Abstract

The Earth's average surface temperature has increased immensely, reaching 1.45 +/- 0.12 Celsius in 2023. This is linked to growing carbon emissions from industrial activities, particularly the construction sector. The production of 1 m3 of conventional concrete can emit up to 277.82 kg CO2. Indonesia remains the second-largest asbestos importer, contributing over 100,000 tons annually to the local construction sector in 2023. Most of the waste is unmanaged and causes health concerns. Simultaneously, Bali’s stone carving industry generates approximately 30% basalt stone waste, much of which remains unprocessed and is discarded into rivers or roadside drains. Nationally, Indonesia holds over 1 billion tons of basalt reserves, yet utilization remains low. Addressing these dual environmental issues, this study proposes a sustainable concrete innovation that utilizes 3% asbestos waste as a substitute for cement and 20% basalt waste as a replacement for coarse aggregate. The proposed concrete mix was tested following SNI 03-2847-2002, ASTM C39, and SNI 03-1974-1990. The results show a compressive strength of 44.26 MPa, higher than the required 41.4 MPa for high-strength concrete based on SNI 03-6468-2000. The modified mixture also has a 16.71 percent lower density than normal concrete and a slump value of 157.67 mm, indicating good workability. Furthermore, the mix reduces carbon emissions by 31.273 kg CO2 per m3 and lowers production cost by 43.9 percent, saving IDR 731,401 compared to conventional concrete with similar strength. These innovations show that asbestos and basalt waste can be transformed into low-carbon structural materials, promoting the circular economy while mitigating environmental risks from unmanaged industrial waste.

Abstract

The construction sector in Bali still generates significant environmental waste, including from the tabas stone craft industry, which produces waste equivalent to 30% of the original stone in the form of small pieces and powder. Tabas stone is used as an ornament in traditional Balinese buildings, accounting for 50–80% of the construction material in Bali. This waste is often disposed of in rivers, reducing the wet surface area and polluting the environment. On the other hand, mortar as a binding material in construction accounts for about 30% of total building material use, making the use of environmentally friendly local materials in mortar formulations highly relevant. In 2022, out of 1.02 million tons of waste in Bali, about 70% was organic waste. Most of it came from the construction, agriculture, and handicraft sectors, such as bamboo fiber (BF), coconut fiber (CF), and pineapple leaf fiber (PLF). These materials have high cellulose content, namely bamboo powder at 53.6%, coconut husk at 43.44%, and pineapple leaves at 71.5%, which have the potential to be used as environmentally friendly mortar additives. This study aims to evaluate mortar formulations based on basalt scoria with the addition of these fibers from technical, environmental, and cost-efficiency perspectives. The TOPSIS method from the MCDM approach was used to determine the best formulation based on parameter rankings. The results showed that with the addition of 10% cellulose fibers, the compressive strength obtained was 4.137 MPa for bamboo fibers, 3.224 MPa for coconut husk fibers, and 3.923 MPa for pineapple leaf fibers. The ranking results indicate that while bamboo fiber (BF) shows the highest cost efficiency, the MS-12CCF mixture emerges as the most balanced alternative when considering technical, environmental, and economic aspects.

Abstract

Perencanaan perkerasan jalan yang andal penting untuk menjamin umur rencana dan kinerja struktural, terutama pada ruas jalan dengan volume lalu lintas tinggi seperti pada rencana Jalan Tol Gilimanuk–Mengwi. Penelitian ini memiliki urgensi untuk membandingkan metode desain perkerasan kaku yang mengusung prinsip empiris dan mekanistik empiris terhadap kondisi lapangan di Indonesia, yang memiliki karakteristik iklim tropis dengan curah hujan tinggi serta tanah dasar bervariasi. Penelitian ini bertujuan membandingkan hasil tebal perkerasan kaku dengan metode AASHTO 1993, Pd T–14–2003, dan Manual Desain Perkerasan 2024 (MDP 2024). Metode penelitian dilakukan menggunakan pedoman desain perencanaan pada tebal slab beton, yaitu AASHTO 1993, Pd T–14–2003, dan MDP 2024. Hasil analisis menunjukkan metode AASHTO 1993 menghasilkan tebal slab 30,00 cm dengan nilai W18 sebesar 31.363.966 ESA, menunjukkan efisiensi struktural tinggi. Metode Pd T–14–2003 memperlihatkan hasil analisis kelelahan dan erosi dengan nilai persentase kerusakan di bawah 100%, menandakan desain yang aman secara struktural. Sementara metode MDP 2024 menghasilkan nilai fatigue 0% dan erosi 92,77%, menandakan ketahanan tinggi terhadap beban berulang dan potensi erosi tanah dasar. Kesimpulannya, metode MDP 2024 paling representatif dan adaptif terhadap kondisi lalu lintas serta lingkungan di Indonesia. Penelitian ini berkontribusi dalam memberikan dasar ilmiah untuk pemilihan metode desain perkerasan kaku dalam konsep empiris maupun mekanistik empiris.

Abstract

This study aims to analyze the effect of asphalt heating duration and asphalt mixture aging simulation on the performance of stiffness, creep, and fatigue of road pavements. The research was conducted experimentally, with samples obtained from 30 asphalt core drillings in the field, each subjected to six treatments consisting of V1 (1 hour), V2 (2 hours), V3 (3 hours), V4 (6 hours), V5 (7 hours), and V6 (8 hours), all at a temperature of 155°C. Each variation consisted of five samples tested for asphalt properties, including penetration (SNI 2456:2011), ductility (SNI 2432:2011), viscosity (SNI 7729:2011), softening point (SNI 2434:2011), flash point (SNI 2433:2011), and fire point (SNI 2433:2011). The results showed that asphalt properties varied significantly with heating duration (V1–V6), indicating that longer heating had a clear impact on asphalt characteristics. The penetration values obtained for V1 to V6 were 67.17, 64.6, 62.4, 62.2, 58.75, and 49.5, respectively, while the viscosity values were 211 seconds, 206 seconds, 201 seconds, 198 seconds, 193 seconds, and 190 seconds. The softening points were 41.5°C, 43.5°C, 44.5°C, 45°C, 46°C, and 47°C, while the flash points were 318°C, 325°C, 329°C, 330°C, 332°C, and 335°C. The fire points were 330°C, 332°C, 335°C, 340°C, 345°C, and 350°C. The stability values of the mixture increased with heating duration, reaching 1883.5 kg, 2040.5 kg, 2130.2 kg, 2175.0 kg, 2197.4 kg, and 3254.4 kg. Conversely, the flow values decreased, becoming 3.81 mm, 3.05 mm, 2.79 mm, 2.29 mm, 2.16 mm, and 1.91 mm. The average Marshall quotient values for each heating variation were 494.36 kg/mm, 669.45 kg/mm, 762.41 kg/mm, 951.45 kg/mm, 1017.81 kg/mm, and 1235.91 kg/mm. This study can help optimize asphalt heating duration to improve pavement quality and durability. The findings also have the potential to serve as a basis for refining standards and policies in the design and maintenance of more resilient road infrastructure.
