Groovy Space Coffee and Kitchen is a coffee shop located in the Bogor City area that serves several types of drinks such as coffee and tea and several foods, both snacks and heavy meals. This research aims to optimize the layout of the sitting room at Groovy Space Coffee and Kitchen using the Activity Relationship Chart (ARC) method based on the results of the Total Cleseness Rating (TCR) calculation. The ARC method is used to determine optimal seating space layout arrangements by considering the shape of the room and the available area. Meanwhile, the TCR method is used to overcome potential conflicts in the use of seating space, such as the density of visitors at certain times. The application of these two methods is expected to produce a seating space layout that is efficient, comfortable, and able to better accommodate the number of visitors. The results of this research show that the new layout is more effective and efficient compared to the previous layout with the results showing that the new layout includes additional seating in the outdoor area and also a change in concept from outdoor to semi-outdoor.

In the era of increasingly rapid globalization, the industrial world is faced with inevitable dynamics. One important aspect in industry is optimal layout planning. The right layout determines the effective placement of production facilities, thereby smoothing the production process and increasing productivity. The current layout of production facilities at Bebeke Om Aris Dramaga is not optimal, causing production inefficiencies and increased costs. This research aims to redesign the layout of facilities at Bebeke Om Aris Dramaga. This research examines the design of alternative layouts at Bebeke Om Aris Dramaga with the aim of increasing productivity. The methods used are Activity Relationship Chart (ARC) and Total Closeness Rating (TCR). Production location calculations are carried out periodically to obtain accurate information. The research results show that the proposed layout has shorter distances between facilities. Apart from that, the resulting service time is more optimal. This change in store layout shows that the new layout is more effective and efficient than the old layout. This is proven by research results which show that the new layout design can reduce the time spent by employees in the production process and service to customers and the distance between facilities and increase the efficiency of employee movement.
