Abstract

In determining the scholarship recipients at the Sekolah Tinggi Teknik Musi there areseveral criteria used to conduct the assessment. Criteria - such criteria as grade pointaverage (GPA), parental income, elderly dependents, semester, TOEFL, and religion.For efficiency and effectiveness of work then the right decision making is needed.Thisfinal report aims to create a decision support system using the method of AnalyticHierarchy Process to assist decision makers in determining who will receivescholarships based on established criteria. Decision support system scholarshiprecipient has the ability to analyze the scholarship recipients by using AHP method,which will be comparisons between the criteria with other criteria and alternatives inthis case the student compared to each other to obtain comparison graphs.The methodused in the writing of this report is a waterfall method by conducting interviews andreferences to obtain data. Making this system starts from the analysis of systems usingmodeling in the form, Context Diagram, DFD, process specifications, data dictionaryand ERD, design, implementation, and testing the system. All the stages passedthrough, except for installation and maintenance phases. The implementation usingprogramming language Visual Basic 6.0 and SQL Server 2000 database. Testsconducted only limited to the functional system of just using black-box testing. It isexpected that awardees decision support system can be implemented at Sekolah TinggiTeknik Musi.

Abstract

information. By using various techniques, many people are trying to accessinformation that they are should not have access to. With the development ofscience, the application of information security techniques and data that have beenused in ancient times can be an alternative in securing datacommunications. Cryptography is a science and art to maintain the security ofmessages sent from one place to another. RC4, one cryptographic algorithm, is widelyapplied to encrypt information. Cryptography can still be broken even if the processtakes time, cost and effort. Other data security techniques are also quite popular issteganography. In contrast to cryptographic techniques, steganography can reducesuspicion because the message is disguised is hidden in another file. LSB is one ofsteganographic methods. LSB widely applied to insert a secret message into a digitalimage.This software is made in order to secure the secret message into a digital imageusing the RC4 algorithm and the method of LSB. The software is built using thewaterfall model of software development.The results of the development of this softwarehas been able to secure the secret message in the form of text into a digital image witha BMP format using RC4 algorithm and the method of LSB.

Abstract

Instant messaging (IM) a service that is used as a communication medium has severaladvantages since we can communicate in real-time, fast, and with very low cost. Theseadvantages led to the growing number of IM users of the service both from business,military, and government. However, since security aspects were not a design prioritythe emergence of threats such as eavesdropping and replay attacks also increased inrecent years. Therefore,additional security measures are required to prevent the threat.Secure Instant Messaging (SIM) is a software that implements the technique IMencryption, key agreement and authentication with the aim of preventing eavesdroppingand replay attacks. SIM the encryption of the message before it is transmitted overcommunication channels. Based on the results of testing, the process of authentication,encryption and decryption do not degrade performance significantly based on time andmemory used. Key agreement requires an average time of 25-32 seconds. This causesconsiderable delay occurred in the SIM application. On memory testing, key agreementrequires a 56% memory.

Abstract

Fact finding is a difficult task and need a long time. This process can be disrupted alsoby personal perception researchers. For information systems workers, fact-finding isone of the main tasks in performing the steps of analysis and design of informationsystems. Therefore, the discovery of the facts is a competence that need to be owned bya student who will be working at information systems environment. The learningmethod uses Problem Based Learning (PBL) is a learning method for understandingthe concept of Fact Finding uses Ishikawa diagrams and Pareto analysis. Studentstargeted has ability to level the synthesis of Fact Finding, which is able to apply indifferent cases, especially in information systems projects.

Abstract

Penggunaan Teknologi Informasi di Perpustakaan FMIPA Universitas Pakuan menjadisuatu keharusan dalam meningkatkan kinerja dan produktifitas.Informasi yang diolahharus bersifat efektif, efisien, rahasia, terintegrasi, tersedia, sesuai, dan dapatdiandalkan.Untuk menilai sejauh mana pengelolaan TI telah dilaksanakan dengannbaik, perlu dilakukan penyesuaian standar manajemen teknologi.Metode COBITadalah salah satu standar manajemen teknologi.Tahapan Metode COBIT yangdilakukan adalah tahap informasi, tahap perencanaan dan organisasi, tahap akuisisidan implementasi, tahap pengiriman dan dukungan, serta tahap pemantauan. Setelahitu, dengan menggunakan Metode COBIT ini akan diberikan penilaian melaluiwawancara dan kuesioner, sehingga dapat diketahui tingkat kematangannya (MaturityModel). Dengan demikian diketahui temuan-temuan, baik yang sudah baik, buruk,maupun yang masih perlu dikembangkan. Akhirnya diberikan rekomendasi untukmeningkatkan mutu perpustakaan FMIPA UNPAK.

Abstract

lokasi pameran menjadi salah satu titik keputusan terpenting. Dengan memiliki lokasipameran yang strategis, tujuan pelaksanaan pameran produk dapat tercapai.Penelitian ini dimaksudkan untuk menentukan lokasi pelaksanaan pameranmenggunakan Simple Additive Weighting (SAW) Method, metode ini didasarkan padakriteria-kriteria tertentu, kriteria yang akan digunakan sebanyak enam kriteria danempat alternatif lokasi pameran. Berdasarkan perhitungan yang dilakukan secaramanual maupun dibuktikan dengan sistem yang dibangun dengan Borland Delphimendapatkan hasil yang sama. Namun, keputusan akhir tetaplah berada di tanganpengambil keputusan. Apakah mengikuti rekomendasi dari sistem ataukah memutuskanuntuk memilih alternatif lain.

Abstract

Climate is average condition for certain time period. The one of few factors influencethe climate is rainfall. This research develops a system which can predict and giveinformation of monthly rainfall prediction and also for the next few months.Climatology data from BMKG from 2000 to 2009 is need in this research. The dataconsist of seven variable which are temperature, sunlight condition, air pressure,humidity, wind speed, wind direction and evaporate. This research uses ExponentialSmoothing for rainfall prediction and K-Nearest Neighbor that need for rainfallprediction classified. The result shows that the prediction accuracy is 58, 33%.
