Many parties take advantage of this technological advancement, one of which is in the learning process or online which is generally known as e-learning as a public service that has been implemented at STKIP NU Tegal which can be accessed through the campus academic website. However, technological advances cannot be avoided from threats or losses so they must be balanced with preventable harm or loss. This study aims to realize the performance of the information system and governance of e-learning learning that has been running. This study uses the COBIT 4.1 framework with the domain of Monitoring and Evaluation and Delivery and Support using the technique of calling the questionnaire data with selected sources according to the domain and Control Objective used. From the research results, it was found that STKIP NU has Elearning management in supporting both online learning services and it is felt that there is a need for improvements to some very important control processes that are related at this time</em><em>.</em></p> Nurkholis . ##submission.copyrightStatement## 2020-12-30 2020-12-30 1 2 78 83 PREDIKSI KELULUSAN MAHASISWA MENGGUNAKAN ALGORITMA C4.5 (STUDI KASUS DI UNIVERSITAS PERADABAN) https://journal.peradaban.ac.id/index.php/jtikom/article/view/635 <p><em>Students are </em><em>an important parameter in implementing a study program, many students have different graduation rates, are on time and are not on time. This is an obstacle for the University in general because the number of graduations each year is one of the factors that will be assessed for applying for accreditation. This study aims to determine the level of accuracy of the C4.5 algorithm in predicting student graduation, using the C4.5 decision tree algorithm method. Student data used as attributes are IPK, credits, age, gender. The results of the analysis in this study indicate that the C4.5 algorithm can predict with an accuracy value of 88.07% with a precision of 91.79% and a recall of 95.34%</em>.</p> Ade Fatma Ayu Rahman Sorikhi . sri wartulas ##submission.copyrightStatement## 2020-12-30 2020-12-30 1 2 70 77 ANALISIS RECOVERY BUKTI DIGITAL INSTAN MESSENGER PADA SMARTPHONE ANDROID MENGGUNAKAN METODE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST) STUDI KASUS : KASUS PERSELINGKUHAN https://journal.peradaban.ac.id/index.php/jtikom/article/view/627 <p>Teknologi pada perangkat mobile sangat pesat perkembangannya jika dibandingkan dengan teknologi pada perangkat computer <em>desktop.</em> Saat ini hampir setiap orang sudah memiliki perangkat mobile seperti HP dan <em>Smartphone </em>khususnya android. Banyak pihak yang memanfaatkan perkembangan teknologi ini baik untuk tindak kejahatan maupun untuk kegiatan positif. Termasuk di dalamnya untuk tindakan perselingkuhan. Beberapa orang memanfaatkan teknologi tersebut agar tidak diketahui oleh pasangannya. Salah satu metode yang sering digunakan yaitu <em>National Institute Of Standards and Technology (NIST). </em>Metode ini menjadi dasar dari pengolahan <em>digital forensics </em>dari awal sampai dengan akhir. Sedangkan <em>tools </em>yang banyak digunakan untuk mengakuisisi bukti digital pada perangkat <em>smartphone </em>yaitu <em>Oxygen Forensics.</em></p> Achmad Syauqi ##submission.copyrightStatement## 2020-12-17 2020-12-17 1 2 65 69 PENERAPAN ALGORITMA K-MODES DAN C4.5 UNTUK PREDIKSI PEMILIHAN JURUSAN DI UNIVERSITAS PERADABAN PADA SISWA SMA (Studi Kasus: SMA Islam Ta’allumul Huda Bumiayu) https://journal.peradaban.ac.id/index.php/jtikom/article/view/626 <p>Banyak siswa kelas XII saat ini yang memiliki kecenderungan bahwa mereka belum mengetahui secara pasti minat dan bakatnya serta kelak akan memilih jurusan kuliah dibidang apa selepas masa SMA-nya nanti. Beberapa kasus dalam kurang tepatnya memilih jurusan kuliah yang kurang sesuai dengan kemampuan atau keahlian, maupun minat dan bakat mahasiswa dapat mempengaruhi proses pembelajaran nantinya dibangku perkuliahan. Hal tersebut akan mempengaruhi perkembangan mahasiswa tersebut di dalam suatu jurusan kuliah yang dipilihnya. Untuk mengatasi permasalahan tersebut maka diperlukan suatu metode yang dapat memberikan prediksi jurusan pada siswa. Penulis bermaksud untuk mengimplementasikan metode dari Data Mining yaitu Algoritma K-modes dan Algoritma C4.5 sebagai metode untuk menggali potensi siswa dalam memilih jurusan berdasarkan nilai akademik dari siswa tersebut. Berdasarkan pengujian menggunakan confusion matrix terhadap 158 record data nilai siswa-siswi kelas XII SMA Islam Taallumul Huda Bumiayu angkatan 2018/2019 diperoleh akurasi sebesar 87,50% dengan predikat good classification</p> Afif Fauzi Nurul Mega Saraswati Rito Cipta Sigitta Hariyono ##submission.copyrightStatement## 2020-12-30 2020-12-30 1 2 57 64 APLIKASI PEMESANAN LAPANGAN FUTSAL ONLINE BERBASIS ANDROID (STUDI KASUS : PUTRA FUTSAL BUMIAYU) https://journal.peradaban.ac.id/index.php/jtikom/article/view/624 <p>Futsal is a sport that is very popular in Indonesia. In addition to a good field, a good field rental system is also a factor in consideration for tenants choosing futsal field rentals. Ordering and collecting data on Bumiayu Putra Futsal which is still manual will make the length of the process of recording and searching for information, as well as ordering systems that have to be face-to-face and come directly to a certain place will take a lot of time to do so. This can of course waste consumers' time, costs and power. Based on these problems the authors intend to build an information system that makes it easier for consumers and managers to get information about field schedules and futsal field orders. In building a futsal field ordering system the writer uses the waterfall method. Data collection techniques using observation, interviews, and library research program implementation used is the Android programming language. Based on the results of the analysis and discussion, the online futsal field ordering system can be accessed anytime and anywhere. In this system includes information on field schedules, and futsal field bookings, this system was built intended to provide facilities for futsal field owners to publicize their futures sites.</p> Giris prasetyo budi Fathulloh .
