Abstract

BBTV (Banana Bunchy Top Virus) is a viral disease that attacks cultivated banana plants and can cause stunting. The symptoms of BBTV disease attack on banana plants are narrowed, piled up leaves and stunted plants. The disease is caused by an insect vector. Pentalonia nigronervosa is the vector insect that transmits BBTV disease. The purpose of the research was to see the java turmeric plant as an alternative host for population growth and BBTV disease vector. The method in the study used a Randomized Group Design. This treatment consists of two treatments with 10 replications. Based on the results of research conducted on the population of P. nigronervosa experienced fluctuations, but high growth in water media. BBTV disease that attacks banana plants in each treatment has the highest incidence in the control treatment, namely, 73.33% dan the lowest disease incidence the turmeric treatment was 6.67%. The highest intensity of BBTV disease attack in the control treatment was 42.06%, while the lowest in the Javanese turmeric treatment was 1.50%. P. nigronervosa inoculated on Javanese turmeric for 72 days can suppress BBTV disease transmission. However, based on the analysis of each treatment, no significant differences were found. P. nigronervosa has the highest population in the soil medium 95.4 individuals and water medium 86.7 individuals. The population of P. nigronervosa has a good development in turmeric plants.

Abstract

Anemia is a common health problem worldwide, especially in developing countries. Oil palm plantation workers are at high risk of developing anemia due to various factors such as diet, working conditions, and pesticide exposure. This study analyzes the risk factors associated with anemia in oil palm plantation workers in Ogan Komering Ilir Regency. The research method used was an analytical survey with a cross-sectional approach. Data were collected through structured interviews and questionnaires with 33 oil palm plantation workers. The variables studied included age, occupation, level of knowledge, family support, and specific exposure. Statistical analysis was performed using the chi-square test. The results showed that the incidence of anemia in plantation workers reached 14.7%. Occupational factors (p = 0.011) and family support (p = 0.005) had a significant relationship with the incidence of anemia. However, no significant relationship was found between age (p = 0.414), level of knowledge (p = 1.000), and exposure (p = 0.634) with the incidence of anemia. This study concludes that occupational factors and family support contribute to the incidence of anemia in oil palm plantation workers. Further research is needed to explore other risk factors that may influence the incidence of anemia in this group.

Abstract

Acid mine drainage (AMD), characterized by high acidity and elevated concentrations of heavy metals, poses a significant threat to aquatic ecosystems. This study aims (1) to analyze and optimize the effects of fly ash (FA) and bottom ash (BA) on the reduction of pH, Fe, Mn, and total suspended solids (TSS) through adsorption processes, and (2) to evaluate the impact of varying adsorbent mass ratios in determining optimal treatment efficiency. Adsorption experiments were conducted using 10, 20, and 30 g of FA, BA, and their combinations, with surface morphology characterized via scanning electron microscopy (SEM). The results demonstrated that 30 g of BA achieved the highest removal efficiency, increasing pH from 2.8 to 7.5, reducing Fe from 12.2 mg/L to 1.6 mg/L, Mn from 7.9 mg/L to 0.9 mg/L, and TSS from 40 mg/L to 5 mg/L. SEM analysis revealed that BA possesses a higher pore density and carbon content than FA, offering a greater number of active sites for adsorption. The t-test indicated that the individual and combined effects of FA (X1), BA (X2), and their mixture (X3) significantly influenced treatment performance. An adjusted R² value of 83.9% confirmed a strong correlation between adsorbent variables and improvements in AMD quality.

Abstract

The use of forensic biology methods plays an important role in handling criminal cases such as sexual violence, murder, and assault to enhance the quality of criminal investigation. These methods use polymorphic genetic markers such as short tandem repeat (STR) or microsatellites to identify individuals based on the DNA profile of the cell nucleus left on the evidence. STR markers are considered suitable for forensic analysis due to their ability to work with degraded DNA and the high heterozygosity, providing strong discrimination capabilities. The DNA profiling process involves collecting evidence samples, DNA extraction, PCR amplification, capillary electrophoresis, and comparison with national or international DNA databases. All processes follow standards to ensure accurate results. Challenges in STR analysis include the need for skilled analysts, protocol updates, database expansion, and ethical considerations regarding genetic data. Improvements in the forensic system will enhance law enforcement effectiveness and strengthen public trust in the future of forensic science.

Abstract

Eurycoma longifolia, commonly known as Tongkat Ali or Pasak Bumi, is a traditional medicinal plant widely used in Southeast Asia, including Sumatra, Indonesia. It is traditionally recognized for its aphrodisiac and general health-promoting properties. However, recent phytochemical and pharmacological studies have identified a diverse range of secondary metabolites in this plant, such as quassinoids, alkaloids, triterpenes, and squalene derivatives, that exhibit promising anticancer activities. This review aims to comprehensively explore the diversity of secondary metabolites found in E. longifolia populations in Sumatra and assess their potential as anticancer agents by analyzing local bioresources. A systematic literature review was conducted by collecting data from scientific databases including PubMed, ScienceDirect, and Google Scholar using targeted keywords. Selection criteria focused on studies discussing secondary metabolite content, anticancer mechanisms, toxicological data, and drug development potential. The findings show that several compounds in E. longifolia can inhibit cancer cell proliferation, induce apoptosis, and prevent angiogenesis and metastasis in vitro and in vivo. Despite challenges such as low bioavailability and lack of clinical trials, the plant’s abundant presence in Sumatra and the bioactivity of its metabolites make it a promising candidate for the development of novel, plant-based anticancer therapies. Further research and standardization are recommended to optimize its pharmaceutical application.

Abstract

Oxidative stress is a condition characterized by an imbalance between the production of free radicals and the body's ability to neutralize them with antioxidants. In young adults, oxidative stress is a significant risk factor for chronic diseases such as diabetes, hypertension, and heart disease. This study aims to analyze the effect of physical activity on oxidative stress biomarkers, specifically malondialdehyde (MDA) and glutathione peroxidase (GPX), in young adults. A cross-sectional study was conducted involving 50 participants aged 20–30 years, categorized into low, moderate, and high physical activity groups. Physical activity levels were assessed using a questionnaire, while MDA and GPX levels were measured through blood sample analysis using the spectrophotometric method. The data were analyzed using correlation and ANOVA tests to evaluate the relationships and differences in biomarker levels among the physical activity groups. The results showed significant differences in oxidative stress biomarkers and antioxidant capacity between physical activity groups (p < 0.05). Higher physical activity levels were associated with lower MDA levels, indicating reduced lipid peroxidation and oxidative stress. These findings support the promotion of regular, moderate-to-vigorous physical activity among young adults as an effective strategy for enhancing antioxidant defense, reducing oxidative stress, and potentially preventing chronic diseases linked to oxidative damage.
