| Summary: | Food security in Indonesia is threatened due to the conversion of agricultural land and land degradation as well as the Covid-19 pandemic that disrupts food distribution so agricultural system with efficient use of space and environmentally friendly planting media that can be applied at the household scale is needed. Urban farming can be a solution to these problems through the raised bed method and the intercropping system as well as organic growing media that can be applied in home gardens and dense urban areas. This study aimed to determine the best composition of layered planting media on raised beds for growth and biomass production of red bean (Phaseolus vulgaris L.) and corn (Zea mays). The research was conducted at the SITH ITB Educational Garden in Haurngombong Village, Pamulihan District, Sumedang Regency, West Java. This study used a completely randomized design and consisted of 3 treatments for the composition of the growing media, namely TP (soil, manure), STPK (litter, soil, manure, compost), and STPKM (litter, soil, manure, compost, mulch). Parameters observed were edaphic conditions of the media (porosity, bulk density, nutrient content, and number of soil organisms), weathering conditions of cardboard and raised bed wood, plant growth (plant height, number of leaves, and RGR), and biomass production (fruit weight, plant weight, and root shoot ratio). The results of the media edaphic conditions showed that the best treatment was STPK with porosity, bulk density, and soil organisms values, namely 81.73%, 0.49 g/cm3, and 272 organisms. The lowest wood damage was shown in the STPKM with a value of 25% and cardboard weathering gave the same results in all treatments, namely 100%. The results on the growth parameters showed that STPKM gave the best effect on plant height, number of leaves, and RGR value with the total percentage of influence on each parameter, namely 67.96%, 69.73%, and 69.89% as well as on biomass production parameters. , the highest results were shown by TP on fruit weight and plant weight and STPK on root: root ratio with the total percentage of influence on each parameter, namely 70.83%, 70.45%, and 71.98% so that in general, the TP treatment gives the best results on biomass production parameters.
