Micro, small, and medium enterprises (MSMEs) contribute more than 60% of Indonesia’s gross domestic product and absorb approximately 97% of the national workforce, yet most micro-entrepreneurs remain constrained by weak business planning, limited understanding of Islamic commercial principles, and low digital marketing literacy. This community service programme aimed to strengthen the sharia-based entrepreneurial capacity of members of the Muhammadiyah Branch Board (PCM) of Mustika Jaya, Bekasi City, through structured training and guided business plan development. The implementation consisted of four stages: socialisation and baseline data collection, interactive structured training, mentoring in business plan preparation, and evaluation through pre-test, post-test, and assessment of business plan quality. Thirty-five participants attended; 23 completed both the pre-test and post-test, and 25 submitted a business plan. Evaluation results showed an average increase of approximately 20% in participants’ understanding of entrepreneurship, Islamic business principles, and digital marketing. The collected business plans covered five business clusters, namely halal culinary (9 plans), retail and groceries (7), services (5), Muslim fashion and worship supplies (3), and waste management (1), and consistently articulated a commitment to avoiding riba, fair pricing, transparent contracts, and the planned use of Instagram, WhatsApp Business, and TikTok. The programme demonstrates that integrating entrepreneurship, muamalah, and digital marketing content within a single training series effectively produces applicable business plans while supporting the achievement of SDGs 1, 8, and 12.
