Abstract

This study investigated the effects of marinating chicken meat with varying concentrations of lime juice (Citrus aurantifolia) on its physical properties, specifically pH, tenderness, water-holding capacity (WHC), and cooking loss. The experimental treatments comprised five lime juice concentrations: P0 (control, 0 mL), P1 (10 mL), P2 (20 mL), P3 (30 mL), and P4 (40 mL). The results revealed significant differences in pH values among treatments: P0 (5.67), P1 (5.25), P2 (5.01), P3 (4.91), and P4 (4.78). Tenderness, expressed as penetration force (mm/g), varied across treatments with the following means: P0 (91.13 mm/g), P1 (80.63 mm/g), P2 (81.00 mm/g), P3 (88.50 mm/g), and P4 (69.00 mm/g). WHC values were recorded as follows: P0 (44.41%), P1 (43.40%), P2 (42.52%), P3 (45.00%), and P4 (43.80%). Cooking loss increased with higher lime juice concentrations: P0 (27.00%), P1 (32.50%), P2 (33.00%), P3 (32.50%), and P4 (34.50%). The findings suggest that lime juice concentration significantly affects both pH and tenderness, with the most favorable results observed at the 20 mL concentration, which yielded a pH of 5.01 and tenderness of 81.00 mm/g. In contrast, no significant effects were observed on WHC and cooking loss across treatments. In conclusion, marination with 20 mL of lime juice enhances the physical quality of chicken meat by improving pH and tenderness, without substantially affecting water retention or cooking loss.

Abstract

This study aims to evaluate the level of learning nahwu, measure the ability of students in nahwu, and assess the effectiveness of using the Al Ikhtishor method in nahwu learning at Durrotu Ahlissunnah Waljama'ah Islamic Boarding School. This research uses quantitative methods with experimental design, involving control classes and experimental classes. Data collection techniques include tests, interviews, and documentation. Data analysis was carried out through normality tests, homogeneity tests, and T tests (Paired Sample T Test and Independent Sample T-Test ). The results showed that the level of use of the Al Ikhtishor method was adequate, the ability of students in learning nahwu science was very good, and the use of the Al Ikhtishor method proved effective in increasing understanding and mastery of nahwu among students. The Al Ikhtishor method significantly increases the understanding and mastery of nahwu among students. The conclusion of this study is that the Al Ikhtishor method is effective in improving the quality of nahwu learning, and this method is recommended for use in teaching nahwu science in Islamic boarding schools.
