Kantor Camat Siabu Kabupaten Mandailing Natal memiliki permasalahan dalam penilaian Kinerja pegawai berprestasi yang dilakukan sekarang masih dilakukan secara manual pada lembar penilaian berdasarkan nilai disiplin dan sasaran kerja yang dicapai pegawai itu sendiri. Sehingga pegawai yang berpotensi memiliki kinerja yang berprestasi tidak terlihat secara jelas. Penelitian ini bertujuan untuk merancang sistem pendukung keputusan dalam melakukan pemilihan pegawai berprestasi berdasarkan evaluasi kinerja pegawai dengan metode SAW (Simple Additive Weighting). Berdasarkan penilaian dua puluh enam orang pegawai ASN dan empat orang pejabat penilai atau responden, tahapan implementasi perhitungan SAW dalam sistem pendukung keputusan pemilihan pegawai berprestasi antara lain menentukan kriteria, menentukan kriteria penilaian, menentukan normalisasi bobot kriteria, rating kecocokan dari setiap alternatif pada setiap kriteria, normalisasi matriks, nilai akhir dari alternatif, dan hasil perankingan. Hasil dari penelitian ini adalah aplikasi sistem pendukung keputusan pemilihan pegawai berprestasi berdasarkan evaluasi kinerja dengan metode SAW dan telah memudahkan kecamatan siabu dalam pemilihan pegawai berprestasi

Along with the development of science and the globalization of information that demands the creation of an all-computerized state. At SMA Negeri 4 Tualang, Siak Regency, the process of processing library data to making reports still uses manual bookkeeping. This can cause the process of searching for book data, member data and book borrowing data to take a long time and not to mention if the data is lost so it cannot be used again. Library applications are made according to user needs using the PHP programming language with MySQL database storage and Waterfall modeling. This library application has been tested with the black box method with 100% results then implemented and measured with values and measuring indicators as follows: User Satisfaction = 94%, Data Accuracy = 93%, Speed and convenience = 96%, Application and information security = 93 % and Support = 96%. Thus the digitization of library management is very beneficial for library managers and students as users at SMAN 4 Tualang

The Faculty of Computer Science, Lancang Kuning University, as a private university in the city of Pekanbaru, uses the Sevima Edlink platform as a media for academic information systems and online learning. According to some students, there are still some obstacles encountered in understanding, using and functioning this edlink application. The purpose of this study was to measure the level of satisfaction of students of the Faculty of Computer Science in using Edlink using the C4.5 and Naïve Bayes algorithms. To measure the level of accuracy of the C4.5 and Naïve Bayes algorithms in order to measure the level of student satisfaction, the indicators used are the Servqual testing model, namely Tangible, Reability, Responsiveness, Assurance, and Empathy. Based on the level of accuracy of the two methods. In the dataset used there were 91 student respondents who had filled out the questionnaire. From the questionnaire data, it was then processed using both methods and 9 comparisons of the different Training Data and Testing Data were carried out. In general, students are satisfied and understand the use of the edlink application. This satisfaction was tested using the C4.5 Decision Tree Algorithm and the Naïve Bayes Classifier. Based on the comparison that has been carried out using the C4.5 Decision Tree Algorithm, it produces an average accuracy value of 77.78%, which is slightly more accurate than the Naïve Bayes Classifier which produces an average accuracy value of 71.11%.

Kebutuhan peralatan praktek bagi Sekolah Menengah Kejuruan (SMK) adalah suatu hal yang mutlak, akan tetap beberapa sekolah dengan keterbatasan hal tersebut bisa disiasati dengan pengunaan aplikasi simulasi. Untuk jurusan Teknik Komputer dan Jaringan (TKJ) aplikasi simulasi yang bisa digunakan untuk mengatasi keterbatasan alat praktek jaringan adalah Cisco Packet Tracer. Pelatihan ini ditujukan pada siswa kelas X untuk mengatasi keterbatasan alat praktek di SMK Migas Inovasi Riau kota pekanbaru, semua peserta diberikan pelatihan dasar jaringan, fitur dari aplikasi cisco packet tracer dan praktek merencanakan dan membuat jaringan komputer, pada akhir kegiatan diberikan mini projek mendesain jaringan komputer untuk gedung 2 (dua) lantai. Dalam 1 (satu) hari pelaksanaan peserta antusias mengikuti pelatihan dan mampu menyelesaikan tugas mini projek yang diberikan. Terjadi peningkatan pengetahuan untuk desain jaringan dan konfigurasinya dengan aplikasi simulasi ini sebesar 100%, sementara untuk materi pelatihan 98% peserta dapat menerima dan menerapkannya, sedangkan untuk pemateri menurut peserta 99% menguasai materi dan menyampaikan materi dengan baik serta mudah dimengerti.

This study discusses strategies for identifying Diabetic Retinopathy (DR) using fundus images and the efficiency of image pre-processing techniques to improve their quality. Fundus images in medical image processing often experience problems with non-uniform lighting, low contrast, and noise, thus requiring pre-processing of images to improve their quality. This study evaluates the effectiveness of standard histogram equation techniques and optimized histogram equations with cukkoo optimization in order to choose the best technique to improve fundus image quality to identify DR. The proposed technique to produce better image quality improvements will be tested in several performance metrics, such as NIQE, PSNR, and Entropy. the results of this study, the average PNSR before optimization was 50,8, whereas after optimization it became 49,8239. The average entropy before optimization is 4.5514, while after optimization it becomes 3.8577. The average NIQE before optimization was 3,4046, while after optimization it was 4,73. In general, the results of this study indicate that the quality of the fundus image is better using the histogram equation before optimization than after optimization. In other words, Cukcoo optimization is not suitable for increasing the performance of the histogram equation in improving fundus image quality

The most common factor contributing to visual abnormalities that result in blindness is known as diabetic retinopathy (DR). Retinal fundus scanning, a non-invasive method that is integral to the picture pre-processing phase, can be used to identify and monitor DR. Low intensity, irregular lighting, and inhomogeneous color are some of the main issues with DR fundus photographs. Analysis of aberrant characteristics on retinal fundus images to identify diabetic retinopathy is one of the key responsibilities of image enhancement. However, a variety of approaches have been created and it is unknown whether one is best suited for use with images of the retinal fundus. This study investigated various image enhancement methods in order to see aberrant abnormalities on retinal fundus pictures more clearly. This study investigated various image enhancement methods in order to see aberrant abnormalities on retinal fundus pictures more clearly. The contrast-limited adaptive histogram equalization (CLAHE) method, the gray-level slicing method, the median filtering method, and the low light method are image improvement methods used to enhance images of the retinal fundus. The parameters Natural Image Quality Evaluator (NIQE), Mean Squared Error (MSE), Peak Signal-to-Noise Ratio (PSNR), and entropy will be used to assess each image enhancement technique's performance. An ophthalmologist from Sains University Hospital (HUSM) provided the image data. The findings indicate that while each technique has its own benefits, the CLAHE technique, with a standard deviation MSE of 0.0004, is the best.
