Abstract

Biological observations and life cycle studies of Euploea netscheri Snellen, 1899 on Hoya species were conducted at Yadikap Garden, Arso 2, Keerom, Papua, Indonesia, from June to August 2024.  Eggs laid by female butterflies on Hoya leaves were observed to record hatching time and the duration of the egg stage. Additionally, the total number of larval instars, the duration of each instar, and the duration of the pupal stage until emergence of the imago were documented. Measurements of the length of eggs, larvae, pupae, and adult butterflies were carried out using a caliper. The behavior and morphological characteristics of each larval instar, as well as those of the pupae and adults, were observed and recorded. Female E. netscheri butterflies were found to lay eggs on the leaves of Hoya globulifera and H. pachiphylla. The species completed its life cycle in approximately 22–25 days, consisting of an egg stage of about 3 days, a larval stage of 12–14 days, a pre-pupal stage of 1 day, and a pupal stage lasting 6–7 days. The results of this study provide the first record of the distribution, biology, and life cycle of E. netscheri in Keerom, Papua. New information is also presented regarding its larval host plants, namely H. globulifera and H. pachiphylla.

Abstract

The prevalence of Human Immunodeficiency Virus type 1 (HIV-1) in Papua is increasing. One of the contributing factors is antiretroviral therapy (ART) treatment failure. Mutations in the reverse transcriptase (RT) gene have been shown to alter the structure of RT, leading to resistance to nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs). This study aims to identify mutations in the RT coding gene, evaluate their impact on the effectiveness of RT inhibitors, and determine the frequency of HIV resistance to RT inhibitors among people living with HIV (PLWHA) in Papua and West Papua. Analysis of mutations, resistance, and subtypes was conducted using the Stanford HIV drug resistance database. Subtype classification was validated using COMET, NCBI, and GENE2PONE. YASARA and FOLDX were used to construct RT mutant protein structures. Molecular docking was carried out using Autodock and PYRX, while visualization was performed using PyMOL and Discovery Studio. In this study, the frequency of HIV resistance among subjects was 28.57% for NRTI-only resistance and 57.14% for combined NRTI and NNRTI resistance. The most common NRTI-associated mutations were S68G, M184V, K65R, V75M, and L74I, while the most common NNRTI-associated mutations were K103N, G190A, P225H, K238T, and Y188L. The presence of these mutations altered binding affinity and molecular interactions between RT inhibitors and RT, thereby reducing the effectiveness of RT inhibitor drugs in studied population.

Abstract

Softshell turtles are freshwater turtles with soft carapaces. Their habitat includes freshwater bodies such as rivers and swamps in tropical and subtropical regions. Data on softshell turtle species and their potential habitats in the freshwater ecosystems of the Special Region of Yogyakarta have not been well documented. Based on information from local residents, a softshell turtle population occurs in Sidorejo Village, Lendah, Kulon Progo, Special Region of Yogyakarta. Accordingly, this study aimed to examine the species and potential habitat of softshell turtles in Sidorejo Village, Lendah, Kulon Progo, Special Region of Yogyakarta. Sampling was conducted from 2 February to 17 April 2020 in Kedung Ingas Stream, Sidorejo Stream, and Andong Stream using the Purposive Sampling method. The results showed that the softshell turtle species found was Amyda cartilaginea. The habitat was characterized by shallow streams with depths of 20–70 cm and widths of 150–250 cm, muddy substrates with leaf litter, clear water available throughout the year, calm currents, and riparian vegetation with canopy cover such as water apple, guava, gayam, thorny bamboo, apus bamboo, and lempeni. Softshell turtle nests were characterized by their location under trees, fragments of crab shell in front of the nest cavity, small bubbles in front of the cavity, nest forms resembling cavities in soil or solid rock, and isolated nest sites. These three streams are potential habitats for softshell turtles.

Abstract

The local people of Biak Regency use the Sampare Leaf (Glochidion sp.) to cure malaria and reliefe fever. This plant contains flavonoid compounds, alkaloids, saponins, and tannins that can act as antipyretics. This study aims to determine the antipyretic activity and the most effective dosage of Sampare leaf extract as an antipyretic. The research method was a laboratory experimental. The antipyretic testing method used is peptone-induced fever. A total of 30 mice were divided into 6 treatment groups. The inducing solution, peptone, is induced subcutaneously, and the test solution is administered orally. The results showed that Sampare leaf extract had a percent antipyretic power, namely at 150mg/kgBW of 30.17%, a dose of 200mg/kgBW of 49.66%, and a dose of 250mg/kgBW of 70.80%. The ANOVA test showed that the 250mg/kgBW extract treatment group and the 200mg/kgBW dose with the positive control group has no significant difference, so it can be concluded that the 250mg/kgBW extract dose is an effective dose that provides a good antipyretic effect.

Abstract

Infection in stroke patients is a significant health problem that is associated with poor prognosis and increased treatment costs. This infection can intensify immune system dysregulation, worsen the risk of cognitive decline, and increase mortality and neurological disability. This study aimed to evaluate predictors influencing clinical outcomes in ischemic stroke patients with infectious complications. The study used a cross-sectional design. Retrospective data were collected from medical records at Jayapura Regional Hospital for the period from January 1, 2023, to May 31, 2025. The study subjects were all patients with ischemic stroke who received antibiotics. Clinical outcomes were evaluated based on clinical improvement, defined by vital signs within the normal range, symptom improvement within three to five days after antibiotic administration, and improvement in laboratory values to within the normal range. A total of 50 patients were included after meeting the study inclusion criteria. The results showed significant relationships between risk factors such as hypertension, kidney failure, respiratory tract infection (pneumonia), and rational antibiotic use, with p-values of 0.007, 0.016, 0.023, and 0.007, respectively, and the clinical outcomes of ischemic stroke patients with infectious complications. Multivariate analysis showed that the factors influencing clinical outcomes were hypertension (OR= 7.292; 95% CI 1.510–35.202; p= 0.013), kidney failure (OR= 1.565; 95% CI 0.027–0.810; p= 0.028), respiratory tract infection (pneumonia) (OR= 5.760; 95% CI 1.147–28.920; p= 0.033), and rational antibiotic use (OR= 7.292; 95% CI 1.510–35.202; p= 0.013). Monitoring risk factors in post-infectious ischemic stroke patients is therefore essential. Pharmacists can play an important role in monitoring patients’ clinical conditions to prevent post-stroke complications by paying close attention to patient risk factors.

Abstract

Thermophilic bacteria are able to survive in extreme environmental conditions with high temperatures, generally ranging from 45–80°C. Thermophilic bacteria are also capable of producing protease enzymes. This study aimed to isolate and identify thermophilic bacteria from the Mariarotu hot spring, Yapen Islands Regency, Papua. The method used in this study was a survey followed by laboratory identification. Water samples were collected from two hot spring points with temperatures of 39–49°C. A total of six isolates were obtained and characterized based on macroscopic, microscopic, and biochemical tests. Based on this characterization, all isolates belonged to the genus Bacillus. These results indicate that the Mariarotu hot spring has potential as a habitat for thermophilic bacteria producing thermostable enzymes with possible applications in biotechnology. Further molecular-based studies are required for more accurate species identification.

Abstract

The increasing generation of organic waste, particularly from household sources that are not properly managed, can have negative environmental impacts. One innovative solution is the utilization of waste for eco-enzyme production through fermentation, resulting in a liquid organic fertilizer product. On the other hand, arbuscular mycorrhizal fungi (AMF) are recognized as biological agents (biofertilizers) that can enhance plant nutrient uptake through mutualistic symbiosis with plant roots, thereby improving plant growth performance. This study aimed to evaluate the effectiveness of the combination of AMF and eco-enzyme on the growth of water spinach (Ipomoea aquatica) using a hydroponic system. The study employed a completely randomized design (CRD) with several treatments, namely: (1) control (without fertilizer), (2) positive control (AB-Mix chemical fertilizer), (3) eco-enzyme (liquid organic fertilizer), and (4) a combination of AMF + eco-enzyme, each with three replications. The results showed that eco-enzyme application did not have a significant effect. Although the addition of AMF and eco-enzyme resulted in plant height, leaf number, leaf area, root length, fresh weight, and dry weight, these responses were not superior to the control. Although the percentage of AMF colonies was high in I. aquatica, the use of AB-Mix fertilizer, either alone or in combination with AMF, still performed better than eco-enzyme.

Abstract

Goatfish (Upeneus sp.) is a marine fish commonly sold in traditional markets and widely consumed by the community. However, fish sold in markets may carry parasites that can potentially pose health risks to consumers. Therefore, parasite identification is necessary to provide information regarding parasite occurrence in marketed fish. In this study, eight goatfish samples obtained from the Asem Traditional Market, Surabaya, Indonesia, were examined using macroscopic and microscopic methods. The results showed that 37.5% of the samples were infected with Anisakis sp., with a total of 15 larvae and an average intensity of five larvae per infected fish. The larvae were found in the digestive organs and exhibited distinctive morphological characteristics, including a boring tooth on the anterior end and a mucron on the posterior end, which support the parasite’s invasive ability. These findings indicate a potential health risk to consumers, particularly if the fish is consumed raw or undercooked. Prevention can be achieved through proper post-harvest handling and adequate cooking temperatures to ensure the larvae become non-infective.

Abstract

Industrial activities along the Citarum River, West Java, have resulted in serious heavy metal contamination, causing negative impacts on aquatic ecosystems and human health. Bioremediation using indigenous bacteria with multi-metal resistance offers an efficient and environmentally friendly solution because these bacteria are directly obtained from contaminated environments and are resistant to several heavy metals simultaneously. This study aimed to isolate and characterize indigenous bacteria from the Citarum River that are multiresistant to a mixture of four heavy metals, namely nickel, lead, copper, and cadmium. The bacteria were isolated using the spread plate method on Luria–Bertani Agar supplemented with a mixture of those heavy metals at a concentration of 1 mM. The isolates were purified by the streak plate method and characterized based on colony morphology and cell morphology through Gram staining. The results showed that 24 bacterial isolates were successfully obtained, all of which were able to grow in a 1 mM mixture of nickel, lead, copper, and cadmium. Morphological characterization revealed diverse colonies dominated by yellow, white, and brown pigmentation, with circular shapes and smooth margins. Gram staining showed that all isolates were Gram-negative bacteria. A total of 16 isolates exhibited darker pigmentation, ranging from dark brown to blackish, when cultivated on heavy-metal-containing media. Dark-colored colonies indicate intensive interactions through biosorption and bioprecipitation mechanisms, resulting in the formation of insoluble compounds such as metal sulfides on the cell surface.

Abstract

MTNR in Pangalengan, West Java, is a conservation area with high biodiversity that is increasingly pressured by tourism and agricultural activities, which may affect air quality. This study aimed to examine the relationship between air quality and lichen diversity as bioindicators of air pollution. A descriptive exploratory method was applied at four site types representing different levels of human activity: forest, roadside, plantation, and tourist areas. The results showed that microclimatic conditions and air quality at all sites were classified as good according to Government Regulation No. 22/2021. However, lichen diversity and thallus composition varied among sites in response to environmental conditions. Crustose lichens dominated roadside and plantation areas with higher environmental stress, while foliose and fruticose lichens were more abundant in forest areas characterized by lower temperatures, higher humidity, and minimal pollution. The presence of sensitive species such as Usnea sp. and Ramalina sp. indicated superior air quality in forest sites. In conclusion, lichen distribution reflects an air quality gradient across the study area, confirming the effectiveness of lichens as reliable bioindicators for ecological monitoring in conservation areas.
