Abstract

This research aims to be an initial study of collecting information about students' low interest in learning history by applying the Small Group Discussion learning method to learning History in Vocational High Schools (SMK). This research is a type of Classroom Action Research (CAR) using two cycles, namely Cycle I and Cycle II, this Classroom Action Research is a Quantitative Research. The results found in this study were that the majority of students with a lack of interest in learning history in Class X Motorcycle Engineering, many students thought that learning history was boring due to the use of learning methods that were less interesting, less interactive, and did not involve students directly in use of learning methods. That's why an innovation is needed in the form of a history learning method. The Small Group Discussion Method is recommended for history teachers as a method that can be a solution to the problems raised so that learning history is expected to be more enjoyable learning and the goals of learning history can be fulfilled.

Abstract

Consumption of sweet corn has increased from 2021 to 2024. To meet the growing market demand, sweet corn production must be carried out in a sustainable, economical, efficient, and environmentally friendly manner. The use of a combination of sludge, rice husk charcoal, compost, and inorganic fertilizer was tested to enhance corn plant growth and productivity. The study was conducted at the Cikabayan Experimental Farm, IPB University, using a Randomized Complete Block Design (RCBD) with five treatment levels and three replications. The results showed that treatment S2H1 (75% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) exhibited the best vegetative and generative growth (stem diameter, number of leaves, ear length, biomass weight per plot, and ear weight per plot). The S1H1 treatment (100% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) showed improved biological and chemical soil quality (pH, organic carbon, total nitrogen, total phosphorus, and base saturation). All treatments resulted in an R/C ratio above 1, indicating economically viable potential. The results indicate demonstrate that the combined use of sludge and organic materials allows NPK fertilizer inputs to be reduced by 25%, supporting sustainable agriculture.
