Hemodialysis will affect stress levels and sleep quality in chronic kidney failure patients. The longer a patient with chronic kidney failure undergoes hemodialysis therapy, the patient's stress level and sleep quality will worsen. The study aimed to analyze the relationship between the term hemodialysis and the stress level and sleep quality of chronic kidney failure patients at Tk.III Slamet Riyadi Hospital, Surakarta. The research adopted a quantitative descriptive analytical design with a cross-sectional approach. The sampling technique used total sampling with 57 respondents. Data collection methods utilized the Depression Anxiety Stress Scale (DASS-42) and Pittsburgh Sleep Quality Index (PSQI) questionnaires. The statistical test operated the gamma test. The results revealed the relationship between the term hemodialysis and stress levels and sleep quality with a p-value of 0.009 and 0.006. It inferred a relationship between the hemodialysis span, stress levels, and sleep quality. The correlation value between variables is 0.431 and 0.410. The longer the hemodialysis, the higher the stress level and the worse the patient's sleep quality (one blank single space line, 9 point font)

Penelitian ini bertujuan menaksir parameter model ARCH menggunakan Metode Bayes kemudian akan dibandingkan dengan metode Maksimum Likelihood. Pada metode Bayes distribusi prior digabungkan dengan fungsi Likelihood untuk memperoleh distribusi posterior, yang akan menjadi dasar dalam inferensi. Pemilihan prior yang berbeda akan menghasilkan inferensi yang berbeda pula. Distribusi prior yang digunakan dalam penelitian ini adalah prior berdistribusi eksponensial. Setelah distribusi posterior diperoleh, dilakukan simulasi Markov Chain Monte Carlo dengan menggunakan Algoritma Metropolist-Hasting. Dari hasil simulasi MCMC tersebut diperoleh estimator model ARCH menggunakan metode Bayes dan kemudian dibandingkan dengan estimator model ARCH menggunakan metode Maksimum Likelihood. Berdasarkan penelitian ini diketahui bahwa dengan menggunakan data yang sama nilai mean residual dan standard error menggunakan metode Bayes lebih kecil dibandingkan metode Maksimum Likelihood. Hasil mean residual dan standard error menggunakan metode Bayes adalah 0,4372 dan 0,0272. Sedangkan Mean residual dan standard error menggunakan metode Maksimum Likelihood adalah 0,9166 dan 0,0456. Dari hasil tersebut dapat dilihat bahwa estimasi parameter menggunakan metode Bayes baik digunakan pada model ini.

K-Means is a clustering algorithm that groups data based on similarities between data. Some of the problems that arise from this algorithm are when determining the center point of the cluster randomly. This will certainly affect the final result of a clustering process. To anticipate the poor accuracy value, a process is needed to determine the initial centroid in the initialization process. The second problem is when calculating the Euclidean distance on the distance between data. However, this method only gives the same impact on each data attribute. From some of these problems, this study proposes the Rank Order Centroid (ROC) method for initializing the cluster center point and using the Braycurtis distance method to calculate the distance between data. With the experiment K=2 to K=10, the results obtained in this study are the proposed method obtains an iteration reduction of 6.6% on the Student Performance Exams dataset and 19.3% on the Body Fat Prediction dataset. However, there was an increase in iterations on the Heart Failure dataset by 24.2%. In testing the cluster results using the Silhouette Coefficient, this method shows an increase in the evaluation value of 5.9% in the Student Performance Exams dataset. However, the evaluation value decreased by 8.3% in the Body Fat Prediction dataset and 3.3% in the Heart Failure dataset.

The use of electric vehicles recently is an alternative way to lower pollutants and the emissions of carbon dioxide resulting from the usage of motor vehicle fuel oil. The limited battery capacity of this electric vehicle is a problem for its users. Vehicle routing problem (VRP) is a problem of integer programming and combinatorial optimization that is frequently used in planning and decision-making processes. One application of this issue is to find the best path for delivering items from a corporation to customers. VRP problems are frequently utilized in order to reduce internal expenditure. Model optimization in this paper uses two rehcarging options, recharging and swapping battery. The purpose of this paper is to present a VRP optimization model for electric vehicle routing problems to find the best route option that minimizes the total of the fees for fixed vehicles, transit, charging, battery changing, and waiting.

This article discusses the model of inventory with greater demand at the beginning which allows shortages. During the shortage period, it is assumed that there is a backlogged demand, and the remainder is considered lost sales. This research is completed by using the deterministic inventory model method, namely the EOQ model. The result of using the EOQ method is to determine the inventory lot size and length, with the goal of minimizing the total cost of inventory and generating maximum profits related to the inventory model. An numerical example is given to show the use of this model.

Migration of rural communities to cities increases logistics activities in urban areas to meet customer needs because there is a close relationship between economic expansion and usage. Daily fluctuating demand for logistics, uncertain driving times and insufficient parking spaces are some of the factors that link the crisis in urban logistics in urban areas, which directly affects operational costs, the environment and its success or failure. The related steps of modeling optimization have a major impact in making complex transportation and logistics systems competitive with each other. This paper proposes a model optimization to solve transportation problems mathematically. The integer programming model would be suitable for the problems that have been described. the author uses direct search to complete the model.

A Nonparametric regression with a truncated biresponse spline approach is a good method in solving the problem of unknown shape of the regression curve. Truncated splines provide high flexibility in estimating curves that have data patterns that tend to change at certain intervals and do not require classic assumption tests. The purpose of this study was to obtain the best biresponse truncated spline regression model for North Sumatra's inflation and GRDP. This study uses qualitative methods and uses secondary data obtained from the Central Bureau of Statistics of North Sumatra. Selection of the best model is determined based on the optimal knot point using the minimum GCV value criteria. The research results obtained are the best spline model with 3 knot points with an MSE value of 1.6028 and a minimum GCV value of 0.0452. The value of response 1 is 14.64% and response 2 is 61.85%. This means that the ability of the predictor variable to explain the variance of the response variable is 14.64% and the remaining 61.85% is influenced by other factors.
