Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan tanaman enceng gondok dalam mengurangi kandungan tebukonazol pada air limbah dan untuk menemukan konsentrasi maksimal tebukonazol dalam air limbah yang dapat diolah dengan metode fitoremediasi menggunakan tanaman enceng gondok. Analisis kemampuan tanaman enceng gondok meremediasi tebukonazol dengan penyiapan reaktor sebagai media tanam dengan konsentrasi tebukonazol yang berbeda yakni 1,0 ppm, 1,5 ppm dan 2,0 ppm. Masing-masing reaktor ditanami enceng gondok dengan jumlah yang sama dan kriteria yang sama pula. Dalam 2 minggu pengamatan tersebut diperoleh data tentang keberhasilan tanaman enceng gondok dalam meremediasi tebukonazol yakni pada masing-masing reaktor tersebut secara keadaan fisiologis tanaman mengalami kelayuan yang disebabkan adanya proses fitoremediasi oleh enceng gondok. Selain itu, didapatkan data HPLC yg menunjukkan penurunan konsentrasi tebukonazol dengan diketahui persentase removalnya sebesar 15,3 %.

Abstract

Soybean as a protein sources can fill the needs of public’s food increasily but the production in this country is still low. Therefore, cultivation efforts are needed to improve the growth and development of soybean plants. Some factors that are sufficient to influence the plant growth process are nutrient supply, water availability, sunlight, air temperature, oxygen and growth regulators. Plant Growth Regulator (PGR) that can be used is moringa leaves as a source of cytokinins. Cytokinin serves stimulating cell division, postpone the process of aging plants, and spur growth budding. This study aims to determine the effect of giving plant growth organic made by moringa leaves with 2 control, which are negative control (0%) and positive control (cytokinin synthetic solution) and 3 treatment at concentration of P1 (10%), P2 (20%), P3 (30%) to increase the growth soy plants and to know the concentration optimally of any treatment given. This research using the completely randomized design (CRD) with 5 treatment and 5 replicate. The results were analyzed using the ANOVA test followed by the LSD/BNT test and the Duncan test. The results showed that the application of organic PGR made from Moringa leaves had a significant effect (P <0.05) on growth (plant height and number of leaves) and chlorophyll content in soybean plants had optimal concentrations at 30% concentration. Keywords: moringa leaves, cytokinin, soybean plants, plant growth regulator.

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.

Abstract

Maize (Zea mays L.) is an important agricultural commodity in Indonesia, yet its production is often hindered by pathogenic infections, notably Curvularia sp., the causal agent of leaf spot disease. This study aimed to evaluate the antagonistic activity of Pseudomonas fluorescens against Curvularia sp. under in vitro conditions. The pathogenic fungus was isolated from infected maize leaves, while P. fluorescens was isolated from soil samples and identified through biochemical tests and pigment production on King’s B medium. Observations revealed that P. fluorescens produces fluorescent pigments, is an obligate saprophyte, and does not induce soft rot in potato tissue. Antagonism assays showed that the growth of Curvularia sp. was inhibited in the presence of P. fluorescens, as evidenced by fungal hyphae growing away from the bacterial colony. This inhibitory effect is likely due to antifungal secondary metabolites produced by P. fluorescens, including antibiotics, hydrogen cyanide, siderophores, and extracellular enzymes such as chitinase and cellulase, which degrade fungal cell walls. These findings suggest that P. fluorescens holds promise as a biocontrol agent for managing leaf spot disease in maize.   Keywords: Zea mays, Pseudomonas fluorescens, Curvularia sp., antagonism, leaf spot disease
