Kemajuan teknologi informasi mendorong perubahan sistem pendidikan, termasuk kebijakan perkuliahan online sejak pandemi COVID-19. Penelitian ini menganalisis sentimen mahasiswa terhadap kebijakan tersebut menggunakan pendekatan multibahasa dengan algoritma K-Nearest Neighbor (KNN) dan Naïve Bayes. Adapun aspek pembeda penelitian ini adalah penggunaan data dari bahasa Indonesia dan bahasa daerah Sulawesi Barat, yaitu bahasa Mandar, yang menambah kompleksitas tahap preprocessing. Data dikumpulkan melalui kuesioner yang menghasilkan 1.680 opini mahasiswa, dan setelah tahap preprocessing menghasilkan 1.679 data yang siap dianalisis. Hasil klasifikasi menunjukkan algoritma K-Nearest Neighbor terdapat 1002 kategori positif dan 677 kategori negatif. Kemudian pada algoritma Naïve Bayes terdapat 1020 kategori positif dan 659 kategori negatif. Berdasarkan hasil klasifikasi, mayoritas opini bersifat positif, mencerminkan bahwa mahasiswa menerima adanya kebijakan tersebut. Hasil evaluasi melalui confusion matrix serta K-Fold Cross Validation menunjukkan bahwa pendekatan klasifikasi Naïve Bayes mengungguli KNN dengan accuracy 74.87%, precision 74.92%, recall 74.87%, dan f1-score 74.64%. Sementara itu, KNN mencatat accuracy 72.84%, precision 72.80%, recall 72.84%, dan f1-score 72.67%. Hal tersebut mengindikasikan bahwa Naïve Bayes mempunyai kemampuan generalisasi yang lebih unggul pada konteks data teks multibahasa yang kompleks. Penelitian ini menyoroti pentingnya strategi evaluasi dan teknik preprocessing yang sesuai dalam klasifikasi sentimen multibahasa.

The social conflict that occurred in Negeri Masihulan, Central Maluku Regency, in April 2025, resulted in dozens of residents' houses burning down and had serious psychological impacts, especially for children. Children as a vulnerable group experience fear, anxiety, and trauma due to conflict and displacement situations. This community service aims to provide psychosocial assistance through trauma healing as an effort for non-litigation legal protection for child victims of social conflict. This activity was carried out using the approach of playing, drawing, telling stories, and praying together, attended by 30 children aged 5-13 years. The results of the activity showed positive changes in the emotional condition of children, a growing sense of security, and an increased spirit of togetherness after the conflict. Trauma healing has proven to be an effective instrument in psychological recovery as well as a form of implementation of community-based legal protection. It is hoped that this activity will become a model in handling child victims of conflict in areas prone to social conflict in Maluku.

This service activity was carried out by students who carried out KKN at STF UIN Jakarta with a focus on raising and optimizing productive waqf funds for the construction of an Empowerment House in Cidokom Village. Through the Participatory Action Research (PAR) method, this activity involves students, lecturers, local communities and international volunteers in raising funds and implementing economic empowerment programs. As a result, the Empowerment House has become an educational and economic center that supports improving people's skills and independence, while also functioning as an integrated laboratory for students and lecturers. The success of this program shows that productive waqf can be a strategic instrument in building a sustainable and inclusive community economy.

Kampung Depet Indah is one of the villages in the Celala District, Central Aceh District. Kampung Depet Indah is located in an area that is remote in the District of Celala with its vast natural potential with agricultural land and plantations. Based on the results of surveys conducted on several farms and plantations, there are still many farmers who on average use chemical fertilizers as a source of additional or substitute nutrients needed by plants to support growth. One of the work programs being carried out is the manufacture of liquid organic fertilizer (POC) from banana peel waste, where POC itself is a liquid organic fertilizer that can be used by farmers as a provider of nutrients for plants and crops. The implementation of making POC up to the socialization stage to the community consists of several stages which include: (1) Preparation of tools and materials (2) Making POC as a sample (3) Making POC posters (4) Socializing POC to the community (5) Question and answer session.
