The result of this paper is application can give the decision of athletes who deserve to enter the match team. To facilitate managers and coaches in screening the best athletes. The validation test results obtained 85% compatibility between the selection results in the application and manual calculations
Peran Teknologi Untuk Revitalisasi Bandara Dan Transportasi Udara
No full textSebagian Bandara di Indonesia dibangun untuk kepentingan Pertahanan dan Keamanan. Bandara tersebut dibangun dengan sistem pelapisan berorientasi lapis permukaan (bukan lapis pondasi/base). Saat bandara di design, traffic-nya sangat berbeda dengan traffic pada saat digunakan dari sisi ukuran maupun frekuensi. Sebagian besar bandara di Indonesia dibangun secara bertahap dengab segmentasi perkerasan yang berbeda. Sebagian dibangun diatas tanah lunak, dengan kapasitas daya dukung yang sangat rendah. Sebagai contoh APT Pranoto Samarinda, H. Asam Sampit, Juanda Surabaya, dll. Sebagian dibangun di pegunungan, dengan luas bidang/medan datar (flat) yang sangat terbatas, contoh wilayah pedalaman papua). Bandara di Indensia yang telah dibangun juga dapat mengalamai kerusakan. Secara Umum ada 5 Tipe kerusakan :retak (Cracking), kerusakan pada sambungan (joint seal damage), kerontokan (disintegration), perubahan permukaan konstruksi (distortion), hilangnya kekesatan permukaan konstruksi (loss of skid resistance). Bandara yang mengalami kerusakan dapat mengganggu operasi penerbangan: delay, cancel, diverted, RTB. Kerusakan yang sering terjadi adalah: delamination, depression, dan pothole. Kerusakan tersebut dapat menimbulkan Foreign Object Damage (FOD) yang sangat membahayakan pesawat karena adanya benda asing yang dapat merusak body dan mesin pesawat. Penyebab kerusakan struktur perkerasan movement area (runway, taxiway dan apron) ada 4 faktor, yaitu : air yang meresap melalui permukaan perkerasan yang retak, misal air hujan. air yang berasal dari bawah perkerasan dan membasahi subgrade maupun subbase, misal air tanah, air yang berasal dari kawasan di sekitar bandara dan dapat menggenangi perkerasan, overload atau beban lebih pavement bearing capacity atau max allowable gross weight dari perkerasan lebih rendah dari pada bobot pesawat yang dilayani (RTOW atau MTOW)

The Analysis of Implementing Safety Management System (SMS) to Improve The Flight Safety
No full textFlight safety can be created only by good cooperation from all stakeholders in aviation. In other words, each flight stakeholder has the responsibility and contribution to the flight safety. This condition shows the importance of analyzing the implementation of Safety Management System (SMS) in the aviation industry, because it is a part of the State Safety Program (SSP) in accordance with ICAO standard. The research method is presented descriptively related to the aviation safety regulations with the current conditions of implementing flight safety. The results showed the implementation of the Safety Management System (SMS) by each flight stakeholder was running, but the "Flight Safety Promotion" activity had not been able to run properly, because there were no periodic reports issued by regulators on the Aviation Safety Program. Another thing is the violation of the implementation of Safety Management System (SMS) has not been through the "Aviation Professional Assembly", so that the personnelwho committedthe violations will get objective punishment
