Penelitian dengan membangun alat pendeteksi asap rokok menggunakan sensor MQ-2 berbasis Arduino Uno menghasilkan analisis bahwa semakin besar kadar asap rokok yang terdeteksi sensor maka semakin tinggi nilainya. Menggunakan Sensor MQ-2 digunakan untuk mendeteksi kondisi kadar asap rokok pada ruangan bebas asap rokok dimana pada saat sensor berada dibawah nilai ppm < 200 maka kondisi ruangan dalam kondisi normal pada saat sensor mendeteksi ppm antara 200 sampai dengan 300 kondisi ruangan dalam keadaan waspada, sedangkan saat sensor mendeteksi lebih dari 300 kondisi ruangan dalam keadaan bahaya dan kipas dc berputar untuk menetralisir keberadaan asap rokok. Kemampuan pendeteksi asap rokok ini akan mendeteksi keberadaan asap rokok di udara tergantung dari sudut sumber asap rokok dan waktu pembacaan pada sensor serta arah pergerakan asap rokok. Proses pengiriman data dari input ke output dilakukan dengan menggunakan ketika sensor MQ-2 mendeteksi asap rokok, sensor MQ-2 akan mengirimkan sinyal ke Arduino Uno untuk mengaktifkan output. Jadi hasil penelitian Setelah merancang prototipe sistem dan mengujinya, dapat diketahui bahwa pendeteksi asap rokok dapat diterapkan pada ruangan bebas asap rokok.

Monitoring realizes efforts to improve the quality of health services. To obtain information on patient condition data during treatment. The monitoring process is done manually. So that it has an impact on the service and condition of the patient during treatment. The design of monitoring the patient's body temperature and heart during treatment with IoT can be controlled through the NodeMCU sensor ESP8266, MLX9014, MAX30100 sensor and Arduino IDE software program. Furthermore, it can detect the patient's temperature and the patient's heart rate during treatment. And processed by the NodeMCU ESP8266, the data from the two sensors is displayed on the SSD1306 OLED LCD and also to the smartphone of the medical officer on duty via Blynk. In order for the tool to work properly and optimally, it is necessary to adjust the pin placement so that it can work optimally. The problem of internet connection interference causes delays, resulting in a mismatch between the measurement of the test equipment and the standard tool. Data values are taken with an accuracy of 70%-93% for the MAX30100 sensor, for the temperature sensor it is close to optimal with a value that is read on a standard tool with an accuracy of 97%-99%.

The innovation of the robot cars today is moving very fast. The robot car is capable of being driven without using manual remote controls. One form of technological development in robot car control is by using hand gestures. The microcontrolle placed in the palm of the hand will read the direction of movement of our hands, then the instructions are transmitted to the robot car.  The transmission system used in the microcontrolled circuit in the palm of the hand and the receiver circuit inside the robot car must be properly attached. This is influenced by the quality of programming language levels and the arduino mini pro and MPU-6050 circuits. Hand gesture directional readings are able to be easily readable and directly transmitted by the NRF24L01 module via radio waves. The response power of the robot car in receiving hand-move instructions can be received as far as 45 m. In addition to using a good arduino mini pro, the addition of antenna modules will also increase the quality and distance of the connection is getting farther..

The sprayer is one of the equipments that is often used in agriculture, especially in rice plants to control pests and diseases. The use of the nozzle rod on the electric sprayer still uses hands resulting in the spray distance on the rice being not constant. To answer this problem, the researcher will create an innovative robotic hand holding the nozzle rod on an electric sprayer that will direct the nozzle rod constantly. Servo MG996r as a rectifier of the motion of the nozzle stem which will determine the distance and area of ​​spraying on rice. To achieve maximum dispersion in rice with a 4:1 legowo system with a servo rod length of 50 cm and a spacing between rice of 25 cm, the servo must move forward and backward at an angle of 110° - 180° which can be seen on the LCD and the distance of the nozzle rod on the object can be up and down to 38 cm and up 24 cm from the starting position. The results obtained by the robotic hand holding the nose bridge can work optimally.

The climatic chamber is a calibration medium for the thermohygrometer. This simple climatic chamber was built using the Arduino uno, DHT22 sensor, heater, and peltier. The climatic chamber was designed and manufactured well and cheaply. Climatic chamber testing of the design results is carried out to determine the success rate of the tool. Tests are carried out using the Madgetech data logger tool through monitoring or monitoring of temperature within a certain period of time. The results of temperature monitoring at two observed values, namely temperatures of 250C to 300C and temperatures of 300C to 350C, showed good results with the corresponding rhythm of temperature increase and temperature decrease. It's just that the decrease in temperature still takes longer than the increase in temperature. This shows that the heater can be said to be working optimally and the peltier is not fully working. So it is necessary to do further studies related to the peltier for the climatic chamber both in terms of number and characteristics.

Security Parking UIN Walisongo Semarang at this time can be said to be in poor condition. The high case of loss of a motor vehicle cause anxiety for the academic community. Parking system that is traditional that is doing the checking of identity cards at the exit of the campus is less effective. Hence the need for a system of security parking modern and computerized, so that activities out of the vehicle can be recorded and stored automatically. Based on these problems, the authors designed a parking Security System as a WEB-based form of increased security parking campus UIN Walisongo Semarang. By using RFID technology (Radio Frequency Identification) are planted on the card identity, which can later be used as an authentication tool typing will enter and exit the campus area. To provide double security, there are Features of the Live Camera with the base website that serves as a tool for monitoring vehicles that are parked in real time. The output of this final project is to produce a prototype security system parking. Not only specialized hardware, but also software design of the System monitoring of vehicles in live Web-based. So the users of the parking facilities can monitor the vehicle anywhere.

The community's need for electricity is getting higher, so alternative energy sources such as solar heat are needed to replace energy sources from fossil fuels in meeting electricity needs. In this paper we design a two-axis solar tracker with an LDR sensor. A sun tracking system is a unit that is combined into one to control the position of the tracking device with the aim of making the surface of the solar panel module always facing the direction of sunlight. This research discusses the Prototype of the Sun Tracking System in Arduino Based Solar Power Generation Systems to get maximum solar energy. This system will make solar panels move automatically so that sunlight absorption can be maximized. The main control uses Arduino nano which gets input values ​​from the LDR sensor then is processed to the output system. With the control system method can automatically be seen the difference in the results of a fixed solar panel with a solar panel with a tracker, from the comparison we get a solar panel with a tracker to get more optimal results.  

Hydroponics are now increasingly in demand, should be checked regularly so that hydroponic plants thrive. Likewise, in Siliwangi Indah Hydroponics Semarang, which still uses manual methods, namely the absence of a device that detects nutrient water temperature and pH automatically and the absence of tools that can normalize nutrients automatically. Arduino Uno R3 can be used to detect temperature automatically with a temperature sensor DS18B20, and detect pH with a pH sensor. Then the sensor readings are sent to the farmer's cellphone with SMS Gateway. The sensor readings are also used to divert the flow of nutrients from the spare reservoir, so that the nutrients remain normal. So this tool can automatically measure the nutrient water temperature and pH and replace the main nutrients to the reserve nutrients. And the assessment obtained from experts on this tool gets a value of 3.6 and from the expert gets a value of 3.7. Hydroponic nutrition in this study is maintained normally and farmers always know the nutritional state. So that the hydroponic plants thrive and have maximum yields.
