Lampu dan AC perkantoran merupakan salah satu penyumbang terbesar dalam pemakaian energi listrik. Penggunaan lampu dan ac yang tidak efisien menimbulkan pemborosan listrik yang mengakibatkan tagihan listrik mahal. Penelitian ini bertujuan untuk membuat otomatisasi pada sistem penerangan dan penyejuk ruangan kantor. Metode yang digunakan adalah perancangan dan pembuatan hardware dan software. Hardware berupa panel yang terdiri dari arduino uno yang merupakan pusat kendali alat, driver relay ssr berfungsi sebagai saklar pada lampu dan ac, sensor infrared sebagai pendeteksi untuk menghitung jumlah orang yang masuk dan keluar ruangan yang menjadi dasar untuk meng-otomatisasi hidupnya penerangan dan penyejuk ruangan kantor. Lcd digunakan untuk monitoring status counter yang terdeteksi oleh sensor infrared. Software yang digunakan adalah arduino IDE yang dapat mengontrol proses input dan output. Setelah dilakukan pengujian terhadap sistem yang telah dibuat, didapatkan hasil bahwa alat ini mampu bekerja sesuai dengan tujuan yang di inginkan. Sistem ini bisa di terapkan dalam proses otomatisasi penerangan dan penyejuk ruangan kantor.
Background: Dengue infection is an arboviral disease that could lead to severe illness. The incidence of severe dengue will impact patients' financial aspects. As an important clinical feature, platelet level on admission day might contribute to the direct medical cost. Objective: This study aimed to examine the direct medical cost among patients with dengue fever (DF) or dengue hemorrhagic fever (DHF) in Yogyakarta, Indonesia. Methods: This study was a retrospective study conducted in two private hospitals in Yogyakarta, Indonesia. Participants included in this study were hospitalized patients diagnosed with DF or DHF. Data were extracted from medical records and finance departments in each hospital. Results: Among 174 dengue patients included in this study, the mean age of DHF patients (18.44 + 14.87) was lower than in DF patients (23.47 + 18.99). Patients with DHF (4.88 days) also showed prolonged hospitalization compared with DF (4.18 days) patients. In terms of medical cost, DHF patients need a higher dengue treatment cost, which is about 329.74 USD compared to 220.68 USD for DF patients in hospital 2. Mainly related to room charges, which increased by 9.48% in hospital 1 and 66.28% in hospital 2 compared with DF patients. Furthermore, DHF patients with thrombocytopenia on the first day of admission present higher medical costs in terms of laboratory fees (36.08%), medicine (18.17%), and total medical costs (9.84%). Conclusion: Severe form of dengue will contribute to economic burden. Therefore, prevention and adequate treatment are essential to reduce the prognosis of severe dengue and higher medical cost.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
