Abstract

Activated carbon from corn stalks (Zea mays L.) has been successfully synthesized by the dehydration method and used as a supercapacitor electrode. Corn stalk powder was dehydrated with 1 MH2SO4 and activated with 5 M NaOH at a carbon and activator mass ratio of 1:4 with a heating temperature of 800°C and an N2 gas heating rate of 10°C/minute for 1 hour. SEM characterization results show that heterogeneous pores have formed on the surface of corn stalk-activated carbon. EDX results showed a carbon percentage of 54.82%; this data is supported by FTIR results, which show several functional groups containing C and O atoms on the surface of activated carbon. Based on desorption adsorption isotherm analysis, the activated carbon shows H4 type with a specific surface area of 117.973m2/g, average pore diameter of 1.730 nm and total pore volume of 0.1021 cm3/g. Measurement of the electrochemical properties of corn stalk activated carbon with a three-electrode system and 3 M KOH electrolyte showed a specific capacitance value of 133.9 F/g, power density 225.2 W/kg and energy density 0.863 Wh/kg. The synthesis of activated carbon through the dehydration method offers advantages in terms of simplicity in preparation, low cost, shorter synthesis time and being environmentally friendly.

Abstract

This study aims to find the presence of microplastics in Shellfish through the literature review method of several studies conducted. The increase in plastic pollution in water systems since the 1950s has become a significant problem worldwide due to the slow decomposition rate. Microplastics, mainly primary and secondary, can accumulate in marine organisms such as Shellfish and enter the food chain, which is a concern for humans. Shellfish, especially M. galloprovincialis, can be used as bioindicators and bioremediation tools to tackle microplastic pollution. Microplastics are a severe problem in the world's oceans, especially in marginal and densely populated coastal areas. Marine organisms like Shellfish contain microplastics, which can cause physical damage and disrupt the immune system. Mytilus edulis clams and Crassostrea gigas oysters are the most consumed species with significant microplastic content. Research has also shown the presence of microplastics in Mytilus chilensis in the Gulf of Ushuaia, South America, with fibers and fragments being the most common types. Microplastics are also found in wild mussels in Tunisia, with the estimated annual dietary intake of microplastics by Tunisians through wild mussel consumption amounting to 4.2 particles per capita per year. Mussels of the genus Mytilus were proposed as guardian organisms to monitor microplastic pollution.

Abstract

Heavy-metal contamination remains a critical ecological threat in tropical coastal ecosystems, particularly along the West Coast of Sumatra, where concentrations of Pb, Cd, and Cu frequently approach or exceed biological stress thresholds. This article evaluates marine microalgae as indicators of heavy metal pollution, combining global biomarker evidence with region-specific hydrodynamic conditions, referring referring to publications from the last six years. The findings reveal strong cross-study convergence in microalgal responses, including chlorophyll degradation, photosynthetic inhibition, oxidative stress, and antioxidant enzyme activation. These biomarker patterns align closely with local observations from Sumatra, indicating that microalgae operate within exposure ranges known to induce sublethal physiological impairment. Hydrodynamic modulation driven by monsoon cycles further amplifies metal bioavailability, producing alternating acute and chronic stress regimes that chemical monitoring alone often fails to detect. This review provides the first integrated assessment linking microalgal biomarker evidence with monsoon-regulated metal dynamics in Indonesian coastal waters. By synthesizing mechanistic, ecological, and environmental data, the study establishes a robust scientific foundation for adopting microalgae as a core component of early-warning systems and coastal biomonitoring frameworks. The findings also highlight methodological gaps and propose future directions to strengthen monitoring programs within a One Health perspective

Abstract

Tuberculosis (TB) is a global health problem requiring patient adherence to treatment. This study aimed to evaluate the effect of pharmacist-led medication counseling on tuberculosis medication adherence in patients at Puskesmas Rasimah Ahmad and Puskesmas Mandiangin, Bukittinggi City. The research employed a quasi-experimental design with a pretest-posttest one-group approach. The sample comprised 24 TB patients selected through total sampling. Data were collected using the Morisky Medication Adherence Scale-8 (MMAS-8) questionnaire before and after the counseling intervention. Data analysis included univariate and bivariate analyses using Kendall's tau-b, Wilcoxon signed-rank test, and Mann-Whitney U test. The findings indicated no association between age and TB treatment adherence before and after counseling. However, there was an association between gender, education, and occupation with TB treatment adherence after counseling. Treatment duration also showed a significant influence on patient adherence. Patient adherence levels increased significantly after counseling in both health centers (Puskesmas Rasimah Ahmad: p=0.024; Puskesmas Mandiangin: p=0.034). No significant difference in adherence levels was found between the two health centers post-counseling (p=0.320). This study concludes that pharmacist-led medication counseling effectively improves TB patient adherence. Healthcare professionals, particularly pharmacists, are encouraged to provide interactive and repetitive counseling to TB patients to support treatment success.
