Desain Kapal Motor Penyeberangan dengan Sistem Penggerak Hibrida untuk Rute Ujung Surabaya-Kamal Bangkalan
'Lembaga Penelitian dan Pengabdian kepada Masyarakat ITS', 2017Co-Authors: Agustin Dwi, Kurniawati, Hesty AnitaAbstract:The condition of crossing from Ujung to Kamal make loss to PT. ASDP that they plan to close this route. One of the many factors is high operational cost. Besides that, Surabaya is one of the cities in Indonesia with high Emission Gas. This final project gives solutions to reduce Emission Gas and reduce the use fossil fuel with hybrid-propulsion concept. The type of hybrid used in this final project are diesel engine, hydrogen fuel cell, and solar panel cell. Payloads of this passenger ship is the amount of passenger crossing from Ujung-Kamal of PT. ASDP. From that data, an initial design is made to determine deck area payload (passenger deck and vehicle deck) so that the main dimension of the vessel is obtained from the decks layout. In continuance, ratio of main dimensions are calculate. There should be a technical calculation concerning on weight, trim, freeboard, and stability. The main dimension calculated are Lpp =42 m; B = 6.9 m; H = 3 m; T = 2 m. The minimum freeboard height is 150 mm, tonnage capacity is 295 GT, and the stability condition of the Passenger Ship has passed the criteria of Intact Stability (IS) Code Reg. III/3.1). The ship building cost is Rp 13,173,344,991.91 with the BEP on the 68th month, so the ship is feasible to be built

Desain Kapal Motor Penyeberangan dengan Sistem Penggerak Hibrida untuk Rute Ujung Surabaya-Kamal Bangkalan
2017Co-Authors: Agustin DwiAbstract:Kondisi Penyeberangan Ujung-Kamal yang semakin sepi penumpang membuat Pengusaha ASDP terus merugi hingga berniat menutup jalur penyeberangan ini. Salah satu faktor penyebab adalah tingginya biaya operasional untuk bahan bakar BBM. Selain itu, Surabaya merupakan salah satu kota dengan tingkat emisi Gas buang yang tinggi dari kendaraan bermotor dengan bahan bakar BBM. TuGas Akhir ini bermaksud memberikan solusi untuk mengurangi jumlah emisi Gas buang serta bisa menghemat pemakaian bahan bakar BBM dengan memasukkan konsep kapal dengan sistem penggerak hibrida. Jenis hibrida yang digunakan adalah mesin diesel, hydrogen fuel cell, dan solar panel cell. Payload dari Kapal Motor Penyeberangan ini merupakan jumlah pengguna jasa angkutan Ujung-Kamalyang diperoleh dari PT. Angkutan Sungai Danau dan Penyeberangan (ASDP). Kemudian dari jumlah pengguna jasa angkutan dibuat gambar awal untuk menghitung payload luasan geladak(geladak penumpang dan kendaraan), sehingga didapatkan ukuran utama kapal dari layout geladak penumpang dan kendaraan.Setelah itu dilakukan perhitungan teknis berupa perhitungan berat, trim, freeboard, dan stabilitas. Ukuran utama yang didapatkan adalah Lpp = 42 m; B = 6.9 m; H = 3 m; T = 2 m. Tinggi freeboard minimum sebesar 150 mm, besarnya tonnase kapal adalah 295 GT, dan kondisi stabilitas Kapal Motor Penyeberangan memenuhi kriteria Intact Stability (IS) Code Reg. III/3.1. Biaya pembangunan kapal baru sebesarRp 13,173,344,991.91dengan BEP pada bulan ke-68, sehingga kapal ini layak untuk dibangun. ==================================================================== The condition of crossing from Ujung to Kamal make loss to PT.

PENGUJIAN PENGGUNAAN ALAT PENGHEMAT BBM PADA MESIN BERBAHAN BAKAR BENSIN DAN SPIRITUS DITINJAU DARI ASPEK TEMPERATUR
2010Co-Authors: Saputra Mohamad Hadi, Arijanto Arijanto, Setiyana BudiAbstract:This experiment is entitled “Fuel Saver Device Test on Gasoline And Methylated Spirit Engine Reviewed From Temperature “. One of the solution to save fuel is the use of alternative fuel and fuel saver device. The research is to find an alternative to petroleum. The experiment tested the use of Gasoline – Methylated Spirit mixed fuel with the percentage of Methylated Spirit (80%-20%) for Daihatsu Classy 1295 cc. The fuel saver device used is called “Elektrolizer HHO (Gas Brown)”. Such device has been commonly used lately.The purpose of the study was to find out the effect of the use of Elektrolizer HHO by not using it for mixed Gasoline – Methylated Spirit fuel, from the aspect Emission Gas temperature. The calculation included the consumption of fuel and air, rate of AFR, and the temperature of combustion. The result of the experiment was the decrease of fuel consumption by 13%. From the Emission Gas temperature increased by 0,4% to 4,7%, therefore, it decrease the viscosity of lubricating oil and increased the metal content. The conclution was drawn from the result of viscosity test

PENGUJIAN PENGGUNAAN ALAT PENGHEMAT BBM PADA MESIN BERBAHAN BAKAR BENSIN DAN SPIRITUS DITINJAU DARI ASPEK EMISI Gas BUANG
2010Co-Authors: Prasetyo Muhamad Budi, Arijanto ArijantoAbstract:Generally in Indonesia, motor vehicle was consuming Gasoline for the Gasoline engine and diesel fuel for the diesel engine, but have to be seen that both of the fuel is petroleum distillate which is the include in natural resoure which cannot be renewable. Spiritous is one of fuel which possible could be the alternative fuel or additive Gasoline to the future. Spritous including in alcohols with the most simplest chemical formula (CH3OH) This experiment is entitled “Used of Fuel Saver Device Test on Gasoline And Methylated Spirit Engine Reviewed From exhause Emission “. One of the solution to save fuel is the use of alternative fuel and fuel saver device. The research is to find an alternative fuel besides petroleum. The purpose of the study was to find the effect of using Elektrolizer HHO and not using for mixed Gasoline – Methylated Spirit fuel, from the aspect Emission Gas. The calculation included the consumption of fuel and air, and rate of AFR

fuel flexible distributed combustion for efficient and clean Gas turbine engines
Applied Energy, 2013Co-Authors: Ahmed E E Khalil, Ashwani K GuptaAbstract:The need for fuel flexible ultra-low Emission Gas turbine combustors is imminent to secure future power needs. Distributed combustion technology is demonstrated to provide significant performance improvement of Gas turbine combustors including uniform thermal field in the entire combustion chamber (improved pattern factor) at very high combustion intensity, ultra-low Emission of NOx and CO, low noise, enhanced stability, higher efficiency and alleviation of combustion instability. Distributed reaction conditions were achieved using swirl for desirable controlled mixing between the injected air, fuel and hot reactive Gases from within the combustor prior to mixture ignition. In this paper, distributed combustion is further investigated using a variety of fuels. Gaseous (methane, diluted methane, hydrogen enriched methane and propane) and liquid fuels, including both traditional (kerosene) and alternate fuels (ethanol) that cover a wide range of calorific values are investigated with emphasis on pollutants Emission and combustor performance with each fuel. For liquid fuels, no atomization or spray device was used. Performance evaluation with the different fuels was established to outline the flexibility of the combustor using a wide range of fuels of different composition, phase and calorific value with specific focus on ultra-low pollutants Emission. Results obtained on pollutants Emission and OH* chemiluminescence for the specific fuels at various equivalence ratios are presented. Near distributed combustion conditions with less than 8PPM of NO Emission were demonstrated under novel premixed conditions for the various fuels tested at heat (energy) release intensity (HRI) of 27MW/m3-atm. and a rather high equivalence ratio of 0.6. Higher equivalence ratios lacked favorable distributed combustion conditions. For the same conditions, CO Emission varied for each fuel; less than 10ppm were demonstrated for methane based fuels, while heavier liquid fuels provided less than 40ppm CO Emissions. Lower Emissions of NO (<4.5PPM) were also demonstrated at lower equivalence ratios. This demonstration outlines the combustor ability for fuel flexibility without any modifications to the combustor injectors, while maintaining high performance. Further reduction of NOx can be possible by establishing true distributed combustion condition, in particular at higher equivalence ratios.
