Abstract

Pelayanan kampus yang baik sangat penting untuk menunjang proses belajar mengajar di perguruan tinggi. Salah satu cara untuk meningkatkan pelayanan adalah dengan menggunakan chatbot. Chatbot dapat memberikan pelayanan yang cepat dan efisien kepada mahasiswa, serta membantu dalam mendapatkan informasi yang dibutuhkan. Chatbot dapat memberikan pelayanan yang efektif dan efisien dalam menyediakan informasi dan melakukan transaksi. Penggunaan chatbot juga mengurangi beban kerja petugas administrasi dan memungkinkan mereka untuk fokus pada tugas yang lebih kompleks. Meskipun demikian, perlu perbaikan dalam aspek keamanan data dan privasi. Penelitian ini bertujuan untuk menguji aplikasi chatbot pelayanan administrasi dengan menggunakan metode string matching. Pengujian dilakukan melalui beberapa tahap, termasuk pengujian fungsi, interaksi, kompatibilitas, keamanan, dan performa chatbot. Hasil pengujian menunjukkan bahwa chatbot memiliki tingkat akurasi sebesar 90% dengan metode string matching. Mayoritas mahasiswa merasa puas dengan kecepatan dan akurasi respon chatbot. Selain itu, aplikasi ini juga dianggap mudah digunakan oleh mahasiswa. ABSTRACTCampus services are crucial for supporting the teaching and learning process in higher education institutions. One effective approach to enhance these services is through the implementation of chatbots. Chatbots provide prompt and efficient assistance to students, enabling them to easily access the necessary information. They offer an efficient and effective means of delivering services by providing accurate information and facilitating transactions. Furthermore, the utilization of chatbots alleviates the burden on administrative staff, allowing them to focus on more complex tasks. However, it is important to address and improve data security and privacy aspects. This research aims to evaluate an administrative service chatbot using the string matching method. The evaluation process encompasses assessing the chatbot's functionality, interaction capabilities, compatibility, security measures, and overall performance. The results demonstrate an impressive 90% accuracy rate achieved through the implementation of the string matching method. The majority of students’s express satisfaction with the chatbot's promptness and accuracy in providing responses.

Abstract

Perbedaan bahasa mencerminkan keberagaman budaya dan sejarah suatu negara. Memahami perbedaan ini memperkaya wawasan dan meningkatkan komunikasi global. Dalam rapat internasional, peserta yang tidak memahami bahasa asing sering mengalami kesulitan dalam berpartisipasi aktif, terutama di ruang tertutup, sehingga menghambat pencapaian tujuan diskusi. Penelitian ini mengembangkan sistem Speech to Text berbasis deep learning, menggunakan Mel-Frequency Cepstral Coefficients (MFCC) untuk menganalisis sinyal suara dan Convolutional Neural Network (CNN) untuk meningkatkan akurasi pengenalan serta koreksi ejaan. Raspberry Pi digunakan sebagai penghubung antara headset dan sistem, memungkinkan penerjemahan real-time. Sistem ini juga mengintegrasikan DeepL API sebagai mesin penerjemah dan Text to Speech untuk menghasilkan keluaran suara. Sebagai studi kasus, pengujian dilakukan di Politeknik Negeri Malang kelas internasional, dengan peserta yang terdiri dari mahasiswa dan pengajar yang memiliki latar belakang bahasa yang berbeda. Hasil pengujian menunjukkan metode CNN mencapai rata-rata akurasi 98%, membuktikan efektivitasnya dalam meningkatkan transkripsi dan penerjemahan otomatis. Sistem ini mampu mendukung komunikasi lintas bahasa secara efisien dan real-time, memfasilitasi pemahaman dalam diskusi multibahasa, dan meningkatkan interaksi di lingkungan akademis internasional.   ABSTRACT Language differences reflect the cultural and historical diversity of a country. Understanding these differences enriches knowledge and enhances global communication. In international meetings, participants who do not understand foreign languages often face difficulties in actively participating, especially in closed settings, thus hindering the achievement of discussion goals. This research develops a Speech to Text system based on deep learning, using Mel-Frequency Cepstral Coefficients (MFCC) to analyze sound signals and Convolutional Neural Networks (CNN) to improve accuracy in recognition and spelling correction. A Raspberry Pi is used as a connector between the headset and the system, enabling real-time translation. The system also integrates the DeepL API as the translation engine and Text to Speech for generating audio output. As a case study, testing was conducted at Politeknik Negeri Malang's international class, with participants consisting of students and instructors from diverse language backgrounds. The test results showed that the CNN method achieved an average accuracy of 98%, demonstrating its effectiveness in improving transcription and automatic translation. This system effectively supports real-time, cross-language communication, facilitates understanding in multilingual discussions, and enhances interaction in the international academic environment.

Abstract

High-quality campus services play a crucial role in supporting educational activities in higher education institutions. One approach to enhancing these services is by leveraging chatbot technology. Chatbots can provide swift and efficient responses to students, simplifying access to information and facilitating various transactions. Moreover, chatbots help reduce the workload of administrative staff, allowing them to concentrate on more complex responsibilities. However, data security and privacy remain critical aspects that require further improvement to ensure user trust. This study focuses on evaluating a chatbot application designed to support administrative services in the Electrical Engineering Department of the State Polytechnic of Malang using the string matching method. The evaluation process includes testing the chatbot’s functionality, interaction quality, compatibility, security, and overall performance. Results indicate that the chatbot achieves an accuracy rate of 90% in addressing students’ inquiries. Most users expressed satisfaction with the chatbot’s response speed and precision. These findings suggest that chatbots are an effective solution for improving administrative services, particularly in the context of the Electrical Engineering Department at the State Polytechnic of Malang.
