Abstract

This study aims to regulate bandwidth usage and monitor website access using MikroTik. Bandwidth regulation with the aim of equalizing internet use where the number of students and teachers is 500 people, while monitoring websites and blocking negative websites aims to limit student access, which amounts to 416 students, consisting of 120 junior high school students, 150 vocational high school students, and 150 students. SD 100 and students 66 people. This research was conducted at Asshodiqiyah Vocational School as a technology base in the school environment under the Asshodiqiyah Foundation. The Assodiqiyah Foundation oversees elementary, junior high, and vocational schools and accommodates foreign students as boarding students. The service location is located at Jl. Sawah Besar Timur No 99 Rt.9 Rw. 2 Kaligawe Village, Gayamsari District, Semarang City. The method used in this research is Research and Development (RD) [4]. This research discusses how to create and implement to the public how to use the Mikrotik tool as a regulator of bandwidth usage and see the sites that are accessed and if necessary block sites that are considered less suitable for students to access. The expected result is an even use of internet bandwidth and security of site access from negative things. So that students will avoid the negative influences that exist from the internet.

Abstract

Student satisfaction on the use of e-learning is an important role for the continuity of an educational institution, especially in the current era of the covid 19 pandemic, the process of teaching and learning activities that are usually carried out in offline classes is abolished and replaced by utilizing the e-learning system. Because of the importance of the role of e-learning as a medium for student learning, knowledge is needed to determine the level of student satisfaction of e-learning as an evaluation material for managers to improve the quality of e-learning so that it can provide optimal services to students. Therefore, a classification technique with data mining is needed using the c.45 algorithm method on the WEKA (Waikato Environment for Knowledge Analysis) software. The results show that 73% of students are satisfied with the e-learning of the State Islamic University of Semarang and 23% of students are not satisfied with an accuracy of 84.76%.

Abstract

Indihome users are growing rapidly. However, PT Telkom's indihome services are still experiencing various disturbances so that the quality of service is not optimal, with the large number of Indihome users, it is undeniable that there are technicians who understand one type of disturbance better than others and sometimes there are new disturbances that are not understood by many technicians. , technicians who do not understand even those who are familiar with certain disorders may make mistakes in making decisions in dealing with disturbances. This is what prompted the construction of an expert system that aims as a solution to help make it easier for technicians when an interruption occurs in the indihome service, the expert system allows technicians to make consistent decisions to avoid mistakes based on the knowledge of an expert, so that with the solutions provided, technicians are able to take action. what to do when a disturbance occurs and how to deal with the disturbance. The expert system used is the Best First Search algorithm method.

Abstract

Bagi entitas terbatas dokumen dapat bersifat rahasia dan penting, sehingga diperlukan mekanisme keamanan khhusus. Encryption with Covertext and Reordering (ECR) adalah salahsatu model keamanan dokumen berbasis teks. ECR menggunakan kunci acak untuk menghasilkan ciphertext. Kunci acak ECR dibuat secara manual. Penelitian ini bertujuan meningkatkan tingkat keamanan dokumen dengan menggunakan model enkripsi ECR. Kunci acak tabel permutasi diusulkan dalam perubahan model enkripsi ECR. Nilai acak akan dipilih secara otomatis menggunakan fungsi acak dari tabel permutasi. Dalam penelitian ini sebagai ukuran adalah entropi, yang merupakan nilai tingkat keamanan dokumen terenkripsi. Hasil eksperimen menunjukkan bahwa penyematan tabel permutasi dari kunci acak memberikan nilai entropi yang lebih baik, yang menyiratkan tingkat keamanan yang lebih baik. Penggunaan tabel permutasi kunci acak juga mempermudah penggunaan ECR untuk mengamankan dokumen

Abstract

Batik is an intangible cultural heritage that has been approved by UNESCO as an Indonesian cultural heritage. Batik is the art of drawing on cloth for clothing. This art of drawing is in the form of a pattern and has a philosophical meaning which is historically very closely related to the philosophy of Javanese culture. The various patterns of this batik need to be preserved, and one of the efforts to preserve this diversity is to maintain the special characteristics of the batik motif and continue to introduce it to future generations. Efforts to facilitate the introduction of batik motifs can be done through technology that is able to automatically recognize batik patterns according to the motif being tested, one of which is pattern recognition technology. This study aims to optimize the KNN method with PSO to increase the accuracy of batik pattern recognition, the research was carried out in several stages starting from data collection, preprocessing, feature extraction, and classification. The research was conducted using 310 data in the form of batik images in 7 different motifs and divided into 240 compositions for training data and 70 for testing data. At the feature extraction stage, the discrete wavelet transform method is used up to level 3, then at the classification stage, the PSO and KNN algorithms are used. The PSO algorithm is used to obtain the most optimal number of k which is used as the input parameter k in the KNN algorithm. The results of the research that have been carried out have proven that with the addition of the PSO algorithm, the accuracy of the KNN method can be increased by 6% compared to the standard KNN method.

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..
