Perfect combustion can improve engine performance and save fuel consumption. One of the requirements perfect combustion is a homogeneous mixture of fuel and air when entering the combustion chamber. Air and fuel mixture to become homogeneous in case of turbulence in the mixing. Buffer with director fin is used to provide additional mixing time between air and fuel at the same time create a turbulent flow before entering the combustion chamber. In this study the buffer fitted with director fins with different variations. The number of fins variation used in this study are 3, 4, 6, 8 and 10 with a variation of the angle are 45o and 60o. The analysis was conducted on the effective power and torque output and the FC (Fuel Consumption) needed from each variation condition buffer. From the results of testing on the condition of the buffer with 3 fins angled 60o obtain the highest effective power increase 5.92% and increase in the highest torque 2.66% when compared with the buffer without fins. The lowest FC (Fuel Consumption) in the buffer with 3 fin angle 60 Â° when compared with the buffer without any fins at 4000 rpm with a 11.15% difference. Keywords: homogeneous, turbulent, buffer and fin

Research on premixed butane combustion has been carried out, to determine the characteristics of flame velocity and ion concentration. The research was carried out by combining premixed butane mixture in a cylindrical combustion chamber measuring 108 mm in diameter and 170 mm in length. The premixed butane air mixture is set at the equivalent composition ratio  = 0.8; 0.9; 1.0; 1.1; 1,2. The results showed that the highest flame speed was equivalent to a ratio of 1.1, which was 198 cm / s whereas the highest radical concentration indicated by the voltage on the ion sensor system is equivalent to a ratio of 1.1, which is 5.5 volts. Keywords: butane, flame velocity, radical concentration, premixed combustion

Experimental Study on the Effect of Nano Additives Î³Al2O3 and Equivalence Ratio to Bunsen Flame Characteristic of Biodiesel from Nyamplung (Calophyllum Inophyllum) Setyo Pambudi; Nasrul Ilminnafik; Salahuddin Junus; Muh Nurkoyim Kustanto

Nano Î³Al2O3 has been one of the nanometal oxides that has improved the characteristics of biodiesel. The effect of Î³Al2O3 nanoparticles addition on premixed flame combustion is investigated with an experiment on the laminar flame speed of Calophyllum inophyllum methyl ester 30% and 70% petrodiesel mixtures, at atmospheric pressure and preheated temperature T = 473K. The Î³Al2O3 nanoparticles added to CIME30 biodiesel were 0ppm, 100ppm, 200ppm, and 300ppm. Experiments were carried out on a bunsen burner. The equivalent ratio of the mixture between Ï• = 0.67 to 1.17. Experiments revealed that the addition of nanoparticles to CIME30 biodiesel expands the flammability limit and increases the laminar flame speed. CIME30 without nanoparticles, flame stable between Ï• = 0,76 -1,17. CIME30 with nanoparticles, flame stable between Ï• = 0,67 -1,17. Combustion of CIME30 required a lot of air. The highest laminar flame speed occurred at the equivalent ratio Ï• = 0.83. The highest laminar flame speed of CIME30 0, 100, 200, and 300 ppm were 30.77, 34.50, 35.90, 38.45 cm/s respectively. The higher the nano Î³Al2O3 concentration the higher the laminar flame speed. This occurs due to the catalytic effect of Î³Al2O3 on biodiesel and its mixtures.

Spray characteristics have an important role in improving the quality of combustion in compression engines. This study analyzes the effect of ambient temperature on spray characteristics including spray tip penetration, spray angle and velocity of spray. The research method uses an experimental method with ambient temperature variations of 60oC, 80oC, 100oC controlled using a thermocouple and an ambient pressure of 0.3 MPa. the composition of the fuel uses diesel (diesel 100%), B30 (30% biodiesel), B100 (100% biodiesel). Image recording using camera speed 480 fms. Based on the experimental results, the ambient temperature increases the spray angle and B100 at all ambient temperatures has a spray tip penetration, velocity of spray is lower.

Separation condenser is one of the types of condenser equipped with gas and liquid separator. The previous research using separation condenser showed low output temperature of 1.3 K than baseline condenser. This study is to observe the effect of separation and baseline condenser to the performance of the refrigerator with a double evaporator and using LPG and R134A as a refrigerant. This research using a parallel circuit for separation condenser and baseline. The result showed that using R134A gives 0.16% higher value of COP. Meanwhile, using double evaporator with R134A as a refrigerant gives 69.5 % higher value of COP than single evaporator.

An electric car is a vehicle that is driven by an electric motor, the electric motor obtains power from electricity stored in the battery. Chassis is an important component in electric cars. Chassis is part of an electric car that functions as a support system in an electric car. In the chassis there is a maximum and minimum stress called the principal stress. This principal stress becomes a reference to determine the safety of the chassis. So it is necessary to know the principal stress on the chassis. The testing process uses two drivers, each of which weighs 45 kg and 56 kg. The tests were carried out at three different points on the electric car chassis. From the results of the principal stress test, σ1 = 3.3282 MPa and σ2 = 1.5429 MPa for the 45 kg driver and σ1 = 3.8233 MPa and σ2 = 2.1123 MPa for the 56 kg driver. The principal stress on the chassis is still in a safe condition because it does not exceed the yield stress of the chassis material.

Seiring kenaikan konsumsi energi minyak dan menurunnya cadangan minyak bumi, maka perlu beralih ke minyak nabati sebagai sumber bahan bakar terbarukan, salah satunya adalah dari biji nyamplung. Biji nyamplung banyak terdapat di desa Kebondalem, Kecamatan Bangorejo, Kabupaten Banyuwangi. Pengabdian masyarakat ini bertujuan mengenalkan potensi minyak nyamplung ke masyarakat desa tersebut. Kegiatan pengabdian dilakukan oleh tim gabungan dosen dan mahasiswa jurusan Mesin, Fakultas Teknik, Universitas Jember. Kegiatan berupa pengenalan potensi biji nyamplung untuk alternative bahan bakar, dilanjutakn dengan peragaan pengepresan biji menjadi minyak. Di sela-sela kedua acara teresbut diselingi tanya jawab dan diskusi. Hasil dari pengabdian ini cukup membuka wawasan warga desa yang hadir akan potensi nyamplung yang selama ini terabaikan. Tokoh masyarakat dan karang taruna siap untuk menindaklanjuti kegiatan ini dengan rencana penanaman lahan hutan desa dengan nyamplung. Perlu arahan dan kegiatan lanjutan untuk menyambut antusiasme warga desa ini.
