Abstract

Political speeches are an important medium for conveying a country’s leader’s vision, mission, and policy directions to the public. This study aims to identify and analyze the main topics in the video transcripts of President Joko Widodo’s political speeches during the 2014–2024 period using the Latent Dirichlet Allocation (LDA) method. The data consist of 185 press conference speech videos obtained from the Indonesian Cabinet Secretariat’s YouTube channel and converted into text using speech-to-text technology. The dataset is divided into 81 videos from the 2014–2023 period as training data and 104 videos from 2024 as testing data. The analysis process includes text preprocessing, rule-based automatic labeling, LDA model training, and evaluation using coherence score and perplexity. The results show that in the training data, the topics of Infrastructure and Economy are the dominant topics, reflecting the government’s focus on physical development and economic growth. In contrast, in the 2024 testing data, Healthcare emerges as the most dominant topic, followed by the topics of Infrastructure, Economy, Education, and Technology. The Infrastructure topic consistently achieves the highest coherence score of 0.85, indicating strong semantic consistency among its constituent terms. This study contributes to understanding the temporal dynamics of political communication and demonstrates the effectiveness of LDA in analyzing political speech data derived from video transcripts.

Abstract

Analisis emosi dalam teks merupakan salah satu cabang penting dalam Natural Language Processing (NLP), khususnya dalam memahami pesan tersirat pada pidato politik. Pidato politik tidak hanya menyampaikan informasi, tetapi juga emosi yang bertujuan membentuk opini publik. Penelitian ini memanfaatkan model RoBERTa untuk mengklasifikasikan emosi dalam pidato Presiden Joko Widodo selama periode 2014–2024. Data diperoleh dari transkrip video resmi, menghasilkan 2952 paragraf yang telah dilabeli secara otomatis menggunakan model pre-trained `Indonesian-roberta-base-emotion-classifier`. Langkah praproses dilakukan melalui tahapan cleaning, lowercasing, tokenisasi, dan one-hot encoding. Selanjutnya, model RoBERTa dilakukan fine-tuning menggunakan batch size 16, learning rate 1e-5, dan 3 epoch. Evaluasi performa dilakukan dengan confusion matrix dan metrik akurasi, presisi, recall, dan F1-score. Hasil menunjukkan model mampu mengklasifikasikan lima emosi (anger, fear, happy, love, dan sadness) dengan akurasi 90%, presisi 91%, recall 90%, dan F1-score 0,91. Temuan ini menunjukkan bahwa RoBERTa efektif digunakan untuk klasifikasi emosi dalam teks pidato politik berbahasa Indonesia dan memberikan kontribusi terhadap pengembangan NLP dalam konteks komunikasi politik.   Abstract Emotion analysis in texts is a significant branch of Natural Language Processing (NLP), particularly in understanding implicit messages in political speeches. Political speeches not only convey information but also express emotions to shape public opinion. This study utilizes the RoBERTa model to classify emotions in the speeches of President Joko Widodo during the 2014–2024 period. The dataset was obtained from official video transcripts, resulting in 2952 paragraphs labeled automatically using the pre-trained model `Indonesian-roberta-base-emotion-classifier`. The preprocessing stages included text cleaning, lowercasing, tokenization, and one-hot encoding. The RoBERTa model was fine-tuned using a batch size of 16, a learning rate of 1e-5, and 3 epochs. Performance evaluation was conducted using a confusion matrix and metrics such as accuracy, precision, recall, and F1-score. The results show that the model can classify five emotions (anger, fear, happy, love, and sadness) with 90% accuracy, 91% precision, 90% recall, and an F1-score of 0.91. These findings demonstrate that RoBERTa is effective for emotion classification in Indonesian political speech texts and contributes to the development of NLP in political communication contexts.

Abstract

BUMDes is an instrument that drives the macro economy at the village level based on local potential and wisdom. Management of BUMDes in a professional manner can be a solution in order to advance and prosper all elements of village society.BUMDes Mitra Sejahtera is the BUMDes of Kaotan Blimbingsari village which has business activities in the form of buying and selling food and renting agricultural equipment. The management of Mitra Sejahtera BUMDes has been carried out on a traditional conventional basis. The majority of the people in Kaotan Blimbingsarivillage are Muslims with the value of mutual cooperation that thrives in the community.BUMDES business activities must be based on benefits and do not contain elements of persecution (tyranny) for the community.Departing from the spirit of doing changes for the better, the condition of the Kaotan village community and the principles of BUMDes business activities, the authors conclude that the implementation of the Sharia economic system is a solution for BUMDes Mitra Sejahtera. Therefore, the socialization of Islamic economic contracts is an important necessity for the managers of BUMDes Mitra Sejahtera. The socialization material includes Sharia business principles and forms of Sharia contracts.The implementation of this activity is packaged in a workshop. Activities carried out using the method of lectures, discussions and practices at the Kaotan Village-Owned Enterprise. This activity is carried out not once but through several stages in accordance with the material that has been compiled by the presenter
