Abstract

With the existence of computers and applications, it is hoped that it can help humans or users in processing and presenting accurate and fast information so as to obtain effectiveness and efficiency, both in terms of time and cost. However, this still really requires a security system in the delivery of a document or information so that it cannot be used by other unauthorized parties who can harm the owner of the document or information both materially and immaterially. Digital signature is an electronic signature that can be used to prove the authenticity of the identity of the sender of a message or the signer of a document, and to ensure that the contents of the message or document are sent without changes.(Junadhi, 2019).The application development model used is the Extreme Programming model with the stages of planning, design, coding, and testing, using the Unified Modeling Language (UML) design, namely Usecase Diagrams, Activity Diagrams, Sequence Diagrams, and Class Diagrams. The builder software used is XAMPP and uses the Codeigniter framework and the PHP programming language with a MySQL database, and uses Black Box Testing as its testing. The conclusion that can be drawn from the results of making application for student activity proposals using web-based digital signatures with this extreme programming method is that the proposal tracking feature can make it easier for the Student Association to see if the proposals have been submitted and digital signatures using qr-code can make it easier student associations to directly print signature documents without coming directly to several parties, can make it easier for the Head of Study Programs, Student Executive Board, Head of Student Affairs and Head of STT to approve or approve proposal documents through applications at any time, and make it easier for the Head of Field Staff Students to monitor the delivery of proposal documents from the Student Association. So this application is still in the tri dharma of college.

Abstract

After the case of alleged child rape in East Luwu which was stopped went viral in the aftermath of many other cases of sexual violence that were considered by the police to be inconsistent with procedures. After the hashtag #PercumaLaorPolisi appeared #PolriSesuaiProsedur hashtag became a trending topic on Twitter. This study discusses the sentiment of police performance on twitter users, aiming to measure how much sentiment the performance of the police according to twitter citizens who earned. The topic of this study is a mining text that uses the naïve bayes method. Text mining is a computer-based algorithmic technique/approach to gaining new knowledge hidden from a set of texts. The data from crwalling on twitter were analyzed using naive bayes which is a method for analyzing. Naive Bayes' algorithm is very effective in classification or classification problems. This algorithm works based on existing probabilities to determine the probability of the future. The steps in the Naïve Bayes method are preprocessing which includes transformation, tokenization and filtering processes. It is followed by the weighting of words such as TF-IDF and ends with classification and evaluation. As a result of this study, according to tweet data processed using the orange application and confusion matrix calculations, the police performance sentiment entered the neutral classification of 75.8%, negative 58.1% and positive 39.5% in the last order, as well as the resulting model at an accuracy value of 0.929, precision 0.933, recall 0.923, and f-measure 0.954

Abstract

The use of information systems in an organization has many advantages, just like the use of a website for institutions or companies is very helpful in conveying information, one of which is in administrative matters that can be applied using information system technology, namely for scholarship management. Scholarships can be interpreted as providing financial assistance to individuals, with the aim of being used for the continuity of the education taken. In the process of submission and approval in the selection of scholarship admissions that run in the field of student affairs at this time, it is still carried out manually both from the process of collecting files, selection to determining scholarship recipients is carried out manually by the head of the study program. Therefore, the field of Student Affairs at STT Wastukancana Purwakarta, requires an information system that can help the process of applying for and approving scholarships digitally carried out by students of each study program coordinated by the student affairs field. The system development method used is the Rapid Application Development (RAD) model consisting of the Requirements Planning, RAD Workshop Design, and Implementation stages. The results of this study produce a scholarship management information system that can solve problems in the scholarship admission selection process by being able to do it digitally from the process of informing the existence of scholarship opportunities, submission, selection to determining scholarship recipients.

Abstract

Vehicle care is one of the businesses that is quite profitable with quite large capital. However, with this capital it becomes a fairly large and long-term income, and from this capital every year the price of this capital will definitely increase because of the area of the land. However, in business, there is a problem that often occurs in each of these safekeeping, namely realtime accounting and data in photos and numbers. Then this research aims to make it civil in managing the daycare. The model and method used uses Extreme Programming (XP) development and, why did I take mobile programming because in this case study it is better for device users who are indeed flexible.The feasibility of this system is seen from the point of view of its functionality and according to the user from what is needed according to the case study. The programming language used is Java, and testing is to display the success of system functionality using a black box, then for modeling using the unified model language (UML) for flow using this system, the database used is firebase.The purpose of this research is to get a solution to the problems that exist in the place, namely in data collection and reporting to the owner by providing input within certain hours and then conveying it to the owner, with this application providing solutions to problems that occur at this research location.

Abstract: As many smartphone users with the Android operating system in this digital era applications become one of the tools that can help users in various ways, one of which is to buy necessities, this can be used in companies that usually sell their products in stores that often need effort for consumers to get products. CV. Cipta Rahayu is a company engaged in the sale of agricultural materials, the manual sales process often causes problems such as in processing transaction data, and it takes a long time to make reports, and at least customers because customers have to come directly to the location to order goods, after that it is processed and delivered to the customer's location, this will be difficult for customers whose position is far from the CV location, Often customers also choose to buy goods in the nearest place at a much more expensive price. Therefore, the company needs a mobile application sales system with the name Tani Rahayu application that can facilitate the sales process. The purpose of this research is to design and build an Android-Based Rahayu Farmer Application Using the Extreme Programming (XP) Method. The result of this study is the creation of the Android-based Tani Rahayu application, which will make it easier for customers to order goods without having to go to stores that take distance and time, then solve problems with shop owners or CVs in the process of customer orders and bookkeeping, then overcome customers switching to purchasing agricultural materials at other stores due to the remote location of the store, and attract many more other customers.
