Abstract

Composting organic waste is significantly gaining attention as a sustainable and environmentally friendly material. This is because the use of microorganisms or microbial consortia in the composting process can enhance the quality of compost. Therefore, this study aimed to examine the impact of microbial consortia on cow manure composting efficiency and nutrient content. The experiment was conducted at the Polinela Organic Farm, Department of Food Crop Cultivation. A randomized block design was used with multiple treatments combining fresh cow manure and microbial inoculants, including catalyst, Bacillus, and Trichoderma. The parameters evaluated were the effects of water content, pH, temperature fluctuations, and macronutrient levels on composting, including nitrogen, phosphorus, and potassium. The results showed that microbial consortia significantly improved composting parameters such as moisture retention and temperature as a function of higher doses?of the inoculum. The highest total nitrogen (3.6%) and potassium (1.67%) content were obtained from Trichoderma treatment,?while the highest phosphorus (0.47%) content was obtained from Bacillus treatment. This?implied that microbial consortia could improve the quality and availability of composted nutrients in addition to the effectiveness of agricultural waste management and soil fertility practices. However, more research should be conducted?to determine the optimal microbial mixtures for various conditions of composting and the quality of the best compost produced.

Abstract

In the last few decades, there has been numerous studies on the effect of organizational culture to increase work performance, as well as organizational citizen behavior to increase effectiveness of the organization. The performance of teacher is heavily influenced by several factors such as motivation, leadership, organizational culture, organizational citizen behavior and others. This research was aimed to test the effect of organizational culture to State Madrasa teacher performance in Pesawaran Regency. This research used quantitative design. The data were collected through questionnaire shared via Google Forms to 148 respondents from the total of 222 people. The result showed that variable of organizational culture positively affected teacher performance. Coefficient of determination was 0.493 or 49.3% for the variable of organizational culture was influenced by other factors that were not studied in this research. Based on the partial test result, the variable on organizational culture had the significant value of 0.029 < 0.05

Abstract

The decrease in soil fertility due to over use of chemical fertilizers encourages the need to increase farmer awareness in utilizing more environmentally friendly nutrient sources. One alternative used in this study is humic acid in powder form. The study aims to determine the effect of humic acid on the growth and yield of peanut (Arachis hypogaea L.) variety Talam 1. The study was conducted from November 2023 to January 2024 at the Polinela Organic Farm, Lampung State Polytechnic. The parameters observed included plant height, number of branches, chlorophyll content, leaf width, and leaf length; as well as harvest parameters such as pod weight, number of empty pods, and filled pods. The study used a one-factor Randomized Complete Block Design (RCBD) with a comparative treatment of humic acid doses to reduce the use of inorganic NPK fertilizers. The results showed that the height of peanut plants of Talam 1 variety at the age of 1 WAP and 5 WAP did not differ significantly in various applications of humic acid in powder form. The use of humic acid has the potential to increase pod weight per plant in the P2 treatment by 30% from the control and 18.7% from the recommended NPK dose treatment. Humic acid in powder form can be an alternative as an environmentally friendly soil conditioner to support the growth and production of peanuts.
