Abstract

Keberadaan perangkat elektronik tidak dapat dilepaskan dari sistem catu daya. Salah satu bagian dari sistem tersebut adalah regulator tegangan  yang berfungsi menghasilkan tegangan keluaran DC stabil pada nilai tertentu. Untuk tegangan keluaran positif 5 Volt, jenis regulator yangumum digunakan adalah IC L7805. Meski lembar data mencantumkan tegangan masukan maksimal untuk IC tersebut, nilai masukan minimum untuk menghasilkan keluaran 5 Volt stabil tidak diketahui secara pasti. Tujuan dari penelitian ini adalah mengetahui berapa nilai tegangan masukan minimum tersebut dan pengaruhnya terhadap regulasi tegangan. Percobaan pengukuran menggunakan sebuah rangkaian yang terdiri dari IC L7805, 2 buah kapasitor (0,33 µF dan 0,1µF), programmable DC power supply dan sebuah multimeter digital. Percobaan diulang tiga kali untuk kondisi tanpa beban (no load) dan berbeban (full load) sebesar 2KΩ, 4KΩ, 6KΩ, 8KΩ dan 10KΩ. Hasil-hasil percobaan menunjukkan bahwa tegangan masukan minimum untuk semua kondisi tersebut adalah 6,6 Volt. Jika tegangan masukan semakin turun dari nilai minimum, maka semakin besar nilai persentase regulasi dan ini menunjukkan kinerja regulator yang semakin buruk. Dalam perancangan rangkaian catudaya, untuk memastikan bahwa tegangan keluaran positif stabil pada 5 Volt, disarankan menggunakan tegangan masukan ke regulatorsekurang-kurangnya ±7 Volt.Keywords:tegangan masukan, regulasi, L7805, regulator

Abstract

This study was conducted to obtain an overview of the patient's level of trust in safety in the outpatient registration unit of IMC Bintaro hospital during the COVID-19 pandemic. The number of patients visiting IMC Bintaro Hospital decreased at the beginning of the pandemic, there where 55,101 people who registered outpatients in January-July 2019 while in January-July 2020 only 37,121 people (decreased 32%). This condition is thought to be due to the patient's concern about the transmission of COVID-19. The level of confidence research was carried out using a descriptive method in the outpatient registration unit of the IMC Bintaro Hospital, in February-April 2021. A randomly selected sample of 100 patients where registered in December 2020-February 2021. The technique of collecting data was by interviewing the head of the registration unit, observation, and an electronic questionnaire containing 10 questions related to the patient's level of confidence. The results showed that IMC Bintaro Hospital does not yet have an SOP for outpatient registration adapted to the pandemic conditions. However, health workers and registration areas have implemented health protection based on the Director's memo. While data from questionnaires to patients showed a high level of patient knowledge about COVID-19 (an average of 94.8% answered agree), accompanied by a high level of patient confidence in safety in the outpatient registration unit (an average of 88% answered agree). Most of the samples gave a positive response, they have received services in line with expectations. Patients feel safe for treatment at the IMC Bintaro Hospital during the COVID-19 pandemic. However, it should be understood that the sample was taken from patients who came to the hospital after the pandemic lasted for about 1 year, while number of patients who visited the hospital during the study was not carried out. Keywords: Level of trust, security. COVID-19 pandemic, registration unit
