Abstract

This research aims to determine the characterization of the rhizosphere bacteria of the roots of Mimosa pudica in its contribution as a decomposer agent that will be used in making of biourine. The research held in June-August 2023, was carried out in several stages, like the preparation stage, the bacterial isolation stage, and observing the macroscopic and microscopic characteristics of the bacteria. The results of the macroscopic and microscopic characteristics obtained during the observations showed that the isolates in the MOL of the roots of Mimosa pudica resembled the characteristics of bacteria from the genera Bacillus (MAP6), Rhizobium (MAP4), Pseudomonas (MAP1, MAP2, MAP3, MAP5, and MAP8), and Klebsiella (MAP7). These four genera are types of soil bacteria that are capable of producing plant hormones that can speed up the process of nutrients absorption and breakdown of organic material in the soil optimally.

Abstract

Teacher education plays a strategic role in preparing future educators to address global sustainability challenges articulated in the Sustainable Development Goals (SDGs). This study aims to examine how Biology Teacher Education curricula in Indonesia align with the SDGs through an analysis of Program Learning Outcomes (PLOs). A qualitative case study design was employed using document analysis of PLOs from Biology Education programs at three public universities ranked among the top 20 institutions in Indonesia according to the Scimago Institutions Rankings (SIR) 2025. A benchmarking framework was applied to assess the extent to which PLO indicators support the achievement of the 17 SDGs. The findings reveal varying degrees of alignment across institutions. Research competencies, scientific problem-solving skills, and technology integration demonstrate the strongest alignment with SDG targets, while environmental knowledge and laboratory skills particularly support goals related to quality education, innovation, and environmental sustainability. However, character- and religiosity-oriented outcomes do not explicitly correspond to specific SDG targets, and overall integration remains implicit rather than systematically embedded within the curriculum. These results indicate the need for more explicit curriculum mapping to ensure coherent and comprehensive integration of SDG dimensions in Biology Teacher Education programs.

Abstract

This study aims to determine the manufacturing process and the quality of liquid organic fertilizer made from vegetable waste from Pasar Baru, Tuban Regency. Liquid organic fertilizer is done as a solution to the amount of vegetable waste which is the most waste produced by Pasar Baru in Tuban Regency with the amount reaching 2 tons / day. This large amount of vegetable waste will cause environmental problems if not handled and treated properly. The method used in making liquid organic fertilizer is semi anaerobic fermentation using drum composter with the addition of EM-4 bioactivator. The quality of liquid organic fertilizer will be seen based on the physical properties and the results of the analysis of macro nutrient content and adjusted to SNI determined by Permentan No. 70 Th. 2011. The results of the analysis showed that physical properties pH and temperature are fullfill the standard of SNI Permentan No.70 Th. 2011. But for the content of macro elements of C-organic, N, P, and K total are not fullfill the standard.

Abstract

Urine is a liquid waste of cattle farming that can be used as raw material for producing liquid organic fertilizer. This study aims to determine the effect of the process of obtaining urine waste in cattle farms on the quality of liquid organic fertilizer. The measured parameters include N, P, K, pH, organic-C, and bacterial contamination, in accordance with the Indonesian Ministry of Agriculture Regulation No. 261 of 2019. The method used in this research is fermentation with EM4 decomposer for 30 days. The results of the one-way ANOVA test showed significant differences in pH, organic-C, N, P, and K between B1 and B2, with higher values of pH, organic-C, N, and P in liquid organic fertilizer made from cattle urine mixed with manure. Meanwhile, the K value was higher in liquid organic fertilizer made from pure urine without manure.
