Abstract

The success of a digital product, relies heavily on the inseparable relationship between User Interface (UI) and User Experience (UX). Although UI is a fundamental aspect of UX, it's imperative to acknowledge that the UI's design, functionality, and ease of use are pivotal factors that can make or break a digital product's success. A top-notch UI design can significantly enhance the UX, while a deficient and convoluted UI can lead to a less-than-stellar user experience. In this study, we undertake the task of evaluating the UI quality of "Endorsfy" – an Influencer Marketing Mobile Application. We employ the Single Ease Question (SEQ) method and the Maze tool to assess the UI quality and determine if it meets the standards for optimal usability. Additionally, this evaluation will consider the usability aspect of the application to ensure that it delivers a seamless user experience. Our ultimate objective is to guarantee that "Endorsfy" achieves the highest standards for UI quality and usability, providing users with an unparalleled experience when using the application.Keywords: User Interface, Single Ease Question, Influencer Marketing, Mobile, Usability

Abstract

Accidents in Indonesia are increasing every day. Based on data from the Central Statistics Agency, the range from 2019 to 2021 shows that there were 320,084 accidents in which 74,466 people died, 33,779 people suffered serious injuries, 368,773 people suffered minor injuries, and resulted in material losses of Rp. 699,888,000,000.00 due to traffic accidents on the highway. This study aims to help reduce the death toll and also traffic accident reporting by utilizing the daily use of cellphones and smart gadgets. To overcome this problem, the authors created a design solution using the prototyping method which was implemented in a mobile application. In the prototype, the user can make an emergency call to call an ambulance so that the victim can quickly get help, and also the user can easily report a traffic accident. Hopefully the design of this application can reduce victims due to traffic accident incidents. Keywords: Reporting, accidents, Traffic, Mobile, Application

Abstract

Optimization algorithms are algorithms that are needed to properly train Neural Networks. Optimization algorithms help improve model performance by modifying the attributes of the neural network, such as weights and learning rate to further enchant the model. Gradient Centralization is a new optimization algorithm that optimizes by centralizing gradient vectors to have zero mean. This paper focuses on finding the optimal learning rate for Gradient Centralization and uses that learning rate to create a classification model to classify natural scene images. The optimal learning rate obtained by this research is 2e-5 and the model obtained 84,17% mean recall, 84,39% mean precision, and overall 83,60% accuracy.

Abstract

In order to preserve Indonesian culture and raise reading interest, website named Kisahnesia was created. This study focuses on analyzing the User Interface (UI) of the Kisahnesia application using the System Usability Scale (SUS) methodology. The objective of the study is to assess the usability of the application and determine the level of user satisfaction. The SUS questionnaire was administered to a sample of users, and based on the analysis of the collected data, the application obtained a score of 78.375. This score indicates that the Kisahnesia application has passed the usability test, demonstrating a high level of usability and user satisfaction. The findings suggest that the UI design of Kisahnesia is effective in providing a user-friendly and intuitive experience, contributing to the overall positive user perception of the application's usability.

Abstract

Beef is one of the best foods to eat. However, to identify beef manually has a weakness, namely the limitations of human visual abilities. Therefore it is necessary to have an indicator of the level of freshness of the meat. This study uses image augmentation to change or modify images and use Convolutional Neural Network (CNN) with VGG16 architecture to perform image classification. The accuracy obtained with epoch 15 and the distribution of data by 80% of training data and 20% of validation data is the highest accuracy obtained, which is 97.14% and when tested with validation data it gets an accuracy of 98.68%. Overall, the model that has been used can classify the freshness of beef well.

Abstract

This research aims to develop an ontology related to the domain of Balinese folklore. Balinese folklore is an important part of Bali's cultural heritage and has moral values, as well as being an inspiration in art and performance. Ontology is a method to organize and categorize information in a structured way, and has been widely applied in various fields. However, research on the ontology of Balinese folklore is still limited. This research will propose and develop a comprehensive and structured ontology model for Balinese folklore. The steps to be taken include analysis of relevant ontologies, development of an ontology schema, organization and classification of information, and testing and validation of the ontology model built. The method used in this research is methodology, which includes the stages of specification, knowledge acquisition, conceptualization, integration, evaluation, and documentation. The result of this research is a structured Balinese folklore ontology that has been evaluated using SPARQL queries. This ontology can be used as a source of information and reference in learning and utilizing Balinese folklore. Keywords: Ontology, Balinese folklore, Methontology, SPARQL Query

Abstract

Guitar tuning is a crucial step in preparing for playing, ensuring accurate sound production. In response to this need, our research led to the development of a web-based application dedicated to facilitating precise and straightforward guitar tuning. Leveraging web technology, this application offers users practical tuning experience without the need for additional software installation. By implementing comprehensive tuning features and employing the Fast Fourier Transform (FFT) method, our application guarantees accuracy in detecting and analyzing the spectrum of incoming sound vibrations. This technological approach ensures that users can confidently tune their guitars, avoiding mistuned strings. The decision to create a web-based app aims to optimize device space utilization, as it only requires a standard browser, readily available on all operating systems. In addition to tuning functionality, the application enriches the user experience by providing a collection of guitar chords for each note. This feature enables users to practice and play songs with adjustable transposition and speed. To assess the application's functionality and reliability, we conducted 100 trials using the BlackBox method, focusing on tuning the six guitar strings (e-b-g-d-a-e). The results demonstrated a remarkable 99% accuracy, affirming the system's effectiveness in facilitating precise guitar tuning. In conclusion, our research yields a practical, intuitive, and highly effective web application for users to tune their guitars with confidence and ease. Keywords: Web, Guitar, Fourier Transform, FFT

Abstract

Delivery service is a promised business so many new companies are opening this business. However, it is not uncommon for parcel delivery to be delayed. From the field of Informatics, determining the courier route is included in the Traveling Salesman Problem. The TSP problem can be solved using several algorithms, one of which is the Artificial Bee Colony or ABC algorithm. Artificial Bee Colony algorithm adapted from the behavior of bee colonies in search of food. In this study, primary data is used in the form of destination points in the Bangli sub-district area of ??PT Global Jet Express Bangli delivery of packages using 20 destination points. The results of this system showed that the three parameters tested, namely the number of bees, the maximum limit and the maximum iteration did not show significant changes for the best distance. In this study, the shortest distance obtained using the Artificial Bee Colony algorithm is the number of bees is 10, the limit is 20 and the maximum iteration is 40 with a value of 38,42 km.
