Efficiency of Bioconversion of Coffee Pulp using Hermetia illucens (Diptera: Stratiomyidae) Larvae

In this study, we evaluate the capacity of Hermetia illucens (L.) to degrade coffee pulp, which is a highly contaminating residue and a by-product of processing coffee beans. The larvae were fed with dietary dosages of 60, 100, 160, and 200 mg/larva/day of Coffea arabica (L.) Castillo variety (0.5% caffeine), until they reached pupae stage. With a dietary supply of 100 mg/larva/day, the highest reduction percentage (%R) on a wet basis (62.88%) and efficiency of conversion of ingested food (ECI) (7.89%) were achieved, while with a dietary supply of 160 mg/larva/day the highest weight reduction index (WRI) in a wet basis was achieved (0.85%). Larvae fed 200 mg/larva/day had the highest weight (115.9 mg) and shortest average development time (38.65 days). In this study we were able to define which dietary supplies of 160 and 200 mg/larva/day, allowing for efficient bioconversion of coffee pulp.

Objective: To develop and validate a simple, accurate, and precise HPLC method for the determination of caffeine in green coffee beans (Coffea arabica L.) from three districts of West Java, Indonesia.Methods: The analytical method was conducted using Enduro C-18 (250 x 4.6 mm) column with methanol: water (37: 63) as a mobile phase, the flow rate was 1.0 ml/min, and the detector wavelength was set at 274 nm. The selectivity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision, and system suitability testing were evaluated as the parameters of validation.Results: The retention time of caffeine was 6.36 min. % RSD for precision was 0.192. The linearity of the method was obtained using a concentration range of 1-200 ppm with the correlation coefficient of 0.998. The limit of detection was 9 ppm and the limit of quantitation was 28 ppm. The accuracy was in between 90.723%-102.853%. Caffeine levels from Garut, Pangalengan, and Tasikmalaya were 1.454 ± 0.004%, 1.574 ± 0.082%, and 2.280 ± 0.004%.Conclusion: The proposed HPLC method meets the acceptance criteria of validation parameters and can be applied for routine analysis.

SummaryWhen coffee trees have a good supply of nitrogen they are less affected by drought. Explanation and evidence are presented. Trees treated with extra nitrogen contained more adenosine triphosphate, aqueous protein and ‘bound water’.Such N-rich trees exhibited lower transpiration rates than trees relatively poor in N when water supply was limiting. They had lower stomatal density and water saturation deficit values. Leaves maintained higher chlorophyll and turgidity. The conclusion is that nitrogen increases the drought-resisting capacity of coffee trees. This aspect was clearly reflected in yield, as nitrogen-rich trees produced more coffee beans.
