Development of LKPD Based on Vee Diagram on Diffusion and Osmosis Material in Improving Students\u27 Critical Thinking Skills and Science Process Skills
No full textBackground: The low levels of students\u27 critical thinking skills and science process skills in diffusion and osmosis material remain a problem in biology learning. This study aims to develop a student worksheet based on the vee diagram to improve students’ critical thinking and science process skills. Methods: The research employed a Research and Development (R&D) approach using the ADDIE model. The subjects were 11th-grade science students at MA Nurul Huda Munjul, consisting of 25 students in the experimental class and 25 in the control class. Instruments included multiple-choice tests, observation sheets, and questionnaires. Data were analyzed using N-gain and t-tests. Results: The developed student worksheet was valid (97.02%) and effectively implemented (90%). Students\u27 critical thinking skills increased with an N-Gain of 0.41 (moderate), compared to 0.05 (low) in the control class. Science process skills also improved to 81.75% (high), outperforming the control class (53.63%). The correlation between critical thinking and science process skills was not significant (r = 0.298 < r table = 0.396; sig. = 0.149). Students’ responses to the student worksheet were in the very good category (85.33%). Conclusion: Thus, the development of vee diagram-based student worksheets on diffusion and osmosis material can enchance student’s critical thinking and science process skills
Implementasi Konfigurasi Jaringan Dalam Supply Chain Management Pada Mitra Usaha Es Teh Nusantara yang Berada di Kota Metro
Get PDFThis study aims to analyze the configuration of supply chain management (SCM) in Es Teh Nusantara in Metro City, focusing on operational efficiency and its impact on customer satisfaction. Es Teh Nusantara, as a ready-to-eat beverage company, faces challenges in managing an effective supply chain to reduce costs, accelerate distribution, and maintain product quality. Through a qualitative descriptive approach, data was collected through field observations, interviews with management and business partners, and analysis of related documents. The results of the study show that the network structure of Es Teh Nusantara involves raw material suppliers, factories, storage warehouses, distributors, and business partners. The selection of strategic locations for factories and warehouses has succeeded in reducing transportation costs and raw material procurement time. An efficient distribution system allows for fast and timely delivery of products. Operational efficiency is achieved through the management of cost, time, and maintained product quality, which in turn improves customer satisfaction. However, the study also found challenges related to fluctuations in market demand and suboptimal distribution coordination at a time when demand is increasing rapidly. This research provides several important benefits and contributions to Es Teh Nusantara and the ready-to-eat beverage industry, as well as enriching the literature in the field of supply chain management
Kepemimpinan Transformasional, Motivasi Kerja dan Keterlibatan Kerja Dalam Meningkatkan Kinerja Karyawan Hotel Radjendra Resort and Resto Caringin Bogor
Get PDFThis study aims to see how transformational leadership, work motivation, and work involvement contribute significantly to improving employee performance. The object of the study was employees at the Radjendra Resort and Resto Hotel Caringin Bogor, with a quantitative approach and associative research design. The sample consisted of 52 respondents determined through random sampling techniques using the Slovin formula from a total population of 102 employees. After the data was collected through a Likert-scale questionnaire, multiple linear regression was implemented to analyze it. The findings prove that the three independent variables studied provide a significant contribution to improving employee performance, both separately and simultaneously. This confirms that visionary leadership, strong work motivation, and employee emotional and cognitive involvement collectively create a productive work environment. The uniqueness of this study lies in the simultaneous testing of the three variables in the context of the local hospitality industry, which is still rarely studied. Hopefully, these findings will help make strategic policies for HR management in the hospitality sector

Analisis Perancangan Produk Baru dalam Pespektif Supply Chain Management
Get PDFThis study aims to analyze how the integration between new product planning and supply chain management (SCM) can increase the competitiveness and operational effectiveness of MSMEs in Sukabumi City. Using a descriptive qualitative approach, data was collected through observation, in-depth interviews, and documentation of four types of MSME products, namely Seblak, Wet Spring Rolls, Mochi, and Cireng. The results show that the success of new product launches is greatly influenced by the factors of raw material availability, production time efficiency, distribution strategy, and market response. Mismatches between product design and raw material supply, as well as distribution constraints, are major barriers in the supply chain. Meanwhile, good communication between stakeholders, collaboration in product development, and adaptation to consumer preferences, have been proven to strengthen the competitiveness of products in the market. This research recommends that MSMEs strengthen partnerships with local suppliers, develop production operational standards, innovate in products and packaging, and utilize digital technologies for promotion and distribution. With an integrated SCM approach, MSMEs can accelerate the production cycle, reduce costs, maintain quality, and increase the chances of success of new products in competitive markets

Get PDFNarcotics abuse in Indonesia is increasingly worrying. To optimize the prevention and eradication of this problem, the National Narcotics Agency (BNN) was established through Law Number 35 of 2009. BNN is tasked with preventing and eradicating the abuse and illicit circulation of narcotics effectively. This study aims to analyze the implementation of countermeasures for narcotics abuse by the National Narcotics Agency in Sukabumi City, as well as identify supporting and inhibiting factors in these efforts. The methodology employed draws on criminal policy theory and legal system theory. The results of the study show that BNN has an important role in preventing and eradicating narcotics trafficking. However, challenges still exist, such as a lack of resources and community support. The suggestion for BNN is to increase collaboration with local communities and related agencies, as well as strengthen education programs to increase public awareness about the dangers of narcotics. With these measures, it is hoped that narcotics abuse in the city of Sukabumi can be minimized and similar problems will not occur in the future.

Practicality Test of Quizizz Media in Designing Instructional Problem-Based Learning on Membrane Transport Material
Get PDFBackground: Based on field findings and previous studies, the utilization of digital learning media such as quizizz in instructional design remains suboptimal, particularly within innovative learning models like Problem-Based Learning (PBL). Quizizz has primarily been used as an assessment tool rather than being integrated as an essential component of the instructional process. This study aims to examine the practicality of using quizizz within a PBL-based instructional design for the topic of membrane transport in high school biology. Methods: The research employed a Research and Development (R&D) method using the 4-D model, limited to the develop stage, which focuses on evaluating product practicality. A limited-scale trial was conducted involving 34 grade XI students and one teacher at SMA Negeri 2 Mranggen. A practicality perception questionnaire was used as the research instrument. Results: Quizizz integrated into PBL instructional design was perceived as practical by students, with an average score of 77.72%, and by the teacher, with an average score of 72.50%. Conclusion: These findings indicate that quizizz is a practical tool for use in PBL-based instructional design, particularly for teaching membrane transport in high school biology classes
