Abstract

The importance of food security as part of the Sustainable Development Goals (SDGs), with a focus on local upland rice varieties from Lampung that are drought tolerant but have limitations in seed viability and vigor after storage. The study aims to evaluate the effect of magnetic field exposure on the viability and vigor of upland rice seeds. The method used involves exposing the seeds to a magnetic field for durations of 3, 7, and 11 minutes, followed by measuring parameters such as germination percentage, mean germination time (MGT), coefficient of velocity of germination (CVG), and vigor index. The results showed that magnetic field exposure for 3 minutes produced the best results in several parameters, although not all differences were statistically significant. The magnetic field has the potential to improve the quality of upland rice seeds, but the optimal duration of magnetic field exposure cannot yet be determined

Abstract

Jatropha multifida L. has been used as a traditional remedy for fresh wounds. Its bioactive compounds, including flavonoids, alkaloids, saponins, and tannins, are known for their potential to accelerate wound healing. Research on medicinal plants continues to advance in order to develop more practical pharmaceutical formulations. This study aimed to assess the effectiveness of Jatropha multifida L. leaf extract gel on incision wound healing in Mus musculus and to identify the optimal concentration. A laboratory experimental method with a Completely Randomized Design was used, consisting of five treatments: negative control (no gel), positive control (Bioplacenton), and extract gel concentrations of 15%, 30%, and 45%, each replicated three times using 15 male mice. Daily observations over 25 days included measurements of wound length, redness, scab formation and detachment, and overall wound closure. Data were analyzed using ANOVA to determine differences among treatment groups. One-way ANOVA results showed a significance value of < 0.05, indicating a meaningful effect on wound reduction. The 45% gel concentration demonstrated the highest effectiveness in promoting wound healing. This outcome is linked to the flavonoid content of Jatropha multifida, which supports vasodilation, collagen synthesis, and the strengthening of collagen fibers during the healing process.

Abstract

Carbon dioxide (CO2) is one of the air polluting gases that can cause various health problems if accumulated indoors. Therefore, finding solutions to capture CO2 indoors is important. One of the efforts to reduce CO2 is by placing microalgae as CO2 capture agents in photobioreactors. This study aims to produce a photobioreactor based on microalgae Chlorella vulgaris, analyse cell density, and measure CO2 absorption by microalgae in the photobioreactor. In this study, cultivation was carried out with continuous lighting, microalgae cell density was calculated using a haemocytometer observed under a microscope, and determination of dissolved CO2 levels using the acid-base titration method in Walne medium. The results showed that a block-shaped photobioreactor with a size of 10×10×27.5 cm and a thickness of 2 mm can be a solution to capture indoor CO2 gas. The density of microalgae cells in the photobioreactor was the highest at 4.9 107 (cells/mL), indicating active photosynthesis. The results also show that the photobioreactor has the ability to capture CO2 gas in the room which is characterised by an increase in dissolved ΔCO2 levels reaching 139.39 mg/L.

Abstract

Hypertrophic Cardiomyopathy (HCM) is a common and clinically significant cardiomyopathies affecting felines characterized by excessive thickening of the left ventricular myocardium and decreased systolic pressure. This report describes the case of a 9-year-old, 4 kg, female Persian cat presented with dyspnea, anorexia, and lethargy. On physical examination, the normal rectal temperature, slight pallor mucous membranes, increases capillary refill time with respiratory distress were observed. Auscultation of the thorax revealed arrhythmia. Blood pressure and mean arterial pressure (MAP) indicated hypertension. Serial blood counts were consistent with anemia, eosinopenia and monocytosis suggesting chronic stress. Thorax radiograph revealed the heart enlargement through vertebral heart scale (VHS) and cardiothoracic ratio (CTR) score measurement. Complementary diagnostic test with biomarker pro-Brain Natriuretic Peptide (proBNP) confirmed the diagnosis of HCM. This case report describes the clinical findings, cardiac evaluation, and HCM diagnosis in a geriatric cat.

Abstract

Eco-enzyme solutions are commonly utilized as disinfectants, cleaners, and liquid fertilizers; however, their potential as substrates for biogas production remains underexplored. This study evaluated the methane (CH₄), carbon dioxide (CO₂), nitrogen (N₂), pH, temperature, and gas pressure generated from eco-enzyme–based anaerobic fermentation supplemented with cow manure as a microbial starter. A quantitative experimental design with five treatments and direct observational measurements was employed, and data were analyzed descriptively. Results showed that methane production was generally low, with the highest concentration observed in treatment P5 (2.889%). The highest gas pressure was also recorded in P5 (70 mL). Nitrogen dominated the gas composition (95.875–99.669%), while CO₂ ranged from 0.237 to 4.125%. These findings indicate that eco-enzyme combined with cow manure produces low CH₄ levels, suggesting that further optimization of substrate composition and fermentation conditions is needed to enhance biogas quality.

Abstract

Microplastics pose serious threats as they can  contaminate various ecosystems, ranging from seawater surfaces, beach sands, freshwater sediments, coastal sediments, to deep-sea environments. Their presence, particularly in coastal areas, exerts significant negative impacts on ecosystem balance and human health. This study aimed to analyze the types and abundance of microplastics in seawater and sediments of South Lampung’s coastal area, measure related environmental parameters (BOD, COD, pH, temperature, and current velocity), and provide baseline data to support strategies for pollution control. The research was conducted using an experimental method at six stations located 50–100 meters apart. Water and sediment samples were collected, filtered, separated, and analyzed using Fourier Transform Infrared Spectroscopy (FTIR) to identify polymer types. The results revealed that microplastics were detected at all stations, with dominant polymers including polyethylene (PE), polypropylene (PP), polyester (PES), polystyrene (PS), and smaller amounts of polyamide. Physico-chemical parameters of the waters were generally within acceptable thresholds, although BOD levels at several stations slightly exceeded the quality standards, indicating a relatively high organic load. This study confirms that microplastic pollution has already occurred in the South Lampung coastal area, dominated by polymers originating mainly from anthropogenic activities such as household waste, synthetic textiles, and coastal activities. As such, this research provides an essential initial step in mapping microplastic pollution in the region.

Abstract

The study aims to evaluate the early growth response of mint cuttings (Mentha spicata) to two rooting media: water and soil. The study was conducted at the Biology Laboratory of the Faculty of Science and Technology, UIN Sulthan Thaha Saifuddin Jambi, with a 7-day observation period. The parameters observed included the percentage of cuttings that survived, time to the first leaf, number of leaves, and number of roots. The results showed that mint cuttings in a water medium had better initial growth than those in a soil medium. The average number of roots in water medium was 22.00 ± 15.56, while the average number of leaves in water medium reached 13.50 ± 7.78. The first leaves appeared earlier in the water medium (on the third day). The survival rate of cuttings in both media reached 100%. Thus, water medium can be recommended as a more optimal initial rooting medium for mint cutting propagation before being transferred to a subsequent planting medium.

Abstract

This study aims to develop a novel mathematical framework for understanding evolutionary relationships by applying Category Theory to biological systems. The objective was to formalize phylogenetic classification as a quotient category, providing a unified structural language for genetics, development, ecology, and evolution. This categorical framework provided a rigorous mathematical foundation for theoretical biology, unified disparate subdisciplines, and offered new tools for predicting evolutionary outcomes, classifying organisms, and understanding developmental constraints. The approach suggested that phylogenetic trees were universal quotients emerging from more complex evolutionary networks

Abstract

Antibiotics were essential medicines in Indonesia, and due to the high prevalence of antimicrobial resistance, new sources of antibiotic substances were urgently needed. One of the microorganisms capable of producing novel antibiotics was thermophilic bacteria. This study aims to isolate thermophilic bacteria from Garara Hot Spring that had potential as antibiotic producers. The results indicated that isolate TUA107 exhibited the strongest antimicrobial activity against Escherichia coli and Staphylococcus aureus, with inhibition zones of 6.56 mm and 7.70 mm, respectively. These findings suggested that molecular identification of thermophilic bacteria and metabolomics studies of potential antibiotic-producing isolates from Garara Hot Spring were needed to optimize their potential.

Abstract

Multi organ dysfunction syndrome involves multiple inflammatory receptors that regulate multi-organ damage. This study aims to analyze the structural characteristics of multireceptor inflammasome through the in silico method. The receptors analyzed were TNFR1, IL-1, IL-6, and NLRP3. The structural characteristics analyzed include affinity energy, RMSD, inhibition constants, and amino acid interactions. The results showed that NLRP3 had the most negative affinity energy value compared to others, which was -9,4 kcal/mol and an inhibition constant of 0,237 μM. The validity of the NLRP3 model was confirmed to be very stable with an RMSD value of 1,1709 Å, while other receptors showed a structural deviation of > 6 Å. Amino acid interaction analysis showed that the majority of interactions occur hydrophobic more than other receptors, and there are also hydrogen bonds. Based on the results of the study, it is known that NLRP3 has the best structure in silico, so it can be used as a reference for receptor models in follow-up research related to pathogenesis and anti-MODS drug development studies
