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.

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.

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 PPNSâ€™s graduates are 1959 (1418 male, 541 female) and Polmedâ€™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 studentsâ€™ is 3.39 > male studentsâ€™ 3.28. While at Polmed, it is GPA of female studentsâ€™ is 3.27 > male studentsâ€™ 3.14. Total of students is still gender imbalance referring to the graduates data in year 2018 for PPNSâ€™ 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

Perusahaan yang memiliki karyawan yang loyal akan menunjukkan performansi yang lebih baik dan seringkali akan mengakibatkan konsumen yang lebih loyal. Budaya juga memiliki fungsi penting bagi perusahaan. Budaya memberikan orientasi kepada manusia berkenaan dengan bagaimana melakukan tindakan pada situasi tertentu. Seringkali kurangnya perhatian pihak manajemen menyebabkan menurunnya loyalitas karyawan, dan hal ini berantai dimana budaya organisasi mempengaruhi pekerja khususnya dari sisi kesehatan psikologi pekerja, salah satunya dapat diamati dari tensi tekanan darah. Tujuan dari penelitian ini adalah mengidentifikasi faktor-faktor budaya organisasi pada PT. X dan menguji pengaruh faktor-faktor budaya organisasi tersebut terhadap loyalitas karyawan di PT. X. Selain itu juga menghubungkan antara budaya organisasi dengan hasil pemeriksaan tekanan darah dari pekerja, serta hubungan antara tingkat loyalitas karyawan dengan hasil pemeriksaan kesehatan. Dengan menggunakan analisis faktor diperoleh faktor-faktor pembentuk budaya organisasi di PT. X dan analisis multiple regression untuk menguji pengaruh budaya organisasi terhadap loyalitas karyawan. Hasil dari penelitian ini menunjukkan bahwa faktor-faktor budaya organisasi pada PT. X adalah orientasi pada konsumen, kepemimpinan, harmoni, job challenge, pengakuan kepada karyawan, orientasi pada pekerjaan, orientasi pada orang, kreativitas, tanggungjawab terhadap masyarakat, pengembangan karyawan, social cohesion dan team building. Dari hasil uji dapat diketahui bahwa p=0,109 (p0,05) maka dapat disimpulkan bahwa tidak ada hubungan yang signifikan antara kenaikan tekanan darah dengan budaya organisasi. Sedangkan berdasarkan uji regresi logistik mempengaruhi kenaikan tekanan darah p=0,039 (p0,05) hal ini menunjukkan faktor loyalitas memiliki pengaruh pada peningkatan tekanan darah.

Many obstacles that affect the completion of the project late, like: weather, late general plan approval, late material arrival, less skills and others. The Precedence Diagram Method is the method used to create network planning especially project scheduling. This research will examine how to plan the proper project scheduling of Pressure Vessel project of PT Wika Technip which is done by PT. Barata Indonesia by using PDM.The results obtained from the cost calculation at 252 days of project life have total project cost of Rp.6.131.093.885,00 and at project age 243 days total project cost is Rp.6.236.994.056,00. In this case it is known that there is an increase in total cost of Rp.105.900.171,00 and the time difference of 9 days when the acceleration is done on the project duration from 252 days to 243 days.

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.

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.
