Abstract

Along with the development of industry in Indonesia currently starting towards the industrial revolution 4.0, so the role of technology is needed, especially in the information processing. Data processing, and information precisely, quickly and efficiently are important things that are needed for every company or an agency to increase work productivity, save time and costs. The company's success in maintaining its business is also inseparable from the company's role in managing material inventory so that it can meet production needs as much as possible. This research was conducted at the warehouse department of the Cisumdawu Toll Road Development Project (Cileunyi - Sumedang - Dawuan) Phase 2 Section 2 which is done by PT. Wijaya Karya (Persero) Tbk. The study was conducted for 1 month, starting on August 13, 2019 until September 13, 2019. The results of the development of a Digital Business Eco-System (DBE) based inventory management information system using the System Development Life Cycle (SDLC) method can overcome existing problems namely, can facilitate data collection and data search work required. Based on the calculation results of the USE questionnaire system that has been developed to get an alpha cronbach value of 0.955, it can be concluded that the USE questionnaire has an internal consistency value of Excellent. While the percentage of usability calculation results obtained 88.67%, based on a qualitative scale, the results of the value conversion are "very feasible" and have met usability standards.Seiring dengan perkembangan industri di Indonesia saat ini yang mulai menuju revolusi industri 4.0, peranan teknologi sangatlah diperlukan khususnya di bagian pengolahan informasi. Pengolahan data, dan informasi secara tepat, cepat dan efisien adalah hal penting yang dibutuhkan bagi setiap perusahaan atau suatu instansi untuk meningkatkan produktifitas pekerjaan, menghemat waktu dan biaya. Kesuksesan perusahaan dalam mempertahankan bisnisnya juga tidak terlepas dari peran perusahaan tersebut dalam mengelola persediaan (inventory) material sehingga dapat memenuhi kebutuhan produksi semaksimal mungkin. Penelitian ini di lakukan pada departemen gudang Proyek Pembangunan Jalan Tol Cisumdawu (Cileunyi – Sumedang – Dawuan) Fase 2l Seksi 2 yang dikerjakan oleh PT. Wijaya Karya (Persero) Tbk. Penelitian dilakukan selama 1 bulan, dimulai pada 13 agustus 2019 sampai dengan 13 september 2019. Hasil pengembangan sistem informasi manajemen inventory bebasis Digital Business Eco-System (DBE) menggunakan metode System Development Life Cycle (SDLC) dapat mengatasi permasalahan yang ada yakni, dapat mempermudah pekerjaan pendataan dan pencariaan data yang diperlukan. Berdasarkan hasil perhitungan realibilitas kuesioner USE sistem yang telah dikembangkan mendapatkan nilai alpha cronbach sebesar 0.955, maka dapat disimpulkan bahwa kuesioner USE memiliki nilai internal consistency Excellent. Sedangkan presentase hasil perhitungan usability mendapatkan 88,67%,berdasarkan skala kualitatif, hasil dari konversi nilai adalah “sangat layak” dan telah memenuhi standar usability.

Abstract

— Kesehatan merupakan salah satu hak dasar manusia di Indonesia yang diakui dalam konstitusi UUD 1945. Sebagai perwujudan dari perlindungan hak dasar tersebut, Negara bertanggung jawab atas penyediaan fasilitas layanan kesehatan yang layak termasuk ketersediaan obat. Ketersediaan perbekalan kesehatan ini dilakukan melalui kegiatan pengadaan alat kesehatan. Alat kesehatan pada rumah sakit di suplai oleh banyak pabrik pembuat alat kesehatan khusus rumah sakit. Banyaknya jenis alat kesehatan membuat beberapa masyarakat dan para siswa sulit untuk mengenali serta memahami jenis alat kesehatan dengan mudah dan praktis. Media belajar berbasis aplikasi android dapat mempermudah sarana kegiatan dalam proses pembelajaran dan menambah wawasan tertentu. Ditinggalkannya gaya membaca pada media buku cetak saat ini membuat masyarakat beralih dalam mencari pengetahuan berbasis aplikasi android. Dengan dibangunnya aplikasi pengenalan alat kesehatan berbasis android diharapkan mampu membantu masyarakat dan para siswa untuk mempelajari jenis alat kesehatan secara interaktif. Para siswa dapat mengasah pengetahuan mereka dengan adanya kuis yang tersedia pada aplikasi. Untuk metode penelitian ini menggunakan metode prototyping. Hasil penelitian ini diharapkan agar pemahaman dan pengetahuan tentang jenis-jenis alat kesehatan dapat lebih mudah dimengerti serta difahami dengan baik dalam bentuk aplikasi berbasis android mobile.

Abstract

Data from WHO states that 7,3 million people die because of Heart Disease. Although Heart Disease is not contagious, this kind of disease is the number 1 disease causing death. Heart disease is also called as coroner disease. It happens when the blood drifting to the heart muscles stops so that it causes heart disorder (Rajkumar & Reena, September 2010). The application of Nearest Neighbor classification (K-NN) algorithm is expected to overcome the problems on the affectivity and accuracy in detecting heart disease. In this research, the K-NN with K = 9 is used on 100 patients of heart disease. The result revealed is that the accuracy is 70% and the AUC is 0.875 which belong to the good classification. Hence, K-NN algorithm can be used and applied in detecting heart disease. Keywords: Nearest Neighbor, Jantung, Algoritma, Akurasi.
