Abstract

This study aims to perform modeling and determine the factors that significantly and not significantly influence the completion of the thesis. The analysis used is the path analysis of the decomposition method. The data used is primary data by distributing questionnaires. Based on the results of the analysis that has been done, the path analysis model for the factors that influence the completion of the thesis are: The factors that significantly effect are facilities (), selection of specialization courses (), and selection of courses (). While lecturer factor () and motivation factor () have no effect. Supporting facilities factor and selection of supporting courses factor only directly affect the completion of minithesis. While the selection of specialization courses also has indirect effect to the completionof the thesis.

Abstract

In today's developing era, quite a few schools still have limitations or lack of learning media. So technology is needed to support the learning process so that it is easier for students to learn both online and offline. This research aims to create and add Augmented Reality-based learning media at SMA Negeri 1 Plampang. The learning media created is a chemistry practical learning application using the Android platform which will be implemented in the chemistry textbook for class XMIPA students at SMA Negeri 1 Plampang. Augmented Reality technology makes it possible to combine the virtual world and the real world in real time. So it will be able to provide a real learning experience. By applying Augmented Reality to the Chemistry textbook, students will be able to get to know the chemistry practical tools displayed through the application without needing to look directly into the chemistry laboratory. The research method used is the ADDIE method which consists of analysis, design, development, implementation and evaluation stages. This method will produce output in the form of an Android-based application that uses Augmented Reality technology to display 3D objects for chemistry practical tools. Based on the results of the questionnaire or questionnaire that was given to respondents, the result was that the application that had been created was feasible and could be used as a learning medium that would be used at SMA Negeri 1 Plampang in the Chemistry subject class X-IPA CHAPTER 1

Abstract

The price of the paddy has significant fluctuations as BPS mentioned that the average price of dry  paddy harvested at the farmer level decreased in February 2022 by 3.2% from January 2022. Hence, crop industry businesses continue to face significant uncertainty risk. The purpose of this study is to discuss the use of the Fuzzy Time Series Model Lee for predicting future paddy prices in order to calculate crop insurance premium using Black Scholes model with cash or nothing put option approach. This is because crop industry is one of the agricultural products that Indonesia is capable of producing in large quantities. As a result, crop insurance should be purchased by farmers to protect against crop yield losses. Aside from that, the price of paddy fluctuates significantly. Therefore to reduce the loss of revenue from reductions in decreasing of crop yield or even crop failure, it needs to provide the insurance based on the paddy prices to protect the paddy prices itself from the large fluctuations at the farmer level. Based on the analysis of this study, generates result for January 2022, February 2022, and March 2022 are 4547.41, 4547.41, and 4701.62 respectively. With the accuracy level is 0.05%. Therefore, the insurance premiums based on the prediction result is 2,775,579. The implication or benefit of this thesis is for the other parties such as farmer

Abstract

The competition of two populations model that represented in an ordinary differential equations system. This model describes about the competition of two population in general that is consist of the interspesies competition and the intraspesies competition. In ecology, the population dynamic is closely related to population growth, equilibrium, and stability. Equilibrium is represented by a point called the equilibrium point or fixed point. By analyzing the stability around the fixed point, it can be seen the carrying capacity of a system, which mean the optimal number of individual that can be supported by the environment. According to the analysis of the model obtained 4 fixed points, three of them are unstable and the other else is stable. The orbit of the system around fixed point visualized using software. The behavior orbit around fixed point of the model will move away from the unstable fixed point and move closer to the stable fixed point.
