Abstract

Istana Qur’an adalah Pesantren Muhammadiyah modern di Desa Sarwodadi, Kecamatan Pejawaran, Banjarnegara, Provinsi Jawa Tengah. Pesantren ini merupakan salah satu amal usaha yang didukung oleh Pimpinan Cabang Muhammadiyah (PCM) Pejawaran, sebagai mitra dalam proyek pengabdian masyarakat ini. Berdasarkan letak geografisnya, pesantren ini dekat dengan kawasan wisata Dieng Banjarnegara sehingga dapat dijadikan sebagai penyangga destinasi wisata di kawasan Dieng. Selain itu belum ada situs Muhammadiyah yang secara serius dikembangkan menjadi kawasan edu-tourism padahal Desa Sarwodadi ini memiliki potensi yaitu adanya pondok pesantren Muhammadiyah yang dikembangkan. Oleh karena itu, tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk memberdayakan mitra berupa pendampingan dalam penyusunan site plan edu-tourism Muhammadiyah sesuai kaidah teknis yang berlaku di Indonesia serta memperhatikan tata guna lahan dan lingkungan untuk edu-tourism. Kegiatan yang dilakukan berupa survey foto udara dengan peta drone, Forum Group Discussion (FGD), dan penggambaran teknis menggunakan program berbasis CAD. Semua kegiatan berjalan dengan baik dan berdasarkan hasil evaluasi, pengabdian masyarakat ini dapat meningkatkan pengetahuan mitra dari 6,2% menjadi 94,2% setelah selesainya terbentuknya site plan edu-wisata.

Abstract

Corrosion and carbonation pose significant risks to reinforced concrete structures, necessitating timely patch repairs, especially when using seawater-mixed mortar. This study evaluated the influence of binder type, cover thickness, corrosion protection methods, and exposure conditions on the durability of reinforced concrete. Specimens using Portland Pozzolan Cement (PPC) and Portland Composite Cement (PCC) with 3 cm and 5 cm cover depths were tested over 400 days. PCC exhibited superior corrosion resistance due to its higher CaO content, enhancing strength, reducing permeability, and limiting chloride ion ingress. Surface concrete coatings were the most effective in mitigating carbonation, limiting carbonation depth to 0.38 cm, while steel-coated and uncoated specimens showed greater depths of 0.50 cm and 0.55 cm, respectively. Exposure conditions significantly influenced performance, with dry and dry-wet cycles accelerating carbonation, while wet conditions provided better protection. The findings recommend PCC-based mortar combined with surface coatings for patch repair applications to improve long-term durability in marine environments.
