Mung beans are plants that have high economic value but the production of mung beans in Indonesia is still low. Dung serves to provide nutrients for plants, improve soil structure, and retain water in the soil. MOL (local microorganisms) banana corm has a number of microorganisms that can help plants absorb nutrients found in the soil. The purpose of this study was to determine the effect of the interaction between types of dung (dung) and banana corm local micro organization (MOL) on the growth and yield of mung beans Vima 2 and to determine the type of dung and the MOL dose of banana corm that was best for the growth and yield of mung bean plants. The method used in this study was a randomized block design with 2 factors and 3 replications. The first factor is the type of dung = no dung (j0), chicken dung (dung) (jl), goat dung (j2) and cow dung (j3). The second factor was the MOL dose of banana weevil, 0 ml plant-1 (m0), 50 ml plant-1 (m1) and 100 ml plant-1 (m2). The results showed that the application of dung and the MOL dose of banana corm did not show any interaction, but there was an independent influence by the type of dung on the parameters of plant height, number of pods per plant, number of seeds per plant, weight of seeds planted, and harvest index, so that the type of dung that gives optimum results in mung bean cultivation is chicken dung.
This study aims to find a strategy for developing learning models through Javanese dolanan songs as learning materials and to find out and describe the meaning contained in the lyrics of the song in strengthening the values of character education. The research method includes observation, FGD, interviews, documentation with purposive sampling. By using an analytical model (Miles & Huberman, 1992), starting from data reduction and data presentation continuously until a conclusion is drawn; Javanese dolanan songs that are applied in elementary schools will strengthen Javanese culture, shape the personality of students getting scores in the range of 62-70, an average of 30% to 40% means that teachers understand Javanese dolanan songs on average, understanding with a touch of the art of educating while playing, after class hours the teacher stimulates children's motor skills through learning strategies through music an average of 40%, dancing and singing Javanese dolanan songs, 20-30% using gamelan media to improve students' motor skills, increasing selfconfidence and abilities with the role-playing method in Javanese dolanan music, 10% through the use of natural environment media. Suggestions so that Javanese songs strengthen character education values for elementary school students can be optimal. It needs to be included in the local content curriculum and mandatory for all teachers and students to further improve their activities.
Environmentally friendly polymer concrete by utilizing waste has been widely developed, one of which is sugarcane fiber waste and egg shell powder. Utilization of this waste is not optimal, for that by being used as a filler in polymer concrete, it is expected that it will have a higher economic value. This study was to determine the composition of the epoxy resin binder and the mechanical characteristics of polymer concrete fabricated using sugarcane fiber waste with an epoxy resin adhesive. Variations in composition made of sand, egg shells (1 : 1) or (50 g : 50g), bagasse waste 0%, 1%, 2%, 3%, 4% and 5% of the total weight. Epoxy resin composition variation of 20%, 25% and 30% of the total weight of sand and egg shells. Then carried out the characteristics in the form of density test, water absorption, porosity, compressive strength and tensile strength. From the test results, the characteristics of polymer concrete have optimum values, namely density (1.76 g/cm3), water absorption (4.04%), porosity (5,252%), compressive strength (26,27 MPa), tensile strength (4,06 MPa). Of the three samples, the best in the A5 sample with a sound absorption coefficient of 0.237 met the requirements of ISO and ASTM C.384.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
