Published: February 2025

Using organic fertilizer can increase soil fertility, which is crucial for plant growth. Another organic material source that may be utilized as fertilizer is water hyacinth (Eichhornia crassipes). The chemical makeup of water hyacinth was examined in this study, and the results indicated that its organic matter content was 78.47%, its organic carbon content was 21.23%, its total nitrogen content was 0.28%, its total phosphorus content was 0.0011%, and its total potassium content was 0.016%. It has been demonstrated that applying water hyacinth-based liquid organic fertilizer to corn (Zea mays) plants actually affects crop output. Utilizing water hyacinth not only improves soil fertility but also lessens pollutants in the environment caused by overgrowth in waterways. Water hyacinth can therefore be utilized as a sustainable and eco-friendly organic fertilizer option.

Spinach (Amaranthus spp.) is a vegetable plant that is highly dependent on the availability of light and nutrients for its growth. Proper spacing plays an important role in influencing a plant's access to light and nutrients, which ultimately impacts its yield. This study examines the impact of planting distance on light and nutrient competition in spinach. Planting spacing that is too tight can lead to intense competition between plants, reduce the efficiency of photosynthesis, and increase the risk of etiolation in lower plants. On the contrary, planting spacing that is too wide reduces land use efficiency and increases the likelihood of weed growth. The ideal planting distance ranges from 15-20 cm between plants, which ensures maximum utilization of light and nutrients without resulting in excessive competition, thus supporting optimal growth and yield

Organic farming is increasingly being looked at as a solution to improve soil quality and produce sustainable agriculture. This study aims to explore the impact of organic farming on soil quality and yields of wet-rice farming in Nias Islands. Based on existing research, organic farming systems are proven to provide great benefits to soil fertility, including by increasing organic matter content, boosting soil microbial activity, and improving soil structure. The use of techniques such as crop rotation, organic fertilizers and mulching have been shown to improve soil quality, increase its ability to store water and reduce erosion. In addition, more diverse and active soil microbes also contribute to more efficient nutrient cycling, reducing dependence on synthetic fertilizers and helping to control pests naturally. While the initial adoption of organic farming may result in lower yields, research shows that in the long run, yields increase as soil quality improves. Organic farming also offers better resilience to climate change, especially in terms of the soil's ability to retain water and reduce the impact of drought. Thus, organic farming in Nias Islands can not only increase agricultural productivity, but also support environmental sustainability. Therefore, the application of organic farming is the right choice to improve food security and preserve nature in Nias Islands

Authors: Kawashima Toshiyuki , Bohoun Christian A , Uda Takehiro
Published: February 2025

Introduction: Subdural hematomas (SDHs), particularly prevalent in older populations, present significant clinical challenges. For its treatment, middle meningeal artery embolization (MMAE) has gained attention as a potential adjunctive therapy to surgical intervention. This systematic review and meta-analysis evaluated the effectiveness and safety of combining MMAE with surgery compared to surgery alone.
Methods: A systematic review and meta-analysis were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant studies were identified through comprehensive database searches. Inclusion criteria focused on randomized controlled trials comparing adjunctive MMAE with surgery to surgery alone for SDH. Data on recurrence rates, functional outcomes, mortality, and adverse events were extracted and synthesized.
Results: Six randomized control trials, involving 1,327 patients, met the inclusion criteria. In cases of chronic SDH, adjunctive MMAE significantly reduced recurrence rates compared to surgery alone, with an odds ratio (OR) of 0.45 (95% CI: 0.22–0.93; p = 0.03; I² = 0%). However, no improvement in functional outcomes was observed (OR: 1.15; 95% CI: 0.43–3.02; p = 0.78; I² = 0%). For subacute or mixed subacute and chronic SDH, limited evidence showed no significant reduction in recurrence rates (OR: 0.56; 95% CI: 0.21–1.49; p = 0.25; I² = 70%) or functional improvement (OR: 0.77; 95% CI: 0.40–1.49; p = 0.44). Adjunctive MMAE was not associated with a significant increase in mortality (OR: 0.72; 95% CI: 0.55–0.95; p = 0.02) or adverse events (OR: 0.89; 95% CI: 0.61–1.31; p = 0.55).
Conclusion: Adjunctive MMAE significantly reduces recurrence rates in chronic SDH but does not provide additional functional benefits. Its efficacy in subacute SDH remains inconclusive, highlighting the need for further research.

Authors: Ade Damaria Mukti  , Rani Yosilia  , Eka Septiawati
Published: February 2025

Adsorption involves the attachment of molecules or ions onto the surface of an adsorbent. Activated charcoal is effective in adsorbing organic substances, odors, colors, and various pollutants from water. In this process, toxic particles adhere to the charcoal, reducing pollutant concentrations and improving water quality. This study examines the effectiveness of coconut shell activated charcoal in adsorbing laundry wastewater, specifically focusing on reducing BOD, COD, and coliform levels. A quantitative approach using a completely randomized design (CRD) was employed, with varying charcoal weights (1 g, 2 g, and 3 g) to assess its impact on water quality. Each treatment used 100 ml of laundry wastewater. The results showed that activated charcoal from coconut shells was effective in reducing BOD and COD levels, but not in lowering coliform concentrations. The third treatment (3 g) yielded the most significant BOD reduction, with a final concentration of 20 mg/L and an effectiveness of 96.66%. For COD, the third treatment resulted in a concentration of 71 mg/L and an effectiveness of 93.07%. However, coliform levels remained unchanged in all treatments, exceeding 160,000/100 mL, far above the standard maximum of 3000/100 mL, with 0% effectiveness in reducing coliform.

Stomatal Density of Jackfruit (Artocarpus heterophyllus Lamk.) Leaves as a Bioindicator of Urban Air Quality in Bandar Lampung
Authors: Rahmawati Ayu , Nahari Fadhilah Savana Nurun , Winandari Ovi Prasetya
Published: February 2025

Urban air pollution is a growing environmental concern, particularly in rapidly developing cities where vehicular emissions contribute significantly to deteriorating air quality. This study investigates the correlation between stomatal density in jackfruit (Artocarpus heterophyllus Lamk.) leaves and air quality in Bandar Lampung, focusing on two high-traffic urban locations: Sultan Agung Street and Pangeran Emir M Noer Street. Using a quantitative approach, leaf samples were collected through purposive sampling and analyzed for stomatal density using light microscopy (400× magnification). Concurrently, air quality was measured by assessing carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM10 and PM2.5) concentrations, which were compared against National Ambient Air Quality Standards (PP No. 41 of 1999). The results indicate a positive correlation between traffic intensity and stomatal density, suggesting that jackfruit trees increase stomatal density as an adaptive response to vehicular pollution. However, while enhanced stomatal density may improve CO₂ uptake for photosynthesis, excessive stomatal opening could lead to higher pollutant absorption, necessitating stomatal closure mechanisms during peak pollution periods. The findings confirm that jackfruit trees can serve as effective bioindicators for urban air pollution monitoring, given their physiological adaptability and widespread distribution in tropical urban settings. This research underscores the potential of plant-based bioindicators in sustainable air quality assessment and urban environmental management strategies.

Authors: Bianchi Sebastián E. , Benito Gustavo A. , Isla Facundo
Published: February 2025

Durante décadas, la teoría de falla de Griffith fue el marco teórico más adecuado para explicar el comportamiento de un material frágil o cuasi-frágil en fractura. Con el avance de la computación y la modelación numérica, este enfoque comenzó a presentar debilidades, sobre todo desde el punto de vista práctico, que fue necesario salvar. Así es como aparecieron mejoras y nuevos modelos, como el de zona cohesiva, que dieron lugar a mejores resultados, a una mayor facilidad para su implementación computacional, así como a una forma más adecuada de representar el comportamiento de una interfaz entre dos materiales. Sin embargo, aún hay aspectos no comprendidos completamente de este comportamiento, y el aporte de nuevos resultados experimentales y numéricos es de gran relevancia. En ese sentido, este trabajo consiste en evaluar el comportamiento de la interfaz entre hormigón reforzado con fibras y concreto asfaltico por medio de la simulación de ensayos de vigas, utilizando el marco teórico del modelo de zona cohesiva, teniendo en cuenta una ley tracción-separación lineal y otra exponencial, e implementado por medio de elementos finitos de interfaz derivados de un funcional Lagrangiano aumentado. Los resultados son contrastados con resultados numéricos y experimentales obtenidos por otros autores para ser validados.

The purpose of this study was to establish the effect of service quality on TB patient‟s satisfaction in public and private health facilities of Kampala Specifically, the study set out to establish the level of TB treatment adherence in public and private health facilities in Kampala and the effect of tangibility, responsiveness and empathy on TB patient satisfaction in public and private health facilities in Kampala. The study used a cross-sectional study using a quantitative approach. The study population included 18 private and 11 public health facilities in Kampala Capital district with an estimated population of 2000 patients in one quarter from which a sample of 278 TB patients were accessed. Data was collected using a questionnaire and was analyzed using SPSS and descriptive, correlation and regression analyses. The study found a high level of adherence where TB patients always took a full prescribed daily dose. Some (10%) TB patients did not pick, fulfill appointment or take drug regimens on time. The study also found that tangibility was the second most significant predictor of the variance in patient satisfaction while responsiveness was the most significant predictor of the variance in patient satisfaction. In this study Empathy did not have any significant effect on patient satisfaction. To enhance patient satisfaction with TB services, the study recommends that the management supports TB units by procuring modern TB diagnostic and Treatment monitoring equipment and also develop a national policy of capacity building through training of doctors, Clinicians, Nurses and Counselors. The management of all health facilities should training staff in TB clinics in customer service and care to equip them with necessary knowledge, skills and attitudes for enhanced responsiveness

Background: Central corneal thickness (CCT) is a crucial parameter in ophthalmology, influencing the diagnosis and management of various corneal and glaucomatous conditions. Accurate CCT assessment is essential for clinical decision-making, surgical planning, and disease monitoring. Multiple imaging modalities, including anterior segment optical coherence tomography (AS-OCT), corneal topography (CT), and specular microscopy (SM), are commonly used for CCT measurement. However, variations in measurement accuracy and agreement among these techniques necessitate comparative evaluation to determine their clinical interchangeability.
Objective: To determine the agreement of CCT measurements obtained using AS-OCT, CT, and SM in healthy individuals and assess the correlation between these modalities.
Methods: This prospective, cross-sectional study was conducted at the Armed Forces Institute of Ophthalmology from September 2023 to February 2024. A total of 125 right eyes of healthy volunteers aged 18–50 years with normal corneas (spherical equivalent: -2.00 D to +2.00 D, intraocular pressure <21 mmHg) were included. CCT was measured using Shin-Nippon SPM-700 (SM), TMS-5 Tomey (CT), and TOPCON 3D OCT-2000 (AS-OCT). Each measurement was performed three times by a single examiner, with a five-minute interval between devices. Pearson's correlation coefficient (r) was used to assess agreement among the techniques, with p ≤ 0.001 considered statistically significant.
Results: The mean age of participants was 35.33±8.32 years (range: 21–50 years), with 55.2% males and 44.8% females. The mean CCT values obtained were 505.74±11.36 μm (SM), 528.79±13.12 μm (CT), and 518.46±19.54 μm (AS-OCT). A strong correlation was observed between CT and AS-OCT (r = 0.51, p ≤ 0.001), followed by a moderate correlation between SM and AS-OCT (r = 0.39, p ≤ 0.001) and a weaker but significant correlation between SM and CT (r = 0.36, p ≤ 0.001).
Conclusion: CCT measurements obtained using AS-OCT, CT, and SM demonstrated reasonably consistent results, with AS-OCT and CT exhibiting the highest agreement. However, variations in correlation strength suggest that these modalities may not be directly interchangeable without adjustment. These findings emphasize the need for careful selection of measurement techniques based on clinical requirements.
