Abstract

Sistem pemanas yang dimiliki Program Studi Teknik Pesawat Udara Sekolah Tinggi Penerbangan Indonesia menghasilkan panas yang tidak merata sehingga akan berpengaruh pada penyatuan fiber dan matriks pada panel komposit tersebut, tentunya akan lebih baik jika terdapat sistem pemanas yang dapat menghasilkan panas secara menyeluruh dan curing time dari proses pengerasan itu dapat terpenuhi. Tahapan perancangan dimulai dengan perumusan masalah, pengumpulan data, pengolahan data, perancangan dan pemilihan sistem pengatur panas, perakitan komponen, uji coba rancangan, interpretasi dan kesimpulan. Proses perancangan elemen pemanas dimulai dengan menentukan temperatur maksimal proses pengerasan panel komposit yaitu 100 C, penghitungan lama proses pengerasan yaitu 101 menit dan pemilihan elemen pemanas, yaitu 2 buah elemen pemanas tubular dengan panjang 100 cm dan diameter 8 mm. Dan proses pemilihan sistem pengatur panas dimulai dengan pemilihan komponen thermocouple, pengatur temperatur, sakelar, lampu indikator, kabel, circuit breaker, fuse dan yang terakhir adalah contactor. Dari perancangan ini diharapkan mampu mengatasi permasalahan pada alat pemanas sebelumnya.

Abstract

Composite Curing process is need vacuum system to remove air bubble and heating system to decrease time of curing proses. Vacuum and heating system at composite panel curing practical at program studi teknik pesawat udara conducted separately, so need composite panel curing equipment that have integrated Vacuum and heating system. Vacuum system in this composite panel curing equipment is designed by design step including vacuum pump selection, hose selection, vacuum system design. Discussion results rate of flow of 37 L/min. With the fluid velocity of 20m/s. vacuum pump pressure of 14.5 inHg. Components required for vacuum system is a vacuum pump, vacuum regulator, vacuum gauge, nipple, vacuum bagging port, flexible Teflon hose.

Abstract

The final objective of this design is to optimize the curing process in the manufacture and repair of composite panel for interchanges curing process using a heat gun, because by using a heat gun the curing process is not optimal. The design focuses on making the furnace only on the other parts are designed on other designs. The goal that must be achieved is to make optimal heat distribution in the furnace. Tests carried out to get all the components that did not change the shape during the composite curing process that occurred, components that did not change from the shape received, and the length of expansion of the work-piece within the specified range. Will there be one criterion which has not yet been agreed upon, the top surface of the furnace wall is 41.7 ℃ causes the surface of the upper wall to pass through a predetermined range affecting the buoyancy force which causes the air density to decrease and hot air as it moves upward. This is what causes heat transfer to the surface which is higher than the other sides

Abstract

B.Indonesia Dalam proses pelepasan dan pemasangan tail boom di Direktorat Polisi Udara khususnya di out base station ditahan oleh beberapa orang. Proses tersebut dapat berakibat beberapa baut rusak. Selanjutnya tail boom diletakkan pada sebuah rack. Untuk itu penulis mencoba memberikan solusi memodifikasi tail boom rack yang bertujuan untuk menggantikan sling dan crane sebagai pengangkat. Dalam rancangan modifikasi dibagi menjadi empat pembahasan. Pertama, merancang rangka. Selanjutnya membandingkan dengan tegangan yang diizinkan material. Kedua, merancang ulir penggerak dengan menggunakan teori ulir daya. Setelah di dapat panjang ulir maka dapat ditentukan seberapa tinggi alat ini mampu mengangkat tail boom. Ketiga, merancang pengatur sudut kemiringan tail boom. Keempat, menentukan bearing. Dari pembahasan di dapat tegangan pada rangka atas adalah 0,58kg/mm2 dan pada lengan penggerak adalah 19,466 kg/mm2, alat mampu mengangkat sampai 146 cm, sudut yang didapat mencapai 3,03° adapun bearing dengan digunakan adalah roller bearing tipe ball bearing dengan nomor 6208. B.English In the process of the removal and installation tail boom especially in out base station hangar of Directorat of Polisi Udara is lifted by some people. That process can affect some the bolts has broken. Because of that, the authors try to provide a solution by modifying tail boom rack that aims to replace the sling and crane those are not in the out base station as carrying out the. In modification there are four discussion. The first, design the framework modifications and comparing the stress that allowed by material. The second, design thread driver. After the length of power thread is known it can then be determined how high the tool is capable of lifting tail boom. The third, design the angle setting. From there it can be determined the tilt of angle of tail boom. The fourth, decisive the bearing. From the discussion it get the stress that happen on the upper frame is 0,58kg/mm2 and the drive arm is 19.466 kg/mm2, the tool is capable of lifting up to 146 cm, which can reach the angle of 3.03 °, use roller bearing type ball bearing with the number 6208.

Abstract

This research was conducted based on the results of the data record condition of safety in maintenance unit issued by the safety and quality department of PT. Avia Teknik Dirgantara who explained that every year starting from 2017-2021 there were several incidents that caused minor injuries to the workers in the company. There are two research variables that will be analyzed related to their relationship. The data analysis technique used in this quantitative analysis is parametric statistics in which there are simple correlation techniques and simple linear regression. The objectives and targets of this study are to determine the correlation and effect between the work environment and safety risk management, and the relationship between the two can be explained through the regression equation. The results showed a positive and significant relationship between the two variables. Obtained a correlation coefficient of 0.876 which indicates a very strong level of relationship between work environment variables and safety risk management. The work environment contributes 76.7% to safety risk management. The effect of the work environment on safety risk management is obtained by the regression equation Y = 1.389 + 0.487X.
