Abstract

The high yield of coconut in Indonesia is positively related to the production of coconut shell waste which is difficult to decompose by microorganisme. Therefore, in recent years a method of utilizing coconut shell waste for charcoal and liquid smoke has been developed. So far, the process of making liquid smoke from coconut fiber (coconut coir liquid smoke) is usually carried out for 3-5 days and the amount of liquid smoke is very small. The use of liquid smoke is also adapted to clarify the qualities of liquid smoke, is used as a wood preservative and thickener, as an antimicrobial agent, and as a natural food preservative. In addition, e-liquid can also be used as a natural preservative for food, meat, and fish, it is also very suitable to be used as a natural substitute for formalin or borax for insect repellent, and a wood preservative which has received wide attention in recent years. Therefore, the purpose of this research is to design a device that produces liquid smoke from burning coconut shells from the distillation process, which can increase the amount of liquid smoke produced.

Abstract

Glass Fiber Reinforced Polymer, commonly known as GFRP, is that as a train interior component, it must have good mechanical properties. The addition of flame retardant compounds contained in GFRP materials can affect the tensile strength of GFRP materials. In this study, GFRP composed of Alumina Trihydrate (ATH) and Melamine Cyanurate (MCA) powder was mixed into a vinyl ester resin. The method of making GFRP specimens uses the hand lay-up method. GFRP was mixed and tested for material with ASTM D-638 standard tensile test. The results obtained after the addition of 25% ATH, a mixture of 5%, 10%, and 15% MCA at 25% ATH, 25% ATH in the outermost layer, and a mixture of 5% MCA with 25% ATH in the outermost layer to the weight of the resin was a decrease in strength when the percentage of filler powder increases. Tensile strength, strain, and modulus of elasticity of GFRP were optimum at the addition of 25% ATH with 5% MCA to the weight of the resin in the outer layer. The result of tensile strength is 124.37 MPa, strain is 12.76%, and modulus of elasticity is 975.85 MPa. The results show that a mixture of ATH and MCA has a synergistic effect, so that it becomes a recommendation for interior sidewall panels and ceiling panels on trains.

Abstract

Geopolymers are solid inorganic polymers produced from a chemical reaction called geopolymerization between an alkaline solution and an aluminosilicate source. Aluminosilicate materials are composed of silica and alumina atoms. To activate the polymerization reaction between silica (Si) and alumina (Al) an activator solution is needed. Many studies have used geopolymers because they are known for their fire retardant properties. With the added ingredients of Sodium Borax Tetra Hydrate and Diammonium Phosphate, these two added ingredients have the potential to be fire retardants. To determine the effect of the addition of geopolymer additives, pressure testing was carried out on the specimens before and after being burned at 900 oC for 1 hour. In this study, using raw materials metakaolin and silica fume of 80:20 (%) and a constant KOH pellet and water glass activator solution. As well as varying the additives, namely 1% Sodium Borax Tetra Hydrate, 1% Diammonium Phosphate and specimens without additives. The results of the compression test showed that the composition that had the best compressive strength before combustion was the addition of 1% Diammonium Phosphate, which was 24.4 MPa. While the specimens after burning which have the highest compressive strength value are the specimens without additives, namely 9.5 MPa.

Abstract

PT Lintech Duta Pratama is one of the manufacturing companies where in the process there is a finishing and painting manufacturing process. Painting is done with the aim of inhibiting the rate of corrosion and improving product appearance. Improper painting process results in defects. Products that have defects require repair so that they can then be sent to customers. Repeated repair processes cause delays in product delivery. To get products with good quality, research is needed to get the optimal combination of process parameters in the painting process. The process parameters studied are surface roughness, substrate temperature, and abrasive material type. The experimental design uses the taguchi method in the form of an orthogonal matrix L_9(3^4) with three replications. From the experimental results, the optimal combination of process parameters on adhesion and process cost simultaneously on paint adhesion was obtained, namely surface roughness at level 1 with a value of 50, substrate temperature at level 2 with a value of 34°C, and abrasive material type at level 1 with garnet abrasive. The surface roughness parameter gives a percentage contribution of 14.56%, substrate temperature 0.48%, and abrasive material type 84.28%.
