Abstract

The purpose of this study was to determine the effect of training and communication on employee performance at the South Tangerang Branch of the Air Police Directorate partially and simultaneously. The method used was quantitative. The sampling technique used the Slovin formula and obtained a sample of 87 respondents. Data analysis used validity tests, reliability tests, classical assumption tests, regression analysis, correlation coefficients, determination coefficients and hypothesis tests. The results of this study are that training has a significant effect on employee performance with the regression equation Y = 14.117 + 0.637X1, a correlation coefficient value of 0.602 (strong), a determination coefficient of 36.2% and a hypothesis test obtained t count > t table or (6.948 > 1.988). Communication significantly influences employee performance, as shown in the regression equation Y = 13.188 + 0.645X2, with a correlation coefficient of 0.684 (strong), and a coefficient of determination of 46.8%. The hypothesis test yielded a calculated t-value > t-value (8.642 > 1.988). Training and communication simultaneously significantly influence employee performance, as shown in the regression equation Y = 6.928 + 0.346X1 + 0.477X2. The correlation coefficient was 0.737 (strong), with a coefficient of determination of 54.3%, while the remaining 45.7% was influenced by other variables. The hypothesis test yielded a calculated F-value > F-value (49.932 > 3.110).

Abstract

This study aims to analyze sustainable tourism education in Lerep Tourism Village, Semarang Regency, by examining four key components: the forms of educational tourism offered, and the implementation of sustainable tourism principles. Using a mixed-methods approach, quantitative data were collected through questionnaires to assess tourist attraction potential and the effectiveness of educational programs, while qualitative data were obtained through in-depth interviews, observation, and documentation to evaluate Pokdarwis readiness and sustainability practices. The results show that Pokdarwis demonstrates good readiness in fulfilling its roles as facilitator, educator, representative, and technical operator, although improvements are still needed in technical skills and environmental management. The village possesses strong natural, cultural, and man-made attractions that support the development of educational tourism, including environmental education, cultural learning, and community-based training activities. Sustainable tourism principles have been applied, particularly in environmental conservation, community involvement, and local economic empowerment, yet some aspects require further optimization. The study concludes that Lerep Tourism Village has significant potential to strengthen sustainable tourism through structured educational programs, enhanced community capacity, and integrated management led by Pokdarwis.

Abstract

Geography learning has not utilized the potential of the Karangsambung - Karangbolong Geopark geosite as a learning resource. The purpose of this study is to analyze the implementation of outdoor study and evaluate understanding and critical thinking skills after studying rock material in the Karangsambung - Karangbolong Geopark. The research design was Pre-Experimental Design, and One Shoot Case Study approach. The sample of class X 1 was 34 students and 4 geosite. Data collection used observation, interviews, documentation studies, student worksheets, questionnaires and test. Data analysis used descriptive and scoring. The results of the outdoor study in the Karangsambung - Karangbolong Geopark made it easier for students to identify rocks in the field 58,82% (high) and 41,18% (moderate). Students positive responses that outdoor study made it easier and helped them understand rock material 52,90% (aappropriate) and 47,10% (very appropriate). Outdoor study at the Karangsambung - Karangbolong Geopark supported student understanding with 52,94% (high), 35,29 (moderate) and 11,76 (sufficient). Meanwhile, students critival thinking skills average 36 (high) with 50% hight and 50% (moderate).

Abstract

Perkembangan teknologi informasi menuntut siswa untuk memiliki keterampilan literasi digitalyang kuat sebagai bagian dari kompetensi abad ke-21. Literasi digital tidak hanya berkaitan dengankemampuan berpikir kritis dalam mengolah, mengevaluasi, dan memanfaatkan informasi secara tepat.Pengabdian masyarakat ini dilaksanakan di SMK Pariwisata Citayam, Bogor, dengan tujuan meningkatkankesadaran dan keterampilan siswa dalam literasi digital sebagai sarana penguatan kemampuan berpikirkritis. Kegiatan ini dirancang melalui pendekatan pelatihan interaktif, diskusi kelompok, serta simulasipenggunaan media digital dalam konteks pembelajaran pariwisata. Dengan demikian, program pengabdianmasyarakat ini menegaskan urgensi literasi digital sebagai fondasi pengembangan kemampuan berpikirkritis di lingkungan sekolah kejuruan. Literasi digital tidak hanya menjadi keterampilan teknis, tetapi jugainstrumen strategis dalam membentuk generasi yang adaptif, kritis, dan siap menghadapi dinamika duniakerja pariwisata yang semakin digital. Hasil kegiatan menunjukkan bahwa siswa mampu memahamipentingnya literasi digital dalam menghadapi tantangan informasi yang kompleks, termasuk kemampuanmembedakan informasi valid dan hoaks, serta mengembangkan argumen yang logis dan berbasis data.

Abstract

Lung diseases, including COPD, lung cancer, and asthma, are serious global health issues, causing over seven million deaths annually. Advanced technologies, such as deep learning and the Random Forest algorithm, have been effectively utilized to detect and classify lung diseases from imaging data with high accuracy. This study aims to demonstrate the effectiveness of Random Forest in predicting lung diseases. The dataset used consists of 30,000 records with 11 attributes, collected from Kaggle and processed using Orange software version 3.36.2. The implementation of the Random Forest algorithm was conducted with 10 decision trees and six attributes considered at each split. The model was tested using Cross Validation with 10 folds. The testing results showed an AUC value of 0.993, indicating a very high level of accuracy. A confusion matrix was used to measure the model's performance through various metrics, including accuracy, precision, recall, F1-score, and AUC. This model achieved high accuracy, with ROC AUC values of 0.453 for predicting the presence of lung disease and 0.547 for predicting its absence. These results confirm that the Random Forest algorithm is an effective predictive tool for identifying lung diseases. This study makes a significant contribution to the development of more accurate and efficient diagnostic techniques, assisting medical professionals in identifying lung diseases in patients. With a deeper understanding of how this algorithm operates in the healthcare domain, it is expected to significantly enhance the quality of patient diagnosis and care.
