Abstract

Cutting forces analysis of turning process are one of the mandatory lecture contents given in mechanical and manufacturing department. It is because they are related to the quality of the product produced. Therefore, being able to observe and interpret cutting forces can provide an overview of machining quality of the machine. This experimental research explored the effect of spindle rotational speed on cutting process using a full octagonal shaped rings dynamometer made in the laboratory. The results showed that increasing the spindle rotation speed affected the cutting time, whether the greater the spindle rotational speed used, the faster the turning process were completed, each of which is 312.5; 156.25; and 112 seconds. However, variational of spindle rotational speed did not affect the cutting forces of turning process even though the cutting force graph showed fluctuations. Those are due to the dynamics of the machining process. Spindle rotational speed also influenced the frequency content of the process. Various characteristic frequencies of the turning process could be observed, including the spindle rotation frequency (fs) and harmonic frequencies.

Abstract

Islamic boarding school is a unit of educational institution that have functions as a Islamic education. This program partner is Pondok Pesantren Al-Ishlah Bandar Kidul at Kediri City. This Islamic boarding school has hundreds of students from various regions in Indonesia and has several activity areas such as halls, classrooms, canteen, beds, ablution places, and bathrooms. These places are public places that are touched by many people. Therefore, in order to avoid accidents and occupational diseases, it is necessary to map the implementation of Occupational Health and Safety (K3) before the students begin their activities. In this program, the students were given training on K3 and made mind mapping in the boarding school environment. It aims to make the students aware of and understand the importance of implementing K3 in their daily life. In addition, this program aims to prevent the transmission of Covid-19. The steps for implementing this community service program are observation, formulation of priority problems, training design, training, and evaluation. The results obtained from this program are that students understand K3 well and able to implementation of K3 through mind mapping.
