The library is a gate of science and a heart of civilization. Indonesia already has a Perpustakaan Nasional consisted of 27 floors and is equipped with facilities that are adequate for user needs. Apart from that, we need to see opinions from the community as users. Public opinion about the library is critical for library managers to evaluate services and facilities from the library. One way to find out the views of the community is by using social media twitter. Twitter social media is often used in channelling opinions or expressing opinions about specific topics; besides social media, twitter is commonly used for digital campaign movements. Submission of views and even digital campaigns on Twitter social media greatly influence the opinions and even behaviour of society in various ways. This study analyzes tweets about national libraries by classifying, positive opinions, negative opinions and neutral opinions. In this study, twitter data will go through the preprocessing, weighting, and classification stages. TF-IDF and TF binary are used in weighting in this study. The classification used in this study is Naive Bayes and KNN. Accuracy, precision, and recall values were also used in this study to evaluate classification performance. The highest classification performance using KNN classification with TF-IDF weighting resulted in the value of accuracy, precision, and recall of 83.33%, 79.2%, and 83.3% respectively.

This research article discusses the evaluation of the e-thesis information system in the Library and Information Science program at UIN Maulana Malik Ibrahim Malang. The background of this research is that the system is relatively new and is supported by several preliminary surveys conducted among users, most of whom are unfamiliar with the use of this e-thesis application system. The research population was taken from all students of the Library and Information Science Department in the 2018 and 2019 academic years, with a research sample of 50 students. The honeycomb method was used as the analysis tool for the evaluation, which emphasizes how UX can go beyond just usability aspects for users. The assessment aspects in the honeycomb method include useful, usable, desirable, findable, accessible, credible, and valuable. The research results showed that the overall average value of the e-thesis information system was 4.10, indicating that the e-thesis system is considered good in terms of its use. The highest score of 4.23 was found in the useful aspect, indicating that students agreed that the e-thesis information system could solve user problems and meet their needs. The lowest score of 3.93 was found in the accessible aspect, which needs improvement for future development of the information system. Indicators that need attention for improvement include less appealing design and the need to enhance capabilities. Suggested improvements include visual design, an advance search button, display of two thesis advisors, UI refresh, minimizing errors, and detailed schedule display on the homepage. Improving the existing features according to the research conducted can have a wide impact on the use of the information system and can be used continuously without errors.

The outreach activity focuses on improving energy efficiency at Sirothol Mustaqim Mosque in Pasuruan Regency. The primary issue addressed is how to meet the lighting needs of the mosque while minimizing the use of PLN electricity and optimizing the use of lamps and electricity based on the number of congregants. The main objective is to implement renewable energy through solar panels to replace conventional electricity, analyze the efficiency of electricity usage based on lighting requirements, and enhance electricity efficiency based on time and lamp location. Expected outcomes include increased electricity usage efficiency, reduced operational costs for mosque management, and advanced scientific and technological knowledge in the general community. The participatory action research (PAR) method emphasizes active participation and collaboration between academics and the community. The project commences with a field survey to identify energy needs and the potential for solar energy sources on-site. Subsequently, project planning and design are carried out, followed by project implementation with training for mosque administrators. The results of the project's implementation include energy usage efficiency, the integration of renewable energy in a religious context, and contributions to understanding environmental responsibilities. The success of the implementation measure calculations for the usage time of 40-watt lamps using solar energy are provided, along with a comparison of PLN electricity costs and solar energy usage costs. The analyses demonstrate favorable energy efficiency using solar power.

Klasifikasi nada bacaan Al-Qur’an sangat penting untuk mendukung pembelajaran tajwid, tartil, serta tilawah yang sesuai dengan aturan. Tantangan utama dalam klasifikasi ini terletak pada keberagaman gaya bacaan qari dan kemiripan akustik antar maqam. Penelitian ini bertujuan untuk mengembangkan model klasifikasi otomatis irama bacaan Al-Qur’an menggunakan pendekatan berbasis CNN dengan 8 kelas maqam bacaan. Model CNN dalam penelitian ini memiliki tiga jalur konvolusi dengan ukuran kernel berbeda. Variasi bentuk masukan berupa data audio yang diubah ke dalam representasi spektrogram dan mel-frequency cepstral coefficients (MFCC). Evaluasi kinerja model pada dataset bacaan Al-Qur’an yang terdiri dari 8 kelas tilawah yaitu Ajam, Bayat, Hijaz, Kurd, Nahawand, Rast, Saba, dan Seka. Hasil pelatihan menunjukkan bahwa metode yang diusulkan mencapai akurasi 92,6%, sedangkan pada proses pengujian didapatkan akurasi sebesar 82,04%. Hasil confusion matric didapatkan nilai akurasi yang diperoleh dalam proses validasi mencapai 80,88%. Nilai presisi, recall dan F1-score masing-masing adalah 0,82, 0,80, dan 0,81. Dengan hasil ini, pendekatan CNN yang diusulkan terbukti efektif untuk mendukung otomatisasi dan peningkatan akurasi dalam klasifikasi nada bacaan Al-Qur’an.
