This paper discusses about the manual material handling activities in the UD. Santosa. The activities give a particular injury because of the excessive load. Minimizing manual material handling can decrease and prevent a big number of injuries and fatigue. The increased rate of the injury that happened on the workers is also one of the indicator that there is excessive physical workload. This study aims to minimize the manual material handling and the physical workload by making multifunction trolley using anthropometrics. The method that used in this research is Cardiovascular Load, Anthropometrics. The result shows that the recommended weight load for each operator is 7.30411 kg, 5.93229 kg, 4.949725 kg, 2.88399 kg, and 2.594356 kg to avoid the risk of injury. For the physical workload for operators classified into 60% need to be improved and 40% no fatigue. The size for the multifunction trolley based on anthropometrics is 72.54 cm for the height of incline mode, 134.56 cm for the height of the trolley, 105.813 cm for the height of the of the hand holder, and 9.19177 cm for the width of the hand holder.

Good oral health can be realized through knowledge and good and correct behavior towards the maintenance of dental and oral health. Knowledge is a factor that forms erroneous behaviors and attitudes towards maintaining dental and oral health. A person who has never experienced dental care is more likely to arise anxiety. This study aims to analyze the knowledge picture of the impactation of the third molar teeth and the level of anxiety of the odontectomy action. This type of research is a literature study. Data collection based on the study of literature data is then analyzed. The results of the literature analysis study concluded that the third molar dental impaction knowledge was in the moderate category with a percentage of 74.1%. The results of the study on the level of anxiety showed that before odotectomy, they did not experience anxiety with a percentage of 57%. The results of the literature from Pratiwi's research (2021) show that having a level of knowledge either does not experience anxiety or has lower anxiety. So it can be concluded that the higher a person's knowledge, the lower the level of anxiety felt. Supported by the research of Bachri (2017) that the level of knowledge affects the awareness and understanding of stimuli.

Animal husbandry is one of the agricultural sub-sectors that has an important role in contributing quite significantly to the country’s economy and breeding hens are one of those. In setting up breeding hens that sufficiently adequate it does not require substantial capital. However, many breeding hens in designing the work station are less ergonomic, giving rise to the level risk of musculoskeletal disorder. The aim of this study is to assess the work posture of the operators and from the result of this study, it can be proposed improvement of the work station to improve work posture and to reduce the level of Musculoskeletal Disorder. The method that used in this research is Quick Entire Check, Nordic Body Map, and Anthropometrics. The result showed that the exposure level operator 1 got value 41.47%, the action that needs to be done is need more research to make it safe. While operator 2 got value 55.68%, the action that needs to be done is doing another research and change the activities. Also, it can be seen if the pain felt by the two operators is in the neck, buttock, shoulder, arm, calf, and knee. From the research results, the recommendation given is to redesign work stations that pay attention to work posture by implementing anthropometry and adding several innovations.
