Apart from that, the recording of the purchase and sale of spare parts still uses manual recording so that distorting data on the purchase and sale of spare parts is still deemed inefficient and ineffective. Making reports that are long and deemed ineffective makes researchers want to develop a system at PT Bintang Kharisma Motor. In making the system at PT Bintang Kharisma Motor made with UML diagrams consisting of three diagrams, namely usecase diagrams, activity diagrams, and class diagrams as the initial system design to be made, then programming is made with the PHP programming language according to the existing user interface design. and MySql as database. The system that has been created can help distort sales / service data, purchase and create purchase and sales reports faster than before, and the system helps in processing complaint data, ordering services, and measuring the level of service provided at PT Bintang Kharisma Motor.

This shows that there is a very large opportunity for data sources that can be used to find out positive and negative public sentiment regarding the Indonesian government's policy regarding Covid-19 vaccination. The method used to classify in this research is Support Vector Machine with various kernels. The kernels used are Linear, RBF, Polynomial, and Sigmoid. The classification results using the kernel are that the RBF kernel produces an accuracy of 88.8%, the Linear kernel produces an accuracy of 88.3%, the Sigmoid kernel produces an accuracy of 87% and the Polynomial kernel produces an accuracy of 85.5%. Based on the classification process that has been carried out, the highest accuracy is generated by the RBF kernel and the lowest accuracy is generated by the Polynomial kernel.
