Geometric transformation is an important topic in mathematics that students must master. However, many students find it difficult to understand geometric transformations abstractly. Thus, the purpose of this research is to develop a learning trajectory that facilitates students' understanding of geometric transformations by using the context of Tayub Dance and GeoGebra media for ninth-grade students at junior high schools in Semarang. The approach applied is Realistic Mathematics Education (RME)...

Mathematical problem solving ability through teams games tournament assisted by gimkit based on mathematical resilience
Mathematics is a universal science that underlies the development of modern technology and plays an important role in advancing human thinking. One essential ability for students is mathematical problem-solving ability. However, In reality, Indonesian students' mathematical problem-solving ability is still considered low, partly due to the implementation of less effective teaching approaches. Therefore, innovation is needed through the implementation of the Teams Games Tournament (TGT) learning...

Cooperatives, as a pillar of the people’s economy, play a strategic role in improving community welfare. However, in practice, cooperatives still face various challenges, particularly in terms of digitalisation and the limited capacity of human resources (HR). This community service activity aims to enhance digital literacy and HR capacity through assistance in implementing a digital-based financial system at Koperasi Merah Putih in Karanganyar Gunung, Semarang City. The method employed is a par...

Supply Chain Performance Evaluation in the Pulley Manufacturing Industry Using Supply Chain Operations Reference and Analytical Hierarchy Process
Supply chain performance is critical to the efficiency of make-to-order manufacturing systems, where waste such as waiting, rework, unnecessary motion, overprocessing, and transportation still occurs at several workstations. These inefficiencies prolong production time and reduce overall effectiveness. This study aims to measure supply chain performance, determine the relative importance of performance metrics, and establish improvement priorities. The research integrates the Supply Chain Operat...

This study evaluates the role of computational pattern recognition as an observational method for analyzing morphological characteristics of brain tumor tissue in MRI data. A total of 6,056 labeled MRI images, including glioma, meningioma, and pituitary tumor cases, were examined. The images were standardized to maintain uniform structural representation and processed using three convolutional-based architectures: a baseline CNN, MobileNetV2, and EfficientNet-B0. Model performance was assessed u...

In vitro antifungal activity of Mimosa pudica rhizosphere bacteria against Fusarium spp.
This study aims to explore rhizosphere bacteria from Mimosa pudica L. as a source of antagonistic bacteria against Fusarium spp. Rhizosphere soil samples were collected, isolated, morphologically characterized, and tested for antifungal activity in vitro against Fusarium spp. The percentage of inhibition (PI) was calculated after 7 days. Six bacterial isolates were obtained and tentatively identified as Bacillus, Cellulomonas, Arthrobacter, and Micrococcus species. All isolates exhibited antagon...

Evidence-based non-residential waste analysis to support 3R strategies and food recovery hierarchy: a case study in Solok Selatan
The amount of waste generation that increases without being accompanied by good waste management will cause pollution and decrease the aesthetic value of the environment. Non-residential waste originating from non-residential activities is also one of the contributors to waste entering the landfill. This study aims to analyze non-residential waste generation and composition as an evidence-based reference for each source in implementing the 3R concept and the Food Recovery Hierarchy (FRH). The nu...

Utilization of cassava peel waste (Manihot esculenta) as substrate in the production of cellulase enzymes by Aspergillus niger
Cellulase enzymes is an enzyme that can hydrolyze cellulose into smaller sugar components. Cellulase enzymes are produced due to high demand, with 29.17% in the animal feed industry, 14.67% in the textile industry, and 26.17% in the paper industry. One method of producing cellulase enzymes is by utilizing the cellulolytic microorganism Aspergillus niger. This study aims to optimize cellulase enzyme production by Aspergillus niger through liquid fermentation on cassava peel substrate (Manihot esc...
