Abstract

Setelah berakhirnya Covid-19, perlu dilakukan pendampingan kepada anak didik dalam menyesuaikan diri dengan masa kenormalan baru. Proses adaptasi dari daring ke luring menimbulkan kesulitan bagi anak-anak. Salah satu kuncinya adalah pola asuh yang berperan penting dalam perkembangan anak usia dini, termasuk karakter anak. Pengabdian ini bertujuan untuk meningkatkan pola asuh dengan mendorong partisipasi orang tua dalam kegiatan belajar mengajar anaknya. Sosialisasi terkait parenting, kegiatan menyiapkan sarapan bersama, dan mengajar wali murid dilakukan. Dengan adanya kegiatan tersebut diharapkan komunikasi dan pola asuh yang efektif antara orang tua dan anak dapat memperlancar proses belajar mengajar di sekolah.

Abstract

Indonesia’s archipelagic environment subjects concrete structures to severe corrosion and sulfate attacks, necessitating sustainable repair solutions. This study evaluates a geopolymer-based bio-patch repair mortar utilizing fly ash (FA), rice husk ash (RHA), and Bacillus subtilis bacteria to induce Microbially Induced Calcite Precipitation (MICP). While the silica-rich ashes act as pozzolanic materials, the bacteria enhance durability by reducing oxygen levels and lowering corrosion rates. Microscopic analysis confirmed the formation of calcium carbonate ($CaCO_3$) and calcium silicate hydrate (C-S-H), both of which significantly improve mechanical properties. The research identified an optimum mixture of 93% FA, 6% RHA, and 1% bacteria, which achieved a compressive strength of 30 MPa, a density of 2.32 g/cm³, and a low water absorption rate of 3.25%. These results meet standard performance requirements, demonstrating that this eco-friendly geopolymer-MICP system is a viable and innovative contribution to structural repair in aggressive environments.
