Abstract

Students' engagement in school is a condition where the students can engage in learning activity well, it seems by the students' ability and willingness to engage in the school activity. This research aims to examine the role of academic self-concept as the moderate variable on the relationship between teacher's support and students' engagement in school. This research uses qualitative through the correlational method. Students' engagement is measured by the student's engagement at school questionnaires (SESQ). While the teacher's support is measured by the perceived teacher academic support scale (PTASS). Academic self-concept is a moderate variable that is measured by using the academic self-concept scale (ASC) by measure on two aspects namely students' confidence and students' effort in the academic aspect. Testing hypotheses have one by using moderated regression analysis (MRA). The results show that the relationship between the teacher's support and students' engagement in school is increasingly strengthened by the presence of academic self-concept as a moderated variable. Teacher's supports such as emotional supports in the learning process can enhance academic self-concept positively. The positive self-concept among the students encourage to develop student's self-regulation and achievement academic and automatically increase student's engagement in the learning process.

Abstract

This research used descriptive analysis, cost and income analysis, business efficiency (RCR) analysis, and added value analysis with Hayami method. The result showed that pineapple chips and jackfruit chips agroindustrial business already profitable. An average of 12 businessman ear net income of pineapple chips and jackfruit chips each of Rp. 8.350.062,26 per month and Rp. 1.243.240,79 per month. The processing efficiency of pineapple and jackfruit into pineapple chips and jackfruit chips each of 1,37 dan 1,85. The added value for pineapple processing into pineapple chips is Rp. 2.389,30 with ratio of added value to production equal to 42,79% and added value for jackfruit processing into jackfruit chips is Rp. 15.575,51 with ratio of added value to production equal to 71,61%.

Abstract

Caulerpa racemosa seaweed is a type of seaweed that can be used as an antidiabetic. Previous studies have shown that Caulerpa. sp. was able to reduce blood glucose levels and showed the regeneration of pancreatic ? cells in diabetic rats. The purpose of this study was to determine the effect of C. racemosa seaweed diet on liver and kidney malondialdehyde levels in diabetic rats. The research stages began with chemical analysis of C. rasemosa seaweed flour and continued with bioassay testing. The analysis included proximate analysis, fiber, total phenol and antioxidant activity of C. rasemosa seaweed, analysis of blood sugar in serum and malondialdehyde (MDA) in the liver and kidneys. Results showed that C. rasemosa seaweed flour contained 11.37% water, 23.24% of ash content, 12.84% of protein, 2.02% of fat, 50.45% of carbohydrate by different, 6.35% of crude fiber, total phenol 2785 mg GAE / g, and 15.68% of antioxidant activity. Diet of C. rasemosa seaweed flour for 30 days was able to reduce blood glucose levels by 53.12% in the diabetic rat group. Liver MDA levels in the group of diabetic rats fed a diet C. rasemosa decreased 17.79% compared to the control group. Renal MDA levels in the diabetic rat group fed a diet of C. rasemosa seaweed were still higher than the control group but 15.53% lower than the diabetic group fed standard diet.

Abstract

The objective of this research was to determine the effect of tenggulun leaf tea powder in improving lipid profile in rats fed with high fat diet. We developed a tenggulun leaf tea powder and did a biochemical analysis. The in vivo study was conducted using 18 male Wistar rats grouped into three different diets, Control-Standard Feed (CSF) group, Hypercholesterol-Standard Feed (HSF) group and Hypercholesterolemia-Tenggulun Feed (HTF) group. The treatment was given for 30 days in all groups. Biochemical analysis showed that tenggulun leaf tea powder contains various cholesterol lowering substance such as dietary fibre (42.73%), phenolic content (9.42 mg GAE/g), tannins (10.80 mg TAE/g), flavonoids content (1.81 mg QE/g), and it also showed antioxidant activity (IC50 value of 67.20 ppm). In vivo analysis after treatment showed that there was no significant difference in total cholesterol levels between the HSF and HTF groups. However, in the HTF group there was a decrease in total cholesterol levels from the initial level by 16.48%. In addition, the HTF group had significantly higher HDL and lower LDL level compared to the HSF. The administration of tenggulun leaf tea powder for 30 days showed a significant effect on Low-Density Lipoprotein (LDL) and High-Density Lipoprotein (HDL) cholesterol levels, but not on serum Triglyceride (TG) levels. Therefore, the tenggulun leaf tea powder showed a significant effect in improving lipid profile in rats fed with high fat diet.

Abstract

This study aimed to evaluate the effects of different soaking media mineral water, rice-wash water, 1% Ca(OH)₂, and 1% citric acid on the sensory, chemical, and physical qualities of nori produced from a mixture of Ulva lactuca (95%) and Eucheuma cottonii (5%). The results showed that the soaking treatments had a significant effect on the color, aroma, flexibility, crispness, moisture content, and hardness of the nori. The mineral-water treatment produced the best overall performance, with the lowest moisture content (3.01%), the highest flexibility score (3.03), and the highest panelist acceptance score (3.58). The 1% Ca(OH)₂ treatment provided the best green-color stability (a* –7.00) and the lowest hardness (9.847 N), whereas the 1% citric acid treatment resulted in the most degraded coloration (a* 2.70) and the highest hardness (21.076 N). Differences among treatments were influenced by pH-driven modifications of polysaccharide structures, ionic interactions, and depolymerization mechanisms. Overall, rice-wash water was identified as the most effective soaking medium for improving the quality of locally produced nori made from U. lactuca and E. cottonii.
