Abstract

Shallot (Allium ascalonicum L.) is one of the main vegetable in Indonesia and has many benefits. However, the production of shallots has not been stable in the past few years due to crop failures. Tree Caured by attacks by plant-disturbing that can reduce yields by 50%-75%. Banana waste has not been widely used for compost, while the potential for banana waste contains important. Manure compost is a provider of nutrients that are gradually renewed and available to plants. Soil fertilized with cow manure for a long time can still give good results. This research method used a factorial randomized block design consisting of 2 factors, namely 1). Banana Waste Compost FHIA-17 (P) consists of 4 levels, P0 = Control, P1 = 5 tons/ha, P2 = 10 tons/ha, P3 = 15 tons/ha. 2) Cowshed Compost (K) which consists of 4 levels, namely K0 = Control, K1 = 5 tons/ha, K2 = 10 tons/ha, K3 = 15 tons/ha. The results of this study showed that the application of FHIA-17 banana waste compost did not show a significant effect on the growth and production of shallot plants, and the application of cow manure compost did not show a significant effect on the growth and production of shallots.

Abstract

Plants can listen to sounds and respond to these sounds by changing metabolic activity. A good sound will have a positive effect on plant metabolism and vice versa. The adhan to prayer is a call to pray and contains good sentences. This study aims to determine the effect of the sound of the adhan on the growth, production, and disease incidence of the Brassicaceae family. This was conducted by performing split plot design which consisted of 2 factors namely plants spesies and the sound of the adhan. The plant species consisted of 3 treatment levels, namely: A1= Mustard greens, A2= Kailan, A3= Pakcoy. Meanwhile, frequency of the adhan consists of 7 levels, namely: B0= without adhan, B1= 2 times a day, B2= 3 times a day, B3= 4 times a day, B4= 5 times a day, and B5= 6 times a day. The results showed that there was a tendency for differences in plant height, leaf area, plant total fresh weight and net weight given the sound of the adhan compared to without sound, but statistically it was not significantly different. The more often the plant is played the sound of the adhan can increase the production of the brassicaceae family.
