The Influence of Biosaka on the Growth and Yield of Rice Plants in a Sustainable Agricultural System Viewed from Philosophy of Tamansiswa in Argorejo Village, Bantul Regency, Indonesia

Abstract

This research aims to see the effect of biosaka elicitors on the growth and yield of rice plants in a sustainable agricultural system in terms of the Tamansiswa philosophy. In this research, Logawa and IPB 3S rice varieties were used. This research was carried out at Argorejo Village, Sedayu District, Bantul Regency, Yogyakarta, Indonesia. This research is a combination of scientific research and literature study. The data obtained were analyzed statistically using ANOVA source of diversity analysis and the Duncan Multiple Range Test with a level of 5%. After that the results were reviewed philosophically based on Tamansiswa's noble values. The results of this research were that in the research on the Logawa rice variety, the variable number of tillers with sembung extract treatment had a significantly different effect on the purslane treatment, while on the variable grain weight per hectare with the kirinyuh extract treatment it had a significantly different effect on the treatment without biosaka (control). In research on the IPB 3S rice variety, the application of biosaka with a combination of plant growth promoting rhizobacteria in the treatment with a biosaka dose of 43 l/ha was able to encourage plant height growth and the treatment with a biosaka dose of 86 l/ha inhibited plant height growth. The biosaka treatment dose of 64 l/ha was able to stimulate an increase in the physiological response of rice plants, thereby increasing the number of tillers, number of panicles and grain production per hectare. Philosophically, the spirit of "land of harmony" from biosaka is in line with Tamansiswa's philosophy of "natural nature" and "human living nature is rounded living nature" which can be used as a guide for human life and the natural surroundings, in this case plants, animals and the biological environment where humans according to their nature can live in harmony with their natural environment.
