The Region of interest (ROI) of the fundus photography is an important task in medical image processing. It contains a lot of information related to the diagnosis of the retinal disease. So the determination of this ROI is a very influential first step in fundus image processing later. This research proposed a threshold method of segmentation to determine ROI of the fundus photography automatically. Data to be elaborated were the fundus photography’s of 13 patients, captured using Nonmyd7 camera of Kowa Company Ltd in Dr. M. Djamil Hospital, Padang. The results of this processing could determine ROI automatically. The automatic cropping successfully omits as much as possible the non-medical areas shown as darkbackground, while still maintaining the whole medical areas, comprised the posterior pole of retina captured through the pupil. Thus, this method is helpful in further image processing of posterior areas. We hope that this research will be useful for researchers.
Abstrak -Penggunaan jaringan komputer berskala besar yang ada saat ini terbentur masalah biaya yang mahal dalam pengadaan dan pemeliharaan perangkat keras (hardware). Hal ini mendorong perkembangan teknologi jaringan komputer yang hemat sumber daya, tempat, dan biaya. Teknologi jaringan komputer tanpa hardisk (diskless) menjadi jawaban akan permasalahan ini. Namun bagaimana dengan kualitas layanan yang menjadi isu utama dalam trend jaringan komputer. Penulis memanfaatkan teknologi jaringan tanpa disk (diskless) menggunakan PXE Linux yang bersifat opensource dipadukan dengan konsep Quality of Service (QoS) dapat mengurangi konsumsi daya dan biaya serta dari segi pemakaian bandwidth menjadi efisien dan efektif. Optimalisasi kualitas layanan dengan mengatur penggunaan bandwidth jaringan dapat diterapkan dengan teknologi Multi-Protocol Label Switching (MPLS) pada setiap paket data sehingga terarah sumber dan tujuannya. Kinerja teknologi MPLS pada jaringan diskless PXE Linux dengan parameter yaitu bandwidth, jitter, dan packet loss. Kata Kunci- Network Booting PXE Linux, Multi-Protocol Label Switching (MPLS), Quality of Service(QoS).
The background of this research is the geography teacher's perception of the Merdeka curriculum, which has not been implemented evenly in all SMA schools in Solok Selatan district. The purpose of this research is to find out the perceptions of teachers seen from their absorption, understanding and evaluation of the independent curriculum at SMA Solok SelatanThe type of research used in this research is descriptive. The population in this study were all geography teachers at SMA Solok Selatan, totaling 17 geography teachers. In this study using total sampling. The sample in this study were all geography teachers in Solok Selatan district. data analysis techniques in this study using descriptive analysis techniquesBased on the results of this study, it can be concluded that 1). Teacher perceptions seen from the absorption of the independent curriculum at Solok Selatan High School have a percentage of 87% with good qualifications. 2). The teacher's perception seen from the understanding of the independent curriculum at Solok Selatan High School has a percentage of 85% with a Good qualification. 3). Teacher perceptions seen from the assessment or evaluation of the independent curriculum at Solok Selatan High School have a percentage of 83% with good qualifications.
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.
