Abstract

Student Assessment System is a student score processing system based on the K13 curriculum. The 2013 curriculum has four aspects of assessment, namely aspects of knowledge, aspects of skills, aspects of attitudes, and behavior. In the 2013 curriculum, especially in learning materials, there are materials that are streamlined and materials that are added. The streamlined material appears to be in Indonesian, Social Studies, PPKn, and so on while the added material is Mathematics. In this study, the authors found several problems that occurred at SMA Xaverius 1 Palembang, including the difficulty of distributing grades starting from the teacher then the homeroom teacher and finally the vice principal in the academic field according to the K13 curriculum. The second is how the student assessment system is carried out in an integrated manner by a system, so that the value data is centered on one data source. The third problem is how to give a deadline when entering grades, so that teachers and homeroom teachers are administratively orderly in entering student grades. The student grade management application is built with the Codeigniter 3 framework, which makes grade data centralized, and grade distribution fast. With the facility of limiting the time for input values, the teacher is in an orderly administration. Parents can monitor their child's study progress with access to the application to view student report cards..

Abstract

With the rapid growth of social media in recent years, opinion mining, also called Sentiment Analysis, has gained much attention. Opinion mining refers to the use of Natural Language Processing (NLP), text analysis and biometrics to analyse, extract and identify the customer views of a product. The polarity classification is a main task of opinion mining for getting useful decision from online customer reviews and survey responses. Existing approaches in opinion mining performs the classification based on the parametric form. In this paper, we introduce the Naive Bayes classifier with Kernel Density Estimation (KDE) as a non parametric way of opinion mining that computes the probability density function based on the kernel estimator.  The features are extracted from the opinions in the document level and are used to train the classifier in a supervised manner.  KDE also performs data smoothing problem that inferences about the population that are based on finite data sample. We underwent some pre-processing techniques like stemming and stopword removal. Experimental results show that the proposed algorithm performed well, in terms of accuracy, precision, recall and F-measure.

Abstract

Pada era digital sekarang hampir semua orang mengakses internet, Website merupakan salah satu situs yang ada di internet yang dapat menyimpan dan menyebarkan segala informasi. Seiring dengan perkembangan teknologi, keamanan suatu website mulai terancam karena maraknya serangan-serangan yang dilakukan oleh penjahat digital. Website yang memiliki sistem keamanan yang lemah akan rentan oleh serangan ancaman yang dapat terjadi sewaktu-waktu. Kasus kerentanan yang sering ditemui yakni Cross Site Scripting (XSS) dan Rate Limiting. Untuk mengantisipasi hal tersebut, aplikasi OWASP ZAP dapat dimanfaatkan untuk menguji kerentanan XSS yang ada pada sebuah website, salah satunya pada website sekolah SMA Negeri 8 Denpasar. Pengujian kerentanan XSS dilakukan dengan cara melakukan pemindaian, kemudian generate report. Melalui report tersebut, dilakukan analisis untuk membuktikan ada atau tidaknya kerentanan XSS pada website yang bersangkutan. Sedangkan, kerentanan Rate Limiting diuji secara manual pada fitur login website SMA Negeri 8 Denpasar, dengan cara memasukkan username dan password secara acak dan berulang-ulang. Kata Kunci—OWASP ZAP, Rate Limiting, XSS, Kerentanan

Abstract

Laundry Cucimania merupakan sebuah bisnis yang bergerak dibidang jasa pencucian pakaian. Semua pencatatan masih dilakukan secara konvensional mulai dari pembuatan nota, pencatatan transaksi, dan pencatatan data pelanggan. Setiap pencatatan transaksi disimpan dalam sebuah buku, sehingga terjadi penumpukan arsip fisik yang dapat menimbulkan banyak masalah dalam pembuatan laporan transaksi, pencarian data dan perhitungan data. Tujuan penelitian ini adalah merancang sistem yang dapat mengelola data dan transaksi  menjadi terkomputerisasi dan otomatis sehingga operasional berjalan lebih efisien dan data menjadi tersimpan lebih baik. Menggunakan metode waterfall yang terdiri dari lima fase: analisis kebutuhan perangkat lunak, desain, pembuatan kode program, pengujian, dukungan, atau pemeliharaan. Sedangkan untuk pengumpulan data dilakukan dengan observasi, wawancara, dan penelusuran literatur yang berhubungan dengan penelitian ini. Hasil penelitian menunjukkan bahwa sistem yang sudah terkomputerisasi membuat operasional menjadi lebih efektif dan efisien, data transaksi tersimpan dengan rapi sehingga membuat rekapitulasi data lebih efisien, serta meminimalkan kesalahan input maupun kesalahan hitung.

Abstract

Jahe merupakan tanaman rimpang yang memiliki banyak manfaat, seperti bumbu masak, jamu, obat herbal, dan lain-lain. Rimpang jahe memiliki fungsi yang berbeda-beda, tergantung jenisnya (Jahe Sunti, Jahe Kombongan, dan Jahe Merah). Identifikasi jenis jahe dapat dilakukan oleh manusia dengan mudah mengingat jenis jahe yang sedikit. Namun, identifikasi oleh manusia cenderung tidak konsisten dan belum tentu memberikan hasil yang akurat. Oleh karena itu, tujuan dari penelitian ini adalah untuk membuat suatu sistem yang dapat mengklasifikasikan jenis jahe secara akurat. Metode penelitian yang digunakan adalah K-Nearest Neighbor (K-NN) dan ekstraksi ciri statistik orde pertama (mean, variance, skewness, kurtosis, dan entropy). Sedangkan pengujian sistem menggunakan metode Black-Box untuk menguji fungsionalitas dan metode Confusion Matrix untuk menguji akurasi. Hasil pengujian menunjukkan bahwa sistem klasifikasi jenis jahe berdasarkan karakteristik statistik orde satu warna rimpang menggunakan metode K-Nearest Neighbor (K-NN) memiliki performansi yang baik dengan akurasi 80%.

Abstract

Mandala Bhakti Health Vocational School Surakarta is a vocational school that focuses on the health sector and has two majors, namely nursing and pharmacy. The use of computers at the Mandala Bhakti Health Vocational School in Surakarta has begun to be applied to help work in the field of school administration, especially the student payment administration section which serves all student payments including medical tests, tuition fees, practicum, competency tests, re-registration, and registration.However, the administrative process for student payments still takes quite a long time because students must first write a payment slip and wait for a payment receipt from the treasurer which is written manually and the recording process must be done twice, namely per day and class. In addition, the passbooks and receipts that are used by students to see the payments that have been made, are mostly lost and damaged, making students not know what bills to pay. Therefore, it is necessary to have a Student Payment Administration Information System that can speed up the payment process, simplify the reporting process, and grant access rights for students to view payment history and bill payments.This Student Payment Administration Information System was created based on a website using visual studio code software (text editor), MySQL database management system (DBMS), Xampp, and the PHP programming language. Methods of data collection are done using interviews, observation, and literature study. While in its construction, the author uses the RAD (Rapid Application Development) development method which consists of requirements analysis, modeling analysis, modeling design, and construction.Testing the student payment administration information system uses black box testing which shows that the system is functioning properly without any errors. User testing was carried out using a questionnaire which showed the results that for the admin, treasurer, and principal access rights questionnaire the highest score was the 'agree' option with a percentage of 60%, while for the student access rights questionnaire, the highest score was the 'agree' option. with a percentage of 55%. This shows that the student payment administration information system is following the needs of its users
