This Community Partnership Program (PKM) aims to improve the competence of mathematics teachers at Madrasah Tsanawiyah (MTs) in Lumajang Regency in developing ethnomathematics-based teaching materials integrated with Augmented Reality (AR) technology. This program was initiated due to the minimal use of local culture in mathematics learning and the low ability of teachers to develop innovative teaching materials. The activity was carried out in four main stages: socialization, training, technology application, and mentoring and evaluation. The training included an introduction to the concept of ethnomathematics, the preparation of differentiated teaching materials, and the creation of AR-based learning media using Unity 3D, Blender, Geogebra, and Vuforia. The results of the activity showed an increase in teachers' understanding of the concept of ethnomathematics and their ability to integrate the local cultural values of Lumajang into mathematics learning. In addition, teachers successfully produced contextual AR-based interactive teaching materials in line with the spirit of the Merdeka Curriculum. This activity also strengthened collaboration between lecturers, students, and teachers of the MTs Wilker III Mathematics MGMP and became a model for continuous training in the development of innovative learning media based on local wisdom and digital technology.

Low English proficiency remains a problem for the younger generation in Mimika Regency, particularly in speaking skills. Additionally, the flow of modernization influences the low appreciation of society, especially the younger generation, towards local culture, with the emergence of popular culture. This community service activity offers an English Storytelling Competition as a creative and innovative educational medium to integrate English competency and the preservation of the local culture of indigenous communities in Mimika Regency. This program used a collaborative approach/community-based participatory approach (CBPA) through community involvement in the planning, script preparation, workshops, competitions, and reflection stages, together with the utilization of existing local strengths and wisdom. The main purpose of this program is to encourage social change in the community, which includes: (1) increasing oral English skills in the young generation in Mimika. (2) the presence of awareness and pride in the importance of preserving local culture, and (3) the creation of a community environment that provides appreciation for local cultural products that grow together with global challenges. The results of the activity showed an increase in English communication skills, growing self-confidence in students, and the presence of creativity in interestingly packaging Amungme-Kamoro folklore. In addition, this activity brings a new awareness of the importance of preserving local culture, potential leaders who dare to appear in public, and presents a new institution in the form of a space competition that combines aspects of language and cultural education.

Green Companies are a necessity for businesses to ensure sustainability in environmental management, preventing pollution and environmental damage during construction, production, or when products or services are used by customers, even up to the point of disposal. To provide satisfaction to tourists, tourist attractions must have adequate facilities to support the needs of tourists during their visit and to fulfill their expectations. Green industries and tourism play a crucial role in local economic development and environmental conservation. This study aims to provide assistance to green industries and tourism facilities in Kampung Batik Malon, focusing on sustainable development and empowerment of the local community. Assistance is provided through skills training to improve the quality of batik products and introduce environmentally friendly production techniques. In addition, the development of tourism facilities, such as homestays based on local culture and interactive batik galleries, is implemented to enhance the attractiveness of the tourist destination. Local community empowerment is carried out through participation in the decision-making process and the establishment of cooperatives to improve market access. The assistance also involves a sustainable approach to managing industrial waste and promoting environmentally friendly practices. The results of this assistance implementation show a significant increase in the quality of batik products, an increase in the number of tourist visits, and an increase in the income of the local community. Additionally, Kampung Batik Malon has successfully reduced its environmental impact through more sustainable production practices. Therefore, this activity contributes to sustainable development by demonstrating that the integration of green industries and tourism can be a successful model for strengthening the local economy while preserving the environment. Furthermore, this research provides guidance for other villages that wish to adopt a similar approach in developing the local potential of tourist attractions.
