Abstract

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.

Abstract

Nyamplung (Calophyllum Inophyllum) is an environmentally friendly alternative fuel that can be used to replace the consumption of fossil fuels. The purpose of this experiment was to analyze the effect of magnetic fields on the premixed flame of biodiesel from Calophyllum Inophyllum, the experiments were carried out on a bunsen burner. Fuel evaporation uses a temperature of 473 K and the equivalent ratio used is between ϕ 0.7; 0.8; 0.9; 1.0; 1.1 and 1.2. This experiment used a modified magnet that has magnetic force in 11.000 gausses with magnetic variations N-S, S-N, N-N, and S-S. Experiments revealed that magnetic fields have a significant effect to increase the value of laminar flame speed on magnetic variations point at S-S 3.8%; N-N 4.8%; S-N 17.09%, and the highest laminar flame speed were at point N-S 20.7%. The enhancement value of laminar flame speed indicated more optimum combustion processes. The magnetic fields can influence the O2, and H2O and change the orientation of the hydrocarbons which makes it easier for O2 and fuel to carry out the oxidation process, resulting in more optimal combustion.

Abstract

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence of a magnetic fields. To conduct the experiment, a bunsen burner was utilized, with fuel and air being dispensed via a syringe pump and compressor, both regulated by a flowmeter. The fuel and air pipes were heated to 532.15 (K) to facilitate fuel evaporation. The equivalent ratio of 0.5, 1, and 1.5 was adjusted to control air discharge and fuel. An 11,000 gausses artificial magnet was used, with N-S, N-S, N-N, and S-S being the various magnetic pole configurations. The study found that the magnetic field can enhance combustion quality by affecting the molecules involved in the combustion process. The magnetic field's force also intensifies the movement of O2, making it more energetic. As O2 travels from the North Pole to the South Pole through the combustion reaction zone, it quickens the oxidation-reduction process and curtails diffusion combustion. The red color's intensity diminishes with the magnetic field's effect, indicating this phenomenon. When a magnetic field is applied, the polarity of C.inophyllum biodiesel fuel becomes highly favorable. The triglyceride carbon chain bonds become unstable, and the van der Walls dispersion forces are weakened, which facilitates easier O2 binding to the fuel, resulting in more efficient combustion. An increase in the laminar burning velocity value can be noticed when exposed to a magnetic field.

Abstract

The Silo subdistrict is one of the coffee-producing villages, with a production amounting to more than 40% of the total coffee production in Jember Regency. The coffee processing produces coffee husk waste, which is often discarded into the environment and potentially causes pollution. Coffee husk waste has a high calorific value and is suitable for use as biomass fuel to produce syngas through gasification methods. The partner for this community service is GAPOKTAN Suka Maju, located in Pace Village, Silo Subdistrict, Jember Regency. GAPOKTAN Suka Maju is led by Mr. Zainal Arifin, who has 30 members. This community service aims to provide knowledge to GAPOKTAN Suka Maju members about the environmental impact of coffee husk waste disposal and the utilization of coffee husk waste as an energy source through gasification methods. The community service method consists of pre-activities, activity implementation, and evaluation. The pre-activities include designing the gasification equipment, making the gasification equipment, and drying the coffee husk waste. The implementation consists of socializing the environmental impact of coffee husk waste disposal, the energy potential of coffee husk waste, and training in gasification equipment. The results show a significant increase in the participants' understanding of the environmental impact of coffee husk waste disposal, the energy potential of coffee husk waste, and the gasification method and equipment to convert coffee husk waste into fuel.
