Abstract

This study aims to examine the Strategic Human Resource Management (SHRM), Internal Environtmental Orientation (IEO), and Organizational Citizenship Behavior Environment (OCBE) in a manufacturing company in Jakarta and its surrounding areas. It is specifically aimed to identify whether there is an influence of SHRM and IEO to OCBE and to investigate  whether the IEO  moderately influences SHRM to OCBE. The respondents of this study are employees of manufacturing company from different levels and positions  from several industries. The selection of respondents is done by convenience sampling and it successfully collects 150 respondents. The results of descriptive analysis show that SHRM, IEO, and OCBE on the company they work is acceptable but it still needs improvement. In addition it is found that there is a significant positive influence of SHRM and IEO variables to OCBE. However, IEO variable does not moderately influence SHRM to OCBE.

Abstract

General Background Collaboration skills are essential competencies in contemporary education, particularly within problem-based and interactive learning environments. Specific Background Problem-Based Learning integrated with deep learning and differentiated approaches has been proposed to support meaningful engagement and teamwork among vocational students. Knowledge Gap However, empirical evidence on how differentiated PBL combined with deep learning systematically strengthens collaboration skills in formal vocational education remains limited. Aims This study aims to examine the application of differentiated PBL with deep learning to strengthen students’ collaboration skills through iterative classroom action cycles. Results The findings show a progressive increase in collaboration skills from 30.22% in the first cycle to 87.21% in the third cycle, accompanied by improved teaching quality from 46% to 87%, indicating a strong positive relationship between instructional quality and collaborative performance. Novelty The study introduces the integration of differentiation across material, process, and product within PBL and combines qualitative and quantitative observations in a vocational classroom context. Implications These results highlight the importance of adaptive instructional design, learning style mapping, and structured group interaction to foster inclusive, collaborative learning aligned with 21st-century competencies. Highlights• Progressive cycles demonstrate substantial growth in cooperative performance indicators• Adaptive grouping and varied learning products support inclusive participation dynamics• Instructional quality aligns consistently with improved teamwork engagement KeywordsCollaboration Skills; Problem Based Learning; Differentiated Learning; Deep Learning; Vocational Education

Abstract

Caulerpa racemosa merupakan salah satu makroalga yang memiliki kandungan senyawa bioaktif dan berpotensi sebagai sumber antioksidan alami. Kandungan metabolit sekunder pada C. racemosa dapat dipengaruhi oleh berbagai faktor, salah satunya umur panen. Penelitian ini bertujuan untuk menganalisis kandungan fitokimia dan aktivitas antioksidan ekstrak etanol 70% C. racemosa pada berbagai umur panen. Penelitian dilakukan menggunakan metode eksperimental dengan perlakuan umur panen 20, 25, 30, 35, 40, dan 45 hari. Skrining fitokimia dilakukan secara kualitatif terhadap senyawa flavonoid, alkaloid, tanin/fenol, terpenoid, dan saponin. Aktivitas antioksidan dianalisis menggunakan metode DPPH dan dinyatakan sebagai nilai IC₅₀. Hasil penelitian menunjukkan bahwa ekstrak etanol 70% C. racemosa pada seluruh umur panen positif mengandung alkaloid, triterpenoid, dan saponin, namun negatif terhadap flavonoid, tanin/fenol, dan steroid. Aktivitas antioksidan meningkat seiring bertambahnya umur panen yang ditunjukkan oleh penurunan nilai IC₅₀. Nilai IC₅₀ tertinggi diperoleh pada umur panen 20 hari sebesar 2394,07 μg/mL dan terendah pada umur panen 45 hari sebesar 126,01 μg/mL. Aktivitas antioksidan pada umur panen 45 hari tergolong kategori sedang, sedangkan umur panen lainnya termasuk kategori sangat lemah. Hasil penelitian menunjukkan bahwa umur panen berpengaruh terhadap aktivitas antioksidan C. racemosa dan umur panen 45 hari merupakan waktu panen terbaik untuk memperoleh aktivitas antioksidan yang lebih tinggi. Caulerpa racemosa is a macroalga containing various bioactive compounds and has potential as a natural antioxidant source. The accumulation of secondary metabolites in C. racemosa can be influenced by several factors, including harvest age. This study aimed to evaluate the phytochemical composition and antioxidant activity of 70% ethanol extracts of C. racemosa harvested at different ages. An experimental method was applied using six harvest ages: 20, 25, 30, 35, 40, and 45 days. Phytochemical screening was conducted qualitatively to detect flavonoids, alkaloids, tannins/phenolics, terpenoids, and saponins. Antioxidant activity was determined using the DPPH method and expressed as IC₅₀ values. The results showed that all extracts positively contained alkaloids, triterpenoids, and saponins, while flavonoids, tannins/phenolics, and steroids were not detected. Antioxidant activity increased with harvest age, as indicated by decreasing IC₅₀ values. The highest IC₅₀ value was observed at 20 days of harvest (2394.07 μg/mL), whereas the lowest value was obtained at 45 days of harvest (126.01 μg/mL). The antioxidant activity of the 45-day harvest extract was classified as moderate, while the other harvest ages were categorized as very weak. These findings indicate that harvest age influences the antioxidant activity of C. racemosa, with 45 days being the optimum harvest age for obtaining higher antioxidant potential.
