Abstract

One of the causes of the low productivity of sweet corn is decreased soil productivity due to the leaching of nutrients by rainwater, tillage, and continuous application of inorganic fertilizers. The function of mulching is to increase soil moisture, suppress weed growth, and prevent soil erosion to create optimal soil conditions for plant growth. This study aimed to determine the effect of organic mulching on soil fertility and the productivity of sweet corn (Zea mays saccharata Sturt). This study used a Split Plot Design consisting of two factors, Tillage (P) and Organic Mulch (M) which had 6 levels, M0 = No Mulch, M1 = Plastic Mulch, M2 = Rice Straw Mulch, M3 =Cocopeat Mulch, M4 = Sawdust Mulch, M5 = Rice Husk Mulch. The results show that the M2 treatment of Rice Straw Mulch tended to increase soil fertility and had a significant effect on the productivity of sweet corn.

Abstract

This study presents a novel approach to assist learning analysts in identifying suitable learning pathways based on historical training data through the utilization of text mining techniques. The dataset utilized in this research comprises training data from the year 2021 and the Course Development Management Program (CDMP) catalogue. The BERT 'bert-base-nli-mean-tokens' model is employed for encoding purposes. By comparing the training data names from 2021 with the CDMP catalogue using cosine similarity and dot score, valuable insights are obtained. The findings indicate that cosine similarity is a more effective measure for interpreting the data, thereby simplifying the process for learning analysts and managers in identifying appropriate learning paths for their employees. This research provides a practical solution that leverages text mining techniques to optimize the analysis and decision-making processes in learning and development domains, enabling organizations to enhance the effectiveness and efficiency of their training programs.
