Abstract

Penggunaan beton sudah semakin meluas dikarenakan beton memiliki kuat tekan yang lebih tinggi dibandingkan dengan bahan lain. Para ahli melakukan prediksi kuat tekan beton dengan kurang efektif karena masih menggunakan aturan dan rumus standar tertentu. Banyak penelitian dilakukan dengan beberapa metode namun belum diketahui metode mana yang terbaik. Penelitian ini melakukan komparasi antara metode Neural Network (NN), Support Vector Machine (SVM) dan Linear Regression (LR) dengan menggunakan dataset concrete compressive strength dan slump. Pada dataset concrete compressive strength dengan menggunakan metode NN didapatkan RMSE 5,667, dengan menggunakan metode SVM didapatkan RMSE 5,165 dan dengan metode LR didapatkan RMSE 10,501. Sementara pada dataset slump dengan menggunakan metode NN didapatkan RMSE 0,422, dengan menggunakan metode SVM didapatkan RMSE 2,778 dan dengan menggunakan metode LR didapatkan RMSE 2,65. Setelah hasil tersebut dikomparasi dengan perangkingan didapatkan total ranking NN adalah 3, total rangking SVM adalah 4, dan total rangking LR adalah 5. Dari total rangking tersebut dapat disimpulkan bahwa kinerja NN lebih baik dibanding SVM dan LR.

Abstract

Predicting student academic performance is one of the important applications in data mining in education. However, existing work is not enough to identify which factors will affect student performance. Information on academic values ​​or progress on student learning is not enough to be a factor in predicting student performance and helps students and educators to make improvements in learning and teaching. K-Nearest Neighbor is a simple method for classifying student performance, but K-Nearest Neighbor has problems in terms of high feature dimensions. To solve this problem, we need a method of selecting the Gini Index feature in reducing the high feature dimensions. Several experiments were conducted to obtain an optimal architecture and produce accurate classifications. The results of 10 experiments with values ​​of k (1 to 10) in the student performance dataset with the K-Nearest Neighbor method showed the highest average accuracy of 74.068 while the K-Nearest Neighbor and Gini Index methods showed the highest average accuracy of 76.516. From the results of these tests it can be concluded that the Gini Index is able to overcome the problem of high feature dimensions in K-Nearest Neighbor, so the application of the K-Nearest Neighbor and Gini Index can improve the accuracy of student performance classification better than using the K-Nearest Neighbor method.

Abstract

Abstract— Bloom's Taxonomy is a classification system that is used to define and distinguish the level of cognition (thinking, learning, and understanding) human diverse. The initial purpose in making taxonomy is focusing on three main domains of learning, which is cognitive, affective, and psychomotor. Nowadays, academics identify cognitive levels of Bloom of a question manually. However, only few academics that can be identify the cognitive level correctly, so most of them made a mistake to categorize questions. K-Nearest Neighbor (KNN) is a simple but effective method for categorization cognitive level questions on the Bloom's Taxonomy, however KNN has high dimention of text vector. In order to resolve these problems, the Information Gain (IG) method is needed to reduce dimention of text vector. Several experiments were conducted to obtain optimal architecture and produce an accurate classification. The results of 10 experiments on the Question Bank dataset with KNN obtained the biggest accuracy is 59,87% and the biggest kappa is 0,496. Then on KNN + IG obtained the biggest accuracy is 66,18% and the biggest kappa is 0,574 It can be concluded that the classification level cognitive questions on Bloom's taxonomy using KNN + IG method is more accurate than the KNN method only.Intisari— Taksonomi Bloom merupakan sistem klasifikasi yang digunakan untuk mendefinisikan dan membedakan tingkat kognisi (berpikir, belajar, dan memahami) manusia yang berbeda-beda. Tujuan awal dalam pembuatan taksonomi adalah memfokuskan pada tiga domain utama dari pembelajaran, yaitu kognitif, afektif, dan psikomotorik. Saat ini, kalangan akademisi mengidentifikasi tingkat kognitif Bloom sebuah pertanyaan secara manual. Namun, hanya sedikit akademisi yang dapat mengidentifikasi tingkat kognitif dengan benar, sehingga sebagian besar melakukan kesalahan mengkategorisasikan pertanyaan. K-Nearest Neighbor (KNN) merupakan metode sederhana namun efektif untuk kategorisasi tingkat kognitif soal pada taksonomi Bloom, namun KNN memiliki dimensi vektor yang besar. Untuk menyelesaikan masalah tersebut diperlukan metode Information Gain (IG) untuk mengurangi dimensi vektor teks. Beberapa eksperimen dilakukan untuk mendapatkan arsitektur yang optimal dan menghasilkan klasifikasi yang akurat. Hasil dari 10 eksperimen pada dataset Question Bank dengan KNN didapatkan akurasi terbesar adalah 59,97% dan kappa terbesar adalah 0,496. Kemudian pada KNN+IG didapatkan akurasi terbesar adalah 66,18% dan kappa terbesar adalah 0,574. Maka dapat disimpulkan klasifikasi tingkat kognitif soal pada taksonomi Bloom dengan menggunakan metode KNN+IG lebih akurat dibanding dengan metode KNN saja.Kata Kunci — Klasifikasi, Taksonomi Bloom, K-Nearest Neighboor, Information Gain

Abstract

The Faizul Haq Ta'lim Council is a non-formal institution that can make a considerable contribution to the development and progress of the State both before and after independence, as a potential means to convey Islamic da'wah and foster society. The students who study there acquire religious knowledge from the ustadz and ustadzah who teach at the Faizul Haq Ta'lim assembly based on the qura'an and sunnah. To further enrich the treasures and reference sources of religious knowledge, students also get it through internet media, namely with the help of search engines, but there are still many students who have not been able to use it optimally so that the search takes a long time. Therefore, we hold community service activities in the form of webinars to provide information and knowledge related to optimizing the use of search engines to assist students in finding the references they need and provide tips for faster and more effective searches. After holding community service in the form of counseling on search engine optimization for the students of the Faizul Haq Cisauk Ta'lim Council, the students can now use search engines like Google properly and correctly. They feel the difference from the previous one, it takes a long time and it is difficult to find the right reference and according to what they need. Now they can search for the references they need more effectively and efficiently.

Abstract

The process of receiving Covid-19 social assistance to residents who are recorded as social aid recipients in the RT.07 RW.10 Kp. Sukapura Jaya area is still uneven. The second problem is that there is no particular mathematical calculation to determine the value of the weight of the criteria, especially for residents who are recorded as receiving Covid-19 social aid in the RT.007 RW.10 Kp. Sukapura Jaya area. The gradual decline in social aid programs so that the number that falls does not match the data of social aid recipients. This caused a polemic for RT administrators in distributing social aid programs. The decline in social aid programs does not match the number of citizens recorded. It overcomes citizens who cause social jealousy—analyzing the problems experienced by the RT management in the distribution of Covid-19 social assistance, especially the RT.07 RW.10 Kp. Sukapura Jaya area to residents who are recorded as recipients. Selecting Covid-19 social assistance recipients, especially in the RT.07 RW.10 Kp. Sukapura Jaya area. So the application of methods as decision support is needed, and it is needed to help determine the weight of particular criteria for citizens who are recorded as more in need. This study proposes a decision support method using the Simple Additive Weighting (SAW) method, which is expected to help decision-making in solving problems for selecting Covid-19 social aid recipients in the RT.07 RW.10 Kp. Sukapura Jaya community. The purpose of the study is to select residents who are recorded to receive social aid who are more in need first will get Covid-19 social aid.
