Abstract

Indigofera tinctoria is a legume that is cultivated as a source of natural indigo dyes. As a legume, Indigofera tinctoria is capable of symbiosis with soil microbes. This study evaluates the effects of light intensity and microbial inoculation on root growth and nodulation. The study used a complete randomized block design with a split-plot pattern. Light intensity was the main plot with four levels of light intensity 100%, 50%, 25%, and 10%. Microbial inoculation was a subplot with four levels without inoculation, mycorrhizae inoculation, rhizobium inoculation, and double inoculation with both mycorrhizae and rhizobium. The results obtained show that light intensity and microbial inoculation affected root length, root fresh weight, root biomass, and the number of nodules. 50% light intensity was optimum for root length, while 100% light intensity was optimum for root fresh weight, root biomass, and a number of nodules. Root growth and nodulation were further increased with double inoculation. The combination of light intensity and microbial inoculation affected root biomass and nodulation. The combination of 100% light intensity and double inoculation resulted in the highest root biomass and nodule numbers. Mycorrhizae and rhizobium have a synergistic relationship to nodulation and root growth. Double inoculation with mycorrhizae and rhizobium efficiently increased root biomass and the number of nodules under low or high light intensity.

Abstract

Kegiatan pengabdian masyarakat bekerjasama dengan CV. Indigo Biru Baru yang merupakan usaha batik pewarna alami di Desa Puron, Kecamatan Bulu, Kabupaten Sukoharjo dengan memanfaatkan tanaman Indigofera tinctoria sebagai pewarna biru alami. Pengelolaan tanaman tersebut sebagai pewarna alami menghasilkan limbah yang belum dimanfaatkan. Permasalahan limbah tersebut mendorong pemanfaatan limbah sebagai pupuk organik padat. Tujuan kegiatan pengabdian yaitu membina mitra dalam pengelolaan limbah ekstraksi sebagai pupuk organik. Metode yang diterapkan yaitu: uji coba pembuatan pupuk organik limbah ekstraksi Indigofera tinctoria, analisis kualitas pupuk organik, penyuluhan dan demonstrasi tentang pemanfaatan limbah sebagai pupuk organik, demontrasi plot budidaya Indigofera tinctoria dengan aplikasi pupuk organik, demontrasi plot budidaya sayuran dengan aplikasi pupuk organik. Hasil kegiatan pengabdian masyarakat menunjukkan bahwa limbah ekstraksi Indigofera tinctoria dapat digunakan sebagai pupuk organik dan memenuhi persyaratan standar sebagai pupuk organik menurut Permentan No.70/ Permentan/SR.140/10/2011. Kualitas pupuk organik meliputi parameter kadar air, N total, P2O5, K2O, C-organik, C/N rasio dan pH menjadi indikator keberhasilan pengelolaan limbah sebagai pupuk organik. Berdasarkan kegiatan penyuluhan menunjukkan bahwa peserta interaktif dan berminat untuk memanfaatan limbah ekstraksi Indigofera tinctoria sebagai pupuk organik. Pupuk organik limbah ekstraksi dapat digunakan sebagai media tanam untuk penanaman sayuran dan pembibitan Indigofera tinctoria. Hasil percobaan menunjukkan bahwa pemberian pupuk organik limbah ekstraksi dapat meningkatkan pertumbuhan tanaman Indigofera tinctoria pada 6 MST. Hasil kegiatan yang diperoleh yaitu peningkatan pengetahuan mengenai teknologi tepat guna untuk memanfaatkan limbah.

Abstract

The productivity of red ginger in Indonesia has decreased by 9,174 tons compared to 2017. The decrease is due to the very limited area of red ginger production, the method of red ginger cultivation, which is still very conventional, and the low amount of organic matter in the soil. This study examines the effect of planting media composition on the growth and production of red ginger. The study used a Completely Randomized Block Design (RCBD) with six treatments, namely control (soil without manure), cow manure: green manure: soil (1:1:1), P2 = goat manure: green manure: soil (1:1:1), green manure: soil (1:2), cow manure: soil (1:2), and goat manure: soil (1:2) and repeated four times. Composition media of goat manure: green fertilizer: soil with a ratio of 1:1:1 could increase the growth of red ginger in variable plant height, number of leaves in the clump, leaf area, and the weight of fresh stover with a yield of 52.7 cm; 10,75; 148,5; 2952.59 cm2; and 307.33 g. Composition of green fertilizer media: soil with a ratio of 1:2 could increase the weight of dry stover with a value of 39.32 g, and red ginger production includes fresh weight of rhizomes 111.32 g, storage weight of rhizomes 107.87 g, and rhizome volume 124.12 cm3.
