Abstract

This study investigates the role of user experience and task type on Human-Computer Trust in the ChatGPT system. The method used in this research is an experiment where respondents are asked to do mathematics, descriptive, translation, and programming tasks on the ChatGPT application. After completing each task given, respondents were asked to fill out the trust questionnaire that had been prepared. Respondents in this study were divided into two categories: novice and expert. The total number of respondents in this study was 32 respondents. The result of this research is that the level of user experience significantly influences human-computer trust in the ChatGPT application in Task 1, Task 2, Task 3, and Task 4. However, there is no significant influence from differences in the types of tasks on human-computer trust in the ChatGPT application.

Abstract

It is necessary to give concentrated attention to the issue of stunting by implementing appropriate nutrition initiatives to prevent stunted physical and mental development. Optimal food availability is one effective strategy for preventing it. However, it often disregards preferences that guarantee pleasure, dietary diversity, and compatibility with individual tastes. In this paper, we show a two-step multi-criteria decision model. The AHP is used to figure out the criteria weights, and the TOPSIS method ranks food basket options based on how close they are to the ideal solution. The efficacy of our strategy was subsequently evaluated in Balikpapan, a prominent urban center in Indonesia grappling with the issue of stunting. The evaluation's findings were as follows: nutritional value (27%) was the most significant factor, knowledge of the food ingredients (18%), variety of foods made from the food ingredients (17%), ease of preparation, cooking, and storage (15%), cost (12%), and child preference (11%). The findings indicated that food basket 3, priced at Rp209,857 and yielding 1,854.96 kcal, consisted of rice weighing 3.63 kg, duck egg weighing 1.16 kg, milkfish weighing 0.65 kg, tuna weighing 0.06 kg, cauliflower weighing 0.17 kg, kale weighing 3.46 kg, and dragon fruit weighing 1.87 kg. In addition to nutrition and cost, this study highlights that considering preferences can enhance the appeal of food baskets.

Abstract

Manual work activities are more dependent on the operator's ability which still makes frequent Errors. One of the mistakes that occurs is due to human negligence or human Error. Human Error in manual work can result in work accidents. Even if human Error occurs frequently, it can result in a decrease in the efficiency and effectiveness of the company. Lathe activities at PT. C still uses the machine manually. Lathe work activities include the process of installing the lathe tool, picking up the workpiece, setting up the workpiece and the turning process. However, in these activities, there are still many human Errors that occur so that they affect the production of lathes. So it is necessary to improve operator performance in order to reduce human Error. For this reason, it is necessary to identify activities that have the potential for human Error. Work activities are broken down into task levels. Task levels are used as inputs to identify and analyze human Error qualitatively. This method is known as the SHERPA method. This study aims to find out the type of Error in each sub-task of the lathe process and provide recommendations to reduce the human Error that occurs. This research involved all lathe operators at PT. C. and validity is carried out to practitioners to produce consensus. The results of human Error analysis using the SHERPA method found three types of human Errors in the lathe process, action Error, selection Error and information communication Error. So, to reduce the prediction of Errors, it is recommended to train operators, relayout the production floor, increase K3 awareness, increase accuracy and comprehensive communication.
