Abstract

The demand for batteries is expected to rise in line with the growing need for electric vehicles. As the number of electric vehicles increases, more battery waste will be generated, considering the average battery lifespan is only 10 to 15 years. If batteries are not recycled, this will lead to a significant accumulation of waste. Therefore, it is important to evaluate the ease of battery disassembly. This assessment can help manufacturers design batteries that are easier to disassemble. This study aims to determine the disassembly ease score and provide improvement recommendations using the Ease of Disassembly approach through eDiM and Difficulty Rating. The disassembly process is analyzed using the Ease of Disassembly Metric (eDiM) to evaluate difficulty levels based on standard disassembly operation time, and Difficulty Rating based on the indicators of Accessibility, Positioning, and Force. Based on the analysis results, the most difficult disassembly operations involve removing screws from the top cover, bottom cover, controller circuit, and BMS circuit, as well as detaching the nickel strip. The research findings indicate the presence of disassembly stages with low time values but high preference-based difficulty levels.

Abstract

Every year, a program called a "tracer study" is run to collect and analyze data from graduates (a year after graduation). Seeks to guarantee that graduates have good work and submit it on time following university or institute criteria after graduation. Within 1-2 months of filling it out, a data analyst processes the data and validates its accuracy. Data for 10 study programs were collected, and comparisons were made between the graduation years of 2019 and 2020. In 2020, the Covid-19 pandemic started. The Institut Teknologi kalimantan (ITK) was significantly impacted by Covid-19, which led to all work being done online on campus. Evaluation criteria for ITK include the length of time it takes graduates to find employment, their GPA, the nature of their alumni employment, and their reasons for not finding employment one year after graduation. In order to be able to create more qualified alumni, the rate ranking approach will help examine the success of the study program and provide an evaluation of the study program. This paper's two lowest-ranking disciplines are electrical engineering, materials engineering, and metallurgy..

Abstract

Currently, there are individuals around us living with disabilities caused by accidents or other factors. People with disabilities generally require assistance from others, particularly for mobility or moving from one place to another. Although manual wheelchairs can provide a solution for mobility, they remain challenging to operate using hand power alone and often require external help for movement. To facilitate mobility for individuals with disabilities, especially wheelchair users, an electric drive system in the form of an electric motor is proposed as a solution. The development of a motorized electric wheelchair aims to enhance the mobility of individuals with physical disabilities. Members of the Indonesian Association of Persons with Disabilities (PPID) were selected as community service partners for this initiative. It is hoped that, in addition to supporting mobility, the electric wheelchair can also serve as a body support system, enabling users to continue engaging in productive activities while seated.  The implementation of this program began with interviews conducted with persons with disabilities and related partners to understand their needs, followed by the design, fabrication, and subsequent socialization and training on the use of the electric wheelchair for the target beneficiaries. The outcome of this effort is an electric wheelchair equipped with joystick controls. The wheelchair employs a rear-wheel drive system powered by two motors, each attached to a rear wheel, and a chain transmission system. Along with delivering the electric wheelchair to the PPID, this initiative aims to serve as a practical application of mechanical engineering knowledge, directly benefiting the community..

Abstract

Vocational high school (SMK) students represent a level of vocational secondary education expected to fulfill the demand for technical labor at specific levels within the industry. However, current SMK graduates face challenges due to intense competition in securing employment. This community service initiative aims to enhance the skills of SMK students by focusing on the utilization of Information and Communication Technology (ICT) in the preparation of post-graduation documents. A case study was conducted at a private vocational high school (SMKS) in and state vocational high school (SMKN) in Tanah Bumbu Regency as an effort to prepare students to face the challenges of Industry 4.0. Through outreach activities, this initiative introduced the concept of community service and the benefits of ICT in document preparation. The methods employed aimed to achieve outcomes such as improving students' skills, applying ICT in preparing supporting documents for job applications, and enhancing students' competitiveness in the labor market. The results of the activities carried out showed an increase in participants' knowledge of curriculum vitae and job application letters. Survey results also indicated that the seminar was highly beneficial for participants in this community service activity through technical outreach.

Abstract

As an institution equipped with resources and experts in the field of technology, universities hold significant potential to develop and provide innovative solutions to the challenges faced by the elderly. Therefore, this activity aims to design and implement a specialized walking aid tailored specifically for older adults. This assistive device will be developed with careful consideration of the unique needs and limitations commonly experienced by the elderly. The introduction of such a device is expected to promote greater independence and active engagement among elderly individuals in their daily lives. Ultimately, it is anticipated that this will enhance their overall quality of life and generate positive social impacts across the broader community in Kalimantan. Furthermore, this activity emphasizes the importance of collaborative efforts among universities, local governments, healthcare institutions, and the community in supporting and effectively implementing this initiative. The project will begin with consultations involving neighborhood leaders (RT) and local residents. Upon reaching a consensus, the next stages will involve socialization, the design and development process, and the eventual delivery of a prototype that meets the identified needs.

Abstract

PT. Pupuk XYZ is one of the urea producers in Indonesia, operating Urea Plants with high production performance demands. The purpose of this study is to evaluate the efficiency of the equipment and pinpoint the reasons for the deterioration in performance at Urea Plant Pabrik 2. The methods used include Overall Equipment Effectiveness (OEE), Six Big Losses, fishbone diagram, and Failure Mode and Effect Analysis (FMEA). The average OEE value, according to the data, is 88.32%, which is higher than the world-class benchmark of 85%. Performance (92.49%) stays below the benchmark and becomes the primary limiting factor, whereas Availability (95.10%) and Quality (100%) satisfy the requirements. The primary source of the effectiveness loss is unscheduled downtime, which reached 181.44 hours as a result of key equipment failures. Therefore, the implementation of Total Productive Maintenance (TPM) is proposed to improve equipment reliability and reduce downtime

Abstract

As an archipelagic country with a coastline of thousands of kilometers and enormous oceans with high diversity, Indonesia has very rich fishing resources from capture fisheries. But this maritime treasure is typically under-exploited, poorly managed and vulnerable to environmentally damaging activities. Indonesia can implement effective and environmentally friendly technical solutions to prevent marine pollution. For instance, the use of Solar Power equipment (SPS) in fishing vessels can meet the energy needs of the refrigeration equipment on board. The objective of this study is to investigate the viability of solar panel installation on fishing vessels and its effects on vessel stability. The results showed that the vessel's roof is fitted with eight solar panels, each with a capacity of 500 Wp, to create 14.92 kWh per day to power five refrigeration units. Stability analysis shows that the addition of rooftop solar panels, cooling boxes, and batteries in the fish hold is in compliance with IMO Standard A.749(18) Chapter 3, ensuring the safety of the system for practical application.
