Abstract

Research has been conducted on detecting tuberculosis (TB) using machine learning. In this study, chest Xray (CXR) image data was used with a pixel value of 512 x 512 and PNG format consisting of normal lung images and TBinfected lung images in a 50:50 ratio; the number of images was 200 training data images and 80 testing data images. In the preprocessing stage, grayscaling is carried out so the image has a grayscale. Then, do the image improvement using contrast stretching. Furthermore, image extraction was carried out using 22 GLCM features with variations in the direction of the angles of 0, 45, 90, and 135. The result of feature extraction data is then identified using KNN Classification. The training results have the highest accuracy value with variations in the direction of the GLCM angle of 45 and the value of K = 3; at the testing stage, it produces an accuracy of 90%.

Abstract

This study aims to examine computational (numerical) programs in solving the Ginzburg-Landau Time-Dependent Equation. The Ginzburg-Landau Time-Dependent Equation (TDGL), which is often used to model the dynamics of superconductors in external magnetic fields.  The TDGL equation is made using the Scilab platform, then the results are compared with the results of Fortran. This study involves experiments with variations in superconductor size to observe their effect on simulation results. The main focus of this study is to study the relationship between the mean magnetization of superconductors and external magnetic fields (He), as well as to evaluate the accuracy and efficiency of the results obtained from the two computing platforms.  These results show the relationship between the mean of the superconductor magnetization and the external magnetic field, as well as a comparison of the Vs He graph of Scilab and Fortran showing the relationship between the superconductor order parameters and the external magnetic field.

Abstract

Proton therapy modeling for treating craniopharyngioma tumors was conducted using a pencil beam collimator, and variations in beam directions were performed using MCNP6 software. The simulation was carried out on a head and neck phantom with the tumor cells modeled within a cubic irradiation area geometry with a 1.2 cm side length, divided into 27 small cubic voxels with a small voxel side length of 0.4 cm. The radiation source from the irradiation area's right, left, and top directions, with a diameter of 0.4 cm, was directed at each cubic voxel. Variation in radiation source directions indicated that irradiation from the right direction of the irradiation area is the most recommended approach, with a dose uniformity level of 83.47%. Healthy organs surrounding the irradiation area received lower doses than those obtained by tumor cells, and the majority remained below the Organ At Risk (OAR) threshold. Healthy organs received the highest dose, particularly in the brain region, at a relative 0.46% compared to the total dose received by tumor cells.

Abstract

A study has examined the characteristics of 3D printer materials of HIPS and PLA. The study began by printing HIPS materials that resembled breast organs and PLA materials that resembled breast cancer nodules. Then it exposed them using a CT scan with voltage variations of 80 kV, 100 kV, and 120 kV. The parameters studied were compared with the reference breast organ. The results obtained at these voltages obtained CT-number values sequentially (-85.14+0.25) ; (-64.79+0.21) HU; (-55.08+0.18) HU values from the reference 35 to -94 HU, relative electron density values sequentially 0.915; 0.935; 0.945 with a reference value of 0.950, the density value of the material obtained is (0.921+0.002) g/, The EDG value is 3.24 x  from ICRU 1989 was 3.33 x, The EDV value is (3.00 + 0.01) x  from ICRU report 44 was 3.18 x 10, the value is 3.50 the value of ICRU data is 3.28, and the effective dose values are respectively 2.53 mSv, 2.83 mSv, 3.20 mSv. Based on these characteristics, the results indicate that the breast phantom matches the characteristics of the breast organ, allowing it to be used to predict the presence of breast cancer, as it shares the same characteristics. The results of exposure to the lung cancer nodule phantom on the CT-Scan image of the 2 mm nodule size are not visible. The results of this study can be used as a consideration for radiologists when choosing a voltage based on the predicted size of the breast cancer nodule.

Abstract

Research in the field of radiodiagnostics has been extensively developed, creating the need for substitute objects to represent human organs—namely, radiological phantoms. A phantom is a simulated model of an organ fabricated using 3D printing technology. This study aims to evaluate the suitability of Expanded Polyamide – Glass Fiber (EPA-GF) as a kidney stone phantom material embedded within a kidney phantom, based on parameters such as material density, CT number, electron density, and radiation dose across various CT scan exposure voltages. The phantom samples were printed using a dual-extruder 3D printer, with Expanded Polycarbonate (EPC) used as the kidney phantom material. CT scan exposure voltages were set to 80 kV, 100 kV, and 120 kV. Kidney stone sizes used in this study ranged from 1 mm to 8 mm (1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, and 8 mm). The measured density of EPA-GF was 1.51 ± 0.06 g/cm³. The CT numbers obtained at each voltage were 373.30 HU, 329.05 HU, and 299.46 HU, respectively. The corresponding electron density values were 1.231, 1.210, and 1.196, respectively. The effective doses measured at each voltage were 0.0240 mSv, 0.0448 mSv, and 0.0798 mSv. All parameter values were found to be closely aligned with literature references. The smallest visible kidney stone size detected was 2 mm.

Abstract

Pneumonia has been detected using Machine learning. The stages in this study began with preprocessing in 4 stages: resizing, cropping, filtering using a high pass filter, and Adaptive Histogram Equalization. The feature extraction process continued with 22 Gray Level Co-occurrence Matrix (GLCM) features and classification using K-Nearest Neighbor (KNN). The image used was 150 data sets for training on the classification of 3 classes with a ratio of 50:50:50 while training on two classes was 50 bacterial pneumonia and 50 viral pneumonia. The most optimal training data accuracy results were obtained using the angle direction on the GLCM, namely 135o with the KNN classification (k = 3). For the classification of two classes Using 40 data sets, an accuracy of 91% was obtained, while testing for three classes with 60 data sets was 83.3%.

Abstract

Telah diimplementasikan sistem cerdas pengusir hama berbasis panel surya, Alat pengusir hama otomatis ini memanfaatkan gelombang ultrasonik dengan tiga pengaturan: 3–6 kHz untuk burung, 20–31 kHz untuk serangga, dan 31–50 kHz untuk tikus serta kelelawar. Suara yang dihasilkan bervariasi dari bising hingga tak terdengar oleh manusia. Alat ini menggunakan panel surya dan baterai internal, serta dilengkapi dua mode otomatis: siang (S) aktif saat terkena sinar matahari dan malam (M) saat gelap. Kedua mode dapat disesuaikan sesuai jenis hama dan waktu penggunaan, sehingga mendukung efektivitas pengendalian hama secara berkelanjutan. Alat ini telah terpasang di Desa Wonorejo selama periode pemsasngan sudah memberikan dampak yaitu berkurangnya burung dan tikus disekitar lokasi pemasangan alat dan dengan harapan ada peningkatan kuantitas panen petani.

Abstract

Kegiatan pengabdian berupa pelatihan alat peraga kelistrikan dan kemagnetan  merupakan salah satu upaya untuk mengatasi permasalahan dalam pengajaran sains sejak dini. Selama ini, anak-anak diajarkan sains melalui cerita, yang membuat mereka bosan berakibat mereka kurang memahami sains. Dalam kegiatan ini dilkaukan pelatihan pemanfaatan sains sejak dini melalui praktek penggunaan alat peraga kelistrikan dan   kemagnetan bagi guru tingkat Sekoalh dasar. Kegiatan dimulai dengan pretest untuk mengetahui kemampuan peserta pelatihan diperoleh nilai rerata 69, kegiatan dilanjutkan dengan pengenalan konsep teori dan praktik alat peraga kelompok. Diakiri dengan praktek pemanfaatm alat peraga kelistrikan terkait dengan rangkaian seri dan paralel dan untuk kemagnetan dengan pengenalan magnet statis dan dinamis.  Hasilnya adalah peserta menunjukkan tingkat pemahaman yang lebih baik terbukti dengan hasil postest dengan nilai rerata adalah 84. Kata kunci: alat peraga; saintek; percobaan; listrik; magnet
