Poor security makes the house a target for theft. Home security currently used still uses conventional methods. E-KTP (Electronic Identity Card) provided by the government to every citizen has a technology in which there is an RFID chip that can be used as a substitute for conventional door locks. In order for the e-KTP to be able to access the home door, an application needs to be made that can be used on android smartphone. The application makes it easy for homeowners in the E-KTP registration process that can be used to open the door. In addition, the application can send notifications to homeowners if the house is entered by thieves via SMS (Short Message Service) and Call / Call through the SIM800L module which is controlled using an Arduino Nano Microcontroller.","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88385100","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}

Detection of email spam has actually been applied to email services for the public with various methods. But for the use of a limited number of company's e-mail accounts, not all e-mail servers provide spam e-mail detection features. The server administrator must add a separate or modular spam detection feature so that e-mail accounts can be protected from spam e-mail. This study aims to get the best method in the process of detecting spam emails. Some machine learning methods such as Logistic Regression, Decision Tree, and Random Forest are applied and compared results to get the most efficient method of detecting spam e-mail. Efficiency measurements are obtained from the speed of training and testing processes, as well as the accuracy in detecting spam emails. The results obtained in this study indicate that the Random Forest method has the best performance with a test data speed of 0.19 seconds and an accuracy of 98%. This result can be used as a reference for the development of spam detection using other methods.","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"729 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72438888","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}

However, the security of the SMS is questionable because the message sent must pass through a third party frist, namely SMSC (Short Message Service Center), so that message can be tapped or misused. One of the ways to reduce this risk is to encrypt or keep the original message secret by applying the cryptography algorithm. This research is to develop a system that serves to encrypt and decrypt SMS for Android-based smartphone users. The application is created to encrypt dan decrypt SMS using the Java programming language on Android, that is applied to smartphone integrated with Android Studio and used RSA cryptography algorithm. The application can be used to encrypt and decrypt SMS using the RSA algorithm on the Android-based smartphone. This application can send an SMS with a size of 86 characters and using QR Code to exchange the public key.","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85905769","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}

Both methods cannot be used to determine the condition of data integrity at the detection stage of the information security cycle. Message Digest is the essence of a file that has a function as a digital fingerprint to represent data integrity. This study aims to compile digital fingerprints to detect changes that occurred in JPEG / exif documents in information security. The research phase consists of five stages. The first stage, identification of the JPEG / exif document structure conducted using the Boyer-Moore string matching algorithm to find JPEG/exif segments location. The Second stage is segment content acquisition, conducted based on segment location and length obtained. The Third step, computing message digest for each segment using SHA512 hash function. Fourth stage, JPEG / exif document modification experiments to identified affected segments. The fifth stage is selecting and combining the hash value of the segment into the message digest. The obtained result shows the message digest for JPEG/exif documents composed of three hash values. The SOI segment hash value used to detect modifications for JPEG to png conversion and image editing. The APP1 hash value used to detect metadata editing. The SOF0 hash values use to detect modification for image recoloring, cropping and resizing — the combination from three hash values as JPEG/exif’s message digest.","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87337624","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}

It has been said that it’s as perfect and as good as worship. Prayer is one of the obligations for Muslims and must be done both for Mukimin and Musafir. The virtue of prayer in the mosque is the same as the value of 20 degrees of reward compared to prayer elsewhere. With the traffic jam phenomenon that is increasing due to heavy traffic. For someone who is traveling home in the afternoon before maghrib, some people are always confused to do Maghrib prayer because of the lack of information about the nearest mosque. The problem can be solved by finding the shortest path is a problem to find the minimum route from the starting point to the destination point with the shortest route. This research was made to design an application that provides direction to the nearest mosque in the area of Larangan, Tangerang city.
