Most of Indonesian householder, who is in the low up to middle class, uses kerosene as the main source energy in daily cooking. The objectives of this investigation are to study the effects of glass thickness and slope on the degree of kerosene-stove efficiency. The results of this research could be used as input in designing the characteristic of a glass concave . cover, which can produce the highest efficiency of a kerosene stove. Design used in this research was factorial experimental design. The thickness and shape of the glass concave cover was considerable as the speed of heating process, which showed the degree of efficiency, was considered.as dependent variable. As the control variable, were room temperature, the length of stove's wick, water volume, initial temperature of water, observation range of temperature, type of stove, and the kerosene quantity in the stove tank. Based on the research design, data were analyzed by two-direction variance analysis. With this method, it could be shown whether the thickness and slope and the degree of the stove efficiency will be shown graphically. Base on the result of the data analysis, it can concluded that (1) the slope of the glass concave cover affect the degree of the stove efficiency, (2) The thickness of the cover did not effect the degree of the stove efficiency, (3) at the slope of 82 degree, it was shown that the efficiency was maximum, (4) in comparison to unmodified stove, the modified stove with glass concave cover had an efficiency of 25, 8 % higher at the slope of 82 degree.

This research study uses a mix-method with a sequential explanatory design—data collection using questionnaires and observations from video recordings of work. The research object was 28 students taking CAD courses in the Mechanical Engineering Education Department. The Covid-19 pandemic resulted in data collection being carried out online. The results showed that students’ speed on drawing problems with 2D and 3D modelling according to three levels (easy, medium, and difficult) had differences. The 3D modelling view makes it easy for respondents to do it in a short time and with the right results. If explored more in-depth, the thinking skills that dominate respondents according to their perceptions emphasize creative thinking processes and the ability to solve problems.

This research is an ex post facto research. This study’s population was all XI classes of Fabrication and Metal Manufacturing Engineering, as many as 51 students. The research sample was 44 students based on calculating the 5% error formula by selecting by simple random sampling—collecting data through a test, which consists of 42 questions. The validity test uses the product-moment correlation, and the reliability test uses Alpha Cronbach. Data analysis using descriptive statistical analysis techniques. The results showed that the students’ ability to read orthogonal projection drawings in the very good category was 56.8%, the good category was 11.4%, the moderate category was 20.4%, the bad category was 9.1% b, and the very bad category by 2.3%. In general, the score shows that the VHS state of Seyegan students is in the very good category.
