Abstract

PT XYZ provides a digital platform for the national logistics ecosystem and is connected to a global network. PT XYZ applies Agile as a project management methodology so that each team member can focus on continuous improvement and delivering value to customers. The framework used is Scrum during software development to complete work in Agile. However, there are problems during software development, such as failing to meet the targeted deliverables. This research evaluates the implementation of Scrum in PT XYZ and provides recommendations for improving the software development process using Scrum Evaluation Metrics based on Scrum Guide 2020 and Essentials Scrum. The research utilized mixed methods, combining quantitative data collection through questionnaires with qualitative methods involving interviews with Scrum Master and stakeholders, followed by a review of company documents. The result was processed using the Agile Maturity Model's Key Process Area (KPA) rating. The research shows that overall, the KPA rating value of 87.39% is interpreted as Fully Achieved. Recommendations for improvement focused on 27 recommendations for 61 practices that were not Fully Achieved, with high priority given to 15 recommendations. This evaluation and recommendation aim to improve the implementation of Scrum in PT XYZ and overcome the problem of backlog targets not being achieved in the Fulfillment squad.

Abstract

Software development in the era of global competition requires strategic technology management to enhance a company's competitiveness and economic performance. The main challenges in this process include project complexity, changing requirements, and time constraints, which often lead to project failures globally. In Indonesia, only 27% of information system projects are completed on budget and on time, highlighting significant issues in software development. AI assistants have emerged as an innovation with great potential to address these problems. With features such as code completion, code interpretation, and bug detection, this solution has the potential to increase software developers' productivity in the future. Given this context, this research aims to identify the factors influencing the intention to adopt AI assistants, particularly among software developers. The study was conducted using PLS-SEM and applied factors from common technology acceptance theories such as TAM and UTAUT. Data collection instruments were distributed using self-selection sampling and snowball sampling (N=165). Major factors in UTAUT such as effort expectancy, performance expectancy, facilitating conditions, and social influence were found to be significant in influencing attitudes or adoption intentions. Additionally, AI-specific factors in the context of UTAUT extension, such as AI literacy, were found to have an indirect effect on attitudes and behavioral intentions, moderated by other factors. It is hoped that the findings of this research can help stakeholders evaluate their strategies if they wish to adopt AI assistants and provide academic impact through scientific publications that can complement existing literature, expanding the understanding of AI integration in the professional IT realm.

Abstract

Self-service has been widely adopted by various companies worldwide for different purposes; for example, in customer service settings, it automates repetitive and simpler tasks handled by agents. However, self-service systems for resolving customer issues have limitations. This study thus aims to evaluate the usability of the self-service system on the help center of an e-commerce app. Usability evaluation was conducted using both qualitative and quantitative methods. Quantitative data were collected through a survey with demographic and introductory questions, the System Usability Scale (SUS) questionnaire, and follow-up questions. In total, 200 responses were collected (195 of which were valid). Since the average SUS score was 67.35, the data analysis revealed that the self-service system has usability issues, particularly in learnability and efficiency. Additionally, usability testing and in-depth interviews were conducted with 12 participants to collect qualitative data to be analyzed using thematic analysis. Based on these findings, the study concludes that the development team can prepare a plan to enhance the user interface of the self-service system on E-Commerce XYZ’s help center to enhance usability.

Abstract

Halal Network International (HNI) is considered as one of the sharia MLM-based companies in Indonesia. In order to fulfill the sales management needs, HNI developed HSIS application. The aims of this study are to conduct usability testing and to design alternative interface design recommendations for the HSIS Mobile application by using the User-centered Design (UCD) process. This study applied the System Usability Scale (SUS) Questionnaire, Open-ended Question (OEQ), and Task Scenario within Usability Testing (UT) as research instruments. There were 81 respondents involved in filling out the questionnaires. Furthermore, UT Phase 1 was conducted by involving 14 respondents. The results of these processes were categorized, and the design solutions were mapped based on Nielsen's Ten Usability Heuristic of Interface Design and Shneiderman's Eight Golden Rules of Interface Design. The alternative design solutions were tested again in UT Phase 2 and they showed a significant decrease in the number of usability issues. Thus, it proves that the alternatives design can provide positive improvement in the usability and user experience of the HSIS Mobile application.

Abstract

Manual warehouse systems in Indonesia cause tracking and storage issues, increasing the risk of damage. Implementing Particle Swarm Optimization (PSO) in Automated Storage and Retrieval Systems (AS/RS) can optimize travel paths, reduce errors, and enhance storage efficiency. Parameters such as particles, iterations, and inertia are applied in this system. This study integrates PSO with Arduino-based AS/RS using the VDI 2206 method, with AS/RS racks designed in a 4x4 matrix. In various case studies, PSO successfully reduced travel distances by 1% to 32% and operational time by 5% to 21%. PSO effectively enhances the operational efficiency of AS/RS by optimizing travel routes, thereby reducing the time needed for storage and retrieval operations. Additionally, it is important to note that the reduction in travel distance is influenced by the initial input addresses without PSO, which might already be near optimal. Thus, while PSO significantly improves efficiency, the extent of reduction can vary based on how close the initial input addresses without PSO are to the optimal route.

Abstract

The skin is an important organ that protects the human body, so early treatment is essential to prevent diseases such as skin cancer. Skin cancer is a serious disease that can be fatal ana requires high treatment costs. It ranks thirds after cervical cancer and breast cancer in Indonesia, with causative factors including genetics and exposure to UV radiation. Early detection and proper diagnosis are essential to increase the chances of recovery, so skin cancer classification is necessary to avoid delays in treatment. Deep Learning methods, particularly Convolutional Neural Network (CNN), have been shown to provide significant result in image classification with high accuracy. VGG16 and DenseNet121 are two popular CNN architecture used in image classification. This study aims to compare the performance of skin cancer classification using VGG16 and DenseNet121. The result show that the DenseNet121 architecture provides higher accuracy compared to the VGG16 architecture, with 93% accuracy for train data and 79% for test data, while the VGG16 architecture achieves 80% accuracy for train data and 74% for test data. These results show that the DenseNet121 architecture is superior in skin cancer classification, providing important information for more accurate diagnosis
