Abstract

Perlakuan permukaan shot peening paling banyak diaplikasikan untuk meningkatkan ketahanan fatik dan korosi pada konstruksi pesawat terbang. Penelitian ini bertujuan untuk mempelajari pengaruh shot peening mesin otomatis terhadap laju perambatan retak fatik pada material Al 7050-T7651 serta membandingkannya dengan shot peening mesin manual.Spesimen dibentuk sesuai dengan standar ASTM E647, diidentifikasi dengan nama base metal shot peened– automatic machine (BMSPA). Proses perlakuan shot peening dilakukan di area surface treatment PT. Dirgantara Indonesia menggunakan mesin otomatis. Selanjutnya pengujian perambatan retak fatik dilakukan dengan mesin Servopulser di Lab. Bahan Teknik Jurusan Teknik Mesin UGM, dengan beban sekitar 11% dari tegangan tarik maksimum (spesimen standar ASTM E8M) yang dihubungkan dengan analisis beban kombinasi, dengan stress ratio R=0,1. Data hasil uji tersebut diolah menggunakan metode incremental polynomial untuk mendapatkan hubungan da/dN - ΔK. Hasil uji perambatan retak fatik menghasilkan angka konstanta Paris A=1,874×10-8dan n=1,06 jika dibandingkan hasil penelitian sebelumnya untuk spesimen AR as received material-tanpa perlakuan dengan A=1,288×10-9dan n=2,02; dan BMSP base metal shot peened-manual machine  dengan A=1,286×10-9 dan n=2,01. Semakin rendah nilai konstanta Paris, menunjukkan semakin rendahnya laju perambatan retak fatik. Sehingga perlakuan shot peening dengan mesin otomatis lebih mampu menurunkan laju perambatan retak fatik daripada mesin manual atau tanpa perlakuan.

Abstract

Nature has been a great inspiration for engineering design. Flying insect, in specific, has been studied and being an inspiration in the development of flapping-wing micro aerial vehicle (FW-MAV). Each species of flying insect has its own wing kinematics, but most all of them generate the aerodynamic force with the same of three mechanism: delayed stall, rotational circulation and wake capture[1]. In this research, we conduct a parametric study on the FW-MAV with different wing shapes. There are two designs of the FW-MAV in this study, which have flapping angle of 80 and 120 deg. The three different shapes of wings are mimics from: desert locust, Monarch butterfly and rhinoceros beetle. The wings then attached to the FW-MAV and operated with voltage input of 1.5V. The force generated by the FW-MAV and the electrical current measured in a swing test, while recorded in 240 fps using action camera. From the test, we get the flapping frequency, generated horizontal force and power consumption. From this research we have several data that can be used for the further development of the FW-MAV.

Abstract

Composite is a material composed of 2 materials, namely matrix and filler. Natural fibers, especially bamboo fibers and iron sand that are waste in Indonesia, have the potential to be developed as engineering materials for composite materials reinforced with natural materials. Therefore, the researcher used bamboo fiber and iron sand as a filler and epoxy resin as a matrix. The method used in this research is experimental. Impact test aims to determine the mechanical properties of the composite to be tested. In the manufacture of composite specimens, researchers used the hand lay-up method in accordance with the ASTM D 6110-10 standard. Meanwhile, to see the physical properties, researchers used macro photos to see the difference in composite fractures after impact testing. This study aims to determine the impact strength of horizontal bamboo fiber composites and iron sand with an epoxy matrix. The composite was made with fraction 1 (50% epoxy matrix and 50% horizontal bamboo fiber), fraction 2 (50% epoxy matrix and 50% iron sand), fraction 3 (50% epoxy matrix, 20% horizontal bamboo fiber and 30% iron sand ). The results of the charpy impact test showed that the impact strength of the composite fraction 1 was 50 KJ/m². for the composite test fraction 2 has an impact strength is 23 KJ/m². Meanwhile, fraction 3 produces an impact strength is 30 KJ/m². It can be seen from the results of the macro photo that the specimens of fractions 1 and 3 have fiber pull-outs, while for fraction 2 it can be seen that the sand grains absorb resin well.

Abstract

ILS Panatagama Islamic Boarding School does not yet have sufficient supporting facilities to facilitate learning activities, especially learning in the field of science. Learning facilities are needed to provide insight and prepare students before entering a higher level of education and getting involved with life in the midst of society.The service activity aims to help the application of science learning, especially Physics lessons on RC (Remote Control) Aeromodelling Airplanes at the Taruna Panatagama Putri ILS Islamic Boarding School. The approach method offered to solve partner problems is through observation and discussion with school management, followed by lectures, training workshops and assistance in the use of RC Aeromodelling, especially drones. Through this activity, Santri gain insight and operational strengthening of the use of drones for various activities
