Abstract

Bina Marga has produced many methods to identify the types of road damage. IRI (International Roughness Index) and SDI (Surface Distress Index) are several methods that can be applied routinely to determine road functionality. In this study, primary data was obtained in the form of road damage dimensions such as length, width, depth of damage to obtain SDI and PCI values obtained based on the results of a survey of road conditions along 1.1 km and secondary data in the form of previous literature studies. This study aims to compare the level of road damage based on PCI and SDI methods. Based on the results of the comparison of road damage using the PCI and SDI methods, with a distance of 100 meters, the SDI values in the range of 0 – 95 are obtained. In addition, PCI values are also obtained with a range of 12% - 64%. In general, the condition of the roads on Jalan Fajar Ujung, Simpang Payung Sekaki Camat Office to Jalan Asshofa. In general, the condition of road damage is in the moderate to near bad category, so that in order to maintain the proper use of the road, road repair and maintenance is required.

Abstract

Penggunaan material alternatif berbasis limbah sebagai substitusi semen merupakan salah satu upaya untuk mengurangi dampak lingkungan dari industri konstruksi. Penelitian ini bertujuan untuk mengevaluasi kinerja mekanik dan ketahanan beton dengan substitusi parsial abu cangkang telur (eggshell ash, ESA) serta penambahan silika fume (SF) dalam lingkungan asam sulfat. Beton dirancang dengan variasi substitusi ESA sebesar 0%, 5%, 10%, dan 15% terhadap berat semen, dengan penambahan silika fume tetap sebesar 10%. Benda uji direndam dalam larutan asam sulfat dengan pH sekitar 4 pada umur perendaman tertentu. Parameter yang diuji meliputi kuat tekan, kuat tarik belah, kecepatan rambat gelombang ultrasonik (UPV), dan susut beton. Hasil penelitian menunjukkan bahwa campuran beton dengan substitusi ESA sebesar 5% dan penambahan SF sebesar 10% memberikan kinerja optimum, ditandai dengan peningkatan kuat tekan, kuat tarik belah, dan nilai UPV, serta nilai susut yang lebih rendah dibandingkan dengan beton kontrol dan variasi dengan kadar ESA yang lebih tinggi. Peningkatan kadar ESA di atas 5% cenderung menurunkan ketahanan beton akibat meningkatnya kerentanan terhadap serangan asam. Hasil ini menunjukkan bahwa kombinasi ESA dan silika fume pada kadar optimum berpotensi menghasilkan beton ramah lingkungan dengan ketahanan yang lebih baik pada lingkungan asam sulfat.

Abstract

 Palm Oil Mill Effluent (POME) is an agro-industrial waste characterized by a low pH and high concentrations of organic pollutants, including COD and BOD, making it hazardous to the environment if untreated. This study investigates the application of fly ash-based self-healing hibrid geopolymer concrete as a sustainable material for POME stabilization ponds. The concrete mix included fly ash (75%), PCC (15%), 10% silica fume, NaOH solutions of 10M and 14M, and silicate modulus ratios of 2.5 and 3. Cylindrical concrete specimens measuring 150x210 mm were immersed in POME for 7, 14, and 28 days. Tests included compressive strength, porosity, UPV, and visual inspections. Results revealed that concrete with 14M NaOH, a silicate modulus of 3, and 10% silica fume exhibited optimal compressive strength (12.5 MPa), low porosity (9.2%), and high durability after 28 days of immersion. These findings suggest that hibrid geopolymer concrete can serve as an environmentally friendly alternative to conventional pond linings, enhancing resistance to the aggressive chemical environment of POME. Further research is recommended to explore long-term performance and field applications of this material. Keywords: Geopolymer, Palm Oil Mill Effluent, Silica Fume, Stabilization Pond
