Abstract

SMS (Short Message Service) is a service to send a sort message that many used in telephone, but in service of a SMS provider have infrequent method to make data of it be more secure, this making service of SMS have so many security gap that making data possibly lost or will be a third person who can access data of SMS. Android is a lateset mobile operating system from Google, android make programmer possibly develop the application easly to use in smartphone and tablet. Cybercryp SMS is an application that designed for android system that will use to secure data that use service of SMS. RC6 algorithm for encryption and decryption will be use in service of sender and receiver message from Short Message Service, that will use a private key and symmetric password for make data will be more secure and security gab can be resolved.

Abstract

Computer network is a technology that is widely used by companies that functions to connect one location to another. The use of the internet as a communication medium is not only very beneficial for the company, but still has weaknesses in terms of security. The obstacles faced are how to access data in the office and turn employee devices into a network required for API testing without having to come directly to the office, of course with a very adequate level of security. The solution that can be used for this problem is to build an OpenVPN server as a tunnel to be applied to help employees access the office network or other employees. By implementing the system, testing the API on mobile applications, which runs on the local office computer or runs on client computers or other employees

Abstract

Water is a basic human need that plays the most important role in human life in order to sustain human life. As time goes by, the need for clean water is very much needed by the community. The high need for water is the driving force for practical drinking water. In this final project, the application is made using Android Studio as a text editor, Sublime as a text editor to create an API, and MySQL which is useful as a system manager on the database on the server. In the application there is access as a customer, depot owner and as an introduction to gallons. The customer will then process the gallon water order and the depot owner will process the order that has been placed by the customer and send the order data to the gallon controller. When the gallon delivery person delivers the order, the customer can access the gallon delivery tracking process. Keywords: Android java, API, Tracking

Abstract

Intisari - Pada Akademi Komunitas Negeri Pelalawan (AKNP) diperlukan sebuah sistem informasi yang nantinya akan memudahkan pengelola dalam mengolah data-data yang berhubungan dengan kepegawaian sehingga data tersebut tersimpan dan terkelola dengan baik menggunakan sebuah basis data. Sistem informasi kepegawaian ini memiliki 36 buah fungsionalitas/fitur. Kepuasan pengguna terhadap fungsionalitas sistem ini akan dianalisis menggunakan metode Kano. Kusioner Kano yang dibuat  berdasarkan  fungsionalitas  sistem  disebar  kepada  24  orang  responden  yang  merupakan pengguna  sistem ini.  Dari pengolahan  kuisioner,  didapatkan  bahwa  seluruh  fungsionalitas sistem berada pada kategori one-dimensional dimana seluruh fitur telah memenuhi kebutuhan kinerja sistem. Oleh karena itu pengembangan/perbaikan sistem informasi akan difokuskan pada penambahan fitur yang menambah daya tarik sistem informasi. Kata Kunci - sistem informasi kepegawaian, kepuasan pengguna, metode Kano

Abstract

This research focuses on improving the accuracy  of email and twitter classification. Spelling mistakes and lack of matches with bag of word causes the low accuracy in classifying. This research used naïve Bayes as a text classification algorithms. Text is divided into three categories: personal, work and family. To achieve maximum likelikehood value for  the category, a better preprocessing techniques is needed. It is necessary for the process to normalize the preprocessing and search for words that correspond to classes in the bag of word. So that the text can be classified by category or has a higher precision accuracy.

Abstract

Cooperatives are one of the business units which purpose is to help the economy of small and medium-sized communities. One of the cooperatives in the city of Padang, West Sumatra, Indonesia is KPN Kapur Warna. The routine business unit managed by KPN Kapur Warna is for savings and loans. So far, the savings and loan process is still done manually, including determining the eligibility of members to receive loans. Determination of the eligibility of members is carried out less objectively, by only looking at the profile of participants in general and the decision-making process is only carried out by one person, namely the chairman of the cooperative. The process that has been carried out so far has often resulted in wrong targets, namely providing loans to members who are not appropriate, resulting in bad credit or delays in paying monthly installments of participants. Therefore, we need a group decision support system that can help solve the above problems. In this study, a group decision support system was made using the AHP, TOPSIS and BORDA methods using five main criteria. The AHP method is used to determine the priority value for each criterion and the TOPSIS method is used to rank each alternative. Each decision maker performs the same process with the two methods, and then voting is carried out using the BORDA method of combining assessments for different decision makers. This study succeeded in providing a reference in determining the eligibility of which members are entitled to receive loans from cooperatives, with results that are more subjective and can help cooperatives in their work efficiently.

Abstract

Fuzzy Mamdani has been mostly used in various disciplines of science. Its ability to map the input-output in the form of a surface becomes an interesting thing. This research took DSS case of a scholarship grantee. Many criteria in taking a decision need to be simplified so that the result obtained remains intuitive. The model completion by conducting two stages consisted of two phases. The first phase consists of four FIS blocks. The second phase consists of one FIS block. The FIS design in the first phase was designed in such a way so that the output obtained has a big score interval. FIS output at the first phase will become FIS input at the second phase. This big value range becomes good input at FIS in the second phase. Each FIS block has different total input. Until the surface formed must be seen from various dimensions to assure trend surface increasing or decreasing softly. This kind of thing is conducted by observing the movement of output dots kept for its soft surface form. The output dots change influenced by the membership function, the regulations used, total fuzzy set, and parameter value of membership function. This research used the Gaussian membership function. The Gaussian membership function is highly suitable for this DSS case. This article also explains the usage of a fuzzy set in each input, the parameter from the membership function, and the input value range. After observing the surface form with an intuitive approach, then this model needs to be evaluated. The evaluation was done to measure the model performance using Confusion Matrix. The result of model performance obtained accuracy in the amount of 85%.
