Abstract

One of the most important stages in the process of transferring in vitro cultured seedlings to their natural environment is the acclimatization stage. The acclimatization stage is a critical period in plant propagation. The factors that most influence the growth of in vitro seedlings in the acclimatization process are suitable planting media and the administration of biostimulants. This study aimed to obtain the best planting medium and type of biostimulant for the growth of black orchid plantlets at the acclimatization stage. The study used a completely randomized design with a factorial pattern with two factors, namely first factor: type of growing media with 5 levels of treatment (wood sawdust, coconut coir, cocopeat, rice husk, sugarcane dregs) and second factor: type of biostimulant (without biostimulants; Moringa oleifera extract; Centella Asiatica extract; and Melastoma malabathricum extract). The results showed that the highest percentage of plantlet survival (100%) in the early stages of acclimatization was shown in plantlets grown on wood sawdust and coconut coir media. At the advanced acclimatization stage, the type of biostimulant significantly affected the parameters of survival percentage, tiller height, average number and width of leaves, and average number and length of roots. Optimal planting medium and biostimulant type for advanced acclimatization orchid growth is a single treatment of wood sawdust media with a tiller survival rate (100%), the highest number of leaves (4.65 strands), most roots (8.4 strands).

Abstract

Red onion is a rural commodity developed by people in West Kalimantan. The development of shallots in West Kalimantan is mostly completed in the formation of media in the form of peat soil with physical and substantive qualities that are unfit for the production of shallots. The application of Liquid Organic Fertilizer (LOF) is one method used to overcome the limitations of shallot cultivation on peatlands. The aim of the study was to determine the production of shallots of the Bauji variety influenced by a mixture of liquid organic fertilizer containing waste pineapple skin and water hyacinth. The study used an experimental method with a completely randomized design (CRD) and there were seven treatment standards for liquid organic fertilizer. The results of the study found that liquid organic fertilizer mixed with water hyacinth waste and pineapple peel had an effect on tuber wet weight, tuber dry weight, tuber number and tuber diameter. The best concentration is on. LOF treatment of 50 ml/L to increase the production of shallots of the bauji variety planted on peatlands in West Kalimantan. This treatment resulted in the highest tuber wet weight value of 55.07 grams and tuber dry weight of 15.22 grams, the number of tubers was 8 pieces and the tuber diameter was 2.44 cm.

Abstract

Eco-enzyme is a fermented product from an organic waste substrate, molasses, and water. Eco-enzyme can be used as antibacterial because it produces organic compounds such as alcohol and acetic acid. Pineapple peel waste (Ananas comosus L.) can be used as an eco-enzyme. This study aimed to test the antibacterial activity of pineapple peel eco enzyme against Pseudomonas aeruginosa and Staphylococcus epidermidis. The study used the method of determining the Minimum Inhibitory Concentration (MIC) and Minimum Killing Concentration (MBC) of pineapple peel eco-enzyme with 8 treatment levels namely negative control (aquadest), positive control (ciprofloxacin 5 mg/mL), 3.125%, 6.25 %, 12.5%, 25%, 50%, and 100% eco-enzymes. Based on the research results, it was known that the MIC value of pineapple peel eco-enzyme against P. aeruginosa, and S. epidermidis was 12.5% and 3.125%, respectively. Eco- enzymes from pineapple peel did not show minimum killing concentrations. Eco-enzyme of pineapple peel is only bacteriostatic towards the growth of P. aeruginosa and S. epidermidis bacteria.
