MSMEs in Indonesia are expected to be able to face competition in the era of industrial revolution 4.0. However, there are many problems and obstacles in competitiveness, especially facing global competition, including access to capital, access to information and technology, access to organization and management, and access to business networks and partnerships. Besides, it is often difficult for them to get additional capital through banks or other lenders to increase their business scale. Moreover, a lack of financial and digital literacy causes the low validity of MSMEs' data to lenders. The adoption of blockchain technology is one of the considerations to minimize these MSMEs problems. Meanwhile, this technology is still relatively new to be applied to MSMEs but positively impacts the future. This study aims to measure and analyze MSMEs' readiness in using blockchain technology on a business scale with the TRAM model. This model integrates the Technology Readiness Index (TRI) and Technology Acceptance Model (TAM) models. This study aims to test several variables, including TRI, perceive ease of use, perceive ease of usefulness, attitude toward, and intense use of blockchain technology. Data processing uses the partial least square path modelling (PLS-PM) method. The results showed that TRI was significant on perceived ease of usefulness and perceived ease of usefulness. Then, perceive ease of use is significant towards perceive ease of usefulness and intention to use. Besides, perceive ease of usefulness is significant for attitude. The attitude toward variable is significant for the intention to use in the acceptance of blockchain technology.

Lean manufacturing (LM) is established as a best practice to improve the performance of manufacturing industries. Not all the manufacturing industries realize the benefits of LM practices specifically continuous process industries. The present research work is intended to study the advantages of implementing LM practices in an ethical paper industry which is a continuous production industry. Presently, the industry suffers with the problems such as lack of productivity, raw material wastes, underutilized resources, and lack of standard practices in the production. Gemba technique is adapted to record the information related to the present manufacturing environment. Based on the current state analysis, the feasible lean tools are selected and implemented such as 5S, Kaizen, and Total Productive Maintenance (TPM). The improvements have been noted as reduced tool change over time, reduced material wastes, effective utilization of resources and provide safety guidelines to workers and operations. The implications of these improvements increased the productivity also.

This paper presents a continuous improvement (CI) project based on the application of Lean Six Sigma (LSS) methodology. This project was carried out at coffee manufacturing industry located in northern area of Malaysia. The focus of this presented CI project is to improve the weight inconsistency problem of coffee powder packaging. The presented CI project was mainly guided with Six Sigma methodology of Define, Measure, Analyze, Improve and Control (DMAIC) steps, and related Lean tools applications. The step of Define summaries the overall view of CI project. In the step of Measure, current level of sigma based on defect per million of opportunities (DPMO) calculation was determined. Initially, 6% of rejected products were recorded, which it presents the sigma level at 3.1. In the step of Analyze, a series of team-based activities towards root cause identification was carried out. It included the applications of cause effect (CE) analysis and possible causes prioritization and close observations on packaging process. In the step of Improve, the related Lean tool was proposed to improve the problem under study. In the final step of Control, related supportive actions were suggested to sustain the effectiveness of the proposed solution. There are fourteen possible causes are initially identified in CE analysis and based on team’s evaluation process of possible causes prioritization four causes are collectively to be the most possible of root cause(s). Three close observation sessions were carried out to finalize the most possible root cause of the problem. Result strongly suggested that the high variation of coffee powder’s size and inconsistency is the root cause. An improvement strategy based on Lean Manufacturing approach called ‘poka yoke’ is proposed. The proposed improvement strategy was then validated based on real packaging process scenario. Result shows that the proposed improvement strategy is significantly effective to solve the problem with 0% of reject product was recorded so far, where it is not only produced the product within the acceptable weight of 215 and 208 grams, but also presents the reduction of weight fluctuation that close to ideal weight of 208 grams.

One of the company's efforts in implementing the commitment to customer satisfaction is carried out through continuous improvement activities. All indicators are evaluated to determine the level of quality stability against process variations that will impact non-compliance with predetermined product specifications. One of the quality problems found in the tire manufacture industry is the out-percentage of tire uniformity, which suddenly increases, one of which is the value of static balance. This study analyses the process variation factors that occur to take corrective and preventive actions through a series of Root Cause Analysis (RCA), Fault Tree Analysis (FTA), and Failure Mode and Effect Analysis (FMEA). Refers to the analysis result, it was found that there was a problem with the rubber film gauge variation at the manufacturing step of the steel breaker, one of the material components in the tire construction. Two main factors cause rubber film thickness variation: rubber sticky with roll calendar, Radial Run Out (RRO) Roll Calendar out standard, and viscosity compound variation with 12 root problems found. The results of the improvements that have been made can effectively improve rubber film thickness variation, increase the Cpk level of steel breaker material from 0.82 to 1.91 and reduce the out percentage ratio of static balance by 54.65%.

The learning process between students and lecturers usually occurs face-to-face in class. Technological developments and a continuous pandemic change the learning process to be a face-to-face e-learning process. The mental load during face-to-face learning is very different from learning in e-learning. This study was built using ergonomic thinking that is integrated with the use of e-learning. Cognitive ergonomics see from the point of view of students' comfort in cognitive thinking processes when doing e-learning. Data processing and testing will use a questionnaire derived from the NASA-TLX method. The results obtained from this study are the mental load calculations of each NASA TLX calculation. NASA TLX calculations show that efforts with a value of 267.29 dominate students. It could indicate that in e-learning lectures, students need more effort in conducting lectures. In addition, students experience fatigue while participating in online learning. It can be seen from the average SOFI measurement, which is only 1.26.

XYZ company is one of the small-medium enterprises (SME) engaged in the batik industry with the main focus on making muslim clothes made from printed batik and batik. The company cannot evaluate the cause of the turnover decrease because no performance measurement has been applied. Therefore, a company performance measurement is carried out using the performance prism approach because a company performance appraisal is needed stakeholder contributions using the performance prism approach. Stakeholders of this company are consumers, employees, community, capital owners, and suppliers. Supporting the performance prism frame­work, the AHP method was used to determine the weighting and hierarchical structure and then carried out a scoring system with the help of OMAX to determine the company's actual score. This design shows that corporate stakeholders, including owners, consumers, employees, suppliers, and the surrounding community, obtained as many as 34 KPIs. From the implementation of the performance measurement system with OMAX scoring obtained the value of company performance based on satisfaction aspects (6.489), contri­bution aspect (6.582), and capability aspect (5.646). Recommen­dations are also given to improve it.

Children with cerebral palsy at rehabilitation centers had difficulty performing walking rehabilitation with the existing walker. The resulted in children with cerebral palsy feeling dissatisfied with existing walkers, and this dissatisfaction resulted in their interest in ongoing rehabilitation. The existing walker does not accommodate the needs of cerebral palsy children, resulting in lousy form and dissatisfaction when using a walker for rehabilitation and reduce their interest in rehabilitation. Therefore it is necessary to redesign the walker to prevent bad form and increase the satisfaction level of children with cerebral palsy. The QUEST 2.0 questionnaire was used as a reference for designing. Based on the dimensions from the QUEST 2.0 questionnaire, the walker design criteria were determined. Then use the TRIZ method to resolve any technical contradictions that occur at the design stage. Assistive device

Fuel requirements have a direct impact on mining activities. The operator's habits influence the amount of fuel used in operating the equipment, the mine road's slope, and the distance predetermined in the mine design planning. Adjustment Fuel Consumption Actual (AFCA) is the fuel cost, which is influenced by the fuel price, distance, and condition of the mining road billed for overburden and coal mining activities carried out by the contractor. The research methodology uses off-site and on-site analysis. Off-site analysis can be carried out the highest 'Fuel Ratio' owned by the machine based on its specifications and operational activities to find out how much fuel consumption is needed to produce the amount of production per hour (liters/bcm). Meanwhile, it needs to be correlated with the mine road's condition, including the slope of the mine road (grade). This study aims to determine the relationship between road grade and fuel consumption by comparing road grade improvement efforts with cost-benefit analysis.
