Abstract

Boarding rooms as a place to live should have good air quality. The most common causes of decreased indoor air quality are poor air circulation and contamination from harmful gases, one of which is carbon monoxide (CO) which is commonly found in cigarette smoke and vehicle emissions. Tool developed in this research is expected to reduce the potential dangers that may arise from high concentration of carbon monoxide gas and discomfort due to hot and humid room air. The system is designed to detect ambient air quality using the DHT22 and MQ7 sensors, and uses a fan and exhaust to control air quality. The system is built with a parameter threshold that can be reconfigured. This system is also made using a finite-state machine algorithm to define several states that represent each existing process. One of them is a deep sleep state for power saving, this is needed because the system will operate continuously, the method used is taking advantage of the deep sleep mode on the low power feature of ESP8266 chip. From the test results, it's known that this tool successfully performs its function, and is able to reduce current consumption by 34.82 mA under ideal conditions.

Abstract

Parking is a process for every vehicle that stops at a certain place. Parking areas owned by agencies, institutions, and institutions should prioritize service and security for the sake of parking eligibility. The parking system that has been implemented so far is still being implemented with limited number of human guards, so it has many loopholes for theft to occur without the vehicle owner knowing. RFID technology is a solution for today in solving the problem of theft and contactless technology. Several studies have been conducted, many of which are used only as a parking area monitoring tool. The lack of a system/tool that is usually used to respond when a vehicle is lost belonging to a parking area user is a problem for both the parking area owner and the vehicle owner. This security system is made using RFID technology, Load-Cell sensors, and GSM modules as a solution to related problems. From the manufacture of the system, of course, it is necessary to test the problem of delay or response speed when a theft occurs. The results of the tests and analyzes carried out get pretty good numbers, namely around 2 seconds to provide notification in the form of SMS to vehicle owners, and about 5 seconds for the system to close the portal when it is open. The response given is the result of data transactions from the sensor node to the Gatekeeper node using the ESP-NOW protocol communication. The Gatekeeper node is also used to communicate with the basis data, in terms of verifying whether the user is registered or not. Registered user data will of course be recorded when accessing the parking area when entering or exiting and displayed on a web page.

Abstract

Indonesia is one of the largest fish producing countries in the world. One of the fish that is in demand in Indonesia from various circles of society is catfish. Therefore, the way to increase catfish production is to maintain the quality of pond water used for catfish farming. The quality of water used for catfish farming is very influential on the growth of catfish. Using a monitoring system can help to monitoring the water quality of catfish ponds so that catfish growth can be optimal. In this study, a catfish pond water quality monitoring system was created which consists of three nodes slave and one node master and uses a webserver as an interface. Each node slave has two sensors, a temperature sensor and a pH sensor that functions as a detector of water quality in the pond. Communication between nodes slave and node master uses the BLE communication protocol. while for the webserver to run on the master node using WiFi communication. The microcontroller for this system uses NodeMCU ESP32. Based on the test results, the average system accuracy in reading the water temperature of the catfish pond is 97.88%, the average system accuracy in reading the pH of the pond water is 98.53%. The farthest BLE communication is 25 meters with a delay of 2815.8 ms for BLE communication and 252.4 ms for the webserver.

Abstract

Wireless Sensor Network (WSN) is a technology concept that uses a number of nodes that have processing capabilities to achieve or complete certain tasks. In general, wireless sensor network architecture requires an embedded system or embedded sensor that is able to connect to the network and communicate through the cloud server. One of the devices commonly used in the WSN architecture is the NRF24L01 module which is a communication module based on a single frequency radio wave band. The use of a single frequency for sending and receiving data allows the transmission signal to collide with the receiving signal which causes data packets to be lost or damaged. This can be avoided by using the method of scheduling sending and receiving data. One of the scheduling methods that can be used is the Time Division Duplex (TDD) method. The concept of TDD is to give a time slot at one processing time, where the process of sending and receiving data occurs in the same frequency as each processing time. This process has a time guard that is between the time of sending data and receiving data which functions to prevent collisions between sending and receiving signals. Previous research has succeeded in implementing the TDD method on the system of sending and receiving data using Bluetooth low energy and Wi-Fi in the plant monitoring system. The test of this research is done by testing scenario of sending data based on distance variation with two parameters, namely success ratio and average delay in sending data. The distance variation used in the study is 1 meter to 10 meters. The success ratio parameter produces the lowest success ratio value of 71% at a distance of 7 meters and the highest ratio of 91% at a distance of 5 meters. Then on the average delay parameter, the delay results are 0.871 seconds on sensor node 1, 0.638 seconds on sensor node 2, and 0.644 seconds on sensor node 3.

Abstract

Indonesia, which has a tropical climate, gets sunshine all year round. It is very useful for people to dry household or industrial needs. Examples of industries that use sunlight are the production of crackers, salted fish, coffee, and unhulled rice and others. However, apart from getting the continuous heat of the sun, there is also rain that is present erratically. So leaving things outdoors will be risky, especially during the rainy season. Therefore, the researchers created a sun dry system that can be put outside automatically when the outdoor conditions are sunny and there is no rain, and inserted when the outdoor conditions are rainy or there is no sunlight. These conditions will be taken using a raindrop sensor and a light dependent resistor sensor. Arduino Nano as a microcontroller used to control sensors and actuators. To control the system using the K-Nearest Neighbors method. After testing, obtained good results. The best value of accuracy and computation time in using the K-Nearest Neighbors method is at k=3 with the average accuracy of 98% and the computation time is 37.173 microseconds. When compared with the if-else method, the if-else method has an accuracy value of 100% and a computation time of 13.232 microseconds. The K-Nearest Neighbor method is feasible to implement in this system, but a simple if-else method is more profitable due to better accuracy and simpler source code.

Abstract

The development of computer technology in the Central Processing Unit (CPU) architecture is still accompanied by many innovations. However, the rapid development has a negative impact, namely the difficulty of participating in the creation of the innovation itself. Meanwhile, the creation of innovations must be carried out by various parties in order to create healthy competition in order to achieve common progress. This impact can be minimized from an educational side, namely in the teaching and learning of computer architecture & organization using software in the form of a simulator. The effectiveness of teaching and learning can be further strengthened by practicing directly (hands-on) an architecture on a programmable semiconductor device, namely the Field Programmable Gate Array (FPGA). There are many soft-processors or computer/CPU architectures that can be implemented on FPGA. Altera and Xilinx also have soft-processors that are ready to use but are not suitable for teaching and learning. This study shows another simple computer architecture that can be used for the focus mentioned, namely Simple-As-Possible (SAP), specifically the 2nd generation. In addition to implementing the SAP architecture with some adjustments, this research also designed two additional circuits to provide the capability for programming the CPU. Three units (including SAP) were implemented on the Xilinx Spartan-3E Starter Kit Board FPGA module. FPGA resource usage are 7% slice flip-flop, 24% 4LUT, 30% slices used, 10% IOB, 5% RAM16 and 4% BUFGMUX.

Abstract

Every year, the death rate caused by traffic accidents increases sharply. One of the biggest causes of traffic accidents is drowsiness experienced by vehicle drivers. Therefore, researchers are interested in developing a drowsiness detection system using low power in the hope of reducing the rate of traffic accidents caused by drowsiness. The system is designed using the FC-51 Infrared sensor embedded in the glasses as a detection of the driver's eyelid position. The system is built with a threshold parameter that can be reconfigured such as the duration of closed eyelids. This system is also built using a finite-state machine algorithm, where this algorithm will create several states with different operational modes. One of these states is the Low Power On state to save power. This is necessary because the system will work continuously. In the Low Power On state, the method used to save power usage is to make the 800L SIM module enter sleep mode by slowing down the clock its used. The system will send a notification in the form of a buzzer and an SMS message containing the driver's coordinates to relatives when sleepiness is detected. From the results of the tests that have been carried out, it is concluded that the system can carry out each of its functionalities and succeeded in reducing the use of current consumption by 30% when in the Low Power On state.

Abstract

The Food Court is one of the people's favorite places to find food, drinks, and snacks. But the problem of long lines waiting for orders can lead to problems such as the transmission of the COVID-19 disease and the possibility of a decrease in the number of customers due to not waiting in line. This queuing problem has been overcome by the existing system, the Restaurant Ordering Paging System, but this system has a weakness, namely there is no clarity on the order status. The purpose of this research is to build a new system and tool that has a 1602 LCD feature to display messages from the order status, and also features changing the message content according to user needs. In this system, the Finite State Machine will be used as a method of how the system works to achieve system goals, so that to perform its function, each node in the system needs to move between states according to the state of its objective function. The system obtained from this research is divided into 2 tools, namely the restaurant node and the customer node, with the restaurant node having 4 states, namely the default state, programming mode state, reading user input state, and data sending state. On the other hand, the restaurant node also works with 4 states, namely the default state, LCD blinking state, LCD blinking state with beep buzzer, and state delay for 1 minute. The results obtained from this study are the success of data transmission by 90% from the 4 state tests used, with 2 customer nodes, 1 restaurant node, and the test was repeated 16 times.
