“…Health and safety summary statistics in Great Britain 2021 stated that Industries with higher than average rates of musculoskeletal disorders 2018/19 -2020/21is construction, nearly achieved 2,000 cases per 100,000. The previous study showed that the steelwork was done in an awkward working posture (squatting, bending, twisting repeatedly) with a high risk of MSDs (Rula score: 7) and needs curative action immediately (Sudiajeng et al, 2018). Based on the results of this study, and as a follow-up research, ergonomics innovation has been conducted to improve working conditions that lead to the decrease of MSDs risk and improve the productivity of the workers in steel-work for reinforced concrete beams.…”

The digitalization of construction has been carried out to meet the demands of the industrial era 4.0. However, there is still a lot of construction work that is preform manually, such as the steel-bar assembly for reinforcement concrete beams. Based on the 2019 ILO report, it can be seen that fatal work-related illnesses reached 86%, much higher than work accidents, which was 14%. Of the various fatal illnesses due to work, MSDs requires the highest health compensation costs, which reach 40%. The previous study showed that the steel-bar assembly was done in awkward working posture (squatting, bending, twisting repeatedly) with high risk of MSDs (Rula score: 7) and needs improvement immediately. This research was conducted through experiment with pre-posttest control group design. The specific target of this research is to reduce the MSDs risk and increase the productivity by supporting the workers with the ergonomic tetrapod as the working table. The subjects were two groups of students at Civil Engineering Department Politeknik Negeri Bali, with 14 students in each group.

“…Reinforcing steel is expensive and characterized by a large carbon footprint [ 14 ]. The very process of reinforcement preparation, consisting of steel bars, stirrups, meshes and other smaller elements, is prone to human errors [ 15 ]. In the authors’ opinion, 3D printing in civil engineering should be primarily harnessed for the creation of reinforcement.…”

In their fourth decade of development, additive manufacturing technologies are slowly entering research programs dedicated to building materials. While the majority of research effort is focused on using 3D printing of concrete, the authors propose using the technology for creation of spatial plastic reinforcement. Obviously, the strength properties of a 3D printed polymer are much lower than those of steel. Nevertheless, the unconventional spatial shape of a 3D printed reinforcement can substitute for much of the lower mechanical performance of polymer. Flexural characteristics of a cement mortar prism specimen reinforced by hexagon spatial elements were tested and analyzed in this paper. The hexagonal geometric shape was chosen due to its high rigidness. It was proven that it is possible to efficiently reinforce concrete beams by spatial 3D printed polymer elements. Directions of needed research were pointed and discussed.

“…Tourism is an important role in Bali economic growth, but on the other side, tourism trips also contribute to external transportation impacts such as delay, queue, traffic accident, parking issue at tourist destination area, and environmental issues as shows by Gronau in Germany [5]. The lack of availability of a safe and comfortable public transportation makes people have their vehicle, at least a motorcycle [6]. This condition has introduced to the rarity of public transportation usage.…”

Trip chain and mode choices take the important role in transportation and tourism planning in tourist destination. This study analyzed the characteristic of individual and tourist trip to design models of trip chain and mode in Bali Island. These models are needed by the government and stakeholders in drafting regulations, innovation technology, marketing strategies, providing infrastructure and managing traffic. Data collection was conducted randomly through an interview-based questionnaire for international tourist to record the daily trips. The significance analysis of independence variables used multinomial regression. The result shows number of variables which significantly impacts trip chain and mode are age, education, number of visits, length of stay, distance, travel time and cost. Modeling used conditional regression. The model of trip chain shows that the increase in travel time and cost will be considered to prefer less on smallest chain or trip chain 2 choices, especially for repeater tourist. The probability is the more repetition visit of tourist in that island, it will be the more number of trip chain chosen. On mode choice based on operator shows that tourists who have performed trip chain 2-4 have the highest probability was Rent-Car, whereas who completed trip chain 5 or more have the highest probability was Rent-Motorcycle. This result indicates trend to transform of mode choice from car becoming motorcycle for the more number of trip chain has been made in similar operator. The more efficient modes needed for more number of trip chain with low cost and long distance.
