Good planting media is a medium that is able to provider water and nutrients is sufficient quantities for plant growth. This can be found on soils with good air conditioning, has a solid aggregate, good water holding ability and room for sufficient rooting. Proper use of media will provide optimal growth for the plants. This study aims to determine the best planting medium to support the growth of coffe seedling Liberika Tungkal Komposit. The research was conducted in the experimental garden Pijoan, University Batanghari Jambi. From March to May 2017. The research design in this experiment was planting medium with complete randomized environmental design (RAL). The treatment is : M0 = plant medium 100% peat soil, M1 = plant medium 100% ultisol soil, M2 = planting medium 50% untisol soil + 50% rice husk charcoal, M3 = planting medium 50% ultisol soil + 50% cocopeat, M4 = planting medium 50% ultisol soil + 50% river sand, M5 = planting medium 50% peat soil + 50% rice husk charcoal, M6 = planting medium 50% peat soil + 50% cocopeat, M7 = planting medium 50% peat soil + 50% river sand. Parameter observed were plant height, stem diameter, root length, crown dry weight, root dry weight, root canopy ratio, total dry weight, quality index, initial pH media and final pH media. The result showed that the ultisol 100% ultisol garden media gave the heighes seed growth value based on single parameter ie plant height, stem diameter, root lenght, crown dry weight, root dry weight, root canopy ratio, total dry weight, and initial media pH and treatment integrated quality index that indicates that the seed is most ready to be moved to the field.Keywords: nurseries, plantations, coffee AbstrakMedia tanam yang baik adalah media yang mampu menyediakan air dan unsur hara dalam jumlah cukup bagi pertumbuhan tanaman.

AbstractProduction and quality of latex is determined by planting distance of rubber plants. This research aimed to know the production and quality of latex in various the rubber plant planting distance range. The research was carried out in August until September 2016 . The research method design was a survey method. The different planting distance which is use was already exist in “Durian Inner Luncuk XXIV” Villages, Batanghari Regency i.e.; J1 (3 x 4 m), J2 (3 x 5 m), J3 (4 x 5 m), and J4 (4 x 6 m) as treatments. Each treatment was set 15 plant samples. The parameters observed were the latex production, the dirt levels, the ash levels , and the levels of dry rubber. The observation result showed that the highest latex production (130 gr-1 plant-1 day-1) was obtained at the planting distance treatment of 4x6 m. Levels of impurities in LaTeX, the levels of ash and the highest levels of the dried gum obtained at the treatment plant distance is 4 x 5 m i.e. 0.024 0.20%, and 18.43%. The difference in distance is not planting showed a different result against the level of dirt, the levels of ash and dried gum levels.Keywords: planting Distance, production, quality Latex, gum plant AbstrakProduksi dan kualitas lateks salah satunya ditentukan oleh jarak tanam tanaman karet.
