This research aims to identify the reproduction and development of Bryophyta, especially the moss Octoblepharum albidum. Moss is a group of lower plants that play an important role in ecosystems, especially in humid areas such as tropical rainforests. The method used in this research includes observing the morphology and reproduction of moss using a stereo microscope to observe sporangium and spores. The results showed that Octoblepharum albidum has a lance-shaped leaf morphology, pale green in color, and has a thick texture. There are four brown sporangium, each containing more than 200 spores. This research reveals the importance of Bryophyta in maintaining ecosystem balance and as environmental indicators, as well as providing insight into the factors that influence the growth and development of moss in different habitats.

This research aims to determine the effectiveness of contextual learning approaches in subjects. Social Sciences (IPS) in Elementary Schools/Madrasah Ibtidaiyah based on literature review. The contextual learning approach is considered relevant because it allows students to connect lesson material with everyday life experiences, thereby improving students' understanding and critical thinking skills. The method used in this research is a literature study, where researchers collect and analyze various literature sources related to contextual learning and its application in social studies learning. These sources include books, scientific journals, and previous research that supports contextual learning theory and practice. The results of the literature review show that a contextual learning approach can increase student engagement, understanding of the material, as well as critical and analytical thinking skills. The contextual learning approach, based on evidence from the reviewed literature, is effective in improving learning outcomes and student involvement in social studies learning in SD/MI. Thus, this approach can be one of the recommended learning strategies to improve the quality of education in elementary schools.

Purpose: The presence of a two-month lag in Hotel Room Occupancy Rate (TPK) data necessitates an alternative method to accommodate adjustments in the economic circumstances of the tourism industry. In this context, TPK is connected to the influx of tourists, making the data a valuable resource for assessing the tourism potential of a particular area. The information can be used to make informed decisions when considering investments in the local tourism industry. Therefore, this research aimed to formulate predictions for future trends using now-forecasting. The variables of Google Trends Index (IGT) and online traveler reviews considered were obtained from big data.
Methods: This research used machine learning methods with Random Forest, LSTM, and CNN-BiLSTM-Attention models in determining the best model. Meanwhile, the datasets were acquired from diverse secondary data sources. Hotel Occupancy Rooms Rate was derived from BPS-Statistics Indonesia, while additional data were collected through web scraping from online travel agency websites such as Tripadvisor.com, IGT with keywords “IKN”, “hotel”, and “banjir”. For the sentiment variable from online reviews, lag effects of one, two, and three months were analyzed to determine the correlation with TPK. The highest correlation was selected for inclusion in the prediction model across all machine learning methods.
Result: The results showed that the use of IGT and online traveler reviews increased the precision of forecasting models. The best model of hotel TPK nowcasting was Random Forest Regression with the lowest MAPE value and accuracy of 5.37% and 94.63%, respectively.
Novelty: The proposed method showed great potential in improving the prediction of hotel TPK by leveraging new technology and extensive data sources. The correlation with TPK decreases with an increasing time lag of sentiment. Therefore, the sentiment of reviews in the current month has the highest correlation with TPK, compared to the previous one, two, or three months.

Additionally, their social interactions with peers and family may also be disrupted, ultimately affecting their social and emotional development. Student service to the community regarding the impact of gadget use on early childhood learning interest and the environment. It is carried out in one stage, namely the stage of providing material which aims to provide an understanding of how to use gadgets wisely so that they can still learn effectively while maintaining a balance with other activities that support their growth and development.

In initial observations at SMP Negeri 20 Surakarta, various emotional and behavioral problems were found among students, including self-injurious behavior due to emotional stress, such as friendship conflicts and social pressure. This phenomenon highlights the importance of psychosocial interventions to increase awareness of mental health among adolescents. Adolescence, as a critical period of biological, psychological and social development, is vulnerable to internal and external conflicts that can affect mental well-being. Data shows that the prevalence of emotional mental disorders in adolescents is increasing, with risk factors including academic pressure, poor interpersonal relationships, and lack of mental health awareness and support. To overcome this, community service activities in the form of mental health psychoeducation were carried out at SMP Negeri 20 Surakarta. This activity includes training in managing emotions, strengthening interpersonal relationships, and increasing student awareness about the importance of mental health. Results show increased student understanding and awareness, as well as positive impacts on psychological well-being, social skills, and academic achievement. It is hoped that this program will be the first step in supporting adolescent mental health and reducing the risk of psychological disorders in the future.

This aims to analyze and examine laboratory quality management in enhancing student competencies. The research method used is qualitative, specifically a case study approach.
