Abstract

Rhizomes are one of the main ingredients in the production of traditional herbal medicine, which plays an important role in the food, beverage and medicine industries. The process of drying rhizomes greatly affects the quality and shelf life of the product, so an efficient drying device is needed to ensure optimal quality. This research aims to design a rhizome drying tool for traditional dipping herbal medicine production houses, which can speed up the drying process and maintain the quality of the rhizomes produced. This type of research is development research with the research object being rhizomes used in herbal medicine production. Data was collected through testing the designed tool, using temperature and drying time testing methods. Data analysis was carried out by measuring the quality of the rhizomes post-drying, including moisture and color. The research results showed that the designed dryer was capable of drying rhizomes at a temperature of 40°C within 1 hour, while maintaining the quality of the rhizomes and meeting the standards for herbal medicine production. In conclusion, this tool has the potential to be a practical solution for traditional herbal medicine production houses, speeding up the production process and increasing efficiency.

Abstract

Indonesia has tropical climate characteristics, so it requires a cooling device where the utilization can be used as a room cooler and storage. Cooling machines generally use refrigerant working fluid in the compressor, refrigerant is a gas that is not environmentally friendly. So it is necessary to conduct alternative studies, that can replace refrigerant gas and simplify dimensions, weight, and convenience. This study was conducted to analyze the effect of applying a power supply on the performance of thermoelectric coolers. The experimental method applied 2 types of power supplies for thermoelectric Peltier coolers in cooling the mini cooler box space, then the 1400 ml capacity cooling room was given a varying volume of drinks. Analysis of the effect of using a power supply on the cooling performance of the mini cooler box on the thermoelectric Peltier system obtained the results that the time to reach the ambient temperature takes different times. The greater the load put into the box, the longer it takes to cool the drinking water. The greater the power supply ampere specifications, the better it is in accelerating the cooling rate but the power required is greater such as the application of the type of power supply with the type 20A.

Abstract

Starting from the limitations of real learning media in learning, this study aims to explore students' perceptions of the use of Mini Cultivator as a learning medium. The research method used is quantitative using the urgency, seriousness, and growth (USG) matrix. The data collection technique uses a questionnaire. The results of the study showed that students' perceptions on the aspect of media effectiveness received the highest priority with a percentage of 25.07%, followed by motivation at 25.06%, usefulness at 25.04%, and innovation at 24.81%. Students' positive perceptions of Mini Cultivator media are reflected in the results of the USG analysis. The results of the assessment on the "urgency" dimension indicate students' awareness of the importance of using Mini Cultivator in learning. The "usefulness" dimension shows that students see Mini Cultivator media not only as an addition, but as an important element in learning. The "development" aspect shows that Mini Cultivator media is relevant and closely related to the topic or concept being studied.

Abstract

Composite polymers are now under development and are widely used in automobile manufacturing for interior panels, door panels, and bodywork. The research and development of polymer composites for the automobile manufacturing must have resilient fire resistance requirements. Currently, polymer composites with fire resistance capabilities have been developed with geopolymer materials, which offer benefits and produce excellent performance. Geopolymers are inorganic polymers that contain aluminosilicates, silica oxides, and alumina oxides. They have thermally resistant mechanical characteristics. Geopolymer materials are commonly derived from waste materials, including those utilized as additions to polymer composite materials, specifically coal fly ash and clay-based waste. The purpose of this literature is to discuss the path and progress of waste-based polymer reinforced composite technology for fire resistance. The methodology employed in this study takes a conceptual approach to articles on the influence of adding different types of geopolymer materials on the fire resistance properties of natural fiber reinforced composites. According to the findings, articles involving the inclusion of geopolymer materials tend to lower resistance to tensile and flexural stresses, whilst the addition of this geopolymer material reduces fire resistant qualities.
