Abstract

Salinity is a major abiotic constraint that limits rice establishment, particularly during germination when seedlings are physiologically vulnerable. This study investigated the effect of auxin priming on germination performance and early seedling growth of IR64 rice exposed to 100 mM NaCl, and identified the most effective auxin concentration. The experiment was conducted using a Completely Randomized Design with five treatments: non-primed seeds and auxin priming at concentrations of 0, 25, 50, and 100 ppm, each with three replications. Statistical analysis was performed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test at the 5% significance level. Parameters observed included germination percentage and rate, root and plumule length, total seedling length, vigor index, fresh and dry weight, and lipid peroxidation. Auxin priming significantly enhanced germination rate, seedling growth, vigor index, and biomass accumulation, while reducing lipid peroxidation under saline conditions. Among the treatments, P3 exhibited the most consistent improvement under salinity stress, whereas P1 showed the highest overall growth under non-stress conditions. These findings indicate that appropriate auxin priming can improve the early physiological performance of rice seedlings under salt stress.

Abstract

Dyspepsia syndrome is a prevalent health issue that can disrupt daily routines and diminish overall productivity. This study aims to evaluate the correlation between smoking intensity, coffee intake, and sleep quality with the occurrence of dyspepsia syndrome at the Mataram City Regional General Hospital (RSUD). Utilizing an analytical observational method with a cross-sectional framework, this quantitative research involved a sample of 107 patients selected via simple random sampling. Data analysis was conducted through univariate and bivariate methods using the Chi-square test. The findings reveal a statistically significant association between smoking degree (p=0.000) and coffee consumption (p=0.000) with the incidence of dyspepsia. In contrast, no significant relationship was observed regarding sleep quality (p=0.348). In summary, smoking habits and coffee consumption are major contributors to dyspepsia syndrome, whereas sleep quality is not a primary factor. Future studies are encouraged to investigate additional variables, such as psychological stress and dietary patterns, to provide a more comprehensive understanding of dyspepsia risk factors.

Abstract

Glaucoma is a group of optic neuropathies characterized by progressive damage to the optic nerve, often associated with increased intraocular pressure. Secondary glaucoma occurs when elevated intraocular pressure results from other ocular or systemic diseases such as hypertension, diabetes mellitus, or cataract. This study aims to determine the relationship between hypertension, type 2 diabetes mellitus, and cataract with the incidence of secondary glaucoma at the Eye Hospital of West Nusa Tenggara Province. Using a cross-sectional design, this quantitative research involved patient data collected from medical records. Data were analyzed using univariate and bivariate methods with the Chi-square test. The results showed significant associations between hypertension (p-value < 0.05), type 2 diabetes mellitus (p-value < 0.05), and cataract (p-value < 0.05) with the incidence of secondary glaucoma. In conclusion, hypertension, type 2 diabetes mellitus, and cataract are significantly correlated with the occurrence of secondary glaucoma. Further research is recommended to include additional factors such as age, sex, and medication history to better understand the risk factors for secondary glaucoma.

Abstract

Gene editing has emerged as a transformative approach in biomedical science, enabling precise modification of genomic sequences to investigate gene function and develop novel therapeutic strategies. Among available technologies, CRISPR-Cas9 has revolutionized genome engineering due to its simplicity, programmability, high efficiency, and cost-effectiveness. This review examines the mechanisms, biomedical applications, limitations, ethical considerations, and future prospects of CRISPR technology, with particular emphasis on its relevance to gene therapy in Indonesia. CRISPR has demonstrated significant potential in treating monogenic disorders such as β-thalassemia and sickle cell disease, advancing cancer research through gene targeting and immunotherapy, and enabling innovative antiviral strategies and molecular diagnostics. These applications highlight its potential to provide precise and potentially curative therapies. However, several challenges remain, including off-target effects, limitations in delivery systems, biological complexity, and uncertainties regarding long-term safety. Ethical concerns, particularly related to germline editing, informed consent, and social equity, further complicate its clinical application. In Indonesia, CRISPR development is still at an early stage, with applications largely limited to research settings. Key challenges include limited infrastructure, insufficient expertise, evolving regulatory frameworks, and low public awareness. In conclusion, CRISPR holds strong potential for advancing gene therapy in Indonesia, but its successful implementation requires strengthened regulation, improved infrastructure, capacity building, and greater public engagement to ensure safe and ethical use.

Abstract

A study entitled Blood Group Characteristics of Students of the Biology Education Study Program, FKIP, University of Mataram, Class of 2023/2024 has been conducted. This study aimed to: (1) determine the characteristics of blood groups among students of the Biology Education Study Program, FKIP, University of Mataram, class of 2023/2024; and (2) enhance students’ understanding in the Human Anatomy and Physiology course, particularly regarding blood groups. The determination of blood groups is crucial in the medical field, as incompatibility between donor and recipient blood groups during transfusion can trigger serious immune reactions, such as hemolysis, anaphylactic shock, and even death. This research employed a descriptive, non-experimental design, in which the researchers collected basic information on students’ blood groups without conducting laboratory examinations. Data were collected online using Google Forms as the primary instrument. Based on the research results, the distribution of blood groups was as follows: O = 49.22% (63 students), B = 28.91% (37 students), A = 18.75% (24 students), and AB = 3.13% (4 students). It can be concluded that the blood group distribution among Biology Education students of the 2023/2024 cohort shows a dominant pattern of blood group O. Out of a total of 128 respondents, blood group O accounted for 49.22% (63 students), followed by blood group B at 28.91% (37 students), blood group A at 18.75% (24 students), and blood group AB at 3.13% (4 students).

Abstract

Bruchid beetles are primary pests of stored pulses, causing significant post-harvest losses. Callosobruchus maculatus (F.) and Callosobruchus chinensis L. are the most common species in tropical and subtropical regions, often co-occurring in storage. This study aimed to evaluate the temperature-dependent life cycle parameters of C. maculatus and C. chinensis infesting mungbean (Vigna radiata L.) seeds. The life cycle of both species was observed under two different conditions: controlled (27 ± 1°C, 65 ± 5% RH) and room temperature: uncontrolled (34 ± 4°C, 70 ± 5% RH). Three experimental sets were maintained, each with 10 replicates in completely randomized design. Life cycle duration was recorded, and data were analyzed using descriptive statistics to determine mean durations. Under controlled conditions, C. maculatus and C. chinensis completed their life cycles in 33.40–39.80 days (mean 36.84 ± 1.61) and 31.30–36.70 days (mean 34.20 ± 1.23), respectively. At room temperature, development accelerated, with durations of 28.53–32.70 days (mean 30.84 ± 1.17) and 26.30–31.80 days (mean 29.32 ± 1.55), respectively. Higher temperatures shorten the life cycle of both beetle species, potentially increasing infestation rates. These findings highlight the need for temperature management and timely monitoring in stored mungbean to reduce bruchid damage and improve storage outcomes.

Abstract

Wadaslintang Reservoir is a multipurpose reservoir used for power generation, irrigation, capture fisheries, and fish farming using a floating net cage (KJA) system. Intensification of this utilization has the potential to increase pressure on water quality and the sustainability of fish resources. This study aims to evaluate the condition of water quality, phytoplankton community structure, composition and size of fish catch, and their relationship to KJA cultivation activities in Wadaslintang Reservoir. The study was conducted through measuring physicochemical parameters of water at six observation stations, phytoplankton identification, analysis of fish catch composition, measurement of tilapia size, and collection of secondary data regarding KJA cultivation activities. The results showed that most water quality parameters, such as dissolved oxygen, temperature, nitrate, and ammonia, still met the quality standards for class III waters. However, the total phosphate concentration at several stations exceeded the quality standards, accompanied by relatively low clarity and the dominance of phytoplankton from the Chlorophyta and Cyanobacteria groups with a moderate diversity index (H' = 1.78), which indicates the presence of nutrient pressure leading to eutrophic conditions. The catch composition is dominated by tilapia (75.68%), with sizes that are generally still relatively small compared to mature gonad size. Production from marine cage cultivation is also dominated by tilapia (97.91%), potentially increasing nutrient loads if management is not adjusted to environmental carrying capacity. The results of the study indicate that Wadaslintang Reservoir is still suitable for fisheries, but requires capacity-based aquaculture management, increased feed efficiency, and regular water quality monitoring to maintain ecosystem sustainability.

Abstract

Feed is a major component in livestock production; however, the availability of forage is often constrained by limited land resources and seasonal fluctuations. A leguminous plant, alfalfa (Medicago sativa L.) is sometimes referred to as the "queen of forages" because of its abundant protein and great nutritional value. Forage production might be improved by using the plant growth regulator gibberellin (GA3). The purpose of this research was to find out how much of an impact GA3 has on the pace of growth of alfalfa fodder, taking into account factors like germination time, plant height, and biomass output (both fresh and dry weight). P0 (control group without GA3), P1 (GA3 150 ppm), and P2 (GA3 300 ppm) were the three treatments in this completely randomised design trial with four replications. Time to germination, plant height, fresh weight, and dry weight of alfalfa feed were some of the noted factors. The findings showed that out of the three treatments, P0 (21.25 hours), P2 (20.30 hours), and P1 (19.45 hours) had the quickest germination times.The highest plant height was recorded in P2 (4.24±1.99 cm), followed by P1 (3.79±1.83 cm) and P0 (3.09±1.90 cm). The highest fresh weight was also observed in P2 (24.75±1.89 g), while the highest dry weight was found in P0 (10.00±0.85%). Statistical analysis indicated that GA3 application had a significant effect on germination time but did not significantly affect plant height, fresh weight, and dry weight. It can be concluded that GA3 application effectively accelerates the germination of alfalfa; however, it does not significantly improve biomass production of alfalfa fodder.
