Abstract
Kepuasan mahasiswa/i terhadap fasilitas atau layanan universitas memerlukan
analisis yang mendalam untuk memastikan peningkatan fasilitas atau layanan yang
tidak memuaskan dan pertahankan fasilitas atau layanan yang memuaskan.
Penelitian ini dilakukan dengan tujuan menganalisis sentimen survei kepuasan
mahasiswa menggunakan metode Natural Language Processing (NLP). Data
survei yang dikumpulkan tahun 2022 hingga 2024, dianalisis menggunakan dua
pendekatan utama: Naive Bayes (NB) dengan n-gram (n = 1,2,3) menggunakan
metode ekstraksi fitur Term Frequency-Inverse Document Frequency (TF-IDF)
dan Bag of Words (BoW), dan Bidirectional Encoder Representations from
Transformers (BERT). Hasil analisis menunjukkan bahwa performa BERT
menunjukkan akurasi prediksi sentimen yang lebih tinggi dibandingkan NB,
dengan nilai F1-score sebesar 0.776978. Penelitian ini juga mengidentifikasi kata
kunci, baik sentimen positif, maupun negatif. Kata kunci tersebut kemudian akan
dianalisis dalam 11 kategori fasilitas atau layanan untuk memberikan wawasan
yang lebih terpusat mengenai aspek yang perlu dipertahankan dan ditingkatkan.
Penelitian ini menyimpulkan bahwa analisis sentimen memberikan kontribusi yang
penting bagi universitas dalam mengevaluasi dan meningkatkan kualitas fasilitas
atau layanan sesuai preferensi mahasiswa/i secara keseluruhan. / Student satisfaction with university facilities and services requires in-depth
analysis to ensure improvements in unsatisfactory facilities or services while
maintaining those that meet expectations. This study aims to analyze sentiment in
student satisfaction surveys using Natural Language Processing (NLP) methods.
Survey data collected from 2022 to 2024 were analyzed using two main
approaches: Naive Bayes (NB) with n-grams (n = 1,2,3) employing feature
extraction methods such as Term Frequency-Inverse Document Frequency
(TF-IDF) and Bag of Words (BoW), and Bidirectional Encoder Representations
from Transformers (BERT). The analysis results indicate that BERT outperforms
NBin terms of sentiment prediction accuracy, with an F1-score of 0.776978. This
study also identified keywords for both positive and negative sentiments. These
keywords were then analyzed across 11 categories of facilities and services to
provide focused insights into aspects that need to be maintained or improved. This
study concludes that sentiment analysis provides significant contributions to
universities in evaluating and enhancing the quality of facilities and services
according to student preferences.
