Abstract

Cucurbita moschata is a medicinal plant that possesses various pharmacological properties, including antidiabetic, antifungal, antibacterial, anti-inflammatory, and antioxidant activities, which are associated with its bioactive compound content. One plant part that has been relatively underutilized is the pumpkin stem, although it has the potential to contain secondary metabolites such as flavonoids and tannins. This study aimed to identify and determine the levels of bioactive compounds in pumpkin stem extract based on stem maturity stages, namely young stems and mature stems, using both qualitative and quantitative methods. Qualitative analysis was conducted through phytochemical screening using color reaction methods with specific reagents to detect flavonoids and tannins. Quantitative analysis was performed using UV-Vis spectrophotometry based on standard calibration curves. The results showed that pumpkin stem extract tested positive for both flavonoids and tannins. Quantitative analysis indicated that the flavonoid content in young stems was 7.22, which was higher than in mature stems (3.00). In contrast, tannin content was higher in mature stems (9.03) compared to young stems (5.02). These differences indicate that flavonoids are more dominant in young tissues with active metabolic activity, whereas tannins tend to accumulate in mature tissues as part of plant defense mechanisms. Based on these findings, it can be concluded that pumpkin stem extract contains flavonoid and tannin compounds with varying levels depending on stem maturity, suggesting its potential as a natural source of antioxidants.

Abstract

Schistosomiasis is a neglected tropical disease caused by trematode worms of the genus Schistosoma and remains a public health concern in several endemic areas of Central Sulawesi, Indonesia. DNA-based molecular approaches have been increasingly applied to support species identification and the analysis of genetic relationships in Schistosoma japonicum. This study aimed to investigate the phylogenetic relationships and genetic variation of S. japonicum based on the mitochondrial 16S rRNA gene. Samples of Oncomelania hupensis lindoensis were collected from endemic areas surrounding Lake Lindu, Central Sulawesi, Indonesia. Detection of S. japonicum was performed using the crushing method, followed by DNA extraction with the GS 100gSYNCTM DNA Extraction Kit. Amplification of the 16S rRNA gene was carried out using the Polymerase Chain Reaction (PCR) technique with the primers LR13107-F and LR12647-R. Sequence data were analyzed using BLAST, MEGA 11, MESQUITE, DNASTAR, GeneStudio, and DnaSP software. Phylogenetic trees were reconstructed using the Neighbor-Joining (NJ) and Maximum Likelihood (ML) methods with 10,000 bootstrap replicates. PCR amplification produced clear and high-quality DNA bands. BLAST analysis revealed query cover values ranging from 99.90% to 100% and sequence identity of 100% with Schistosoma japonicum sequences available in GenBank. Genetic variation analysis indicated low genetic diversity, characterized by two haplotypes, one variable site, haplotype diversity of 0.500 ± 0.170, and nucleotide diversity of 0.00055 ± 0.00015. Nucleotide composition analysis showed that thymine (T) was the most abundant nucleotide (43.53%), and the A+T content (72.14%) was higher than the G+C content (27.87%), a characteristic feature of mitochondrial genomes. Phylogenetic reconstruction using both NJ and ML methods consistently clustered the Central Sulawesi samples with S. japonicum populations from Shanghai and Guangdong, China, with strong bootstrap support values ranging from 99% to 100%. Genetic distance analysis based on the Kimura 2-Parameter model revealed genetic divergence values of 0.00–0.00% among Central Sulawesi samples and between the Indonesian and Chinese populations, indicating very close genetic relationships and high genetic homogeneity. These findings demonstrate that S. japonicum populations in Central Sulawesi exhibit low genetic variation and share close phylogenetic relationships with other Asian populations, providing valuable molecular information to support the development of schistosomiasis surveillance and control strategies in Indonesia.

Abstract

The golden apple snail (Pomacea canaliculata) is a freshwater mollusc species commonly found in rice field ecosystems and is recognized as one of the major pests of rice crops. This species possesses a high adaptive capacity and a rapid reproductive rate, allowing its population to increase rapidly and cause significant damage to rice plants. Nevertheless, the golden apple snail also has ecological roles and potential benefits, including serving as an alternative feed source for livestock and fish, as well as contributing to the decomposition of organic matter in aquatic environments. This study aimed to analyze the population density and distribution pattern of the golden apple snail in the rice fields of Dolago Padang Village, South Parigi District. The research employed a quantitative descriptive approach using a field survey method. Data were collected using a quadrat sampling technique with plot sizes of 2 × 2 m established at three different observation stations. The number of golden apple snail individuals within each plot was counted directly and subsequently analyzed to determine population density and distribution patterns using the Morisita Index. In addition, environmental parameters, including water temperature and pH, were measured. The results showed that a total of 90 golden apple snail individuals were recorded during the study. Population density ranged from 1 to 2 individuals/m², which was categorized as moderate. The distribution pattern of the golden apple snail at all observation stations was classified as uniform, as indicated by Morisita Index values below 1 (Id < 1). Environmental conditions, with temperatures ranging from 27–30°C and pH values between 6.5 and 7.2, were within the optimal range supporting the presence and development of the golden apple snail.

Abstract

Insects are the most diverse group of living organisms, accounting for nearly 80% of all known animal species. They belong to the phylum Arthropoda and exhibit a wide range of morphological characteristics. Insects can be found in almost all habitats, ranging from lush tropical rainforests to harsh deserts, as well as aquatic environments such as rivers and lakes. This study aimed to identify and describe insect species associated with bird's eye chili pepper (Capsicum frutescens L.) in Tudua Village. The research was conducted in October 2025. The study sites were selected using purposive sampling, with three observation plots measuring 10 × 10 m each. Insect samples were collected using a combination of sweeping nets, pitfall traps, light traps, and yellow traps. The collected specimens were identified based on their morphological characteristics up to the order, family, genus, or species level and were analyzed descriptively to determine their ecological roles within the agroecosystem. The results revealed a total of 29 insect species belonging to eight orders: Araneae, Coleoptera, Hemiptera, Orthoptera, Odonata, Lepidoptera, Hymenoptera, and Blattodea. The identified insects exhibited diverse ecological roles, including pests, herbivores, predators, pollinators, and decomposers. Members of the order Hemiptera and some species of Coleoptera were the most commonly encountered pest groups. Meanwhile, Araneae, Hymenoptera, and Odonata functioned as natural predators, Lepidoptera acted as pollinators, and Blattodea served as decomposers. The presence and distribution of insects were influenced by environmental factors such as temperature, humidity, light intensity, and soil pH.

Abstract

Male domestic cats tend to exhibit different behaviors influenced by reproductive hormones, such as aggression, territorial instincts, and relatively high levels of exploratory activity. Sterilization (castration) has been shown to reduce the production of these hormones, which may consequently affect cats' daily behavioral patterns. This study aimed to examine changes in the daily behavior of domestic male cats before and after sterilization (castration). Observations were conducted on 15 cats (A–O), with variables including feeding frequency, sleeping patterns, grooming behavior, play activity, aggressive behavior, social interactions, and physical health. The method employed was direct observation of cat behavior before and after the sterilization procedure. The findings revealed significant behavioral changes following sterilization, including reduced aggression, decreased roaming activity, increased resting time, and more regular feeding patterns. In addition, social interactions with humans and other cats increased, while the cats’ physical condition became more stable. The degree of behavioral change varied among individual cats and was influenced by factors such as breed, age, individual temperament, and the environment in which they were kept. Therefore, sterilization not only plays an important role in population control but also contributes to improved behavioral stability and overall welfare in domestic male cats.

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.

Abstract. Sutrisnawati, Ramadhan A, Trianto M. 2022. Molecular identification of Oncomelania hupensis lindoensis, snail intermediate hosts of Schistosoma japonicum from Central Sulawesi, Indonesia. Biodiversitas 23: 5989-5994. Schistosomiasis is a zoonotic parasitic disease with Oncomelania hupensis lindoensis, intermediate snail hosts of Schistosoma japonicum. The spread of O. hupensis lindoensis snail habitat was found in the three areas of the Napu, Bada, and Lindu Highlands with an infection rate above 1%. Oncomelania hupensis lindoensis  is primarily cryptic species that are morphologically difficult to identify and distinguish from other species. Consequently, it can be confused with the naming of species. One of the molecular approaches that can be used to identify the Oncomelania spp. quickly and accurately is DNA barcoding using the COI mitochondrial gene. However, the research on identifying Oncomelania spp. in Indonesia is still very limited. Therefore, this study aimed to identify six Oncomelania spp. from Napu and Lindu, Central Sulawesi using COI mitochondrial gene as a molecular marker for DNA barcoding. The method used in this study was a Polymerase Chain Reaction (PCR) method with universal primers, LCO-F and HCO-R. The data obtained were then analyzed using GeneStudio, DNASTAR, BLAST, Identification Engine, Mesquite, MEGAX, and BEAST. The analysis was conducted to obtain similarity, genetic distance and reconstruct a phylogenetic tree. The result revealed that all six samples of Oncomelania spp. collected from Napu and Lindu were identified in one species, namely Oncomelania hupensis lindoensis. This research is very important to be carried out regularly periodically so that it can be used as a basis for Schistosomiasis control program data and related sectors to eradicate snails effectively, efficiently, and on target.
