh penggunaan larvasida menyebabkan bilangan reproduksi dasar semakin menurun bahkan sangat kecil sehingga hal ini dapat membantu menekan laju penyebaran penyakit DBD tersebut dalam populasi.
