Abstract

Conventional fired-clay brick production in Lancang Barat Village, Dewantara District, North Aceh Regency, continues to face challenges, including high energy consumption, inconsistent product quality, and the underutilization of Aceh flood sediment and rice straw waste. This community service program aimed to enhance the capacity of local brickmakers through the transfer of Compressed Stabilized Earth Block (CSEB) production technology using Aceh flood sediment and rice straw fibers as sustainable construction materials. A participatory approach was employed, consisting of community outreach, training, technology demonstrations, hands-on production practice, technical assistance, basic quality testing, and evaluation through pre-tests, post-tests, and participant satisfaction questionnaires. The program resulted in improved knowledge and technical skills among participants, the development of training modules and Standard Operating Procedures (SOPs), the establishment of a group of brickmakers capable of independently operating the technology, and the production of interlocking CSEBs that met the basic requirements for non-structural construction. The program also promoted circular economy practices through the utilization of local waste resources, reduced dependence on fired-clay bricks, and demonstrated strong potential for replication in other regions with similar characteristics.

Abstract

Abstrak Korosi pada struktur beton betulang dapat mengurangi kinerja struktur dan umur layannya karena volume tulangan yang berkurang. Besarnya jumlah korosi yang dipengaruhi oleh laju korosi dapat digambarkan melalui besarnya densitas arus yang terjadi. Jumlah korosi yang terjadi mempengaruhi perilaku retak pada beton bertulang, oleh karen itu, pada studi ini dilakukan uji eksperimental untuk mengevaluasi pengaruh densitas arus terhadap perilaku retak permukaan beton dari struktur beton bertulang yang mengalami korosi tulangan. Pengujian dilakukan dengan mengaplikasikan variasi densitas arus yaitu 900 µA/cm2, 500 µA/cm2, 200 µA/cm2 and 100 µA/cm2 pada pengujian korosi secara elektrik menggunakan larutan NaCl sebagai elektrolit untuk menghasilkan ion Cl-. Benda uji yang digunakan adalah balok dengan luas penampang 150x150 mm2 dan panjang benda uji 300 mm. Tulangan baja diameter 19 mm digunakan pada tengah penampang. Hasil pengujian menunjukkan bahwa perilaku retak dari beton bertulang yang mengalami korosi pada tulangannya memiliki kurva yang bilinear. Selain itu, hasil pengujian menunjukkan bahwa densitas arus yang rendah memiliki kecepatan retak permukaan beton yang lebih tinggi jika dibandingkan dengan benda uji dengan menggunakan densitas arus yang tinggi. Kata kunci: korosi, beton bertulang, produk korosi, retak, densitas arus Abstract Corrosion in reinforced concrete structure can reduce structure performance and its service life due to rebar mass loss. Corrosion amount influenced by corrosion rate can be figured out by using current density. Corrosion amount influences the crack behavior of reinforced concrete, therefore, in this study, experimental study was performed to evaluate the effect of current density to surface concrete cracking behavior of corroded reinforced concrete structure. Accelerated corrosion test tests were conducted with various current density. It was 900 µA/cm2, 500 µA/cm2, 200 µA/cm2 and 100 µA/cm2. NaCl solution was used as electrolyte to produce ion Cl-. The specimens were beam with cross section area 150x150 mm2 and 300 mm in length. Rebar with diameter 19 mm was applied in the center of specimen. The results showed that cracking behavior of corroded rebar has bilinear curve that shows the effect of corrosion products movement through cracks. Furthermore, lower corrosion rate has higher cracking speed than higher corrosion rate. Keywords: corrosion, reinforced concrete, corrosion products, cracking, current density
