Abstract

Edamame (Glycine max (L.) Merril) is a legume commodity with high economic potential, and its production demand continues to increase in both domestic and export markets. However, edamame productivity is often constrained by pest attacks (OPT) such as Spodoptera litura, Etiella zinckenella, Riptortus linearis, and other major pests. In this study, the presence of spider predators in edamame plants was examined in relation to different concentrations of a botanical pesticide derived from paitan leaves (Tithonia diversifolia). Using a Randomized Block Design (RBD) with six treatments (P0, control), P1, P2, P3, P4, and P5, each with four replications, the study was place in Sembalun Village, East Lombok Regency, from May to July 2024. Three indices—the dominance index, the abundance index, and the Shannon-Wiener diversity index (H')—were used to evaluate the data. The results showed 6 spider genera from 5 families, with Pardosa and Pirata being the most dominant. The highest population was found in the control (P0) and decreased with increasing pesticide concentration. The highest diversity index was at P0 (H’=1.382) and the lowest at P5 (H’=1.222), with the evenness index categorized as moderate and the highest dominance index at P2 (0.372). In conclusion, higher concentrations of paitan leaf extract reduced the presence of spider predators, indicating that its application should consider appropriate doses to avoid harming natural enemies.

Abstract

Coastal waters are vital for aquatic life and human activities, yet their quality is highly susceptible to environmental pressures. Because macrozoobenthos are sensitive to environmental changes and have limited mobility, they are frequently utilized as bioindicators. This study aims to examine the structure of the macrozoobenthos community in the waters of Sungai Kakap Village, Kubu Raya Regency, and its relationship with environmental parameters. Samples were collected at five stations using purposive sampling with line transects and quadrants, then analyzed for density, diversity (H'), evenness (E), and dominance (C). A total of 14 species were found with distinct dominant patterns across stations, notably the high dominance of Neritina violacea, Corbicula fluminea, and Corbicula fluvitalis at Stations I, III, and V, respectively. Community structure analysis showed low diversity (H': 0.33–0.65) and high dominance (C: up to 0.84), suggesting a community structure dominated by a few species, leading to relatively low stability. Environmental parameters—temperature (30.1–31.7∘ C), salinity (0.50–3.00%), pH (5.45–7.58), and DO (3.77–7.51 mg/L)—were found to influence species distribution. These results confirm that macrozoobenthos is an effective bioindicator for water quality assessment in the Sungai Kakap area. The low community stability implies a need for consistent monitoring to prevent further degradation. Future research should focus on the impact of specific pollutants on these dominant species to support informed mangrove ecosystem management.

Abstract

The chlorophyll content in coffee leaves greatly influences growth productivity and productivity. This study aimed to examine the effect of seed soaking and rhizosphere bacteria microcapsule dosage on the growth rate and chlorophyll content of Liberica coffee leaves planted on peatland. The experiment used a completely randomized design (CRD) with two factors, namely seed soaking time (0, 9, 10, and 11 hours) and rhizosphere bacteria microcapsule dosage (0, 10, 15, and 20 grams), with a total of 16 treatment combinations replicated twice. The parameters measured included leaf area, number of leaves, and chlorophyll content. The results showed that 11-hour seed soaking treatment produced the largest leaf area (40.32 mm), 9–10 hours soaking gave the highest number of leaves (10.34), and 20 grams of microcapsules gave the highest chlorophyll content (79.16 CCI). ANOVA and Duncan's test showed that seed soaking and microcapsules significantly affected the growth and chlorophyll content of leaves. In conclusion, the combination of seed soaking for 9–11 hours and a 20 gram microcapsule dose can improve the growth and quality of Liberica coffee leaves.

Abstract

Soil-transmitted helminths (STH) remain highly prevalent in Indonesia and continue to pose a major public health concern, particularly in areas with limited diagnostic capacity. Reliable and cost-effective detection methods are crucial for accurate surveillance and the success of national deworming programs. This study aims to compare three commonly used microscopic techniques (wet mount, Kato-Katz, and sedimentation) to evaluate their diagnostic performance and suitability for use in resource-limited settings through a literature review. Wet mount is rapid and inexpensive but limited by low sensitivity in light infections. The Kato-Katz method, endorsed by the World Health Organization as the gold standard, offers higher sensitivity and enables egg quantification, though its performance decreases when only a single sample is examined. Sedimentation is useful for detecting heavier trematode eggs and is relatively simple to perform, but sensitivity remains a challenge. Overall, while all three techniques are feasible in resource-limited settings, their effectiveness depends on infection intensity, sample handling, and examiner skill. Training and quality control are therefore essential to improve diagnostic accuracy and support ongoing STH control programs in Indonesia.

Abstract

A condition known as stunting happens when linear development falls short of its full potential, especially if it happens within the first 1000 days of life. Stunting prevalence in Indonesia was 21.5% in 2023, with a rate of 17.5% in Lombok Tengah District, West Nusa Tenggara Province. This study explores the relationship between WASH-related risk factors and stunting among children 6-24 months in Puyung Health Center area, Lombok Tengah District. This study is an observasional analytical research with a cross-sectional design. The research subjects included of 90 mothers or caregivers of children aged 6-24 month in Puyung Health Center are, Lombok Tengah Disctrict. Sampling was conducted through stratified random sampling. Data were collected using the KIA and a modified SSGI questionnaire 2022. The chi-square test was used for a bivariate data analysis. According to the statistical analysis of 90 respondents, 46 respondents (51.1%) were categorized as having no WASH-related hazards, while 49 infants (54.5%) suffered from stunting. A p-value of 0.821 (p>0.05) was achieved following a bivariate analysis using the chi-square test. These findings suggest that the prevalence of stunting in babies aged 6 to 24 months and in the Puyung Health Center region of the Central Lombok District do not significantly correlate with WASH risk factors. In the Puyung Health Center region of the Central Lombok District, there is no discernible link between stunting and WASH risk factors in children aged 6 to 24 months.

Abstract

Land kale (Ipomea reptans P.) is a popular leafy vegetable in Indonesia due to its fast growth and high nutritional value. Its productivity relies heavily on the proper application of fertilizer. This study investigates the effects of NPK fertilizer, Bokashi fertilizer, and their combination on land kale's vegetative growth and chlorophyll content. Conducted from May to July 2025 at the Faculty of Agriculture, University of Mataram's greenhouse, the experiment employed a Completely Randomized Design (CRD) with two factors: five levels of NPK fertilizer (0–2 gr/100 ml water) and five levels of Bokashi fertilizer (0–400 gr/polybag). Growth parameters measured included plant height, number of leaves, stem diameter, fresh weight, dry weight, and chlorophyll content. Data analysis involved two-way ANOVA and Duncan’s Multiple Range Test (DMRT). Results indicated NPK fertilizer significantly affected all growth parameters and chlorophyll content, while Bokashi fertilizer significantly influenced stem diameter, fresh weight, and dry weight, but not plant height, leaf number, and chlorophyll content. The interaction between NPK and Bokashi fertilizers significantly impacted plant height, fresh weight, and dry weight, though it had no significant effect on leaf number, stem diameter, and chlorophyll content.

Abstract

Bioremediation is a sustainable approach to environmental restoration; however, its effectiveness is often constrained by limited understanding of molecular mechanisms and complex microbial interactions. This study aims to systematically review the transformative role of integrated multi-omics approaches including genomics, transcriptomics, proteomics, and metabolomics in enhancing bioremediation efficiency. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across 10 empirical studies published between 2019 and 2024. Data were collected from Scopus, Web of Science, and PubMed databases using the keywords “bioremediation,” “multi-omics,” “microbial interactions,” and “environmental restoration.” Data analysis employed a qualitative thematic synthesis approach to identify key patterns and contributions. The findings reveal that multi-omics integration enables the elucidation of key catabolic pathways, identification of critical degradative enzymes, and characterization of synergistic microbial dynamics that drive pollutant degradation. Furthermore, integrating multi-omics data facilitates the rational design and engineering of synthetic microbial consortia with significantly improved bioremediation performance. In conclusion, the multi-omics framework represents a paradigm shift from descriptive to predictive and engineering-based bioremediation, providing a strong scientific foundation for more precise and sustainable environmental recovery strategies.

Abstract

The availability of vital macronutrients from NPK fertilizer and the enhancement of soil fertility with bokashi organic fertilizer have a significant impact on the vegetative growth of green eggplant (Solanum melongena L.). This study aims to determine the effect of NPK, bokashi, and a combination of both on the chlorophyll content and vegetative growth of green eggplant. NPK fertilizer dosage (0 g, 1 g, 1.5 g, and 2 g) and bokashi fertilizer dosage (0 g, 100 g, 200 g, 300 g, and 400 g) were the two components in this study, which employed a completely randomized design (CRD) with three replicates. Plant height, leaf count, leaf area, fresh weight, dry weight, and chlorophyll content were among the metrics measured. ANOVA at the 5% level and DMRT were used to analyze the data. The findings demonstrated that the chlorophyll content and other vegetative growth indices were significantly impacted by NPK fertilizer. Chlorophyll content was not considerably impacted by the bokashi fertilizer application, however all vegetative growth indices were significantly impacted. With the exception of leaf area, the combination of NPK and bokashi fertilizers did not substantially affect most measures. The combination of 400 g bokashi and 2 g NPK yielded the highest vegetative growth indices and was the best treatment. Meanwhile, the combination of NPK 2 g and bokashi 300 g produced the maximum chlorophyll content. Through the use of integrated organic and inorganic fertilization, this study demonstrates how adding bokashi to NPK fertilizer can boost plant growth and nutrient use efficiency, helping to create sustainable farming methods.

Abstract

Differences in meat tenderness between male and female animals are influenced by physiological and hormonal factors that affect muscle composition and connective tissue development. Understanding the effect of sex on meat tenderness is important for improving the quality of local goat breeds such as the Kacang goat, which is commonly raised under traditional semi-intensive systems. This study analyzed and compared the tenderness profile of meat from one-year-old male and female Kacang goats reared semi-intensively. Meat samples from the loin and shank of three male and three female goats were collected and tested using the Warner–Bratzler Shear Force (WBSF) method, and data were analyzed using an independent t-test to determine differences in tenderness between muscle types and sexes. The results showed a significant difference in male goats, with shank meat being tougher than loin meat, while in female goats, tenderness between both cuts was relatively uniform. These variations are attributed to physiological and hormonal differences, particularly higher testosterone levels in males that increase connective tissue density in more active muscles. In conclusion, sex significantly influences the tenderness of Kacang goat meat, with females producing meat of more consistent tenderness across different cuts, whereas males exhibit greater variation. The findings contribute to a better understanding of sex-related factors affecting meat quality and provide a scientific basis for improving goat meat production and management practices.

Abstract

A lung abscess is the formation of a thick-walled cavity filled with purulent material due to suppuration and necrosis of the lung parenchyma. Cases of lung abscess are relatively rare today and were most common in the pre-prebiotic era due to the lack of treatment for bacterial infections. This literature review aims to obtain information related to lung abscess its etiology, diagnostics, and treatment options. The article was compiled using a literature search through databases such as PubMed, ScienceDirect, and Google Scholar using the keyword "lung abscess." The findings indicate that lung abscess is a condition characterized by the formation of a pus-filled cavity resulting from suppuration and necrosis of lung tissue. This disease is commonly caused by anaerobic bacterial infection, although aerobic bacteria may also play a role. Despite its relatively low incidence today, lung abscess remains an important clinical problem as it can arise as a complication of pneumonia or tuberculosis. Diagnosis is established through medical history, physical examination, and supporting investigations such as radiology and sputum culture. Management includes long-term antibiotic therapy, drainage, and surgical intervention for refractory cases. Preventive efforts involve maintaining oral hygiene, reducing alcohol consumption, and avoiding aspiration risk factors. Therefore, comprehensive understanding of the definition, pathogenesis, clinical features, diagnosis, and management of lung abscess is essential to support clinical practice in pulmonary medicine.
