Abstract

The object of this research is the Industrial Engineering (IE) study program at Bandung Institute of Technology Cirebon Campus which runs block and non-block system lecture. The block system is a lecture by combining two to three class meeting of a course in one day while non-block system is a one time meeting in a week. Block system faced a lot of complained from students because the class were too hectic, the inability of students to receive a lot of quantitative material, and the monotony of the class. This study evaluates student’s mental workload by comparing the results of experimental measurements while attending block and non-block classes. Mental workload was measured with three measuring instruments, named NASA-TLX, Karolinska Sleepiness Scale (KSS), and Stroop test. Experimental results with 38 students concluded that there is actually no significant difference in mental workload between the two systems. Factors that could cause this results to happen include previous experience in block classes, non-optimal block system instructional learning time, mental fatigue in students, and decreased attention.

Abstract

In the context of industrial development, micro, small, and medium-sized enterprises (MSMEs) are considered flexible in capitalizing on business opportunities and are perceived as more resilient during economic crises. However, intensifying global competition underscores the importance of technology as a determinant of success. MSMEs need to enhance their technological capabilities to improve their business performance, despite frequently facing financial constraints. The government's role in supporting MSMEs becomes crucial through the development of infrastructure and policies that foster the growth of small industries, strengthen competitiveness, and facilitate product exports. The aim of this article is to formulate effective development policies for the technological components and operational policies to support the growth of X MSME. The methodology used involves a review of relevant literature on policies for modern small industries, encompassing small industry development approaches, problem-solving solutions, guiding principles for small industry development policies, the triple helix model, operational policies, continuous strategic improvement, and criteria for small industry development success. The article's findings recommend development policies based on Technoware, Humanware, Inforware, and Orgaware (THIO) aspects to be implemented by X MSME, along with operational policies from the government as a form of support and guidance for MSMEs.

Abstract

To maximize their production, many companies invest their funds into a semi-automatic machine to help them reach their fullest potential. However, many forgot to also take into account the adjustments that have to be done to the preexisting schedule because of the idle time that operators have now that the new machine has arrived. Multi-task simultaneous supervision dual resource constraints (MTSSDRC) have been the go-to method to solve that problem. Nonetheless, there is still an absence in an MTSSDRC field that involves an Unrelated Parallel Machine Scheduling Problem (UPMSP). This research proposed a model of MTSSDRC that is in line with UPMSP where the machine is a complex system and variations of machining speed can happen from a certain machine to certain jobs. This research also brought MTSSDRC closer to its real-life counterpart as a shop floor that exists in many manufacturing industries.

Abstract

Differences in prosthetic leg design and mechanism affect lower limb muscle activity. Unbalanced muscle activity has the potential to reduce the function of physical mobility and change the balance point which has an impact on reducing performance, causing a decrease in the productivity of people with amputation disabilities. This study aims to determine the effect of awkward body posture and type of prosthetic foot on muscle activity in prosthetic foot users. This study used a within subject design with a total of six participants. Independent variables include body posture and type of prosthetic foot. Electromyography signal measurements on the biceps femoris (BF), gactrosnemius (GC), rectus femoris (RF), erector spinae (ES) muscles were performed to evaluate the level of muscle activity. Electromyography signals were processed with a 10-450Hz band-pass filter. ANOVA Repeated Measure obtained the results of awkward posture affecting muscle activity, especially in GC, BF, and ES muscles in the normal leg. In conclusion, the type of prosthetic leg does not affect muscle activity, but body posture has a significant effect on muscle activity although not in all muscles. This study can be used as advice to transfemoral amputation patients to use prosthetic feet that can reduce the risk of WMSDs so as to improve daily performance like normal individuals.

Abstract

Di Indonesia terdapat jenis kaki prostetik yang sudah umum digunakan oleh seseorang yang diamputasi atas lutut, namun masih banyak pengguna yang mengeluhkan nyeri punggung bawah ketika menggunakannya. Penelitian dari Institut Teknologi Bandung (ITB) telah membuat desain kaki prostetik terbaru dengan menambahkan mekanisme brake control pada sendi lututnya yang diduga dapat mengatasi keluhan tersebut terutama ketika melakukan pekerjaan fisik. Namun performa kaki prostetik tersebut belum pernah diuji untuk aktivitas kerja. Tujuan dari penelitian ini adalah menguji pengaruh jenis kaki prostetik dan postur tubuh awal pada saat melakukan aktivitas pengangkatan pemindahan beban terhadap aktivitas otot menggunakan electromyography (EMG). Selain itu, dilakukan pengukuran tingkat ketidaknyamanan yang dirasakan pada sejumlah segmen tubuh partisipan untuk melihat konsistensi hasil pengukuran aktivitas otot menggunakan EMG. Terdapat dua jenis kaki prostetik yang digunakan pada penelitian ini yaitu kaki prostetik eksisting yang tidak memiliki mekanisme brake control dan kaki prostetik prototipe yang memiliki mekanisme brake control. Selanjutnya, digunakan dua postur tubuh awal yaitu membungkuk dengan sudut tubuh awal sebesar 20° dan 80°. Enam partisipan laki-laki dilibatkan pada penelitian ini. Penelitian dilaksanakan dengan eksperimen di Lab ITB. Data diolah menggunakan Two Way ANOVA with replication, metode Wilcoxon Sign Rank Test dan Friedman Test. Hasil penelitian menunjukan bahwa jenis kaki prostetik berpengaruh signifikan terhadap aktivitas otot erector spinae (ES) sisi kaki normal dan sisi kaki prostetik, gastrocnemius medialis (GC) serta biceps femoris (BF) (p value < 0.05). Postur tubuh awal berpengaruh signifikan terhadap aktivitas otot erector spinae (ES) sisi kaki normal dan kaki amputasi (p value < 0.05). Selain itu, interaksi antara kedua faktor berpengaruh signifikan terhadap otot biceps femoris (BF) (p value < 0.05). Hasil tersebut berbanding lurus dengan pengukuran tingkat ketidaknyamanan. Diketahui bahwa jenis kaki prostetik berpengaruh signifikan terhadap segmen tubuh punggung atas dan bawah sisi kaki normal, betis serta paha (p value < 0.05). Postur tubuh awal berpengaruh signifikan terhadap segmen tubuh punggung atas dan bawah sisi kaki normal, punggung atas dan bawah sisi kaki amputasi, lutut serta betis (p value < 0.05). Interaksi antara kedua faktor berpengaruh signifikan terhadap segmen tubuh punggung atas dan bawah sisi kaki normal dan punggung atas sisi kaki amputasi (p value < 0.05). Kesimpulan dari penelitian ini adalah jenis kaki prostetik prototipe memiliki performa yang lebih baik dalam meminimalkan aktivitas otot dan rasa nyeri di sejumlah segmen tubuh partisipan. Selain itu, postur tubuh awal sebesar 20° merupakan postur tubuh yang terbaik.

Abstract

Warranty plays a crucial role in marketing new products as they signal the quality of the product to consumers. However, implementing warranty also requires warranty providers to incur additional costs known as warranty costs. The annual warranty costs for global automotive manufacturers have increased from 2018 to 2022, with fraudulent warranty claims estimated to account for 3-15% of the total warranty costs. This study aims to develop an effective decision model to minimize warranty fraud on batteries for cars produced by PT. X. Car battery warranty claim data from 2019, recorded and inspected by PT. X, was used to develop a failure model, warranty policy models, and decision-making model using Nash game theory. The findings indicate that the Pro-Rata Warranty (PRW) policy is more effective in reducing warranty fraud. The results also suggest that customer behavior in committing fraud is influenced by several factors, including product reliability, penalty costs, inspection costs, battery manufacturing costs, battery purchase costs, and the period of Free Replacement Warranty (FRW) policy. Optimal inspection strategies and appropriate warranty policies can significantly reduce warranty fraud, thereby reducing the warranty cost burden borne by the warranty provider.

Abstract

Technological developments allow human-robot collaboration resources to be carried out in the rubber (latex) cutting process in plantations. The human-robot collaboration activities are carried out simultaneously in each rubber tree but have different work tasks. Research regarding human-robot collaboration resource costs in the rubber (latex) cutting process activity is still minimal, so it is necessary to discuss and calculate the resource costs of human-robot collaboration by developing mathematical models. Research regarding the resource costs of human-robot collaboration in the rubber (latex) cutting process is still minimal, so discussion and calculations are needed with the development of mathematical models. Mathematical model development is not just a theoretical exercise. The practical goal is to minimize costs by considering human resources, robots, and human-robot collaboration. Through rigorous testing, we aim to minimize the cost of each resource. Test results show that human-robot collaboration resources can significantly influence cost minimization. Cost minimization is accomplished by programming an algorithm in optimization software. This program is used to make it easier to complete the optimal solution in terms of relatively fast time, which refers to the precedence diagram of the rubber (latex) cutting process.Based on the results of experimental data, the development of a mathematical model functions logically to solve resource placement problems, resulting in a minimum cost of IDR 1,618,234,564,595, total human resources of 1 person and robot resources of 1 unit.

Abstract

As a nation situated within the Pacific Ring of Fire, Indonesia is home to numerous volcanoes. Of the many active volcanoes present, approximately 40% are inadequately monitored. This situation positions Indonesia as one of the countries facing a significant threat from volcanic disasters. One of the critical challenges in disaster management lies in the logistics of disaster relief, particularly in managing perishable food supplies to meet the needs of affected victims. The handling of such logistical items must ensure that no expired products are utilized. One approach to addressing this challenge is to delegate management authority to third parties, specifically vendors who also handle daily demands. This strategy is intended to allow perishable products to be managed through rotation to fulfill all requests while vendors maintain vigilant oversight of existing inventory levels in warehouses. This research aims to evaluate the risks that a vendor must confront when implementing such a collaborative arrangement. The evaluation is conducted using Monte Carlo simulation to determine the optimal scenario that vendors can select. Analysis results indicate that the implementation of Scenario 2, which assumes that a disaster may occur once throughout the planning period, represents the most favorable scenario for vendors. The study underscores the importance of proactive disaster preparedness and efficient resource management in a country prone to volcanic activity. By exploring innovative approaches to logistics and inventory control, stakeholders can enhance their capacity to respond effectively to potential disasters, ultimately contributing to improved disaster resilience in Indonesia.
