Penerapan Metode Term Frequency (Tf) - Invers Document Frequency (Idf) untuk Pencarian Sinonim Kata dalam Kamus Bahasa Dayak Ngaju Kalimantan Tengah

The available Bahasa Dayak Ngaju dictionary only in hardcopy form and only consisted of the list of words andthe meaning of them. The dictionary didn't provide the synonym of the word we are looking for. If we want toknow the paraphrase of one particular word, we have to do it manually by searching it on all of the list of wordsin the dictionary. Therefore, this research proposed to develope a Dayak Ngaju dictionary that provide wordsynonym search. We use Term Frequency (TF) - Invers Document Frequency (IDF) algorithm that will helpsynonym searching by comparing the term emergence in the meaning of the word that we are going to look thesynonym for in all of the meaning of the words listed on the dictionary. This method will calculate the weight inall the documents based on the input query. To evaluate the methodology accuracy, we used precision and recallmethod. The results showed that after searching synonym of 100 queries, we founded that 33 queries hadsynonyms with precision = 1 and recall = 1 and all the synonyms that are found are relevant based on expert'sjustification

Aplikasi Penjadwalan Mata Kuliah Jurusan Teknik Informatika Fakultas Teknik Universitas Palangka Raya Dengan Algoritma Genetika

Scheduling courses in informatics engineering is needed to arrange an optimalschedule so that there is no conflict when teaching courses. In this journal of informaticsengineering has a problem in making a schedule because of frequent clash of teachinghours and the room used.Based on the problem, then to solve the above problem is to use the geneticalgorithm method. The genetic algorithm method is used for scheduling optimization.The final result of this research is the website program of Scheduling Courses inthe Department of Informatics, Faculty of Engineering, Palangkaraya University, whichcan display information about course schedules and this will be a tool for departments toprocess scheduling data through the course scheduling application

The misuse of digital image images is increasing, data or information that is of a personal nature can easily be known by others who are not entitled through digital images. This can cause material and immaterial losses to people whose personal information is misused by others. Then the application applies the Rijndael algorithm to secure digital image images which contain information or data that is of a personal nature. In securing digital image images, Rijndael's algorithm is used to protect the information contained in the image, the algorithm runs with processes such as SubBytes, ShiftRows, MixColumns, and AddRoundKey. The methodology applied is data collection methods such as field studies and literature studies, then Waterfall software development methods (Communication, Planning, Modeling, Construction, and Deployment) for system desig

Rancang Bangun Perbaikan Faktor Daya Otomatis Berbasis Smart Relay pada Jaringan Tegangan Rendah Tiga Fasa

Power factor is one of the problems in the electric power quality improvement. Power factor value that is too low can result in some electrical equipment can not operate properly. In many ways, low power factor need not cost cheap. To assist in the use of power factor correction capacitor banks to provide reactive power in the system. To improve the power factor is low, then the study will be compensated automatically by using smart relay as a switch to the capacitor bank. Cosphi great start on system is 0,26 lag with the addition of 2,08-33 µF capacitor to cosphi be 0.99 Lag
