Corrosion control assessment for Indonesian ageing aircraft

Abstract

R-80 is a regional passenger aircraft with twin-turboprop engine designed by PT Regio Aviasi Industry. In this era, R-80 existence in Indonesian aviation market is still not perceived, while the purpose of creating R-80 is to supply local demand. Meanwhile, most of airlines in Indonesia prefer using ATR-72 as their fleet. If we look at Indonesia's airports condition, plenty airports runaways length are less than 1400 meters. R-80, need only 1,200 meters for take off and landing, is really suitable to use in Indonesia. R-80 also has a bigger fuselage than ATR-72; make it more efficient in carrying passengers. R-80 fuel capacity is less than ATR but it can carry more payload than ATR, it makes R-80 has less fuel consumption. This journal use SWOT analysis as a method to identify the internal and external factors that will affect the company's project.

Exfoliation Corrosion and Pitting Corrosion and Their Role in Fatigue Predictive Modeling: State-of-the-Art Review

“…In addition, in these aircraft, corrosion was often found in the area surrounding the cargo compartment, wing structure, and landing gear. The types of corrosion found in these aircraft were of exfoliation, galvanic, filiform, and stress corrosion, and among these exfoliation corrosion was found in most cases [42].…”

“…In both military and commercial aircraft, internal and external wing structures as well as the fuselage bilge areas and flight control surfaces are found to be most affected by corrosion in a marine and tropical environment [41]. The major causes of corrosion in aging aircraft as observed in Indonesian aging aircraft were found to be due to spillage of toilet liquid, contamination due to spillage or evaporation from the cargo compartment, and contamination due to high humidity [42]. In addition, in these aircraft, corrosion was often found in the area surrounding the cargo compartment, wing structure, and landing gear.…”

Lembar Kerja Peserta Didik (LKPD) Bermuatan Kearifan Lokal Terintegrasi TPACK untuk Siswa Kelas V Sekolah Dasar, Efektifkah?

“…Interaksi ini diharapkan dapat meningkatkan aktivitas peserta didik dalam meningkatkan hasil belajarnya. Manfaat LKPD yaitu 1) peserta didik menjadi aktif dalam kegiatan pembelajaran, 2) Peserta didik terbantu dalam mengembangkan konsep, 3) Peserta didik berlatih mengembangkan keterampilan prosesnya, 4) Menjadi pedomanguru dan peserta didik dalam kegiatan pembelajaran, 5) Peserta didik terbantu dalam menerima materi dan informasi secara sistematis tentang konsep yang dipelajari (Suyitno, 2014). Lembar kerja siswa atau lembar kerja peserta didik (LKPD) sangatlah membantu peserta didik memahami materi.…”
