The use of lubricating oil is increasing every year the resulting waste is also increase. Based on the waste criteria issued by the Ministry of Environment, used oil is included in the category of B3 waste. Although used oil can still be used, if not managed properly, it can be dangerous for the environment. The result of this is higher energy prices and decreased oil supply. The process in this research is to treat the used oil waste with heat treatment methods and compare the results and the process of treating used oil waste using a catalyst and without using a catalyst. Then the sample results were tested and compared with existing fuel standards. The catalyst has been shown to affect the process and the resulting results in the used oil processing process. It can be seen in the discussion of the process using a catalyst to produce oil products faster than from the process without using a catalyst, and also the product produced in the process using a catalyst is more and of better quality than the product produced without using a catalyst. There it proves that the function of the catalyst works well, namely as an accelerator of the reaction rate and increasing the desired reaction results.

This study aims to obtain optimal porosity results from bone scaffolding printing using FDM type 3D printing machines using PLA material. In this study, the bone scaffold was modeled using Solid Works. This research's main contribution is to obtain optimal settings in the molding of bone scaffolding using the Taguchi method. The Taguchi method is used based on its efficiency; this is because orthogonal arrays require fewer experiments than experimental designs. Analysis of variance is needed to see the factors that have a significant effect on the response variable. The results showed that the factors that significantly affected the bone scaffold's porosity quality were 42.22% nozzle temperature, 10.81% layer thickness, and 0.78% printing speed, respectively. The optimal operating parameter settings are at a nozzle temperature of 210oC, a printing speed of 25 mm/s, and a layer thickness of 0.1 mm, which are ideal settings for printing bone scaffolds so that porosity deviations can be minimized.

The purpose of this research is to obtain bioplastics that are biodegradable and safe if disposed of in the environment. This bioplastic is made using Empty Bunches and white rice and plasticizer. White rice flour as a source of starch with variations in the addition of chitosan additives and glycerol plastilizer. The analysis of the biodegradable plastic products produced was tested for physical and mechanical characteristics such as thickness, water resistance test (%), biodegradation rate (%), and tensile strength (MPa). The method used is by mixing the starch from the mixture of empty bunches and white rice and adding glycerol and chitosan plasticizers. The mixture is heated at a temperature of 70 80 C for 60 minutes. Data from the analysis of Biodegradable plastics products showed that the more glycerol and starch added, the greater the tensile strength and the percentage of elongation. Bioplastics produced From the data, it can be seen that 1.2 grams of chitosan has the best water resistance compared to the others, which is valued at 78.02%. This is due to the hydrophobic nature of chitosan and insoluble in water. So, the greater the chitosan concentration, the greater the % water resistance and the better the plastic resistance to water.

Additive Manufacturing (AM) is a breakthrough in manufacturing technology based on a layer by the layer printing process through various raw material input techniques. Objects to be printed using a 3D model design by adding raw materials to a 3D printing machine are opposite to subtractive manufacturing types, such as in a CNC milling machine. The purpose of this study was to obtain optimal parameters on the DLP type 3D printing machine for product roughness values using methods that include literature, design, and experimental studies. The specimens tested were 30x15x4 mm in size, with ultraviolet resin material. The test results were analyzed based on the 2-level factorial experimental design type and the 3FI design model, which was processed using the Anova method. The analysis results show that the optimal parameter for the DLP type 3D printing machine for the product surface roughness is the layer height; 0.035 mm, exposure time; 19.542 s, and bottom exposure; 60.679 s with a roughness value of 0.469 μm.

Biocellulose can be made by fermentation of coconut water by Acetobacter xylinum. Microorganism. Several developed countries have been starting to research the use of biocellulose as a bio-cellulose that is easily broken down in the world of plastics or membranes, such as edible films and biocellulose membranes. In this study, the biocellulose produced from fermenting at room temperature for 15 days using nutrient-enriched coconut water was converted into cellulose membranes. The treatments in the fermentation process were variations of sugar (10%, 11%, 12%), variations in nitrogen sources using ammonium sulfate (0.3%, 0.4%, 0.5%) and variations in mineral sources using MgSO4 (0.10 %, 0.11%, 0.12%). The optimum results obtained in the experimental volume of 1 liter were in the condition of 12% sugar media, 0.5% ammonium sulfate and 0.12% MgSO4 where the biocellulose results had a thickness of 1.7 cm, 63.50% yield and 4.41 fiber content. %.

Bark from wood preparation utilized in bark gasifier to produced syngas as primary fuel in lime kiln. The aim of the study is to evaluate the effects of biomass utilization to environment using life cycle Assessment (LCA) method. The “gate to gate” approach was used to evaluate two scenarios of different fuel combination: (1) 75% biomass and (2) 100% MFO as primary fuel in the lime kiln for 1000 kg CaO. Evaluation of environment impact related to each scenario using ISO 14040 (2006) that consist of goal and scope definition, inventory analysis, life cycle impact assessment (LCIA) and interpretation. Result shown used biomass to produce syngas as fuel in lime kiln has impact to global warming 4.25E+01 kqCO 2 /ton CaO.

This research is about the experimental investigation of AISI 4340 turning process using carbide tools with hot machining and dry cutting methods. The workpiece is heated using torch flame gas. Experimental analysis is held at various machining conditions for hot machining and dry cutting methods by focusing on the measuring specific cutting energy. The calculation of specific cutting energy is carried out theoretically. The purpose of this research is to observe the effect of various machining process conditions of the workpiece on specific cutting energy of the workpiece. This research also analyzed the effect of specific cutting energy on the surface roughness of the workpiece based on machining parameters after machining. The results showed that the feeding rate was the most influencing factor in determining the value of surface roughness and specific cutting energy. Based on the comparison between hot machining and dry cutting, hot machining provides a lower value of specific cutting energy than dry cutting.

The function of grounding is to neutralize disturbances that occur in electric voltages such as short circuits and leakage currents in equipment. So the grounding system that already used will be able to drain the disturbance that occurs due to leakage currents or short circuits to the grounding terminal and then delivered again to the conduit or conductor and then delivered again to the grounding pole or electrode, then the electrode will neutralize it to the ground. In regard to this point, the grounding system is expected to minimize damage to equipment due to interference with electrical voltage. The smaller the grounding resistance value, the better the grounding system. The results of the analysis show that the value of grounding resistance will be smaller if the depth of planting, the number of electrodes planted, and the planting distance are increased. The Tomat feeder distribution substation itself still has grounding values that are not in accordance with the PUIL standard, article 3.13.2.10. This is due to the lack of moisture in the soil.
