Abstract

Butterflies are a group of insects belonging to the order Lepidoptera, commonly known as scale-winged insects. This study examines the kinship relationships of butterfly species (Lepidoptera) based on morphological and morphometric characters in Malonas Village, Dampelas District, Central Sulawesi, an area that has not been previously documented. The objectives of this study were to identify butterfly characters through morphological and morphometric analyses and to construct kinship patterns that reflect the level of phylogenetic similarity among butterfly species. The research was conducted using a descriptive exploratory method. Sampling was carried out across all areas of Malonas Village, including residential areas, rivers, forests, and plantations, using a roaming survey method with free collection techniques, resulting in 10 butterfly species with a total of 30 individuals. Morphological and morphometric analyses included measurements of wing dimensions and major body parts. Data were analyzed using Principal Component Analysis (PCA) and the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) to determine kinship patterns. The UPGMA analysis showed that all species had a relatively high level of similarity, with a similarity value of approximately 0.78, indicating close relationships among species. PCA results revealed that two principal components (PC1 and PC2) explained 67.0% of the total morphological variation, accounting for 45.3% and 21.7%, respectively. Loading plots indicated that morphometric characters related to wing size and proportions were the main contributors to the formation of the principal components. Biplot graphs demonstrated species grouping based on similarities in morphological and morphometric characters, as well as positive correlations among variables within the same quadrant. The results of this study confirm that wing morphometric characters play an important role in explaining morphological variation and phylogenetic relationships of butterflies in Malonas Village.

Abstract

Millipedes (Diplopoda) play an important role in forest ecosystems, particularly in the decomposition of organic matter and the recycling of nutrients, thereby contributing to soil fertility and ecosystem stability. This study aimed to determine the abundance and distribution patterns of millipedes (Diplopoda) in Wera Nature Recreation Park, Balumpewa Village, West Dolo District, Sigi Regency, Central Sulawesi. The research was designed as a quantitative descriptive study. Sampling was carried out using an exploratory survey method combined with hand collection techniques at three observation stations. These stations were selected using purposive sampling based on differences in environmental characteristics and habitat conditions. Data collection was conducted in three repetitions at two-week intervals to obtain representative data on millipede communities. In addition to species collection, measurements of physical environmental parameters were also performed, including light intensity, soil pH, air temperature, and humidity, as these factors are known to influence the presence and distribution of soil macrofauna. The results showed that six millipede species were recorded, belonging to three orders and three families. The average environmental conditions at the study site included a light intensity of 722.2 lux, soil pH of 6.8, temperature of 28.2°C, and humidity of 76.7%. These conditions indicate a habitat that is relatively less optimal for millipede populations. The species abundance index was classified as low, suggesting limited population sizes within the study area. However, the Relative Abundance Index (RAI) revealed variation among species, with two species categorized as having high relative abundance, one species moderate, and three species low. Analysis using Morisita’s Index and the Standardized Morisita Index (Ip) demonstrated that all recorded species exhibited a clumped distribution pattern. This distribution suggests that millipedes tend to concentrate in specific microhabitats that provide suitable moisture, shelter, and food resources. Overall, the findings indicate that unstable environmental conditions may restrict millipede distribution, causing them to utilize only particular microhabitats that meet their ecological requirements.

Abstract

Escherichia coli is a pathogenic bacterium that has the potential to contaminate food. Certain strains of E. coli exhibit pathogenic properties and may cause infections in hosts. The presence of pathogenic bacteria in food is a critical concern in food safety. This study aimed to identify the presence of E. coli in gado-gado sold in the canteens of Tadulako University. This research employed a descriptive exploratory laboratory approach. Samples were collected from five different canteens using random sampling techniques. Microbiological analyses were conducted using the Most Probable Number (MPN) method, Total Plate Count (TPC), Gram staining, cultivation on selective Eosin Methylene Blue Agar, and biochemical testing using Triple Sugar Iron Agar. The results showed that the average Most Probable Number was 4,900 MPN /mL of sample, while the Total Plate Count averaged 35,800 CFU/mL. This TPC value exceeds the standard set by the Indonesian Food and Drug Authority (BPOM) of 104 CFU/g, indicating that the food products do not meet the required health standards. Confirmatory tests on Eosin Methylene Blue Agar showed colony growth with a metallic green sheen and reddish coloration, characteristic of Gram-negative bacilli. Biochemical testing on Triple Sugar Iron Agar yielded positive results consistent with the biochemical characteristics of E. coli. Therefore, the findings confirm the presence of E. coli in the analyzed samples.

Abstract

The Maleo (Macrocephalon maleo) is an endemic bird species found in Central Sulawesi, Indonesia. This species belongs to the order Galliformes and is distinguished by a prominent black, hard casque on its head, an orange beak, predominantly black plumage, and yellowish facial skin. The Maleo exhibits a unique reproductive strategy, as it does not incubate its eggs directly. Instead, it buries them in loose sandy soil that is naturally heated by geothermal activity. According to the 2021 assessment by the International Union for Conservation of Nature (IUCN), the Maleo is classified as Critically Endangered under criteria A2cd+4cd (Version 3.1) of the IUCN Red List. This study aimed to describe the characteristics of Maleo nesting habitats in Bukit Jaya Village, Banggai Regency, in order to support the conservation of suitable in situ breeding and nesting environments. The study employed a descriptive qualitative approach, focusing on direct field observations and literature review. Sampling stations were determined using an exploratory survey method, in which sites were purposively selected based on habitat characteristics to observe Maleo nesting conditions and the surrounding vegetation. Data collected included nesting-hole depth and width, temperatures inside and outside the nesting holes, sand surface temperature, and humidity. Measurements were conducted three times daily at 08:00, 13:00, and 17:00. The results showed that: (1) nesting-hole depth ranged from 43 to 46 cm, with an average of 44.4 cm; (2) nesting-hole width ranged from 47 to 53 cm, with an average of 50 cm; (3) between 08:00 and 17:00, the average temperature inside the nesting holes was 31°C, the average temperature outside the holes was 35.74°C, the average sand surface temperature was 36.2°C, and the average relative humidity was 72.62%; and (4) the nesting habitat in Bukit Jaya Village was characterized by diverse vegetation growth forms, including trees, shrubs, herbs, and climbing plants (lianas). A total of 16 plant species belonging to 12 families were identified within the nesting habitat. The protection of nesting habitats should be continuously strengthened to help prevent the extinction of this valuable and iconic bird species.
