Abstract

Krueng Pante Baro merupakan satu-satunya sungai sebagai akses bagi masyarakat Desa Pante Baro, Kecamatan Juli dan Desa Darul Aman, Kecamatan Peusangan Selatan untuk melakukan aktivitas. Masyarakat biasanya menyeberangi sungai dengan menggunakan perahu kecil yang ditarik dengan tali. Melalui PT. Beruang Group Center, sebuah jembatan gantung sedang dalam proses pembangunan. Proyek ini telah dimulai dari Desember 2024 dan akan direncanakan selesai pada Oktober 2025. Hingga juli 2025, perkembangan proyek telah mencapai 83%. Untuk memastikan akurasi dan kesesuaian antara rencana dan realisasi di lapangan, penggunaan alat survei dibutuhkan untuk proses monitoring. Total station menjadi alat pengukuran paling tepat untuk memenuhi kebutuhan monitoring terutama dalam memverifikasi elevasi, posisi struktur, dan progres volume pekerjaan. Data koordinat yang telah direkam oleh Total Station akan diproses melalui Software Civil 3D. Selanjutnya, data eksisting yang diperoleh dari Civil 3D akan dicocokkan dengan gambar Detail Engineering Design (DED). Hasil penelitian menunjukkan bahwa adanya deviasi minor pada beberapa titik, terutama pada elevasi timbunan oprit. Namun secara umum, deviasi masih berada dalam batas toleransi teknis. Ketidakteraturan elevasi di beberapa bagian disebabkan karena proyek masih dalam tahap pelaksanaan (on going).

Abstract

The availability of natural coarse aggregate is decreasing due to excessive exploitation and rapid infrastructure growth. Therefore, an alternative artificial coarse aggregate is needed to replace natural aggregate in concrete production. This study aims to compare the compressive strength of concrete using natural coarse aggregate with concrete incorporating artificial coarse aggregate from cement paste (BABs) and artificial coarse aggregate from geopolymer (BABp). BABs aggregate is produced by mixing Portland cement and water, while BABp aggregate is made by combining fly ash with an alkaline activator (NaOH and Na₂SiO₃). Both types of aggregate are molded into cylinders, dried, crushed, and sieved to achieve the appropriate size as coarse aggregate. The compressive strength of concrete with aggregate substitution was tested at 7 and 28 days. At 7 days, concrete with BABp exhibited the highest compressive strength (41.18 MPa), followed by concrete with natural aggregate (38.28 MPa) and BABs (36.23 MPa). At 28 days, concrete with natural aggregate had the highest compressive strength (51.65 MPa), but concrete with BABp showed nearly equivalent results (51.51 MPa), while concrete with BABs maintained the lowest compressive strength (45.88 MPa).

Abstract

Indonesia has 650 million tons of Buton Rock Asphalt (Asbuton) deposits.  The mineral residue, known as Asphalt Solid Waste (ASW). The extraction left ASW by 65-90% of asbuton’s weight. However, 770 thousand tons/year of ASW remain underutilized, causing environmental pollution due to its hydrocarbon content. Based on XRD results, Asbuton minerals were dominated with 46% CaCO3, which are potential as a subtitute material in concrete. However, its hydrocarbon content at 68,911 ppm raises concerns. To prevent ASW hydrocarbons from contaminating concrete, solidification was attempted. This study investigates solidification by making Artificial Coarse Aggregate (ACA) products and using ASW as a subtitute for gravel in concrete. The ACAs were produced from a mixture of ASW and cement, molded into 50 x 100 mm cylinders, crushed after twenty eight-days moist curing, and tested according to ASTM C33 standard of gravel. ASW replaced 0-12.5% by volume of sand and ACA replaced 0-12.5% by volume of gravel in concrete with a target compressive strength of 45 MPa at twenty eight-days. Heat of hydration and shrinkage were tested to indentify the impact of CaCO3 from ASW on concrete. The results showed that ACA could reduce 9% of ASW hydrocarbons. However, the ACA produced did not meet the gravel standard in ASTM because ACA absorption reached 6.75% and abrasion test up to 57%. Neverthless, ASW’s high absorption reduced heat hydration by 10% and shrinkage by 83% compared to normal concrete.
