Abstract

B.Indonesia Terowongan angin model terbuka laboratorium fluida Prodi Teknik Pesawat Udara PPI Curug digunakan untuk pembelajaran pola aliran udara berbagai model airfoil. Studi awal menunjukkan kecepatan udara di ruang uji memiliki rentang 14,493 fps – 41,838 fps, laminar sehingga memenuhi syarat diperlengkapi alat baca Lift dan Drag. Metode timbangan overhead digunakan dan lendutan pegas ulir baja tahan karat berdiameter 0,8 mm untuk Lift 0 – 2,5 lbs dan 0,2 mm untuk Drag 0 – 0,4 lbs. Setiap mm lendutan pegas membaca 0,0122 lbs Lift dengan akurasi 0,02 mm sama dengan 0,000244 lbs, dan membaca 0,0022 lbs Drag dengan akurasi pada vernier 0,02 mm. Beban maksimum pada pegas dihitung berdasarkan gaya terbesar pada model uji NACA 0012, NACA 2424 dan NACA 4412. Hasil penelitian memperlihatkan alat baca dapat mengukur rentang Lift negatif terbesar terjadi dengan model NACA 0012 sebesar 2,2642 lbs dan Lift positif terbesar terjadi pada NACA 4412 sebesar 1,839 lbs. dengan lendutan maksimum pegas 199,47 mm. Beban tarik pegas terbesar mengukur nilai Drag terjadi pada model NACA 4412 sebesar 0,0393 Lbs dengan lendutan maksimum pegas 18 mm. B.English Open type wind tunnel within the fluid laboratory of Prodi Teknik Pesawat Udara PPI Curug was utilized solely for training purpose to examine the variation of airflow over many kinds of airfoil model. Preliminary research showed the airspeed in the test chamber exhibits the laminar flow with the velocity range of 14.493 – 41.838 fps, and was technically met with the requirements to be equipped with Lift and Drag balance. The design adopted the simple overhead troly type balance with stainless steel coil spring as the main components with 0.8 mm diameter to measure 0 – 2.5 lbs Lift and a 0.2 mm diameter to measure 0 – 0.4 lbs Drag. With the 0.02 mm accuracy. For each mm spring deflection results in reading capability of 0.0122 lbs Lift equal to 0.000244 lbs calculated Lift, and 0.0022 lbs Drag equal to 0.000009 lbs calculated Drag. Maximum load is analyzed referred to the highest force possessed by NACA 0012, 2424 and 2412 airfoil model. Research study shows the balance is capable to measure the range of aerodynamic force of 2.2642 lbs highest negative Lift with NACA 0012 and 1.839 lbs highest positive Lift with NACA 4412 producing maximum spring deflection of 199.47 mm. Maximum spring tension of Drag measurement is 0.0393 lbs force possessed by NACA 4412 with 18 mm deflection.

Abstract

B.indonesia Ruang Makan Taruna merupakan salah satu fasilitas yang terdapat di Polteknik Penerbangan Indonesia Curug. Di Asrama Curug I , ruang makan yang digunakan sejumlah dua buah. Ruang makan taruna 1 digunakan oleh taruna senior dan ruang makan taruna 2 digunakan oleh taruna junior. Ruang makan taruna 1 memiliki kapasitas daya tampung hingga 302 taruna dalam waktu sekali makan, sedangkan ruang makan taruna 2 memiliki daya tampung sebanyak 386. Pada kedua ruang makan tersebut belum terpasang alat pengkondisian udara. Pengkondisian udara merupakan usaha untuk memberikan kenyamanan dan kesegaran bagi si pengguna ruangan. Pengkondisi udara diperlukan untuk menyerap kalor yang dihasilkan baik dari dalam ruangan maupun dari luar ruangan untuk menciptakan kenyamanan pada ruang tersebut. Metode yang digunakan untuk melakukan perhitungan beban adalah Metode Cooling Load Temperature Different (CLTD). Metode CLTD adalah prosedur manual untuk mengukur beban pendinginan melalui perolehan panas radiasi, konduksi matahari, beban internal, dan beban eksternal. B.English The Cadets’ Dining Room is one of the facilities at the Indonesia Aviation Polytechnics-Curug. There are two dining rooms at Curug I dormitory. The cadets’ dining room 1 is used by senior cadets and the cadet's dining room 2 is used by junior cadets. The cadet dining room 1 has a capacity of up to 302 cadets, while the cadet 2 dining room has a capacity of 386 cadets. In both dining rooms, air conditioning devices are not yet installed. Air conditioning is an attempt to provide comfort and freshness to the user of the room. Air conditioners are needed to absorb heat generated both indoors and from outside the room to create comfort in the space. The method used to perform load calculations is the Cooling Load Temperature Difference (CLTD). CLTD method is a manual procedure to measure cooling loads through the acquisition of radiation heat, solar conduction, internal loads, and external loads.

Abstract

B.English Saat ini dunia pendidikan sedang menghadapi tantangan yang berat untuk menyiapkan Sumber Daya Manusia yang berkualitas dan mampu bersaing di era global. Salah satu faktor penunjang kegiatan belajar mengajar adalah kondisi laboratorium yang siap pakai dan terawat. Kondisi siap pakai dan terawat tersebut bisa terpenuhi apabila dilakukan perawatan yang sesuai dengan prosedur pemeliharaan oleh teknisi. Teknisi harus didukung oleh data penggunaaan dan perawatan yang akurat untuk melakukan perawatan secara maksimal.Selama ini data penggunaan laboratorim dicatat di logbook yang berada di masing-masing laboratorium dan data perawatan tidak tercatat dengan rapi , taruna maupun dosen tidak mengisi atau lupa tidak mengisi logbook, sehingga teknisi tidak dapat mendapatkan data penggunaan laboratorium dengan akurat. Dengan tidak akuratnya pencatatan penggunaan dan perawatan laboratorium maka akan menghambat tugas teknisi untuk melakukan perawatan laboratorium. Berdasarkan hal tersebut di atas, maka penulis membuat sebuah alat pencatat penggunaan dan perawatan laboratorium berbasis PC dan mikrokontroler Currently the education world is facing a serious challenge to prepare qualified human resources and competitive in the global era. One factor supporting teaching and learning activities is a ready-made laboratory conditions and maintained. Readymade and well-maintained condition can be met if the treatment is performed in accordance with maintenance procedures by technicians. Technicians must be supported by the use of data and accurate care to perform optimally care .So far, the data usage is recorded in the logbook laboratory are located in each laboratory and treatment data were not recorded with neat , cadets and lecturers forget to fill or not fill the logbook , so that technicians can not get the data with accurate laboratory use . With the use of inaccurate record keeping and laboratory maintenance tasks it will hinder the lab technician to perform maintenance. Based on the above , the authors make a recording device use and care of laboratory-based PC and microcontroller.

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.
