Abstract
Physical properties of soil are good for plant growth is closely related to the management of the soil, so it will need to integrate of physical properties to get an overall assessment with making soil physical quality index (SPQI). This study aims to an evaluation of physical properties and determines the physical quality index using several unit treatments to produce various physical qualities on Groundnut/Arachis hypogeal L. The location of the research was carried out in a farmer's garden in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12’14’’ S dan 106o11’52’’E). To analyze the SPQI using several physical properties of the soil such as texture, bulk density, porosity, permeability, and aggregate stability. Each indicator has a scoring parameter to assess the soil physical quality index with a score range of 0-5. An assessment SPQI in a land unit is able to describe the various physical qualities of the soil which are represented by several physical properties of the soil. The unit treatment which class categorization of soil physical quality index indicated slightly good (U2), medium (U1, U3-U6), and slightly poor (U7) as a control.

Summary
The function of soil will could work optimally if attention to the potential factor of the soil and physical condition of the soil. Good soil workability is when the soil can be cultivated to provide a growth medium for a plant that is supported by the physical qualities of the soil [1]. Physical quality of soil has an important contribution to plant growth, thats 1) as a physical medium for the presence or place of the presence of nutrients, water and gases needed for plants, 2) as a controller for providing available water for plants and 3) as a process controller supply of gases needed for plants [2]. Soil with good physical quality has the ability to provide adequate and appropriate supply of water, air and nutrients for plants so that it is closely related to the management and use of growing plants [3, 4]. Poor soil structure indicates that there has been a decline in the physical quality of the soil
