Abstract

Coffee waste contains a large amount of nutrients, making it a potential raw material for compost fertilizer. The nutrients contained in coffee waste include N, P, K, Mg, and Ca. Utilization of coffee waste as compost requires bioactivators to accelerate the decomposition process. This study aims to determine the difference in compost quality from coffee waste by using bioactivators in the form of local microorganisms (LMO) of cassava tapai. This study was conducted from April to May 2023 at the greenhouse of LPP Polytechnic Yogyakarta, consisting of two stages: making the LMO and making the compost. Cassava tapai LMO was prepared as a treatment for composting coffee waste. Each treatment was repeated three times. After that, the fermentation results in the form of compost were tested, then the results were compared with the standards of the Decree of the Minister of Agriculture No. 261/KPTS/SR.310/M/4/2019 on the minimum technical requirements for organic fertilizers, biological fertilizers, and soil conditioners. The results reveal that the provision of cassava tapai LMO bioactivator affected the quality of coffee waste compost produced. The quality of composts produced from control, cassava tapai LMO of 90 ml, and EM-4 treatment does not meet the standards of the Decree of the Minister of Agriculture in the parameter of chemical properties, namely the C/N ratio. The quality of compost produced from cassava tapai LMO of 120 ml meets the standards of the Decree of the Minister of Agriculture and SNI 2004 in all parameters of physical properties, chemical properties, and nutrient content.

Abstract

This research aims to identify and analyze the influence of Kiai leadership and Pesantren culture on quality and competitiveness as mediating variables. The quantitative research method employs an explanatory research approach with a survey method. The questionnaire was designed based on the research variables, which include leadership, motivation, organizational culture, employee work discipline, and organizational commitment. Data was collected from 97 employees through random sampling. The data analysis utilized multiple regression analysis and the Sobel test. The results indicate that Kiai leadership significantly influences quality, meaning that the higher the Kiai leadership, the higher the quality; Pesantren culture significantly influences quality; Kiai leadership significantly influences competitiveness; Pesantren culture significantly influences competitiveness; competitiveness significantly influences quality, meaning that the higher the competitiveness, the higher the quality. Competitiveness can mediate the relationship between Kiai leadership and quality, indicating that an increase in competitiveness impacts the enhancement of Kiai leadership, thereby improving quality; and also acts as a mediating variable between Pesantren culture and quality, indicating that an increase in competitiveness enhances Pesantren culture, which in turn improves quality.

Abstract

This research aims to determine and analyze the influence of leadership, motivation, and organizational culture on employee work discipline with organizational commitment as an intervening variable at MAN Tulungagung, East Java, Indonesia. The research method is quantitative with an explanatory research approach with a survey approach. Research data was taken from 79 teachers who were the sample for this research. This research analyzes data using multiple regression analysis. The results of the research show that 1) leadership has a significant effect on organizational commitment; 2) Organizational culture has a significant effect on organizational commitment; 3) Leadership has a significant effect on work discipline; 4) Organizational culture has a significant effect on work discipline; 5) Leadership has an indirect effect on work discipline through organizational commitment, which means there is a mediating influence. So, organizational commitment can mediate between organizational culture and work discipline. Organizational culture has an indirect effect on work discipline through organizational commitment, which means there is no mediating influence. So, organizational commitment cannot be a mediating variable between organizational culture and work discipline.
