Abstract

Manual material handling (MMH) merupakan suatu kegiatan memindahkan beban yang dilakukan oleh tubuh secara manual. Salah satu contoh dari pekerjaan manual material handling dilakukan pada industri penggilingan padi. Pekerja penggilingan padi akan berpotensi menimbulkan risiko terhadap bahaya fisik dalam hal keluhan nyeri punggung, bahu, lengan dan kaki atau dikenal dengan musculoskeletal disorders. Tujuan penelitian ini adalah menganalisis postur tubuh pekerja pada saat melakukan manual material handling dan menilai apakah postur kerja yang dilakukan oleh pekerja dapat menimbulkan risiko terjadinya musculoskeletal disorders atau tidak. Metode yang digunakan pada penelitian ini adalah Rapid Uper Limb Assessment (RULA) dan Rapid Entire Body Assessment (REBA) kedua metode tersebut merupakan evaluasi cepat yang digunakan untuk menilai suatu pekerjaan memiliki risiko gangguan sistem otot-rangka. Hasil yang diperoleh dengan menggunakan kedua metode menunjukkan bahwa hampir seluruh kegiatan yang didokumentasikan pada penelitian ini memiliki tingkat risiko yang cukup tinggi dan berbahaya sehingga dapat menimbulkan gangguan muculoskeletal bagi pekerjanya. Rata-rata score REBA adalah 9 dan rata-rata score RULA adalah 7, dimana kedua score ini sudah termasuk dalam risk level high. Oleh karena itu, perlu diadakan perbaikan dan perubahan pada tata cara kerja untuk mencegah terjadinya musculoskeletal disorders pada pekerja penggilingan padi di UD. XYZ.

Abstract

The rapid development of industry in the modern era has resulted in increasingly fierce competition between manufacturing and service companies, encouraging companies to compete to provide superiority to consumers. A warehouse is one part that has a vital role in ensuring the smooth running of production activities. The purpose of the warehouse in this research object is as a place to receive raw materials, WIP (Work In Process) and finished goods from manufacturers, maintain stock accuracy based on planning, maintain good quality and control stock properly for export. The object observed is warehousing management in Vendor Managed Inventory (VMI) and Non-VMI warehouses. The problem that occurs is that the material is not placed in its place due to the addition of several new models. The results of the observations were analyzed using a tree diagram. Analysis of the root causes of the problem using a tree diagram obtained four main factors causing the problem, namely humans, SOPs, materials and the environment. The root causes of the four factors are the lack of communication and information between staff, the staff having multiple jobs, so the focus is divided, the flow of goods in and out does not follow the FIFO rules, the absence of temporary storage areas, not an optimal use of the warehouse and the addition of new models, causing the need for there is an improvement in the layout of the Non-VMI warehouse.

Abstract

Agro-industry is a sector that has quite diverse development potential, especially in the field of processing. One of them is processing fruit into fruit juice drinks. Nozy Juice is classified as an advanced MSME, but its competitive level is still lower than other agro-industry. This is because almost all of Nozy Juice's production activities are still done manually, giving rise to various risks that have an impact on decreasing the company's productivity level. To reduce this risk, a fuzzy-based House of Risk (HOR) approach is used which aims to identify the most critical risk agents. Then the risk mitigation design is carried out as an action plan. The essential risk of the 15 risk agents was a human error with an Aggregate Risk Potential (ARP) percentage of 24.275%. Furthermore, a risk mitigation design is carried out for 10 risk events. This is expected to minimize risks in the production process of packaged fruit juice drinks at Nozy Juice.

Abstract

The distribution route is a common issue faced by companies. Companies need to distribute goods to optimize delivery and operational shipping costs. Company XYZ distributes goods to 9 retailers. The problem encountered is that delivery relies only on the intuition of the delivery operators, which is considered suboptimal. Therefore, finding the shortest distribution distance is necessary, one of which can be done using an evolutionary algorithm. An evolutionary algorithm is a population-based stochastic search used to find optimal solutions to a problem. Additionally, distributing goods using the nearest neighbor method determines the route based on the shortest distance between retailers. Thus, the purpose of this study is to find the shortest distribution distance for goods delivered to 9 retailers using an evolutionary algorithm and the nearest neighbor method. The results show that using the evolutionary algorithm, the minimum total distance is 54.5 kilometers, with the route being warehouse-2-1-5-9-4-6-7-3-8-warehouse, while using the nearest neighbor method yields a distance of 55 kilometers, resulting in a difference of 0.5 kilometers.

Abstract

The industrial visit to Beryl's Chocolate Confectionery Sdn Bhd in Malaysia aimed to strengthen the competencies of lecturers and student entrepreneurship advisors at Syiah Kuala University in the areas of global business strategy, technological innovation, and business sustainability. The primary challenge addressed was the need for enhanced understanding and application of entrepreneurial principles to support student entrepreneurship programs, aligning with SDG 4 (Quality Education), SDG 8 (Decent Work and Economic Growth), and SDG 12 (Responsible Consumption and Production). Utilizing the service learning method, this community service activity involved experiential learning through direct observation and engagement with industry best practices. The results demonstrated a significant improvement in participants knowledge and understanding, with an average increase of 22.67% between pre-test and post-test scores. Participants gained practical insights into production processes, digital marketing strategies, and sustainability principles that could be applied to local entrepreneurial contexts. The collaborative involvement of various stakeholdersuniversity departments, industry partners, and travel service providersensured the activity's success and served as a model for future initiatives. This program not only addressed existing knowledge gaps but also opened avenues for integrating global business practices into local entrepreneurship development, contributing to the broader goals of sustainable economic growth and education quality improvement.
