Abstract

The application of information technology in the library can increase the acceleration of information to the public. One of the library activities that quite a lot of using paper media is borrowing books. The use of ledgers in borrowing books is tantamount to spending a lot of paper with large data and will cause piles later. Therefore, it is necessary to update the book lending system with integrated information technology in order to increase efficiency and effectiveness in the library. The Book Borrowing System or known as TEMANKU is a book lending system that is integrated with the internet to improve operations in book lending activities in the library. In carrying out this activity, a method must be used to implement it. The waterfall method was chosen because it is easy to implement and the system implementation can be implemented in a better and structured manner. On the other hand, the approach used in the design uses data flow diagram ( DFD). The results of this study resulted in the design of a website-based book lending system.

Abstract

Bisnis Tematik (Totebag Motif Wayang dan Batik) adalah inovasi bisnis untuk mengurangi sampah plastik dan pencemaran lingkungan karena pewarna sintetis/buatan. Selain itu, Tematik dapat dijadikan sebagai upaya untuk melestarikan budaya Indonesia seperti wayang dan batik yang terus menurun peminatnya akibat menyebarnya budaya asing sebagai dampak dari perkembangan teknologi yang begitu pesat. Untuk mengetahui apakah produk Tematik memiliki potensi penjualan yang tinggi, maka perlu dilakukan analisis peluang bisnis Tematik. Penelitian ini bertujuan untuk mengetahui peluang produk Tematik di pasaran dengan menentukan pasar sasaran yang berpotensi untuk pengembangan produk dan mendeskripsikan kondisi pasar Tematik di Indonesia. Metode penelitian yang digunakan dalam pembuatan totebag ini berupa pengumpulan data (primer maupun sekunder) untuk dilakukan analisis pasar melalui kuesioner, observasi, dan studi literatur. Hasil analisis yang telah dilakukan menunjukkan sebanyak 94% dari 140 responden belum pernah melihat perpaduan motif wayang dan batik shibori pada totebag, sehingga sebanyak 77 responden merasa tertarik untuk membelinya. Adapun hasil analisis Google Trends dari bulan Agustus 2021 sampai dengan Agustus 2022 menunjukkan bahwa dalam kategori belanja, hasil penelusuran web dengan keywords “totebag” cenderung mengalami peningkatan dengan pencarian totebag tertinggi di Indonesia ada di Daerah Istimewa Yogyakarta. Jumlah target konsumen melebihi jumlah produksi Tematik perbulannya yaitu 80 unit. Berdasarkan hasil analisis peluang Tematik tersebut, dapat disimpulkan bahwa Tematik layak untuk dijadikan usaha dan memiliki peluang pasar yang baik untuk memulai bisnis Tematik.

Abstract

Hepatitis has become a public health problem that is generally caused by infection with the hepatitis virus. One type of hepatitis caused by a virus is Hepatitis C. This disease can cause patients to experience inflammation of the liver. In the worst conditions, it can even lead to death. Initial predictions need to be made to increase the awareness of each individual against the threat of Hepatitis C by using the K-Nearest Neighbor method. K-Nearest Neighbor is a classification method that can give a pretty good percentage result in classifying, especially when using large training data. However, K-Nearest Neighbor still has a weakness, namely the determination of the value of K that is less precise so that it can reduce classification performance. To overcome these shortcomings, the researchers used the implementation of Particle Swarm Optimization on K-Nearest Neighbor to find the optimal K value. The existence of this implementation is expected to be able to increase the value of accuracy in classification and overcome solutions to weaknesses in the K-Nearest Neighbor algorithm. From the results of the K-Nearest Neighbor test, the accuracy value is 97.24% at K=5 and K=3. As for the results of testing the implementation of Particle Swarm Optimization on the K-Nearest Neighbor, there was an increase in the accuracy value of 2.07% to 99.31%. This test shows that the implementation of PSO can overcome the shortcomings of KNN and this model can be used as the best solution to determine the classification of Hepatitis C disease.
