Abstract

The article describes a concept of health and safety to conduct research in Nanomaterial Laboratory in Two Public University in Malang, East Java, Indonesia. The utilization of nanomaterials in the world of education has been done in two universities in Malang, namely Malang State University and Brawijaya University. The nanomaterial laboratory as a means for research and development of nanomaterial science that often creates hazards and risks of work accidents for its users, but things that are often not realized. Dangers and risks of work accidents caused by the absence of standards. This research focuses on hazards and accidents in the nanomaterial laboratory using the HIRA (Hazard Identification and Risk Assessment) method, which is then followed by a variety of independent variables. The population in this study were nanomaterial researchers at two universities in Malang. Based on the results of trials between respondents 'competency expertise with the level of risk of workplace accidents in the nanomaterial laboratory obtained p- value 0.00 (<0.05), meaning that there is a significant relationship between the respondents' scientific conservation and the level of work accident risk in the nanomaterials laboratory. Furthermore, the results of the study were also obtained between the research respondents with the level of risk of work accidents in the nanomaterial laboratory with a p-value of 0.00 (<0.05), meaning that there was a significant correlation between the respondent's research experience and the level of work accident risk in the nanomaterial laboratory.

Abstract

Modern technological progress has inspired numerous innovations that enhance efficiency in human activities, with agriculture remaining one of the most vital sectors for sustaining national economies. Appropriate technologies increase productivity while reducing dependence on traditional practices that demand excessive time and labor. This research presents the design and development of an agricultural drone created for seed spreading. The system employs a 300 Rpm DC motor that drives a propeller to ensure even seed distribution. Performance evaluation compared manual seed spreading and the drone-based method. Results demonstrated that manual spreading required an average of 3.33 hours per kilogram of seeds, whereas the drone accomplished the same task within 1 minute 20 seconds (80 seconds) per kilogram. These findings confirm that drone-assisted seeding offers an efficient and practical approach that supports the advancement of modern agriculture.
