An increase in flight frequency can have a negative impact on the surrounding environment, one of which is high noise levels. Noise can come from full activity, runway stay, movement towards the runway, or aircraft engine testing. Airplane noise during take-off is one of the environmental problems that need attention at airports. The height of the aircraft's trajectory during take-off can affect the noise level generated by the aircraft, but not much research has been conducted to measure the impact of variations in the height of the disturbance on the noise level of aircraft at Halim Perdanakusuma Airport. This study aims to measure the noise level of aircraft during take-off with variations in track height at Halim Perdanakusuma Airport. The method used in this study is to observe 4 aircraft taking off at Halim Perdanakusuma Airport with a research time of 3 days, and the measuring instrument used is a sound level meter. Sound level meters measure noise in dBA units between 30 and 130 dB at a frequency of 20 to 20.000 Hz. Based on the calculation and measurement results obtained, it is known that the maximum height when the measurement is on the second day is at point A of 277 meters, while at point B is 299 meters. While the highestnoise measurement at point A is 93,1 dB while at point B it is 91,5 dB. The measured noise value based on calculations is estimated at 66,2 dB and is still below the Airbus A320 aircraft noise certification for flyover takeoff of 73,7 dB.

Tulisan ini menginformasikan tentang kebutuhan sumber alternatif pengganti bahan bakar fosil untuk pesawat (Avtur). Peningkatan kebutuhan energi terus terjadi dan di sisi lain jumlah energi yang bersumber dari fosil terus menurun, maka perlu dilakukan upaya diversifikasi energi, yaitu upaya pemanfaatan energi alternatif. Berdasarkan Renstra Kementerian ESDM Tahun 2015–2019, cadangan minyak bumi Indonesia sebesar 3,6 miliar barel diperkirakan akan habis dalam 13 tahun mendatang. Menteri Perhubungan (2009–2014) E. E. Mangindaan mengatakan pemanfaatan bahan bakar nabati dan energi terbarukan bagi sektor transportasi secara khusus juga mendorong peningkatan konten lokal baik dari aspek penguasaan riset, teknologi dan aplikasi dari hulu hingga ke hilir di dalam seluruh mata rantai suplai, produksi dan distribusi. Gagasan untuk menggunakan mikroalga sebagai sumber bahan bakar bukanlah hal baru, tetapi sekarang dianggap serius karena kenaikan harga minyak bumi dan lebih penting lagi, masalah yang muncul tentang pemanasan global dan efek rumah kaca yang terkait dengan pembakaran bahan bakar fosil. Kelebihan yang dimiliki oleh mikroalga bila dibandingkan dengan tanaman lainnya yaitu efisiensi fotosintesis yang tinggi, menghasilkan biomassa yang lebih banyak, pertumbuhan lebih cepat, tidak berkompetisi dengan produksi pangan, mengurangi emisi gas rumah kaca, dapat mengubah CO2 menjadi biomassa, mempunyai komponen sampingan selain lipid, dapat menghemat sumberdaya air karena menggunakan air hasil daur ulang, dapat bertahan dalam salinitas yang tinggi, 10-100 kali menghasilkan biodisel dibanding tanaman lain untuk luas yang sama, siklus hidup yang lebih singkat dan sesuai dengan iklim Indonesia. This paper informs about the need for alternative sources of substitute for fossil fuels for aircraft (Avtur). Increasing energy needs continue to occur and on the other hand the amount of energy sourced from fossils continues to decline, it is necessary to do energy diversification efforts, namely efforts to use alternative energy. Based on the ESDM Ministry Strategic Plan for 2015-2019, Indonesia's oil reserves of 3.6 billion barrels are expected to run out in the next 13 years. The Minister of Transportation (2009-2014) EE Mangindaan said that the use of biofuels and renewable energy for the transportation sector in particular also encouraged the increase of local content both from the mastery of research, technology and applications from upstream to downstream in all supply chains, production and distribution. The idea of using microalgae as a fuel source is not new, but is now taken seriously because of the increase in petroleum prices and more importantly, the problems that arise about global warming and the greenhouse effect associated with burning fossil fuels. The advantages of microalgae compared to other plants are high photosynthetic efficiency, producing more biomass, faster growth, not competing with food production, reducing greenhouse gas emissions, can convert CO2 into biomass, have a side component other than lipids, can save water resources because it uses recycled water, can survive in high salinity, 10-100 times produce biodiesel compared to other plants for the same area, a shorter life cycle and in accordance with Indonesia's climate.

The high usage of air transportation today is driven by the community's need for faster and more efficient mobility. However, the impact of using aircraft cannot be ignored, especially in terms of noise pollution caused by aircraft engines. Halim Perdana Kusuma Airport, which was originally designed for military activities, has become a commercial airport since 2014 in an effort to reduce flight density at Soekarno-Hatta Airport. This study aims to measure aircraft noise around Halim Perdana Kusuma Airport by including frequency. Measurements were carried out using a dB meter application downloaded on a mobile phone and a Sound Level Meter, both during flight activity and without flight activity in surrounding settlements. The results of this study indicate that noise in dBA can be measured with a Sound Level Meter, while frequency can be measured with a smartphone that has a dB meter application installed. The highest frequency measured during aircraft take-off activity at Halim Perdana Kusuma Airport peaked at 7716 Hz to 7834 Hz, when the noise reached its highest point. From this research, it can be concluded that the higher the frequency The higher the frequency the smaller ∆LA, meaning the dBA is getting closer to the sound pressure level.
