The best test results are in fold-3, which is getting an accuracy rate of 95%. Evaluation of the k-Nearest Neighbor model with k-Fold Cross Validation can get a good machine learning model and the Analytic Hierarchy Process as a feature selection also gets optimal results and can reduce the performance of the k-Nearest Neighbor method because it only uses features that have been selected based on the level of importance for decision making.</p> Zoelkarnain Rinanda Tembusai Herman Mawengkang Muhammad Zarlis Copyright (c) 2021 Zoelkarnain Rinanda Tembusai, Herman Mawengkang, Muhammad Zarlis https://creativecommons.org/licenses/by-sa/4.0 2021-01-11 2021-01-11 2 1 1 8 10.25008/ijadis.v2i1.1204 Multi-Attribute Decision Making using Hybrid Approach based on Benefit-Cost Model for Sustainable Fashion http://ijadis.org/index.php/IJADIS/article/view/multi-attribute-decision-making-using-hybrid-approach-based-on-b <p>Multi-Attribute Decision Making (MADM) is used to select the best alternative from multi-alternatives based on multi-attribute (fashion material) and multi-criteria (sustainable fashion). Multi-alternatives are cotton, linen, silk, wool, acrylic, nylon, polyester, rayon, spandex, and mixed. Multi-attributes are material, texture, color, characteristic, comfort, and wearability. Multi-criteria are material fiber, smooth texture, faded color, elastic clothing, useful long, chilly and comfortable. Hybrid approaches and optimal solutions are needed to determine the best choice in decision making for both producers and consumers. The hybrid approach in MADM used is Simple Multi-Attribute Rating (SMART), Multi-Factor Evaluation Process (MFEP), Multi-Object Optimization based on Ratio Analysis (MOORA), Simple Additive Weighting (SAW), and Weighted Product (WP). SMART and MFEP are based on the Non-Benefit Cost Model while MOORA, SAW, and WP are based on a Benefit-Cost Model. The experimental results show that the SMART model with the best alternative is the rayon with the highest value (2.8333). The selection of the MFEP Model with the best alternative is rayon with the highest value (2.8330). The choice of MOORA model with the best alternative is rayon with the highest value (0.2595). The selection of the SAW Model with the best alternative is rayon with the highest value (0.8932). The selection of the WP Model with the best alternative is rayon with the highest value (0.1285). MADM using SMART, MFEP, MOORA, SAW, and WP for sustainable fashion yields the best alternative for consumption and production for the middle-class population in Indonesia.</p> Adriyendi Adriyendi Yeni Melia Copyright (c) 2021 Adriyendi Adriyendi, Yeni Melia https://creativecommons.org/licenses/by-sa/4.0 2021-01-11 2021-01-11 2 1 9 24 10.25008/ijadis.v2i1.1200 Self-Diagnosis of Web-Based Pregnancy and Childbirth Disorders Using Forward Chaining Methods http://ijadis.org/index.php/IJADIS/article/view/self-diagnosis-of-web-based-pregnancy-and-childbirth-disorders-u <p>The high mortality rate for pregnant women and childbirth in Bali, Indonesia, is caused by a lack of initial diagnosis of the diseases and complaints experienced by pregnant women during pregnancy, as well as a lack of health medical personnel scattered throughout Bali, to be able to provide optimal health services. It is necessary to have an online information system that helps pregnant women to be able to independently and online diagnose diseases, complaints, and symptoms experienced during pregnancy. The system must be able to be accessed anytime and anywhere, with high reliability and availability, and provide fast diagnostic results. Focus of this research is design and implementation of an Information System for Diagnosis of Pregnancy Disorders Based on Cloud Computing based on Forward Chaining Method, using Design Science Research Methodology (DSRM) and tested using the Technology Acceptance Model (TAM) method. The application is placed on the Hybrid Cloud. The results of this research, can help pregnant women in diagnosing diseases and complaints online, to reduce the mortality rate for pregnant women and giving birth.</p> I Putu Agus Eka Pratama Copyright (c) 2021 I Putu Agus Eka Pratama https://creativecommons.org/licenses/by-sa/4.0 2021-01-11 2021-01-11 2 1 25 35 10.25008/ijadis.v2i1.1198 Sentiment Analysis Approach for Analyzing iPhone Release using Support Vector Machine http://ijadis.org/index.php/IJADIS/article/view/sentiment-analysis-approach-for-analyzing-iphone-release-using-s <p>Sentiment analysis is a process of understanding, extracting, and processing textual data automatically to get sentiment information contained in a comment sentence on Twitter. Sentiment analysis needs to be done because the use of social media in society is increasing so that it affects the development of public opinion. Therefore, it can be used to analyze public opinion by applying data science, one of which is Natural Language Processing (NLP) and Text Mining or also known as text analytics. The stages of the overall method used in this study are to do text mining on the Twitter site regarding iPhone Release with methods of scraping, labeling, preprocessing (case folding, tokenization, filtering), TF-IDF, and classification of sentiments using the Support Vector Machine. The Support Vector Machine is widely used as a baseline in text-related tasks with satisfactory results, on several evaluation matrices such as accuracy, precision, recall, and F1 score yielding 89.21%, 92.43%, 95.53%, and 93.95, respectively.</p> Wasim Bourequat Hassan Mourad Copyright (c) 2021 Wasim Bourequat, Hassan Mourad https://creativecommons.org/licenses/by-sa/4.0 2021-04-30 2021-04-30 2 1 36 44 10.25008/ijadis.v2i1.1216 Greedy, A-Star, and Dijkstra’s Algorithms in Finding Shortest Path http://ijadis.org/index.php/IJADIS/article/view/greedy-a-star-and-dijkstras-algorithms-in-finding-shortest-path <p>The problem of finding the shortest path from a path or graph has been quite widely discussed. There are also many algorithms that are the solution to this problem. The purpose of this study is to analyze the Greedy, A-Star, and Dijkstra algorithms in the process of finding the shortest path. The author wants to compare the effectiveness of the three algorithms in the process of finding the shortest path in a path or graph. From the results of the research conducted, the author can conclude that the Greedy, A-Star, and Dijkstra algorithms can be a solution in determining the shortest path in a path or graph with different results. The Greedy algorithm is fast in finding solutions but tends not to find the optimal solution. While the A-Star algorithm tends to be better than the Greedy algorithm, but the path or graph must have complex data. Meanwhile, Dijkstra's algorithm in this case is better than the other two algorithms because it always gets optimal results.</p> Muhammad Rhifky Wayahdi Subhan Hafiz Nanda Ginting Dinur Syahputra Copyright (c) 2021 Muhammad Rhifky Wayahdi, Subhan Hafiz Nanda Ginting, Dinur Syahputra https://creativecommons.org/licenses/by-sa/4.0 2021-02-01 2021-02-01 2 1 45 52 10.25008/ijadis.v2i1.1206 Features Selection for Entity Resolution in Prostitution on Twitter http://ijadis.org/index.php/IJADIS/article/view/features-selection-for-entity-resolution-in-prostitution-on-twit <p>Entity resolution is the process of determining whether two references to real-world objects refer to the same or different purposes.
