Abstract

Currently, most motorized vehicle safety technologies, especially cars, still rely heavily on the manufacturer's default safety system from the car system itself. By using a security system from the factory default there are still shortcomings because a motorized vehicle or car can still be used by anyone and there is no age limit in its use. For that, we need a car safety system that is able to prevent the occurrence of car theft and underage drivers. The purpose of this research is to design a central lock security system for motor vehicles, especially cars, using e-KTP identification to improve the security system and reduce underage drivers. For the identification process of e-KTP ID using the RFID reader MFRC522. The RFID reader is connected to the Arduino Nano as a controller. The results of the research used the RFID reader to read e-KTP ID in a vertical and horizontal position with a distance of less than 12 mm. When there is an acrylic barrier and a glass barrier the maximum reading distance is less than 9 mm and the plate barrier cannot be read. The existence of obstacles makes reading the e-KTP card will be reduced.

Abstract

In swallow nest cultivation, swallow breeders still have difficulty in tropical climates, one of which is maintaining the temperature and humidity in the swallow nest room to be stable and to know the value of swallow population. When the temperature is hot, the swallow room will become dry which impacts on the nest is damaged and the swallow is not comfortable living there. Therefore, a system that can be easily managed by swallow farmers is made so it can help reduce hot temperature and lack of humidity in the swallow nest room by using a sprayer that works automatically. In this system, there are temperature and humidity detection module which functions to detect the temperature valueand humidity when the room is hot / dry, the detected value will be processed by the microcontroller so that it gives an active sprayer command if the room temperature is hot, while the swallow detection module that uses infrared sends the movement value if there is a moving object. The value of the system will be sent to a cloud database which will be conveyed via the farmer wallet smartphone application. The accuracy level of the infrared detector sensor module and the air humidity sensor is very good, so that it can control the temperature conditions in the swallow room which is 27 degrees C and a stable humidity at a value of 80%. The stability of temperature and humidity produces swallow nests which have high selling value.

Abstract

Analog telecommunication system equipment is now starting to develop and be replaced with digital telecommunication systems, one of them is in the audio signal processing. The focus of audio processing is audio crossover. Audio crossover in development there are still many who use analog systems. This analog system has disadvantages when adjusting the sound balance because it still uses analog filters to balance it. It is necessary to develop a technology that aims to create a digital-based crossover audio system using the STM32L4, so that by using this digital-based signal processing it is able to adjust the sound more specifically than the signal processing used analog based. This digital filter uses the Finite Impulse Response (FIR) method. Testing audio crossover using STM32L4 produces a digital-based crossover audio system design using a STM32L4 microcontroller with a voltage of 3.3V as power supply, mp3 player as sound input device, FIR filter as digital filter processing, LM386 as sound amplifier and speaker as sound output for crossover audio on rangelow frequency (200Hz to 4000Hz), high (2200Hz to 6000Hz), medium (200Hz to 4000Hz).

Abstract

Securing detention rooms in Indonesia, using manual methods from humans to secure them. Officers check the detention room periodically. Several cases that occurred, such as the escape of prisoners from the Cawang Police and the Lhoksukhon Detention Center, the detainees broke into the bathroom wall using metal bars to be used as a media for breaking the walls. To prevent recurrence of cases, an early detection design is needed when there is a detention room indicated that it will be damaged by installing a vibration detection device on the wall. In this study, the SW-420 vibration sensor is used as a vibration detector when there is a wall to be broken into and several cameras installed in the corridor to visually monitor the occupants of the detention room. Vibration data will be sent to the detention room website via Arduino Uno, while the IpCamera will be connected to the router to display the video capture results on the website. For example, the bathroom plan for the detention room at the Gondanglegi Police Station that has been made, the sensor node is placed at the center point of the bathroom wall at a position of 60 cm which divides it into 2 parts. Arduino Uno will dynamically have IP when connected to the router using a Lan cable. Based on the experiment in the previous chapter, how to adjust the sensor sensitivity can be done by turning the sensitivity adjustment and adjusting the threshold on the website code.

Abstract

The development of the Indonesian agricultural sector until 2014 according to the Strategic Plan data of the Ministry of Agriculture for 2015–2019 is about 3.90% of the economic sector. One of the most important parameters for improvement efforts is soil. Soil quality on agricultural land is one important thing that needs special attention in its management. It is not easy to create ideal soil conditions for plants. For that, farmers need to know the variables that affect ideal conditions. The easiest way to find out the variable is to measure the pH and humidity of the soil conditions. Evaluation of soil fertility in chili plants is still done manually through visual observation. One of the factors that makes chili plants die before they bear fruit. In this research, a web monitoring system will be made on the planting medium of chilies based on soil acidity and soil moisture using sensors that can be monitored online. Data will be stored in the database and displayed on the web. The results obtained on the growing medium of chili plants produced soil suitable for chili plants, namely soil media sandy which has a moisture value of 7 to 8 and a pH value of 6.5-7.5. The average time needed to communicate between nodes to the website is 344 ms, which in the TIPHON standardization the average value of delay in sending data from the device to the website belongs to the 3rd index, which means that the process is of moderate quality.

Abstract

PH is the standard value of degree of acidity expressed on a scale 0-14. PH can be influenced by several factors such as temperature and CO2. Acidification occurs because CO2 enters the liquid in the form of dissolved gas then reacts with water to form a salt in the form of carbonic acid. The acidity can be determined by measuring the pH. PH measurement is an activity to determine the value of degree of acidity. PH measurement is needed to reduce the impact on the environment because pH is closely related to pollution. However, the existing measurement tools are still manual, while real time measurement is needed so the impacts on the environment can be prevented. In this study, a system that can measure pH which is influenced by CO2 concentrations in real time was created. This system consists of CO2 sensor, pH sensor, Arduino UNO R3 and Raspberry Pi. Apart from real time, the advantage is its ability to perform data acquisition using programs written in the Python 3.x programming language, so that data can be presented in tables and heatmaps. The results of sensor readings from the microcontroller to the raspberry pi can operate properly with delivery times via USB. Overall testing the system at reading the pH value is as expected, able to read the change in pH value significantly in pH of a neutral solution (7.3) and read the change of pH value that is relatively the same after the solution is injected with CO2.
