Abstract

Kre’ Alang is a traditional woven fabric unique to Sumbawa that holds high cultural and economic value, beauty, and uniqueness, attracting many people. The competition between authentic Kre’ Alang from Sumbawa and similar imitation products that are cheaper poses a threat to the existence of authentic Kre’ Alang. One of the factors causing authentic Kre’ Alang from Sumbawa to struggle against imitation products is the limited marketing media available. UMKM players in Sumbawa still rely on word-of-mouth marketing to promote Kre’ Alang products, which limits their ability to reach a broader market. This has resulted in the original Kre’ Alang from Sumbawa not being able to fully realize its market potential. The e-catalog is a solution that can help reach a wider market. The e-catalog provides complete and detailed information about products to consumers, making it easier to choose and purchase the desired products. Research conducted in 2023 by a team of researchers shows that technology orientation is an important factor in enhancing product competitiveness. Technology orientation refers to the level of use of the latest technology in product marketing. The use of technology such as e-catalogs can help MSME actors like Kre’ Alang to market their products widely, thereby increasing competitiveness and opportunities to reach the market. The method for creating the Kre Alang e-Catalog prototype model uses a flexible prototyping method that is quick and dynamic in its development.

Abstract

Egg quality inspection before distribution is crucial to ensure edibility and prevent complaints from retailers or distributors. Fadillah Jaya Sumbawa (FJS) Poultry Farm still uses a manual method for this process, which takes a long time and risks data recording errors. This study aims to design a monitoring and control prototype based on the Internet of Things (IoT) to detect egg quality. The system utilizes a light-dependent resistor (LDR) sensor to analyze the intensity of light passing through the eggshell and transmits the data to an IoT platform for easier monitoring. Additionally, a control mechanism is integrated to support the inspection process. The research method follows the Software Development Life Cycle (SDLC) approach using the prototype model. The results indicate that the designed prototype can assist poultry farms in reducing data recording errors and minimizing complaints from retailers or distributors.

The curriculum is to develop a number of study programs at UTS, adapted to the developments and demands of today's world of work. This research was conducted to determine the level of satisfaction of Stakeholders on the quality of graduates. Research is using a descriptive method with a quantitative approach. Analysis data method uses the Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA). Respondents in this study were graduate users (Stakeholders) with a total of 100 respondents. The results of this study, that the quality of graduates from UTS is very good, even though they work not in their field of expertise (non-academic). Even though the quality of the graduates is in the category very good, there are several items/attributes that need to considere. In meeting the satisfaction of Stakeholders, namely Point number 9 regarding the ability of graduates to write activity reports. , such as research and projects. The second point, number 14 is the ability of graduates to use technology related to their field of science. Item number 15 is the graduate's ability to use computers.

Abstract

Customer churn represents one of the most critical challenges in the telecommunications industry, as the cost of acquiring new customers significantly outweighs the expense of retaining existing ones. High churn rates directly impact corporate revenue stability and market competitiveness, necessitating the development of precise predictive systems. This study presents a comprehensive comparative analysis of two prominent ensemble learning algorithms, Random Forest (RF) and Extreme Gradient Boosting (XGBoost), to establish a robust predictive framework for identifying potential churners using a large-scale Telco subscriber dataset. To ensure the reliability and scientific validity of the comparison, the research methodology incorporates the Synthetic Minority Over-sampling Technique (SMOTE) to rigorously address the inherent class imbalance within the dataset, ensuring that the minority churn class is adequately represented during the training phase to avoid model bias. Furthermore, a systematic hyperparameter tuning process was executed via GridSearchCV, exploring multiple combinations of estimators, depth, and learning rates to identify the optimal configurations for both algorithms. The experimental results reveal that while both models are highly effective, Random Forest slightly outperformed XGBoost, achieving an overall accuracy of 77.54% and a balanced F1-score of 0.616, compared to XGBoost’s accuracy of 76.54% and F1-score of 0.605. Notably, although both models demonstrated an identical recall rate of 67.64%, Random Forest exhibited superior precision (56.47% vs. 54.76%), which is vital for minimizing false positives and ensuring cost-effective retention campaigns. Feature importance analysis, conducted through Gini impurity and gain metrics, further identified tenure, total charges, and month-to-month contract types as the primary drivers of customer attrition. This study concludes that an optimized Random Forest model provides a more stable and accurate framework for telecommunication providers to proactively mitigate customer turnover. The findings offer valuable business intelligence, allowing stakeholders to transition from reactive measures to proactive, data-driven loyalty programs that enhance long-term business sustainability.
