The quality of teacher learning practices currently continues to be improved through various training programs, mentoring, and evaluations from Indonesian government support. The 21st-century teacher's ability to develop learning technology is a cooperative learning approach and multidisciplinary integration of science to solve surrounding problems. This study describes the effectiveness and benefits of Science, Technology, Engineering, and Mathematics (STEM) in the Automotive Engineering Competency with the Engineering Design Process (EDP) approach in the "motorcycle burglary case studies." This research is a type of pre-experimental design in the form of a pretest-posttest group design. The purposive sampling technique was carried out to find out the sample of students in one of the vocational schools Yogyakarta, Indonesia in 2019. The results showed that (1) the assessment of lesson plan in the form of review and supervision was declared complete; (2) aspects of the STEM-EDP assessment consist of formative tests, the 1st Student Worksheet, the 2nd Student Worksheet, and Products which stated in the seven stages of EDP; (3) Wilcoxon test, Z = -4.86 with significance (p) = 0.00 <0.05, illustrates that STEM-EDP is effective than summative learning, and can improve learning.

The National Nuclear Energy Agency (BATAN) Yogyakarta uses two kinds of paraffin for shielding radiation of Kartini reactor. For developing BNCT research, the radiation attenuation capability of paraffin has been analyzed to find out the coefficient attenuation, density, and composition of both kinds of paraffin. The components of the paraffin were analyzed using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) spectroscopy characterization. Paraffin P1 has a density of 0.689 gr/mL and paraffin P2 is 0.578 gr/mL. Paraffin samples P1 and P2 were the sample content of functional group CH, CH2, and OH when analyzed by FTIR. Paraffin P2 had an additional content namely CO. The concentration of carbon (C) and oxide (O) of paraffin P2 was much greater than that of paraffin P1. Hydrogen (H) in the paraffin has the function of moderating neutrons, but hydrogen content in both kinds of paraffin could not be detected by EDX. The acquired neutron coefficient attenuation of paraffin P2 was 0.0382 cm-1 and the gamma coefficient attenuation was 0.0535 cm-1.

The research aims to develop learning media on fuel motor lesson concerning the aspects of media, material and media design. It is conducted in mechanical engineering education study program of State University of Gorontalo with the method and development of ADDIE model adopted from Lee and Owens. The research stage consists of analysis, design, development and implementation and evaluation. The development of learning media is carried out only to the stage of development and implementation. It shows that the product of interactive multimedia-based learning media on fuel motor lesson is feasible to be applied, it is based on the expert validation with the percentage of 85% (media design expert), 75% (media expert), and 87% (material expert). The average of all aspects achieved is 82.333% (very feasible)

This study entitled The Effect of Discipline and Workload on Employee Performance with Mediation of Motivation on Employees of the Administrative Bureau of the Regional Secretariat of South Kalimantan Province aims to determine the description of discipline, workload, motivation, and performance and to examine the effect of discipline and workload on employee performance mediated with employee motivation. This study uses a quantitative research sample of as many as 30 respondents—data collection using questionnaires and documentation. In comparison, data analysis uses path analysis assisted by SmartPLS 3 software. The results of this study indicate that the work discipline variable (X1) has no effect on employee performance, workload variable (X2) affects employee performance (Y), work discipline variable (X1) does not affect motivation (Z), workload (X2 ) affect work motivation (Z), work motivation (Z) affect employee performance (Y), work discipline (X1) does not affect performance (Y) with the mediation of work motivation (Z), workload (X2) affects performance ( Y ) with work motivation mediation (Z).

A crucible furnace is developed continuously to obtain appropriate furnace in support casting practice at VHS. This research aimed at improving performance of compact crucible furnace by modification the heating chamber. Fins were placed at inner side of compact crucible furnace wall. The furnace performance determined by increasing of temperature rate to melt 3 kg of aluminium. Descriptive analysis is used to describe performance of modified compact crucible furnace. The fins addition on the inside wall improves the compact crucible furnace performance. The temperature rate is increase as the fins inclination angle increase. Fins with inclination angle of 800 could keep and maintain the temperature of heating chamber. Compact crucible furnace which added fin on the inside wall is able to melt 3 kg of aluminium in 35 minutes.
