Abstract

Dalam penelitian ini menggunakan metode Artificial Neural Network (ANN) dengan algoritma backpropagation untuk mengklasifikasi kesehatan rambut yang berisi faktor- faktor yang menyebabkan rambut rontok yang berkontribusi terhadap kebotakan. Data yang digunakan untuk pengujian ini terdiri dari 999 data dengan 13 atribut. Berdasarkan atribut-atribut tersebut 12 dijadikan Input dan 1 atribut (Hair Loss) akan dijadikan target dalam klasifikasi. Hasil klasifikasi kesehatan rambut menggunakan Backpropagation dengan Confusion matrix menghasilkan akurasi tertinggi yaitu 63.81%, dengan presisi untuk kelas 0 (No Hair Fall) yaitu 51.68%, presisi 1 (Hair Fall) yaitu 73.63%, dengan recall kelas 0 (No Hair Fall) yaitu 61.33%, dan recall kelas 1 (Hair Fall) yaitu 65.32% pada rasio data 80:20, dengan hyperparameter Learning Rate 0.001, neuron hidden 10 dan max epoch 2000 dengan arsitektur 12-10-1.

Abstract

Penelitian ini bertujuan untuk menggunakan Algoritma Backpropagation Neural Network dalam memprediksi tingkat kepuasan penumpang maskapai penerbangan. Langkah-langkah pengujian dilakukan dengan variasi rasio data 70:30, 80:20, dan 90:10 serta parameter seperti Learning Rate, Hidden Layer, dan Max_Epoch. Hasil penelitian menunjukkan bahwa Backpropagation Neural Network mampu melakukan prediksi dengan baik, dengan tingkat akurasi terbaik mencapai 99.82% pada rasio data 90:10. Struktur arsitektur terbaik terdiri dari 22 input layer, 20 Hidden Layer, dan 1 output layer, dengan iterasi/Max_Epoch sebanyak 1000 dan Learning Rate 0.01. Temuan ini menunjukkan potensi algoritma ini dalam meningkatkan pemahaman tentang kepuasan pelanggan dalam industri penerbangan.

Abstract

This study aims to compare the Inset Lexicon and MBERT sentiment labeling methods for analyzing sentiment related to the Danantara issue using a Support Vector Machine (SVM) with Linear, RBF, Polynomial, and Sigmoid kernels. The main issues in this study are the suboptimal sentiment labeling methods for Indonesian-language data that can accurately capture linguistic context, as well as the uncertainty regarding the best labeling method when combined with various TF-IDF-based SVM kernels. Model evaluation uses metrics such as Accuracy, Precision, Recall, F1-score, and Cross-validation (CV). The results show that the Inset Lexicon labeling method with a Linear kernel yields the highest Accuracy of 81% with a CV of 78%, Precision of 87%, and Recall of 92%. The RBF kernel achieved an Accuracy of 78% with a CV of 76%, followed by the Sigmoid kernel at 79% Accuracy with a CV of 76%, and the Polynomial kernel at 65% Accuracy with a CV of 65%. The highest F1-score for the negative class using the Linear kernel reached 89%. Meanwhile, in MBERT labeling, the highest accuracy was achieved by the RBF kernel at 72% with a CV of 71%, followed by the Linear kernel with an accuracy of 71%, then the Polynomial kernel with an accuracy of 68%, and the Sigmoid kernel with an accuracy of 67%. The highest F1-score was found in the negative class at 79% using the RBF kernel. Overall, the negative class showed the most consistent performance, while the neutral class had the lowest Recall and F1-score values for almost all kernel types. These findings confirm that an in-depth comparative analysis between lexicon-based and deep learning-based approaches demonstrates that methods such as the Inset Lexicon can deliver better and more stable performance on Indonesian-language data.
