Isolation and testing of antioxidant activity with1,1-difenil-2-pikril hidrazil (DPPH) from ethyl acetate extract ofcocoa pod husk(Theobroma cacao L) has been carried out.Theobroma cacaoextract (TCE) showed highly strong antioxidant activity with IC50 = 8,75 ppm and vitamine C = 6,07 ppm as positive control. Isolation of the active components of TCE by column chromatography using silica gel absorbent 60 mesh ASTM (Merck 774) and the eluent n-hexane: ethyl acetate (9:1), obtained 7 fraction combined (TCE 1 to TCE 7). There are 6 combined fractions having the potential as antioxidants, namely TCE 2 to TCE 7 with a range of IC50 (6,46 ppm – 91,8 ppm). TCE 2 fraction has a very strong antioxidant activity with IC50 = 6,46 ppm. Separation of TCE 2 fraction on silica column chromatography obtained 4 combined fractions (TCE 2.1 to TCE 2.4). The test results of antioxidant activity showed that TCE 2.4 had very strong activity with IC50 = 42,7 ppm.For the TCE 2.2 fraction, preparative TLC was carried out using eluent n-hexane: ethyl acetate (9.5: 0,5) obtained by TCE 2.2.4 isolate with a melting point of 114-120 °C and was a steroid class.

Theobroma Cacao L

Increasing production of cocoa (Theobroma cacao L.) leads to a higher environmental burden due to its solid waste generation. Cocoa pod husk, one of the major solid wastes of cocoa production, contains rich bioactive compounds unveiling its valorization potential. With that in mind, our research aimed to explore the biological and antioxidant activities of aqueous extracts from cocoa pod husks. In this present work, cocoa pod husk was extracted using water and subsequentially partitioned using n-hexane, ethyl acetate, and methanol. The antimicrobial investigation revealed that the ethyl acetate solubles were active against the Staphylococcus aureus, Escherichia coli, and Candida albicans, where at a 20% w/v concentration, the inhibition diameters were 6.62 ± 0.10, 6.52 ± 0.02, and 11.72 ± 0.36 mm, respectively. The extracts were found non-toxic proven by brine shrimp lethality tests against Artemia salina with LC50 scores ranging from 74.1 to 19,054.6 μg/mL. The total phenolic content and total flavonoid content were obtained in the range of 47.44 to 570.44 mg/g GAE and 1.96 to 4.34 mg/g QE, respectively. Antioxidant activities of the obtained extracts were revealed by 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assay with EC50 reached as low as 9.61 μg/mL by the ethyl acetate soluble. Phytochemical screening based on gas chromatography—mass spectroscopy analysis on the sample with the highest antioxidant activities revealed the dominant presence of three phytosterols, namely gamma-sitosterol, stigmasterol, and campesterol.

This study was aims to exploit the potential waste of cocoa pod (Theobroma cacao L.) as a natural acaricide in ticks (Boophilus microplus). The study was conducted with a two-variable completely randomized design (CRD) with two repetitions. The sample does not differentiate between sex, body weight, and length of about 0.8 - 1 cm. Each 5 ticks were treated as follows: treat 1 extract of 10% cocoa pod husk; treatment 2 20% cocoa pod skin extract; treatment 3 30% cocoa pod husk extract; treatment 4 negative control; treat 5 positive controls. In the first variable the tick was treated with methanol extract, while in the second variable the ethanol extract was treated with 10%, 20%, 30% respectively, negative control and positive control. In treatment I used 25 ticks plus treatment II 25 ticks. Each treatment was repeated to avoid data bias so that a total of 100 ticks were used. The results showed that the cocoa pod husk extract had the best killing power at a concentration of 30% with methanol solvent at 6.21 hours while ethanol solvent at 5.91 hours. The use of extraction materials has not been able to compensate for the use of synthetic materials that can kill in minutes.

Theobroma Cacao L

Cocoa pod husk composites for structural applications face a substantial water absorption problem in which the residual tensile, fatigue, and flexural characteristics always exhibit instant deterioration after immersion in water. Unfortunately, there is an absence of sensitivity analysis research on the composite’s water absorption parameters to establish the crucial parameters that may function as drawbacks. Consequently, this study establishes how the sensitivity analysis of the Fickian’s model parameters can be measured using single and joint parametric variations in the water absorbed at saturation, interactive indicator and the response indicator between patterns using experimental data and literature sources. Results revealed that the most sensitive case study was obtained when the response indicator between patterns was varied with the absorbed quantity in time, accounting for 95.24 % (20 out of 21 cases). Accordingly, composite engineers and designers should use the most sensitive parameter to control design features.
