Abstract

The use of plants for human needs is very high, especially among communities in suburban and rural areas. Communities are highly dependent on forests as their main source of sustenance. The purpose of this study was to determine the use of Nelambo Suon (Bikkia sp.) plant stems among the Yali tribe in Yahukimo Regency, Papua. The method used was a survey, which was conducted through field observations and interviews using questionnaires. This study was conducted in four villages, namely Sabelebi, Muhumu, Kinkun, and Ohena, in the Heriapini District of Yahukimo Regency, Papua Mountains. This study involved 43 respondents consisting of primary informants, key informants, and supplementary informants. The results of the study show that the Bikkia plant is widely used by the Yali tribe in the Papua Mountains. The bark can be used as a remedy for malaria, while the trunk is used to make sehen arrows, suap arrows, and wangkun sticks (for harvesting crops). As many as 88.37% of the community acknowledged that the trunk of this tree is very strong and can be used for various purposes. However, conservation efforts for this plant have not yet been undertaken by the community. Considering that Bikkia sp., found in Yahukimo, is one of several species with limited distribution in the world, conservation efforts are needed.

Abstract

Tropical frontier regions such as Keerom Regency in Papua, Indonesia, face increasing pressure to expand food production under the National Strategic Projects (PSN) for food security. However, the absence of baseline data on soil fertility and water quality constrains the design of sustainable management practices. This study evaluated the temporal variation in soil chemical properties and aquaculture water quality to establish scientific benchmarks for site-specific interventions. Soil samples from chilli pepper (Capsicum annuum) farms were collected across resting, early growth, pre-harvest, and intercropping stages, while water samples from catfish (Clarias spp.) ponds were obtained during larval, grow-out, and harvest phases. Soil pH declined from 6.5 to 4.4, accompanied by reductions in total N, P, and K and a gradual rise in EC, indicating nutrient depletion and increasing acidity. In aquaculture ponds, DO levels decreased while Ammonium and nitrite accumulated during intensive feeding, suggesting excessive organic loading and incomplete nitrification. These results reveal critical limitations in both systems that reduce productivity and environmental resilience. The findings provide essential baseline data for nutrient management, fertilizer optimization, and water-quality control, forming a scientific foundation for future integrated agriculture–aquaculture (IAA) development to strengthen regional and national food-security initiatives in Papua.

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.
