<![CDATA[Background: PT Telkom Indonesia Tbk is the largest company in the telecommunications sector in Indonesia. PT Telkom's share price always rises every year, attracting investors to invest. In investing, it is very important to analyze shares in order to know the situation and condition of the shares. Objective: This research aims to predict the share price of PT Telkom Indonesia Tbk. Methods: The method used is the Autoregressive Integrated Moving Average (ARIMA)-Fuzzy Time Series Cheng hybrid method. Cheng's FTS model is able to overcome nonlinearity problems in ARIMA model residuals. In this research, the first modeling uses the ARIMA model, where the data is divided into two, namely January to November 2019 data used as training data, and December 2019 data used as testing data. Next, residual modeling was carried out with FTS Cheng. Hybrid forecasting is obtained by adding up the results of ARIMA and FTS Cheng forecasts. Result: Model evaluation is based on MAPE values and in this study the MAPE value of the ARIMA-FTS Cheng hybrid model was obtained at 1.03\% for training data and 1.09\% for testing data. Conclusion: The hybrid model has a MAPE value of less than 10\%, so it can be concluded that the ARIMA-FTS Cheng hybrid model can predict PT Telkom Indonesia Tbk stock closing price data accurately.]]>

<![CDATA[Background: Palangkaraya is a city that has a variety of natural beauty and culture. However, the tourism potential in this area is still not fully optimized and managed properly. One of the causes of this is the lack of ownership by the Government regarding the mapping of areas that have the potential to become tourist areas in Palangkaraya City. Therefore a system is needed that can assist the Government in mapping areas that have the potential to become tourist areas Objective: Develop a system that can be used to map areas that have the potential to become tourist areas. The information generated from the developed system is expected to assist the government and the private sector in increasing tourism in Palangkaraya City. Methods: The method used is the application of Location Based Service technology with a combination of Analytical Hierarchy Process and Profile Matching methods. Result: The system developed uses 10 criteria with 37 alternatives to produce information related to the sequence of tourism potential levels where the results of the sequence are then displayed on a map to provide an overview of the mapping of tourism potential areas. Conclusion: The system that has been created has succeeded in mapping areas that have tourism potential by applying LBS technology and a combination of AHP and Profile Matching methods. From this system it was found that blood with the alternative code A1 had the highest value, namely 4.295193, followed by A10 with a value of 4.156934 and so on. The test results were carried out by comparing the results of the system with the calculation results, it was found that the results were appropriate.]]>

<![CDATA[Application-based services are currently increasingly being used, one of which is thesis guidance services for final year students. The process of completing students' final assignments is sometimes difficult to monitor due to the lack of time for supervisors and students to meet. In this research, it is proposed to create an online thesis guidance service system based on an Android application. In the application that will be built, all features will be tailored to the specific needs of users, namely the needs of supervisors and students in providing online thesis guidance services. Therefore, it is proposed to design applications using the Human Centered Design (HCD) method. HCD is a method of developing software that focuses on the needs of certain user groups by conducting needs analysis directly with potential users. By using this method, it was found that the application that was built functioned very well and met user expectations, where the level of user satisfaction with the features provided was very good.]]>
