Abstract

Agifa Roti is one of the small and medium enterprises (SMEs) engaged in the food industry, located in Warungboto, Umbulharjo District, Yogyakarta City, Special Region of Yogyakarta. The products produced are in the form of basic ingredients for sweet bread, in the production process it is still traditional without using the help of machines only during the baking process using a gas-fueled oven and mixer to make dough. facing waste constraints in the sweet bread production process, especially in waiting activities (31.07%) and transportation (8.90%). This waste is caused by the less than optimal layout of facilities, with a distance of movement between work stations reaching 810.99 cm. This study aims to identify waste, reduce waste, and increase production efficiency through the application of the Lean Manufacturing method with the Value Stream Mapping (VSM) approach including the calculation of Material Handling Costs (OMH) to assess cost efficiency. Research methods related to cycle time, lead time, changeover time, and facility layout. Based on the research results, it shows that the application of the Lean Manufacturing method with the VSM approach is able to reduce the distance of movement between work stations by 29.2%, production cycle time by 61.2%, and material handling costs significantly, thereby increasing efficiency, reducing waste, and providing real benefits for the productivity and competitiveness of Roti Agifa MSMEs and similar MSMEs.

Abstract

The development of technology and digital communication has transformed social interactions among adolescents, particularly through sexting behavior, defined as the sending and receiving of sexually explicit messages, images, or videos via electronic devices. This study aims to explore sexting trends among adolescents in Makassar City. The research method employed is a survey, systematically collecting data from a representative sample of adolescents aged 12 to 18 attending various junior high and high schools. The results indicate that sexting behavior is relatively common among adolescents, with factors such as peer influence and access to social media significantly contributing to its prevalence. The conclusion emphasizes the importance of education and policy implementation in schools to address sexting issues, as well as the need for effective prevention programs. The contribution of this research lies in providing a better understanding of sexting behavior among adolescents and offering recommendations for interventions that can be undertaken by educators and parents. Keywords: Sexting; Adolescents; Digital Communication; Social Media; Prevention Strategies
