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

This research explores and compares the performance of two popular load testing tools, namely Gatling and Apache JMeter, with a focus on API performance testing. The rapid growth in web and mobile application development highlights the urgent need to ensure optimal API performance. This research was conducted to provide in-depth insight into the advantages and disadvantages of these two testing tools through the use of similar testing scenarios. The experimental method involves implementing test scenarios that include load variations and high demands on both devices. The main parameters observed include API response time, throughput, and latency. In-depth analysis was carried out on the data obtained to evaluate the reliability and efficiency of each tool. The results of this research provide a comprehensive understanding of the performance of Gatling and Apache JMeter in the context of API performance testing. These findings can provide practical guidance for software developers and testing practitioners in selecting load testing tools that suit their project needs. Recommendations for future research include expanding exploration of other load testing tools, comparison with more complex test scenarios, and integration with performance monitoring tools for more holistic analysis. Thus, this research is expected to make a significant contribution to the understanding and selection of effective load testing tools in web and mobile application development.

Abstract

The Kedawung Village Office is one of the government institutions at the village level. They will collect data on goods and assets. However, the current data collection process has not been running optimally, which results in obstacles like the fact that inventory reports of goods and assets owned by the village are not well recorded and there is no recording of reports when there is damage to goods. This research aims to create a prototype system to facilitate the Head of General Affairs and Planning, the Village Secretary, and the Village Head in recording goods and reports on damage to goods. The system was developed using the System Development Life Cycle (SDLC) method and the prototyping method. After testing the system using the black box method, the system is tested with several scenarios, and the system can perform all its functions properly. This system can facilitate the Head of General Affairs and Planning in collecting data on goods quickly and precisely, as well as the Village Secretary and Village Head in verifying the condition of goods.Kantor Desa Kedawung sebagai salah satu lembaga pemerintahan di tingkat desa tidak lepas dari pendataan barang maupun aset. Namun, proses pendataan saat ini belum berjalan secara optimal dikarenakan masih dilakukan secara konvensional yang mengakibatkan kendala seperti data laporan inventaris barang dan aset yang dimiliki oleh desa tidak terdata dengan baik dan tidak adanya pencatatan laporan ketika terjadi kerusakan barang. Penelitian ini bertujuan membuat purwarupa sistem untuk mempermudah Kepala Urusan Umum dan Perencanaan, Sekretaris Desa, serta Kepala Desa dalam pencatatan barang serta laporan kerusakan barang. Sistem dikembangkan menggunakan metode System Development Life Cycle (SDLC) menggunakan metode prototyping. Setelah dilakukan pengujian sistem menggunakan metode blackbox, sistem diuji dengan beberapa skenario dan sistem dapat menjalankan semua fungsinya dengan baik. Sistem ini dapat memudahkan Kepala Urusan Umum dan Perencanaan dalam melakukan pendataan barang dengan cepat dan tepat serta Sekretaris Desa dan Kepala Desa dalam melakukan verifikasi kondisi barang
