Abstract

Laboratory-scale Nannochloropsis sp. cultures typically rely on expensive commercial nutrients for aquaculture feed production. Shrimp head waste contains important nutrients that can be used to produce liquid organic fertilizers. This study aimed to evaluate the effect of using commercial fertilizer combined with liquid organic shrimp head fertilizer (LOF) on the growth of Nannochloropsis sp. on a controlled scale. The experimental design included four treatments (P0:100% commercial fertilizer), P1 (50% commercial + 50% LOF), P2 (75% commercial + 25% LOF), and P3 (100% LOF). Cell growth data were subjected to ANOVA and Duncan's tests. The use of LOF significantly influenced the growth of Nannochloropsis sp. on day 7. Peak growth occurred on day 7. P0 treatment (100% commercial fertilizer) showed the highest growth (15.7 × 104 cells/ml), although it was not statistically different from P1 (50% commercial + 50% LOF) and P2 (75% commercial + 25% LOF). The highest Specific Growth Rate was observed in the P0 treatment (0.22). This suggests that while shrimp head LOF alone may not be sufficient, its combination with commercial fertilizers holds promise for the sustainable cultivation of Nannochloropsis sp.

Abstract

This study aims to analyze the determinants of midwife performance in Kendari City by integrating the influence of Self Efficacy, the mediating role of Work Engagement, and the role of Work Commitment moderation. Using a quantitative approach with an explanatory design, this study involved 210 midwives in the Kendari City area as respondents. Data were collected through a structured questionnaire survey and analyzed using the Structural Equation Modeling method based on Partial Least Squares (SEM-PLS). The results of the study show that Self Efficacy has a fundamental role in improving midwife's performance directly, as well as being a strong predictor in building Work Engagement. Furthermore, Work Engagement has been proven to have a positive and significant effect on the performance of midwives. The crucial finding that became a novelty in this study was the role of Work Commitment as a moderation variable; The test results prove that work commitment acts as a catalyst that strengthens the positive influence of Work Engagement on midwifery performance. This means that the performance of midwifery services will reach an optimal point when midwives have high self-efficacy, feel attached to their work, and are supported by a strong commitment to the organization.
