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

Image tampering is one part of the field of image editing or manipulation that changes certain parts of the graphic content of a given image. There are several techniques commonly used for image tampering, such as splicing, copy-move, retouching, etc. Splicing is a type of image tampering technique that combines two different images, replacing particular objects, skewing, rotation, etc. This study applies the splicing technique to image tampering using morphological operations.  Morphology is a collection of image processing operations that process images based on their shape. The aim of this study is to replace particular objects in an original image with other objects that are similar to another selected image.  In this study, we try to replace the ball object in the original image with another ball object from another image

Abstract

One of the fish species that can live in high salinity (euryhaline) is tilapia (Oreochromis niloticus). It is not surprising that tilapia can be found in brackish water, swamps, reservoirs, lakes and rivers. The growth rate of tilapia is influenced by age and water quality as well as the quality and quantity of feed given. The definition of growth is the increase in weight and also the length of the body of living things during a certain period of time. These parameters should be monitored for the survival of the fish. The use of Internet of Things (IoT) can be used as a monitoring and automation system for fish environmental parameters. IoT in this research was chosen because this system can simplify human work. The instruments needed in designing the monitoring system include components that function as the main controller, namely the Node MCU ESP2866 microcontroller, components for detecting water pH levels, namely a pH meter sensor type pH-4502C, and a water temperature measuring component, namely DS18B20. NodeMCU is the main component as a microcontroller as well as a component that connects to Wi-Fi. This system displays the temperature and pH of the water on the LCD and is sent to the android application. The results of the design of the temperature and pH monitoring tool obtained the average error value on temperature readings is 0.88%. The small error value gives the conclusion that the temperature sensor readings in this study are accurate. The pH acidity reading has an average error value of 0.42%. The small error value gives the conclusion that the pH sensor readings in this study are accurate. With the results of sensor value readings and errors, it can be concluded that the tool can be used and can work properly.

Abstract

The capital market is a place for individuals or business entities to carry out investment activities, especially in the banking sector, one of the sectors in the LQ45 stock index which is in great demand by investors in Indonesia. In the capital market, one of the investments that can be made is stock investment, but investors will be faced with uncertainty by fluctuations in stock prices caused by several factors, one of which is macroeconomic factors. Therefore, a predictive analysis of stock prices is needed to prevent uncertainty and minimize losses. Accurate prediction models can use deep learning algorithm methods. In the prediction of stock price movements, the data used is historical data on stock prices which is time series type data. This study conducted stock price predictions using the Bidirectional Long Short-Term Memory (biLSTM) method. biLSTM is another variation of the LSTM model. The object of this study uses the variables open, close, adj close, low, high, volume, value, buying rate, selling rate. The data that has been obtained will be preprocessing. Next build a prediction model using hyperparameter tuning with Genetic Algorithm (GA), train the model and evaluate the model. Data testing was carried out using Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE) with 4 data from the banking sector in Indonesia including Bank BRI, Bank BNI, Bank BCA, and Bank Mandiri. Based on the data testing that has been carried out, the results of the biLSTM algorithm can predict stock prices accurately because it has a relatively low RMSE value with a MAPE value below 10%.

Abstract

A fuel Station or commonly abbreviated as a gas station, is a place to refuel motor vehicles. At gas stations, there are submersion tanks to store oil reserves. In checking, it is still used manual method. The manual method that is still carried out today is considered less efficient in terms of time and accuracy of measuring instrument readings. Moreover, nowadays, it is possible to create digital measuring instruments. In this study, a digital measuring instrument will be designed using raspberry pi. In this study, a prototype of a tubular gas station submersion tank will be made. The measuring instrument consists of raspberry pi as the main processor of the system, using HCSR04-type ultrasonic sensor and LCD as the result viewer. From the research that has been made, a prototype of a submersion tank with dimensions of 60 cm long and 30 cm in diameter has been made. Volume analyzers are able to read with an error percentage of 0.9% in horizontal tube testing and 0.6% in vertical tube testing. The prototype of the gas station submersion tank as an oil container was successfully made and measured in volume by a digital measuring instrument using raspberry pi.

Abstract

Effectiveness is a condition that shows the level of success or achievement of goals measured by quality, quantity, and time in accordance with what has been planned before. The temperature sensor measures the amount of hot / cold energy produced by the object so that it is possible to know or detect the symptoms of temperature changes in the form of analog or digital outputs. A humidity sensor is a measuring instrument to assist in the process of measuring or defining the humidity of water vapor contained in the air. This study used three categories of low price, standard, and expensive. The sensors used are temperature and humidity sensors, namely DHT11, DHT21, and DHT22 which are tested at three different times namely morning, afternoon, and night outdoors, as well as in extreme hot temperature conditions using irons and extreme cold temperature conditions using ice cubes inserted into containers.  This study used a thermohygrometer as a comparison to determine the accuracy of the sensor. After taking data at three different times, namely morning, afternoon, and night outdoors and in extreme hot temperature conditions using irons and extreme cold conditions using ice cubes 30 times, the results obtained were DHT22 sensors with expensive categories whose effectiveness was better than DHT11 sensors and DHT21 sensors. Data from DHT11 morning difference in average temperature (T) = 0.70°C and humidity (H) = 20%, day 1.2°C and 10%, and night 0.70°C and 22%, as well as extreme heat 2.50°C and 4% and extreme cold temperatures average 0.50°C and 15%.
