Abstract

Media sosial X telah menjadi salah satu sarana utama bagi masyarakat dalam menyampaikan opini terhadap isu publik, termasuk kebijakan relokasi penduduk Pulau Rempang sebagai bagian dari Proyek Strategis Nasional (PSN). Permasalahan yang muncul adalah opini publik yang bersifat tidak terstruktur, beragam, dan tersebar luas sulit untuk diklasifikasikan secara manual dan objektif. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan sistem klasifikasi sentimen otomatis terhadap opini masyarakat dengan pendekatan kombinasi leksikal dan pembelajaran mesin. Sebanyak 1.000 tweet relevan dikumpulkan melalui proses crawling dan disaring menggunakan kriteria tertentu. Pelabelan sentimen dilakukan secara otomatis menggunakan InSet Lexicon, sedangkan representasi fitur teks dilakukan dengan metode TF-IDF. Algoritma Naïve Bayes Classifier digunakan sebagai model klasifikasi dan dievaluasi menggunakan confusion matrix, classification report, dan 10-fold cross-validation. Hasil evaluasi menunjukkan bahwa model mampu mengklasifikasikan sentimen pro dan kontra secara efektif, dengan akurasi tertinggi pada data uji sebesar 81,00% (rasio 90:10), dan akurasi validasi silang tertinggi sebesar 80,03% (rasio 80:20). Precision tertinggi diperoleh pada kelas pro (hingga 93%), sedangkan recall tertinggi pada kelas kontra (hingga 89%). Pendekatan ini terbukti efisien dan akurat untuk menganalisis opini publik berbasis media sosial, serta memiliki potensi untuk diterapkan pada isu-isu sosial lainnya yang relevan.

Abstract

Tracer study berperan penting dalam mengevaluasi kualitas layanan pendidikan berdasarkan pengalaman alumni. Analisis kepuasan alumni terhadap fasilitas pembelajaran umumnya masih terbatas pada statistik deskriptif, sehingga belum mampu mengungkap pola kepuasan secara tersegmentasi pada data berskala besar. Penelitian ini bertujuan untuk mengidentifikasi pola segmentasi kepuasan alumni terhadap fasilitas pembelajaran di Universitas Islam Negeri Sultan Syarif Kasim Riau (UIN Suska Riau) sebagai indikator penting dalam evaluasi kualitas layanan pendidikan. Metode yang digunakan adalah K-Means Clustering, diimplementasikan melalui tahapan Knowledge Discovery in Database (KDD) pada 6.508 data tracer study alumni S1 lulusan 2010–2023. Proses preprocessing mencakup normalisasi data numerik menggunakan Min-Max Scaling untuk menyamakan skala enam indikator kepuasan (Perpustakaan, Teknologi Informasi, Modul Belajar, Ruang Belajar, Laboratorium, dan Variasi Mata Kuliah), sehingga meminimalkan bias dalam perhitungan jarak Euclidean. Berdasarkan Elbow Method, diperoleh jumlah klaster optimal adalah K=3, dan kualitas pengelompokan divalidasi dengan nilai Davies-Bouldin Index (DBI) sebesar 0,874, mengonfirmasi stabilitas klaster yang terbentuk. Analisis menghasilkan tiga klaster berbeda: Klaster 0 (Tingkat Kepuasan Tinggi) yang dominan, Klaster 1 (Tingkat Kepuasan Rendah), dan Klaster 2 (Tingkat Kepuasan Sangat Tinggi). Hasil ini memberikan segmentasi kepuasan yang eksplisit sebagai dasar bagi universitas untuk merumuskan strategi peningkatan fasilitas secara terarah dan berkelanjutan.

Abstract

The instability of oil palm production often leads to discrepancies between production targets and actual outputs, thereby necessitating an accurate prediction model to support operational planning. This study aims to develop an oil palm production prediction model and to identify the most influential variables affecting production outcomes as a basis for data-driven decision-making. The model was developed using the Multiple Linear Regression method based on historical data from 2020–2024, consisting of 60 monthly observations with variables including number of trees, land area, rainfall, number of fruit bunches, and plant age. The research stages included data preprocessing, variable selection through testing several feature combinations, model development, and performance evaluation using the coefficient of determination (R²), Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Square Error (RMSE). The results indicate that the combination of number of trees, land area, number of fruit bunches, and plant age produced the best performance, with an R² value of 0.85 on the training data and 0.81 on the testing data. The MAE values were 125,307 kg and 176,984 kg, the MSE values were 28,870,838,455 kg² and 52,809,954,662 kg², and the RMSE values were 169,914 kg and 229,804 kg, respectively. Based on the regression coefficients, the number of fruit bunches was identified as the most dominant variable, with a coefficient value of 637,720 kg. The model was subsequently implemented using the Python Gradio library in the form of an interactive interface to support production planning effectiveness and minimize the risk of inaccurate decision-making in oil palm plantation management.

Abstract

Thyroid disease is a fairly common endocrine disorder that requires rapid and accurate diagnosis so that patients can receive appropriate treatment. This study was conducted to improve the system's ability to classify thyroid disease by utilizing data preprocessing techniques with RobustScaler and Random Over Sampling (ROS), as well as the Backpropagation Neural Network (BPNN) algorithm. The research dataset consisted of 3,771 patient data with 25 clinical attributes describing the condition and function of the thyroid. The data preprocessing process involved data selection, data cleaning, and data transformation using RobustScaler so that each feature had a more stable scale and was not affected by extreme values. The class imbalance problem was overcome using ROS so that the amount of data increased to 6,834 samples and the class distribution became more balanced. The Backpropagation Neural Network algorithm was applied in model training by testing various variations in the number of neurons in the hidden layer (38 and 49) and learning rate (0.01 and 0.001). Training was conducted for 5,000 and 10,000 epochs. Evaluation was performed using the 10-Fold Cross Validation method to obtain more consistent results. The results of the study show that the model is capable of achieving very high accuracy, up to 99.85%, on several parameters. The results show that proper data processing and appropriate parameter selection greatly affect model performance. Overall, the use of RobustScaler and ROS has been proven to significantly improve the accuracy of thyroid disease classification.

Abstract

Death in medical science is studied in a scientific discipline called tanatology. death is not only experienced by elderly people, but also can be experienced by young people, teenagers, or even babies. Death can be caused by various factors, namely, due to illness, old age, accidents, and so on. Based on information provided by the World Health Organization (WHO), there are five highest causes of death including ischemic heart disease, Alzheimer's, stroke, respiratory disorders, neonatal conditions. In this study, k-means is used to group causes of death in Indonesia based on the number of deaths that occur to determine the cases of death that have the most impact on the high mortality rate in Indonesia. Knowing what these death cases are will provide early preparation in anticipating the causes of death in Indonesia. The purpose of this study was to classify mortality rates based on the number of causes of death which were included in the low, medium, and high clusters by applying the K-Means method. In this study the authors used the K-Means clustering algorithm to classify death rates in data on causes of death in Indonesia from 2017-2021. The results of this study formed 3 clusters which were evaluated using the Davies Bouldin Index (DBI) in Rapidminer with a value of 0.259. Clustering results from a total of 21 cases obtained high, medium and low clusters. This cluster grouping was obtained according to the number of deaths per case, namely the first cluster (C0) was low with 17 cases, the second cluster (C1) was moderate with 3 cases and the third cluster (C2) was high with 1 case.

Abstract

Mushrooms are organisms that consist of several cells, contain spores, are eukaryotic (have a cell nucleus membrane), and do not have chlorophyll, so fungi depend on other organisms to get food. Mushrooms have very identical shapes, starting with size, shape, smell, and color. So it is difficult for ordinary people to differentiate between poisonous mushrooms and non-poisonous mushrooms. Mistakes in identifying mushrooms can have fatal consequences because they can cause poisoning when consuming mushrooms. Therefore, there is a need for education in classifying poisonous and non-poisonous mushrooms. By applying various classification algorithms, it can be determined which algorithm performs better. In previous research conducted by several researchers on classifying mushrooms, there were differences in the accuracy results for each algorithm. Therefore, this research will raise the question of how to measure or comparion algorithm performance in classification using the C4.5 algorithm and the Modified K-Nearest Neighbor (MKNN) algorithm. The results obtained by comparion the performance of the C4.5 algorithm and the Modified K-Nearest Neighbor (MKNN) algorithm in this research show that the C4.5 algorithm managed to obtain an accuracy level of 98.52%, precision of 98.55%, recall of 98.52%, and f1-score of 98.51%. In contrast, the Modified K-Nearest Neighbor (MKNN) algorithm using the value K=10 achieved an accuracy level of 96.62%, precision of 96.69%, recall of 96.62%, and f1-score value of 96.57%.
