Every year the area of paddy fields in Karawang Regency has increased and decreased due to land conversion. Climate change also causes changes in the amount of rain and rain patterns that cause shifts in the beginning of the season and the planting period. If the decrease in planting area will be affected, then the price of rice will increase and farmers will maintain the area and not convert their rice fields to function, therefore a study was conducted to predict the rice planting area in order to know the description of the area of rice planted in Karawang Regency will increase. , decreased or stabilized. So the search for information on the data on the area of rice planting in Karawang Regency was carried out. A total of 180 data were processed using data mining techniques so that they could mine information from the data. Data mining is a technique of extracting or new discoveries from large data and then extracting the data into information that can later be used. Experiments were carried out using the CART algorithm and cross validation using the Weka tools. The results of the evaluation carried out can be concluded that the CART algorithm using different K values provides different evaluation results. The performance of the algorithm is seen from the accuracy, precision, recall and F-Measurement, thus providing different performance values for each result. The value of k=8 has the highest accuracy value, which is 90% with precision 0.918%, recall 0.906% and F-measure 0.949%.

Teacher performance evaluation is one of the efforts to raise the standard of education at SDI Darul Mu'minin. SDI Darul Mu'minin, which is located in Larangan Indah Village, Larangan sub-district, Tangerang City, has a teacher performance assessment that is conducted once a year. In addition to raise the standard of education, the purpose of the assessment is to select exemplary teachers. However, the process of assessing teacher performance is not on target because the assessment process only uses attendance criteria and does not yet have the right method. Therefore the principal added several additional criteria, namely: responsibility, lesson plans, loyalty and reporting of student grades. To implement a multi-criteria assessment, a decision support system is needed. This study uses the AHP and SAW methods and produces weights namely Responsibility 33%, Loyalty 28%, Attendance 18%, Lesson Plans 13% and Reporting of Student Values 8% and produces the best alternative, namely the best performing teacher with a value of 0.9930. The goal of this research is to decide the best alternative, namely the best performing teacher who will receive a prize or reward in the form of money at the end of each academic year.

Decision Support System Using Simple Additive Weighting (SAW) Method For Teacher Performance Assessment At SMP Ki Hajar Dewantoro

2023-03-15T11:04:05+07:00

The teacher is a qualified educator who is responsible for teaching, and has a function and role in educating the nation's daily life. So that the roles and responsibilities in the teacher's functional position to be done according to the applicable regulations, a teacher's work assessment is needed which can guarantee a quality learning process at SMP Ki Hajar Dewantoro. In the process of selecting the best teacher for SMP Ki Hajar Dewantoro, there was already a weighting of the assessment criteria. However, a number of challenges arise, including the procedure of assessing teacher performance still using conventional methods with paper and ordinary calculations, so that the results of the assessment can occur errors or are inaccurate, and take a little time. Teacher ratings are also inaccurate and subjective, making it difficult to determine the best teacher. In addition, the decree for the best teacher is not well preserved. Therefore, a Decision Support System (DSS) is needed to recommend the best teacher using thethe Technique known as SAW (Simple Additive Weighting). The SAW approach was chosen due to it uses a method of ranking to choose the best option from a number of others and then determines the preference weight value for each option, specifically, the teacher with the highest rank according to the specified standards. due to the fact that it is based on the weight value of the existing criteria, this method will make the assessment faster, it can provide the best alternative teacher ranking. With the results of these rankings, it can simplify and assist the school in accelerating the assessment of teacher performance, so that more accurate results will be obtained as a decision tool.
