Abstract

The aims of this research are to find out chemical composition, micro structure, the hardness level, and the strength impact of raw material and after welding using preheating and post weld heat treatment on cast wheel aluminum. Those data were analyzed using comparative descriptive method. The equipments used for measuring the chemical composition, microstructure, the hardness level, and the strength impact are as following: Spectrometer Metal Scan, Olympus Metallurgy Microscope, Vikers Hardness Tester and Charpy Tester. Based on the experiment results, it can be concluded that the chemical composition of the main constituent of cast wheel aluminum is 7,41% Si, which can be categorized in the aluminum alloy AA4343 series. The experiment results showed a decrease in the extent of the microstructure of primary Si phase after welding. Si primary phase were spread well around the surface of 12α"> -Al but the result Si after oxy-acetylene welding process with preheating and PWHT indicates that the primary Si phase is reducing so that the α-Al phase is dominating. The hardness level on the welding result decreased from raw material amounted to 103.381 kgf/mm2 be 40.112 kgf/mm2 in the welding area and 44.378 kgf/mm2 in area Heat Affected Zone (HAZ). The strength impact number on welding area showed a slight increase from the raw material areas of 0.055 joules/mm2to the welding of 0.058 joule/mm2.

Abstract

Urban climate change and rapid urbanization in Medan City have the potential to increase the demand for space-cooling energy, including in primary education facilities. This study examines indications of increasing Cooling Degree Days (CDD) in Medan City based on the NASA POWER satellite meteorological data framework and estimates exposure to cooling-energy loads in elementary school classrooms across 21 districts using official data from the Center for Data and Information Technology (Pusdatin) of the Ministry of Primary and Secondary Education and the Central Statistics Agency (BPS) of Medan City. The approach used is descriptive-quantitative with a hazard-exposure framework, considering that the spatial resolution of NASA POWER data, approximately 0.5° × 0.625° or equivalent to 55–60 km, is coarser than the administrative area of Medan City, which covers 265.10 km². As a result, the spatial variation of CDD is relatively homogeneous at the city level, while exposure variation, represented by the number and density of classrooms, differs significantly among districts. The results show that Medan Marelan District, with 28 elementary schools and an estimated 168 classrooms; Medan Denai, with 24 elementary schools and 144 classrooms; as well as Medan Belawan, Medan Deli, and Medan Labuhan, each with 21 elementary schools and 126 classrooms, have the highest exposure to cooling-energy loads if the citywide CDD trend continues to increase. In contrast, Medan Polonia, with 4 elementary schools, and Medan Baru and Medan Barat, each with 5 elementary schools, have the lowest exposure. This study recommends the integration of higher-resolution data, such as BMKG station data or finer-resolution satellite imagery, in future research, as well as prioritizing cooling-energy efficiency interventions in districts with the highest classroom density.
