Abstract

PT. Armada Internasional Motor (PT. AIM) is anautomotive company that has not only a sales division but also aworkshop division. There are some problems that occur in theworkshop division of PT. AIM, namely the ineffectiveness of datarecording of new customers for new services, as they are usingdesktop-based application, hence, the customers must come tothe office beforehand. Furthermore, the data of service needsand the Letter of Reparation Order by the Checker are notdirectly known since they are in the desktop-system located inthe office, and the Service Advisor (SA) cannot directly find outwhether the service has been completed or not because theChecker has to make a manual report to SA. From some of thoseproblems, it is concluded that a data recording system with theportable and efficient mobile technology is highly needed. Theresult of this study is an application of car service data recordingfor both the SA and the Checker. The system of car service datarecording applies Google Cloud Messaging (GCM) technology tofacilitate the delivery of notice to the SA and the Checker.

Abstract

Presence is an activity that is often carried out by students, employees and staff. The attendance methods used are quite varied, ranging from manual attendance, fingerprints, etc. This method still has shortcomings such as manual recording. This research aims to design a website-based Global Positioning System (GPS) presence system at the Center for Innovative Teaching and Learning (P3I). The design was carried out using a supporting tool, namely Entity Relationship (ERD). The research method used by the author is the waterfall method which develops systematically from one stage to another like a waterfall. The testing stage uses 2 methods, namely alpha beta testing and system testing, in alpha testing in the test results table, results are obtained if the system runs without problems and is in accordance with user needs and beta testing is testing carried out by interview while system testing is testing by distributing questionnaires to find out the level of acceptance of the attendance system. Based on the interviews conducted, it can be concluded that the online presence website is user friendly or easy to operate and is in accordance with the objectives and benefits of the research conducted. Based on research and testing carried out.

Abstract

The graduation rate of students is an important measure of a school’s success, as it indicates the school’s ability to help students complete their education. Predicting student completion is crucial for schools to identify at-risk students and offer them early interventions to improve their academic performance. This can also assist policymakers in developing effective policies and programs to enhance graduation rates and reduce dropout rates. The dataset used in this study was obtained from the Kaggle website, and the best model proposed utilizes the Random Forest method with hyperparameter tuning. By adjusting the n_estimator parameter to 1000, our proposed method decreases the mean squared error (MSE) value from 0.5525155 to 0.5374983 and increases the R2 Score value from 0.9984039 to 0.9984873. The study also compares the performance of the proposed model with other datasets sourced from the University of California Irvine (UCI), demonstrating superior performance across all experiments. The results consistently show a decreasing trend in MSE value and an increasing trend in R2 value for all datasets

Abstract

Indonesia has a wide variety of tourism destinations or tourism destinations that are useful as a place to have fun with family or friends, to calm down from various activities as well as an educational place for children to be more interested in learning. PT. Panorama Indah Permai (Saloka Theme Park) is one of the tourist destinations in Indonesia and is currently operating again when the Covid-19 pandemic enters Indonesia and results in changes in visitors coming to amusement park tourism. Therefore, a comparison of ARIMA, Prophet, and Long Short-Term Memory (LSTM) algorithms was made to determine the algorithm that is suitable to be used as a predictive model of amusement park ticket sales. The Data obtained comes from historical data and must go through several processes such as pre-processing and algorithm testing to ensure the accuracy of the data with the algorithm. The results obtained from three forecasting models, it was obtained that the ARIMA algorithm has a value of RMSE of 762,009 and MSE of 580,659,053.

Abstract

The internet connection should typically function without any issues at all times. However, there are instances where the link does not function properly because to impediments or other issues.. The GNS3 Network Simulator tool is used in this study to carry out the simulation. The goal of this strategy is to determine whether it can sustain the internet network's quality and traffic levels while distributing the load throughout the network channel. Correct server path management will also be accomplished using the IP Hash technique. Using the PCC load balancing method, the traffic load is obtained more smoothly without data accumulation. Because the other network functions as an internet provider, internet access will still be accessible even if one of these networks dies. While using IP hash, the test results obtained an average throughput with the small data request category of 16.69 KB/s. with the medium data request category of 54.31KB/s and 1200 KB/s for the large data request category.

Abstract

The development of technology in online transportation services like Gojek has a significant impact on meeting the mobility needs of modern society. The city of Salatiga, with many students from outside the island, has a considerable number of individuals without their own vehicles who prefer to use Gojek services. Therefore, research was conducted to analyze the preferences of students in Salatiga in determining the type of Gojek online transportation using the Naïve Bayes method. One hundred questionnaires from Salatiga students were collected, and the results yielded probability values for Gojek service preferences based on a combination of variables such as weather, load, destination, and time. It is evident from the probability values that weather and time variables play a crucial role in influencing users' decisions between using Go-Ride or switching to Go-Car. These results can provide guidance for Gojek in designing service innovations that are more responsive to user needs based on various specific factors.
