Abstract

This study aims to determine the toxicity of the formulated herbicide concentration to non-target organisms (non-target) earthworms. The study was conducted from April to July 2021. The design used was a completely randomized design (CRD) with nine (9) herbicide concentrations (K) treatments, namely: K0 = control, K1 = 200 ppm concentration (0.2 ml/l water ), K2 = concentration of 400 ppm (0.4 ml/ l of water), K3 = concentration of 600 ppm (0.6 ml/ l of water), K4 = concentration of 800 ppm (0.8 ml/ l of water), K5 = concentration 1000 ppm (1.0 ml/ l of water), K6 = concentration of 1200 ppm (1.2 ml/ l of water), K7 = concentration of 1400 ppm (1.4 ml/ l of water), K8 = concentration of 1600 ppm (1, 6 ml/l water). Each treatment was repeated 3 times. The observed variables were mortality concentration 50 (LC50) for 96 hours, survival rate, mortality percentage and worm weight. This study concluded that the mortality concentration of 50 (LC50) for 96 hours from the formulated herbicide against earthworms was 600 ppm, while the 100% mortality occurred at the herbicide concentration of 1400 ppm. The lowest survival rate was found at a concentration of 1400 ppm, where at that concentration all the test worms died. Meanwhile, the highest survival rate after the herbicide was 200 ppm where the worm mortality was 20%. The higher the concentration of herbicide formulation given to earthworms, the higher the mortality rate and decrease in body weight.

Abstract

This research aims to obtain suitable alternative nutrients for vegetable cultivation using the Hydroponic Wick System so that the production costs of hydroponic cultivation can be cheaper and more affordable. The research was conducted in the Tebeng area, Ratu Agung Kodya Bengkulu, at an elevation of 50 meters above sea level. The research method used was a Randomized Block Design with a Factorial pattern (RAKF). The first factor had 3 levels of vegetable types: kailan (S1), caisim (S2), and pakcoy (S3). The second factor had 3 levels of nutrients: AB Mix 100% (N1), alternative 100% (N2), and ABMix 50% + alternative 50% (N3). Thus, there were 9 treatment combinations with 3 replications. The results of the research showed that the plant height, number of leaves, wet weight, and dry weight of plants using Alternative Nutrients for kailan, caisim, and pakcoy vegetables significantly influenced the use of AB Mix nutrients, Alternative Nutrients, and the mixture of both nutrients when grown using the Hydroponic Wick system. The best results were achieved using alternative nutrients. This was evident from the tallest plant height at harvest, which was 34.20 grams at 42 days after planting (HST), 16.62 leaves, 142.69 grams wet weight, and 7.60 grams dry weight. These results were significantly better compared to using other nutrients, offering a potential solution to the high costs of hydroponic cultivation due to the expensive price and limited availability of AB Mix nutrients, especially in the region.

Abstract

This research aims to determine the effect of potassium fertilizer doses on the growth and yield of watermelon plants planted in ultisol soil, and determine short-term changes in weed composition.The experiment used a Randomized Block Design (RAK) with five treatments of potassium (D) doses and three replications. The treatment doses are: Without fertilizer (control) equivalent to 0 kg/plot; A dose of 125 kg/ha is equivalent to 37.4 g/plot; A dose of 250 kg/ha is equivalent to 74.8 g/plot; A dose of 375 kg/ha is equivalent to 112.1 g/plot; A dose of 500 kg/ha is equivalent to 149.5 g/plot. The research data was analyzed using Sidik Ragam to find out whether the treatment had a real effect or an insignificant effect. If the results of the analysis have a real or very real effect, then continue with the Duncant's Multiple Range Test (DMRT) at the 5% level.This research concluded: (1) The dose of potassium fertilizer had no significant effect on plant length and fruit weight per plant but had a very significant effect on fruit weight per plot. Potassium fertilizer dose of 500 kg/ha provides the highest fruit weight per plot; (2) Potassium fertilizer doses tend to provide different weed populations and dry weights in watermelon plantings. The higher the dose of potassium fertilizer given tends to increase the weed population and weed dry weight; (3) The weed community coefficient index between mid and late weeds in watermelon planting is the same. However, the number of weed populations and biomass in the middle observation was higher than the final observation of watermelon planting.
