Crop cabbage worm (Crocidolomia pavonana) is one of the pests that has a bad effect on the cabbage production in Indonesia. One of the efforts that has been applied to control this pest is by using bayrusil. However, the bayrusil can cause negative effects such as poisoning and environmentally polluting effects. To prevent the undesired effects, it has been developed the use of environmentally friendly insecticide and one of them is the use of insecticidal peptide. Tripsin-modulating oostatic factor (TMOF) and ist analogues is one of the peptides that has an insecticidal activity. The aim of this research is to synthesise a linear tetrapeptide (DPAP) an analogues of TMOF and to test insecticidal activities against crop cabbage worm. A DPAP has been synthesised by Solid Phase Peptide Synthesis on 2-chlorotrytil chloride resin. Fmoc strategy was applied on the synthesis and a combination DIC/Oxime was employed in the coupling reaction.The tetrapeptidyl resin was cleaved by TFA:water:EDT (90:5:5). The peptide was purified by reverse-phase column chromatography and characterized by TOF ES-MS spectroscopy. A linear peptide was biologically tested towards the C. pavonana, showing percentage of mortality values at 1000 ppm.

Published: August 2024

Fatty alcohol (FAOH) can be produced by hydrogenating of fatty acid methyl ester (FAME) using the copper-based catalyst. Copper-Chrom (Cu-Cr) is the best catalyst for high-pressure reaction condition, which is copper (Cu) as the main active component and chrom (Cr) as a promoter. Since Cr is feared to be toxic, one of the best replacement candidates is manganese (Mn). The research aims is to find the kinetic equation of hydrogenation FAME to FAOH using a Cu-Mn commercial catalyst. FAME with methyl laurate and methyl myristate as the main compounds is used as feedstock. The main products are lauryl alcohol and myristyl alcohol. The reaction was carried out in an isothermal continuous fixed bed reactor under conditions of temperature 220 â€“ 240 oC, pressure 50 bar, and liquid hourly space velocity (LHSV) 5-12.5 hr-1. The kinetic equation is determined using the power law model. The FAME hydrogenation on copper - manganese catalyst is the half order reaction. The activation energy value is 86.32 kJ/mol and the Arrhenius constant value is 5.87x106 M0.5/s.

Published: August 2024

O objetivo do estudo foi ajustar equações volumétricas para as espécies Amazônicas Hymenaea courbaril (Jatobá) e Trattinnickia burserifolia (Amescla) e avaliar a precisão das estimativas na comparação com o emprego de um fator de forma geral. Foi realizada a cubagem rigorosa pelo método de Smalian em 70 árvores de cada espécie e coletado os dados de DAP e altura comercial. O critério de seleção para a escolha do melhor modelo volumétrico foi o valor ponderado dos escores estatísticos (VP). Foram separados ao acaso os dados de volume de 20 árvores de cada espécie e aplicado o teste de ANOVA para verificar as diferenças entre os volumes estimados pelas equações e pelo fator de forma. As melhores equações ajustadas foram de Spur (R2aj 0,90) para H. courbaril e Stoate (R2aj 0,96) para T. burserifolia. Os resultados obtidos pela análise de variância apresentaram diferença significativa apenas para a estimativa do volume comercial de T. burserifolia utilizando o fator de forma 0,7. Conclui-se que os modelos matemáticos estimam o volume com maior precisão que o fator de forma 0,7, no entanto é necessário ajustá-los para diferentes espécies e condições edafo-climáticas. Palavras-chave: Equações de volume, fator de forma, espécies nativas, Amazônia. ESTIMATED VOLUME IN TREES OF Hymenaea coubaril and Trattinnickia burserifolia IN NORTHERN MATO GROSSO ABSTRACTThe study objective was to adjust volumetric equations for amazonian species of Hymenaea courbaril (Jatobá) and Trattinnickia burserifolia (Amescla) and see if there is a significant difference in estimating merchantable volume of these species from the equations of volume and form factor (0.7) established by decree 1862 of 04/2009. The cubing was performed by the Smalian method in 70 trees of each species and collected data DBH and commercial height. The selection criterion for choosing the best volumetric model was weighted by the value of statistical scores (VP). Volume data from 20 trees of each species was used the ANOVA to determine differences between the estimated volumes by the equations and the form factor 0.7 were separated randomly. The best equations were adjusted by Spur (R2aj0.90) for H. courbaril and Stoate (R2aj 0.96) for T. burserifolia. The results obtained by the variance analysis showed a significant difference only for the estimated trade volume of T. burserifolia using the form factor of 0.7. It is concluded that mathematical models estimate the volume more accurately than the form factor of 0.7, however it is necessary to adjust them for different species and environmental conditions.
