Abstract

C. kyllingia is an annual weed that can cause problems because it can reduce the quantity and quality of cultivated plant production, so this weed needs to be controlled. Weed control with synthetic herbicides is currently more popular because its effectiveness can be seen more quickly. However, if synthetic herbicides are used for a long period of time, they will affect soil conditions. Therefore, an alternative weed control using liquid smoke from empty oil palm fruit bunches (TKKS) is needed. The research aims to determine the potential of TKKS liquid smoke in controlling the growth of sedge weed (C. kyllingia). The design used a 1 factor Completely Randomized Design consisting of 5 treatments and 5 replications with liquid smoke concentrations of 0%, 8.3%, 16.6%, 25% and 33.3%. Research shows that TKKS liquid smoke has the potential to be used as a natural herbicide because it has an effect on suppressing the growth of the C. kyllingia weed. The best concentration that can suppress weed growth is 33.3% liquid smoke.

Abstract

Shallots (Allium ascalonicum L.) from the Lilyceae family are annual horticultural plants. The aim of this research is to determine the effect of the application of organic fertilizer plus on the diversity of arthropods in shallot plants in peatlands. The method used in this research was a one-factor Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. Data from arthropod identification results are grouped based on order and family which are presented in tabular form. Then an analysis was carried out using diversity indices, species richness and species evenness. The results of the research show that the most dominant arthropods are the predator group. The results also show that the level of arthropod species diversity is moderate, the level of arthropod species richness is low, the level of evenness of arthropod species shows an unstable distribution. The most dominant group of arthropods is the predator group and the results of the LSD analysis test at the 5% level showed a real influence on the diversity of arthropods in shallot plants in peatlands where organic fertilizer plus 125 g/hole was applied with an average of 48.40 individuals.
