Abstract

PT. Nippon Indosari Corpindo,Tbk. is one of the companies engaged in the food industry with its flagship product, namely bread with the brand "SARI ROTI". PT Nippon Indosari Corpindo,Tbk has been established since 1995. At PT Nippon Indosari Corpindo,Tbk, according to the author, the online buying and selling system used is not yet effective and efficient, because customers have to click the link to whatsapp to order, if the order has been entered then from the agent The center provides information to the nearest agent according to the location of the order ordered by the customer, and afterthat the nearest agent canonly send the order. Therefore, there is a lack of efficiency in the purchasing system. The problem isthat it does not yet have a prototype user interface for the Sari Roti mobile application. Based on these problems, user interface design was carried out and produced a prototype of the Sari Roti mobile application using a user centered design (UCD) model and for evaluation of the initial design using a usability scale (SUS) system to 11 respondents. This research is successful in designing a user interface that can view product lists, product details, make transactions, and order status. The initial design evaluation uses a usability scale system with initial calculations showing an average valueof 82,withGrade B

Abstract

PT XYZ Tbk is the largest transportation rental service company in Indonesia. However, the process of submitting a lease from a customer still takes a long time and a lot of resources because it is done manually. It's very important for an organization to facilitate the business process with digitalization and to change physical files and documents to digital files (paperless) in the form of e-documents accompanied by e-digital signatures so that the process becomes faster, more effective and efficient. Therefore, this research purpose is to propose an E-Rent vehicle rental system to digitalize the current business processes. To determine the proposed design, research was conducted by analyzing user requirements, system requirements and conducting design modeling using the Object Oriented Analysis and Design method. Based on the result of the research conducted, it is expected the proposed system can meet the needs of the users in the vehicle rental process., both the users in the company and the customers.

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

Puwrakarta City is one the regencies in West Java that is currently developing. Purwakarta city is located in a geographical area thatis rich in natural attraction, culinary tourism, and cultural tourism so that the city of Purwakarta become a tourist attractio, but not all tourist attractions in the city of purwakarta are know by local tourists and tourists outside the srea who want to visit and the lack of information anda there are many remote areas which are very unfortunate to miss its tourist attraction. Therefore, a mobile-based tourism application was made to make it easier for tourists to find tours. This software development uses the waterfall method to the dev stage, software modeling uses the Unified modeling Language (UML) modeling which consists of 4 stage, namely use case diagrams, activity diagrams, sequence diagrams, and class diagrams, with programming language using Dart, Firebase database, and using Flutter. This research produces a mobile-based application that has information about natural tourism, culinary tourism, and cultural tourism to that it can be used to disseminate between locak tourists and tourists outside the area in Purwakarta City.
