Fabrication prototype of DSSC (Dye-Sensitized Solar Cell) using mulberry powder from mulberry leaf extract (Morus Alba L.) and dragon fruit (Hylocereus Polyrhizus) as photosensitizers has been carried out. The test was carried out by testing the I-V characteristics at a light distance of 10, 20 and 30 cm from the material sample. The test results show that the chlorophyll of mulberry and dragon fruit is capable of producing an electric current which is a characteristic of the resistance of organic materials. In DSSC with mulberry powder dye, the greatest power was found at a halogen lamp distance of 10 cm with a power of 257.77 mW. Whereas in DSSC with red dragon fruit flesh dye, the greatest power was obtained at 162.35 mW with the halogen lamp distance from the DSSC device being 10 cm. DSSC testing using mulberry powder and dragon fruit showed that the power produced on mulberry powder leaves was higher than dragon fruit. The results of the I-V characteristic test on the DSSC device show a linear graph.

A composite is a material formed from the combination of two or more constituent materials through an inhomogeneous mixture. The ironwood waste has less economic value, which makes the authors interested in conducting research using mosquito nets and particle composite ironwood waste. Which is to find out the effect of volume fraction and angle orientation of the fiber composite polyester-ulinwood powder (Eusideroxylon zwageri)-mosquito wire on the bending strength. The bending test was carried out using the ASTM D-790 standard with the three point bending test method and the composite was manufactured using the hand lay-up method with the particle composition: polyester: 10%: 90%, 15%: 85%, 20%: 80%, and 25%: 75%. The results obtained in the comparison of the composition of less ironwood powder, a finer mesh size with an orientation angle of 45°, and mosquito wire show the highest bending strength and high deformation ability (ductile), and the addition of mosquito net as one of the composite specimen fibers of polyester resin does not increase significant bending strength but can reduce the deformability reduction effect.

Bio-oil is a blackish liquid fuel derived from biomass such as corn cobs, rice husks and other biomass such as cocoa shells. The organic acid content in bio-oil gives bio-oil acidic properties. Bio-oil can be obtained in the pyrolysis combustion process, using a combustion tube. The number of tubes used can affect the yield characteristics of bio-oil. The purpose of this study was to determine the characteristics of bio-oil bio-oil produced by varying the number of combustion tubes in the pyrolysis process. Such as pyrolysis time, amount of bio-oil, temperature and content of bio-oil. This research method utilizes cocoa shell biomass waste to turn into bio-oil with a pyrolysis process, namely by varying the number of combustion tubes, namely one tube, two tubes and three tubes with a diameter of one tube 27.74 cm, two tubes 19.6 cm and three tubes 16 cm with the same cylinder volume of 18.7 cm3, by carrying out the prolysis process, namely putting the cocoa shell waste into the combustion tube and closing it. Then the combustion tube is inserted into the pyrolysis reactor and then closed and then burned. From the results of the research, the results of bio-oil in a single tube of raw material were 130 ml with a processing time of 113 minutes and bio-oil characteristics, a calorific value of 2177,464 cal/g, a viscosity of 1,574 CPs, and a pH of 4.77. Whereas in the second raw material tube, there were 80 ml with a processing time of 105 minutes and specifications for bio-oil, a calorific value of 2071,151 cal/g, a viscosity of 1,780 CPs and a pH of 4.96. While the three raw material tubes were 50 ml with a processing time of 100 minutes, and bio-oil specifications, calorific value 1983,950 cal/g, viscosity 2,626 CPs and pH 5.42.

Mg is a light metal that has superior properties, including low density, good ductility, medium strength, and good corrosion resistance, mg can also be combined to obtain better properties. Interest in the application of MgAZ31B for bone replacement has now become a major topic and continues to be intensified to improve results that are more compatible with bone constituents found in humans. In the human body, there are approximately 206 bones in an adult. Calcium, magnesium, and phosphorus are the main elements in the formation of human bones but there are many other elements in their formation, the real bone matrix is made of protein, collagen, calcium phosphate, calcium carbonate, magnesium salts, and other minerals. When viewed from the element of bone magnesium is an important part of bone formation and certainly not harmful to the main elements of human bones. However, before being used as bone implants, magnesium must pass the mechanical and clinical test stages.

This research studies the effect of flow rate on the pouring of molten metal into the mould so that the flow rate into the mould can be controlled. Furthermore, this research studies the effect of mould preheating so that the temperature inside the cavity can be maintained, especially for narrow holes. The process starts with making the engine cylinder head pattern and gating system using a three-dimensional printer with polylactic acid resin. The mould pattern and gating system are combined and coated with a layer of cement plaster, silica sand and kaolin. After the coating is dry, the mould is heated until the mould pattern evaporates and there is no residue. The casting process was carried out at pre-heating moulds of 300 0C and 350 0C and a pouring temperature of 800 0C with pouring speeds of 20, 30, and 40 rpm. The final stage of the research is manufacturing test objects and testing mechanical properties. The results showed that the higher the pouring speed, the less perfect the casting results, especially in the cylinder head fins. The best casting results occurred in the pre-heat condition of the 300 0C mould with a pouring speed of 20 rpm, with a Maximum Tensile Strength of 105 N/mm2, Hardness 53 hardness Brinell test (HBN), Density and Porosity of 2.43 gr/cm3. The material used in this study refers to the reference is A356 Aluminum Alloy.

The continuous use of fossil energy will cause fossil energy reserves to be depleted. In the transportation and industrial sectors, the use of fossil energy is the main energy source. This is because the fuel used in transportation and industry still relies on fossil fuels. To overcome the energy crisis in the future due to the exploitation of fossil energy, it is necessary to use alternative energy. One alternative energy that can be used is biodiesel. Biodiesel can be obtained from animal or vegetable fats. Kesambi is a plant that has the potential as a biodiesel feedstock. The kesambi plant can produce oil obtained from the seeds of the kesambi fruit through the pressing process. However, before being used and mass produced, a product testing process is required first. Tests can be carried out using the premix combustion method by varying the equivalent ratio and fuel composition. The fuel used is kesambi biodiesel with the addition of methanol. Testing produces fire characteristics. Flame characteristics yielded data on the relationship between laminer combustion rate and equivalent ratio as well as flame height and fuel composition. The test results show that the highest laminer combustion rate lies in the equivalent ratio 1 of 68,024 cm/s with a fuel composition of B90M10. Then the highest flame height at the equivalent ratio of 1.2 is 25,663 mm with a fuel composition of B100M0.
