Non-destructive adalah teknik non-invasif untuk menentukan integritas bahan, struktur objek tanpa menghancurkan benda uji. Antena microstrip adalah suatu konduktor metal yang menempel diatas groundplanendiantaranya terdapat bahan dielektrik.Perancangan antena mikrostrip pada penelitian ini menggunakan CST StudioSuite2019. 1) Menghasilkan rancangan pada CST suite studio antena mikrostrip dengan karakteristik yang telah ditentukan.2) Dapat memahami perancangan antena mikrostrip dengan menggunakan CST suite studio. 3) Mengaplikasikan antena mikrostrip yang dirancanag sebagai sensor Non-destuctive pada alat uji pada kadar larutan gula. 4)dapat merancang antena mikrostrip menggunakan bahan FR-4 (lossy).perancangan antena ada berberapa harus dilakukan,yaitu menentukan parameter antena,menentukan bahan substrate,patch,ground plane dan melakukan perhitungan terhadap dimensi patch,substrate dan ground.Pengujian Antena A&B menggunakan VNA. Hasil pengukuran S11 Antena A, semakin pekat kadar gula dalam larutan, maka S11 meningkat, sedangkan Phase tidak teratur. Hasil pengukuran S11 Antena B, semakin pekat kadar gula dalam larutan, nilai S11 tidak teratur, sedangkan Phase konstan naik. Hasil pengujian antena A untuk kadar larutan gula menggunakan VNA menunjukan semakin meningkat kadar gula dalam air, maka nilai S11 antena konstan naik sedangkan pada phase menjadi tidak teratur. Hasil pengujian antena B untuk kadar larutan gula menggunakan VNA, meningkatnya kadar gula dalam air maka nilai S11 tidak teratur sedangkan pada phase konstan naik.
<p><strong><em>Abstract</em></strong></p><p><em>The objectives of the study were: (1) to describe the steps in implementing Project Based Learning (PjBL) model in improving mathematics learning outcomes about distance, time, and speed, (2) to increase mathematics learning outcomes about distance, time and speed by applying Project Based Learning (PjBL), and (3) to describe the constraints and solutions in implementing Project Based Learning (PjBL) model in improving mathematics learning outcomes about distance, time, and speed. The research was collaborative classroom action research conducted in three cycles. The subjects were students and teacher of fifth grade SDN Kledungkradenan. The data were qualitative and quantitative data. Data collection techniques used observation, interviews, and tests. The data validity used triangulation of techniques and triangulation of sources. Quantitative and qualitative data analysis included data reduction, presentation, and conclusion. The results showed that: (1) the steps in the implementation of Project Based Learning (PjBL) model were: (a) presenting problems, (b) preparing project plans, (c) preparing project activity schedules, (d) monitoring project implementation, (e) presenting project results, (f) evaluating project results; (2) the application of Project Based Learning (PjBL) model improved mathematics learning outcomes about distance, time and speed; (3) the constrains were: some students were passive in project activities and did not get enough tools needed in making projects while the solutions were: the teacher monitored the learning and discussion activities, the teacher encouraged the students to participate actively in project activities, and the teacher and the students prepared the tools and materials needed in learning</em></p>
Background: A goiter is an enlargement of the thyroid gland caused by abnormalities of the thyroid gland in the form of malfunctioning or disorders of the structure of the gland and its morphology. According to WHO, the incidence of goiter is still quite high with iodine deficiency as the main cause.
Objective: This study aims to determine the description of ultrasound examinations in goiter patients in Department of Radiology DR. M. Djamil January-December 2019 period.
Method: This research was a retrospective descriptive study using cross sectional method using secondary data on 123 patients with thyroid goiter who meet the inclusion criteria in RSUP DR. M. Djamil Padang period January 2019-December 2019. The sampling method used a total sampling technique. Result: The results showed that 112 patients with thyroid goiter disorders met the inclusion criteria. The most clinical diagnosis results were goiter nodusa as many as 61 people (54.5%). The highest incidence was in the age range 41-50 years with 35 people (31.3%). The most gender was 88 women (78.6%). The results of ultrasonography in most goiter patients were diffuse in 43 people (38%).Conclusion: The conclusion of this study, it was found that the most age group of patients suffering from goitre were 41-50 years old, the majority of goiters occurred in the female compared to the male and the results of the most thyroid ultrasound images were diffuse goiter
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.
