AKSESBILITAS KAMPUS RAMAH DIFABEL

Sering kali kita mendengar istilah ramah difabel dilekatkan pada berbagai sarana prasarana maupun layanan publik. Sehingga sering kali pula kita jumpai istilah puskesmas ramah difabel, sekolah atau kampus ramah difabel, kantor pemerintah ramah difabel, dan sebagainya. Salah satu ciri kampus ramah difabel adalah terbukanya dengan luas akses belajar dengan baik, misalnya, tersedianya jalur pedestrian dengan guiding block, ramp (jalan miring) untuk masuk ke sebuah gedung, adanya tangga dengan pegangan tangan (hand-rail), lift dengan tombol huruf braille, dan toilet khusus difabel di setiap gedung. Syarat-syarat mengenai sarana prasarana ramah difabel secara detail telah diatur pada Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat (PermenPUPR) Republik Indonesia No 14 Tahun 2017. Untuk membangun aksesbilitas yang prioritas bagi mahasiswa difabel UMY akan dilaksanakan beberapa kegiatan seperti survei untuk pendataan mahasiswa difabel Universitas Muhammadiyah Yogyakarta (UMY), diikuti dengan seminar, dan dilanjutkan dengan evaluasi dan sarana prasarana untuk aksesbilitas mahasiswa difabel UMY melalui survei lapangan. Melalui survei tersebut, Gedung kembar AR Fachruddin UMY memang sudah mempunyai akses jalan miring, tangga dengan hand-rail, dan lift dengan tombol huruf braille, namun belum memiliki toilet khusus difabel yang sesuai standar untuk mereka yang mempunyai kebutuhan khusus sesuai PermenPUPR No 14 Tahun 2017 tersebut. Survei juga dilakukan pad Gedung Admisi, Gedung Siti Walida F3, serta jalur pedestrian antara Gedung AR Fachruddin, Gedung Admisi, dan Gedung Siti Walida.

Block ramps for stream power attenuation in gravel-bed streams: a review

Application of block ramp technique in steep gradient streams for energy dissipation as well as to maintain river stability finds increasing favor amongst researchers and practitioners in river engineering. This paper dwells on a comprehensive state-of-the-art review of flow resistance, energy dissipation,flow characteristics, stability, and drag force on block ramp by various investigators in the past. The forms and equations for each type are thoroughly discussed with the objective of finding the grey areas and gaps. While, more research is warranted further to improve the equations, essential for design analysis. Block ramps can be a promising simple technique to achieve reasonable attenuation of devastating fluvial forces unleashed in gravel-bed streams during cloud bursts.

HYDRAULIC PARAMETERS OF THE BLOCK RAMP WITH RIDGE TYPE NOTCH: THE GRAJCAREK IN SZCZAWNICA, POLISH CARPATHIANS

Aim of the study: The aim of this study is to analyze the hydrodynamic parameters in the area of one of the block ramp in the analyzed stream. Material and methods: The field research included geodetic measurements on the basis of which the longitudinal profile and cross-sections of the watercourse bed and structures were made. Numerical modelling of flood flows was also performed in the HEC-RAS program, from which hydrodynamic data were obtained. The data obtained from field measurements and numerical modelling were used to calculate the length of the energy dissipation basins of the structure and to determine the type of water movement using the Froude number. The calculations were performed for several variants. The real lengths of the energy dissipation basin were compared with the lengths of hydraulic jumps that are formed on them. Results and conclusions: The obtained results indicate that the length of the energy dissipation basin is too short because the hydraulic jumps go beyond them. As a result, a scour is formed below the structure, which in the event of further development may threaten the stability of the structure.

GRAVEL BED RIVER SCOURING ANALYSIS DOWNSTREAM OF BLOCK RAMP (EXAMPLE FROM THE PONICZANKA STREAM IN PONICE VILLAGE)

The work describes the scouring process downstream of boulder block ramps on Poniczanka Stream in Ponice village. The depth of the downstream scouring rate was calculated using empirical formulae due to different authors. The results of the calculations were verified basing on the field measurements. Finally only those formulae which results were most consistent with field observations and those with were the worst consistent with field observations are presented along a paper. Thus the aim of the study was to verify the existing formulae of the scouring depth calculation downstream of block ramp hydraulic structure on the basis of the results of field research. It was found that the empirical relationships for calculating the scouring depth in observed case are not satisfied enough, however they can be used for comparative analysis for designers.
