Abstract

The continuity of operations in palm oil companies heavily relies on the quality of their human resources. This study aims to assess the relationship and impact of work experience duration on employee performance in the fertilization division. A quantitative approach was employed, using simple linear regression analysis and t-tests. The sample was selected using purposive sampling (saturation sampling), with respondents consisting of employees in the fertilization division. Data were collected through 26 questionnaires and supported by secondary information. The results indicate a positive correlation between work experience and employee performance, although the influence is not statistically significant. The low level of work experience—particularly among employees who have worked for less than a year—is the main factor behind the insignificant impact. This study also highlights the need for companies to provide training and skill development programs to enhance work experience through internal training, as well as to consider other factors such as motivation, a supportive work environment, and effective leadership.

Abstract

This study examines the characteristics of water absorption and load-bearing resistance of coconut coir–based cocopot with different thicknesses as an environmentally friendly planting medium. Cocopots were produced from a mixture of cocofiber, cocopeat, and latex adhesive with three thickness variations: 1.0 cm, 1.5 cm, and 2.0 cm. Water absorption was evaluated using a 5-minute immersion test, while load-bearing resistance was assessed by repeatedly dropping soil-filled cocopots from a height of 3 meters under a total load of 1,096 g. The results show a consistent trend indicating that increased thickness is associated with higher water absorption capacity and improved mechanical durability. Cocopots with a thickness of 2.0 cm exhibited the highest water absorption (90–91%) and the lowest damage level, with a Load-Bearing Resistance Index of 0.55–0.58%. In contrast, cocopots with a thickness of 1.0 cm showed the lowest performance. These findings suggest that thicker cocopots provide better functional characteristics for agricultural applications.
