Abstract

 This research aimed to determine the effect of applying biochar and chitosan-based pesticides on the growth and production of broccoli plants. This research used a factorial randomized block design. The first factor, namely biochar, consists of 4 (four) levels; B0: control, B1: 160 g/polybag, B2: 320 g/polybag, and B3: 480 g/polybag. The second factor, namely chitosan, consists of 3 (three) levels; C0: control, C1: 1.5 ml/l water, and C2: 3 ml/l water. Data analysis used analysis of variance (ANOVA) and further testing using BNT at the 5% level. The results showed that there was no interaction between giving biochar and chitosan on broccoli growth and yield parameters, but separately giving biochar had a significant effect on plant height, number of leaves, leaf area, flower diameter, flower weight, and production yield, chitosan treatment had a significant effect on plant height, number of leaves, leaf area, flowering age, flower diameter, flower weight, wet and dry weight of stover, and production yield. The best biochar treatment was at a dose of 480 g/polybag (B3) with a production yield of 12.69 t/ha compared to the control 11.49 t/ha and the best chitosan treatment was at a dose of 3 ml/l water (C2) with a production yield of 12 .82 t/ha compared to the control, namely 11.09 t/ha. The application of 160 g biochar/polybag + 3 ml chitosan/l showed that it was able to suppress the development of black rot disease with a disease incidence percentage of 0-8% compared to the control of 8-50% and a wound diameter on flowers of 0.00 cm compared to controls of 1.87 cm.

Abstract

This study aims to analyze the impact of reward and punishment policies on employee work discipline at the State Civil Service Agency (BKN) Medan. This research uses a quantitative approach with a descriptive correlational survey method. The research population consists of all employees at BKN Medan, with a sample of 150 employees selected through purposive sampling. Data were collected using a Likert-scale questionnaire and analyzed using multiple regression analysis. Validity and reliability tests were conducted to ensure that the instruments used were valid and reliable. The results show that reward policies have a significant positive effect on employee work discipline (β = 0.45, p < 0.01), meaning that the better the reward policies implemented, the higher the level of employee work discipline. Punishment policies also have a significant positive effect on employee work discipline (β = 0.35, p < 0.01), indicating that the implementation of firm and fair punishments can improve work discipline. The interaction between reward and punishment policies is not significant (β = 0.10, p > 0.05), suggesting that the combined effect of these policies is not significantly different from the effect of each policy individually. These findings support the motivation and reinforcement theory, which states that positive rewards and negative consequences can influence individual behavior. The practical implications of this research are the importance of designing fair and relevant reward policies and consistently applying punishments to enhance employee work discipline. This study also recommends further research with a qualitative approach and broader scope to deepen the understanding of factors affecting work discipline.
