Efficiency problems in spatial planning at LSU Farm have a significant impact on the effectiveness of the production process. The proximity of raw material storage warehouses to sorting and packaging zones results in congestion that disrupts product flow and quality, as well as triggering backtracking and line crossings that are detrimental to materials management. To overcome this, the Activity Relationship Chart (ARC) method was applied which considers interactions between critical areas such as inbound, sort & repack, outbound, warehouse, employees, cold storage and outdoor offices. ARC's analysis compares the importance of connections between facilities for easier access and consumer convenience, as well as reducing unnecessary movements and improving quality control. The analysis results show that the sort & repack area with the highest Total Closeness Rating (TCR) value (117) is a priority in layout reorganization. Based on these findings, it is recommended that production input warehouses be positioned further away from sorting and packaging areas to maintain product quality and avoid chemical contamination, in line with improving overall operational efficiency.

Layout has an important role in improving the quality of life and productivity of cows. Placing the right layout of space or facilities can make it easier to carry out daily maintenance and upkeep activities. This research was conducted to analyze the layout of facilities at Sapi Juara Farm. Sapi Juara Farm is a privately owned dairy farm located in Kec. Pamijahan, Bogor Regency, West Java. This farm provides fresh cow's milk to meet the demands of the cow's milk processing industry and the community's demand for milk. The layout of this farm needs to be reviewed in order to increase operational efficiency and optimal milk yield. This research aims to investigate and analyze the layout of facilities at Sapi Juara Farm using the Activity Relationship Chart (ARC) and Total Closeness Rating (TCR) methods. The results of the analysis of the two methods showed that the highest score was in the feed warehouse with a total score of 331 and the lowest score was in the owner's house with a total score of 15. The equipment warehouse underwent changes to be placed adjacent to the sterilization room to make it easier to clean the equipment and the process of transporting the milk out.
 
 

Supermarket x is a retail shop that sells various types of products ranging from home necessities, kitchen necessities, food and drinks. The importance of layout in retail is needed to make it easier for consumers to reach the goods they need. Supermarket x has a less effective layout, especially in arranging display shelves. This research aims to make recommendations for layout, especially new display shelves that are more efficient so that consumers can easily reach the items they want to buy. This research uses the Activity Relationship Chart (ARC) and Total Closeness Rating (TCR) analysis methods. The results of the research show that there is a change in the placement of goods on display shelves, after using ARC and TCR, the placement of goods on display shelves is arranged based on the closeness grouping of goods types, shelves 4 and 5 have a value of A (absolute) so the shelves must be close together, while shelf 2 with shelves 4, 5, 6, and 7 have undesirable adjacent X (prohibited) values. Shelf 5 which contains snacks has a high ARC value of 121, so shelf 5 will be allocated first, because snacks are most often sought after by consumers.
