Nano γAl2O3 has been one of the nanometal oxides that has improved the characteristics of biodiesel. The effect of γAl2O3 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 γAl2O3 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 ϕ = 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 ϕ = 0,76 -1,17. CIME30 with nanoparticles, flame stable between ϕ = 0,67 -1,17. Combustion of CIME30 required a lot of air. The highest laminar flame speed occurred at the equivalent ratio ϕ = 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 γAl2O3 concentration the higher the laminar flame speed. This occurs due to the catalytic effect of γAl2O3 on biodiesel and its mixtures.

Kepuh biodiesel fuel (sterculia foetida) is an alternative fuel that can be used to replace fossil fuel. Diesel fuel is performed to determine the laminar burning velocity and high flame by adding biodiesel kepuh volume of 10%, 20%, 30%. The purpose of this study was to study the effect of biodiesel and the effect of bunsen burners on the laminar burning velocity and flame height. Bunsen burner is made of copper and stainless steel. Testing of flame characteristics was carried out by heating the mixture of fuel and air at a temperature of 200°C. The purpose of heating the air is to prevent cooling when mixed with fuel. The mixture of fuel and air flowed into the mixing chamber and bunsen burner. The mixture of fuel and water flows into the mixing chamber and bunsen burner to form a fire. Flame images were recorded using a high-speed fuji film camera with a speed of 480 fps with a resolution of 224x168. The test results were analyzed by measuring the angle and height of the flame using the freeware ImageJ program. The results of the B0 (diesel oil without the addition of biodiesel) fuel mixture test using copper bunsen burner produced a maximum laminar flame speed of 23.626 cm/s at φ = 0.8. The highest value of the B30 fuel mix flame (30% biodiesel + 70% diesel oil) produces a maximum flame value using a stainless steel bunsen burner with a value of 25.417 mm at φ = 1.2. The results showed that B0 in copper bunsen burner had the highest laminar burn rate. The composition of the fuel and bunsen burner affects the combustion characteristics and flame height.

Puger Wetan is the largest fisheries center in Jember. One of the fish type produced is SardinellaLemuru. Due to its small size and prickly nature, it is rarely consumed directly. It is commonly sold as raw material for canned sardines. Canned sardines manufacture needs fresh Lemuru, because it will cause itching on the tongue if not fresh. Whereas, fishermen mostly piled the fish in the boat hatch then gave ice cubes, so that the majority of it will no longer be fresh when arrived in the mainland because its perishable nature due to its thin skin.As the result, most of fishermen's catch is not feasible for canned sardines and become leftovers. During this time, it will be sold at a low price. Fish leftovers that are not absorbed by the market aredumped into the river, becomingleftovers. The waste pollutes the environment and harms the health and hygiene. There will be more wastes during the fishing season, as more and more lemuru leftovers are dumped. This activity aims to resolve the problem by transforming the leftovers into fish meal, using appropriate tech machines. The activities are carried out in several stages. The first stage is the counseling about the negative impact of fisheries waste and the possibility of utilizing it into fish meal, also about the business opportunity that is still potential because domestic demand is still not yet met. The explanation of the importance of business management was also given.The third stage is the practice of making fish meal with the help of tools that have been previously converted technology. The fourth stage is the evaluation of activities for the benefit of partnering groups. Lemuru leftover utilization into fish meal is one of the important components in animal feed which can increase the fishermen income, while reducing environmental pollution.

Pengendalian kualitas merupakan sebuah teknik yang dapat dilakukan mulai dari tahap sebelum proses produksi hingga proses produksi berakhir. Six sigma merupakan sebuah metodologi terstruktur untuk memperbaiki proses dengan menggunakan statistik dan problem solving tools secara intensif menuju target 3,4 kegagalan per satu juta kesempatan. PT. X bergerak di bidang industri pembuatan kaleng makanan dengan salah satu produknya adalah kaleng tipe two piece cans 307. Berdasarkan informasi perusahaan, pada proses produksi kaleng tipe tersebut seringkali ditemukan produk mengalami cacat yang merugikan perusahaan. Penelitian ini dilakukan untuk mengetahui bagaimana cara yang tepat untuk meminimalkan cacat kaleng tipe tersebut dengan menggunakan metode six sigma. Hasil penelitian diketahui bahwa penyebab utama cacat adalah pekerja kurang teliti, setting clearence dies yang terlalu rapat, dies kemasukan afval, pisau press tumpul, bahan kotor dan rusak, perawatan mesin yang tidak dilakukan secara berkala, area produksi tidak rapi dan bising. Nilai DPMO sebesar 2844 yang dikonversikan kedalam sigma level yakni 4.27. Usulan perbaikan dengan Five-M Checklist meliputi memberikan pelatihan dan memperketat pengawasan kepada pekerja, melakukan setting mesin sesuai prosedur serta ubah clearence dies menjadi 0,24 mm, memperketat pemeriksaan bahan baku kaleng, melaksanakan perawatan mesin sesuai dengan jadwal yang telah ditentukan, menjaga kebersihan dan kerapian area produksi. Quality control is a technique that can be carried out from before the production process until the production process ends. Six sigma is a structured solution to process improvement using statistics and problem solving tools that intensively reach the target of 3.4 recovery per one million opportunities. PT. X is engaged in the industry of making cans with one of its products is a 307 two-piece can. Based on company information, in the production process, cans are found to find products that can save the company. This research was conducted to find out the right way to overcome this type of defect by using the six sigma method. The results of the study are known to be related to the fact that workers do not have meticulous, clear dead settings that are too tight, afval conceded dies, blunt press blades, dirty and damaged materials, machine maintenance that is not officially done, production area is not neat and noisy. The DPMO value is 2844 which is converted into sigma level which is 4.27. Proposed improvements with the Five-M Checklist provide training and tighten supervision to workers, make machine arrangements according to procedures and change clearly to 0.24 mm, tighten inspection of tin raw materials, manage engine maintenance according to agreed schedules, care about cleanliness and neatness production area.
