Abstract

In several previous studies, smart devices have been developed to help improve a patient's medication adherence but have problems, namely data management that is not centralized and not integrated, so that mitigation is quite vulnerable. In this study, a platform was built that can manage data centrally and apply the FHIR (Fast Healthcare Interoperability Resources) health data standard. The main components used to implement the FHIR standard are resources and REST APIs. The resource is a data model that defines the structure and data elements that are exchanged. This data exchange is carried out on top of the REST API using the HTTP protocol. Platform testing uses positive/negative testing and stress testing methods to be able to see the performance of the platform. The test results show that the platform prototype can provide a response that is in accordance with the request given and has a very tolerant error value of 0% with a latency value of 3 to 22 seconds with a total of 100 to 130 users.

Organisasi industri farmasi pada proses produksi obat dan bahan obat berupaya untuk melakukan monitoring operasional kegiatan mengenai kerusakan mesin, persediaan, perubahan product mix, meminimalkan kemacetan produksi, dan penjadwalan pesanan bekerja melalui pabrik. Selain itu, diharapkan konsep green environment pada proses produksi obat dan bahan obat dapat meminimalisasi konsumsi kertas. Dalam hal ini, teknologi informasi (TI) dapat digunakan dalam proses penjadwalan, melakukan pengendalian tentang kualitas produk, serta berperan dalam mengatur persediaan dan memberikan laporan mengenai seluruh proses bisnis yang terjadi dalam organisasi. Selain itu, integrasi TI bertujuan menggabungkan sistem informasi yang tadinya terpisah untuk sebuah sumber daya informasi yang lebih lengkap dan menyeluruh bagi organisasi industri farmasi. Tetapi, besarnya dana atau anggaran yang dibutuhkan untuk mengimplementasikan teknologi sampai dengan pembiayaan pemeliharaannya menjadi masalah. Service Oriented Architecture (SOA) merupakan solusi alternatif untuk mengatasi masalah-masalah pada perusahaan industri farmasi. SOA menawarkan sebuah infrastruktur yang baik dengan kemampuan integrasi yang sudah terkelola, dan tentunya akan berdampak pada meningkatnya reliability, kemudahan pertukaran informasi antar aplikasi, mengurangi pengaruh jika terjadi perubahan, dan tentu dapat menekan biaya-biaya untuk keperluan integrasi dan modifikasi aplikasi. Model rancangan SOA dibuat mengikuti proses bisnis proses produksi obat dan bahan obat yang didasari oleh dokumen pedoman Cara Pembuatan Obat yang Baik (CPOB). Hasilnya membuktikan bahwa rancangan SOA dapat digunakan untuk membangun aplikasi proses produksi obat dan bahan obat serta dapat menjadi layanan untuk sistem lain bertukar data.

Abstract

Footstep recognition is relatively new biometrics and based on the learning of footsteps signals captured from people walking on the sensing area. The footstep signals classification process for security systems still has a low level of accuracy. Therefore, we need a classification system that has a high accuracy for security systems. Most systems are generally developed using geometric and holistic features but still provide high error rates. In this research, a new system is proposed by using the Mel Frequency Cepstral Coefficients (MFCCs) feature extraction, because it has a good linear frequency as a copycat of the human hearing system and Artificial Neural Network (ANN) as a classification algorithm because it has a good level of accuracy with a dataset of 500 recording footsteps. The classification results show that the proposed system can achieve the highest accuracy of validation loss value 57.3, Accuracy testing 92.0%, loss value 193.8, and accuracy training 100%, the accuracy results are an evaluation of the system in improving the foot signal recognition system for security systems in the smart home environment.
