Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan damar terhadap penetrasi aspal modifikai , dan untuk menemukan seberapa banyak penggunaan damar sebagai material substitusi aspal sehingga memenuhi persyaratan penetrasi  sesuai ketentuan SNI.  Persentase Damar yang digunakan sebagai bahan modifikasi antara 2.5%-10% terhadap berat total  aspal modifikasi dengan interval 2,5%. Jenis damar yang digunkan adalah damar mata kucing dan aspal minyak yang digunakan adalah aspal pen 60/70.  Pengujian penetrasi mengacu pada SNI 06-.2456-199. Alat yang digunakan adalah penetrometer.  Hasil penelitian menunjukan bahwa nilai penertrasi aspal modifikasi pada kadar  damar 2,5%, 5%, 7,5%, dan 10%  secara berturut-turut adalah  65, 64, 63, 52, dan  48. Penggunaan Damar sebagai substitusi Aspal Minyak hingga 5,4% masih dalam rentang persyaratan  spesifikasi yakni 60-70 (dmm). Kata Kunci : Damar, Aspal Pen 60/70, PenetrasiABSTRACT The use of biomaterials as a road construction material is one of the research innovations in supporting sustainable development in the transportation sector. This study aims to analyze the effect of the usage of damar on the penetration of modified asphalt, to find out how much damar which used as an asphalt substitution material that meets the penetration requirements according to the provisions of SNI, and to find the equation model of damar content and penetration relationship. The Damar content used as a modified material is between 0% -10% of the total weight of Modified Asphalt with an interval of 2.5%. The type of Damar used is Cat's Eye Damar, and the Petroleum Asphalt used is Penetration Asphalt - 60/70. The penetration testing uses a penetrometer and refers to SNI 06-.2456-199. The results showed that the penetration value of Modified Asphalt is 65, 64, 63, 52, and 48 mm by correspondings to Damar content of 0%, 2,5%, 5%, 7,5%, and 10%. The use of damar content up to 5,4% as a substitute for Petroleum Asphalt is still within the range of SNI specification requirements, namely 60-70 (0,1 mm). Keywords : Damar, Petroleum Asphalt, Penetration

Abstract

There are some various types of sand used for construction materials in Kendari City and its surroundings. Visually, the difference in the type of sand used can be seen from the color. This study aims to provide information to stakeholders: the community, government and the business, in considering the selection of technically feasible types of sand for concrete mixtures in Kendari City. The sand used in this study was mointain sand ex. Nambo: light brown sand, white sand and maroon sand, as well as river sand ex. Pohara. Physical characteristic testing carried out by the recommendation of SK SNI No. S-04-1989-F which includes sieving analysis, fineness modulus, aggregate material passing sieve No. 200, organic content, bulk density, specific gravity, and water absorption. This study shows that the physical characteristics of mointain sand ex. Nambo: white sand, light brown sand, and maroon sand do not meet the specifications in relation to the amount of sand passing sieve No. 200. Physical characteristics of river sand ex. Poharadoes not meet the specifications which relating to 2 (two) parameters: the amount of material that passes the sieve No. 200 and organic content.For the use of the sand as a normal concrete mixture, it is recommended that the sand be washed first.

Abstract

Soil compaction plays a crucial role in determining the stability of structures, particularly in earthquake-prone regions. Inadequate compaction can lead to soil liquefaction and settlement, increasing the risk of structural failure during seismic events. Understanding the impact of different soil compaction methods is essential for enhancing building resilience. This study aims to evaluate the influence of various soil compaction techniques on the stability of buildings in earthquake-prone areas. It seeks to identify the most effective methods that can improve soil properties and overall structural integrity. A comparative analysis was conducted using laboratory experiments and field tests. Different compaction methods, including static, dynamic, and vibratory compaction, were applied to soil samples. The study measured parameters such as soil density, moisture content, and shear strength to assess the effects of each method on soil stability. The findings reveal that dynamic compaction significantly improves soil density and shear strength compared to static and vibratory methods. Structures built on dynamically compacted soil exhibited greater resilience to seismic forces, demonstrating lower risks of liquefaction and settlement during earthquakes. The research concludes that the choice of soil compaction method is vital for ensuring the stability of buildings in earthquake-prone regions. Dynamic compaction emerges as the most effective technique, providing enhanced soil properties that contribute to structural resilience. Future studies should explore the long-term effects of compaction methods and their implications for building codes and practices in seismic areas.

Abstract

The increasing demand for sustainable construction practices has led to the exploration of recycled materials, particularly in road projects. Recycled concrete not only reduces waste but also offers potential environmental and economic benefits. Understanding its effectiveness in real-world applications is essential for promoting its wider use. This study aims to evaluate the performance of recycled concrete in highway construction projects, assessing its structural integrity, cost-effectiveness, and environmental impact. It seeks to provide insights into the feasibility of using recycled materials in road infrastructure. A case study approach was employed, analyzing three highway projects that utilized recycled concrete. Data were collected through site inspections, material testing, and interviews with project managers. Key performance indicators, such as compressive strength, durability, and cost savings, were evaluated. The findings indicate that recycled concrete performed comparably to traditional concrete in terms of compressive strength and durability. Cost analysis revealed significant savings, with recycled concrete reducing material costs by an average of 15%. Environmental assessments highlighted notable reductions in carbon emissions and landfill waste. The research concludes that recycled concrete is a viable option for highway construction, offering both economic and environmental advantages. The positive outcomes from the case studies support the broader adoption of recycled materials in infrastructure projects. Future studies should focus on long-term performance and the development of guidelines for integrating recycled concrete in various construction applications.
