Abstract

Production scheduling is generally based on the assumption that resources are always available. In reality, these resources, machines, and supporting facilities experience limited availability due to interruptions during the production process. Therefore, to improve these conditions, the maintenance process conducted to reduce the disruption level of the machine needs to be scheduled as part of the available for job processing leading to penalty costs, such as tardiness and earliness. This research aims to develop a new algorithm to solve job shop scheduling problems to minimize the total penalty cost by considering machine unavailability due to scheduled maintenance activities. The proposed model modifies the existing model using a combination of priority rules and a heuristic approach algorithm known as priority dispatching. The result showed that the proposed model produces a greater total cost with a larger flow time than the previous model. Although the flow time is larger, it is more realistic according to real conditions because the proposed model considers machine maintenance activities. Furthermore, the combination of priority rules used also affected the flow time and the total penalty costs incurred, which can be minimized through several alternatives.

Abstract

Small and medium enterprises in flour processing still rely heavily on manual drying processes, which pose high risks of musculoskeletal disorders and low productivity. This community service program aimed to implement an ergonomically designed spreading and leveling machine to improve working posture and production performance at Kusuka Ubiku SME in Bantul Regency. The program was conducted through problem identification, assessment of workers’ physical complaints using the Nordic Body Map, posture risk analysis using Rapid Entire Body Assessment, ergonomic machine design based on anthropometric data through the Need–Idea–Decision–Action approach, followed by on-site implementation and mentoring. The results show a significant reduction in posture risk from a high-risk category to a low-risk category and an increase in worker productivity by 53.6 percent. These findings demonstrate that the application of ergonomics-based appropriate technology effectively enhances occupational health and operational efficiency in food-processing SMEs.

Abstract

Land use change is a critical phenomenon that demands attention, particularly in metropolitan centers and developing cities in Asia and Southeast Asia that are undergoing substantial urbanization. The objective of this study is to examine the repercussions of land use modification on the environment, society, and economy. Additionally, it seeks to assess prevailing research trends in this domain through a bibliometric approach. The research methodology encompasses bibliometric analysis employing the Scopus database, encompassing the collection and filtration of data from 1986 to 2025, yielding 193 pertinent documents. The analysis indicates that publications in this field have exhibited significant an annual growth rate, reflecting a notable increase in scholarly interest in this subject. The study also found that China and the United States are the countries with the highest publication contributions, highlighting the importance of international collaboration in this research. The discussion revealed that land use change contributes to environmental degradation, biodiversity loss, and negative impacts on public health, particularly in developing countries. Moreover, this study identifies the need to expand studies in underrepresented countries and emphasizes the urgency of sustainable policies to address the challenges posed by land use change. The findings of this research are anticipated to offer insights that will inform the development of more effective and sustainable urban management and regional development policies by relevant stakeholders.
