Abstract

COVID-19 is a disease that spreads relatively quickly. So that many victims are infected by this virus. There are various ways to diagnose the body's infection with the coronavirus. One of them with X-ray results. Detecting COVID-19 with the help of an X-ray sometimes has problems determining the location of the lesion because it is possible because of the large amount of noise in the image. Therefore, the X-ray results will be segmented images using the graph cut algorithm to analyze normal lungs and lungs infected with COVID-19. After obtaining the segmentation results in the form of binary images, the next step is to analyze using the box-counting method's fractal dimensions. From the fractal Dimension results, normal lungs have an average dimension of 1.7890, and lungs infected with COVID-19 have an average dimension of 1.5834. Normal lungs have dimensions larger than lungs infected with the coronavirus due to the lungs' covering by lesions or abnormal conditions in body tissues. This is what causes COVID-19 patients to have complaints of difficulty breathing.

Abstract

AbstractProject management is one of the analytical techniques used for planning, scheduling, and making decisions about activities. This is useful so that the project can be implemented optimally and efficiently. Project management can be done by optimizing the network. Network optimization is very important for the production of bottled drinking water (AMDK) "AETA" produced by the PDAM of Kota Madiun. The optimization of the bottled water production network in this study uses the Fuzzy Critical Path Method (FCPM) analysis technique. Optimization of this fuzzy network is carried out to find a critical path in the production of bottled drinking water in order to get an efficient time in the production of 4 types of bottled drinking water, namely glass, 1.5L bottles, 600mL bottles, and gallons. The results showed that gallon product packaging has a high level of efficiency. In this research, fuzzy data analysis uses trapezoidal fuzzy numbers for bottled drinking water production time. Meanwhile, CPM is used to obtain the most efficient critical path or time in the AMDK production. The combination of these two methods is very helpful in project management so that the scheduling of activity can be run optimally.Keywords: Critical Path method; fuzzy; optimization; project management; scheduling. AbstrakManajemen proyek merupakan salah satu teknik analisis yang digunakan untuk perencanaan, penjadwalan, dan pengambilan keputusan tentang kegiatan. Hal ini bermanfaat agar proyek dapat dilaksanakan secara optimal dan efisien. Manajemen proyek dapat dilakukan dengan mengoptimalkan jaringan. Optimalisasi jaringan sangat penting untuk produksi Air Minum Dalam Kemasan (AMDK) "AETA" yang diproduksi oleh PDAM Kota Madiun. Optimasi jaringan produksi AMDK dalam penelitian ini menggunakan teknik analisis Fuzzy Critical Path Method (FCPM). Optimalisasi jaringan fuzzy ini akan dilakukan untuk mencari jalur kritis dalam produksi air minum dalam kemasan guna mendapatkan waktu yang efisien dalam produksi 4 jenis air minum dalam kemasan yaitu gelas, botol 1.5L, botol 600mL, dan galon. Hasil penelitian didapat pengemasan produk gallon memiliki tingkat efisien yang tinggi. Dalam penelitian ini, data fuzzy menggunakan bilangan fuzzy trapezoidal untuk waktu produksi AMDK. Sedangkan CPM digunakan untuk mendapatkan jalur atau waktu kritis yang paling efisien dalam produksi AMDK. Penggabungan antara dua metode ini sangat membantu dalam manajemen proyek sehingga penjadwalan suatu aktivitas bisa berjalan secara optimal.Kata kunci: Critical Path method; fuzzy; manajemen proyek; optimasi; penjadwalan.
