Abstract

This study developed a predictive model based on Random Forest algorithm to predict survival rate of Vannamei shrimp using five water quality parameters: dissolved oxygen (DO), temperature, pH, salinity, and Total Dissolved Solids (TDS). The model was trained on this data and evaluated using Mean Squared Error (MSE) and R² Score, with an MSE of 0.71 and R² Score of 1.00. Endpoint testing was conducted using Postman to verify the model response, with output parameters including anomaly_detected, recommendation, and survival rate. The model successfully detected anomalous conditions and provided recommendations according to the detected water quality parameters. Test results showed that DO and salinity had the greatest influence on survival rate, while pH, TDS, and temperature made moderate contributions.

Abstract

The textile industry is a significant contributor to environmental pollution due to its wastewater, which contains hazardous substances such as dyes, heavy metals, and chemicals that can severely harm aquatic ecosystems. Effective management of this wastewater is crucial to mitigate its environmental impact. This study focuses on classifying industrial liquid waste data using the K-medoids clustering method, chosen for its robustness to noise and outliers compared to K-means. To address challenges in wastewater data processing, such as missing values and varying data scales, two approaches are compared: replacing missing values with zero and K-nearest neighbors (KNN) imputation, alongside Z-score normalization for data uniformity. The clustering quality is evaluated using the Davies-Bouldin index (DBI) for cluster variations of k=2, 3, 4, and 5. The results show that the best clustering quality is achieved at k=2, with the smallest DBI values obtained using KNN imputation (0.139) and zero replacement (0.149). The superior performance of KNN imputation highlights its effectiveness in handling missing data. These findings provide valuable insights into the characteristics of textile industry wastewater pollution, offering a robust framework for effective wastewater management. The study concludes with practical recommendations for policymakers and industry stakeholders to adopt advanced data-driven approaches for sustainable wastewater treatment strategies.

Abstract

Usaha Karya Bamboo Weaving Center is a bamboo weaving craft institution located in RT 02 RW 04 Dusun Bokol Kulon, Banjarwaru Village. It is managed independently by Hadi Tuslam Ranantika together with the community. This group started the business with 14 members who were tasked with making bamboo weaving crafts based on local wisdom, such as bags, clothes, baskets, bamboo boxes, flower vases, tissue holders, and other accessories. The biggest problem partners face is that the large number of orders cannot be fulfilled due to the limited availability of raw bamboo weaving materials. This is because they still rely on the conventional bamboo weaving process, which is labor-intensive and requires limited human resources to prepare the weaving materials. The purpose of this activity is to address the poor management system, which causes low efficiency in operations, quality control, and hinders long-term planning. Community service activities, including the application of bamboo weaving machine technology and the creation of a product sales system website for the bamboo weaving center in Banjarwaru Village, have helped increase the productivity and sales of partner products. The production results from the shredding machine enable the preparation of material requirements for 60 products per day, thereby exceeding the demand for raw materials by 50 products per day.

Abstract

Crime is a phenomenon that significantly impacts society, necessitating mapping efforts that can be utilized for further analysis. Clustering, as a data analysis technique, groups objects based on similarities or differences in their characteristics. This approach enhances the understanding of data by identifying patterns and relationships between criminal events, such as crime type, time, and location. By clustering crime data based on similar characteristics, authorities can make more effective and efficient decisions in crime prevention and control. However, selecting too many attributes can negatively affect clustering performance. To address this issue, this study applies Information Gain reduction to reduce data dimensionality by eliminating attributes with low informational contribution. Additionally, three clustering methods K-Medoid, K-Means, and X-Means are compared to evaluate their performance. The concept of Information Gain is also integrated to optimize cluster formation, measuring how much an attribute contributes to distinguishing objects within a cluster. By leveraging Information Gain, this study aims to identify the most relevant and influential attributes in forming clusters that accurately represent crime data characteristics. Furthermore, the number of clusters generated is evaluated using the Davies-Bouldin Index (DBI). The results indicate that the K-Means algorithm outperforms the other two methods, achieving the best clustering quality with an optimal number of clusters (k = 6) and the lowest DBI value.

Abstract

The use of Learning Management Systems (LMS) in lectures is increasing, but student motivation to learn often poses a challenge. This study aims to examine the effect of gamification in LMS on student motivation to learn and to analyze the relationship between students' perceptions of gamification and their motivation levels. The study uses a quantitative design with measurements taken before and after the implementation of gamification, as well as correlation analysis to examine the relationship between variables. The results show that there is no significant difference between motivation before and after the implementation of gamification. However, perceptions of gamification are positively related to autonomy, connectedness, and achievement, which contribute to increased learning motivation. These findings indicate that gamification has an indirect effect through the reinforcement of psychological aspects that support intrinsic motivation.
