Abstract

Fertilization is one of the important activities in the maintenance of soybean plants to obtain optimal growth and production. Soybeans really need nutrients N, P, and K to meet the needs of growth, flower formation and pod filling. The research was to determine the effect of liquid organic fertilizer from lamtoro leaves with the addition of rice husk charcoal media on the yield of the number of pods and pod weight of soybean plants. There were 5 treatments, namely negative control (0%), positive control (inorganic fertilizers), A1 (10%), A2 (20%), A3 (30%) in increasing the growth of soybean plants. The study used CRD with 5 treatments and 5 replications. The statistical test used the ANOVA test and the LSD / LSD test, then the Duncan test was performed. The results of the study showed that the administration of POC of lamtoro leaves and rice husk charcoal had a significant effect (P <0.05) on the yield (number of pods and pod weight) of soybean plants with an optimal concentration of 30%. Keywords: rice husk charcoal, leaf of lamtoro, liquid organic fertilizer, soybean

Abstract

The low soybean production is caused by many limiting factors, including low soil fertility. This is influenced by the use of chemical fertilizers which is a trend among farmers. Therefore, to overcome the above problems is to utilize pineapple peel waste as a bio-activator and the addition of coconut shell biochar as a medium. This study aims to determine the effect of various concentrations of bioactivator waste from pineapple peels on growth, total chlorophyll content and soybean production. The method used is an experimental method carried out at the Green House of the Faculty of Science and Technology, Universitas PGRI Adi Buana Surabaya. The design used was a factorial design (6x5) arranged in a completely randomized design (CRD) consisting of 6 treatments. Treatment 1 was negative control (0%), treatment 2 positive control (EM4), treatment 3 bioactivators 10%, treatment 4 bioactivators 20%, treatment 5 bioactivators 30%, treatment 6 bioactivators 40%. Each treatment was repeated 5 times so that 30 experimental pots were needed. The results showed a significant effect on production at a concentration of 30%. Keywords : Soybean (Gycine max (L.) Merrill), Pineapple Skin Bioactivator, Coconut Shell Biochar

Abstract

The purpose of this study was to determine the value of the index of biodiversity and the value of the important index of medicinal plants that exist in the protected forest of RPH Sekar Malang. This study used the plot line method and was carried out in stages, namely sampling, determining the location path that had been surveyed and making measuring plots consisting of 8 plots with a distance of 100 m between plots with a plot size of 20m x 20m. The research data were analyzed using the diversity value index, vegetation analysis and descriptive utilization. Based on the results of the identification and determination of potential medicinal plants, 8 species of medicinal plants were found. The total number for the diversity value index is 1. This indicates that the medicinal plant diversity index in the RPH Sekar protected forest area is in the moderate category. The importance value index for the seedling category showed the highest yield in Piper aduncum of 20.167, the stake category was Centella asiatica with the highest score of 2.899 and for the pole and tree category the largest was shown in the same species, Dendrocnide stimulant with a pole value of 6.771 and a tree value of 13.15. Keywords; Diversity, Protected Forest, Medicinal Plants

Abstract

This study aims to determine the diversity of medicinal plants on the Mount Pundak hiking trail. This research is quantitative descriptive research and data collection for this study used the plot method with a total of 8 plots at post 1 and 2 on the hiking trail with a size of 2m x 2m in each plot. Based on the results of observing the forest area of ​​the Mount Pundak hiking trail, there are 10 plant species in post 1 and 12 plant species in post 2. The total types of undergrowth that have medicinal potential are 16 types of data. This finding is based on a literature study on the analysis of medicinal plants. The species diversity index (H') in post 1 is 1.4530 and in post 2 (H') is 1.602, this shows that the diversity of medicinal plant species in the forest of Mount Pundak is moderate.
