Abstract

Plastics which are classified as inorganic wastes take a long time to decompose. The amount of plastic that is continuously increasing requires serious treatment to avoid its environment problem. It is therefore important to minimize the discharge of waste with reusing and recycling, so that the disposed waste will be fewer. This research aims to find the effect of plastic pellets as a coarse aggregate to the weight-volume, compressive strength, and split tensile strength of concrete compared with normal concrete (crushed stone as the coarse aggregate), and to determine classification based on the weight-volume and compressive strength of concrete. The results of the research showed that the higher levels of plastic pellets in concrete, the lower the weight-volume, compressive strength, and split tensile strength of concrete, where a decline to normal concrete. According to SNI 03-3449-2002, concrete with 60% and 80% pellets levels are not classified as lightweight concrete, whereas concrete with 100% pellets levels are classified as structural lightweight concrete because its weight-volume is less than 1850 kg/m3. The results of compressive strength test showed that concrete with 60%, 80%, and 100% pellets levels are categorized as structural lightweight concrete because its compressive strength is more than 17,3 MPa, whereas according to SNI 03-3449-2002 are categorized as structural lightweight concrete. Keywords: pellet, split tensile strength, lightweight concrete

Abstract

Pemilihan bahan yang digunakan dalam pembuatan jalan menjadi salah satu faktor yang mempengaruhi kualitas jalan, yaitu aspal, agregat dan bahan pengisi (filler). Dalam mendukung pelestarian alam, maka muncul ide untuk memanfaatkan bahan limbah dari aktivitas manusia sebagai bahan pengganti filler yaitu abu bonggol jagung (Frumentum Cobs). Pemanfaatan bonggol jagung diharapkan dapat mengurangi jumlah limbah yang mencemari lingkungan. Tujuan dilakukan penelitian ini agar mengetahui kelayakan bonggol jagung sebagai bahan filler. Serta, mengetahui nilai karakteristik dari penggunaan bonggol jagung sebagai filler dengan variasi 0%, 20%, 40%, dan 60%. Adupun batu pecah yang dipakai berasal dari quarry Bili-Bili dan bonggol jagung diambil di Kabupaten Soppeng. Cara yang dipakai dalam penelitian ini diantaranya analisis laboratorium pengujian agregat, aspal dan filler yang menghasilkan benda uji. Selanjutnya, penggunaan marshall test pada benda uji dilakukan untuk mendapatkan nilai KAO dan subtitusi kelayakan filler bonggol jagung. Adapun, hasil dari pengujian pada benda uji  terhadap karakteristik filler arang bonggol jagung sebagai bahan subtitusi filler diperoleh nilai (KAO) yaitu 5,98. Selain itu, kadar filler arang bonggol jagung yang layak digunakan ialah variasi 20% dengan nilai VIM, VMA, VFB, Stabilitas dan Flow memenuhi spesifikasi bina marga 2018. Hasil penelitian ini diharapkan berguna dalam mengurangi jumlah limbah, serta sebagai referensi penelitian selanjutnya.

Abstract

This study aims to determine the effect of using plastic waste Low Density polyethylene ( LDPE ) on the characteristics of a mixture of AC- WC . This study used five plastic content variation is 1 % , 2 % , 3 % , 4 % , and 5 % to determine the characteristics of the AC- WC . The method used in this study is a test that aims marshall know the characteristics , the performance of the mixture , and the optimum level of use of asphalt in the mix AC- WC . The results showed that the characteristic value AC- WC that include the percentage of plastic content obtained from the testing of 1 % -5 % of the optimum bitumen content , if the levels of plastic in bitumen is added, the value of stability , flow , and marshall quotient increase and decrease unstable , while the value of VFB and the density increases, and the value of VIM and VMA decreases.

Abstract

The top layer of pavement that functions as a wear layer is called AC-WC/ Laston. Improving the quality of flexible pavement continues to be developed in order to create transportation support facilities that are safe, strong and durable, but still economical. The use of additives is one way out that can be done in order to get a high quality product. The purpose of this research is to identify the optimum asphalt content to be used in the manufacture of polystyrene asphalt mixtures and to determine the characteristics of asphalt mixtures using polystyrene additives. The method used was to add polystyrene in the form of styrofoam which had previously been dissolved using gasoline into hot asphalt with a percentage of polystyrene mixture of 3.0%, 3.5%, 4.0%, 4.5% and 5.0% of the optimum asphalt content used. Based on the results of testing specimens with additional polystyrene, VIM and VMA values increased at levels of 3.0% to levels of 4.5% exceeding the upper limit of VIM specifications, but still within specifications. The stability value increased along with the increase of polystyrene from 3.0% to 5.0%, where this value meets the specifications. The flow value increases from 3.0% to 3.45% levels exceeding the upper limit of the specification then decreases after 3.45% levels to 5.0% levels where the flow value meets specifications. The conclusion that can be drawn is that the addition of polystyrene mixture in AC-WC can increase the hardness level of the Laston mixture.
