Mental health issues among university students have become a growing concern, driven by academic pressures, career uncertainties, and complex social transitions. However, a large proportion of students remains reluctant to seek professional psychological support due to social stigma and limited access to institutional counseling services. This study proposes the design and implementation of an Android-based chatbot application that integrates mood tracking and sentiment analysis to continuously monitor the emotional states of university students. The system employs a fine-tuned RoBERTa (Robustly Optimized BERT Pretraining Approach) model trained on the EmoContext conversational dataset (SemEval-2019 Task 3), comprising 30,160 labeled three-turn dialogue instances across four emotion classes: angry, happy, sad, and others. The model was fine-tuned for four epochs using the AdamW optimizer with a learning rate of 2e-5 and a maximum sequence length of 128 tokens. Evaluation on a held-out validation set of 6,032 samples yielded an overall accuracy of 88.28%, a macro-average F1-score of 0.87, and a weighted-average F1-score of 0.88. Per-class F1-scores were 0.89 (angry), 0.83 (happy), 0.91 (others), and 0.86 (sad). The classified emotion is transmitted in real time to the chatbot response logic, which generates empathetic replies and personalized relaxation recommendations based on the detected mood. Primary data collection through questionnaires and interviews with 62 and 19 university students respectively confirmed the need for accessible digital mental health support. The results demonstrate that RoBERTa-based fine-tuning on conversational data provides a reliable foundation for real-time emotion-aware mental health chatbot systems.

Diarrhea remains a leading cause of mortality among toddlers in Indonesia, with a prevalence reaching 4,9%. In addition to pharmacological management through LINTAS DIARE, non-pharmacological therapies such as baby massage are increasingly being implemented as supportive interventions that families can perform to accelerate recovery. This study aims to examine the effectiveness of baby massage as a complementary therapy in reducing the frequency and intensity of diarrhea in toddlers. The method used involved identifying relevant articles from Google Scholar and Semantic Scholar databases using appropriate keywords. Based on the 6 articles obtained, baby massage significantly (p = 0,000) reduces the frequency and intensity of diarrhea through vagus nerve stimulation, which optimizes intestinal peristalsis and nutrient absorption. Beyond improving defecation patterns, this therapy is proven to significantly increase infant weight, accelerate motor development through central nervous system stimulation, and enhance sleep quality and comfort.

Understanding mathematical concepts is a fundamental ability that elementary school students must possess, particularly in multiplication, which serves as a foundation for learning more advanced mathematical topics. Based on the conditions observed in the fourth-grade class at UPT SDN 185 Gresik, there are still students who do not fully understand the concept of multiplication, as the learning process tends to emphasize memorization rather than conceptual understanding. In addition, differences in learning styles and gender are suspected to influence students’ conceptual understanding abilities. Therefore, this study aims to describe the conceptual understanding of fourth-grade students in multiplication, viewed from their learning styles and gender.This study employs a descriptive qualitative research method, with six fourth-grade students of UPT SDN 185 Gresik as the research subjects. Data were collected through learning style questionnaires, concept understanding tests and questionnaires, and interviews. Data analysis was conducted through the stages of data reduction, data presentation, and conclusion drawing, based on indicators of conceptual understanding. Data validity was ensured using triangulation of techniques, sources, and time. The results of the study indicate that auditory learners tend to have better conceptual understanding compared to visual and kinesthetic learners, and female students outperform male students. Based on these findings, teachers need to implement differentiated instruction tailored to students’ learning styles: using diagrams, images, and colored multiplication tables for visual learners; applying discussions, question-and-answer sessions, and repeated verbal explanations for auditory learners; and utilizing concrete teaching aids along with hands-on activities for kinesthetic learners to optimize conceptual understanding.

Libraries play a crucial role in broadening the public's knowledge horizons by improving literacy skills.

This study concludes that product bundling strategies, loyalty programs, reactivation campaigns, and premium services can be applied to increase the effectiveness of coffee shop businesses.

This study aims to analyze the relationship between caffeine consumption and sleep duration on VO₂Max levels among soccer school (SSB) students in Surabaya. VO₂Max is a key indicator of cardiorespiratory fitness and athletic performance. This research employed a quantitative cross-sectional design with an analytical observational approach. A total of 162 SSB students were included as research participants from several soccer schools in Surabaya. Data were collected using the Food Frequency Questionnaire (FFQ) to assess caffeine intake and the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep duration, and were analyzed using the Chi-Square test. The results revealed a significant relationship between caffeine consumption and sleep duration with VO₂Max (p<0.001). Students with higher caffeine consumption (≥3.5) and adequate sleep duration (≥7 hours) tended to have better VO₂Max values compared to those with lower caffeine intake and insufficient sleep. These findings indicate that appropriate caffeine consumption and adequate sleep duration play an important role in improving cardiorespiratory fitness. Therefore, proper education on healthy lifestyle habits is essential to optimize the performance of young athletes.

This study examines the dominance of mother tongue use in junior high school environments and its implications for the use of Indonesian as the language of instruction. The research is grounded in the sociolinguistic reality of multilingual Indonesian society, where students tend to rely on their first language in daily communication. The objective of this study is to analyze the factors influencing the dominance of mother tongue, its impacts on students’ Indonesian language proficiency, and its pedagogical implications. This study employs a qualitative approach using a literature review design, analyzing relevant scholarly sources published in recent years. The findings indicate that the dominance of mother tongue is influenced by linguistic, social, and psychological factors, including family environment, peer interaction, and limited Indonesian vocabulary mastery. The study reveals dual impacts: while mother tongue use facilitates comprehension and increases students’ confidence, it also potentially hinders formal Indonesian language development and leads to language interference. The study concludes that mother tongue should not be viewed solely as a barrier but as a potential pedagogical resource. The implications suggest that educators should adopt contextual bilingual strategies to optimize Indonesian language learning in multilingual classrooms.

Learning fiqh is a very important thing to learn because fiqh regulates all the laws of Allah related to human work where the laws are taken from the Qur'an and Sunnah by means of ijtihad. However, in the field there are still many students who do not understand how to perform tayammum taharah correctly. This happens due to lack of understanding and insufficient habits. Thus, this PKM activity aims to educate students related to taharah so that students not only understand theory, but can apply it in daily life according to Islamic law. The method used is Asset Based Community Development (ABCD) with the stages of discovery, dream, design, define, and destiny. To optimize local potentials such as the competence of ustazah and TPQ facilities, through lectures, demonstrations, discussions, hands-on practice, and evaluation based on interactive quizzes. The results of the tayammum mentoring activities show that TPQ Darul Falah students are very active and interactive during learning. Students who initially did not understand the procedures of tayammum properly and perfunctorially, are now able to do it according to Islamic law. In addition, this training activity provides direct understanding and experience to ustazah and students of TPQ Darul Falah in learning tayamum practice.

This research is motivated by the importance tank cleaning process on tankers to prevent cargo contamination, maintain cargo quality, and ensure crew safety. MT. Marina Prosperity, a chemical/oil tanker, uses the Butterworth system as the primary method for tank cleaning at every cargo change. However, in practice, technical and operational constraints are still found that affect the results of tank cleaning. The research method used is descriptive qualitative with data collection techniques through direct observation on the ship, interviews with the Chief Officer and Boatswain, and documentation studies in the form of log books and SOPs. Data were analyzed by focusing on three aspects, namely work efficiency, work safety, and operational procedures for using Butterworth. The results show that the use of Butterworth can increase time and energy efficiency compared to manual methods, with an average cleaning time of 2–4 hours per tank depending on the type of cargo. From a safety aspect, Butterworth reduces the need for crew to enter the tank, thereby reducing the risk of exposure to chemicals and hazardous atmospheres. However, work effectiveness and safety are greatly influenced by the condition of the equipment, the stability of water pressure, and the crew's discipline in implementing the SOP. On several occasions, steps such as nozzle cleaning, manual mopping, and safety meetings were not consistently performed, resulting in residual load in certain areas. With routine equipment maintenance, close supervision, and ongoing crew training, Butterworth can be optimized to produce more effective, safe, and standards-compliant tank cleaning process.

This qualitative literature review investigates how tax scrutiny influences investor behavior in the cryptocurrency market, with a focus on tax-loss harvesting and wash trading strategies. As governments enhance transparency and enforcement, crypto investors increasingly adapt their behaviors to optimize after-tax outcomes. The review synthesizes recent academic findings that highlight the growing use of legal tax-loss harvesting and the controversial persistence of wash trading, particularly in unregulated exchanges. Evidence suggests that regulatory uncertainty and inconsistent tax treatment across jurisdictions drive strategic investor responses and, in some cases, unintended compliance gaps. This study underscores the need for updated tax frameworks capable of addressing the unique characteristics of digital assets. The analysis contributes to the broader discourse on how taxation shapes market behavior in emerging financial ecosystems

This study examines the effectiveness of rehabilitation programs for drug addicts who repeatedly abuse narcotics at Badan Narkotika Nasional Kota Kupang. The research was motivated by the increasing complexity of drug abuse and the recurrence of abuse (relapse) among former addicts after rehabilitation. This research aims to analyze the implementation of rehabilitation programs and identify the supporting and inhibiting factors affecting rehabilitation effectiveness. The study employed empirical legal research with a socio-legal approach. Primary data were obtained through interviews and field observations, while secondary data were collected through the study of legislation, books, journals, and related legal documents. Data were analyzed qualitatively using the theories of legal implementation, legal effectiveness, and legal utility. The findings indicate that rehabilitation programs were implemented through assessment, medical rehabilitation, social rehabilitation, and post-rehabilitation stages. During the 2021–2025 period, 25 rehabilitation clients were recorded, with two relapse cases identified, consisting of one moderate relapse case in 2021 and one mild relapse case in 2024. The effectiveness level of the rehabilitation program ranged between 70% and 80%. Supporting factors included legal frameworks, interinstitutional cooperation, family support, and community-based rehabilitation services. Meanwhile, inhibiting factors involved limited professional human resources, inadequate facilities, budget constraints, social stigma, and environmental influences that triggered relapse. The study concludes that rehabilitation for repeat drug abusers in Kupang has been relatively effective; however, institutional strengthening, improvement of rehabilitation facilities, and community participation remain necessary to optimize rehabilitation outcomes.

This study aims to evaluate the determinants of organizational sustainability within the Doctor Peduli Foundation (doctorSHARE), specifically regarding its Floating Hospital program. Specifically, it examines the influence of stakeholder support and operational efficiency on organizational sustainability, while analyzing the role of organizational innovation as a mediating variable in ensuring the continuity of medical services in remote areas. Employing a quantitative approach with a survey method, data were collected from 81 respondents comprising staff and volunteers directly involved in the Floating Hospital's operations. Structural Equation Modeling (SEM) was utilized to analyze the data and test the proposed hypotheses.The results reveal that stakeholder support does not have a significant direct impact on either organizational sustainability or innovation performance. Conversely, operational efficiency emerged as a dominant factor with a significant positive influence. Furthermore, organizational innovation was found to play a crucial role as a mediator, strengthening the impact of operational efficiency on organizational sustainability.This study concludes that the sustainability of non-profit organizations such as doctorSHARE is determined more by management's ability to optimize internal resources efficiently and innovatively than by reliance on external support. Consequently, strengthening internal operational systems should be a primary strategic priority to ensure long-term organizational existence.

This study aims to analyze the role of the Department of Tourism and Culture in preserving traditional houses in Wanokaka District, West Sumba Regency. The research employed a descriptive qualitative method with a field study approach through observation, interviews, and documentation. The informants consisted of officials from the Department of Tourism and Culture, district and village governments, traditional leaders, traditional house owners, and young generations. The findings indicate that the Department of Tourism and Culture has carried out its role as regulator, dynamizer, and facilitator in the preservation of traditional houses.
