Abstract

The Flight Deck or cockpit is designed to support the prosecution of its aircraft mission and these are what the Flight Deck design process needs to ensure but not limited to display design, aircraft control, automation, HCI on the Flight Deck and pilot’s view to outside namely external vision. The external vision must satisfy regulatory requirements which intended to ensure that the view is adequate for pilots to operate the aircraft safely and gives them a reasonable opportunity to see and avoid other aircraft that pose a collision threat. Concurrently during critical periods of flight, it is important that the flight crew access information in front of his view with minimal head rotation. Cockpit-Displays with critical flight information should then be located to these locations. Compromising both external and internal vision as Pilot’s visibility should be attained. Further, some OPTIONs to arrange the PFD in cockpit instrument panel give difficulty in term of its panel space, safety and comfort for the pilots. Two layout PFD’s, In-line and T-line layout, are evaluated in the new Regional Aircraft Cockpit using avionics 15.1” or 14.1” display. Due to cockpit space, the In-Line four of 15.1” display cannot fit the instrument panel and disregard; however the T-Line for 15.1” display is possible as OPTION 1. The four of 14.1” displays are possible to arrange as In-Line and T-Line layout as OPTION 2 and OPTION 3 respectively, and both may offer compliance to regulatory requirements also to both Pilot’s external and internal vision.

Abstract

To accurately detect objects, the radar antenna must have a high gain for the desired range. The antenna uses an array method to increase the gain. It has a unidirectional radiation pattern to meet the X-band radar implementation as a ship navigation tool. The X-band radar works at high frequencies. Thus, it will be more sensitive in detecting small particles, including rain particles. The use of a mitered-bends feeding network method by cutting the 90-degree curve is to maximize the power transmitted to reduce losses. This method spreads the bandwidth of the antenna. The antenna is designed and fabricated into a linear array of 8 elements, using the R04003C Rogers substrate with a microstrip line supply. This study limits up to 8 elements of radiation, followed by the addition of a method to expand the bandwidth of antennas. Considering material limitation and duration of antenna design. The final antenna dimensions are 142.40 mm × 42.8 mm. The measuring results show fc = 9.496 GHz, S11 = -32.64 dB, VSWR 1.05, bandwidth = 41.9 MHz (9.5159 GHz - 9.4740 GHz), and gain 8.8 dB as well as a linear polarized antenna with unidirectional pattern direction. The radar antenna tends to have a narrow beamwidth and high gain.

Abstract

Pemantauan kualitas udara dalam gudang elektronik sangat penting untuk menjaga kesehatan manusia dan kualitas barang elektronik. Penelitian ini bertujuan untuk memantau nilai densitas debu pada suatu ruangan khususnya pada gudang elektronik, dan mengetahui hubungan antara densitas debu, suhu, dan kelembaban. Metode yang digunakan dalam penelitian ini adalah eksperimen dan uji statistik. Dan untuk uji statistik yang digunakan menghasilkan bahwa tidak ada hubungan antara densitas debu dan suhu hal ini dibuktikan dengan nilai chi-square hitung (0,265) lebih kecil dari chi-square tabel (1,645) dan tidak ada hubungan antara densitas debu dan kelembaban hal ini dibuktikan dengan nilai chi-square hitung (0,1023) lebih kecil dari chi-square tabel (1,645). Tingkat debu pada Gudang Elektronik Depo Pelita pada tanggal 22 juli 2021 sampai dengan 30 Juli 2021 memiliki rata-rata 0,13 mg/m3 atau 130 µg/m3. Hasil penelitian ini yaitu debu tidak dapat dipengaruhi oleh suhu dan kelembaban melainkan dipengaruhi oleh aktifitas yang berada disekitar.

Abstract

Sejumlah 7 (tujuh) satelit telekomunikasi di orbit geostasioner (GEO) milik perusahaan Indonesia beroperasi meliput wilayah Indonesia; walaupun cakupan footprint beberapa satelit telekomunikasi geostasioner yang dioperasikan operator telekomunikasi Indonesia sudah meliput seluruh luas wilayah Indonesia secara sempurna, akan tetapi tetap saja konektivitas sebagian populasi masyarakat di Indonesia belum terakomodasi, terutama wilayah 3T (terluar, tertinggal, terdepan), terpencil dan/atau pulau-pulau kecil.  Alasan kapasitas satelit nasional yang sudah penuh adalah sebab Pemerintah cq. Kominfo menyewa satelit asing untuk penambahan kapasitas penyediaan layanan satelit komunikasi agar konektivitas sebagian populasi masyarakat bisa dipenuhi.  Solusi alternatif mengatasi kekurangan konektivitas dan kapasitas tersebut adalah diversifikasi sistem komunikasi satelit di orbit LEO selain satelit di orbit GEO.   Alasannya karena biaya investasi konstelasi satelit LEO lebih rendah dibanding satelit GEO, selain harga end-user terminalnya juga lebih kecil dan murah, selain itu keunggulan berupa delay propagasi yang rendah dan daya transmisi yang lebih rendah.  Studi perancangan simulasi konstelasi satelit LEO untuk menambah konektivitas dan kapasitas satelit nasional digagas untuk populasi masyararakat tadi saja.  Harapannya konstelasi satelit LEO dapat menyediakan konektivitas berupa layanan internet bagi populasi masyarakat yang kepadatan penduduknya (user density) 500 – 1000 orang per-km persegi dan wilayah terpilih adalah pulau-pulau kecil di wilayah Timur Indonesia.
