This study evaluates Linear Interpolation, Polynomial, and Gaussian Models for predicting the Temperature Change Sub-Index in a Water Quality Index (WQI). Using a dataset from NSF-WQI, we propose a new formula based on polynomial and Gaussian approaches, offering improved accuracy over the traditional linear interpolation method for better water quality assessment. The Gaussian Model 1 emerged as the most accurate, with a 97.54% accuracy and a mean error of 2.46, outperforming the Cubic Polynomial and Fourth-Degree Polynomial Models, which achieved accuracies of 94.60% and 96.03%, respectively. The Gaussian Model's ability to capture peak characteristics and symmetrical declines makes it particularly effective for applications requiring precise water quality predictions. The integration of Gaussian Model 1 into IoT-enabled realtime monitoring systems presents significant potential, enabling continuous, accurate predictions critical for managing sensitive aquatic environments. However, the study acknowledges limitations, including the narrow data range that may limit Model generalizability and the complexity of higher-degree polynomial models, which could reduce practical applicability. Future research should focus on validating these Models across more diverse datasets, exploring hybrid Models that combine Gaussian and polynomial strengths, and enhancing computational efficiency to support broader realtime applications.

The Water Quality Index (WQI) has been developed as a tool to condense complex water quality data into a single, easily interpretable value. Standard WQI calculations typically incorporate parameters such as pH, temperature, dissolved oxygen (DO), turbidity, and total dissolved solids (TDS). This study provides a comprehensive review of existing literature, focusing on the application of physicochemical and biological sensors in water quality monitoring. The findings indicate that biological sensors, particularly those used for detecting contaminants such as Escherichia coli (E. coli), are often unsuitable for real-time monitoring due to inherent technical limitations. In contrast, the integration of Internet of Things (IoT) technologies significantly enhances the capability for real-time monitoring, enabling the prompt detection of variations in water quality. The study suggests that future research should prioritize the development of a WQI that incorporates the selected parameters identified in this research, ensuring that IoT-based water quality monitoring systems operate with greater efficiency and reliability. Such advancements are essential for supporting the sustainable management of water resources and enhancing environmental protection efforts.

Diantaranya dengan melakukan promosi. Ketepatan promosi dapat dipelajari dari database sebuah perusahaan ritel utamanya pola belanja pada produk yang biasa dibeli bersamaan. Informasi tentang pola belanja pelanggan yang tidak akurat menyebabkan kebijakan promosi tidak tepat dan efisien.Salah satu upaya lazim untuk memperoleh dan menggali pola belanja pelanggan adalah menggunakan data mining yang dikenal sebagai Knowledge Discovery in Database (KDD). Pendekatan yang biasa digunakan adalah asosiasi. Permasalahannya aturan asosiasi cenderung mengabaikan dataset yang besar. Untuk mengatasi hal tersebut dilakukan klasifikasi barang yang dibeli dan tidak dibeli bersamaan. Algoritma Self Organizing Map (SOM) dan K-Medoids cocok untuk diterapkan dalam mengcluster dataset besar. Penelitian ini menguji kevalidan dan kecepatan algortima Self Organizing Map (SOM) dan K-Medoids jika dikombinasi dengan Frequent Pattern-Growth (FP-Growth).

Traditional methods, which typically involve in-situ sample retrieval followed by laboratory assessments, have been perceived as laborious and time-consuming. Herein, a state-of-theart, open-source framework is introduced, leveraging the potent synergy of the Internet of Things (IoT) and cloud computing for real-time water quality evaluations. Commercially accessible sensors were utilized for the instantaneous acquisition and interpretation of essential water quality parameters: pH, temperature, total dissolved solids (TDS), and turbidity. Accuracies of 98.54%, 96.85%, and 98.10% were obtained for temperature, pH, and TDS measurements, respectively, based on chosen accuracy metrics. The resilience of the proposed system was ascertained through a comprehensive study at the Troso River, Indonesia. During this evaluation, 4,833 data entries were amassed within a two-hour period. Outcomes from this research, elucidated in the subsequent sections, underscore the proficiency of the system in real-time water quality surveillance. This investigation augments the extant literature, underscoring the transformative role of cloud computing in facilitating instantaneous raw data collection for water quality assessment endeavors.

The quality of X-ray image results is represented in the X-ray image contrast range. Correction of contrast ranges can be done computationally to improve X-ray image quality. From the problem then needed a method to improve result of X-ray image quality. In this research proposed OTSU thresholding modified into the Contrast-Limited Adaptive Histogram Equalization algorithm as a substitute for cliplimit value to improve the contrast quality of X-ray Image results which will then be measured with Mean Square Error to find out how much error value is generated.
