Abstract

Ship production activities at the Shipyard Company require lifting and transporting aircraft to facilitate work, one of which is a crane. Crane operators work monotonously at the wheel of the crane every day for 8 hours or even more. Concentration is needed in this job. Concentration is a state in which a person focuses his attention on an object within a certain time. Loss of concentration in the operator can lead to mismatches in work and the worst risk is the occurrence of work accidents. This study aims to determine the relationship between mental workload, work stress, and motivation with the level of concentration in crane operators. The population of this study were 35 crane operators. Sampling using total sampling technique with the entire population sampled. Measurements used the NASA-TLX questionnaire to measure mental workload, Stress Diagnosis Survey to measure work stress levels, motivation questionnaire and Grid Concentration Test to measure concentration levels. Data analysis using the chi square test, with the results showing that the independent variables that have a significance value <0.05 are mental workload with a value of 0.009 and work stress with a value of 0.044. While the motivation variable has a significance value of 0.391. The conclusion obtained is that the variables associated with the level of concentration are mental workload and work stress, while the motivation variable has no relationship with the level of concentration.

Abstract

This research discusses the method of making distribution pipes using the Submerged Arc Welding (SAW) welding process, especially for pipes with spiral connections. The material used is API 5L X65. SAW pipes with spiral joints are more commonly used for low-pressure piping systems. However, in certain cases, the production of SAW pipes for Sour Service distribution requires special treatment. Sour Service pipes have a high level of corrosion and residual stress, so Post Weld Heat Treatment (PWHT) is required to prevent Hydrogen Induced Cracking (HIC). HIC occurs due to the absorption and accumulation of hydrogen gas in the metal, causing the formation and growth of cracks, which is also influenced by residual stress. PWHT is applied to reduce residual stress to reduce the risk of corrosion. PWHT is a process to change the structure of the weld metal by heating the metal at a certain temperature and time. This research shows that variations in PWHT temperature produce an average residual stress that is not much different with less difference than 2%, In corrosion testing with the HIC method shows crack evidence but is still satisfactory NACE MR0175 criteria for pipe PWHT temperature variation conditions.

Abstract

Outboard Engine has been known and used as motor boat among of the residents of fisherman community in Tlocors village. Motor boats powered by outboard engine are not only used for fishing, but also used as marine tourism facilities. Considering the vital functional usage of outboard engine for Tlocor’s fisherman community and village community tourism groups  (Pokdarwis), for maintaining    economic livelihood, any interrupted items that happened during motor operation periods would be very significant impact on their daily life. Loss of income resulting from engine problem is the most of many potential cases occurred on the communities.   Hence, it is necessary to provide assistances for both Tlocors Communities, the fishermen, and village community tourism groups. Assistances were also considered part of the public service obligation to communities provided by the Institution.  Training on Outboard Engine Maintenance and Repair would become the scheme of the assistances. This tailor- made assistances would be targeted to both clusters. Better understanding and having a certain competency level on outboard engine maintenance and repair would have a significant value in order to empowering both communities, and become the main purpose of the assistance as well
