Abstract

The landfill is a place where waste reaches the last stage in its management since it began to arise in the source, collection, transportation, processing, and disposal. Muara Fajar landfill is one of the landfills in Pekanbaru City whose garbage increase exceeds the capacity of waste storage land so that it can produce 800 tons of garbage per day in dry weather and 1000 tons per day in rainy weather. The problem caused by the management of the Muara Fajar landfill is air pollution due to the process of decomposing organic matter anaerobically which has the potential to cause unpleasant odors and health problems. With this problem, a system was built to monitor and detect hazardous gases in landfill, namely H2S gas using MQ-136 sensors, CH4 gas by MQ-4 sensors, and CO2 and NH3 gases using MQ-135 sensors. This system is implemented with the IoT protocol, MQTT Broker to receive and send monitoring data to the Website with notifications from the telegram web application. Based on testing the value of ppm in CO2 Gas with a danger status of 1000-4000 ppm, H2S Gas is 10-400 ppm, NH3 is included in the status of be careful which is 0.03 ppm, and CH4 with normal status because the value of ppm levels is below 10000 ppm

Abstract

Cryptography is the study of how to transform data or information into a form that is unreadable by others, thus ensuring the security of the data. Based on a questionnaire conducted among students of Politeknik Caltex Riau (PCR) who have studied classical cryptography, the Vigenere Cipher and Affine Cipher were found to be the most difficult algorithms to understand. This research aims to investigate the improvement in students' knowledge of classical cryptography through interactive 3D simulations. The experiment was conducted on 30 PCR students by comparing two learning groups: a control group (using textbooks) and an experimental group (using 3D simulations). The results showed that the average post-test score for the control group was 67.33 point, while the experimental group achieved an average score of 83.33 point. Thus, learning with 3D simulation media can serve as an effective alternative medium, with a confidence level of 95%, to enhance students' understanding of classical cryptography. Meanwhile, the satisfaction level indicates that 86.75% of students are satisfied with learning through interactive 3D simulation media. This indicates that the use of classical cryptography learning media through 3D simulations provides a significant improvement in student learning outcomes.

Abstract

Purpose: The purpose of this study is to increase the accuracy of the model used for prediabetes prediction. This study integrates Principal Component Analysis (PCA) for reducing the dimension of data with Extreme Gradient Boosting (XGBoost). The study contributes to providing a new alternative for prediabetes prediction in patients by reducing the complexity of the dataset with the aim of increasing the accuracy of the obtained model. PCA and XGBoost identify the best features that have the highest correlation with prediabetes so that they are expected to produce a better predictive model. Methods: This study utilizes published data sourced from the UCI Machine Learning Repository consisting of 520 records, 16 attributes and 1 label class. The dataset is data collected through direct questionnaires from patients in Sylhet, Bangladesh at the Sylhet Diabetes Hospital. The research method in this study consists of several stages, namely: Data Collection, Data Preprocessing, Dimension Reduction using PCA to reduce the complexity of dimensions in the dataset, Modeling using XGBoost to identify patterns used to predict prediabetes, and Model evaluation used to measure the performance of the resulting model using evaluation metrics such as accuracy, recall, precision and F1-Score. Result: The current study utilizes XGBoost with Principal Component Analysis for feature selection, resulting in 12 features and a model accuracy of 97.44. Novelty: The study's originality lies in applying PCA as a preprocessing step to enhance the performance of machine learning models by reducing data dimensionality and focusing on the most critical features. By demonstrating how PCA can improve the efficiency and accuracy of prediabetes prediction models, this research provides valuable insights to inform future studies and contribute to the development of more effective diagnostic tools for early detection and prevention of prediabetes.

Abstract

SMK Taruna Persada Dumai is one of the vocational schools that participate in the SMK Center of Excellence program. This program focuses on developing specific skill competencies for SMK students. Competency development is prioritized on competencies that are aligned with the business world, industrial world, and world of work. Based on the evaluation of the previous year's Community service activities, the SMK Taruna Persada Dumai asked to continue the activity to increase its students’ competencies. The competency that will be taught in the 2022 Community service PSTRK is an introduction to the field of IoT which is currently developing. PSTRK implements Student-Centered Learning (SCL) to increase the competency of SMK students in monitoring IoT projects through the Blynk platform. Community service was held on September 6, 2022, from 9.00 am to 14.00 pm. This activity was attended by 20 students from the Department of Computer Network Engineering, SMKS Taruna Persada Dumai City. The given SCL module consists of 5 parts. The first part focuses on the small group discussion learning model in the introduction of processors, actuators, and sensors. Then, in the second part, the students simulated the LED and ESP32 circuits using the wokwi.com simulator. The third part is followed by a case study model of the LED series and NodeMCU 8266. Students’ enthusiasm for independent learning makes this third part take a long time. So, the fourth part in the form of colorful light control role-plays in the form of LED control via Blynk, and the fifth part in the form of a discovery learning model for reading DHT11 sensor data did not have time to work on it. As a solution, the Community service team left two sets of learning modules for students to work on independently later. At the end of the lesson, feedback from students was collected and the results showed their satisfaction with the material provided, the way it was presented, the quality of the modules, and the suitability of the material. The students also hope to be included in other Community service programs with different materials.
