Abstract

Accidents can occur anytime and anywhere such as accidents that occur at work at height. This study aims to identify and analyze potential hazards in the install and dismantle scaffolding work using TRA (Task Risk Assessment) method. The results of the risk assessment using TRA on this work obtained four job description with 2 jobs at low risk, namely initial risk of 4 and after controlling for residual risk of 2. For install and dismantle scaffolding show that medium risk was obtained with an initial risk of 12 and after controlling, the residual risk becomes 9.

Abstract

Determination of hazard identification and risk assessment on the company can not be separated from the calculation of the cost budget. The aim is to provide recommendations and calculate the profit rate using the Benefit Cost Analysis (BCA) method so that the company will more easily determine the most appropriate and needed alternative in the company. From the incremental analysis calculation, an alternative solution and value obtained from BCA are gas detector H2S B / C ratio 1.14, crane certification B / C ratio 3.66, welding helmet B / C ratio value 5.53, wire rope B / C ratio value of 5.19, O2 detector value of B / C ratio 6.11, small handtruck value of B / C ratio 18.1, fire dry chemical powder B / C ratio value of 22.27, N2 gas detector value of ratio B / C 1.53.

Abstract

Industry revolution 4.0 era provides opportunities as well as threats for the students and alumni graduated from vocational education. Man roles are gradually taken by automatic machines. Consequently, unemployment is increasing. This certainly will contribute to the either local or national problems. Therefore, vocational education students have to intensify their learning achievements. This study discusses the learning achievements of the male and female students at the Shipbuiding Institute of Polytechnic Surabaya (PPNS) and Medan State Polytechnic (Polmed). The analysis of learning achievements in this study used the documentation data of the GPA in scale 4, taking the whole population either male (M) or female (F) in the academic year 2015/2016, 2016/2017, and 2017/2018. In the last three years, total PPNS’s graduates are 1959 (1418 male, 541 female) and Polmed’s are 5938 (2821 male, 3117 female). Based on the descriptive quantitative analysis, the average of learning achievements at PPNS shows that accumulated GPA of the female students’ is 3.39 > male students’ 3.28. While at Polmed, it is GPA of female students’ is 3.27 > male students’ 3.14. Total of students is still gender imbalance referring to the graduates data in year 2018 for PPNS’ Welding Study Program in which having only two female students with average GPA 3.41 and 53 students with average GPA 3.15, meanwhile at Polmed, the total students with largest gap in gender occured at the Mechanical Engineering Study Program with total of male students 240 (average GPA 3.10) and female students only 11 (average GPA 3.20). This result indicates that in these two vocational educational institutions, e.i. PPNS and Polmed, the learning achievement of female students is betterand more competitivable than the other

Abstract

Phosphoric acid production companies have a lot of potential hazards that can lead to work accidents. The preventive actions taken by the company is by establishing an SHE (Safety, Health and Environment) division and appointing a safety representative. Based on the results of the safety patrol record, it turns out that there are still a lot of unsafe actions and unsafe conditions that occur and the value of the frequency rate in 2021 is worth 0.23. This study aims to determine the influence of safety management practices on safety performance mediated by the safety knowledge on 40 safety representatives. The method used to analyze the relationship between variables is PLS-SEM (Partial Least Square – Structural Equation Modeling). The results showed that there was a positive and significant influence between safety management practices on safety performance with a p-value of 0.018. In addition, safety management practices also have a positive and significant impact on safety performance mediated by safety knowledge with a p-value of 0.004 and a VAF value of 49,59%. Recommendations that can be given are in the form of implementing safety training, installing safety signs in the workplace, updating and socializing standard operating procedures for work and implementing safety talk and safety briefing.

Abstract

One of the construction companies got a Pressure Vessel project job. During the process of working on the project, it was delayed from the predetermined date so that the company had to pay a fine of 0.2% every day. So it is necessary to analyze project scheduling in order to get the optimal time and cost of working on this project. The methods used in this research are Time Cost Trade Off (TCTO), Precedence Diagram Method (PDM) and crashing. Acceleration is carried out on all critical paths contained in fabrication activities. This study uses alternatives to accelerate the addition of 50% and 75% labor. The results of this study obtained the optimal time and cost with the alternative of adding 75% labor. The resulting acceleration duration is 75 days faster than the actual duration, with costs incurred of Rp. 161,386,836, -, resulting in a 56% decrease from the actual duration cost of Rp. 286,961,745, -. Analysis of the S-curve found that the accelerated duration can be completed faster than the actual duration because, the curve line on the accelerated duration is more sloping closer to the y-axis indicating greater progress each week.
