Abstract

Online learning assessment and evaluation has been widely used using the Learning Management system (LMS). However, the form of the questions is still based on multiple choice. Evaluation and form of questions in LMS need to be developed by exploring metacognitive thinking. The LMS plugin supports Essay-based questions and assessments, it's just that this plugin needs to be supported with file submissions and metacognitive assessment rubrics. Therefore, this research aims to customize and test the usability of Auto Essay File Grading (AEG) metacognitive assessment based on LMS. This study uses a quantitative descriptive approach conducted at the Faculty of Engineering, Universitas Negeri Makassar, with lecturers and students as respondents. Data were collected through the USE questionnaire and analyzed using descriptive statistics. The results of the analysis of AEG usability testing from the point of view of lecturers and students who have the highest average are a usefulness. For the lowest average of the lecturers is the ease of use and from the student, the side is the ease of learning. These results also prove that the AEG application/plugin needs improvement in terms of ease and practicality of use so that users learn how to use it faster. Recommendations for ease of use and learning are discussed and explained further, along with the improved display, answer keywords, and minimizing irrelevant menus.

Abstract

In the last few years, the terms Smart Agriculture, Smart Farming, Urban Farming, or Precision Farming have been increasingly recognized and growing rapidly. Hydroponics is one part that is currently a trend, both in industrial or household scale businesses and hobbies. One of the most important things to consider in maintaining the quality of hydroponic plant growth is the concentration of nutrients in the water. A series of studies have been conducted to improve the quality of hydroponic plants. However, the developments that have been carried out have not focused on optimal nutritional control. The previous hydroponic plant nutrition control system still used conventional methods, namely the use of a rule base with firm values ​​, and did not consider the quantity and quality of water. Therefore, this study proposes a new model for an adaptive control system for hydroponic lettuce nutrition based on the Fuzzy Logic Sugeno method using ESP32. The fuzzy logic Sugeno method is used to create a new model of the inference system for determining the amount of nutrient dosage based on supporting data obtained from sensors installed on hydroponic growing media. Compared with the conventional method, the resulting test results show that the proposed method can adapt the amount of added nutrients, provide optimal nutrient addition output, and prevent excess nutrient additions that can potentially accumulate toxic ions in water that degrade water quality.
