Siagian, Dedy Pribadi (2018) Pengaruh Kadar Uap Air Terhadap Kecepatan Api Laminer dengan Bahan Bakar Gas Metana. Sarjana thesis, Universitas Brawijaya.

Indonesian Abstract

Sekarang ini kebutuhan akan bahan bakar semakin meningkat, oleh karena itu bahan bakar semakin sulit dicari atau langka. Keterbatasan bahan bakar yang tidak dapat diperbaharukan menjadi persoalan karena bahan bakar ini tidak lepas dari kehidupan kita, jika pemerintah mengekplorasi secara berkelanjutan akan menimbulkan masalah yang lebih besar yaitu krisis bahan bakar. Karena itu banyak penelitian penelitian ilmiah yang mencari solusi atas permasalahan krisis bahan bakar dengan mencari bahan bakar alternatif sebagai energi terbarukan yang ketersediaan di alam masih cukup. Metana dapat digunakan sebagai bahan bakar alternatif karena persediaannya yang masih mencukupi, ramah lingkungan dan masih mudah didapat di masyarakat Kecepatan api laminer merupakan sebuah parameter penting dalam masalah pembakaran dikarenakan berisi informasi mendasar mengenai reaktivitas, difusivitas, dan exothermicity. Kecepatan api laminer dipengaruhi juga oleh uap air. Uap air adalah gas yang berasal dari proses pemanasan air (H2O). Disamping itu kadar uap air lingkungan dapat mempengaruhi pembakaran. semakin besar kadar uap air dalam sebuah daerah maka panas yang dihasilkan pembakaran akan semakin tinggi. Maka dari itu perlu dilakukan penelitian untuk mengetahui pengaruh kadar uap terhadap kecepatan api laminer gas Metana. Pada penelitian ini menggunakan bunsen burner dikarenakan pembuatan alat yang juga relatif lebih mudah. Variabel bebas pada penelitian ini adalah nilai equivalence reaktan sebesar: 0,762; 0,802; 0,923; 1,05; 1,128; 1,385 dan kadar uap air sebesar: 7,35%; 13,70%; 16,56%; 19,23%; 21,74%; 24,10%; 28,41%. Hasil penelitian menunjukan bahwa kecepatan api laminer ( SL) menurun seiring meningkatnya kadar uap air, selain itu semakin tinggi equivalence ratio maka kecepatan api laminer (SL) semakin menurun, tinggi api semakin menurun, sedangkan temperatur nyala api meningkat sampai equivalence ratio mendekati 1 kemudian kembali turun seiring kenaikan equivalence ratio.

English Abstract

Nowadays the need for fuel is increasing, because the fuel will be more difficult to find or rare. Limitations of non-renewable fuels are a problem as these fuels can not be separated from our lives, if the government explores sustainably it will lead to a bigger problem of fuel crisis. Therefore, many scientific research are looking for solutions to the fuel crisis problem by finding alternative fuels as renewable energy whose availability in nature is still sufficient. Methane can be used as an alternative fuel because its supply is still sufficient, environmentally friendly and still easily obtainable in the community The fire rate of laminer is an important parameter in the burning problem because it contains basic information about reactivity, diffusivity, and exothermicity. The fire rate of laminer is also affected by water vapor. Water vapor is a gas that comes from the heating process of water (H2O). In addition, the moisture content of the environment can affect combustion. the greater the moisture content in an area the heat generated by combustion will be higher. Therefore it is necessary to conduct a research to determine the effect of steam to the velocity of methane laminer fire. In this study using Bunsen burner due to the making of the tool is also relatively easier. The independent variable in this research is the Equivalence Value of reactant equal to: 0,762; 0.802; 0.923; 1.05; 1,128; 1.385 and moisture content of: 7,35%; 13,70%; 16,56%; 19,23%; 21,74%; 24,10%; 28,41%. The results showed that the velocity of laminer fire (SL) decreased with increasing moisture content, besides the higher the equivalence ratio then the laminer fire rate (SL) decreased, the fire height decreased, while the flame temperature increased until the equivalence ratio was close to 1 then back down as the equivalence ratio increases.
