Abstract

Garbage is leftovers or discarded items that are no longer used and are no longer used by their owners. Waste is generally divided into two, namely organic and inorganic waste. Both of these wastes have benefits for us, but they also have an impact on the environment. Organic waste is waste that comes from the remains of living creatures (nature) such as animals, humans, plants that are experiencing decay or weathering. This waste is classified as environmentally friendly waste because it can be broken down by bacteria naturally and quickly. The research object studied in this research is camera detection on a waste detection tool using a camera which aims to detect types of tourism waste, where in this research I will conduct research on the detection of organic and non-organic tourism waste. The waste problem in Indonesia is caused by an increase in waste produced by the community, a lack of rubbish disposal sites (TPS), the spread of insects and rats due to rubbish, as well as environmental pollution through land, water and air pollution. So it is hoped that this tool will be able to reduce the waste problem in Indonesia, especially in the tourism environment. In this study, an average value of 0.83% was obtained, where the results were in accordance with the initial target when starting training and carrying out detection. This makes it possible to move the servo more accurately because the detection results have a high value. From the test results above, an accuracy of 90% was obtained, and the results of the servo movement were in accordance with the detection results, where if the results were organic waste detection, the servo would rotate 90 degrees and if the detection results were non-organic, the servo would not move or remain in the 0 degree position. There was no error in servo accuracy, but the error in detection was 10% from 20 samples which resulted in the servo moving in the direction of the servo movement in the error detection direction.

Abstract

The more face mask products for sensitive facial skin that are created, consumers also feel confused by several considerations such as excessive side effects for the mask products they will use so as not to worsen the condition of the facial skin. Therefore, to help consumers in choosing the right face mask in terms of consideration of benefits, side effects that will be caused, and affordable prices, the authors compiled a study with the title "Selection of Face Mask Products for Sensitive Skin Using the Composite Performance Index (CPI) Method". Composite Performance Index (CPI) was chosen because this method is good at decision making and the calculation process of the CPI method only requires the criteria value of several alternatives which when compared to the CPI method process is shorter. This method can be used to determine the assessment or ranking of various alternatives based on several criteria. Criteria values are inputs that have been entered and converted into numbers. While the alternative value is the weighting obtained from the calculation of multiplication, addition of ingredients or division of each criterion. The result of this research is that the assessment process can be carried out from each mask product using the criteria of price, skin condition, mask benefits and consumer age. The system can determine the best mask for sensitive skin by implementing the Composite Performance Index (CPI) method with the results of the website validity test getting a percentage of 85.34% with a very good interpretation.

Abstract

The Indonesian Dance Robot Contest (KRSTI) is a competition for the manufacture, design, and programming of dance robots with elements of the arts and culture of the dance department, especially the archipelago. The obstacle faced by the robot is when the robot is required to stop according to time on the music but there is a movement that appears when the time has been declared over. The method used is using the RTC module. The DS3231 type RTC module is a circuit that functions to store time and date with accuracy and precision and is integrated with the AT24c32 eeprom serial for other data storage purposes. The results of time research testing on this robot are running well, the first results obtained are that the robot can adjust the time when it runs. Furthermore, at the time of pause the RTC module does not interfere with the running of the robot. Finally, the success rate of the robot stopping at the specified time is 100%, the robot can be tested with time according to the user's wishes.

Abstract

This paper examines the physical, optical, and electrical characteristics of cesium tin-germanium triiodide based single halide Perovskite absorption materials in order to provide the best photovoltaic application. In light of the diversification of the use of natural resources, perovskite solar cells are becoming more and more essential for capturing renewable energy. In this research work, a cesium tin–germanium triiodide (CsSnGeI3) perovskite-based solar cell (PSC) has been reported to achieve a high-power-conversion efficiency (PCE).  CsSnGeI3 perovskite-based solar cell has been proposed for the Pb and toxic-free (Al/FTO/ TiO2/CsSnGeI3/Mo) structure simulated in Solar Cell Capacitance Simulator (SCAPS-1D software. At first aluminum, fluorine-doped tin oxide, Titanium dioxide, cesium tin–germanium triiodide and   Molybdenum have been inserted into SCAPS and simulated using specific temperature. In this simulation, the electron transport layer (ETL) FTO, the buffer layer  TiO2, and the absorber layer  CsSnGeI3 were all used. Utilizing variations in thickness including absorber and buffer, defect density, operating temperature, back contact work function, series and shunt resistances, acceptor density, and donor density, the performance of the proposed photovoltaic devices was quantitatively assessed. Throughout the simulation, the absorber layer thickness was held constant at 1.6 ?m, the buffer layer at 0.05 ?m, and the electron transport layer at 0.5 ?m. A solar cell efficiency of 24.75%, an open-circuit voltage of 0.95 volts, a short-circuit current density of 30.61 mA/cm2, and a fill factor (FF) of 85.42% have all been recorded for the  CsSnGeI3 absorber layer. Our ground-breaking findings unequivocally show that CsSnGeI3-based PSC is a strong contender to quickly overtake other single-junction solar cell technologies as the most effective.

Abstract

River water level monitoring is the process of monitoring water in rivers that sometimes overflow and cause flooding. Residents need to know the water level to serve as an early warning. Therefore, it is necessary to have a measurement mechanism and river water level information in order to provide information to the community. Monitoring river water levels in this research uses the HC-SR04 ultrasonic distance sensor and water level sensor. Arduino Uno is used as a microcontroller. This research uses a prototype with water level measurements observed at 3 cm (low), 3-5 cm (medium), and 5 cm (high). The water level can be monitored from anywhere through Blynk. The implementation of the resulting water level has been successful in accordance with the parameter values on the water level sensor which is marked by the display of numbers on the LED, the color of the lights, and different alarm sounds for each water level. HC-SR04 ultrasonic sensor is able to measure and provide water level data in realtime and from any place using Blynk.
