Abstract

The increasingly competitive business environment required companies to make objective decisions, particularly in determining the feasibility of outlet contract extensions. PT Nitro Pratama Indonesia previously conducted this process manually, which often led to inconsistent decisions. This study aimed to develop a web-based decision support system to evaluate outlet cooperation systematically. A combination of Fuzzy Analytical Hierarchy Process (Fuzzy AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was applied. Fuzzy AHP was used to determine the weight of criteria under uncertain conditions, while TOPSIS was used to rank alternatives based on their proximity to the ideal solution. The study involved 50 active outlets located in Surabaya and Solo branches. The final criteria weights obtained were Outlet Revenue (0.33), Rental Cost (0.26), Outlet Location (0.16), Accessibility (0.11), Competitiveness (0.08), and Operational Cost (0.06). The ranking process generated objective recommendations that were consistent with manual calculations. Functional testing using Black Box Testing indicated that all system features operated properly. The system proved effective and relevant in supporting accurate and efficient decision-making for outlet contract extensions.

Abstract

This study reviews the application of the Autoregressive Integrated Moving Average (ARIMA) method for exchange rate forecasting based on previous research. The review focuses on model characteristics, order selection, and forecasting accuracy. A Systematic Literature Review (SLR) was conducted on relevant articles published within the last five years. The findings indicate that ARIMA remains widely applied, particularly for short-term forecasting, with low-order models often providing the best performance. However, no single ARIMA model is universally applicable across different countries and conditions. The study concludes that ARIMA is effective as a baseline forecasting method but has limitations in capturing complex market dynamics.

Abstract

The increasing interest of the people of East Java in mountain hiking activities has created a need for digital solutions that can integrate information, preparation, and hiking safety. This study aims to design the user interface and user experience of a mobile-based mountain hiking application called Mountzy using the Design Thinking method. The stages applied include empathize, define, ideate, prototype, and test, with a focus on the needs of hikers in East Java. The design results are realized in the form of information architecture, wireframes, and high-fidelity prototypes that include key features such as Pantau Langit, Hiking Planning, Sewa Aja (equipment rental), and Community Forum. Usability testing was conducted using Maze and the System Usability Scale (SUS). The results show a Maze score of 83 and an average SUS score of 83.20, which fall into the excellent and acceptable categories. These results indicate that the Mountzy application has good usability and is feasible for further development.

Abstract

Frontend performance is a critical factor influencing website user experience, particularly in terms of page loading speed, visual stability, and rendering efficiency. This study aims to analyze the frontend performance of the community page on yayasanmangroveindonesia.com using the Core Web Vitals approach supported by two widely used automated testing tools, namely Google Lighthouse and GTmetrix. A descriptive quantitative method was employed by conducting performance testing three times on each tool, and the results were averaged to obtain more representative measurements. The evaluation focused on the metrics available in both tools, including Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) as the primary metrics, supported by First Contentful Paint (FCP), Total Blocking Time (TBT), Speed Index, and Time to Interactive (TTI). The results show that Google Lighthouse achieved a Performance Score of  95, with an average LCP of 2.77 seconds, CLS of 0.03, FCP of 0.97 seconds, TBT of 56.67 ms, and Speed Index of 1.23 seconds. Meanwhile, GTmetrix obtained a Performance Score of 99 and a Structure Score of 100, with an average LCP of 0.48 seconds, CLS of 0.06, FCP of 0.48 seconds, TBT of 5.33 ms, and TTI of 0.66 seconds. Overall, the website demonstrates good frontend performance, although the LCP value measured by Google Lighthouse slightly exceeds the recommended Core Web Vitals threshold, indicating opportunities for further optimization. The findings suggest that combining Google Lighthouse and GTmetrix provides a more comprehensive performance evaluation and can serve as a reference for implementing frontend optimization strategies to improve user experience.

Abstract

In the current era of modernization, almost everyone uses the internet to help solve their problems. Including security activities. Currently, many companies provide security services. There are also many companies or individuals who are or want to look for companies providing security services but they don't know where to look for these companies because of the lack of information. Therefore, to make it easier for security service seekers and security service providers, a design is needed that can be a solution to the problems of both parties. It is hoped that the required design will meet the needs because it must go through several stages of testing in accordance with standards and the needs of potential users. UI/UX analysis and design involved 10 respondents from two actors, namely companies providing security services and companies or individuals seeking security services. The final design was tested by the same 10 respondents with four types of testing. Testing is carried out repeatedly until respondents feel that the design meets the needs of potential users.
