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.
