Abstract

Wave equation is one of the second order of the linear hyperbolic equation. Telegraph equation as a special case of wave equation has interesting point to investigate in the numerical point of view. In this paper, we consider the numerical methods for one dimensional telegraph equation by using cubic B-spline collocation method. Collocation method is one method to solve the partial differential equation model problem. Cubic spline interpolation is an interpolation to a third order polynomial. This polynomial interpolate four point. B-Spline is one of spline function which related to smoothness of the partition. For every spline function with given order can be written as linear combination of those B-spline. As we known that the result of the numerical technique has difference with the exact result which we called as, so that we have an error. The numerical results are compared with the interpolating scaling function method which investigated by Lakestani and Saray in 2010. This numerical methods compared to exact solution by using RMSE (root mean square error), L2 norm error and L_∞ norm error . The error of the solution showed that with the certain function, the cubic collocation of numerical method can be used as an alternative methods to find the solution of the linear hyperbolic of the PDE. The advantages of this study, we can choose the best model of the numerical method for solving the hyperbolic type of PDE. This cubic B-spline collocation method is more efficiently if the error is relatively small and closes to zero. This accuration verified by test of example 1 and example 2 which applied to the model problem.

Abstract

Nyeri merupakan suatu kondisi yang lebih dari satu sensasi yang disebabkan oleh stimulus tertentu. Intensitas bervariasi dari rasa nyeri ringan hingga nyeri berat, tetapi menurun sejalan dengan proses penyembuhan. Manajemen nyeri pada pasien pasca operasi sangat penting baik terapi farmakologi dan nonfarmakologi. Metode farmakologi yang digunakan sebagai manajemen nyeri adalah pemberian analgesic anti nyeri, yang dibagi menjadi dua kelompok: analgesik dan non-narkotik. Nonfarmakologi menyajikan beberapa bentuk terapi musik dan distraksi. Musik adalah kumpulan bunyi yang ditetapkan untuk menghasilkan ritme atau nyanyian, yang dihasilkan dari alat-alat musik yang dapat menghasilkan ritme. Terapi murottal Qur’an adalah terapi mendengarkan al-qur’an yang merupakan terapi keagamaan dimana seseorang mendengarkan ayat-ayat Al-Qur’an. Penulisan Karya Tulis Ilmiah ini menggunakan metode tinjauan sistematis terhadap literature yang ada, untuk mengevaluasi respon subjektif pasien setelah menerapkan terapi murrotal terhadap penurunan nyeri pasca operasi. Hasil dari penelitian literature review ini  terbukti bahwa terapi murrotal Al-Qur’an efektif untuk menurunkan nyeri terhadap pasien pasca operasi. Terapi murrotal Al-Qur’an dapat menggunakan surah yang terkandung dalam Al-Qur’an dan melakukannya selama 15-20 menit.

Abstract

This research discussed about model of Human Development Index (HDI) in Central Java with spatial regression analysis. and identify variables that give significant influence. First, analyze the influence factors based on result of p-value from t test in multiple linear regression models. Then, made spatial weight matrix with queen continguity method. After that, estimate spatial regression models, namely spatial autoregressive (SAR), Spatial error models (SEM), and spatial autoregive moving average (SARMA) and choose the best model based on minimum AIC value. The results showed that SAR was the best spatial regression model and the significant variables was the gross enrollment rates at senior high schools, the health workers, and the district minimum wages. All of them that give positive influences. The variable that give biggest influence for HDI was the health workers. Full Article

Abstract

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. Banyumas Regency is one of the districts with quite high Tuberculosis cases in Central Java. This study aims to analyze the factors that affect the number of tuberculosis cases in Banyumas Regency using regression analysis of count data. Poisson regression is the simplest count data regression model that has the assumption of equidispersion, that is, the mean value equal to the variance. However, in its application, these assumption is often not fulfilled, for example, there are cases of overdispersion (variance value is greater than the mean). In this study, to overcome the case of overdispersion, an approach was used using Generalized Poisson Regression (GPR) and negative binomial regression. The results showed that the data on the number of tuberculosis cases in Banyumas Regency in 2019 was overdispersion. The data modeling of the number of tuberculosis cases in Banyumas Regency with the negative binomial regression model is better than the GPR model. Meanwhile, the only predictor variable that affects the number of tuberculosis cases in Banyumas Regency is the sex ratio of productive age (15-49 years).

Abstract

Clustering N objects into c clusters can be used to get information about data observation. Among the clustering methods are K-Means (KMC) and Fuzzy C-means (FCM) methods. In the K-means method, objects are members or not members of the cluster, while in the FCM method, objects are included in the cluster based on the degree of membership. This study discusses the implementation of KMC and FCM in the custering of sub-districts in Banyumas Regency based on total of population, the number of health workers and the number of health facilities and infrastructure. The results showed that the KMC and FCM methods produced the same cluster membership. Furthermore, the analysis of clustering based on the number of population, the number of health workers and the number of health facilities and infrastructure (scenario 1) and based on the number of health workers and the number of health facilities and infrastructure which have been corrected by population (scenario 2). The percentage of the variance ratio between clusters to the total variance in scenario 1 is 69% while in scenario 2 it is 85%. Clustering based on scenario 2 is better than scenario 1.

Abstract

Logistic regression (LR) is a model that associates the relationship between category-type response variables with quantitative or quantitative and qualitative predictor variables. The prediction of the LR model is in the form of probability. This research studied logistic regression (LR) models and Classification Trees in the case of ordinal response variable types. The data used in this research from The Central Statistics Agency (BPS). The research variables used are Human Development Index (HDI), gross enrollment rate for high school, percentage of poor people, open unemployment, and percentage of married age <17 years and some of the related predictor variables in Central Java Province in 2018. The HDI data is categorized into three levels, namely very high, high, and moderate. The results of the ordinal LR model show that there are three factors that influence the HDI, they are the gross enrollment rate for high school (GER), the percentage of the poor, and the proportion of women who married at the age of less than 17 years. Comparison of the accuracy LR model and Classification Tree in classification analysis shows that if the training data used is 60%-70% the LR model is better than Classification Tree, while the training data used is more than 70% and less than 86% then the Classification Tree model is better than LR.

Abstract

Data survival merupakan bagian dari time-to-event data.  Data survival adalah data longitudinal dimana subjek dipantau dan diikuti dari awal permulaan hingga hingga subjek tersebut mengalami peristiwa yang diinginkan. Demam Berdarah Dengue (DBD) merupakan penyakit infeksi yang disebabkan oleh virus dengue, yang ditularkan dari nyamuk Aedes Spp.  Penanganan pasien DBD dengan karakteristik yang dimilikinya perlu dikaji agar untuk mendapatkan informasi dan mengambil langkah yang tepat. Salah satu upaya dari sisi pemodelan adalah dengan menganalisis daya taha (survival) pasien DBD.  Penelitian ini bertujuan untuk menganalisis performa model survival parametrik dan semiparametric pada kasus DBD. Metode estimasi Breslow, Efron, dan Exact merupakan pilhan estimasi parameter karena dapat menangani kasus waktu kejadiann kembar (ties). Pemilihan performa model erbaik didasarkan pada Akaike Information Criteria (AIC). Hasil analisis menunjukkan bahwa model terbaik yang diperoleh adalah model semiparametrik Cox PH dengan metode estimasi Exact. Berdasarkan model ini ditemukan bahwa pasien dengan karakteristik berusia lebih muda, kadar hematokrit rendah, kadar hemoglobin tinggi, kadar leukosit rendah , dan suhu badan rendah memiliki laju kesembuhan yang lebih besar dibandingkan dengan pasien dengan karakteristik sebaliknya.
