The Weighted Product used multiplication to connected attribute ratings, where the rating of each attribute might be raised to the first power with the weight of the attribute in question. This process was the same as the normalization process. programming language Java and the database used MySQL.</em></p> <p><em>This system could generated a ranking alternatif exercise program Fitness body weight user Based on the system testing carried out, the system could&nbsp; to provided results in accordance with the calculations used, so that this system could assisted in determining fitness exercise recommendations.</em></p> <p>&nbsp;</p> Robby Rahmatullah Wahyu Adimahendra Copyright (c) 2022 Journal of Information System and Computer 2022-12-29 2022-12-29 2 2 1 7 10.34001/jister.v2i2.420 DATA MINING KLASIFIKASI KEPRIBADIAN SISWA SMP NEGERI 5 JEPARA MENGGUNAKAN METODE DECISION TREE ALGORITMA C4.5 https://journal.unisnu.ac.id/JISTER/article/view/392 <p><em>In the world of education, there are many supporting factors to achieve success in the learning process, from teachers, materials, to students.

Fulfillment of these information needs is carried out with the help of technology, especially in the field of computerization, such as in the field of the internet. In supporting the performance of UMKM, technological product innovation is needed to be developed and implemented, such as internet technology. Promotions carried out using internet technology are known as digital branding. Digital Branding plays an important role in the development of the use of information technology to provide information. The Waterfall model is one of the SDLC models that is often used in the development of information systems or software. This model uses a systematic and sequential approach. The use of the web in delivering information can make it easier to access information about UMKM anywhere and anytime online. Making it easier for UMKM products to be widely known.</em></p> Indra Kurniawan Yasa Maulana Muhammad Sulthony Ahmad Mubais Nur Hikmah Via Fitriana Putri Zeni Kurniati Copyright (c) 2022 Journal of Information System and Computer 2022-12-29 2022-12-29 2 2 14 19 10.34001/jister.v2i2.389 MENENTUKAN PREDIKSI REKOMENDASI BIMBINGAN KONSELING SISWA SEKOLAH MENENGAH KEJURUAN MENGGUNAKAN K-NEAREST NEIGHBOR https://journal.unisnu.ac.id/JISTER/article/view/409 <p><em>The problem of counseling guidance is one of the problems found in schools which is one thing that is difficult to predict. Accurate predictions are needed to support decision making for those who have policy in making decisions. One of the things that can be done to make predictions in providing guidance and counseling recommendations is to use the K-Nearest Neighbor method. Of the 388 students in the school, tests or experiments can be carried out using the K-Nearest Neighbor algorithm method. The results obtained from the experiment were 96.40% with 362 students who did not have to do counseling guidance, and 62 students who had to do counseling guidance. From the experimental results, it is hoped that the quality of the education system being carried out is expected to be further improved because it will affect the quality of the school.</em></p> Wildani Eko Nugroho Heru Saputro Copyright (c) 2022 Journal of Information System and Computer 2022-12-29 2022-12-29 2 2 20 24 10.34001/jister.v2i2.409 SISTEM PAKAR DIAGNOSA CEREBRAL PALSY PADA ANAK MENGGUNAKAN METODE CERTAINTY FACTOR https://journal.unisnu.ac.id/JISTER/article/view/391 <p>Kajian ini berisi rancangan penerapan metode certainty factor pada sistem pakar yang merupakan program kecerdasan buatan yang mampu meniru proses berpikir dan pengetahuan seorang pakar atau ahli dalam memecahkan suatu masalah tertentu. Cerebral Palsy adalah suatu gangguan atau kelainan yang terjadi bisa saat dalm kandungan atau pada masa tumbuh kembang anak, mempengaruhi menggambarkan kaskade motoric pada sistem saraf pusat, menahun dan tidak progresif yang tetjadi pengaruh gangguan kelainan atau cacat pada syaraf atau jaringan otak yang belum tumbuh pada perkembangan anak. di Kabupaten Wonosobo hanya ada satu tenaga medis dalam satu rumah sakit yang mampu mendiagnosa, kekurangan tenaga ahli dan pengetahuan dapat diatasi dengan perkembangan teknologi. Certainty factor adalah metode yang dipakai untuk memyelesaikan sebuah permasalahan ketidakpastian selalu terjadi, dengan secara langsung menentukan nilai/bobot pada kepastian suatu fakta atau rule, untuk memperkirkan tingkat kepercayaan pakar pada masalah yang akan dihadapi atau sedang dihadapi.</p> Kiki Rizki Amalia Hidayatus Sibyan Nahar Mardiyantoro Copyright (c) 2022 Journal of Information System and Computer 2022-12-29 2022-12-29 2 2 25 31 10.34001/jister.v2i2.391 PENERAPAN ALGORITMA A* PADA WEBGIS PENCARIAN RUTE TERPENDEK https://journal.unisnu.ac.id/JISTER/article/view/395 <p><em>Geographic information systems have been able to solve routing problems such as TSP (Travelling Salesman Problems) or finding the closest route. GIS has developed a lot into GIS applications, both in the form of desktop, web, and mobile. This research develops a webGIS application that can provide a solution for tourists who have difficulty reaching a furniture showroom in Jepara City. The method used is the A* algorithm. The algorithm can calculate existing nodes through heuristic calculations. Data from google maps are converted into a grid form, then calculations are carried out. This research produces an alternative shortest route, while the accuracy of Google Maps road data affects the displayed route search.</em></p> Alzena Dona Sabilla Ahmad Taufiq Copyright (c) 2022 Journal of Information System and Computer 2022-12-29 2022-12-29 2 2 32 35 10.34001/jister.v2i2.395 IMPLEMENTASI ALGORITMA APRIORI DALAM MENENTUKAN POLA PEMBELIAN (CAP N CHRIS CAFÉ & RESTO JEPARA) BERBASIS WEB https://journal.unisnu.ac.id/JISTER/article/view/393 <p><em>With the rapid advancement of technology at this time, there are many sales transactions received every day.
