Abstract

The supply of hydroponic nutrients needs to consider economic, practical and resource saving aspects. It is necessary to know the best composition and type of nutrients that can be used in a hydroponic system. The use of liquid organic fertilizers (POC) as an alternative to hydroponic nutrients, especially in the wick system, has already begun including widely available alternative fertilizers such as NPK + Gandasil and utilizing chicken feather waste that has been made in the form of fertilizer. This research is expected to provide an overview of the potential for alternative nutrient sources for hydroponic growing media by utilizing the available resources. The study was started from June to August 2020, using a single randomized block design (RBD) consisting of 5 (five) treatment levels, namely: K0 = AB mix (control) 50 ml / 10 L water, K10 = 10 g NPK + 5g Gandasil / 10L water. K11 = 1/2 dose of Abmix + ½ dose of NPK + Gandasil, K12 = ½ dose of NPK + Gandasil + 4800ml / POC of chicken feathers / 10L of water, K13 = 1/2 dose of Abmix + 4800ml / POC of chicken feathers / 10L of water. The results showed that the type of nutrient media composition had no significant effect on plant height in weeks 1,2,3 and 4, leaf length weeks 1 and 2 and number of leaves weeks 1,2,3 and 4. The type of nutrient media composition had a significant effect on leaf length weeks. 3rd and 4th week.The best treatment was obtained at K0. (Abmix), which was significantly different from k10 and k12 treatments, and not significantly different from all k11 and 13 treatments.At week 4, the best leaf length was also obtained at different k0 treatments. real with all other treatments. There is potential for alternative nutrient utilization, because it is able to approach growth using standard nutrients for variables of plant height and leaf number.

Abstract

The variation in soil permeability levels as a result of several types of land use on dry land in Aceh Besar district is not widely known. Therefore, a study of the ability of soil to pass water (soil permeability) as a result of various land use patterns is very important to conduct research in order to maintain a sustainable environment. The metode of research used is directly survey method. The Field survey carried out by taking soil samples that were taken in a composite manner in the processing layer (0-20 cm) and intact. The variables measured include: permeability, soil organic fraction. Intact soil sampling is carried out using a ring or tube to determine soil permeability based on the constan head method. Meanwhile, composite soil samples, which are samples collected from several observation points mixed evenly into a homogeneous sample, those were used to variable soil organic fraction content using the pipette method. Permeability in the type of land use forest shrubs, mixed gardens, moor and teak forests were classified into the medium class. The order of increasing permeability starts from the type of land use for forest shrubs, mixed gardens, moorlands, teak forests and rainfed rice fields. Permeability rates didn't have correlation with organic matter content in several types of dry land use in Aceh Besar district. By increasing sand content, the pores between particles increase, the capillary action weakens, and water easily evaporates through the macro pores, or directly penetrate deep into the soil for vegetation use By increasing clay content, the effect of soil on local rainfall redistribution on vegetation growth changes from decreasing to increasing whereas sand, on the other hand, those was based on a limited distribution of soil types only with high clay content

Abstract

Papaya propagation from seeds has a major problem, namely seed germination takes a relatively long time. Experiments to determine the effect of gibberellin and cow bio urine concentrations on the growth of papaya seedlings were carried out at the Main Horticultural Seed Center of the Agriculture and Livestock Service Office of Buleleng Regency with an altitude of ± 200 m above sea level. The experiment used a factorial randomized block design consisting of two factors, namely the concentration of gibberellin and the concentration of bovine bio urine. Application of gibberellin significantly affected plant height, root length, root wet weight, root oven-dry weight, leaf wet weight, leaf oven-dry weight, total fresh weight, and total oven-dry weight. Gibberellin with a concentration of 150 ppm gave the highest total fresh weight and oven-dry weight, namely 14.63 g and 1.44 g respectively compared to other treatments. The concentration of cow bio urine had a significant effect on root length, very significantly on plant height 40 DST and 47 dd, stem oven-dry weight, leaf wet weight, leaf oven-dry weight, total fresh weight, and total oven-dry weight. Biourine with a concentration of 200 ml.l-1 gave the highest yield in total oven-dry weight per plant, namely 1.19 g. The combination of the concentration of gibberellin and bovine bio urine significantly affected the root length of the plant.
