Abstract

Red onion skin (Allium cepa L.) is often discarded as waste, despite being rich in flavonoids and alkaloids, which possess antioxidant, anti-inflammatory, antimicrobial, and anticancer properties. This study aims to determine the flavonoid and alkaloid content of red onion skin extract using reflux and Soxhlet extraction methods with 96% ethanol as the solvent. The extraction was performed using reflux and Soxhlet techniques, followed by UV-Vis spectrophotometry to quantify flavonoid and alkaloid content. A quercetin standard curve was used to determine flavonoid levels, while a caffeine standard curve was applied for alkaloid content analysis. The Soxhlet method yielded a higher flavonoid content (108.21 mg/g or 10.82%) compared to the reflux method (105.55 mg/g or 10.55%). In contrast, the reflux method resulted in a higher alkaloid content (169.56 mg/g or 16.95%) than Soxhlet extraction (167.0 mg/g or 16.70%). These differences are attributed to the continuous solvent circulation in Soxhlet extraction, which enhances flavonoid solubility, while the lower temperature in the reflux method prevents alkaloid degradation. The findings suggest that Soxhlet extraction is more effective for flavonoid extraction, whereas reflux extraction is better for alkaloid extraction. Given their significant bioactive properties, red onion skin extracts have potential applications in the pharmaceutical, nutraceutical, and food industries. Future research should focus on optimizing extraction techniques and conducting toxicological and pharmacological studies to explore the therapeutic potential of red onion skin extract.

Abstract

This study aimed to identify the species of Lepidopteran predators that prey on soft scale insects (Coccidae) found on coffee plants in Sigi Regency using molecular techniques. DNA was extracted using the modified CTAB method (Doyle & Doyle, 1990). PCR amplification targeted the COI gene using universal primers LCO1490 and HCO2198 with a GeneAmp PCR System 9700. Visualization was done using 1% agarose gel and UV-transilluminator. Sequencing was conducted externally. Data were analyzed using BioEdit 7.2.5, BLAST, BOLD Systems, and MEGA11 software. The DNA sequence of the predator sample showed 97.91% similarity to Autoba rubra based on GenBank and 97.59% in BOLD Systems. Phylogenetic analysis confirmed a close genetic relationship with A. rubra, distinct from Eublemma. Morphological similarities with Eublemma were misleading, highlighting the accuracy of molecular identification. This study is the first to confirm the identity of a Lepidopteran predator of coffee scale insects in Indonesia using molecular techniques, revealing its close relation to Autoba rubra. The results correct previous morphological misidentifications and contribute new data on predator diversity in biological control contexts.

Abstract

Apis dorsata is a giant honeybee species distributed across South and Southeast Asia. Phylogenetic analysis is used to illustrate the evolutionary relationships of organisms through a phylogenetic tree. This study aims to describe the genetic relationships of A. dorsata based on the cytochrome oxidase I (COI) gene. Sampling was conducted using an exploratory method in various regions, followed by DNA isolation, DNA amplification, sequencing, and bioinformatics analysis using GeneStudio, DNASTAR, MESQUITE, and MEGA 11. The results show that phylogenetic analysis using the Neighbor-Joining (NJ) and Maximum Likelihood (ML) methods produced a phylogenetic tree that clearly depicts evolutionary relationships. A. dorsata from Central Sulawesi is more closely related to other A. dorsata species within the same internal cluster, while other species are separated. These findings reveal a clear pattern of genetic relationships among A. dorsata populations.

Abstract

The study aims to identify the main feed source for Apis nigrocincta through the analysis of polent morphology. The study uses explorative descriptive methods with qualitative and quantitative approaches. The focus of this study is the identification of feed source for endemic honeybees of Sulawesi, Apis nigrocincta through the analysis of polent morphology. Through the approach of polent morphology analysis, successfully identified 12 plant species from 9 families that could potentially be feed sources such as, Cucurbita maxima, Clematis viticella, Clematis montana, Pseuderanthemum tropurpureum, Cersicaria odorata, Solamun torvum, Solamun nigrum, Pine mercussii, Piper betle, Piper nigrum, and Galium aparine identification showed the presence of polyn diversity that supports the nutritional needs of bees, and emphasized the importance of local vegetation conservation to maintain the sustainability of the A. nigrocincta population. The results of the study showed that the polen has characteristics such as the polish unit, size, shape, shape on the P and E side, aperture type, as well as exin ornamentation. The polents collected by bees A. nigrocincta come from various types of plants, namely fruits, ornamental plants, vegetable plants, herb plants, and trees. This diversity reflects the flexibility of bees in choosing food sources based on availability in the surrounding environment. The results of the identification of the polymer samples showed that 12 species of plants that are the main feed source for A. nigrocincta bees are sourced from the polen. Each species has different flower characteristics, both in terms of shape and color. Polen diversity indicates that the environment around Jononunu Village has a rich ecosystem with different types of flowering plants.

Abstract

This study aims to analyze the kinship of butterflies (Lepidoptera) based on morphological characters in Pombewe Village, Central Sulawesi. The research method used was the roaming method with free collection technique. Morphological characters observed included antenna shape, wing color and pattern, and body size. Kinship analysis was conducted using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) with the help of Paleontological Statistics software (PAST 4.03). The results identified 13 butterfly species from the Nymphalidae family, namely Euploea redtenbacheri, Euploea algea, Euploea hewitsonii, Danaus genutia leucoglene, Cyrestis strigata, Danaus genutia genutia, Euploea eunice, Vindula erota, Doleschallia polibete, Acraea terpsicore, Ideopsis juventa, Parantica cleona, and Cyrestis paulinus. The relationship dendrogram showed two main clusters with four relationship categories, namely very close relationship (Cyrestis strigata and Cyrestis paulinus, IS = 100%), close relationship (Euploea hewitsonii and Danaus genutia leucoglene, IS = 74.07%), not close relationship (Cyrestis strigata and Euploea eunice, IS = 32.25%).

Abstract

This study aims to analyze the phylogenetic relationships among six species of fiddler crabs (Uca spp.) found in Lalombi Village, Banawa Selatan Subdistrict, Donggala Regency, based on morphological characters. A descriptive-exploratory approach was employed, with purposive sampling to select representative specimens. Eighteen morphometric characters were measured from three individuals of each species: U. triangularis, U. perplexa, U. dussumieri, U. annulipes, U. tetragonon, and U. bellator. Data were analyzed using Principal Component Analysis (PCA) and UPGMA clustering with the aid of PAST software version 4.03. The PCA results revealed that carapace length (CL), anterior carapace width (ACW), and posterior carapace width (PCW) contributed significantly to total morphological variation. Cluster analysis indicated a close phylogenetic relationship between U. tetragonon and U. triangularis, as well as between U. perplexa and U. bellator. U. annulipes appeared intermediate between the two groups, suggesting a moderate level of relatedness. In contrast, U. dussumieri formed a distinct branch, likely due to its markedly larger body size compared to the other species. These findings affirm that morphometric characters are valuable in elucidating phylogenetic relationships within the genus Uca and support taxonomy based on morphological traits.
