The world of education has a good level of reputation if it has a professional educator staff and with high integrity, one of the examples is that educators must be hardened on time and not truant to teach students at school. So that the stigma of students and the community does not give a negative value. The role of the principal is also very important to build high integrity, a principal must always monitor every day the teachers who enter the class. But the limitations and the many teaching hours of teachers that must be monitored make the principal difficult because of limited time and other busyness. So the need to design and build an Android platform-based application that is intended to monitor the schedule, and the presence of teachers in real-time called Teacher Attendance Monitoring System Teaching with QR-Code and Geo-Location. SoftwareThe software is intended to make it easier for principals to monitor teachers who teach in class in realtime. Black box testing results show 100% for functional testing of systems and for testing the application interface has a 100% success rate. Then the software is feasible to use.

A quality website has five parameters that must be considered are: information, security, convenience, comfort, quality of service. But of course, the fifth parameter does not always guarantee the amount through its Web page will increase, from that problem. So research is conducted to predict website content based on visitor data with a data mining approach, this research aims to improve the quality of content on target according to the interest of website visitors. Evaluation of random forest algorithm has the value the accuracy of classification of 71 percent by value of Kappa 0.712 whereas the k-NN algorithm has higher accuracy values of random Forest algorithm i.e. worth 84.88 percent and kappa values of the mean 0.847 the k-NN algorithm performs data processing process predictions against data of web content more effectively than the random forest

Abstrak. Dana Sumbangan Pembinaan Pendidikan (SPP) biasanya dipergunakan untuk pendanaan berbagai macam kegiatan di sekolah, mulai dari penggajian guru honorer yang terdapat pada sekolah swasta maupun negeri, pengadaan alat praktik, mencetak soal-soal ujian, serta operasional lainnya. Masalah yang terkait dengan SPP di lingkungan berdasarkan data yang diperoleh banyaknya siswa-siswa yang sering sekali menunggak pembayaran SPP sampai beberapa bulan, bahkan sampai siswa-siswa tersebut lulus. Atas masalah tersebut dilakukan penelitian untuk menganalisa potensi menunggaknya SPP siswa berdasarkan besaran pendapatan orangtua dengan pendekatan Business Intelligence menggunakan metode decision tree. Hasil analisis yang didapatkan siswa yang memiliki orang tua dengan pendapatan atau penghasilan kurang dari Rp 672.500,00 akan berpotensi menunggak pembayaran SPP lebih dari Rp 900.000,00 pada setiap bulannya, sedangkan orang tua siswa yang memiliki penghasilan diatas Rp 672.500,00 berpotensi memiliki tunggakan kurang dari Rp 900.000,00 atau tidak menunggak pembayaran SPP. Untuk evaluasi efektifitas algoritma decision tree terhadap pengolahan data, memiliki nilai akurasi ebesar 95.97%, dengan presisi 94.96% nilai tersebut mengartikan algoritma memiliki korelasi yang baik berdasarkan atribut dan data yang telah di proses oleh algoritma.Abstract. School tuition fee is typically used for funding school operational, i.e. paying honorary teachers in public and private schools, purchasing practical instruments, printing examination worksheets, and other net-operational costs. According to the discovered data in the research environment, the funding is unable to be acquired properly due to students" school tuition fees arrears for months even years until they graduate. Considering the condition, this research is conducted to identify the potential of students" school tuition arrears, based on the sum of their parents" salaries centered on the business intelligence approach, using the decision tree method. The analysis results show that, students whose parents" income is less than Rp 672.500,00 will be potentially in arrears with school tuition more than Rp 900.000,00 each month, while students whose parents" income is above Rp 672.500,00 are potentially in arrears of less than Rp 900.000,00 or not in arrears. To evaluate the effectiveness of the decision tree algorithm for data processing, it has an accuracy value of 95.97%, with a precision of 94.96% that means the algorithm has a good correlation based on attributes and the data that have been processed by the algorithm.

Online media is used by many organizations as a helping tool to reach the goal in the business process especially marketing or introducing a product that is marketed. Therefore, this research is trying to explain how massive the role of online media is, in the business process in the town of Tasikmalaya based on a statistic number scale from the data that refer to quantitative methodology, Discrete Data, and Correlational analyses method. Meanwhile. The result of this research reveals Online media is, towards business process marketing and service in the town of the Tasikmalaya area positively affected business process marketing and service. These results are supported by the results of data processing. From 78 organizations, the positive rate of online media on marketing and services is 95% greater than the positive level, which is only 5%. sig. (2-sided) of 0,000, meaning that α=0.05 is greater than the value of Sig. (2-sided) or [0.05> 0,000]. This shows that the variable X has an influence on variable Y. The results of the analysis of bivariate people, obtained the final value r =1, for the estimated value. This number defines the variable X which has a very strong attachment relationship to a variable.

Public interest in the modern market has increased rapidly, resulting in market business actors having difficulty in handling a large number of transactions as experienced by one of the market business players, namely Qini Mart Tasikmalaya. This study aims to create a Point of Sales (POS) application program in market businesses that can handle good retail management processes. In this study, we used a spiral model to build or design a POS application at Qini Mart Tasikmalaya. In this model, there is a risk analysis that is useful arising from the needs and designs that have been made in previous stages so that they can adjust, simplify, and speed up the retail management process. Black-box testing is used to determine the level of functionality and interface of the system that we have developed. The findings resulted in a POS application used at Qini Mart Tasikmalaya in accordance with the design we have made. In addition, the results of black-box testing show that all functional and interfaces on the system are running well, where this system can speed up the process of calculating sales transactions, printing payment notes, facilitating the process of managing goods data, and making more accurate sales reports.
