Abstract

ABSTRAK Pemanfaatan biometerial sebagai bahan konstruksi jalan merupakan salah satu penelitian inovasi dalam mendukung pembangunan berkelanjutan pada sektor transportasi. 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

Agregat quary Moramo merupakan agregat yang banyak digunakan sebagai bahan konstruksi di wilayah Sulawesi Tenggara. Penelitian ini bertujuan menganalisis sifat-sifat agregat sebagai material penyusun beton, perkerasan jalan, dan material fasilitas bandar udara. Penelitian ini mencakup Impact Test, Kualitas Butiran Agregat Kasar, Gumpalan Lempung dan Butiran Mudah Pecah, kekekalan, berat jenis, penyerapan air, dan berat isi. Sampel pengujian berupa agregat hasil pengolahan quarry Moramo yang diterima di Laboratorium Teknik Sipil Universitas Halu Oleo. Hasil penelitian menunjukan bahwa rata-rata abrasi agregat kasar 30.40% (Cara A) dan 31.31% (Cara B), Berat Jenis kering 2.594-2.693, penyerapan air agregat kasar sebesar 0.858-1.243 %, Nilai kehancaran agregat 5,11 %, persentase gumpalan dan butiran mudah pecah dalam agregat 27,20 ton.

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.
