Abstract

The increase in patients that occurs every month needs to be considered by every hospital, be it private hospitals or government hospitals. With the predictive value of the number of patients for each month. It is hoped that it can help hospital management, in making decisions to improve patient service facilities, especially in inpatient installations. In this study, the forecasting method used is Triple Exponential Smoothing, because this method is quite simple and also has advantages. The triple exponential smoothing method can adjust the trend of changes and seasonal components. The research was conducted at GMIM Siloam Sonder General Hospital, by taking samples in the form of data on the number of patients for the last 3 years using excel format. From the results of the analysis carried out, the forecast results obtained for the next 3 years are an increase seen from the increase in the total number of patients each year. The forecast value obtained is classified into high-accuracy forecasting because it has a MAPE value ≤ of 10%.

Abstract

The education sector is one of the areas that has felt the major impact of the Covid-19 pandemic. The impact that arises is teaching and learning process must be carried out from home using the online learning method. This teaching and learning method raises a variety of responses from students. This is what makes researchers analyze these views, both in the form of positive opinions or negative opinions. The analysis process is carried out by applying sentiment analysis or opinion mining from the comment on Facebook, text mining is processed using the prepocessing method, labeled it to positive and negative. Based on the available data, a classification process is carried out using the K-Nearest Neighbors algorithm. Rapid Miner is used to experiment text data with the KNN algorithm in order to find the value of accuracy, precision and recall. From the results of research, it was obtained a value of 87.00% for accuracy and 0.916 for the AUC value. The values ​​are high enough for the classification of student opinion against this pandemic so that this research is classified as Excellent Classification.

Abstract

The impact of the covid-19 pandemic is so great that the government must have policies to reduce its impact. One of the government's policies is the new normal which requires all people to wear masks, keep their distance and wash their hands. In its application, of course, there are positive and negative sentiments uploaded to Twitter. This study aims to model the analysis of public sentiment regarding the government's new normal policy during the covid-19 pandemic in Indonesia. The stages of this research are data crawling, labeling, neutral data removal, preprocessing, distribution of training data and data testing, creation of a nave Bayes classification system, system testing and visualization of research results using wordcloud. The classification system performance includes 80.37% accuracy, 87.38% precision, 82.57% recall and 84.91% f-measure. The results of this study are 5194 tweets classified as positive sentiment and 2908 tweets classified as negative sentiment, this shows that there are more positive sentiments than negative sentiments. But from the numbers it can be seen that the comparison is not too far between positive and negative sentiments, meaning that there is a lack of public response to the new normal government policies during the pandemic.

Abstract

Abstract—Microcontrollers are now growing rapidly and are increasingly in demand on system applications control. These days, there are many microcontrollers that already in module form. One of the microcontroller module that is widely used is Arduino. Arduino is a type of board which contains a microcontroller. Combined with the ESP8266-01 module and NodeMCU makes the microcontroller can be connected via internet network. Microcontroller board device Arduino makes it possible to process the temperature reading data from the temperature sensor for support to the display unit using an android based smartphone and controlling AC temperature using Telegram. The processing result data from this Arduino board will be transmitted using wireless media connected to internet network.

Abstract

Tulap Village is one of the villages in Minahasa that has a Village-Owned Enterprise (BUMDES). In marketing activities, the products sold are still only offered to families, local communities, and tourist attractions in Tulap Village. Marketing outside the village must be carried out in cities such as Manado and Bumdes is looking for a place to sell these products. The rental service for goods is still limited to the surrounding community because information about the business is not yet available. The system development carried out in this study uses the Waterfall model (Pressman, 2010). System modeling is documented using Data Flow Diagrams (DFD). The result of this research is a sales information system that can help customers see the products being sold or the goods rented by BUMDes Tulap. Testing this system using the blackbox and whitebox testing method.

Abstract

Wira Wacana Christian University Sumba in supporting its activities as an educational institution is required to use the Academic Information System. Having an academic information system like the web-based Ecampuz certainly requires auditing, monitoring and evaluation of its performance so that the services produced continue to show good quality. The aim of this research is to evaluate and audit system by using Cobit 5 frameworks, while testing and measuring website quality is using the Apache Jmeter tool. The Cobit5 processes used are: Risk Optimization (EDM03), Security Management (APO13), Risk Management (APO12), Change Management (BAI06), Operations Management (DSS01), Service Requests (DSS02), Troubleshooting (DSS03), Security Services (DSS05), Work Monitoring and Evaluation (MEA01), Internal Control of Monitoring and Evaluation (MEA02). Gap analysis and Maturity Level are aimed at obtaining Audit results with good maturity. The results obtained from the average value based on the gap analysis of 10 Cobit5 processes is 1.2 and the Apache Jmeter test shows throughput of 101.746/minute and Deviation is 3671.

Abstract

The development of technology is very rapid in today's era, especially with the development of internet technology. In the field of education itself, publication and access to research references can be easily done via the internet. However, with the internet also, research journal piracy can occur when access to references cannot be obtained due to paywall barriers (cannot access if you do not pay). Expressions of this can be found on social media, where users can use the platform to express their opinions freely. The availability of these data on the internet that can be retrieved and analyzed so as to produce information. In this study, we will analyze public sentiment towards one of the research article hijacking sites, namely Sci-Hub. The method used is Lexicon-based which is a method that uses a dictionary for classifying sentiment text. The data used are 35,755 tweets with 28,193 English-language tweets and 7,552 Indonesian-language tweets. The data is classified according to the rules in the InSet dictionary with the results of the classification of positive sentiment 59.51%, negative sentiment 26.42% and neutral sentiment 14.07%. This study obtained an accuracy of 55.66% for the prediction of data with positive, negative and neutral sentiments.
