Abstract

The construction projects are always faced with the possibility of risk problems. The rapid development in the Denpasar area is in line with the many construction projects, especially buildings such as hotel construction, construction of new school buildings, etc. For construction projects in Denpasar, risk control is necessary. In this regard, it is necessary to research the Analysis of Risk Factors. This study aimed to determine the dominant risk factors causing construction project delays, mitigation and risk ownership of the dominant risk factors. This research used the quantitative descriptive analysis method. The measuring instrument of this study used a questionnaire and interviews with contractor respondents. Based on the results, the dominant risk analysis was labor risk with an average frequency value of 13.70 and 17.13 consequences. The dominant question from the labor risk variable was the low productivity of the workforce due to lack of experience with a frequency percentage of 46.67% who answered rarely and 53.33% who often answered. In comparison, the percentage of consequences was 70.00% answered big and 30.00% answered very largely. Risk response that can be done is to recruit new workers and place them according to their skills. The study's ownership of risk was the contractor due to the contractor's error in employing workers in the field.

Abstract

The purpose of this study was to determine the effect size of the blended learning design on increasing the Mathematical Problem-Solving Ability of polytechnic education students during the covid 19 pandemic. The study was carried out at the Bali State Polytechnic (BSP), using a mastery-experimental approach, with a pre-test post-test design of non-equivalent control. design groups. The subjects are students in the engineering field of BSP in 2020/2021. Samples were taken purposively as many as 10 classes and divided into experimental and control groups. Data were collected using a mathematical ability test developed by the researcher. The level of validity is between 0.31 and 0.89, the reliability is 0.97, the average difficulty level is 0.41 and the discriminatory power index is between 0.25 to 0.75. Data were analyzed using t test, paired t test and N-Gain score. There is a significant difference between the average mathematical problem solving ability of students taught using the blended learning model and being taught using the full e-learning model. The blended learning model is more effective in improving mathematical problem solving abilities than the full e learning model. The effect size is very large on increasing mathematical solving abilities in learning using blended learning. The implication is that the optimal application of the  blended learning design in polytechnic education during the covid 19 pandemic, the learning process becomes more effective and succeeds in improving students' mathematical problem solving abilities. ​
