Selain bertindak sebagai pemilik (owner), Anggota koperasi sekaligus sebagai pengguna (user) yang partisipasinya sangat berpengaruh terhadap keberhasilan koperasi. Tujuan dari penelitian ini adalah untuk mengetahui faktor-faktor yang mempengaruhi partisipasi anggota Koperasi Sejahtera Bersama Syariah (SBS), untuk mengetahui pengaruh tingkat partisipasi anggota terhadap keberhasilan koperasi. Metode penelitian ini menggunakan pendekatan kualitatif deskriptif, dengan menggunakan data primer dan data sekunder, data primer diperoleh dari hasil wawancara, sedangkan data sekunder diambil dari buku, jurnal, artikel, dan media lainnya. Hasil dari penelitian ini diketahui bahwa ada tiga faktor yang mempengaruhi partisipasi anggota yaitu, pemahaman anggota terhadap koperasi, manfaat yang diterima anggota dari koperasi, dan program koperasi terkait peningkatan mutu pelayanan. Tingkat partisipasi anggota berpengaruh positif terhadap keberhasilan koperasi.

Background & Objectives: Unspecified lower abdominal pain might confuse clinicians in diagnosing pediatric appendicitis. Ultrasonography, as an initial affordable tool, has been learned its role in reducing unnecessary appendectomy. This study aimed to determine the accuracy of ultrasonography in pediatric acute appendicitis and its correlation to intraoperative findings, confirmed by histopathology results. The result would verify other study experience. Methods : The study was a diagnostic study which retrospectively review the children who underwent an ultrasound study for suspected appendicitis in pediatric surgery division of Haji Adam Malik Hospital and Universitas Sumatera Utara Hospital, Medan, North Sumatera between January 2014 until March 2019. We determined the accuracy along with sensitivity and specificity results of Ultrasonography (USG) using calculated formula. The comparation between ultrasonography results and intraoperative findings was analyzed using Chi Square test or its alternative. Results : Among the 32 patients, male and female were almost equal in 1:1 ratio, with mean age of 14.06 (±3.98) years old. Twenty-six patients were positively diagnosed as appendicitis using ultrasonography. Only two patients have no appendicitis based on intraoperative findings, confirmed by histopathology results. There is a statistically significant difference between ultrasonography findings and histopathology results (p=0,03). We obtained the accuracy of ultrasonography in predicting appendicitis was 87.5%, with 86.7% sensitivity and 100% specificity. Conclusion : Our results compare favorably with alternative studies, however indicate the potential for improvement in accuracy of image, with a future study incorporating new ways of categorizing ultrasound findings presently being undertaken.

Introduction: Appendicitis is the most common cause of surgery in children in the emergency unit. Diagnosis of appendicitis in children is difficult, the diagnosis of appendicitis is based on clinical symptoms, physical examination, laboratory and investigation, namely radiological imaging, To help in establishing a diagnosis of acute appendicitis in children, there is a scoring system that has been proposed and until now the one used is the Pediatric Appendicitis Score (PAS), Ultrasound is the most commonly used diagnostic procedure because it does not cause pain in its use and the results can be known directly. Method:This study is a prospective analytical study with cross sectional design to see the relationship between the results of the Pediatric Appendicitis Score (PAS) with the results of Ultrasound (USG) preoperative appendix in children. The target population is pediatric patients with complaints of abdominal pain and clinically diagnosed appendicitis. Affordable population was pediatric patients with complaints of abdominal pain and appendicitis diagnosed with treatment at General Hospital Haji. Adam Malik and USU Hospital in Medan.Data will be analyzed descriptively to see the frequency distribution of research subjects based on the characteristics and types of appendicitis using the Chi square test, the results are significant with a significance value of <0.05. Result:Majority of the study samples were 19 women (57.6%) with a median age of 13 years. The results of the PAS calculation showed that 63.5% entered into the simple category while the USG results of 84.8% stated suggestive of appendicitis. There is not significant relationship between PAS with ultrasound examination results with p> 0.05, p = 0.076. Conclusion: We have shown patients of appendicitis by using Ultrasonography and compared it with PAS the final result, there is no significant value, we conclude that USG and PAS could be the main tools for diagnostic but there is no relatonship between USG and PAS.
