The research method used was a factorial randomized block design (RAK) consisting of 2 treatment factors, namely, mushroom baglog compost media waste (K) and oil palm kernel biochar (B) where compost treatment was 3 levels and oil palm kernel biochar treatment was 4 level. Factor I: Compost of mushroom baglog media waste with 3 levels of concentration ie K0 = Control (without compost), K1 = Baglog compost of 50 grams / polybag, K2 = Baglog compost of 100 grams / polybag. While Factor II: Biochar palm kernel with 4 levels, namely: B0 = Control (without Biochar), B1 = Giving Biochar Palm Kernel 10 grams / polybag, B2 = Giving Biochar Palm Kernel 20 grams / polybag, B3 = Giving Biochar Kernel 10 grams / polybag, B2 = Giving Biochar Palm Kernel 20 grams / polybag, B3 = Giving Biochar Kernel Palm Oil 30 grams / polybag, each treatment was repeated 3 times.The parameters observed in this study consisted of shoot bud rupture time, shoot height (cm), number of strands (leaves), leaf area, leaf color, stem diameter. The results showed that the treatment given had no significant effect on all parameters.

Abstract:
This study aims to determine the growth and yield of eggplant with chicken egg shell powder utilization and Kascing fertilizer, This research was conducted from March until the month of June 2019. The method used in this study is a randomized block design in factorial, with 2 (two) treatment factors, namely: 1) Factors dose of powdered chicken egg shells (C), which consists of five levels, namely: C0 = control ( without treatment); C1 = chicken egg shell powder 5 g / polybag; C2 = chicken egg shell powder 10 g / polybag; C3 = chicken egg shell powder 15 g / polybag; C4 = chicken egg shell powder 20 g / polybag; 2) Factors Kascing fertilizers (K), which consists of 4 levels, namely: K0 = control (no treatment); K1 = Kascing fertilizer with a dose of 10 ton / ha (25 g / polybag); K2 = Kascing fertilizer with a dose of 20 ton / ha (50 g / polybag); K3 = Kascing fertilizer with a dose of 30 ton / ha (75 g / polybag), each treatment was repeated two (2) times so that there are 40 experimental plots. Each experimental plot consisted of 5 plants with 3 plant samples. The parameters were observed in this study consisted of plant height, leaf area, number of flowers per sample, the number of fruit per sample, production per sample, production per plot and volume of roots. From the research that has been done can be concluded as follows: 1) Giving powder chicken egg shells effect no significant effect on plant height, leaf area, number of flowers / sample, the number of fruit / samples, production / sample production / plot and the volume of the roots of plants eggplant; 2) Fertilizer Kascing significant effect on plant height, leaf area and production / samples as well as very significant effect on the number of fruit / samples and production / plot, but no real effect on the number of flowers / plant samples eggplant; and 3) a combination of administration of a chicken egg shell powder and fertilizer Kascing no real effect on the growth and yield of eggplant.

Abstract:
Dendrobium sp is a type of orchid that is currently very popularly traded because it has a variety of flower types, but the growth rate is slow. Vitamin B1 (Thiamin) is a micro nutrient that is able to accelerate the division of new cells in the tissue so that it can accelerate the growth of plant vegetative organs. Atonic is a chemical that can stimulate the biochemical and physiological processes of plants, so that atonics is a growth regulator. Atonic is usually used to stimulate the growth of plant roots against nutrients, increase leaf absorption, flower discharge, fruit formation, and increase the number and weight of fruit. The purpose of this study is the Stimulation of Growth and Development of Planlet Orchid (Dendrobium sp) in the Acclimatization Stage by Provision of Vitamin B1 and Atonik.This research was conducted experimentally using a completely randomized design (CRD) with 2 factors, namely the concentration of Vitamin B1 (Thiamin) consisting of 4 treatment groups and Atonic consisting of 4 treatments. Vitamin B1 (0 ml / l, 1.5 ml / l, 3 ml / l, 4.5 ml / l) and Atonik (0 ml / l, 1 ml / l, 2 ml / l, 3 ml / l) and each treatment was repeated 2 times so that 128 plants could each treatment consisting of 4 plants with 4 sample plants. Spraying is done once a week. The parameters observed were percentage growth, plant height, stem diameter, number of leaves, primary root length and number of roots and measured at 2MST.Based on the results of research on Dendrobium sp. Can be concluded 1) Provision of Vitamin B1 significantly affect the growth of orchid plant height (Dendrobium sp). 2) The giving of Atonik significantly influences the growth of the number of leaves, root length and number of roots of orchid plants (Dendrobium sp). 3) Provision of Vitamin B1 and Atonik simultaneously can accelerate to overcome plant height, number of leaves and the budding of orchid plant roots (Dendrobium sp).
