Abstract

This research aimed to explore how motivation and work discipline impact the productivity of employees at PT. Bangkit Maju Bersama, analyzing both individual and combined effects. An associative research design was employed, utilizing random sampling to select a group of 50 respondents. The data were examined through various statistical methods, including validity and reliability tests, classical assumption tests, regression analysis, correlation analysis, determination coefficient analysis, and hypothesis testing. The findings revealed that motivation significantly influences employee productivity, accounting for 51.4% of the variability in performance outcomes. Similarly, work discipline was found to have a notable impact, explaining 42.6% of the productivity variance. When considering both factors together, they accounted for 62% of the total effect on employee productivity, highlighting a substantial interactive influence. These results underscore the critical roles that both motivation and work discipline play in enhancing work productivity. The implication of this study suggests that organizations must prioritize fostering a motivating work environment alongside reinforcing disciplined work practices. This dual focus not only boosts employee morale but also enhances compliance with organizational standards, ultimately leading to greater productivity. Hence, effective management strategies should be developed to enhance motivational levels and establish clear disciplinary guidelines, as these elements are essential for achieving optimal performance within the workforce.

Abstract

This study aimed to inventory the dragonfly species inhabiting the Sendang Gile Waterfall area, evaluate their diversity, and develop the findings into a local biodiversity-based biology learning resource for senior high school students. A descriptive exploratory approach was employed using a sweep net sampling method along three observation transects. Species diversity was analyzed using the Shannon–Wiener diversity index (H′), evenness index (E), and dominance index (C). The research findings were subsequently developed into a biology booklet and evaluated through expert validation involving material and media specialists. A total of 364 dragonfly individuals representing 12 species from five families were recorded. Euphaea lara lombokensis was the most abundant species, accounting for 119 individuals. The overall Shannon–Wiener diversity index (H′ = 1.81) indicated a moderate level of species diversity, accompanied by a relatively balanced species distribution and low dominance. The developed booklet obtained an average validation score of 90.09%, indicating that it was highly valid and suitable for educational use. These findings demonstrate that the Sendang Gile Waterfall area supports a moderately diverse dragonfly community and that the developed booklet can serve as an effective local biodiversity-based learning resource for biology education in senior high schools.
