Abstract

The Super Water Absorbent (SWA) polymer is a type of polymer that has exceptional water absorption capabilities while remaining insoluble in water. In this study, the authors conducted research on the modification of SWA by including acrylic acid and acrylamide monomers, followed by a crosslinking process utilising gamma irradiation. This study investigated the impact of acrylic acid and gamma irradiation on the mechanical characteristics of SWA. The experimental findings demonstrated a notable enhancement in the mechanical properties of the hydrogel by the incorporation of acrylic acid. This was evidenced by a substantial rise in the hardness value, which rose from 11.09 mJ to 36.13 mJ.

Abstract

The lithium ion battery is a type of secondary battery. A good component to be used as the anode of a lithium ion battery is Li4Ti5O12 (LTO). LTO has a low conductivity value so doping is necessary. Doping particle size greatly affects the conductivity of LTO. The purpose of this doping was carried out to find out how the effect of CaO nanoparticle doping on the conductivity value of the LTO battery anode using the coprecipitation method by varying the molarity of NaOH, namely 1M, 3M and 7M. Based on the results of research on the influence of NaOH molarity, it produces different sizes of nanoparticles. The smallest nanoparticle size was obtained in the 3M sample variation, which was 175.0 nm. With a purity of CaO nanoparticles of 96.35%. While the conductivity value of the lithium ion battery doped with CaO nanoparticles with three variations of NaOH molarity, the optimum value was obtained in the 1M sample, which was 1.06 × 10-6 S/cm. This is because the 1M variation produces very low impurities compared to the 3M and 7M variations which have more impurities, this can affect the conductivity value.

Abstract

The household-scale microgreen urban farming program was implemented in Lubuk Kelik Village, Bangka Regency, as a community empowerment initiative to improve family income and prevent stunting. This program was designed to utilize limited household land through the cultivation of microgreens, which are easy to grow, have a short harvesting period, and provide high nutritional value. The implementation methods included socialization, technical training, cultivation practices, mentoring, and evaluation of outcomes. The results showed an increase in participants’ knowledge and skills in managing microgreens independently. Some participants consumed the harvest to improve family nutrition, while others began marketing the products within their neighborhood, contributing to additional household income. This program has proven to support the availability of affordable nutritious vegetables while also strengthening community awareness of stunting prevention. Therefore, microgreen urban farming has the potential to become an applicable and sustainable model for community empowerment.

Abstract

Background: Due to its adverse outcomes and thromboembolic complications, early detection of atrial fibrillation (AF) is advisable in the general population. This study aims to compare the diagnostic ability of two distinct method in smartphone application format, namely : AliveCor KardiaMobile and FibriCheck. Methods: This study was conducted in Mohammad Hospital General Hospital Palembang with convenience sampling of 170 participants aged 18 years or older. The subjects underwent Fibricheck and KardiaMobile recordings followed by 12 lead electrocardiogram read by board-certified cardiologist as the diagnostic standard. Results: After the exclusion of previous pacemaker implantation (n=7), 163 patients were included in the study. The mean age was 51±15 years with gender distribution of 74.8% men and 25.2% women. Most of the subjects were asymptomatic (87.1%) with mean blood pressure of 130/80 mmHg. The Fibricheck readings showed sensitivity of 73% and specificity of 93%, meanwhile Kardiamobile was able to detect AF with sensitivity of 77% and specificity of 98%. Conclusion: In our study, KardiaMobile demonstrated overall greater sensitivity and specificity when compared to FibriCheck. However, KardiaMobile requires an external metal sensor that must be puchased separately. To the best of our knowledge, this is the first study to directly compare both methods in the Indonesian population.

Abstract

Cassava pulp or bagasse is a by-product of cassava processing with high starch and cellulose, showing strong potential for development into various high-value products, including hydrogel. Hydrogel is a polymer capable of absorbing a large amount of water without dissolving and is suitable for several applications. Therefore, this study aimed to synthesize and characterize hydrogel made from cassava waste pulp with different concentrations of acrylamide and acrylic acid (AA). The treatments used were the percentage of acrylic acid, namely 0, 5, 15, 25, and 35%, alongside N, N-methylene bisacrylamide (MBA) percentages (0, 0.5, 1, and 1.5%). Parameters observed were swelling, swelling kinetics, gel fraction, mechanical properties, and surface morphology. The results showed that the addition of acrylic acid and crosslinking with MBA had a significant effect on swelling, gel fraction, and mechanical properties at a significant level of 5%. FTIR confirmed the chemical interaction comprising acrylic-acrylamide acid andMBA in cassava pulp. In line with the analysis, the best treatment was obtained from 25% acrylic acid percentage and 0.5% MBA concentration with 1058% swelling value and 70.05% gel fraction. This hydrogel had a hardness of 6.46 mJ, 5.39 kPa modulus of elasticity, and 4.34 x 1023 m-3 active bonds per unit volume, showing the potential for use in agricultural fields as a planting medium, water carrier, and fertilizer protector.

Abstract

The development of bioplastics has continued to grow as an alternative material based on renewable natural resources. Cellulose is a natural polymer that is widely used as a raw material for bioplastics; however, cellulose-based bioplastics generally show limited mechanical stability and rigidity. Therefore, the addition of chitosan and glycerol is required to improve their characteristics. This study aims to determine the cellulose content and functional groups of banana stem cellulose and to analyze the effect of chitosan concentration on the thickness, mechanical properties, and degradation rate of banana stem cellulose-based bioplastics using glycerol as a plasticizer. Bioplastics were synthesized by varying the chitosan concentration at 1%, 2%, 3%, and 4%. The results showed that the cellulose content of banana stems reached 93%, with the presence of –OH, –CH, and –CO functional groups. The variation in chitosan concentration affected the thickness, tensile strength, elongation at break, and degradation rate of the bioplastics. An increase in chitosan concentration resulted in a decrease in thickness and elongation, while tensile strength and degradation rate increased with higher chitosan content. These results indicate that chitosan concentration significantly influences the physical, mechanical, and degradation properties of banana stem cellulose-based bioplastics, demonstrating their potential as biodegradable materials.

Abstract

Wound healing is a complex biological process in which wound dressings play a vital role in providing protection and supporting tissue regeneration. In this study, cassava dregs waste was utilized as a base material for the development of hydrogel wound dressings. The hydrogel was incorporated with black pepper (Piper nigrum) extract to enhance its antibacterial properties. Sample preparation consisted of several stages, including cassava dregs processing, hydrogel synthesis, and extraction of black pepper using the maceration method. The hydrogel was characterized in terms of swelling capacity, gel fraction, swelling kinetics, antibacterial activity against Staphylococcus aureus, functional group identification using Fourier Transform Infrared (FTIR) spectroscopy, and morphological analysis. The results demonstrated that the incorporation of black pepper extract significantly affected the swelling behavior of the hydrogel, with swelling capacities ranging from 263.76% to 387.87%. The hydrogel exhibited a high gel fraction of 86.13% and favorable swelling kinetics with a kinetic constant of 0.5443. Variations in black pepper extract volume were evaluated, including 0 ml (control), 20 ml, 40 ml, and 60 ml. These findings indicate that cassava dregs–based hydrogels enriched with black pepper extract have promising potential as antibacterial wound dressing materials.

Abstract

Higher education plays an important role in improving human resource quality and social mobility. However, participation in higher education among Indonesian high school graduates remains relatively low, particularly in peripheral regions such as South Bangka Regency. This study aimed to explore the role of teachers in fostering Grade XII students’ motivation to pursue public universities. A descriptive qualitative approach was employed involving 14 participants, including principals, homeroom teachers, guidance counselors, and students from senior high schools in South Bangka Regency. Data were collected through semi-structured interviews and analyzed using thematic analysis based on the Miles and Huberman model. The findings revealed that students’ motivation to continue to public universities was generally fragile and unstable. Although many students aspired to pursue higher education, their decisions were often constrained by financial limitations, parental influence, limited access to information, and socio-cultural norms that prioritized immediate employment. Teachers, counselors, principals, and school programs played significant roles in strengthening motivation through encouragement, guidance, and exposure to higher education opportunities. In this context, schools functioned as strategic institutions that helped bridge gaps in information and educational access. The study concludes that increasing higher education participation requires more than financial assistance alone. Strengthening structured career guidance, teacher capacity, parental involvement, digital information access, and collaboration between schools and universities is essential to support students’ transition to higher education, particularly in underserved and peripheral regions.
