Abstract

The aim of the study was to determine the effect of liquid organic fertilizer application of palm sap and jackfruit waste on the growth of mustard greens and the optimum dose of LOF on mustard greens. The research was carried out from November 2020 - March 2021 in the yard of the house in Carep Village, Langke Rembong District, Manggarai Regency, East Nusa Tenggara with an altitude of 1,171.5 m above sea level and at the Soil and Environment Laboratory, Faculty of Agriculture, Udayana University. The design used in this study was CRD (Completely Randomized Design) with 6 treatments and 4 replications. The LOF dose treatments P0 = 0 ml/l water, P1 = 5 ml/l water, P2 = 10 ml/l water, P3 = 15 ml/l water, P4 = 20 ml/l water and P5 = 25 ml /l water. Parameters observed were plant height, number of leaves, plant fresh weight and plant dry weight, total number of microorganisms in the soil, pH, organic C, total N, available P, available K and soil moisture content. The results showed that the application of liquid organic fertilizer from jackfruit waste on mustard plants (Brassica juncea L.) had a very significant effect on the parameters of available K, moisture content, total microbial population, plant height 21 DAP, fresh plant weight and oven-dried plant weight, gave a significant effect on the parameters of N-total, plant height 14 DAP and 28 DAP and had no significant effect on organic C, soil acidity (pH), available P, plant height 7 DAP. This study has not found the optimum dose because the highest dose treatment (P5) is still increasing.

Abstract

Civet (Paradoxurus hermaphroditus) are carnivorous animals, but also often eat fruit and one of them is coffee cherries. The coffee cherries that are eaten are not completely digested, so the coffee beans come out with the civet feces. In the civet digestion there are various kinds of bacteria that help the digestive process, one of them is cellulolytic bacteria. It is possible that coffee beans in civet feces contain cellulolytic bacteria.This study aims to determine the presence of cellulolytic bacteria in civet feces. The results of bacterial isolation in civet feces obtained 6 isolates that had different morphological characters. Cellulolytic bacteria screening results showed that 2 out of 6 isolates were positive as cellulolytic bacteria, namely FL2 isolate with a cellulolytic index of 2.38 (high reaction) and FL3 isolate with a cellulolytic index of 1.24 (medium reaction). The isolates FL2 and FL3 had different morphological characters in colony shape, margins and color, but had similarities in elevation, gram color and cell shape.
