Analisis Karakteristik Campuran Aspal Beton Menggunakan Cangkang Lokan Dan Abu Sabut Kelapa Sebagai Pengganti Filler

Abstract

Along the coast of West Aceh, there are many coconut plantations. Up to the present, people use coconut only as copra, coconut oil and as a drink, while coco fiber is rarely used for other purposes. In addition, resources of the materials are plenti considering the extensive beach length along the west coast of Aceh. Furthermore, there are also long rivers and swamps which can also be a source of community economic income from conch cultivation. Loans are consumed a lot for food, whereas clamp shells are still not optimally utilized. Researchers are trying to utilize this clamp shell as a filler for asphalt mixture. This study aims to determine the characteristics of asphalt concrete mix using lokan shell ash and coconut coir ash as a filler. The method used is Road Construction of Public Works Deparment (Bina marga), by making two scenarios of laboratory experiments. The first test with a variation of cement and shell ash 20: 80% and 50: 50%. The second test is the variation of cement and coconut fiber ash with a ratio of 60: 40% and 50: 50%. The optimum bitumen content obtained from testing variation 1 is 4.1% and 4.9%. From variation 2, the optimum asphalt content is 4,8% and 4,4%. The use of the variation of cement filler and shell ash ash is found to have a higher stability value compared to the use of coconut fiber. This research reveals that the use of variations of filler ash shell can be said to be better if used in heavy traffic.

Strategi Penanganan Lubang Jalan Menggunakan PVC Dan Abu Sekam Padi Sebagai Penerapan Inovasi Teknologi

“…Abu sekam padi memiliki kandungan silicon dioxide (SiO2) yang cukup tinggi (Akbar, Teknik, & Universitas, 2012). Hasil riset awal peneliti (Veranita, 2018), telah menggunakan campuran filler abu sekam padi pada campuran aspal beton. Bahwa abu sekam padi ini bersifat lebih lunak dan menghasilkan campuran aspal yang tidak terlalu kaku dan lebih lentur.…”

Characteristics of Concrete With Red Sand Mixture 80 Mesh Grain Size After Combustion

“…Coarse aggregate is gravel as a result of natural decomposition of stone or in the form of crushed stone obtained from the stone crushing industry and has a grain size between 5 mm -40 mm. The aggregate is called coarse aggregate if the grain size exceeds 4.75 mm (Pagut et al, 2017). The purpose of concrete mix planning is to determine the proportion of cement, fine aggregate, coarse aggregate, water, and additives used must meet the following requirements: 1) A certain elasticity that allows the concrete mix to be placed in the mold/formwork (workability) and the smoothness of the face (finish ability) of wet concrete, which is determined from: a.…”
