Abstract

The purpose of this study aims to get the best combination of palm oil midrib and coconut midrib in making charcoal briquettes. The study was conducted experimentally using a complete randomized design method consisting of 5 treatments and 3 replications. The treatments in this study were the ratio of palm oil midrib and coconut midrib charcoal as follows: KSK1 (100:0), KSK2 (75:25), KSK3 (50:50), KSK4 (25:75) and KSK5 (0:100). The parameters observed were density, water content, ash content, vapour content, bound carbon content and heating value. The result of palm oil midrib and coconut midrib shells had a significant effect on density, water content, ash content, vapour content, bound carbon content and heating value. Based on the results of the analysis, the best treatment in this study were KSK4 of palm oil midrib and coconut midrib (25:75) with a density of 0,58 g/cm3, water content 5,82%, ash content 5,87%, evaporating content 15,01%, bound carbon content 79,12%, and heating value content 6596,65 cal/g.

Abstract

This study aims to obtain antioxidant activity and the best quality of mango leaves herbal tea based on the location of the leaves on branches. The research has been experimentally using a completely randomized design (CRD) with 4 treatments and 4 replications, so that 16 experimental units obtained. The treatments used were P1: Leaf shoots, P2: Young mango leaves (numbers 1-3 after the shoot), P3: Old mango leaves (numbers 4-6 after shoots) and P4: Oldest mango leaves (numbers 7-9 after shoots). Observations made on mango leaf herbal tea were water content, ash content, total phenol, antioxidant activity and sensory assessment. The data obtained from the observation analyzed statistically using analysis of variance (ANOVA) with IBM SPSS software version 23. The results showed that the best treatment for mango leaf herbal tea based on the location of the leaves on the selected branches was the P1 (leaf shoot) treatment because it had very strong antioxidant activity. The antioxidant activity of P1 treatment with IC50 value was 25,91ppm, total phenol was 25.90%, water content was 9.95%, and ash content was 2.42%, with a descriptive green-yellow color, slightly mango leaf-scented and slightly bitter taste.
