Abstract

Stocks are one of the investment instruments that are currently in demand because they have a greater return value than saving in a bank. It's just that investing in stocks has the risk of decreasing the value of the stock price, which can make investors lose money. Mining stocks are currently the prima donna of investors, because their value continues to rise. However, buying shares at the right time is still an obstacle, therefore a stock price prediction is needed that can help investors determine the right time to buy mining shares. The use of machine learning can be done to predict stock prices. The data used in this research is PTBA stock price data from 2017 – 2022. In this study, the Neural Network algorithm is used with hyperparameter optimization. In this study, the RMSE value was 30.634. A small RMSE value indicates that the Neural Network algorithm can be used to predict PTBA's stock price.

Abstract

The need for nutrients to support plant growth is very important, coupled with hydroponic technology, the use of nutrients is the main requirement in supporting good plant growth. Therefore, in this study the authors forecast the nutritional needs to support plant growth from time to time. The analysis used by the author is using linear regression analysis. So by using linear regression analysis, it can be known the nutritional needs in hydroponic plant growth. In determining the provision of nutrients, it is influenced by the pH of the nutrients, the height of the nutrient liquid in the reservoir, and the dissolved nutrient particles in the reservoir. Calculations are made every 4 days, within 56 days, with the type of hydroponic plant is paprika. Forecasting of nutrition is used in an Internet of Things ecosystem, so that nutrition can run automatically based on Linear Regression calculations. Forecasting in this study uses linear regression with the RMSE (Root mean square error) result of 51.47887, from these results it can be categorized as forecasting that is close to the real value

Abstract

The indonesian state has so much natural wealth that can be used to support the life of the country and its people, one of the natural wealth owned is in the tourism sector. Poso City as part of Indonesia has so much natural beauty, but the human tragedy that has occurred in Poso, leaves a very dark story, even has an impact on the memory of all Poso people, as well as people outside poso. This impact is obviously traumatizing for the Poso community, the conflict inflicts a deep and lasting trauma even though it has long passed. This research is very important to be carried out in Poso, not only because the issue of tourism is a hot topic for now and its relation to the image of the city of Poso (challenges and opportunities), but also just to bring to the surface the old story of the tragedy that has occurred, which then directs the research to identify the attitudes and traumas of tourism and tourists. But most important in the study is how researchers try to put tourism as a trauma recovery "space" that erodes negative stereotypes and restores the positive image of the city of Poso. The research method used in this study is qualitative with a case study approach and the data collection techniques that will be used in this study are observation, interview, and documentation. The data analysis carried out in this study began with reducing the data from the interview, making it verbatim, and determining the findings of the theme to be chosen for analysis. The purpose of this study was to analyze the attitudes of tourism business actors after the Poso conflict and how they recovered and rose from deep trauma and frustration.
