Abstract

Red dragon fruit peels and rosella flower petals are combined with a concentrated sucrose to be processed into jam which has health benefits. These benefits are obtained from the antioxidant content of of both ingredients thatcan prevent degenerative diseases. The purpose of this study was to determine the effect of adding rosella flower extract and the appropriate concentration of sucrose on the chemical, organoleptic , and antioxidant activity of good red dragon fruit peel jam. Based on the test results, the jam with the best quality will also be determined. The experimental design used a factorial completely randomized design with three treatments of rosella flowers; 20, 30, and 40% and the sucrose concentrations were 50, 60 and 70%, and repeated three times. The results showed that the combination of rosella calyx and sucrose jam had an effect on pH, vitamin C, antioxidant activity, color, texture and aroma but had no significant effect on water content, total dissolved solids, reducing sugar and taste. Jam treatment with a concentration of 70% sucrose and 30% rosella flower extract produced the best quality based on chemical, physical and organoleptic parameters.

Abstract

This study was aimed to ascertain how leachate and faecal sludge interacted to affect kailan plant development and yield in inland peat soil. The design used was Factorial Randomised Complete Block Design with 2 factors. The first factor was leachate water consisting of 4 levels, namely L0 (0 mL), L1(150 mL), L2(250 mL), and L3(350 mL), and the second factor was sewage sludge consisting of 4 levels, namely T0 (0 gr), T1(100 gr), T2(200 gr), and T3(400 gr). The results showed that there was a very significant interaction between the application of leachate water and faecal sludge on plant height, leaf area, and fresh weight of plants but there was no interaction between the application of leachate water and faecal sludge on the number of leaves and fresh weight of roots. The optimal interaction of leachate and faecal sludge doses on the growth and yield of kailan plants is in the treatment of leachate at a doses of 150 mL/polybag and faecal sludge at a doses of 200 gr/polybag.
