Klasifikasi Citra Rontgen Covid-19 dengan menggunakan Deep Learning

Citra adalah representasi dari suatu obyek yang ditulis ulang pada suatu medium dengan nilai tertentu (intensitas) yang memiliki koordinat x dan y. Citra Rontgent merupakan salah satu jenis citra medis yang dapat digunakan untuk mendeteksi dan mempelajari suatu penyakit. Namun citra rontgen terkadang terlihat kabur sehingga sedikit sulit untuk mengintepretasi citra. Terlebih lagi adanya redaman sinar-X yang berbeda antara kelenjar pada jaringan yang normal dengan yang terpapar penyakit. Dengan mengimplementasikan deep learning dengan metode klasifikasi citra dapat memilah gambar berdasarkan ekstrasi fitur dan bobot pada jaringan syaraf tiruan. Ketika GPU yang dimiliki adalah AMD, salah satu cara agar dapat menjalankan Deep Learning menggunakan AMD adalah mnggunakan PlaidML.Tahapan yang dilakukan pada pelatihan dan pengujian adalah melakukan pre-procesessing, ektraksi fitur menggunakan lapisan JST VGG16 tanpa lapisan pengklasifikasi (konvolusi dan pooling) yang menghasilkan bottleneck.npy, kemudian membuat lapisan pengklasifikasi sendiri untuk melatih klasifikasi kelas covid dan normal menggunakan data bottleneck.npy.

Perbedaan Kadar Albumin Plasma Pada Pasien Sebelum Dan Setelah Menjalani Rawat Inap Di RSUD PROF. DR Margono Soekarjo Purwokerto

The malnutrition rate in Indonesian hospital was hightly about 75%. The determinant of nutrition states with biochemically known by the concentration of plasma albumin. Albumin is the protein of the highest concentration in plasma. Albumin transports many small molecules in the blood (for example: bilirubin, calcium, progesterone, and drugs). It is also of prime importance in maintaining the oncotic pressure of the blood (that is, keeping the fluid from leaking out into the tissues). Decreased albumin may also be caused by malnutrition or a low protein diet. The aims of this research was to determine change in albumin before and after hospitalization in Margono Soekarjo Hospital, Purwokerto. It was analytic research with cross sectional study. The study population consisted of 69 subjects. The albumin concentrations was determined at before and after hospitalization. The average of albumin concentrations before and after hospitalization were 2,88 g/L and 2,52 g/L respectively. The t test showed that albumin concentrations after hospitalization decrease significantly (

Keefektifan ekstra putih telur terhadap peningkatan albumin dan penurunan IL-1β pada pasien tuberkulosis dengan hipoalbuminemia

Background: Tuberculosis (TB) is world health problem which still needs attention. Recently, Indonesia ranks the third in TB prevalence after India and China. Research revealed that albumin decreases significantly in TB patients, due to lack of nutritious intakes such as low-calorie intake, anorexia, increased catabolism, enteropathy and acute protein reaction. Low albumin was associated with increased IL-1β and cytokines inflammation in TB patient. Albumin had a very important role in the body and white egg known as a good quality source of protein.Objective: To assess the effect of white egg supplementation in TB patient towards the level of albumin and the level of IL-1β.Method: A single-blind randomized controlled trial was conducted with 75 patient selected for the study and divided to 37 patient as the study group and 38 as a control group. Both groups received high energy high protein diet, while the study group received, additionally, an oral egg white-based on formula calculation Baxter for 14 days. Control group received, additionally, an extra soybean curd and mungbean powder. Albumin and IL-1β were checked before and after the intervention. Data is analyzed by using Mann-Whitney.Results: Research results show that average albumin pre-intervention in the study group was 2.82 g/dL and control group was 2.85 g/dL. Average albumin difference in the study group was 3.47 g/dL and control group was 2.81 g/dL. Bivariate analysis results show significant of increasing albumin between study group and control group (p<0.05). Research results show average IL-1β pre-intervention difference in study group (0.9 pg/mL) and control group (0.67 pg/mL). The average IL-1β difference in the study group was -0.39 pg/mL and control group was 0.76 pg/mL. Bivariate analysis results show a significant difference of IL-1β depletion between study group and control group (p<0.05).Conclusion: Egg white increase albumin level and IL-1β depletion in tuberculosis patients effectively
