Music is something that everyone is interested in, but not everyone can play a musical instrument, especially a guitar. Many people who love this instrument but many also have not understood about guitar tuning in case of fals there is a guitar string. How to tuning the guitar will be difficult for a beginner who has not understood about guitar tuning poses. The easiest solution is to use an electronic guitar tuner, but the tool is quite expensive and less flexible to carry anywhere. In this thesis, the author designed an android-based guitar tuner application to solve the problem. Guitar tuner application that will be made using Fast Fourier Transform algorithm that serves to calculate Fourier Discrit's transformation quickly and efficiently, and using Harmonic Product Spectrum algorithm to perform frequency harmonization process to know the basic tone frequency of guitar strings and process the frequency so as to produce output in the form of needle indicator parameters in the form of interface. From the results of this study obtained results in the form of guitar tuner application that is able to function well to help the process of guitar tuning.Keyword : Aplikasi, Android, Tuner Gitar, FFT(Fast Fourier Transform), HPS(Harmonic Product Spectrum), Frekuensi

Sundanese has unique names in its daily scope, such as naming animals. Learning the names of animal child using Sundanese is one of the activities in preserving Sundanese culture. However, especially elementary school students have lacked interest in learning Sundanese, one of them concerning the names of animal child in Sundanese, this is because the learning medias are less attractive, there are no developments in the packaging of Sundanese materials, especially the introduction to names of animal child and the absence of a dictionary regarding to the names of children in the school. Therefore, an interesting application is needed to help learning Sundanese so that students have an interest in learning the names of animal child in Sundanese. The result of this study is a game application, in which there are material about the names of animal child in Indonesian and Sundanese and there are questions that must be answered in a certain time limit to practice Sundanese language skills and to know the extent to which students understand Sundanese. By using the Linear Congruent Method (LCM) algorithm to scramble the questions that appear in the game and Knuth Morris Pratt (KMP) for matching strings in the game. The application is built using the C# programming language and the development tools used are Unity. And the system development method in this application uses the Rational Unified Process (RUP) method, while the method for designing the system uses the Unified Modeling Language (UML).

The conventional learning process carried out face-to-face, is less effective as a source of learning, because the focus of students' interest has now shifted to their device so that students have difficulty repeating learning material. This study aims to produce learning media based on mobile learning on the android platform which is used as a source of learning fiqh applications for students. This mobile learning application is built by applying the Fisher Yates Shuffling algorithm or commonly known as the Fisher Yates algorithm which is now widely used in the process of developing randomization applications. This randomization method is the optimal randomization method in application development, being able to randomize the amount of material about the science of jurisprudence and prevent cheating users who only memorize answers without understanding the material when the questions are fixed or not random. Applications are built using MySQL as a database designed to manage and manipulate data quickly and easily. PHP and Perl are used as scripting programming languages for the internet and collaborate on the Android platform. The system development method used is RUP (Rational Unified Process) by collecting various best practices found in the software development industry.System testing is done using a white box and black box testing shows that the Fisher Yates algorithm can be applied in the mobile learning quiz application as a randomizer about questions. User Acceptance Model (UAT) test results show that this mobile learning application can help the process of learning the science of jurisprudence as well as being a reference in seeing the ability of students to learn the science of jurisprudence.

Classification of data with unbalanced classes is a major problem in the field of machine learning and data mining. If working on unbalanced data, almost all classification algorithms will produce much higher accuracy for majority classes than minority classes. This research will implement the Synthetic Minority Over-sampling Technique (SMOTE) method to overcome unbalanced data on credit customer data in Rawamerta teacher cooperatives. The research methodology uses SEMMA with the stages of research Sample, Explore, Modify, Model, and Asses. The Sample Phase was conducted to choose the data of the Rawamerta Teachers Cooperative credit customers for 2015-2017 with a total of 878 data with the attributes used namely income, total deposits, loan amount, duration of installments, services, installments, and credit status. The Explore phase analyzes current classes which are categorized as majority classes because there are 813 data, while traffic classes can be categorized as minority classes because there are 65 data. The data shows an imbalance of data between the two classes. The Modify stages perform the 500% SMOTE process. The Model Stage classifies using Naïve Bayes. Naïve Bayes modeling with SMOTE produced 1131 successfully classified data correctly and 72 data were not classified correctly while without SMOTE resulted in 818 data was classified correctly and 60 data were not classified correctly.Keywords: Naïve Bayes, SMOTE, unbalanced data

Koperasi Kemuning Persada (KKP) is one of the companies engaged in lending services, where the main task of the KKP must consider the size of the loan to be given to prospective customers. There is often an error in granting loans to prospective customers because the valuation used is not an objective parameter, especially in terms of determining the size of the proposed loan size, it causes several problems in terms of decisions that must be taken by the relevant branch head. Therefore it is necessary to have a tool or system that can help in terms of decision making of the branch head, related to large / small loans granted. The method used by researchers in designing this Decision Support System is the Fuzzy Tsukamoto method, where the parameters used as criteria in granting credit into 3 (three) things, namely income, collateral and length of business. While the research approach in designing this system uses Object Oriented methodology, assisted with data collection using interview and observation methods. Some tools used to analyze business processes and functional requirements use tools from the Unified Modeling Language (UML), including Usecase diagrams, Sequence Diagrams, Class Diagrams, Activity Diagrams. Applications that researchers design are web-based using the CodeIgniter Framework, programming language uses PHP and HTML while database design uses MySQL.Keywords: SPK, Credit, Fuzzy Tsukamoto
