Abstract

COVID-19 pandemic has disrupted the world's health and economy and has resulted in many deaths since the first case occurred in China at the end of 2019. Moreover, The COVID-19 disease spread throughout the world, including Indonesia on March 2, 2020.  Coronavirus quickly spreads through droplets of phlegm through the throat to the lungs. Researchers in the medical field and the exact science are jointly examined the spread, prevention, and optimal control of COVID-19 disease. Due to the prevention of COVID-19, a vaccine has been found  in early 2021, which at the time, the vaccination process was carried out worldwide against COVID-19. This paper examines the spread model of SVEIR-type COVID-19 by considering the vaccination subpopulation. In this study, control of prevention efforts (  and ) and healing efforts  are given and being analyzed with the fourth-order Runge-Kutta approach. Based on numerical simulations, it can be seen that using the controls    and  can reduce the number of infected individuals in the subpopulation compared to those without control. The  control can increase the number of recovered individual subpopulations.Keywords: COVID-19; SVEIR model; optimal control; treatment; vaccination.

Abstract

In this paper probabilistic models are developed from a model of malaria parasite population dynamics proposed by Macdonald [1] based on Galton-Watson branching and generating Negative Binomial distribution with maximum likelihood estimation, to test a model of malaria parasite extinction. Values of the model parameters are calculated using a samples of patients treated at the Jayapura General Hospital. The response of malaria parasites to chloroquine plus amodiaquine was examined with in- vivo tests. Samples were taken from 40 people, with 17 sensitive samples, 9 samples of degree of RI, 8 samples of degree of RII, and 6 samples of degree RIII. The data sample used in the model must satisfy the Negative Binomial distribution. Model construction approach includes: the basic model, study models, and mathematical calculations. A goodness of fit test was used to test the feasibility of the model. The model was focused on predicting the probability of the extinction of mutant malaria parasites resistant to chloroquine plus amodiaquine in a local population. Data analysis revealed the point of the probability of the extinction of resistant malaria parasites using Galton-Watson theorem is s = 0.8814. The probability of the extinction of malaria parasites resistant to chloroquine plus amodiaquine is φNB =0,8902.Keywords: Probabilistic model, malaria, the point of the extinction of parasites,chloroquine plus amodiaquine.Model probabilistik dalam tulisan ini merupakan pengembangan model dinamika populasi parasit malaria yang dikaji oleh Macdonald [1] berbasiskan pencabangan Galton-Watson dan pembangkit distribusi Binomial Negatif dengan estimasi mak- simum likelihood. Kombinasi model pencabangan Galton-Watson dan pembangkit distribusi Binomial Negatif digunakan untuk mengkaji model peluang punahnya parasit malaria. Untuk menentukan nilai parameter-parameter model digunakan data pasien yang berobat di Rumah Sakit Umum Jayapura. Untuk melihat respon parasit malaria terhadap obat antimalaria, digunakan tes in-vivo. Jumlah sampel dalam penelitian ini sebanyak 40 orang, 17 sampel sensitif, 9 sampel derajat RI, 8 sampel derajat RII, dan 6 sampel derajat RIII. Data sampel yang digunakan pada kajian model harus memenuhi syarat distribusi Binomial Negatif. Kemudian dilakukan pengujian kelayakan model dengan menggunakan goodness of fit test. Kajian model tersebut difokuskan untuk memprediksi besarnya probabilitas punah- nya mutan parasit malaria yang resisten terhadap klorokuin plus amodiakuin. Dari hasil analisis data diperoleh titik punahnya parasit malaria dengan menggunakan teorema Galton-Watson s = 0,8814. Sedangkan peluang punahnya parasit malaria yang resisten terhadap klorokuin plus amodiakuin adalah φN B = 0, 8902.Kata Kunci: Model probabilistik, malaria, titik punahnya parasit, klorokuin plusamodiakuin.

Abstract

Dinamika kebiasaan merokok dalam artikel ini dianalisis dengan pendekatan model epidemiologi. Lingkungan perokok dibagi menjadi empat populasi, yaitu populasi  (Potential) menyatakan populasi dari individu-individu yang tidak merokok, populasi  (Light) menyatakan populasi dari perokok ringan, populasi (Smokers) menyatakan populasi dari perokok berat, populasi  menyatakan populasi dari individu-individu yang berhenti merokok sementara dan populasi  menyatakan populasi dari individu-individu yang berhenti merokok secara permanen. Model  tersebut dimodifikasi kemudian dianalisis titik ekuilibriumnya. Langkah pertama, ditentukan titik ekuilibrium bebas rokok. Langkah kedua, ditentukan titik ekuilibrium kebiasaan merokok. Langkah ketiga, ditentukan the Smoking Generation Number (R0 ) dengan menggunakan next generation matrix yang melibatkan radius spektral. Langkah terakhir, kestabilan lokal setiap titik ekuilibrium pada modelnya dianalisis. Hasil analisis menunjukkan bahwa titik ekuilibrium bebas rokok stabil asimtotik lokal saat nilai the Smoking Generation Number kurang dari satu. Sebaliknya, jika nilai the Smoking Generation Number lebih dari satu dan b1(m+g) lebih dari b2(b1-m), maka titik ekuilibrium perokok ringan stabil asimtotik lokal. Sedangkan titik ekuilibrium perokok berat stabil asimtotik lokal jika nilai the Heavy Smoking Generation Number lebih dari satu. Kemudian dilakukan simulasi numerik menggunakan Software Maple untuk mengecek hasil analisis kestabilan lokal titik ekuilibrium tersebut.

Abstract

For teachers and educators, one self-competency that must be developed is enhancing research and scientific paper dissemination. This study aims to determine the abilities and obstacles experienced by teachers in writing scientific papers. Implementing a sequential research design, this research adopts both quantitative and qualitative analysis.  Twenty-seven teachers contributed as participants and gathered data through questionnaires, which were analyzed quantitatively, and semi-structured interviews which were analyzed qualitatively using thematic analysis. The results showed that SMP Negeri 6 Kota Jayapura teachers still face challenges in writing scientific papers. The scores for each issue are as follows: lack of understanding of publication writing guidelines is the most crucial issue with 24.59%. The second highest issue is the minimal time available to teachers, scoring 19.67%. The third highest issue is low teacher motivation, scoring 11.03%. The fourth highest issues are the lack of information on article writing, the prevalence of scientific paper writing services, and teachers' inability to operate computers, scoring 9.83%. The fifth highest issues are the lack of teacher skills in finding references, non-compliance of teachers' journals with writing guidelines, and limited references needed for writing. In conclusion, the three most dominant factors contributing to insufficient writing ability are the lack of scientific writing knowledge, lack of writing time and administrative demand, and low writing motivation. The research findings offer valuable insight both practically and theoretically. In fostering the related issues, training and ongoing support are crucial for developing and maintaining high standards of scientific writing among educators.
