OPTIMAL CONTROL OF INFLUENZA A DYNAMICS IN THE EMERGENCE OF A TWO STRAIN
Full text linkThis paper examines the influenza spread model by considering subpopulation, vaccination, resistance to analgesic/antipyretic drugs + nasal decongestants. Based on the studied model are determined, non-endemic, endemic stability points and the basic reproduction number. In the model studied, control is given in an effort to prevent contact of individuals infected with influenza and susceptible (u1), and control treatment for infected individuals in an effort to accelerate the recovery of infected individuals (u2). In the numerical simulation, using the control u1 the number of infected individuals subpopulation decreased compared to that without control. The number of individual recovered subpopulations using the u2 control increased more than that without the control
ANALISIS MODEL PROBABILISTIK PUNAHNYA MUTAN PARASIT MALARIA YANG RESISTEN TERHADAP KLOROKUIN PLUS AMODIAKUIN
No full textIn 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
PENINGKATAN PENGETAHUAN PENULISAN BUKU AJAR PADA GURU-GURU SMP
Full text linkThe teacher is the dominant factor in the learning process at school. In the learning process, teachers are required to master the material being taught. Mastery of the material to be taught is an absolute requirement for the teacher, teachers can make textbooks or modules from the subjects being taught to better understand the material taught by a teacher. Making textbooks requires willingness, perseverance, commitment and lots of references. The sample of this research is the teachers of SMP Negeri 4 Jayapura as many as 17 teachers. The research activity was carried out, first the author gave a pre-test instrument to the teachers about the knowledge of textbook writing. Researchers provide material about the knowledge of writing textbooks, how to collect references, via the internet, textbooks, modules and journals. Textbook writing, code of ethics norms for editing teaching materials, Indonesian grammar according to textbook writing standards. The teaching materials were delivered, followed by questions and answers and discussions with activity participants. The activities carried out went well, it could be seen from the enthusiasm and motivation of the participants to take part in the activities. The materials prepared by the activity implementers were 98% complete. Participants in the activity were 17 participants, from the expected 15-20 teachers. After the material is taught, the post-test instrument is the same as the pre-test. Based on the results of the pre-test and post-test, the teacher gained an increase in knowledge about writing teaching materials with an average n-Gain of 0.41 including the medium category.Keywords: teaching materials; teachers; n-Gai
PROBABILISTIK PUNAHNYA MYCOBACTERIUM TUBERCULOSA YANG RESISTEN TERHADAP OBAT ANTI TUBERKULOSIS RESISTENSI PRIMER, RESISTENSI TERHADAP ISONIAZID, DAN TB–MDR DI PUSKESMAS KOTA MEDAN
Full text linkIn this paper, probabilistic models are developed from a dynamical model of tuberculosis transmission based on a Galton-Watson branching and Negative Binomialdistribution generation with weighted probability estimation used to test an extinction model of mycobacterium germ. The values of model parameters were obtained from the medical record data at Puskesmas Kota Medan : 31 tuberculosis patients treated during February-August 2015, with 25 sensitive samples, 3 samples of RI degree, 2 samples of RII degree, and 3 samples of RIII degree. Data analysis using Galton-Watson theorem revealed the extinction point of resistant malaria parasites, that is s = 1. The successful transmission of mycobacterium bacteria is 36 people per year. The extinction probability of mycobacterium bacteria that is resistant to anti-tuberculosis drugs is ϕNB = 1
