Abstract

Technological advances make it easier to convey information in public places through media. LED displays are one of the information media that is widely used because they are more interesting to look at. This research focuses on the analysis of apparent power usage with variations in letter and number characters and differences in font size that occur in the running text when operated. Voltage and current testing uses analog and digital measuring instruments. The use of DC voltage that has been rectified from the output of the current sensor and voltage sensor is proportional to the current and the voltage is directly proportional to the voltage. Testing was carried out based on number and letter characters with font sizes of 15, 18 and 20 which were turned on for 10 minutes. Based on the research results, it shows that with different font sizes, letter and number characters have greater apparent power and resistance values as the font size increases, where the power value for letter characters is between 51-58 Volt Ampere, while for number characters it is between 49-58 Volt Ampere.

Abstract

Sludge oil is also defined as oil sludge that contains heavy metal compounds with characteristics that are difficult to clean with air. Therefore, oil sludge processing must follow the established B3 Waste Processing regulations. This research aims to provide information on viscosity tests as an initial parameter for B3 waste management methods. This research uses a distillation method using distilled water with a solvent volume ratio of 1:1 and 2:1 and a redwood viscosity test to obtain the viscosity value of the sample. The results of the research show that the effect of temperature on waste viscosity is negative exponential, while the effect of the distillation volume ratio on the viscosity of the sample volume compared to the solvent is that the viscosity value is greater.

Abstract

Corrosion events in daily life present their own problems for an industry. Most corrosion phenomena themselves are electrochemical reactions that occur naturally between metals or metal alloys and the environment. This research aims to determine the corrosion rate of nails using agar media. This research was carried out by calculating the corrosion rate using the weight loss method only due to rusting when the sample was submerged for 36 hours, 72 hours and 108 hours on the corrosion rate of iron nails. Based on research results. From the research it can be concluded that the longer the soaking time, the smaller the rate of corrosion caused by the pack. The corrosion resistance of nails is very good because it is less than 0.02 mm/years. During the immersion period of the iron material in the gelatin medium, the corrosion rate was very good because < 1. The results of the research can be concluded that the longer the soaking time, the smaller the corrosion rate caused by the pack. The corrosion resistance of nails is very good because it is less than 0.02 mm/years. During the immersion period of the iron material in the gelatin medium, the corrosion rate was very good because it was < 1.

Abstract

This paper discusses electric-based vehicle control systems. Electric vehicle charging stations are only capable of charging based on slow, medium, fast, ultra fast charging and are not equipped with an overcharge system. So a control system is proposed for overcharge protection of battery current and voltage. The control system is modified with a half wave rectifier circuit to increase battery power efficiency. Method of modifying a half wave rectifier circuit with IC LM 7812 and capacitor. The results of the circuit modification show that the battery power is 7.96 w, 7.26 w, 6.60 w, 5.94 w, 5.24 w at varying input voltages of 220-200 Vac, and the efficiency is 0.87%-0.86% at an input voltage of 190-180 Vac. Meanwhile, the battery power is 7.96 w at an input voltage of 230 Vac and the efficiency is constant at 0.87%. The application of a control system can increase the efficiency of electricity-based vehicle batteries at a constant input voltage.
