This research was motivated by the lack of data on the types of lichen in the Teluk Wang Sakti Area and the research on the types of lichen in Merangin is very lacking. Lichen can be found in the Teluk Wang Sakti Area because it has natural conditions that support lichen growth and development. The purpose of this research was to find out and describe the types of lichen in Teluk Wang Sakti. This type of research used a qualitative descriptive research. The research method used was the method of reconassance (roaming). The location of the research was conducted in Teluk Wang Sakti and on the edge of Jl. Lintas Bangko-Kerinci. Lichen found in Teluk Wang Sakti is 60 species including 11 genera and 10 families : Parmotrema and Parmelia (Family Parmeliaceae),Graphis (Family Graphidaceae), Dichosporidium (Family Rosellaceae), Arthonia (Family Arthoniaceae), Dirinaria (Family Dirinariaceae), Cryptothecia (Family Cryptotheciaceae), Lecanora (Family Lecanoraceae), Megalospora (Family Megalosporaceae), Lepraria (Family Leprariaceae) and Caloplaca (Family Caloplacaceae). Teluk Wang Sakti Area has an average temperature of 27.9oC and 82.3% humidity. While on the edge of Jl. Bangko-Kerinci crossing around the factory has an average temperature of 42.2oC and humidity of 36%. The Teluk Wang Sakti Area is indicated to have better air quality compared to the edge of Jl. Bangko-Kerinci crossing around the factory, due to the lack of types of lichen found and the presence of Parmotrema sp. type of lichen used as a bioindicator of air pollution.

The lack of utilization of waxy banana peel waste in Merangin District is a source of environmental pollution. Wax banana peel waste has the potential as a liquid organic fertilizer. This study aims to determine the effect of giving liquid organic fertilizer from wax banana peel waste on the growth of red spinach plants and to determine the dose of liquid organic fertilizer from waxy banana peel waste which gives the best results for the growth of red spinach plants. The study used a Completely Randomized Design (CRD) of one factor, consisting of 6 treatments namely P0 (0 ml / control), P1 (10 ml), P2 (20 ml), P3 (30 ml), P4 (40 ml) and P5 (50 ml) with 4 repetitions. The parameters of this study were plant height, number of leaves, leaf surface area and root length. Data were analyzed using variance analysis and continued with Duncan test 5%. The results showed that liquid organic fertilizer of wax banana peel waste had a significant effect on the number of leaves, but did not give effect to plant height, leaf surface area and root length of red spinach. Liquid organic fertilizer of wax banana peel waste 20 ml dose gives the best results on the number of red spinach plant leaves.

This research was motivated by the problem of Babadotan plant weeds in oil palm plantations in Kabupaten Merangin . Babadotan plant has the potential as a liquid organic fertilizer. This research aims to determine the effect of liquid organic fertilizer from babadotan plants on the growth of pakcoy. This study used a one-factor completely randomized design (CRD), consisting of 6 treatments, namely P0 (0%), PI (10%), P2 (15%), P3 (20%), P4 (25%), P5 (30 %), with 4 repetitions. The growth parameters observed were the number of leaves, leaves surface area, plant height, and root length. Data were analyzed using analysis of variance and continued with the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the liquid organic fertilizer of babadotan plant had a very significant effect on leaf surface area, had a significant effect on root length, but did not significantly influence the growth of stem height and number of pakcoy leaves. Liquid organic fertilizer from babadotan plants with a concentration of 20% gives the highest average in each treatment for each measurement parameter. However, the best POC concentration from the results of the Duncan test showed that the treatment that had a significant effect on the leaf surface area and root length of the pakcoy plant was a concentration of 0% or without treatment.
