Abstract

PT XYZ company requires a Helpdesk Ticketing system that can enhance the efficiency of their IT support services. Hence, this study aims to design and implement a web-based Helpdesk Ticketing System using the Laravel framework. The system is designed to assist the IT department in efficiently responding to and addressing employee issues. The research methodology includes user requirement analysis, system design, and application development using the Laravel framework. During the requirement analysis phase, the author identifies user needs and determines the essential features that should be present in the system. Subsequently, the system is designed, considering efficient architecture and design principles. In the development stage, the author utilizes the Laravel framework to build the Helpdesk Ticketing System. The selection of this framework is based on its capability to expedite the development process and provide the required features for the system. Additionally, the author conducts testing using the Black Box Testing method to ensure the system's functionality. The outcome of this research is a web-based Helpdesk Ticketing System that efficiently assists the IT department in handling employee issues. The system allows employees to report problems through the website, and the IT team can easily respond to and manage incoming tickets. With the implementation of this system, it is expected that the efficiency of IT support services will increase at PT XYZ.

Abstract

Universitas Terbuka (UT) implements Distance Learning and since 2012 launched Ruang Baca Virtual (RBV) application to improve student learning services and provide alternative conveniences for students to utilize teaching materials online and help other universities wish to carry out online learning as an alternative solution to face-to-face replacement lecture services. Usability is one of the key factors for successful technology adoption. During the implementation of RBV, usability testing has never been carried out. The purpose of this study was to determine student perceptions of RBV usability. RBV usability testing was carried out using the questionnaire method using the system usability scale (SUS) instrument. The test results show that a SUS score of 72,66 placing RBV in the “acceptable” range, corresponds to a grade of C and the usability of RBV can be rated as “Good”.

Abstract

Social media has a vital role in general elections in Indonesia because social media is one of the platforms used by presidential candidates for campaigns to gain public support. General elections in Indonesia occur every five years. Many tweets talk about presidential candidates approaching the national election period. Not least, some buzzers deliberately use Twitter to carry out propaganda against a candidate or to bring down other presidential candidates with their opinions because information can spread widely and quickly on Twitter. Based on this, it is necessary to identify influential users in disseminating information related to the 2024 National Election, especially on Twitter. Various centrality methods were used in this study to identify influence users in sharing information about the 2024 National Election such us Degree Centrality, Closeness Centrality, Harmonic Centrality, Eigenvector Centrality, and Load Centrality. For the evaluation in this study, the results of each method were compared to one another to measure the similarity and correlation between the ranking lists of users who were influential in disseminating information about the 2024 National Election.

Abstract

Lombok Island is one of the islands that has many tourist areas. With so many tourist areas spread to various regions on the island of Lombok, an accurate and comprehensive tourist area mapping system is needed. The problem faced is that the existing mapping is still constrained regarding accuracy and data persistence. The solution offered in this research is the incorporation of geolocation data on the Mapbox platform to improve the accuracy and detail of data in mapping tourism areas on the island of Lombok. In this research, there are several stages carried out starting from data collection to testing. This research results in a tourist area mapping information system that applies geolocation data incorporation on Mapbox. The test results show an increase in accuracy of 8% from the previous mapping and a usability test score of 81 which means that the system developed is acceptable or feasible by users.

Abstract

This article compares the voltage drop on Lead-acid and Lithium-ion batteries used as an energy source for electric scooters. An experiment was conducted with five electric scooter users weighing 60.25 Kg, 70.60 Kg, 83.20 Kg, 95.40 Kg, and 103.75 kg to obtain data on voltage drop. Each user of this electric scooter carried out three experiments by circling about 1.07 Km at the Politeknik Negeri Bali area. This study proves that the voltage drop on the Lead-acid and Lithium-Ion batteries has a linear relationship to the weight of an electric scooter user with a 36V 400-watt BLDC motor load. The linear equation has an intercept value of -1.36766 and a slope value of 0.04791 for the Lead-acid battery. In contrast, the linear equation has an intercept value of -2.47064 and a slope value of 0.05417 for Lithium ion batteries. The average voltage drop across lead acid is 25% higher than that across Lithium-ion
