Abstract

School transportation is one of the facilities provided by the school in the process of picking up students. In the process of picking up, taking the optimal route is needed to save costs and time. The purpose of this study is to develop a model School transportation routes using the Clustered Generalized Vehicle Routing Problem (CGVRP ) model and the Dijkstra algorithm to get a more optimal route from the route that has been used. Furthermore, comparing the real distance from the shuttle transportation routes with the distance from the results of this case study using the CGVRP model and the Dijkstra algorithm. From the research results obtained by using the CGVRP model and the Djikstra algorithm which is applied to the case study of shuttle students at Darus Sunnah SDIT We found that our result has shorter distance when compared to the distance of the usual route.. The total distance on the SDIT Darus Sunnah route is 2.746.416 meters and costs Rp. 2.214.288 in a month. While the distance from the proposed route obtained 2.333.616 meters for at Rp. 1.881.478 in a month. Therefore the difference in the distance from the real route and the proposed route is 357.288 meters with a difference in cost of Rp. 332.820, - in a month.

Abstract. One of the methods used to overcome overdispersion in poisson regression model is a bivariate negative binomial regression model also known as BNBR Model. Leprosy is a dangerous infectious disease, because it can cause paralysis. Leprosy is divided into 2 types, namely is a leprosy Pausibasilier(PB) type and leprosy Multibasilier (MB) type. Where PB type leprosy is a dry leprosy and MB type leprosy is a wet leprosy. Analysis of the data used to model the number of PB leprosy and MB leprosy cases and find out what factor influence it in East Java, the writer uses the BNBR models. Parameter estimation of the BNBR model uses to Maximum likelihood estimation (MLE) methods with Newton-Raphson iteration as well as testing the hypothesis using MLRT methods. After regression analysis, the results are obtained that of the 10 predictor variables tested, both in PB leprosy and MB leprosy, there are 3 predictor variables that are not significant in the model, namely are: variable percentage of poor population, variable ratio of population who did not graduated SMA, and variable ratio of health facilities. Abstrak. Salah satu metode yang digunakan untuk mengatasi overdispersi dalam regresi Poisson yakni dengan regresi binomial negatif bivariat atau dikenal juga dengan model regresi BNBR. Penyakit Kusta adalah salah satu penyakit menular yang berbahaya, karena dapat menyebabkan kelumpuhan. Jenis penyakit kusta terbagi menjadi 2, yakni Kusta tipe Pausibasiler (PB) dan tipe Multibasiler.(MB). Dimana kusta tipe PB merupakan Kusta kering, dan kusta tipe MB adalah kusta basah. Analisis data yang digunakan untuk memodelkan besarnya jumlah kasus kusta tipePB dan tipe MB, kemudian untuk mengetahui faktor apa saja yang mempengaruhinya di Jawa Timur, penulis menggunakan model BNBR. Penaksiran parameter model BNBR menggunakan Maximum Likelihood Estimation (MLE) dengan iterasi Newton-Raphson serta melakukan pengujian hipotesis menggunakan metode MLRT. Setelah dilakukan analisis regresi, diperoleh hasil bahwa dari 10 variabel prediktor yang diujikan, baik pada kusta tipe PB maupun tipe MB, terdapat 3 variabel prediktor yang tidak signifikan dalam model, yakni: variabel presentase penduduk miskin, variabel rasio penduduk yang tidak tamat SMA, dan variabel rasio sarana kesehatan.

Abstract

This papper discuss about longitudinal data models of claim counts withexcess-zeros, in which time-dependence of the claim counts is modeled by using acopula function. The copula approach extensively to model the serial dependence ofthe claim counts in car insurance, to model this serial dependence of the claimcounts (between the history and future claims). The maximum likelihood is appliedto estimate the parameters of the discrete copula model. A two-step procedure isproposed to estimate the parameters and predict the claim counts of the next periodusing the estimated parameters.

Abstract

Di Indonesia terdapat banyak peternak unggas sebagai matapencaharian sehingga Indonesia rawan sebagai sumber penyebaran flu burung. Penyebab flu burung adalah virus influensa tipe A dengan subtipe H5N1 yang menyebar antar unggas dan dapat menular pada manusia. Burung liar dan hewan domestik (ternak) menjadi sumber penyebar H5N1. Virus ini dapat menular melalui udara ataupun kontak melalui makanan, minuman, dan sentuhan. Flu burung termasuk jenis penyakit mikroparasitis (jenis penyakit yang disebabkan oleh virus) tetapi ada keterkaitan antara unggas dan manusia sebagai hospes (host). Karena itu model flu burung berbeda dengan model-model flu umumnya. Pada penelitian ini akan ditentukan analisis kualitatif dari model penyebaran flu burung (avian flu) untuk mendapatkan bilangan reproduksi dasar R0, dimana R0 bertujuan mengetahui adanya penyebaran penyakit atau tidak adanya penyebaran penyakit melalui analisis stabilitas dari disease free equilibrium maupun endemic equilibrium.

Abstract

In this article, will discuss definition, examples, algebra properties, and somecharacteristic of self-adjoint operators on Hilbert space. In the Hilbert space there are types ofbounded linear operators such as adjoint operators and self-adjoint operators. To investigatecharacteristic of self-adjoint operator required concepts of Hilbert space, operators on Hilbertspaces, Riesz representation theorem, and adjoint operators on Hilbert space. It then takes athought to investigate the characteristic of self-adjoint operators. Discussion of self-adjointoperators more emphasis on understanding the definition, algebra properties, and characteristic ofself-adjoint operators on Hilbert space. The results obtained are algebra properties of self-adjointoperators such as addition, subtraction, scalar multiplication, and multiplication of self-adjointoperators. In addition, some characteristic associated with self-adjoint operators on Hilbert space.

Abstract

In this paper, two mathematical models are given, those are basic model of tuberculosis transmission and transmission model of tuberculosis with the problem of drug resistance. The problem of drug resistance due to the decient compliance with treatment schedules so causes treatment failure. The basic model of tuberculosis transmission incorporates slow and fast progression, efective chemoprophylaxis and therapeutic treatments. If the basic reproduction ratio R0 less than 1, then the disease-free equilibrium is globally asymptotically stable and if R0 > 1, an endemic equilibrium exists and is locally asymptotically stable. Next, transmission model of tuberculosis with the problem of drug resistance as acompetition between two types of strains of Mycobacterium tuberculosis: those are drug-sensitive strain called the regular TB (strain 1) and drug-resistant strain called the resistant TB (strain 2). If R0s less than 1 and R0r less than 1, then the disease-free equilibrium is globally asymptotically stable. If R0r > 1, an endemic equilibrium where only resistant strain exists. If R0s > 1 and R0s > R0r, endemic equilibrium where both types of strains are present and can spread in a population. Numerical simulation with the certain parameters is given to illustrate stability of equilibrium.
