Abstract

Technology continues to experience rapid development as times progress. The utilization of technology also continues to spread to all fields and aspects of human life. The use of technology helps various aspects to develop existing opportunities. In addition, human resource management (HRM) is very important for running company or organizational activities so that everything runs well and achieves targets. To succeed in a field, the implementation and development of human resources based on technology is needed in order to create quality human resources. In the current era, technology helps businesses to carry out more efficient digital innovations. Optimizing the use of technology became our main focus when conducting KKM-PKM activities in Kuala Mandor village. This proposal suggests a series of innovative activities aimed at developing the existing potential in Kuala Mandor village. The implementation of our work program also involves the participation of Kuala Mandor villagers. The innovative steps we take are providing education and digitalizing social media accounts for SMAN 1 Kuala Mandor and Keramba Cipta Mandiri. With this innovative step, Kuala Mandor village is expected to develop into a productive village and have a positive impact on the people involved.

Abstract

Fly ash has been highly advocated to be re-utilized as a construction material. The most common utilization is to partially replace cement in a low-percentage scheme. However, there are several other schemes available to potentially use fly ash as binder in concrete that have not been widely exercised, especially those utilizing it in high to very high volume. In those schemes, high-volume fly ash (HVFA) concrete might use more than 50% fly ash to replace cement. To exploit its self-cementing properties, with or without the addition of other compounds, such as calcium hydroxide, fly ash might be used in very high percentage of cement replacement. In geopolymeric system, fly ash acts as the precursor of a stable binder, with the presence of highly alkaline solution. This paper demonstrates a model to investigate the potential of fly ash in several binder systems. The results show that fly ash from a good source can be utilized as an alternative binder in several different schemes.

Abstract

Elevated blood cholesterol levels are known to be a major risk factor for cardiovascular disease. Hypercholesterolemia can trigger atherosclerosis, which in turn increases the risk of coronary heart disease and stroke. One approach to managing cholesterol levels is through the use of natural ingredients with antihyperlipidemic activity. White turmeric (Curcuma zedoaria Rosc) is an herbal plant long used in traditional medicine and contains bioactive compounds such as curcuminoids and essential oils. These compounds are reported to have antioxidant and anti-inflammatory activities, as well as potential as agents for lowering blood lipid levels. Herbal-based therapies are increasingly considered as safe alternatives to synthetic drugs in managing hyperlipidemia. This study aims to evaluate the effectiveness of a microencapsulated preparation of white turmeric ethanol extract in reducing total cholesterol levels in male rats (Rattus norvegicus) induced by a high-fat diet. The study was conducted experimentally using 25 rats divided into six treatment groups. The groups consisted of normal controls, negative controls, positive controls using simvastatin, and three treatment groups given white turmeric extract microcapsules at concentrations of 0.25%, 0.50%, and 0.75%. The microencapsulation technique was applied to improve the stability and bioavailability of the turmeric extract. Cholesterol levels were measured before and after treatment. The results showed that the treatment group with the 0.25% concentration produced the most significant cholesterol reduction, from 110 mg/dL to 59 mg/dL. These findings indicate that even at a relatively low concentration, microencapsulated turmeric extract can significantly reduce cholesterol levels in vivo. Therefore, it can be concluded that white turmeric extract in microcapsule form is effective in lowering total cholesterol levels, especially at the 0.25% dose. This suggests that Curcuma zedoaria microcapsules hold promise as a natural therapeutic option for managing hypercholesterolemia and reducing cardiovascular risk.
