This study aims to analyze the role, contribution, and convergence of the Sinden (traditional female singer) profession in strengthening the family economy while navigating the challenges of religious identity in Solo, Central Java. This study uses a qualitative approach with an interpretive paradigm and a phenomenological approach. The data collection technique uses in-depth interviews with active Sinden informants with dual roles as housewives and artists. The results of the study indicate that the economic contribution of the head of the family includes the role of an economic safety valve, household financial manager, and teamwork builder in the family. The study also reveals a convergence between religious beliefs and their profession, as Sinden. Despite the ambiguity of this profession in religious communities, primarily due to stage performances that do not strictly adhere to Islamic guidelines, Sinden consistently upholds standards of modesty, religious principles, and their dignity as Muslim women. This study contributes to providing an overview of the dualism of women's roles in the context of Javanese-Islamic culture, which adds insight into the complex interactions between gender, economy, art, and religion in the lives of contemporary traditional societies.

This research aims to classify the level of student satisfaction at Universitas Terbuka (UT) Surakarta using Natural Language Processing (NLP) techniques and machine learning algorithms. The study utilizes textual responses from student satisfaction surveys and processes them through a supervised classification approach. By applying methods such as TF-IDF for feature extraction and classification algorithms like Naïve Bayes, Support Vector Machine (SVM), and Random Forest, the research seeks to identify which algorithm best categorizes sentiment into satisfaction levels. Results indicate that the SVM model outperforms other algorithms in accuracy, precision, and F1-score. This approach demonstrates the practical application of NLP in higher education quality assurance and offers valuable insights for policymakers.

This community service activity was carried out in Mlopoharjo Village, Wuryantoro District, Wonogiri Regency, Central Java, where the majority of the population works as farmers and ranchers. Based on data from Statistics Indonesia, around 60% of productive land is rice fields, while the rest is yards and plantations that have not been optimally utilized. The UT Surakarta Community Service Team sought to improve the welfare of the community through the cultivation of medicinal plants such as ginger, turmeric, and galangal in yards. Herbal plants were chosen because they are easy to cultivate, beneficial to health, chemical-free, inexpensive, and have high economic value. Additionally, these plants are suitable for cultivation during the dry season. To support sustainable cultivation, the team provides jet pumps as a water source for backyards, especially in areas prone to drought. This program is implemented through outreach and training, as well as seed distribution, so that the harvest can be consumed or sold to improve residents' economic conditions.
