Abstract

The West Sumatra earthquake on September 30, 2009, has left a long sorrow for the families of the victims. The number of children who died at “Bimbel” center at that time was a proof of how vulnerable and at-risk children were to the threat of earthquakes. Learning from the past earthquakes, the local government and policy makers of West Sumatra Province have taken steps to take preventive measures, especially since the 2009 earthquake. Follow-up efforts such as reconstruction and rehabilitation have also been carried out well. However, these efforts will be meaningless if they are carried out sporadically and unsustainably. Efforts that have been carried out and have developed so far must be carried out from upstream to downstream in a more focused manner, starting from children to adults. Community capacity building, both through systematic socialization and sustainable disaster education, must continue to be carried out in every condition where there is no potential disaster in a disaster-prone area. The Law of the Republic of Indonesia No. 24 of 2007 concerning disasters, it is states that one of the groups of people who are vulnerable to disasters is the age group of children. Earthquake disaster education and knowledge need to be introduced early on. This study aims at evaluating the importance of literacy and disaster education for children. The method used is an evaluation method and a review of several previous studies, then summarize the results obtained from some of the previous studies. The results of the study stated that disaster literacy for children is important to do from an early age, so that they have more readiness and capacity to face disasters in the future. Keywords: Disaster Literacy, Disaster Education, Earthquake.

Abstract

One of the concrete technologies developed to obtain good compressive strength of concrete is additional material for iron lathe waste obtained from the residue of the iron turning process. This study aims to determine the effect of iron lathe waste as a fine aggregate additive on the compressive strength of concrete. The compressive strength test of concrete was carried out based on The SNI standard 1974:2011. The sample making of the specimens was carried out by varying 0%, 1.5% and 2.5% of iron lathe waste from the weight of fine aggregate in a concrete mixture with a concrete compressive strength of 29.05 MPa. Concrete samples were tested at the age of 7 days, 14 days, and 21 days. The test results show that the maximum compressive strength of concrete is achieved by normal concrete (0%) which is 28.96 MPa at the age of 21 days of concrete. While the value of the compressive strength of concrete after being given a mixture of iron lathe waste decreased. The optimum concrete compressive strength with the addition of iron lathe waste was obtained at 24.63 MPa with a mixture of 1.5% at the age of 21 days of concrete. The decrease in the compressive strength of concrete due to the addition of iron lathe waste. It occurs because of the air trapped in the concrete, causing the concrete to be hollow and not solid, so that the compressive strength of the concrete decreases. Keywords: Fine aggregate, Strength of concrete, Waste iron, Concrete technology.
