Abstract

Premium reserve is a number of funds that need to be raised by insurance company in preparation for the payment of claims when the policyholder dies. One of the simplest methods to calculate premium reserving is the prospective premium reserve modified using Canadian method which is a modification of the prospective method. Calculation in this study is using Indonesian Mortality Table (TMI) 2011 This study aims to determine the premium reserves using the Canadian method of endowment joint life insurance. Joint life insurance participants in this study are limited to 2 people. The calculation of premium reserves in this study using TMI 2011, starting with calculating the value of annuities, net annual premiums, annual premiums modified based on the Canadian method, and premium reserves at the end of the t-year in the endowment joint life insurance.

Abstract

The Box-Jenkins method is one of the time forecasting methods series. This method uses values in the past as the dependent variable and variable independently ignored. The Box-Jenkins method has the advantage of being usable on non-stationary data can be used on all data patterns so that this method can be used to predict the daily use of cellular data. The purpose of the study to find out the model and predict the amount of cellular data daily usage using data from March 10, 2020 to May 29, 2020. Results of the analysis shows the best model for daily use of cellular data is ARIMA (0,1,2). The best model meets the test requirements, namely the parameter significance test and diagnostic checking.

Abstract

In this article, the problem of spreading hoaxes during the corona-19 outbreak is studied using a mathematical model. Currently, we often see a lot of hoaxes that are very unsettling, for example the news that eggs are a corona drug. In addition, there have been denials of funerals for Covid victims in various regions. In this article, the impact of government education and outreach, decisive action against hoax spreaders and ignorance of people who understand the problem of Covid-19 regarding the spread of hoaxes. The model built using 4 compartments, equilibrium point, free hoax spreader, basic reproduction number and sensitivity analysis are discussed in this article. Several numerical simulations are provided to test the theoretical study of the model

Abstract

Internet quota is the number of limits or limits of usage in internet use.To overcome this, it is necessary to forecast the amount of internet quota usage. The purpose of this study is to predict the amount of internet quota usage using the Autoregressive Integrated Moving Average (ARIMA) method. The ARIMA method commonly called the Box-Jenkins method is a method used for short-term forecasting with the assumption that the time series data used must be stationary, meaning that the average variation of the data in question is constant. The bedt model obtained to predict the amount of internet quota usage is the AR (1) or ARIMA (1,0,0) models. From the forecasting results it can be seen that the amount of internet quota usage is increasing every day

Abstract

Given that G is a simple and connected graph with a set of points and sides, that is, denoted and respectively. The labeling –k total of irregular edges of graph G is that each edge has a different weight. The smallest k value contained in the labeling -k total irregular edges is called the irregular strength of the total side of G which is denoted by the test (G). In this paper, the author examines the irregular strength of the total side of the bag graph and the temple graph. The bag graph is denoted by Ts (n) with the test value and the temple graph is denoted by Pu (n) with the test value
