Background : The Knee joint is a hinge joint with a change formed by the two condyls of the femur that are jointed with the superior surface of the tibial tube. Radiographic examination of the knee joint on AP weight bearing and lateral weight bearing projections is a good projection in revealing joint gaps in the knee joint. The constraints on this examination are when patients who have little difficulty standing on one leg when doing lateral projection of weight bearing. So that a knee joint examination tool is needed in the case of osteoarthrithis.Methods : The purpose of this study was to describe the design, study the function tests and performance tests of knee joint hearing aids in the case of osteoarthrithis.This research is a type of experimental research with the design of a one shoot case study. Data collection is obtained by a check list of results of functional tests and performance test tools. The data obtained was assessed by Guttman's scale and conclusions and suggestions were drawn.This study produced a design in the form of a knee joint examination tool. The tool is made of stainless steel pipes, on a pedestal made of wooden boards, foam and cloth. Based on the calculation of the check list using the Guttman scale.Result: The function test results were 100% and the performance test results were 96%. Until the knee joint examination tool in the case of osteoarthrithis is said to be feasible to use.Conclusion : This knee joint examination aid has a number of parts, a pedestal made of wood sheets, adjustable footrests, and a patient's padded arms. The auxiliary framework uses a 3 cm diameter stainless steel pipe with a thickness of 1 mm. Based on the functional tests in the Radiology Installation of Prof. Dr. Margono Soekarjo Purwokerto obtained results 100% for knee joint examination in osteoarthritis cases with AP weight bearing projections and lateral weight bearing. Based on performance tests which involved 5 respondents who were radiographers were said to be very appropriate with a percentage of 96% with an excess of ease in operation, reducing the movement of patients, and helping the radiographers to produce informative radiographs.

Nasabah adalah konsumen pengguna jasa perbankan yang memiliki hak mendapatkan perlindungan hukum dalam melakukan transaksi. Perkembangan teknologi mendorong nasabah untuk melakukan transaksi secara non tunai (cashless). Produk-produk uang elektronik memberikan solusi kepada konsumen berupa kemudahan bertransaksi. Salah satu produk uang elektronik yang beredar di masyarakat  adalah Brizzi yng diterbitkan oleh PT Bank Rakyat Indonesia (Persero) Tbk. Seiring meningkatnya penggunaan Brizzi di masyarakat, permasalahan terkait penggunaannya pun seringkali dialami oleh pemegang kartu. Permasalahan tersebut menjadi salah satu resiko yang dihadapi pemegang kartu.     Dalam proses penyelesaian masalah inilah seringkali hak nasabah dalam perlindungan konsumen dikesampingkan. Dari latar belakang tersebut, maka dalam penelitian ini dirumuskan permasalahan sebagai berikut : (1). Bagaimana perlindungan hukum bagi konsumen pengguna kartu Brizzi menurut Undang-Undang? (2) Apa saja resiko yang ditanggung oleh pengguna kartu Brizzi dalam bertransaksi? (3) Bagaimana penyelesaian masalah apabila terjadi hal yang merugikan konsumen pengguna kartu Brizzi. Metode pendekatan yang digunakan dalam penelitian ini adalah yuridis normatif. Dalam pendekatan yuridis, hukum dilihat sebagai norma sehingga pendekatan ini mengacu pada peraturan perundang-undangan yang berlaku. Pendekatan normatif digunakan untuk menganalisis hukum sebagai suatu perangkat aturan perundangan yang bersifat normatif. Berdasarkan penelitian yang dilakukan, resiko yang dihadapi pengguna kartu antara lain gagal top up tapi saldo terdebet, jaringan offline, Brizzi rusak,hilang, pasif, dan permasalahan biaya. Permasalahan tersebut dapat diselesaikan oleh Bank BRI sebagai bank penerbit melalui layanan Call BRI 14017, Customer Service di unit kerja, maupun melalui media sosial BRI. Maksimal penyelesaian adalah 14 (empat belas) hari kerja dihitung dari diterimanya komplain oleh Bank BRI. Perlindungan hukum bagi nasabah terkait transaksi pembayaran non tunai khususnya kartu BRIZZI menurut Peraturan Otoritas Jasa Keuangan No.1/POJK.07/2013 tentang Perlindungan Konsumen Sektor Jasa Keuangan adalah penerapan prinsip transparansi, perlakuan yang adil, keandalan, kerahasiaan dan keamanan informasi konsumen, serta penanganan pengaduan dan penyelesaian sengketa konsumen secara sederhana, cepat dan biaya terjangkau. Bank BRI perlu meningkatkan kualitas layanan dan meningkatkan keamanan bagi nasabah pemegang kartu Brizzi yang berkebutuhan khusus.

The sagital T2* W MERGE sequence is a sequence in Magnetic Resonance Imaging (MRI) examination of the knee joint in the radiology department of Panti Rapih Hospital Yogyakarta. The value of Flip Angle (FA) on the T2 * W MERGE sequence will affect to anatomical information. The right FA can produce good image contrast of fluid and tissue. This study aims to find out the relationship between FA variations toward anatomical information and to determine the the optimum FA. Ten patients with Anterior Cruciate Ligament (ACL) Tear were scaned by 1.5 Tesla MRI using Sagittal T2 * W MERGE with five flip angle variations: 150, 200, 250, 300, and 350. The anatomical informations were assesed by two qualified radiologists in ACL Tear, Posterior Cruciate Ligament (PCL), Quadriceps Tendon, Joint Effusion, and Hoffa Fat Pad. Data were analyzed by Cross Tabulation, Spearman Rank test and Freadman test. Result showed that there was a significant correlation (p-value < 0,05) between flip angle value to anatomical information (correlation value was -0.55), increasing the FA will reduce the clarity of the anatomical image. Based on Freadman test results, the highest mean rank of image information was 3.89 obtained by FA 200.

Background: Axiolateral projection of mastoid examination with Schuller method using angle range of 25°-30° caudad according to Bontrager (2010). The difference thickness of the human’s head will cause range of angles of axiolateral projection of mastoid examination using Schuller projection. The inappropriate angle will affect the different anatomical information. Axiolateral projection of mastoid examination using Schuller projection in Radiology Installation of dr. Soetomo Hospital used an angle that is 25° for all patients with different thickness of the head. This study aims to determine the differences in anatomical image clarity on radiographic image of axiolateral projection of mastoid examination using Schuller method with an angle that is 25° with variations of head thickness between 12 to 14.5 cm.Methods: This research was a quantitative research with an experimental approach. Subjects of this reearch were 10 respondents. Data analyzed statistically by Kruskal Wallis test and Mann Whitney test.Results: The results showed that there was difference in anatomical image of axiolateral projection of mastoid examination with Schuller method with 25° angle. Result of statistical test to get optimal radiographic image of mastoid using Schuller method showed the significant value, which was 0,000. Differences in anatomical image was also shown on the assessment results from 10 respondents which most of respondents assess anatomical features on a 14.5 cm head thickness was very good.Conclusion: There were differences anotomical information of mastoid radiograph using schuller method with thickness variaton of head. Head thickness of 14.5 cm can show anatomical image of the mastoid air cells, bony labirinth, condyle mandible, temporomandibular joint (TMJ), Aacousticus the external meatus (MAE) and tegmen tympani. The CR angle should be considered based on head thickness.
