Most activities become work from home (WFH) so that triggers an increase in online transactions. Online transactions in-volving critical information require an electronic signature (DS), which is an authentication and veriﬁcation tool. A fast and accurate pro-cess of sender legitimacy, authenticity, and anti-disclaimer is a must. The procedures used to prove the authenticity of DS, authenticity of the signer’s identity, and anti-repudiation can be carried out with authentication techniques. The purpose of this study is to propose a DS veriﬁcation with an authentication technique based on system public-key cryptosystems by reversing the role of the private key and public key in the Rivest-Shamir-Adleman cryptographic algorithm. The electronic information attached to the DS will be stored in the message M, using a hash function against M to produce h = H ( M ) . The value of h will be encrypted to be a DS with the private key PR ( d, n ) . The signature is veriﬁed to prove its authenticity by decrypting the DS using the public key PU ( e, n ) , thus obtaining the value of h. The value of h is compared with the value of h (cid:48) which is obtained from the value of the message hash function M of the examined DS. If h = h (cid:48) means the DS is authentic. If the digit size is d > e , the signing time is longer than the time required for veriﬁcation, and vice versa.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48422633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Centrality observation in graphs is suitable for any graph with various kinds of centrality methods to be applied to many ﬁelds. In this study, simple, regular, directed and signed graph are being assessed by Degree, Eigenvector, and Beta Centrality. These three methods are related to each other; therefore, it is interesting to study the relation and the characteristic of each method. According to the result, Degree Centrality which assesses centrality based on vertexs direct links is applicable for every graph in this study. On the other hand, Eigenvector Centrality which asses a vertex centrality with respect to its neighbors centrality, is not applicable for the acyclic directed tree. While Beta Centrality is also advantageous for every graph in this study, the use of parameter β aﬀects centrality scores depending on how the measure is conducted for local or global structure. Beta Centrality is an alternative to observing a vertexs centrality score by considering its direct links centrality, in the acyclic directed tree.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43194401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insurance companies are required to have premium reserves and be able to manage them properly in order to cope with future claims by policyholder. There-fore, it is important for insurance companies to calculate reserves. To calculate reserves, insurance companies use a tool in the form of an application. Based on a survey conducted at 2019 Indonesian Actuaries Summit, there are 23% of insurance companies in Indonesia that still use conventional applications because the price oﬀered to buy the more modern application such as Prophet is quite expensive. Meanwhile, the use of conventional application requires a relatively longer time with a higher probability of error in calculating reserves. Therefore, an application program for calculating insurance reserves is needed that can complete calculations more eﬀectively, cheaply, and easily. This study designed GPV Reserve application using the Python programming lan-guage to calculate reserves for endowment life insurance using the Gross Premium Valuation (GPV) model approach. This application can be a tool for life insurance companies in calculating insurance reserves, es-pecially with endowment life insurance products.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47606497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two kinds of parameter estimation methods, namely classical method and Bayesian method. Bayesian method was a method that combines sample distribution with prior distribution. To get a random sample is to use a simulation. One of the simulation techniques used in Bayesian method is Markov Chain Monte Carlo (MCMC) method, which is a simulation method for generating random variables based on the Markov chain. This study discusses Bayesian method with MCMC using Gibbs Sampling algorithm. MCMC method with Gibbs Sampling algorithm works to build a Markov chain by recursively sampling from full conditional posterior distribution of each parameter. In this study, Bayesian method with MCMC using Gibbs Sampling algorithm was applied to estimate parameters of the Stochastic Volatility to converge. Stochastic volatility is a concept that allows for the fact that asset price volatility varies over time and is not constant. This model applied for predicting stock returns of PT. Indofood CBP Sukses Makmur Tbk. (ICBP.JK). Based on Stochastic Volatility model obtained, prediction results for stock returns are almost close to the actual data. Benefit of this research is that the predicted value obtained can be used as a reference for investors to create an optimal portfolio.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47883862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
