Abstract

Batu ginjal merupakan padatan yang terbentuk di dalam saluran kemih akibat adanya penggumpalan zat-zat organik dan non organik yang seharusnya larut di dalam urin. Batu ginjal harus dikeluarkan baik melalui urin maupun melalui terapi dan pembedahan. Sebelum dilakukan terapi atau pembedahan, perlu diketahui komposisi dan jenis batu ginjal yang diperlukan dalam penentuan diagnosis dan tindakan pengobatan yang tepat. Micro CT merupakan modality pencitraan yang dapat menunjukkan struktur anatomi dan morfologi batu ginjal berdasarkan nilai atenuasinya dengan ketelitian dalam orde mikro dibandingkan dengan CT konvensional biasa. Namun, terdapat kelemahan jika menggunakan single energy micro CT dalam pengelompokan batu ginjal. hasil citra pada energi tinggi tidak dapat membedakan dengan baik antara batu dengan densitas yang rendah dan tinggi namun dosis yang diterima pasien cukup rendah sehingga tidak membahayakan, dan sebaliknya untuk citra energi rendah. Dalam hal ini diperlukan metode dual energi untuk membedakan batu ginjal dengan tepat. Sebelum menggunakan metode dual energi diperlukan data perbedaan atenuasi batu untuk penyinaran berbeda. Oleh karena itu dalam penelitian ini dilakukan perhitungan untuk menentukan nilai atenuasi batu. Metode penelitian dilakukan secara komputasi menggunakan software PEGS4. Sebagai input data adalah komponen penyusun batu dan densitas batu. Hasil yang didapatkan adalah, pertama, dengan tingkat penyinaran berbeda, beberapa batu tidak dapat dikarakterisasi dengan menggunakan single energi saja. Atenuasi brushite dan struvite hampir sama, sehingga sulit untuk dibedakan. Kedua, single energi micro CT perlu dikoreksi menggunakan dual energi micro CT untuk mengelompokkan batu ginjal dengan tepat

Abstract

Kidney stones are a disease due to the buildup of substances that are not needed in the urinary system. Knowledge of the composition and type of stone is required in the treatment of action. Micro CT is one of the modalities that can be used in determining the composition of kidney stones. However, there are limitations when using single-energy micro-CT. Stone attenuation has almost the same value when using single energy, therefore it is necessary to use dual-energy CT to determine the difference in stone attenuation more precisely. The image of the dual-energy CT micro-energy stone needs to be processed before analyzing and determining the rock composition. Image fusion is one of the image processing techniques that can be used. The purpose of this study was to determine the effect of image fusion on the image quality of five kidney stones. The stages in the research carried out are collecting high energy and low energy projection image data, and performing image fusion on the two projected image data. The results obtained are first, the dual-energy CT image fusion affects the image quality which can be seen from the increase in the signal to noise ratio (SNR) value. A high SNR value provides the best image quality information

Abstract

Education plays a vital role in cultivating qualified future generations, with active student participation serving as an indicator of effective learning processes. Preliminary observations at SMP Negeri 32 Padang revealed low engagement levels in science classes, prompting the need for interventions to boost students' involvement. The primary objective of this classroom action research was to enhance student engagement in science learning activities through implementing the Discovery Learning model and Teaching at the Right Level approach in a Grade 8 classroom at SMP Negeri 32 Padang. The study was conducted over three cycles, each consisting of planning, acting, observing, and reflecting phases. Data on student engagement in science learning activities was collected through observations using a rubric. The initial data in Cycle I revealed low engagement at 36.72%. After implementing interventions integrating Discovery Learning activities and personalized scaffolding based on students' ability levels in Cycles II and III, student engagement progressively increased to 45.76% and 62.28% respectively. Surveys and interviews indicated students found the learner-centered, inquiry-based activities more enjoyable and effective for understanding compared to traditional instruction. The findings demonstrate the potential of combining Discovery Learning and Teaching at the Right Level methods to significantly improve learning participation by stimulating intrinsic motivation through autonomous exploration while providing individualized support. The research offers practical strategies for enhancing science education engagement and contributes to the Kurikulum Merdeka goals of fostering participatory, flexible learning environments tailored to students' unique needs

Abstract

One solution is to use bioplastics, which can replace synthetic plastics that are difficult to decompose. Starch is one of the materials used in the manufacture of bioplastics because it is naturally degradable. However, bioplastics made from starch tend to be brittle and easily damaged, so additional materials are needed to overcome this problem. Polyvinyl alcohol (PVA) is one of the materials used in the manufacture of bioplastics because it has properties that can be degraded naturally, is non-toxic, and is able to form good quality plastic films. This study aims to examine the effect of PVA concentration and stirring time on the mechanical properties of biodegradable plastic derived from kepok banana peels. This study used a completely randomized design with three variations of PVA concentration (3%, 4%, and 5%) and three variations of stirring time (25 minutes, 35 minutes, and 45 minutes). The results showed that at a PVA concentration of 5% with a stirring time of 45 minutes, bioplastics showed the best quality with a tensile strength value of 2.25 MPa, the best elongation at break was 416%, and the best elasticity was 0.541. In biodegradation, all samples were completely degraded within 7 days. It can be included that the addition of PVA concentration and the length of stirring effecth the mechanical properties of bioplastics but not on the biodegradation test.
