Abstract

The increase in population causes the level of basic needs to increase, one of which is in terms of food. Where mostly, the food industry uses petroleum-based plastic packaging, the use of these materials can contaminate food due to the nature of the chemical substances that are easily mixed with the packaged products. Therefore, it is necessary to have packaging technology that is safe and does not damage the environment, for example edible film (McHugh and Krochta 1994). The process of making edible films is carried out by mixing the independent variables, namely the concentration of CaCO3, gelatin, coconut oil, and glycerol and then testing the product in the form of tensile strength, elongation, water vapor transmission rate, and thickness. The first objective of this study is to determine the effect of each independent variable on tensile strength, elongation, water vapor transmission rate, thickness, biodegradation, and the number of microbes. Second, obtaining the optimum composition through RSM. The optimum results obtained from RSM resulted in the composition of each variable and response, namely gelatin 7 grams, CaCO3 0.8 grams, coconut oil 3 ml, and glycerol 2 ml and resulted in a minimum thickness response of 0.1 mm, minimum water vapor transmission rate of 1 g.m2 /day, maximum tensile strength of 86 kgf/cm2 , and maximum elongation of 43%.

Abstract

Excessive vibration in a system occurs when the force acting on a system is close to the natural frequency of the system. This vibration can be reduced by adding a dynamic vibration absorber (DVA) to the system. Several researchers have done a lot of research related to DVA and dual DVA (DDVA) placement in the main system. In this research, we conducted a study of the effect of DDVA-dependent addition on translational and rotational vibration responses in the 2-dof main system. This research was started by building a prototype of a 2 DOF vibration system without DDVA and with DDVA. From the prototype, equations of motion and block simulations were then made to determine changes in vibration characteristics that occur in the main system. From the research results it was found that the placement of the DDVA-dependent cantilever absorber at the end of the system with rI 1/10 was able to reduce the vibration of the main system with a percentage reduction at a frequency of 12.78 Hz of 94.1681% for the translation direction and 15.3878% for the rotation direction. Changes in the distance ratio and the inertia ratio of the absorber mass do not affect the DDVA-dependent ability to reduce vibrations in the translation direction.

Abstract

Heat Treament process has experiencing progress driven by improvements in science and technology. The heat treatment process has the aim to form the properties of metals with different work to be achieved in accordance with the objectives being made, heat treatment can also be used to change certain useful properties or for specific purposes for manufacture, such as: escalating machine ability characteristic, restoring the elasticity after cold work operations. The Purpose of the study to determine the effect of carbon equivalent and viscosity of cooling oil on the microstructure and hardness of steel in the hardening process. The method of the study is by doing a hardening process on the specimen with the temperature according to the thickness and composition of specimen. Then the cooling process is done using SAE 10 oil, SAE 40 oil, and SAE 90 oil. Then micro photo testing and hardness test are done with Vickers. The results of the study are, the carbon equivalent equivalent to violence results in a carbon equivalent value that has a significant effect on response because the P-value is smaller than alpha (P-value <α). On the influence of the cool oil viscosity to the hardness, the oil viscosity results have a significant effect on the response because the P-value is smaller than alpha (P-value <α). Whereas the interaction between variations in carbon equivalent and the viscosity of the coolant oil does not significantly influence the response because the P-value is greater than alpha (P-value> α). For the highest average hardness value on VCN 150 using SAE 10 oil at 486.5 HV and the lowest using SAE 40 oil at 450.7 HV, while on S45C steel the highest hardness using SAE 10 oil at 276.5 HV and the lowest hardness using SAE 40 oil is 249.7 HV. In the analysis of micro carbon equivalent structure and oil viscosity which has the highest average hardness value because it has a dominant martensitic structure. Whereas specimens that have ferrite structure still dominate compared to martensite which have the lowest mean hardness value.

Abstract

The effect of anodic oxidation (or anodizing) voltages on the color and corrosion resistance of pure titanium was studied. In this experiment, a commercially-pure titanium was used. To create an "illusion of color," anodizing process modified the oxide layer on the surface of titanium. Because of an interference effect similar to that of a prism, the titanium oxide layer gives the perception of color. Light reflects at different angles from the oxide layer and the underlying titanium, and these reflections interfere with each other. Certain wavelengths of light cancel or merge, resulting in the perception of color from the remaining light. It was concluded that when we use a higher voltage to anodize the titanium, the corrosion rate will increase. It was observed that using 10V gives us the most optimum resistance. For surface roughness, using 40V in both KOH and DAP solutions give us the highest roughness data. Due to the high amount of voltage used in anodizing the titanium, the coating got thicker in the surface and it affects the roughness. The data have shown that the corrosion rate and surface roughness were inversely proportional.

Abstract

This study discusses the cooling of water with a system of spraying it into the free air. The energy source to drive the pump uses energy from sunlight. This research is to solve a problem in an area where it is difficult to get water so that the water for the cooling process must be cooled so that it can be used for the next process. The second problem is that the electrical energy is very minimal, so you have to use other energy that can be used for the cooling process. The process of cooling the water spray system into the air was chosen to solve this problem. The tools used in this study were a 600 Wp solar cell, a 300 W water pump and a spray pipe. The research was conducted during the dry season in August. The research results show that the temperature of the water in the pool is not homogeneous the deeper the water in the pool the lower the temperature. The higher the pool water temperature, the longer the cooling time will be. The greater the pump discharge, the faster it will take to cool the pool water. Solar energy is able to supply energy to drive pumps with pool water temperatures up to 45 C. This cooling system can be used at night because it is equipped with batteries. The results of this research can be used and developed to create a larger system. This cooling system does not cause any impact on the environment because the energy source is from sunlight which is environmentally friendly.

Abstract

Car performance is getting better and better over time. This is thanks to developments in engineering technology. Starting from conventional systems to VVTI technology. What you get is great power with very economical fuel consumption (high efficiency). Even more important is good exhaust emissions. All of this is simply managed by a tool called the ECU (Electronic Computerized Unit). However, this large power output cannot be used properly by a vehicle if it is not equipped with a good chassis system and power scanning system. For this reason, this research will look for/obtain a good chassis system that can match the good engine system to date. The objectives of this research are 1. Is there a big influence of the tensile force of the return lining spring and the stroke of the brake lining on speed acceleration. 2. Look for the right pulling force of the cotton turning spring and the right lining strokes to produce high speed acceleration. The method used in this research is experimental. Meanwhile, the material used is a type of brake lining that is available on the market and is marked with strokes. The reversing spring is set to the desired tensile force. And the research data will be processed using Minitab software. The research results show that: . 1. Scratches on the surface of the brake lining have a big influence on the release of the brake lining from the brake drum wall. By periodically applying strokes to the surface of the canvas, it will increase/maintain vehicle acceleration. 2. The pressure of the brake lining return spring affects the release of the drum brake lining. However, the greater the spring pressure, the more the vehicle's acceleration decreases. 3. Maximum scratches on the drum brake lining surface are 1 (mm). Keywords: Drum Brakes, Spring Style, Drum Brake Pads, Speed ​​Acceleration,

Abstract

This study delves into the optimization of polypropylene cutting board production through injection molding. Polypropylene, derived from propylene monomers, serves as the primary material. The injection molding process often leads to flash defects due to inadequate temperature and pressure settings. The research aims to discern the individual and interactive effects of temperature and injection pressure on the weight and surface area of the cutting boards. Experimental variations encompass temperature levels of 165°C to 175°C and injection pressures ranging from 25 Psi to 35 Psi. Data collection employs experimental methods, and analysis utilizes factorial and RSM approaches. Findings reveal that the lightest cutting boards result from the lowest temperature (165°C) and injection pressure (25 Psi), with an average weight of 105.6009 grams and a surface area of 21,158.3333 mm². In conclusion, both temperature and injection pressure significantly influence the weight and surface area of polypropylene cutting boards, providing valuable insights for enhanced manufacturing processes.

Abstract

Alternative energy is energy that is widely developed by scientists nowadays, especially in terms of electricity. Currently, the alternative energies that are widely developed are wind power, hydropower, geothermal energy, and solar power. Solar power is a promising energy source in Indonesia. The utilization of solar energy requires photovoltaics to convert solar energy into electricity, while for charging a12V/7Ah battery, a buck-boost converter is used. However, the use of the buck-boost converter still has some shortcomings, such as reversed voltage polarity. To address this issue, it is proposed to use a2-switch buck-boost converter. With the2-switch buck-boost converter, it is capable of charging the battery with an initial voltage of19V, which is then reduced to14.25V to charge the battery with an initial voltage of10.08V to11.16V within60 minutes, maintaining the same polarity as the initial input and with a maximum current from the photovoltaic of3.48A. In this thesis, Atmega16 is used to control the2-switch buck-boost converter and a50Wp photovoltaic with a maximum voltage of 21V and a current of 3.48A..
