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.
Today shopping online for daily needs has become a culture for some of our society, especially with the Covid-19 pandemic condition that has been going on for a long time, making us to do more activities at home. This has increased the interest in online shopping, especially for women who like to shop, making online stores an alternative to still being able to shop. With conditions like this, many new online shops or online stores that come from these non-online stores have joined in an e-commerce platform. As online stores increase, the competition among online stores are getting tighter and a little bit confusing for consumers to determine which online store to shop for. We need a decision support system that can help assess and compare one store with another. Researchers will use the AHP (Analytic Hierarchy Process) method that works based on a hierarchical structure in determining criteria using the Multi-criteria Decision Making (MCDM) concept that utilizes the results obtained from eigenvectors through iterations to minimize differences in the assessments of a number of respondents. The results will prove that the decision support system for choosing a trustworthy online shop for women's bags is appropriate based on the dimensions of online store satisfaction. The results of this study will be obtained which online shop for women's bags that are selected or in demand for online shopping transactions. Keywords: Analytical hierarchy process (AHP), e-commerce, eigenvector, decision support system, online shop
The increasing scarcity of filler material creates problems for the construction of highways in Indonesia. This increasingly scarce material requires other innovation to replace filler that fulfill the quality standard. One of the filler materials that can be used in asphalt mixture are coal fly ash and clam shells. Currently, the utilization of this waste is still rarely used optimally and only becomes impact of environmental pollution. The purpose of this research is to determine the effect of Marshall characteristic resulting from the using of coal fly ash fillers and clam shells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
