Many brewing methods require knowledge to practice them. So by creating a game that includes how to make coffee using manual brewing techniques and doing commercial photography a day, it is an incentive for coffee sales. Photography here plays a very important role in the world of advertising in order to get attractive visuals to attract the interest of potential consumers. The work creation method is used to produce work that suits the purpose to be conveyed. The process of exploration and improvisation with manual coffee brewing objects will be collaborated without eliminating the main functional aspects. Through the final task of creating this product photography work, produce commercial photos that are able to make the wider community more familiar with manual coffee brewing products which are usually available in coffee shops and help those who don't know how to brew coffee using manual brewing techniques, and can also as initial capital for young people who want to become baristas to complete the stages of making coffee using the Manual Brewing.

Abstract

Cooking oil is a staple food widely used in daily cooking. However, repeated use of cooking oil, resulting in its conversion into used cooking oil, can have negative impacts on both health and the environment. Used cooking oil that has changed color and quality is carcinogenic and has the potential to increase the risk of cardiovascular disease if consumed again. Furthermore, improper disposal of used cooking oil can cause environmental pollution because it is difficult to decompose. This study aims to examine the wise management of household waste, especially used cooking oil, by utilizing it into products with utility value. One form of utilization is processing used cooking oil into environmentally friendly soap for laundry purposes. This activity was carried out as a form of community service through training in making soap from used cooking oil with the addition of essential oils for aromatherapy for residents of Pasar Rawa Village, Gebang District, Langkat Regency. The research method used was qualitative, with observation and direct participation in the training activities. The results showed that participants, particularly housewives, demonstrated high enthusiasm and were actively involved in both the presentation and the soap-making practices. This activity not only raised public awareness of the importance of managing used cooking oil waste but also provided new skills that have the potential to support family economic growth.

Abstract

This study aims to examine the use of Macaulay2 software in improving students' computational thinking skills in mathematics learning, especially in abstract algebra material. Macaulay2 as an open-source Computer Algebra Sistem (CAS) provides a symbolic and algorithmic environment that encourages logical and systematic exploration of mathematical concepts. Literature reviews show that the use of Macaulay2 can strengthen conceptual understanding, train computational thinking, and introduce mathematical programming to students. However, technical challenges, limited Indonesian language teaching materials, and limited educational infrastructure are obstacles that need to be overcome through collaboration between educational stakeholders.
