Abstract

Mocaf (Modified Cassava Flour) is flour from cassava which is fermented by lactic acid bacteria. The growth temperature for lactic acid bacteria is 30°C-37°C with a fermentation time of 12-24 hours. In previous research, during 24 hours of fermentation at 33°C, mocaf flour produced the highest protein content of 12.87% without using a temperature stabilization system. The success of the fermentation process is indicated by a decrease in the pH value of the fermentation water to 4.5–5.0. In household scale producers, mocaf fermentation is still carried out traditionally at unstable temperatures. Therefore, a system is needed to monitor and control temperature automatically. In this research, the system that has been designed uses an ESP32 microcontroller as the system control center. The pH sensor is used to detect the pH value of water, the gas sensor is used to detect carbon dioxide gas (CO2) and the temperature sensor is used to detect the water temperature value. Peltier elements are used to lower the temperature and heaters are used to increase the temperature of the fermented water. In this research, a successful fermentation process with a pH value of around 5.0 could be achieved within ±12 hours at a temperature of 33°C, ±18 hours at a temperature of 43°C, and ±25 hours at a temperature of 23°C. In this study the mocaf fermentation process was completed in only ± 12 hours at a temperature of 33°C which is the ideal temperature for the growth of lactic acid bacteria.

Abstract

Visually impaired individuals often face difficulties in performing daily activities due to their limited visual senses. In order for the visually impaired to navigate without collision, a device with a system to detect obstacles in its surroundings is needed. In this study, a assistive cane has been designed that utilizes a fuzzy system based on the Mamdani model to detect obstacles. The main controller is an ESP32, equipped with two LiDAR VL53L1X sensors as inputs, capable of detecting obstacles up to 4 meters away. Family members can monitor the position of the visually impaired cane integrated with GPS through an Android application. The results of this study obtained an average error rate on the reading of two LiDAR Time of Flight Sensor devices with the VL53L1X type against obstacles in front of the stick of 0.00136% and sensor one has an accuracy of 99.85925% and sensor two has an accuracy of 99.862175% against the distance of obstacles in front of the stick. The blind cane made has an average battery life of 1 hour 35 minutes 83 seconds for random navigation, namely there are obstacles and no obstacles in front of the stick. Overall, the system can run well. The blind cane can classify the level of obstacles in front with the category of close at a distance of 0 - 100 cm, medium 101 - 150 cm, and far 150 - 400 cm

Abstract

Compensation is an activity carried out by students outside class hours as a sanction for the student's absence from attending scheduled lectures. In this era, information is really needed, especially information on compensation in lectures. Initially compensation on digital telecommunications networks was still done manually or by coming directly to the admin to ask about compensation. But after this system is created, it will improve the compensation system on digital telecommunications networks. Students only need to access the website and no longer need to come to campus to find out information about compensation. The website has been designed in such a way to make things easier for students. This system is very useful for students because all compensation matters can be done via the website so it will be more effective for students. The problem with the Digital Telecommunication Network Study Program is that 84% of students have not compensated and only 16% of students have compensated. Based on these problems, development was carried out in the form of designing a web-based compensation information and registration system using biometric fingerprints for sending compensation agreements using a telegram bot. The information system used is a series of biometric systems with fingerprint sensor devices with FPM10A module, Telegram Bot, Arduino and ESP32 features and produces a system prototype that can provide information about compensation and compensation registration to polynema students so that it can make things easier for students of the Digital Telecommunication Network Study Program Malang State Polytechnic in paying compensation

Abstract

In office buildings, control of electrical devices is still carried out manually using a switch, namely by turning off and turning on electrical devices directly or manually, the result is inefficient and ineffective. To overcome this problem, it is necessary to develop so that electrical control can be carried out automatically and more broadly at the same time can be monitored via a cellphone by utilizing Internet of Things technology. In this study, the implementation of the Internet of Things made in this smart building includes a gate control system using an ultrasonic distance sensor, monitoring light intensity using an LDR light sensor and the condition of the lights in front of the building's terrace, monitoring movement in the room using a PIR motion sensor for control.  The use of this technology also covers the field of building security by using fingerprint sensors for office employees. Tests in this study used LDR light sensors which produced a small average error of 0.062%, ultrasonic sensors which produced a percentage of success values of 50% on ultrasonic sensors outside the building, and 70% on ultrasonic sensors in the building area. In testing the PIR motion sensor can detect up to 51 cm which is more than enough to detect movement within the building area.  As well as a fingerprint sensor that can be read with a delay of 6 seconds to read fingerprints, update fingerprint sensor data to the database and relay.

Abstract

Painting is an art form that should be preserved. Raden Saleh, Affandi, Hendra Gunawan, and Nyoman Gunarsa's paintings are among those of outstanding artistic worth. The existence of paintings may be jeopardized if the painting protection system is poor. Several well-known examples of art theft include the theft of Affandi's paintings in 1973 and Raden Saleh's paintings in 2007. Apart from famous paintings, personal paintings, which are equally expensive, are frequently stolen. This, of course, concerns the general public, particularly private art collectors with minimal security. Based on these problems, specific management is needed through the "SI LUKAS" Painting Security System. Using the TensorFlow-Based Object Detection Method, a system innovation that can continuously monitor the whereabouts of artworks and send notifications via Telegram, can be accessed from anywhere and at any time using TensorFlow. Based on evaluating the system's delay in reading items at a distance, it is discovered that the system can detect all objects, specifically hands and paintings, within a distance of 50cm to 550cm, however the latency varies. The average accuracy of object detection from various angles was found to be 89.6% for hand objects and 96.4% for painting objects, placing them in the very high category. In other words, the SI LUKAS system is implementable.

Abstract

Koi fish farming is a popular practice in Blitar Regency. Larger ponds are required for cultivating Koi fish seeds, and it is common to use areas such as rice fields for these ponds. However, monitoring water quality in Koi ponds can be challenging, especially during unpredictable weather conditions. To address these difficulties, a study was conducted to develop an early warning system using the ESP32 DEVKIT V1 Module. The system provides real-time monitoring of Koi Pond water quality data through the Telegram app, using sensors to measure temperature, pH, and TDS levels. The data is then transmitted to the Telegram app for display. If the parameters differ from the standard values, the system triggers audio alerts, notifications, and a red LED indicator in the app. The test results show that the system performs well, with maximum recorded values of 31°C for temperature, 306 ppm for TDS, and a pH level of 9.4. The calibration errors for the system are measured at 0.37% for temperature, 0.77% for TDS, and 1.03% for pH. Overall, the system is effective in detecting poor water quality, offering automated alerts and manual control through the Telegram bot

Abstract

Waste bank systems such as Bank Sampah Mentari (BSM), located in Prupuh, Panceng, Gresik Regency, were created as a method of reducing waste. In its operation, the BSM management still has several difficulties such as the need to check the resident’s shelters, to administrative problems that are still done manually. Based on these problems, the implementation of a wireless sensor network on a smart trash bin using LoRa with the AES128 algorithm was made. The way it works is that the node device sends sensor reading data to the gateway every hour. The gateway will describe the incoming data, then upload it to MySQL and firebase before being accessed in the application. The test shows that the system can run well according to the plan where the farthest distance of LoRa is 300 meters. The average RSSI generated by node 1 is -95.78 dBm, node 2 is -112.57 dBm, and node 3 is -117 dBm. HC-SR04 ultrasonic sensor testing has an error of 0.795% (accuracy of 99.205%), while the MAX17048 sensor has an error of 0.3% with accuracy of 99.7%.
