Abstract

Waste made from plastic, especially plastic sacks has become a national problem because of the intensity of its ever increasing use and the behaviour of the people who are less concerned about the environment, so as soon to find control efforts that are pro-environment, pro-technology and pro-economic. This research aims to analyze the bending strength, modulus of elasticity, and the degree of deflexivity of the lamina composite panels from used plastic sacks as an alternative material which is tough, lightweight, and strong. The research method used was an experimental method with the category of Pre-Experimental Designs type Static Group Comparations. The tests were conducted for the control groups and experimental groups. The experimental group is the group that is treated by varying the orientation of the used woven plastic sack fibers 0°/0°/0°/0°, 0°/+30°/0°/+30°, 0°/+45°/0°/+45°, 0°/+60°/0°/+60° and 0°/+90°/0°/+90°. The control group in this study were specimens that were not treated in the form of bumpers as product controls. The specimens of bending test are using the ASTM D790 standard. The results of the research reveal that the orientation of the fiber affects the bending strength of the lamina composite based on used plastic sacks. The highest bending strength in fiber orientation 0°/+60°/0°/+6°.. is 123.4 N/mm² and the that previous price is 24.96% higher than the bumper bending strength as a product control of 92, 6 N/mm². Debonding occurs on test specimens due to the release of bond in the contact area of the fiber-matrix caused by the shearing forces that the matrix cannot hold.

Abstract

The quality of management in the practical workshop area determines the quality of practical activities in it. Teachers need to prepare a good workshop implementation process by paying attention to everything, starting from the effectiveness of implementation to achieving implementation that provides good habits for students in it. In this case, the thing that is being considered is the implementation of the 5S/5R culture.This research uses Research and Development using the ADDIE development model. The assessment of the suitability of the media being developed is carried out by a judgment expert. The product trial was carried out at SMK Negeri 2 Salatiga with 36 students in the experimental class. Data collection from experts uses material and media validation instruments for product suitability, while data collection on application to students uses teacher assessment through observation instruments and checklist data by researchers to test product effectiveness.The results of this research show (1) that the product developed is a module for management of tools and materials for Vocational High School concrete workshops; (2) The product is declared valid and reliable using the Aiken v test and expert percentage. (3) the module was developed practically based on responses from Experts/Validators consisting of lecturers and teachers practicing Construction and Housing Engineering (4) effectiveness testing using the N Gain test showed that the data for the experimental and control classes had increased with a percentage of 47.59%.

Abstract

The development of technology in education helped to increase learning quality. Existing developments required the world of education to adapt. Students' characterization in the XXI century was a generation that was closed to digitalization, so the teacher had to understand that learning media at school must carry out advanced technology. Specifically, the research purpose was: to develop media with adobe flash, to dig up the feasibility of learning media in the competency of an anti-lock brake system, and to know the improvement of learning outcomes in an anti-lock brake system. This research applied the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The data analysis consisted of determining the feasibility of learning media and deciding the media effectiveness. The feasibility test showed that the media was very feasible. The developed media was tested by N-Gain and got the effectivity until 76%, or it can be declared effective since t-count 18.13t-table, and Ha was accepted while H0 was refused. It can be concluded that adobe flash media with android-based can improve students' learning outcomes, especially in the Anti-Lock Brake Sistem at XII TKRO 1.

Abstract

Steam boilers fueled by biodiesel and coal are one of the industrial activities that still produce exhaust emissions such as Total Particulate (PM), Sulfur Dioxide (SO2), Opacity, Nitrogen Oxide (NOx), and Carbon Monoxide (CO) which is very dangerous for public health and the environment. Therefore, analysis of flue gas emissions in steam boiler installations equipped with filtration devices (cyclones, water scrubbers, and electrostatic precipitators) before being discharged into the environment is of important. Exhaust gas emission was measured by using a gas analyzer, smoke tester, and portable quality air monitor. The results of exhaust gas emission analysis showed that the average concentration of PM, SO2, and CO did not meet the specified emission quality standard thresholds, exempted for opacity concentration for both steam boilers fueled with biodiesel and coal. It is suspected that this is caused by the sub optimal performance of the filtration equipment used in this system. Therefore, regular maintenance is required, and if necessary, a redesign of the entire system can be carried out.

Abstract

Hydroxyapatite (HAp) is a biomaterial containing calcium phosphate with the chemical formula which is similar to the structure of human bone, so it is good for the purpose of healing human bones and teeth. HAp synthesis has several methods that can affect the results of HAp synthesis, such as the method of mixing CaO with phosphate, namely mixing with ultrasonic machines and magnetic stirrers. However, the discussion about the difference of HAp results with the mixing method of ultrasonic machine and magnetic stirrer is still rarely done. Therefore, it is important to examine and compare the characteristics of HAp synthesized by ultrasonic and magnetic stirrer mixing. The result of XRD test shows that HA1 has a purity of weight percentage (wt.%) of HAp crystal of 99.8%, while HA2 has a weight percentage (wt.%) of HAp crystal of 97.7%. For the FTIR test results of both specimens detected the presence of phosphate groups, and hydoxide, where both are the basic form of hydroxyapatite. Carbonate groups were also detected in the test, but it cannot be said to be bad because carbonate is a natural substitute for phosphate.
