This research aims to explore the challenges and opportunities for achieving operational sustainability of boilers in the context of Industry 4.0, using the Stepwise Weight Assessment Ratio Analysis (SWARA) method. The integration of Industry 4.0 technologies has the potential to revolutionize the way boilers are operated, offering benefits such as improved energy efficiency, reduced emissions, and enhanced safety. However, effective implementation of these technologies requires addressing the associated challenges and opportunities. This study ranks the challenges and opportunities based on expert feedback using the SWARA method, highlighting the most pressing issues and areas for improvement. By the feedback from 15 industrial and academic experts, the results suggest that 'workforce transformation' and 'data management and integration' are the leading challenges, while 'improved energy efficiency' and 'enhanced safety' are the most significant opportunities for achieving operational sustainability of boilers in the context of Industry 4.0. This research can inform and guide the development of policies, strategies, and solutions aimed at improving the sustainability of boilers in a rapidly changing technological landscape, and assist industrial managers in finding strategic management for sustainable boiler operation.

The adoption of lean manufacturing as a method for enhancing productivity that led to the reduction of waste and uniformity of cycle time is the subject of this research. In the fast-paced, dynamic, and ever-changing global economy, many businesses are employing the lean manufacturing approach to remove waste, improve processes, save costs, enhance innovation, and decrease time to market. Lean manufacturing is especially appropriate in Bangladesh because many Bangladeshi private garments manufacturing companies are operating below their actual capacity, or undergo late deliveries, due to problems with their traditional production systems and a lack of skilled personnel. A basic full-sleeve t-shirt sewing line was the focus in the study. Non-value-added activities such as a large number of work-in-process (WIP), unnecessary transportation, and product defects due to poor 5S (Sort, Shine, Set in Order, Sustain, Standardize) and lack of traffic light system (TLS) were observed. Researchers also noticed the indifference of the workers. They used time study, line target, process flow mapping, theoretically machine requirement, and line efficiency to assess conventional line productivity. After implementing lean techniques (5S, line balancing, just-in-time), the standard time was obtained using process flow and cycle time analysis. Thus, non-value-added tasks are reduced, resulting in an improvement in production. They compared the previous production line with the lean-implemented production line and they noticed a lot of changes. Results showed that, after lean implementation, SMV is decreased by 0.9 minutes, production is increased by 1,664 pieces per month, the number of workers is decreased by 2 (two) persons, alter percentages is reduced to 4%, spot quantity is reduced to 1.80%, the rejection rate is reduced to 0.68%, WIP is decreased by 7 (seven) pieces, 69.08% efficiency is achieved. Lean manufacturing brought about great improvements in the sewing sector by establishing a standard minute value, a smooth process flow, and productive operations, which made a significant contribution to the achievement of production targets. In this way, lean manufacturing tools and practices can change the overall scenery of a traditional sewing section of the garment industry. This paper gives the whole feasibility assessment for implementing lean manufacturing in the garment manufacturing process.
采用精益生产作为提高生产力的方法，从而减少浪费和均匀的周期时间是本研究的主题。在快节奏、动态和不断变化的全球经济中，许多企业正在采用精益制造方法来消除浪费、改进流程、节省成本、增强创新和缩短上市时间。精益生产尤其适用于孟加拉国，因为由于传统生产系统的问题和缺乏熟练人员，许多孟加拉国私营服装制造公司的运作低于其实际能力，或延迟交货。一个基本的全袖t恤缝纫线是研究的重点。观察到大量的在制品(WIP)，不必要的运输，以及由于5S (Sort, Shine, Set in Order, Sustain，标准化)不良导致的产品缺陷和缺乏交通灯系统(TLS)等非增值活动。研究人员还注意到工人们的冷漠。他们使用时间研究、生产线目标、工艺流程图、理论上的机器需求和生产线效率来评估传统生产线的生产率。实施精益技术(5S、生产线平衡、准时化)后，通过工艺流程和周期时间分析得到标准时间。因此，减少了非增值任务，从而提高了生产效率。他们将以前的生产线与精益生产线进行了比较，发现了很多变化。结果表明，实施精益生产后，SMV减少0.9分钟，每月产量增加1664件，工人减少2人，变更率减少4%，现货数量减少1.80%，废品率减少0.68%，在制品减少7件，效率达到69.08%。精益生产通过建立标准的分值、流畅的工艺流程和生产操作，为缝纫行业带来了巨大的改善，为实现生产目标做出了重大贡献。通过这种方式，精益生产工具和实践可以改变服装行业传统缝纫部门的整体情况。本文对服装生产过程中实施精益生产进行了整体可行性评价。

Employees are the true determinant of the success or competency of an organization. An adequately trained workforce is important to ensure the workplace has the right and valuable employees. Employees in the education sector need the training to improve their performance as they face limitations or challenges to be creative in completing a task. Despite the increasing effects on the training of organizational employees by organizations, there is still limited literature on human resource development issues in developing countries. The study is focused on the effect of training towards employee performance in a public university in Malaysia. Consequently, all the necessary data were collected from primary sources using questionnaires from 244 respondents. This study employed a quantitative approach and found that induction, technical, and soft skill training positively influence employee performance in the case company. In addition, the study recommended future research in training and development strategies, assisting the employees in understanding the relevance of training towards employee performance, monitoring the performance to ensure employees are on track to achieve the best performance, growing and maintaining the employee’s performance to ensure the organization and personal goal can be achieved.

Pemanfaatan ekonomi daerah dapat dilakukan melalui pemanfaatan sumber daya lokal secara maksimal dimana hal ini dapat dilakukan dengan meningkatkan nilai ekonomi sumber daya lokal yang selama ini belum dimanfaatkan secara optimal. Oleh karena itu, dalam penelitian ini digunakan sumber daya air lokal Papua yang melimpah tetapi tidak dimanfaatkan. Kepala udang saat ini hanya menjadi limbah nelayan dan masyarakat di Sorong dan Papua Barat. Walaupun ada yang menggunakan kepala udang, namun hal ini dilakukan di luar Papua dan hanya sebagai pakan ternak. Kandungan gizi kepala udang sangat tinggi dan baik untuk kesehatan. Oleh karena itu, peneliti akan melakukan penelitian berupa percobaan proses pembuatan bumbu dari kepala udang. Penelitian ini akan menerapkan metode taguchi, dimana peneliti harus membuat simulasi untuk menentukan jumlah percobaan dan level yang harus dilakukan. Pada penelitian ini dilakukan dua proses pengolahan yaitu dengan cara di oven dan dengan cara digoreng. Hasil percobaan yang diuji menggunakan uji organoleptik menunjukkan bahwa percobaan dengan metode digoreng memiliki skor tertinggi pada level 3 dengan skor 565.

In the MSTB T-701D Crude Oil Storage Tank project, good scheduling is needed so that the project can run smoothly during the process. The most frequently used methods in designing project scheduling are the Critical Path Method and the Critical Chain Project Management. This study aims to compare scheduling results between the traditional CPM and the CCPM methods. The project used in this research analysis is the Crude Oil Storage Tank MSTB T-701D project. The Root Square Error Method (RSEM) is used to find the buffer size. In the scheduling analysis, calculations are carried out manually and with the help of Primavera P6 software as validation for calculating the total float, critical path, and project network. Project scheduling using the Critical Path Method (CPM) is known to be completed in 164 days. Whereas for the CCPM, the project can be completed in 140.1 days plus the RSEM buffer calculation method of 5.29 days, and the total scheduling with CCPM produces 145.3 days. This analysis shows that the traditional CPM method has a larger estimated duration than CCPM with an RSEM sizing buffer . Then a suggestion was made to work on the MSTB T-701D Crude Oil Storage Tank project using the CCPM and RCA methods.

PT. XYZ is a manufacturing company that produces various types of resins. One of them is acrylic resin, acrylic resin is the raw material for loading solvent base paints such as those used in the automotive paint manufacturing process. In acrylic resin, defects are usually found such as dirty resin, yellow resin color and rust drum. This study aims to determine the value of the sigma level on acrylic resin products before repair, analyze the factors that cause defects in acrylic resin products and provide suggestions for improvements with the Six Sigma approach. So that defects that occur in acrylic products can be reduced or even eliminated, With a six sigma approach in analyzing and calculating data using the DMAIC concept (define, measure, analyze, improve and control), the total acrylic resin defects in the last six months have an average by 8.94% with a type of gross resin defect of 89.88%, drum rust of 95.80% and yellow resin color of 100.00%. While the average sigma value on acrylic resin before repair was 3.15 with DPMO damage of 81,636 for a million productions. Based on the fishbone diagram, the causes of dirty resin defects, yellow resin color, rust drums are from human factors, materials, machines, methods and the environment. Based on the 5W + 1H method, suggestions can be given to companies in the form of periodic checks on machines, making a schedule for cleaning the production area, holding training or training for employees and carrying out supervision from superiors.

One of them is acrylic resin, acrylic resin is the raw material for loading solvent base paints such as those used in the automotive paint manufacturing process. In acrylic resin, defects are usually found such as dirty resin, yellow resin color and rust drum. This study aims to determine the value of the sigma level on acrylic resin products before repair, analyze the factors that cause defects in acrylic resin products and provide suggestions for improvements with the Six Sigma approach. So that defects that occur in acrylic products can be reduced or even eliminated, With a six sigma approach in analyzing and calculating data using the DMAIC concept (define, measure, analyze, improve and control), the total acrylic resin defects in the last six months have an average by 8.94% with a type of gross resin defect of 89.88%, drum rust of 95.80% and yellow resin color of 100.00%. While the average sigma value on acrylic resin before repair was 3.15 with DPMO damage of 81,636 for a million productions. Based on the fishbone diagram, the causes of dirty resin defects, yellow resin color, rust drums are from human factors, materials, machines, methods and the environment. Based on the 5W + 1H method, suggestions can be given to companies in the form of periodic checks on machines, making a schedule for cleaning the production area, holding training or training for employees and carrying out supervision from superiors.

This study aims to analyze factors influencing the usage of MyTelkomsel application based on Technology Acceptance Model (TAM) theory. Data are collected using offline questionnaires distributed to MyTelkomsel application users in Makassar region and its surrounding areas. Data analysis is performed using multiple linear regression after conducting tests for validity, reliability, and classical assumptions. The results of the F-test indicate that overall, all variables collectively influence the usage variable. The results of the partial t-test show that trust, habit, perceived usefulness, and attitude are proven to be influential factors in the usage of MyTelkomsel application, while perceived ease of use and subjective norm do not have a significant impact. This study obtains an adjusted R-Square of 0.577, indicating that the examined factors can explain approximately 57.7% of the variation in the usage of MyTelkomsel application.
