Abstract

Welding is one of the joining technologies that has experienced significant developments from time to time, both from the type of welding equipment to the joining method used. This study aims to determine the effect of the large angle of V on Von Mises stress material in the welding process based on the finite element method. The tool used to model Equivalent von misses stress and Equivalent Elastic Strain with the help of finite element method software, the material used is AISI 4130. From the simulation results, it shows that the largest Equivalent von misses stress is found at the 45° V seam angle, which is 1.7251x108 Pa, while the lowest equivalent von misses stress is found at the angle of V 60°, which is 1.7162x108 Pa. As for the Equivalent Elastic Strain, the largest is found at the large V 30° joint angle, which is 0.00129 m or 1.29 mm, while the lowest strain value is found at the 45° joint angle of 0.0011564 m or 1.15 mm. Keywords: Equivalent von misses stress, Equivalent elastic Strain, Large angle of V, Finite element method

Abstract

In the modern era at this time, almost all human beings in all corners of the world have been dependent on the existence of electrical energy or it can be said that almost all the activities of a human being always have a relationship with electricity. This experimental study uses 2 methods of approach, namely initial energy audits and detailed energy audits. The tools used in this, the level of activity of Kendari City Land Office employees. The results of this study indicate that the initial energy audit at the Kendari City Land Office was 186, 9834 kWh / m2 (for 1 year), this has not exceeded the ASEAN-USAID standard on an office which is 240 kWh / m2 year while a detailed energy audit, the kWh value read at the Kendari City Land Office is 34.903,125 kWh (for 1 year). The opportunity to save energy (PHE) in energy audit research is to use lighting that is in accordance with its designation, perform cleaning on each AC unit which includes cleaning the air filter, fan blades, fins, evaporator and output grid on the AC. The recommendation for PHE is to do cleaning every 3-4 months for each AC unit and optimize the use of cloth curtains for each room at the Kendari City Land Office.Keywords : Initial Energy Audit, Detailed Energy Audit, Energy Consumption Intensity.

Abstract

Abstract: Based on the results of the initial survey conducted, it was noted that the total number of nurses working at the Makassar Hajj Hospital reached 316 people. Although the number of nurses is quite large, there are several problems that affect their performance at the hospital. One of the main problems found was the lack of motivation provided by the hospital management. Support and encouragement from the leadership is needed to improve nurses' morale, but this is still not given enough attention. The purpose of the study was to determine the factors that affect nurses' performance. The research design used in this study was cross sectional. The research was conducted at Hajj Hospital Makassar. The research was conducted in April 2022. The study population was all nurses who were in the wards of the Makassar Hajj Hospital. The research sample amounted to 36 people. The sampling technique used Simple random sampling. Data analysis was performed univariate and bivariate. The results showed there was a relationship between work motivation and nurse performance (p value: 0.001) and there was no relationship between leadership style and nurse performance. It is recommended for hospitals to improve the performance of nurses by carrying out supervision and to nurses in the form of monitoring and evaluation of every activity of providing nursing care to patients and providing opportunities for nurses to attend nursing training so that the quality of nursing services becomes better.Keywords: Performance, Motivation, Nurses.

Abstract

This research is a quantitative research type of pre-experimental research with a pre-experimental research desaign in the form of a one-group pretest-posttest desaign which aims to determinate whether or not there is a significant effect of using the Canva-assisted Project Based Learning on the learning outcomes of IPAS class IV students of SD Inpres 5/81 Lemoape. This variables in this study are the Canva-assisted PjBL (independent variable) and IPAS learning outcomes (dependent variable). The population in this study were all students of SD Inpres 5/81 Lemoape as many as 190 students with a sampel as many as 20 students selected based on a cluster random sampling. The data collection technique used was a test to determine students IPAS learning outcomes before and after using the Canva-assisted PjBL. Based on the result of descriptive statistical analysis, the pretest average was 49,25 and the posttest average was 75,25. Meanwhile, based on the results of the normality test analysis, it shows that the posttest date are normally distributed, and the homogeneity test results show that the pretest and posttest date are homogeneous. The result of the hypothesis test show that there is a significant difference in students IPAS learning outcomes before and after using the Canva-assisted PjBL learning model. So it can be concluded that the Canva-assisted PjBL learning model influences the IPAS learning outcomes of students in class IV of SD Inpres 5/81 Lemoape.

The population in the study is all grade V students using a sampling technique, namely a saturated sample of 36 students. The data collection technique was carried out using a questionnaire. The questionnaire used has gone through validity and reliability tests. The validity test used the SPSS version 25 program using a = 5% = 0.05 significance level and the r-valueof the table was 0.5324, while the reliability testing method used was to see the value of Cronbach's Alpha, namely the results of the self-efficacy test were at a value of 0.775 and the motivation to learn mathematics was at a value of 0.821. The data analysis techniques used are descriptive statistical analysis and inferential statistical analysis. Based on the results of descriptive statistics, it was shown that self-efficacy obtained an average of 64.33 in the medium category and the motivation to learn mathematics obtained an average of 61.97 in the medium category. Based on the results of infernal statistical analysis, it shows that the rcalculation > rtable (0.655 > 0.3291) is at a significance level of 5%. Thus H1 is accepted and H0 is rejected. From the results of the study, it can be concluded that there is a significant relationship between self-efficacy and motivation to learn mathematics of grade V students of SD Inpres 5/81 Lemoape, Palakka District, Bone Regency which is categorized as strong in the interval of 0.60 – 0.799.
