Abstract

The IbM Program for Product Assistance and Training in the Manufacture of Galvalum Roof Composites Using Roof Tile Powder for the students of Pondok Pesantren Darul Muttaqin Batu aims to improve their technical skills and entrepreneurial spirit by utilizing roof tile powder waste as a composite filler material. The partner’s problems include limited knowledge of composite technology, the absence of innovative pesantren–based products, and inadequate production facilities. The activities were carried out through needs analysis, the design of a roof tile powder–resin composite formula, the provision of equipment and material packages, theoretical and practical training, and assistance with product quality testing and packaging. The method used was a participatory approach, so the students were directly involved in all stages of the production process, from material preparation through mixing, molding, finishing, and evaluation. The results show an increase in students’ knowledge regarding composite material concepts, safe working procedures, and quality control. The students were able to produce prototypes of galvalum roof composites with roof tile powder that are relatively light, visually uniform, and have smoother surfaces compared to products made before the program. The partner’s response was very positive, as shown by their commitment to integrating the training into regular skill activities and exploring collaboration with building material entrepreneurs. A small production team was formed, with the potential to develop into a pesantren-based business unit, thereby contributing to economic self-reliance and entrepreneurial opportunities for students.

Abstract

The extensive use of galvalume roofing in Darul Muttaqin Batu Islamic Boarding School offers practical advantages, including light weight, durability, and ease of installation. Nevertheless, this metallic roofing material can reduce thermal comfort because rooms beneath the roof become hotter during strong solar exposure. This community service program aimed to introduce a sand-epoxy composite coating as a simple technology for reducing heat transfer through galvalume roofing while serving as a practical learning medium for students. The activity included a partner needs assessment, preparation of tools and materials, a theoretical explanation, a demonstration of sand-epoxy mixing, hands-on coating practice on galvalume sheets, and evaluation of participant responses. Sand was selected as the filler because it is inexpensive, locally available, and feasible for use in an epoxy matrix. The results showed that students could understand the basic concept of composite materials, identify the function of each component, and conduct the coating process under technical supervision. A trial application in a 2 x 5 m room showed a decrease in air temperature, making the room more comfortable to use. In addition to producing a prototype of sand-epoxy-coated galvalume roofing, the activity improved students' awareness of how local materials can solve technical problems in the boarding school environment.
