This study proposes a way to verify these problem sets. The main contribution of this paper is a method to verify a set of most frequent problems in waste disposal practices previously identified through a survey questionnaire, using Google Earth visualization and the Apriori algorithm. Google Earth is used to pinpoint the geographical locations of existing waste bins, illegal landfills, and people's houses. The distance between the waste bins and the residents' houses, sites of waste disposal by burning, and sites of waste disposal by dumping are then analyzed as a combination of the problems of waste disposal practices. Support, Confidence, multiplication between Support and Confidence, and lift ratio values are then calculated to obtain a combination of the most frequent problems sets. Next, the support value in the Apriori algorithm is compared with the FP-Growth method using Rapidminer. Results obtain support and thus verify data previously obtained from the survey. For a 2-itemset problem and a minimum support value of 0.1, 33% accuracy is obtained, while a 3-itemset problem returns 99% accuracy. We show that our method is useful in verifying data previously obtained from other sources.","PeriodicalId":189541,"journal":{"name":"2021 Sixth International Conference on Informatics and Computing (ICIC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122622088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we designed a Multiple Criteria Decision-Making (MCDM) model to apply to this decision-making process. The model integrated the AHP method with the VIKOR method. First, based on the professional decision-maker judgment in evaluating a pairwise criteria comparison, the AHP determined the acceptable criteria weights automatically, and the VIKOR then utilized them to rank alternatives based on the values of utility and regret measures. After checking the acceptability advantage and stability in decision-making, the results showed that alternative U5 and U8 were the compromise solutions representing the closeness to the ideal solution.

Learning style is one of the most important factors in the E-learning environment because it can help the system to effectively personalize the learning process of students according to their learning style. Previously, to detect student learning styles by asking students to fill out questionnaires. However, there are problems with this static technique. One of these problems is the lack of students' self-awareness of their learning preferences. In addition, almost all students feel bored when asked to fill out a questionnaire. This research determined the learning style based on the Felder and Silverman Learning Style. This determination process is carried out using student activity data on a pure Moodle learning management system (LMS). The process begins with processing based on the literature to get a vector combination of learning styles. Student activity data is processed to produce data that only contains activities that are included in the selected features. The results of both are combined as input to the clustering process. This research applies the modified K-Means Clustering algorithm. Modifications were made using the learning style combination vector as the initial centroid. The k value used in this study was 8 which came from 8 combinations of learning styles from 3 dimensions used in this study. This is different from the combination of learning styles in FSLSM which has 16 combinations of learning styles originating from 4 dimensions of learning styles. This difference is caused by student activity data that only supports 3 dimensions of learning style.","PeriodicalId":189541,"journal":{"name":"2021 Sixth International Conference on Informatics and Computing (ICIC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121225069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
