Computer system architecture is one of the subjects that must be taken in the informatics engineering study program. In the study program the graduation of each student in the course is one of the important aspects that must be evaluated every semester. Graduation for each student / I in the course is an illustration that the learning process delivered is going well and also the material presented by the lecturer in charge of the course can be digested by students. Graduation of each student in the course can be predicted based on the habit pattern of the students. Data mining is an alternative process that can be done to find out habit patterns based on the data that has been collected. Data mining itself is an extraction process on a collection of data that produces valuable information for companies, agencies or organizations that can be used in the decision-making process. Prediction of graduation with data mining can be solved by classifying the data set. The C5.0 algorithm is an improvement algorithm from the C4.5 algorithm where the process is almost the same, only the C5.0 algorithm has advantages over the previous algorithm. The results of the C5.0 algorithm are in the form of a decision tree or a rule that is formed based on the entropy or gain value. The prediction process is carried out based on the classification of the C5.0 algorithm by using the attributes of Attendance Value, Assignment Value, UTS Value and UAS Value. The final result of the C5.0 algorithm classification process is a decision tree with rules in it. The performance of the C5.0 algorithm gets a high accuracy rate of 93.33%

Problem-based learning Metode Pembelajaran that is integrated with information and communication technology is expected to be able to provide solutions to increase attractiveness and problem-solving abilities. The purpose of study optimizes PBL Metode Pembelajaran by applying information and communication technology so that there is an increase in the problem-solving ability of the resulting Metode Pembelajaran. Experiments were carried out to get the best Metode Pembelajaran test with indicators of increasing achievement and problem-solving abilities. This research is a Classroom Action Research there are 4 steps: Planning, Action, Observation, and Reflection. The results study The application of contextual learning in applied mathematics courses 2 are: (1) the results of the distribution of questionnaires of students' interest in learning integrated problem based learning ICT before and after being given a learning treatment Problem-based learning has changed from cycle I which is 22.87% increased to 89 00% in cycle II, (2) Increasing student learning activities, this can seen from the percentage  activity in the first cycle of 64% classified as quite active, and in the second cycle by 76% and classified as active, (3) improving achievement, activity, and interest in student learning. This increase can be seen by the acquisition of the average of students in the first cycle of 66.88 and with student learning completeness of 56%. The average value in cycle II is 78.27 and the student learning completeness is 100%.

Dalam penelitian ini populasi adalah Mahasiswa Prodi DIII Teknik Mesin, kemudian untuk sampel yang digunakan adalah kelas 2B yang merupakan mahasiswa semester 2 Tahun Akademik 2019/2020. Penelitian ini memiliki tujuan meningkatkan kemampuan pemecahan masalah yang dengan memadukan teknologi komputasi mengunakan software Wolfram Mathematica. Penelitian merupakan Penelitian Tindakan Kelas dengan 4 tahap yaitu Planning, Acting, Observing, Reflecting. Hasil riset yang telah dilaksanakan dengan aplikasi inovasi pembelajaran komputasi Wolfram Mathematica adalah sebagai berikut : (1) Hasil Rekap kuisioner yang telah dibagikan dan dan di isi langsung oleh mahasiswa memiliki prosentase 24% meningkat menjadi 88% pada siklus ke , (2) Terdapat peningkatan aktifitas belajar mahasiswa dengan diskripsi pada siklus 1 memiliki Prosentase 63% yang memiliki tingkat keaktifan pada tingkat cukup aktif, dan pada siklus II sebesar 75% yang memiliki tingkat keaktifan pada tingkat aktif, (3) Terdapat pula pengingkatan pada kemampuan pemecahan mahasiswa, tingkat keaktifan, dan minat belajar pada mahasiswa yang terlihat dengan indikator perolehan nilai rerata mahasiswa pada siklus 1 sebesar 65 serta tingkat ketuntasan belajar mahasiswa dengan capaian 55%. Kemudian nilai rerata mahasiswa di siklus 2 di peroleh dengan tingkat 77 serta tingkat ketuntasan mahasiswa dalam proses pembelajaran mencapai 98%, sehingga dapat di simpulkan terdapat perubahan positif yang sangat siginifikan dan efektif.

Seiring perkembangan zaman, tingkat kebutuhan akan teknologi semakin meningkat bagi masyarakat. Bukan hanya kecanggihan saja yang diperlukan tetapi efisiensi dan keefektifan teknologi tersebut diharapkan dapat membantu masyarakat. Salah satu teknologi yang efektif dan efisien terhadap penggunaan waktu adalah teknologi live streaming. Pada makalah ini diusulkan sebuah sistem penyiaran radio streaming yang dapat diakses oleh setiap user yang terhubung pada jaringan melalui sebuah media player (Winamp) dalam sebuah jaringan local salah satunya adalah radio kampus. Adanya radio streaming di kampus, mahasiswa tidak lagi ketinggalan informasi yang terupdate di dalam kampus serta untuk mencapai efisiensi dan efektivitas kerja dengan hasil yang maksimal.
