The article discusses driver optimization design issues that combine the evolution of artificial intelligence of the bat optimization algorithm with fuzzy drivers to enable practical applications in construction. The designation of system controllers includes various subsections such as initial system parameters, EB optimization algorithm, cloud controllers, stability analysis, and excitation sensors. The advantage of this design is the integrated H2 / H output of a robust strategy for certain systems with continuous and polyhedral uncertainties f or. The asymptote was obtained by adjusting the design parameters with the help of correction criteria. Numerical verification of the time and frequency domain shows the new system design to accurately predict and control the structural displacement reactions required to actively control each model structure . The Genetic Algorithm Test technique uses the Hurwitz Matrix Functional Structure hierarchy for hierarchical conditions and measures of exacerbation of effect. This article proposes any type of dynamic controller to obtain the optimal power structure required for active control of nonlinear structures. This method has shown favorable results in the resolutions of closed systems.

PT Semen Gresik is a company that produces cement with various units, one of which is a production plan and control unit whose job is to plan and evaluate work processes. The problem that exists in the production plan and control office space is the intensity of the lighting in the office space is not under the SNI Lighting standard. 16-7062 2004 for an office space of 350 lux. This can cause eye fatigue which can affect the condition of employees at work. Measurement of eye fatigue using the Visual Fatigue Index (VFI) questionnaire. The subjects of this study were all employees of the production plan and control work unit of PT Semen Gresik. The results of the measurement of eye fatigue are 4 out of 5 employees who experience eye fatigue, and the results of the calculation of the need for lamps require 8 lamps with 36 watts of power and white/daylight color temperature to achieve room lighting standards.

Technological complexity assessment is one of ways to implement the continuous improvement process. This company is a food ingredient company that assure that their products do indeed meet customer requirements of food safety and quality. This study aims to assess the level of technological sophistication based on food safety aspects using technometric and AHP integration. Technological assessment is carried out on the production process of pregelatinized starch as premium and specialty product and its supporting processes within the company. The technometric approach will assess the level of sophistication of each technology component (technoware, humanware, infoware, and orgaware). And AHP is used to determine the contribution of each technology component. After that, computation of the technology contribution coefficient is done to determine the company’s technology level. The results showed that the highest to lowest value of the contribution of sophistication of each component of technology is orgaware with a sophistication value of 1.064, then infoware with a value of 1.047, followed by humanware 0.868, and lastly is the technoware component which is 0.692. The TCC value of the company is 0.909 which indicates that the company has a highly sophisticated technological with modern technology levels.

Mental workload assessment is essential for the optimal interaction of human system in the manufacturing industry. Manufacturing industry engaged in the construction, maintenance, and fabrication service. Performance of the worker will be lower if the higher workload. In the manufacturing industry are two type of workers that mainly involved in the fabrication process such as operator and welder. In This process was found several defects in the finished good which caused the company to suffer losses. Fatigue due to overtime work for seven days and a high mental workload. The aim of this study was to measure the mental workload in the manufacturing industry. In This study was performed on 10 worker in the operator and welder. Mental workload were assessed using NASA Task Load Index (NASA-TLX) and Fault Tree Analysis (FTA) tools. One operator workers and one of welders belonged to the heavy workload category. Finally, NASA-TLX was significantly higher for operator and welder. High mental workload in the manufacturing industry indicated the defection on mental workload. It is recommended to fixes are evaluating and updating rule work, system work, and existing SOP
