Abstract

This study delves into the impact of MinMax normalization on Oriented FAST and Rotated BRIEF (ORB) data when utilized as input for an Artificial Neural Network (ANN). The primary objective is to compare the accuracy of an ANN model using two distinct types of input data: raw ORB data and MinMax-normalized ORB data. The results underscore the pivotal role played by MinMax normalization in significantly enhancing the performance of the ANN model. Through a series of comprehensive experiments, it becomes evident that MinMax-normalized ORB data consistently outperforms raw ORB data in terms of accuracy. Impressively, the highest accuracy attained through MinMax normalization reaches 76.6%, whereas the utilization of raw ORB data yields a maximum accuracy of merely 51.1%. This noteworthy improvement effectively validates the prowess of MinMax normalization in counteracting the adverse effects stemming from varied scales within raw data. As a result, the ANN benefits from improved pattern recognition capabilities and heightened predictive accuracy.

Abstract

Solar energy as a non-fossil alternative energy source has become the best choice to overcome the problem of energy demand in most countries in the world. There are two different techniques to convert solar energy: photovoltaic (PV) panels to produce electricity and thermal collectors to generate heat. The two technologies can be combined to provide electrical and thermal energy either simultaneously or separately. In order to optimize the performance of a hybrid photovoltaic-thermal (PVT) solar air heater, it is necessary to collect experimental data on solar irradiation and temperature. This paper emphasized the development of a PVT energy system for hot air production in a temperature range of 50-55 °C. Additionally, experiments were constructed to monitor the information acquired from the proposed PVT solar air heater and the environment, such as hot air temperature, ambient temperature, and solar irradiation. The real-time monitoring system was set for five sample days. A microcontroller unit was used to control the hot air temperature and save the measurement data into memory. The experimental results showed that the proposed PVT solar air heater is capable of maintaining a certain level of hot air temperature throughout the day and night.

Abstract

Pada awal tahun 2019 terjadi pandemi COVID 19 di Wuhan China kemudian menyebar ke seluruh dunia termasuk di Indonesia. Setiap unit kerja mengimplementasikan protokol penanganan COVID 19 dengan mencuci tangan menggunakan hand sanitizer. Hanya saja penggunaan hand sanitizer masih manual dengan disentuh dan digunakan secara bergantian. Oleh karena itu dibutuhkan sebuah rancangan hand sanitizer yang dapat bekerja secara otomatis tanpa perlu disentuh untuk memutus mata rantai penyebaran COVID 19.                               Dari pemikiran tersebut maka penulis merancang suatu sistem hand sanitizer otomatis yang bisa menyemprotkan cairan hand sanitizer tanpa harus disentuh. Sistem ini menggunakan komponen Arduino Nano, sensor infrared dan sensor suhu. Pada sistem ini terdapat dua mode pilihan operasi yaitu mode normal dan mode auto cut off. Pada mode normal sistem akan aktif mengeluarkan cairan hand sanitizer tanpa henti selama sensor infrared membaca ada halangan. Sedangkan pada mode auto cut off sistem akan aktif mengeluarkan cairan hand sanitizer dengan perwaktuan yang telah ditentukan yaitu selama 2 detik lalu berhenti meskipun sensor infrared masih membaca ada halangan. Variabel yang digunakan pada sistem adalah variabel jarak dan suhu. Pada sistem ini relay dan pompa air diafragma digunakan sebagai aktuator.                               Hasil dari penelitian ini menunjukkan bahwa sistem hand sanitizer otomatis dapat aktif tanpa disentuh dengan galat 0 %, membaca suhu pada tangan pengguna hand sanitizer dengan rata "“ rata nilai galat sebesar 0,16 oC dan persentase galat sebesar 0,44 %., menghitung jumlah pengguna alat dengan galat 0,13 orang dan persentase galat sebesar 0,88% dan sistem bekerja dengan baik sesuai dengan mode yang dipilih serta dapat mengeluarkan cairan hand sanitizer dalam bentuk spray.

Abstract

Body Mass Index (BMI) is a parameter often used to evaluate the health status based on someone"™s height and weight ratio. However, the current existing BMI measurement and calculation are done manually. This research aims to develop an automatic BMI measuring tool called Obesity Meter (OBEmeter), by displaying the BMI score and body weight status. OBEMeter utilizes two sensors, namely ultrasonic (HC-SR04) to measure body height and load cell (HX711) to measure body weight. The use of ultrasonic sensors (HCSR04) and load cells (HX711) provides consistent height and weight measurements under various user conditions compared to other types of sensors. The height and weight data are then processed by Arduino in which the BMI calculation algorithm is already embedded. The BMI value is then converted into five-level body weight statuses, i.e. "ceking (underweight), kurus (slim), normal, kelebihan (overweight), and obese". This instrument is equipped with buzzer as an indicator if the BMI value is within the obese category. Our approach improves the measurement and calculation process by performing body and height measurement, then displaying the BMI in very short time automatically. Experimental results show that the reading accuracy of the ultrasonic sensor and load cell sensor are above 95%. Then, test results on 15 users show that the OBEmeter can produce the BMI measurement with 95,79% accuracy, which indicates that it can be utilized as a self-assist device to monitor the user"™s health status practically.

Abstract

Water quality is an important factor in supporting the life of living creatures, one of which is fish. Failure to maintain water quality can result in slower fish growth and can cause mass death. In the process of monitoring water quality, several environmental value are detected, namely water pH, water turbidity and water temperature. With the Internet of Things (IoT), monitoring water quality can be done using the Arduino Cloud application via a smartphone or computer anywhere in real time. These two parameters are given thresholds, the environmental water temperature threshold is between 28 - 30 °C and the water turbidity threshold is between 5 - 50 NTU. If one of the values exceeds the threshold, where the water temperature is higher than 30 °C or below 28 °C, the water turbidity is higher than 50 NTU or below 5 NTU, then a water change will occur as water quality control which starts with draining the water using a solenoid valve, then filling the water using a water pump. The measurement results showed that fish growth for 2 weeks was 17% with maintained water quality and the average percentage of error obtained in water temperature measurements was 0.314% and water turbidity was 2.769%.

Abstract

Paddy drying is an activity to remove the excess of water content within paddy to achieve a better rice quality during the grinding process. Farmers often determine water level based on experience, such as biting the rice, if the skin breaks, it means the rice is ready to be grinded. This research examines a monitoring system on a paddy drying machine in order to obtain a higher quality paddy to be made into rice. On the machine, there is a hearing element to raise the temperature of the drying tank. The rise of the temperature of the drying tank must be monitored to maintain that the temperature is always within the pre-determined threshold. The monitoring system uses DHT11 and SEN0308 sensors connected to ESP32 module as data processing center, before being displayed on an LCD indicator or a smart phone. Accuracy Test results for sensors show both sensor readings are above 90%. The temperature and water level data of the paddy during the drying process can be seen live on an LCD indicator or a smart phone as an accurate information.
