Abstract

Hospitals are one of the health facilities that serve patients with various types of services, including BPJS patients. Like other hospitals, the queue system is a challenge in service management, especially in outpatient services. The imbalance between the number of patients coming and the service capacity can cause long waiting times. In this study, outpatient queue modeling was carried out at Leimena General Hospital, Ambon, using Petri Net to describe the service flow, and Max-Plus algebraic analysis was applied to estimate patient waiting times more accurately. The simulation results showed that increasing the number of resources, such as adding registration counters and doctors in the laboratory, was able to significantly reduce patient waiting times at various stages of service, especially in the pharmacy. This modeling shows that the Petri Net and Max-Plus approaches are not only effective in mapping the queue system, but can also be used as a basis for decision making in optimizing hospital services. This study is expected to be a reference for hospitals in improving service efficiency and for further researchers to develop more complex models by considering additional relevant variables.

Abstract

Citra merupakan suatu bentuk informasi yang memiliki peranan yang cukup penting. Citra dapat berbentuk 2 dimensi seperti gambar, foto, ataupun lukisan. Citra sendiri sering digunakan oleh masyarakat untuk keperluan sehari-hari, mulai dari untuk hiburan sampai untuk pekerjaan. Citra dapat digunakan sebagai hiasan atau juga dapat digunakan sebagai sumber mata pencaharian, seperti contohnya foto, video, iklan, dan lain-lain. Kamera digital, CCTV, ataupun dashboard merupakan tools atau alat yang biasa digunakan untuk menangkap citra atau gambar. Namun, dalam proses akuisisi, transmisi, dan penyimpanan, citra digital sering kali terkontaminasi oleh noise. Noise adalah gangguan acak yang mempengaruhi nilai piksel dalam citra, menyebabkan distorsi visual dan mengurangi kualitas citra secara keseluruhan. Beberapa jenis noise yang umum ditemukan dalam citra digital termasuk Gaussian noise, salt-and-pepper noise, dan speckle noise. Noise atau kebisingan yang melekat pada gambar perlu ditangani dengan cara mereduksinya agar lebih jelas dengan metode filter mean arithmatic yang dapat mengurangi noise pada gambar gambar digital jauh lebih jelas setelah dikurangi. Penelitian ini bertujuan untuk menguji keefektifan metode ini dalam mereduksi noise pada citra sehingga menghasilkan citra atau gambar dengan kualitas yang lebih baik. Pada penilitian ini digunakan dua ukuran filter pada Arithmetic Mean Filter, yaitu ukuran 3x3 dan 5x5. Hasil yang diperoleh bahwa bahwa hasil denoising menggunakan filter 3x3 lebih baik dibandingkan dengan menggunakan filter 5x5. Dimana pada filter 5x5, gambar hasil denoise menjadi blur atau kabur dibandingkan pada gambar hasil denoise menggunakan filter 3x3.
