Abstract

Corn cobs are agricultural waste that is easy to obtain because the waste has not been optimally utilized. The waste has the potential to be used as feed for livestock, but has a low quality. The purpose of this study was to determine the characteristics, protein content and crude fiber of corn cobs with different fermentation times. The research method used a completely randomized design (CRD), with five treatments. The length of fermentation consisted of 0.5.10.15 and 20 days and was repeated 4 times so that there were 20 experimental units. The results of the study The length of fermentation on corn cobs can increase the characteristic value, increase protein content and can reduce the crude fiber content of corn cobs so that it is easier for livestock to digest.

Abstract

This study aims to analyze the role of school principals’ leadership in motivating teachers and to examine how work culture contributes to teacher performance at SMKN 1 Banjarbaru and SMKN 3 Banjarbaru. Effective leadership and a healthy work culture are considered crucial elements in improving the quality of education as well as teacher performance. The research employed a descriptive quantitative method, with interviews as the primary data collection instrument. The participants of this study consisted of principals and teachers from both schools. Data analysis was carried out using the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The findings reveal a significant influence of principal leadership on teacher motivation. Principals who applied transformational leadership—characterized by providing support, recognition, and involving teachers in decision-making—were proven to enhance teachers’ motivation. Furthermore, a positive work culture, reflected in teamwork, effective communication, and a supportive work environment, was also found to have a strong correlation with improved teacher performance. In conclusion, the study highlights that effective leadership and a conducive work culture significantly contribute to teacher performance at SMKN 1 and SMKN 3 Banjarbaru. The recommendations include encouraging principals to continuously develop leadership skills, design more targeted motivation programs, and foster a positive work climate. These efforts are expected to further enhance teacher performance, thereby positively impacting the overall quality of education in SMKN Banjarbaru.
