Fulfillment of academic information to support a decision in a college is very necessary, especially to support an academic planning and evaluation in higher education. Often management asks the student academic bureau to find out the number of students based on their class, period, number of graduates, class schedules to student grades. This encourages the student academic bureau to create a desktop-based application that can be used to find out more quickly the needs requested by management. By using the extreme programming (XP) model, it can accommodate the academic information needs of student affairs in universities in the form of a recap of academic data that can be presented in real time and quickly for the upper level management.

At present the technological developments that affect each system and in the aspects of online transportation and transportation are currently the most popular transportation because of the ease of using these transportation services in mobile phone applications. Some people express their opinions and opinions about users of public transport through social media sites and other websites. This opinion can be used as a material for sentiment analysis to find out whether public transport services are positive or negative. The purpose of this study was to find out the sentiments in the tweet opinion and to find out the results of the classification of the Naive Bayes method, C4.5 and the Random Forest algorithm that were used and compared. In this study, from the results of testing with performance measurements the three algorithms use Cross Validation, Confusion Matrix and ROC Curve.At present the technological developments that affect each system and in the aspects of online transportation and transportation are currently the most popular transportation because of the ease of using these transportation services in mobile phone applications.

As one of the educational institutions, Sekolah Dasar Islam Terpadu (SDIT) must be able to perform the data processing of students' grades well, because it will be used as one of the clear and valid benchmarks to determine student achievement level as learners. The conventional processing system of students' grades require a lot of time and effort for teachers and administrative staff to write down the marks in legs and report books, as well as to recapitulate student grades at the end of the semester. The manual processing of students' grades is also vulnerable to errors that come from inaccuracy in the process, thus affecting the accuracy of data and reduce the level of validity of information generated. The research discusses about the development of computerized academic information system in Sekolah Dasar Islam Terpadu (SDIT) with the aim to provide convenience in processing the data and accelerate the making of reports of achievement of learning. The scope of discussion is to focus on the management of student personal data, student's grades data, student mutation data, to the results of learning achievements through desktop applications using waterfall as the model of development system. With a reliable level of data accuracy, parents can obtain valid reports on student achievement, and SDIT stakeholders can receive strategic information for learning evaluation materials and determine future policy in school teaching and learning activities.

E-Inventory Information System at PT. Resik Nyaman Sejahtera. PT. Resik Nyaman Sejahtera is a company engaged in cleaning services that serve cleaning at apartments / hotels, restaurants, hospitals, universities, schools, supermarkets, villas, factories, offices, government offices or national private and other places. Constraints faced by PT. Resik Nyaman Sejahtera in carrying out existing projects is still using the manual process in inventorying / stocking of goods in and out of the warehouse so that it is difficult to find data and control the in and out of inventory / stock of goods in warehouses for ongoing projects or those that have been finished. Because of that the author proposes a intranet web-based e-inventory application that is made to overcome and minimize the problem. Broadly speaking, the application designed or developed consists of the process of recording data of goods, goods entering and leaving the warehouse, inventory of goods, and inventory reports. The results of this study produce an e-inventory application system that provides convenience for warehouse staff and administrators to manage and control inventory in the warehouse

This conventional election has several weaknesses, including difficulties in determining the validity of ballots, the process of counting ballots is slow. From the above problems, the authors propose to design and build a system to carry out elections using information technology called Electronic Voting. The method in this study uses the waterfall method which consists of the stages of needs Communication, Planning, Modeling, Construction, dan Deployment. The results of this study are to produce elections held with the District E-Voting.

Edu-tourism is the one of the most popular sub-type of tourism these days,where many countries in the world use Edu-tourism as one of the main sources of income. However, the lack of promotion with such a good planning and good infrastructure makes Edu-tourism on farms less attractive. In this research we try to build a plan to develop an information systems architecture in the Pondok Rangon ranch area to analyze operational activities on the ranch, designing information system development architecture using TOGAF ADM, and make a system information enterprise architecture design model that can be used as one of the facility to optimize the development of the promotion of the educational tourism industry on livestock especially the Pondok Rangon area. This research is only limited to the preliminary phase up to the technology phase so that the next research is expected to meet all the TOGAF ADM phases.

Prime numbers are unique numbers. Prime numbers are numbers that only have a dividing factor consisting of numbers 1 and the number itself. The prime numbers from 1 to n that are relatively small can be generated manually, but a prime number generator algorithm is needed to generate prime numbers on a large scale. This study compares three prime number generator algorithms, namely: The Sieve of Eratosthenes, The Sieve of Atkins, and The Sieve of Sundaram. These three sieve algorithms have their own differences in generating prime numbers. The Sieve of Eratosthenes uses a simpler method by crossing multiples of prime numbers and marking them as non-prime numbers. The Sieve of Atkins uses several requirements for quadratic equations and modulus in determining prime numbers. The Sieve of Sundaram has an algorithm similar to The Sieve of Atkins, but there are requirements for linear equations to determine prime numbers. This study aims to see a comparison of these three algorithms in terms of accuracy and speed in generating prime numbers on a large scale. The results of this study indicate The Sieve of Eratosthenes, Atkins and Sundaram algorithms can generate large numbers of prime numbers with good accuracy, this was tested by the Fermat Primality Test Algorithm. The conclusion that can be drawn from this study, The Sieve of Eratosthenes have a faster time to generate prime numbers on a large scale than the other two algorithms.

One of the food products that need to be reviewed for safety and is the most consumed is tomato sauce, although it contains a large amount of water in the sauce which has a long shelf life because it contains acid, sugar, salt, and is often given preservatives. The purpose of this study was to determine the tomato sauce using harmful preservatives such as the addition of borax. The dataset used in this study is the image of tomato sauce containing borax and not with the number of samples 400 images of tomato sauce with different comparison percentages starting from the image of tomato sauce with 70% borax content, image of tomato sauce with 50% borax content, image tomatoes with 30% borax content and image of tomato sauce that does not contain borax. A sampling of images using a camera phone brand xiaomi note 5 by mixing borax in the original sauce before the sample is used for the training and testing process. The classification results show the gray level co-occurrence matrix (GLCM) method is quite optimal in classifying tomato sauce data containing borax and not with an average percentage of the introduction of 88%.
