Characteristics of Briquettes Made from Plastic Waste, Plastic-Coconut Shell Blends, and Plastic-Corn Cob Composites
Get PDFRecycling plastic waste holds considerable potential as a fuel source, especially when combined with agricultural waste. This study aims to evaluate the physical characteristics of charcoal briquettes - moisture content, ash content, volatile matter, calorific value, and fixed carbon content - produced from a mixture of plastic waste and organic waste. Three composition variations were tested: pure Low Density Polyethylene (LDPE) plastic waste (100%) as the first treatment (S1), a combination of coconut shells and plastic waste in a 50%:50% ratio as the second treatment (S2), and a combination of corn cobs and plastic waste in the same 50%:50% ratio as the third treatment (S3). Testing was conducted according to SNI 01-6235-2000 standards. The results showed that all treatments produced charcoal briquettes with moisture content and calorific value that met SNI standards. Among the treatments, briquettes made entirely from plastic waste (S1) achieved the highest calorific value at 5921 cal/g, followed by the plastic-coconut shell mixture (S2) at 5574 cal/g and the plastic-corn cob mixture (S3) at 5100 cal/g. These findings indicate that plastic waste and agricultural waste have significant potential as fuel sources for power generation, supporting energy mix targets, and contributing to waste management and sustainable energy production. However, the study also identified areas for improvement. The ash content across all treatments failed to meet SNI standards, and the volatile matter content in S1 was below the acceptable range. These shortcomings highlight the need for further optimization in material formulation and manufacturing processes to enhance briquette quality. Future research should prioritize refining material combinations, improving ash content and volatile matter characteristics, and assessing the environmental impacts of using plastic-based briquettes. With continued innovation, this approach could play a pivotal role in achieving energy mix targets and addressing the challenges of plastic and agricultural waste, offering a sustainable and practical solution for energy generation
Bioactivity Analysis of Chalcone-Derived Compounds Based on In-Silico Molecular Docking Study
Get PDFChalcone compounds are aromatic ketones and enones that have been found to have several activities, such as antimalarial, antioxidant, anti-inflammatory, anticancer, antiviral, anti-HIV, antifungal, antihyperglycemic, and carboxygenase inhibitors. A ligand's bioactivity can be predicted through in-silico tests using molecular docking. Molecular docking studies are conducted to study the interaction between ligand and receptor and identify the receptor's active site that matches the ligand when the ligand and receptor bind in a stable complex. This study can be a preliminary test before conducting in vitro and in vivo tests. This narrative review aims to analyze information on the bioactivity of chalcone-derived compounds and their derivatives through an in silico molecular docking approach in the form of binding affinity values and amino acid residues that bind. The method used is a literature study of 13 research articles found through the Semantic Scholar and Springer Link databases. The review results showed that the new compounds derived from chalcone compounds have a good range of bioactivity, as seen from the binding affinity values, which show lower values when compared to other test ligands and referenced ligands. The functional groups that have an important role in the interaction between ligands and proteins between ligands and receptors are triazole, methoxy, amine, halogen, carbonyl, hydroxyl, and thiol groups bound to the reactive structure of the α,β unsaturated ketone aromatic ring in the structure of the chalcone compound. The compounds that show promising activity can be further investigated as new drug candidates

No full textScience learning in elementary schools often faces challenges in delivering abstract materials such as the solar system, especially due to the limited availability of interactive and interesting media. To overcome this, this study developed Prezi-based learning media assisted by virtual reality and songs as learning aids that are expected to improve students' understanding and learning experience. This study uses a development research method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research stages include needs analysis, media design, product development, implementation in learning, and evaluation of the effectiveness of the media developed. Prezi media assisted by Virtual Reality and songs were tested through a series of validity and effectiveness tests to assess their quality in supporting learning. The results of expert validation showed that the media developed was categorized as very feasible, with a feasibility percentage reaching 92.85% from media experts and 93.75% from material experts. The validated media was then implemented in class 6 of SDN 6 Wulung with a population of 24 students. The results of the normality test showed a significance value above 0.05, which indicates that the data on all test results that had been carried out were normally distributed. There was an increase in learning scores as evidenced by the paired t-test value, which showed a value of 0.014 in small-scale classes and 0.000 in large-scale classes. In the N-Gain test conducted, the figure was 0.72, which is considered high in small-scale classes, and 0.69, which is considered moderate in large-scale classes. The use of Prezi and virtual reality technology combined with songs has been proven to be able to increase students' grades, interests, and involvement in learning. Thus, this media has the potential to be an innovative alternative in teaching science at the elementary school level. This study recommends further testing with a wider scope to ensure the sustainability and effectiveness of media use in various learning conditions
