Abstract

Honey is a food substance that has sweet taste and thick structure produced by bees. Honey can be distinguished by observing the color and clarity of honey, but it is quite difficult due to lack of knowledge and each type of honey has almost the same color and level of clarity. Based on these problems, this study designed a system to classify the type and authenticity of honey. The sensors used are the TCS3200 sensor, the LDR sensor, and the pH sensor. The TCS3200 sensor and LDR sensor are placed on the back side and on the front side of the sample glass an LED light is added, while the pH sensor is at the top of the glass and the pH sensor eye is immersed in the solution in an upright position so that the sensor can optimally determine each characteristic of the honey sample. The backpropagation ANN algorithm in this study is processed using Arduino Nano with a network structure of 3 inputs, 1 hidden layer containing 24 perceptrons, and 1 output which is divided into 6 classes. The structure design process uses 900 datasets, the learning rate is 0.001, the epochs are 28.451 and the training process is 2 hours 23 minutes 14 seconds. From the testing process the backpropagation neural network algorithm is proven to be able to classify each honey class well and the NN algorithm accuracy reaches 94.45%, with an average computation time of 0.80076 seconds.

Abstract

Kupang is one of the cities experiencing the impact of water shortages in Indonesia. This problem has arisen for many years because water sources in the city are pretty limited. Therefore, many from the private sector are developing clean water service businesses by utilizing underground water (bore well water with a depth of > 80 m) distributed to households using water tankers. However, bore healthy water entrepreneurs have difficulty selling their water to water tank car owners. This is because most of the people of Kupang City do not know about the existence of a water tank car taken from several borehole waters in Kupang City. In addition, from a customer perspective, it is also challenging to get clean water. The application design for ordering water tanks in the city of Kupang is carried out using an approach, namely the Human-Centered Design method. This method is very appropriate in this study because it is directly centered on the user. The application is in the form of mobile using the operating system in the form of Android. At the testing stage, it was carried out using the usability testing method on ten respondents with a background of being tank water customers in Kupang City. Furthermore, the usability value in the effectiveness aspect is 90%, in the efficiency aspect, it is 0.076 goals/sec, and finally in the user satisfaction aspect it is 82 which is category A. Then, at the last stage, re-evaluation is carried out in order to get the maximum results that the user can accept.

Abstract

Cendol is a traditional West Javanese drink made from hunkwe flour or mung bean flour. Cendol that is often found is green cendol. However, there are also cendol sellers who use red cendol derived from food coloring or agar powder. However, there are still cendol sellers who add synthetic dyes containing Rhodamin B to cendol as a dye. Because the price is relatively cheap and makes the color more striking so that buyers become interested in buying the cendol. Rhodamine B is a synthetic dye in the form of a crystalline powder, green in color, odorless, and fluoresces in a bright red solution. Rhodamine B is very dangerous if consumed and inhaled which can cause liver function disorders, cancer, irritation of the respiratory tract, skin, and eyes. The misuse of these dyes occurs due to a lack of public knowledge about how to distinguish food coloring from Rhodamine B dye and the dangers of its use. Therefore, the researchers designed a system that can classify cendol containing Rhodamine B based on color. The system is built with a portable design for efficiency and portability. This system uses a power bank as a resource, then uses a TCS3200 sensor to determine the RGB value of the cendol color, a 16x2 LCD with I2C to display the output and classification results of the system, Arduino uno as a microcontroller to process data and calculate classifications, and an Artificial Neural Network (ANN). as a classification method. This system utilizes 50 sets of training data, 25 sets of test data for the ANN method, and 15 sets of test data for the whole system. Based on the results of the tests carried out, the accuracy of the Artificial Neural Network method was 96.08% with an average computation time of 58 ms and an overall system accuracy of 93.34%.

Abstract

Based on the National Socio-Economic Survey (Susenas) in 2018, there were 30.38 million people with disabilities/14.2 percent of the total population in Indonesia. Persons with disabilities have difficulty operating electronic devices. On this basis, persons with disabilities need tools to operate these devices without physical contact. In addition, physical contact must also be minimized globally due to the COVID-19 pandemic which has spread throughout the world. The solution to this problem is to create a system that can operate electronic devices without making physical contact. This solution can be realized by using Facial Landmark-based head movements to select the display menu at the clinic with the application name "Smart Clinic". The clinic is the main focus because it is the most vulnerable place to the spread of COVID-19. This system works by classifying head movements to the right, left, up, and down. The output of this system is in the form of six menu options. The results obtained from the research accuracy of 90% for the distance of the user as far as 60 cm from the camera, 85% distance of the user as far as 75 cm and 82% distance of the user as far as 90 cm. The distance is selected based on the user's safe viewing distance with the monitor screen, which is in the range of 50-100 cm. This system also has a relatively fast computation time of 0.0034745 s.
