Abstract

One of the air quality conditions in the Special Capital City Region (DKI) Jakarta is the transportation sector. The air quality index is dominated by moderate conditions, even at dangerous levels. The COVID-19 pandemic caused the DKI Jakarta Provincial Government to lock down in March 2020. Research in several countries has shown that air quality has improved because people's mobility has been stopped. This study aims to determine the effect of the lockdown imposed in DKI Jakarta on its air quality and see a comparison at each point. The method used is descriptive method. The data analyzed in this study were collected from 5 points of the Air Quality Monitoring System (AQMS) monitoring tool. Based on the research, it was concluded that the lockdown imposed in DKI Jakarta only affected the location of point 1 at the Hotel Indonesia (HI) roundabout. The Air Pollution Status Index (ISPU) is dominated by good air quality conditions. Other areas such as West Jakarta, East Jakarta, North Jakarta and South Jakarta, the lockdown imposed in March 2020 did not have any effect on increasing the ISPU value. In 2021 the air quality condition in DKI Jakarta is worse than in previous years at all monitoring points since the activities have returned to normal and traffic jams frequently occur. Keywords: Air Quality Index, DKI Jakarta, Lockdown, Transportation.

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

Buton asphalt is a kind of natural asphalt found in Indonesia. The government is recently trying to develop various ways so that the use of Buton asphalt can be optimized to meet the demand for quality asphalt supplies for road pavements. CPHMA is a product from the development of Buton asphalt which has the advantage that it can be spread in conditions of air temperature (known as Cold mix) and elevated temperature (known as Hot mix). In this study, tire powder was used in addition to variations of 0%, 2.5%, 7.5% and 12.5% on CPHMA asphalt with variations in compaction temperature of 30oC, 60oC, 90oC, 120oC, and 150oC. Based on the results of tests carried out, the use of used tire powder from motor vehicle waste can improve the performance of CPHMA with an additional percentage of 2.5% at a compaction temperature of 150oC to meet the specified specifications. Keywords: CPHMA, Tire Powder, Marshall.

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.

Abstract

Mortar is an especially important component used for construction. The building blocks of mortar consist of cement, fine aggregate, and water. In this study, oyster shells were used as a substitute for fine aggregate due to the increasing production of oyster shells every year, with the hope that the use of oyster shells could reduce oyster shells waste in the environment and obtain innovations for the construction world. The test objects were made in the form of a cube using a mixture ratio of 1 PC: 3 PS with variations of 0%, 5%, 10%, and 15% of shells against the weight of sand with a test time of 3 days, 14 days, and 28 days. Before making the test object, the mortar constituent materials were tested first, then the mortar design was carried out after all the constituent materials met the requirements. This study also used SPSS software to determine the effect of using shells as a substitute for fine aggregate on the compressive strength of mortar. From this study, it was found that the effect of oyster shells substitution was 17.6% at the age of 28 days compared to mortar without shells. The use of oyster shells can increase the compressive strength of mortar up to 97.6% at the age of 28 days. A variation of 15% was found at the age of 28 days as a variation with a maximum compressive strength value of 18.06 MPa. Keywords: Compressive Strength, Mortar, Oyster Shells.
