Abstract

Ketersediaan air bersih adalah suatu kebutuhan yang sangat penting, terutama di daerah yang belum memiliki akses jaringan Perusahaan Daerah Air Minum (PDAM) seperti Masjid Baitussalam di Kelurahan Sungai Parit, Kabupaten Penajam Paser Utara. Masjid ini selama ini hanya bergantung pada air hujan dan air tanah tanpa adanya sistem penyaringan yang cukup. Kegiatan ini bertujuan untuk meningkatkan sistem Rainwater Harvesting dengan menambahkan sistem penyaringan sederhana memakai media pasir Malang. Hasil pengujian menunjukkan bahwa air hujan sebelum disaring memiliki pH 6,3 dan Total Dissolved Solids (TDS) 627 ppm, yang tidak sesuai dengan standar air bersih. Setelah proses filtrasi, pH naik menjadi 7,0 dan TDS turun secara signifikan menjadi 27 ppm, yang menunjukkan peningkatan kualitas air yang nyata. Sistem ini beroperasi dengan memanfaatkan gravitasi dan tidak memerlukan sumber energi tambahan, sehingga ideal digunakan di komunitas berskala kecil. Selain pemasangan fisik, dilakukan juga penyuluhan kepada masyarakat mengenai cara pemakaian dan pemeliharaan alat filtrasi. Aktivitas ini menunjukkan bahwa sistem penyaringan sederhana yang berbasis pasir Malang dapat menjadi jawaban yang efisien dan berkelanjutan untuk meningkatkan ketersediaan air bersih di kawasan terpencil.

Abstract

This research outlined the results of an experimental investigation of the adoption of refractory brick (RB) as a substitute for coarse aggregate in sustainable concrete production. The concrete mix is produced with two water-cement ratios (w/c) of 0.52 and 0.49, containing 0%, 15%, 30%, and 50% RB as a substitute for virgin coarse aggregate (VCA). The mechanical properties tested in this experiment are compressive strength and indirect tensile strength, as well as the relationship between tensile load and time, the ratio of CO₂ₑ to indirect tensile strength, and acceptance criteria. The test results showed that the compressive strength and indirect tensile strength value decreased along with the increasing percentage of RB adoption as in the concrete mixture. In addition, all phases in the load and time relationships, as well as CO₂ₑ, decrease as the percentage of RB in the concrete mixture increases. The results of the acceptance criteria with the adoption of RB, show that the mixture designed with the adoption of RB variations of 15% and 30% can function as an alternative to VCA. For the acceptance criteria for CO₂ₑ against indirect tensile strength based on the SAI analogy, this research provides a maximum difference limit of 20% to be declared acceptable for use as an alternative to VCA. Thus, the use of 15% and 30% RB instead of VCA is an acceptable and feasible option for sustainable concrete production.
