Abstract

Reserves of fossil energy sources are starting to run low, so the government has launched renewable energy sources. The National Energy Policy (KEN) targets Indonesia by 2025 to use renewable energy sources of 23% of its energy needs. Because of this, the government has started opening places that have the potential for generating renewable energy, especially the areas where PLN electricity cannot reach, withincluding the southern coastal area of Kebumen.. The wind potential in this coastal area of Java Island meets the criteria for a Wind Power Plant. The purpose of this research was to analyze the wind potential in the southern coastal area of Kebumen. The specific purpose of this study was to determine the wind speed and the location and calculate the power generated by the wind in the southern coastal area of Kebumen to determine the potential of PLTB in Kebumen area. The stages of this research consisted of retrieval of secondary data, analysis using Excel, and power analysis using HOMER. Based on wind speed data from NASA, the southern coastal area of Kebumen is suitable for making PLTB, especially Buayan and Ayah, because the wind speed between 2016-2020 is 2.15 m/s. Then, the power produced annually in these places, based on the HOMER application, was 86.50 kWh/year.

Abstract

The current situation demands the prevention of the spread of the virus, one of which is by wearing a mask and checking the body temperature. This paper serves as a means of detecting the body temperature by using a thermal camera and the mask with a web camera. The camera is the sensor, and a buzzer is an actuator that go off automatically. A mask detection device is a tool that detects visitors who wear masks. It works by detecting the visitor's face using a camera and Open CV or digital image processing. Then, the data will be processed and compared to the one that has been input into the program. This program is able to detect masks and provide warnings if the visitors do not wear masks in a public space. When the body temperature detector detects a visitor of the normal category, which is 36˚C - 37.5˚C, the buzzer does not go off; when the body temperature is higher than 37.5˚C, the buzzer goes off automatically. An error occurred due to the dark conditions, and from the five trials with 100 cm distance, 60% of the trials were successful. Therefore, it was concluded that the testing of the mask detector succeeded with more than 60% success when the lighting was sufficient; and the distance ranged from 100 cm. This system experiment with five experiments on each sample obtained pretty good results. To get good results, the light determination is very influential.

Abstract

This study intended to create a sea wave simulator to find out the potential of ocean wave power plants. To achieve the objective, this study used two systems: generation and reading. Generation used a DC motor as a drive from sea waves, while readings employed an IMU-GY86 sensor for readings of altitude and energy potential generated. The result of this study is that air and air pressure affect the results of measuring the wave height of seawater. Air pressure is inversely proportional to the elevation of a place: the higher the area, the lower the air pressure. The highest potential energy density of seawater waves amounts to 2405.33 J/m2, and the lowest was 550.18 J/m2, with an average value of seawater wave density energy of 1342.41 J/m2.

Abstract

Batik coloring still uses synthetic dyes, so the disposal of coloring waste should not be careless. Most batik craftsmen process their batik waste by settling the waste liquid for a long time. The process is very ineffective. The purpose of this research is to design a batik processing tool that is cheap and effective. The research method uses the electrocoagulation method. The electrocoagulation method is an electrochemical water treatment. The design of this batik waste treatment tool consists of five parts including: (1) Electrocoagulation Tub, (2) Skimmer, (3) Electrode, (4) Sand Filter, and (5) Studge Drying Bed. This tool works with 900 watts of power with an output of 20-40 volts DC. The capacity of liquid waste is 50 liters. Duration of waste treatment for 2 hours. The electrocoagulation method is able to reduce the values of BOD5, COD, TSS, and TDS in batik dye waste. The pH of wastewater which is still high can be reduced by giving alum.

Abstract

Indonesia has the potential of sea wave energy with the second largest coastline having a density of up to 20 kW / m2. Currently, the use of sea wave technology is still at the prototype stage, with several weaknesses such as erratic sea waves, tides and ocean currents so that they can affect the power generated in ocean wave energy. The results of ocean wave energy in mechanical arrays cannot be utilized because of erratic waves. The higher the wave, the greater the power generated and vice versa. If this problem is not resolved, it can cause unstable power output and cause damage to electronic equipment. The solution to this problem is to modify the DC-DC buck boost converter circuit using the Hyeteresis band method, which limits voltage surges below or above to produce the desired voltage in order to maintain constant power and as energy for storage in the storage system. The result of this study is that the performance of DC generators in producing voltage is greatly influenced by speed. At low speeds, the voltage produced by the generator is still too low to charge the battery or in other words cannot be in a perfect charging position, while at maximum speed it produces voltage with Achieve a level sufficient for battery charging. Therefore, control and adjustment of generator speed is key in maximizing battery charging efficiency using a buck-boost converter.
