PT. XYZ is a manufacturing company that produces grey fabrics, it can be customized by the customers. In order to increase productivity and quality production, the company trying to develop business by adding some machines with the latest type and technologies. Based on direct observations, Company produced a lot of defects and causes a negative impact. The problem can be solved by 4 quality control methods (exist in seven tools method) check sheets, pareto diagrams, control charts, and fishbone diagrams. This method used to determine the root of problems related with the quality products. Check sheet method analysis shown intensity categories of product defects with label "always", "often" and "rarely". Then, the analysis of pareto diagrams showing the most dominant types of defects, with the name "Loncat P / L" and "Ambrol". Furthermore, the results of the control chart analysis show an uncontrolled status. Finally, it can be known that the problem causing product defects is quality of dirty raw materials, machine failure, labour fatigue, poor work methods and unhealthy environment. recommendations given by researchers to the company are further tighten SOP implementation, control and supervise workforce performance, workforce briefings, and pay attention to 5S work culture.

The vehicle fuel consumption is increasing. Fossil fuels are running low. Research is needed to reduce the use of fossil fuels. As an alternative, research is carried out on the use of a mixture of bio-oil - diesel fuel in diesel engines. The aim of the research is to increase power, reduce fuel consumption and reduce exhaust emissions from diesel engines. The research method is direct testing on diesel engines with variations in fuel heating by adding a heater to the fuel. Variation of heating materials The fuel used is standard temperature, 40°C, 50°C, and 60°C. The test uses a lamp load with a certain variation to determine power, with a measuring tube to determine certain fuel consumption. Testing using the opacity smoke meter to determine the level of exhaust gas opacity. In this test, In this test it can be concluded that the best condition is B20 at a fuel heating temperature of 40oC, where power has increased, opacity and fuel consumption has decreased, the power can reach 2592,76 watt. Smoke opacity level at 5,4% and 0,088 gr/watt of fuel consumption.

Pyrolysis is a decomposition process chemical ingredient by adding the heating process without oxygen, where is the raw material/biomass will experience the breakdown of chemical structures to the gas phase. It produced char, tar, and gas. This research uses a rotary kiln system, in which the pyrolysis tube is rotated at low speed. Biomass in a rotating pyrolysis tube has an even heat. The pyrolysis temperature used in this research is 523K, 57K, 623K, 673K, The heat in the pyrolysis tube comes from heating the LPG stove. The heating is adjusted in such a way that the heat can be reached at the desired temperature. The tar formed in the pyrolysis process is calculated its kinetic rate value. The biomass used in this study is a waste of brem, plastic, and durian skin. The results showed that with increasing temperature, the tar volume would increase. The value of the kinetic rate is strongly influenced by variations in pyrolysis temperature. The pyrolysis temperature is large, so the kinetic rate is also large. The best kinetic rate at a temperature of 673 K in all biomass. The type of biomass can affect the kinetic rate. Plastic waste biomass has the smallest kinetic rate value compared to other biomass. The density of bio-oil will decrease with increasing pyrolysis temperature.
