Sistem Informasi Akademik (SIAKAD) merupakan sistem yang digunakan untuk membantu aktivitas belajar mengajar pada suatu universitas. Sejak pertama kali dikembangkan, SIAKAD Universitas Islam Negeri Sunan Ampel Surabaya (UINSA) belum banyak dilakukan penelitian mengenai kepuasan penggunanya sehingga diperlukan penelitian untuk mengetahui efektivitas SIAKAD UINSA berdasarkan kepuasan penggunanya. Penelitian ini bertujuan untuk mengetahui kepuasan pengguna SIAKAD UINSA. Penelitian ini berjenis kuantitatif dengan metode End User Computing Satisfaction (EUCS). Sampel diperoleh dengan teknik random sampling sehingga didapatkan 392 responden yang terdiri dari mahasiswa, dosen, dan pegawai akademik bagian operator SIAKAD. Data yang diperoleh dianalisis dengan teknik analisis faktor. Hasil penelitian menunjukkan bahwa kepuasan pengguna berdasarkan indikator content sebesar 2,853; accuracy sebesar 0,708, format sebesar 0,616; ease of use sebesar 0,432; dan timeliness sebesar 0, 391.  Berdasarkan hasil tersebut dapat diketahui bahwa indikator content memiliki pengaruh terhadap kepuasan pengguna SIAKAD di UINSA sedangkan keempat indikator lainnya belum mempengaruhi kepuasan pengguna

The research aimed to create a fresh chicken meat identification system to detect differences between formalin and non-formalin chicken meat based on the image of raw chicken meat. Feature extraction method used is the Feature Texture method which is included in the statistical method where the statistical calculation uses a gray degree distribution (histogram) by measuring the level of contrast, granularity, and roughness of an area from the neighboring relationships between pixels in the image then feature extraction, results feature extraction is then classified by K-NN. With the classification using K-NN results obtained high classification accuracy. The K-NN method is a very good method of dealing with the problem of recognizing complex patterns in the form of data training and processing calibration, based on very fast and high accurate literature methods more than other methods. Observation images will be carried out at various distances between the smartphone camera and chicken meat samples.

Situbondo Regency is one of the regencies in East Java Indonesia that is thick with Madurese culture and its religious community. In this area, it is also the center of Islamic boarding schools. Interestingly, although in this regency is a pesantren base, there is one pesantren which is quite old and a pioneer in the development of the creative economy through a handicraft called batik (batik tulis).

Extracurricular activities at MAN 1 Lamongan are still determined without any support from the system. Students are only given extracurricular information and can register according to the conditions if interested. This makes the extracurricular that students have chosen does not fully match their abilities. The result is a decrease in the number of members who are active in extracurricular activities due to loss of interest. A web-based system was developed to assist MAN 1 Lamongan in determining extracurricular according to interests and talents. Case-Based Reasoning (CBR) is the system framework and Certainty Factor (CF) is the algorithm for determining the certainty value. The result is that with test data of 68 students, the system recommends extracurricular well. Testing with Confusion Matrix obtained precision level of 96.03% (high), recall of 99.4% (high), accuracy of 95.76% (high)
