Peminjaman buku merupakan salah satu wujud pelayanan yang diberikan oleh perpustakaan. Peminjaman sangat erat kaitannya dengan persediaan. Pada perpustakaan A dalam menentukan persediaan buku, pegawai perpustakaan kesulitan untuk menentukan jenis-jenis buku apa saja yang sangat dibutuhkan mahasiswa. Dimana penentuan jumlah dan jenis buku belum menggunakan sistem perhitungan yang pasti, hanya berdasarkan perkiraan jumlah mahasiswa dan matakuliah setiap program studi. Maka dari itu dibutuhkan klasifikasi peminjaman jenis buku berdasarkan transaksi peminjaman buku mahasiswa, data yang digunakan dalam penelitian ini yang sebanyak 269.116 dari tahun 2014 sampai 2019 bulan ke 6. Data jenis buku yang diolah sebanyak 184 jenis buku dari 1700 jenis buku, tahapan pertama yang dilakukan melakukan teknik forecasting untuk meramalkan target persediaan setiap jenis buku pada tahun selanjutya, tahapan kedua data transaksi peminjaman buku diproses untuk mengetahui klasifikasi jenis buku dengan menggunakan neural network backpropagation. Didapatkan hasil tingkat error atau MSE sebesar 0,021, menggunakan layer hidden 9 dan fungsi aktivasi tansiq dengan epoch 2000, dengan rekomendasi jumlah jenis buku yang disarankan untuk restock sebanyak 86 jenis buku dengan jumlah prediksi disetiap jenis buku. Tahapan ketiga melakukan pengujian validasi data untuk mengetahui tingkat error klasifikasi dan prediksi, terakhir dilakukan uji regresi menunjukan hasil hubungan yang siqnifikan sebesar 0,006 dengan data variabel yang dujikan yaitu data prediksi, klasifikasi dan target.. Hasil dari penelitian ini adalah dapat memberikan data rekomendasi jenis buku beserta jumlah prediksi di setiap jenis buku yang dibutuhkan ditahun yang akan datang dengan menggunakan metode neural network backpropagation dengan tingkat akurasi sebesar 95,5%.

Pacman is an arcade game developed by Namco and released in Japan on May 22, 1980. Pac-Man, which is still popular today, has also been released on other platforms such as Game Boy and SNES. The designer of this game is Toru Iwatani, who is a Namco employee. The concept of the game in the Pacman game is very simple: Players must control the Pacman character to eat all the small dots and other special objects that are in the maze without being caught by 4 ghosts. The greedy algorithm is used to find the current shortest path from the position of the ghost character to the position of the Pacman character.

Artificial intelligence is an important factor in games between humans against computers (NPC = Non-Character Player). One method of artificial intelligence that can be used is the Breadth First Search (BFS) algorithm and fuzzy logic. This study chose the classic Pac-Man game, in the game the Pac-Man BFS algorithm was applied to the process of finding and pursuing Pac-Man. For fuzzy logic, the Sugeno method is used when making decisions, namely ghost behavior in the game. The methodology used is the prototype methodology. In the testing process, the BFS algorithm is used in the black box testing technique, while the Sugeno fuzzy logic method is used to compare computation testing during decision making. With the testing process, it can be drawn that the appropriate BFS algorithm to find the shortest path while pursuing Pac-Man and Sugeno Fuzzy Logic method can be used for ghost behavior decision making with search speed 10 times faster than DFS algorithm.

Resource center (RC) or can be called also in this case is a library. The library is a place to study or to access information. The RC system of Amikom Yogyakarta University has attendance services for visitors from the user side, namely internal students and external visitors and stores visitor data to find out how many people visit the library, both internal and external visitors. Usability problems that usually appear in system features for users, indicate the need for usability testing. Usability testing uses the SUS (System Usability Scale) method in order to find problems with the visitor attendance system by referring to usability principles, which can involve users. This research was conducted in 3 main stages, namely compiling a questionnaire in accordance with the provisions of the SUS method, processing the results of the respondents' answers from those distributed to visitors by the SUS method rules to obtaining test results in the form of SUS scores. Based on the results of the evaluation carried out, the average SUS score from the study was 55.56, which means it has a D rating (less) which indicates that the presence system visitor feature cannot be accepted by users from the usability aspect, it is still minimal in use, because it only stores visitor data, the recommendations given from the results of this evaluation in order to increase usability for visitor features are such as visitor entry hours, exit hours, input facilities in the form of input related to collections of books, journals, magazines, e-books, facilities inside, room atmosphere, and others, because things like this affect the optimal library services for visitors.

At CV. Nabila Zafira Mahali (Nazma) the daily recap of the work of the creative team still uses Google Excel which is prone to data manipulation by people who are irresponsible and don't have a good history of data records, if someone makes a mistake. Recap for monthly reports takes quite a long time, if there is an error in awarding honorarium or there is data that is not appropriate then it is not immediately known by management, the creative team's daily work report has an indirect relationship to the finance department, or the part that regulates awarding honorarium, if the data entered is unclear or inappropriate, there will be a delay in awarding honorarium. Therefore training is needed in using the clickup application which can help the creative team's daily work recap. The process of implementing the training stages begins with an interview with director Nazma and documentation of the required data, followed by determining and creating training materials, and finally, continuing online training using Google Meet, with material using the click-up application, one of the template features, namely CRM (company management profile) in the template there is todo (work list), in progress (under construction), Ready (ready) and complete (finished) features, so that management can monitor the work of the creative team more clearly. In the results of the training evaluation, a score of 70% was obtained on the value of the questions on the benefits of training and project management control.
