Problems that<br>arise in the beginning of each learning year is the occurrence of a schedule that collides with several students<br>teacher. Starting from the background of the existing problems, the author designed the System Web-based<br>information to be implemented for scheduling processing teaching at the NU Al Ma'ruf Kudus High School. In this<br>study, the Genetic Algorithm method used to build a scheduling information system by completing complex<br>optimization problems, which are difficult to perform by conventional methods. Results research shows that the<br>Genetic Algorithm method can be used to build a teaching scheduling system. By generating a different task_ID<br>consists of subjects and teachers to produce the best fitness values in the shortest time short. From testing by<br>generating as many as 10 chromosomes and 25 generations the best fitness value = 0.024, time = 126.99<br>seconds, in the 12th generation.</p> Nor Wahyono Agus Subhan Akbar Joko Minardi Copyright (c) 2022 Journal of Information System and Computer 2022-07-31 2022-07-31 2 1 1 14 10.34001/jister.v1i2.267 SISTEM INFORMASI MANAJEMEN ASET MENGGUNAKAN METODE DEPRECIATED REPLACEMENT COST DI SATKORDIKCAM JEPARA https://journal.unisnu.ac.id/JISTER/article/view/286 <p><em>Learning support equipment is a very important main component in an educational process, because the learning process uses tools to facilitate the educational process. SATKORDIKCAM is this government agency that regulates education in the sub-district area, so in every sub-district there will be a similar institution, because SATKORDIKCAM controls education in the sub-district area it regulates and has various tasks, one of which is in the field of goods management, namely by fostering, supervising and control the state property owned, and must document and manage the goods in their environment. The documentation process which consists of supervising and controlling the goods is a form of management so that the condition of the goods can be known. The status of the goods or conditions in question include the position of the goods, the condition of the goods, the current price of the goods, and the service life of the goods. Submission of web-based information can make it easier to access information on goods anywhere and anytime online. Making it easier for the admin to carry out the asset management process and the calculation of asset depreciation.</em></p> Muhammad Alfianto Wisnu Prasetyo Noor Azizah Heru Saputro Copyright (c) 2022 Journal of Information System and Computer 2022-07-30 2022-07-30 2 1 15 22 10.34001/jister.v2i1.286 OPTIMALISASI METODE NAIVE BAYES DAN DECISION TREE UNTUK MENENTUKAN PROGRAM STUDI BAGI CALON MAHASISWA BARU DENGAN PENDEKATAN UNSUPERVISED DISCRETIZATION https://journal.unisnu.ac.id/JISTER/article/view/257 <p><em>Higher Education is a place for providing education that aims to produce quality human resources and is able to face increasingly fierce job competition. Therefore, from the recruitment process or the admission process, prospective new students must consider various procedures that aim to be able to direct prospective new students in determining the study program that will be taken by prospective new students. The things that have been broken in the admission process for new students include the scores of national exam results, report cards, school test scores and the admission test for new students, as well as the admission process of the achievement path and aiming for missions. From these things, performance must be improved is a supporting factor so that the process of transforming educational science to students can be carried out properly. The purpose of this study is to obtain classification in determining the study program of prospective new students by optimizing the Naïve Bayes and Decision Tree methods with an Unsupervised Discretization Approach, as an effort to improve the internal quality assurance system, especially the standards for the admission process for new students in determining study programs at the Harapan Polytechnic with Tegal. Where in the process of accepting new students, planning, implementing, evaluating, and monitoring have been carried out as a form of implementing the Internal Quality Assurance System (SPMI). In this study, the data used was data on the results of the admission of prospective new students from all study programs. These data include data on the administrative completeness of the requirements of prospective new students, as well as data on the value of the results of the new student admission test. The data used is data for 1 academic year 2019/2020. From this data, training and testing will be carried out using Rapidminer 9, a classification of lecturer teaching performance will be obtained.</em></p> Wildani Eko Nugroho Heru Saputro Copyright (c) 2022 Journal of Information System and Computer 2022-07-30 2022-07-30 2 1 23 31 10.34001/jister.v1i2.257 SISTEM INFORMASI PERSEDIAAN BARANG DENGAN SAFETY STOCK https://journal.unisnu.ac.id/JISTER/article/view/265 <p><span class="fontstyle0">Inventory is important for a business.

Persediaan yang tidak memenuhi permintaan akan mengecewakan konsumen karena pengadaan yang lama serta produk yang tidak laku di tempat persediaan menumpuk karena penjualan yang minimum maupun jenis atau merk barang yang sudah tidak update lagi. Tujuan dari penelitian ini adalah membuat aplikasi toko aksesoris handphone berbasis web yang dapat menentukan prediksi persediaan barang sehingga tidak terjadi penumpukan persediaan barang dengan menggunakan metode Double Exponential Smooting. Dengan menggunakan metode Double Exponential Smoothing menunjukan hasil yang bagus yaitu produk Tempered Glass warna dengan alfa sebesar 0,2 diperoleh nilai prediksi 4.441 pada bulan berikutnya dengan nilai MAPE sebesar 7%, sedangkan produk Tempered Glass bening dengan nilai alfa 0,6 diperoleh nilai prediksi 12.548 pada bulan berikutnya dengan nilai MAPE sebesar 3%. Dari pengujian nilai kesalahan prediksi pada kedua data dengan menggunakan perhitungan Mean Absolute Persentage Error (MAPE) menunjukan hasil yang sangat bagus karena memiliki tingkat error di bawah 10%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa aplikasi telah berhasil menerapkan metode Double Exponential Smoothing, sehingga dapat membantu dalam menentukan jumlah persediaan pada periode berikutnya agar tidak terjadi penumpukan persediaan barang.</p> Hidayatus Sibyan Caesar Dwi Kartika M.
