If the affixed watermark is visible, then its presence can interfere with the appearance of the image and it is possible that the watermark will be cut, discarded, or cropped by parties who are not entitled to do so. In this paper, an application is designed to affix a watermark in the form of an invisible message, or an invisible watermark by using a combination of pixel value indicator and the Most Significant Bit (MSB) method on the image, so that it is not detected visually and the visual appearance of the image is not disturbed. The message is scrambled using a key, then the scrambled bits are hidden in the 5th bit MSB and the 6th bit of the green channel or blue channel, depending on the number of bits 1 owned by the red channel which serves as an indicator. The process of hiding the watermark is carried out in the middle area of the image, so it is difficult to cut to remove it. Applications designed can be used to affix an invisible watermark in the form of messages that are not easily removed on digital images, so that they can protect the copyright of a digital image.","PeriodicalId":384219,"journal":{"name":"METHODIKA: Jurnal Teknik Informatika dan Sistem Informasi","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126765455","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}

To search for data through the website, sometimes the user forgets the address of the website to search for data so that the data sought is difficult to obtain and if finally obtained, it takes a long time to find the data. Therefore a system is built that will facilitate the user in searching data without having to fill in the URL address of the search website, users can choose which websites will be used as a source of data search. Applications that are built using the hash join method where this method alone can be used to join tables containing website data in a database so that the user can display the desired data based on the input entered into the application. The results of the searches obtained are contents that contain texts in the form of titles or contents of web pages that match the keywords that users enter when searching from selected websites. This content can be in the form of web pages, which can then be accessed directly within the application.","PeriodicalId":384219,"journal":{"name":"METHODIKA: Jurnal Teknik Informatika dan Sistem Informasi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129284911","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}

Currently, everyone needs information in a fast, short, and accurate time, therefore it takes media and tools that can support the work with various applications, media, and easy ways to access the information, one of them is an internet connection with hotspot service or wireless-based computer network (WiFi). SMA PGRI Aikmel is one of the private schools that have many enthusiasts because it has adequate facilities in conducting the teaching and learning process. Along with the increase of public trust in this educational institution, hence required a wireless-based computer network to support performance at academic part and to improve teaching and learning activity. By leveraging rapid technological advancements to enable equipment using cable technology to be replaced with wireless technology such as radiofrequency media. This research is qualitative research. Data were collected by observation, interview, documentation, and literature study. With the Network Development Live Cycle (NDLC) method, this study examines the development of wireless networks using Mikrotik devices and cisco packet tracer applications as simulation media from the development of network schemes.","PeriodicalId":384219,"journal":{"name":"METHODIKA: Jurnal Teknik Informatika dan Sistem Informasi","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132766412","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}

One way to secure shipping is to convert data into one that is not understood by encoding and insertion using cryptographic techniques. Cryptography is the study of system security, where the system needs to be secured from interference or threats from irresponsible parties. One of the cryptographic algorithms is the Blowfish Algorithm. The Blowfish algorithm is a modern cryptographic algorithm symmetrical key-shaped block cipher. The Blowfish algorithm is quite simple but strong enough because it has a long keyspace, making it difficult to attack. Encryption is done by using a certain key, so as to produce ciphertext (files that have been encrypted or encoded) that cannot be read or understood. The ciphertext can be restored as if it was decrypted using the same key when encrypting the file. The key length used can affect the security of the algorithm. The decryption flow is almost the same as the Blowfish Algorithm encryption, except in the P-array (P1, P2, ..., P18) done by invading. Information of a system is certainly stored in a database that is always possible to attack but using cryptography then the problem can be overcome. By using the Blowfish algorithm, information security in a MySQL database can be improved.","PeriodicalId":384219,"journal":{"name":"METHODIKA: Jurnal Teknik Informatika dan Sistem Informasi","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125526459","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}
