Small and Medium Enterprise (SME) Taman Eden 100 or CV Andaliman Mangintir is a manufacturing company that produces various andaliman derivative products, including Andaliman Dried Seeds, Andaliman Powder, SikArsik, and Andaliman Seeds. Some of Andaliman's derivative products are already halal certified and some of them do not yet have a halal certificate but already have a PIRT DINKES permit. Thus, it is necessary to have a different room to produce halal products and products that have not been certified halal, so it is necessary to design a layout using the Systematic Layout Planning (SLP) method. The Systematic Layout Planning (SLP) method has several stages in making the layout, namely activity linkage analysis such as Activity Relationship Chart (ARC) analysis, Activity Relationship Diagram (ARD) analysis, and making proposed layouts based on the 5S concept (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke). Based on the research conducted, it was found that the total travel time and distance of Material Handling in the initial layout within 1 month was 3.720 seconds and 2.155 seconds for the time of Andaliman Powder and SikArsik; and 43,69 m and 88,03 m for the distances of Andaliman Powder and SikArsik. By using the Systematic Layout Planning (SLP) method, it is obtained that the total travel time and distance of Material Handling in the proposed layout within 1 month is 2.800 seconds and 1.465 seconds for the time of Andaliman proposed layout within 1 month is 2.800 seconds and 1.465 seconds for the time of Andaliman Powder and SikArsik; and 31,28 m and 74.32 m for the Andaliman powders and SikArsik, resulting in a reduction in Material Handling time and distance of 920 seconds and 12,41 m for Andaliman Powder products; and 690 seconds and 13,71 m for SikArsik products.

Andaliman is a typical seasoning plant of Sumatra which can be used as a flavouring traditional Batak (arsik) and other derivative products such as crackers, bandrek which have a taste of andaliman. One process that is passed so that Andaliman can be used as a seasoning and other product is drying process. Generally, andaliman drying is done by solar power or dryer. The current condition at the UMKM of Taman Eden 100 is the length of time of drying and limited capacity so that it is unable to meet the demand of arsik instant flavor. This research was conducted by applying the Quality Function Deployment (QFD) method through a questionnaire distributed to owners and workers at the UMKM to determine the desirable desiccant needs. The results of the QFD are mapped into the House of Quality which is expected to be a picture of the new dryer. From this HOQ, it is produced that the user wants a dryer with a larger capacity than before which has a heat control device so that the heat is evenly distributed in the drying chamber. The aroma of andaliman also remains even though the water content in dry andaliman has decreased.
