Abstract

The program is an initiative to improve English language skills among students and educators in rural schools. The background to this program is limited access to effective English language learning in rural areas, which has an impact on students' low English language skills and limited opportunities to compete at a wider level. This program implements interactive, contextual and participatory learning methods, specifically designed to meet learning needs in rural areas. Through various activities such as basic English training, conversation sessions, daily interaction simulations, and teacher involvement in mentoring, this program provides an interesting and applicable learning experience for students. By involving the school community and the surrounding environment, this program is expected to create a sustainable impact, strengthen students' and teachers' confidence in using English, and prepare them for various educational and employment opportunities in the future. The community-based approach in this program not only benefits students, but also empowers educators to adopt more engaging and contextual teaching techniques. Through ongoing evaluation, it is hoped that this program can become an effective English language learning model in rural areas.

Abstract

Plastic waste is one of Indonesia’s most critical environmental challenges, comprising approximately 17% of the nation's 64 million tons of annual waste. This study explores the impact of a recycling workshop that transformed plastic waste into handicrafts, conducted at the Malang Waste Bank and involving students from Universitas Kristen Cipta Wacana Malang. Using an activity-based participatory approach, the workshop aimed to enhance students’ environmental awareness, practical recycling skills, and understanding of circular economy principles. Data were collected through observations, interviews, questionnaires, and documentation. The results showed a significant increase in students’ knowledge of the 3R concept (Reduce, Reuse, Recycle), along with improved technical skills in sorting, melting, and crafting recycled products such as bags, hats, and wallets. The workshop also encouraged environmental entrepreneurship by demonstrating that waste can be transformed into valuable and marketable items. This initiative exemplifies how community-based, hands-on learning experiences can foster sustainability values in higher education and support the Merdeka Belajar Kampus Merdeka (MBKM) policy framework.

Abstract

This study aims to analyze the effect of varying wind speeds on the power output generated by a Vertical Axis Wind Turbine (VAWT). This type of turbine holds great potential for harnessing wind energy in both urban and rural areas, particularly due to its ability to operate under fluctuating wind directions. The methodology employed is numerical simulation based on Computational Fluid Dynamics (CFD), which models fluid flow around the turbine rotor at wind speeds ranging from 2 m/s to 12 m/s. Key parameters analyzed include power coefficient (Cp), torque, and mechanical power output. The simulation results indicate a nonlinear relationship between wind speed and power output, where increasing wind speed significantly enhances power up to a certain optimum point, beyond which turbulence and energy losses become more dominant. These findings provide a foundation for optimizing VAWT design and selecting suitable installation sites according to local wind conditions. This research also supports the development of sustainable and environmentally friendly renewable energy technologies, particularly for small- to medium-scale applications.
