Abstract

Gambas (Luffa acutangula, L.) is an annual vegetable plant belonging to the fruit vegetable group originating from India, but has adapted well in Southeast Asia including Indonesia. This study aims to determine the effect of liquid organic fertilizer application from tempe industrial waste and application of onion peel compost on the growth and production of gambas. This research method uses a factorial randomized block design (RAK) which consists of 2 factors, namely: application of liquid organic fertilizer from tempe industrial waste and onion skin compost. The provision of liquid organic fertilizer for tempe industrial waste consists of 4 levels of treatment, namely: B0 = control/without treatment, B1 = Liquid Organic Fertilizer 22 ml/L, B2 = Liquid Organic Fertilizer 44 ml/L, B3 = Liquid Organic Fertilizer 66 ml/L L. The second factor of onion peel compost consisted of 4 levels of treatment, namely: P0 = Control/without treatment, P1 = Shallot Skin Compost 10 tons/ha (1.2 kg), P2 = Shallot Compost 20 tons/ha (2 ,4 kg), P3 = Compost of Shallot Skin 30 tons/ha (3.6 kg). Observation variables included: plant length (cm), number of leaves (strands), fruit diameter per sample plant (cm), fruit length from sample plant (cm), fruit weight per sample plant (g), fruit weight per plot (g), number of fruits per plot (g). The results showed that the combination of liquid organic fertilizer from tempe industrial waste and onion peel compost had a significant effect on plant length and fruit weight per sample plant, but had no significant effect on leaf number, fruit diameter, fruit length, fruit weight per plot and number of fruits per plot.

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).
