<![CDATA[Rice is the staple food of the majority of Indonesians and most of the population work as farmers. However, the amount of rice produced are still insufficient. To meet the rice needs for the society, it should increase the amount of rice production by focusing on rice field quality such as the water level rice fields. In this study a prototype rice field irrigation system is designed using AWD irrigation method by regulating open activation and closing the inlet gate and exit gate based on the age of paddy which are calculated using RTC and the height of paddy water measured using ultrasonic sensors. The system also designed to receive input from the age of paddy and deactivate the system from the mobile application through the ESP8266 module. Test results from this system can measure water level with accuracy of 95.68% and read real-time time with 98.67% accuracy. The servo motor NFC DS04 works to open the door with a duration of 60 seconds and closes the door with a duration of 56 seconds. The paddy irrigation regulating system can regulate the water level with a success percentage of 81.48%. The system can receive input and deactivate the system with a percentage of success of 70%.]]>

<![CDATA[Disaster is a sudden event, such as an accident or a natural catastrophe, that causes great damage or loss of life. Disasters can occur at any time, therefore a mechanism is needed to evacuate out of the building during a disaster. Generally public facilities have provided instructions and evacuation routes outside the building. Based on the severity of the disaster and the evacuation capability of the victim, the evacuation strategy can range from evacuation as soon as possible, evacuate slowly, move to a safe location inside the building or take refuge in the available protection room and wait for the rescue team to arrive. The algorithm for finding the shortest paths can be used to determine the evacuation route. But this path is still static, if the route damaged in then the evacuation route would become useless. The time for the evacuation process can also increase if the condition of the evacuation route is not known whether damaged or not. The solution to solve this problem is to make a system that can help find the safest and shortest evacuation routes during emergencies. This system consist of microcontroller Arduino Mega to control the system and led for evacuation sign. The evacuation routes is determined by implementing dijkstra algorithm with priority queue to search the shortest path.]]>

<![CDATA[Indonesia terletak di daerah rawan bencana, khususnya gempa bumi. Salah satu daerah rawan gempa dan tsunami adalah Kota Padang. Oleh sebab itu diperlukan upaya untuk memudahkan masyarakat melakukan pencarian lokasi shelter evakuasi jika terjadi gempa besar yang diiringi bahaya tsunami. Paper ini menejelaskan sistem penilai kelayakan bangunan bertingkat sebagai shelter tsunami (SPEAKS). Keunggulan dari SPEAKS adalah mampu memberikan penilaian kondisi bangunan tinggi untuk dijadikan lokasi shelter evakuasi sesaat setelah terjadinya gempa bumi. SPEAKS melakukan perbandingan gambar bangunan sebelum dan sesaat setelah terjadinya gempa menggunakan cross-correlation template matching yang dilanjutkan dengan penilaian kelayakan sebagai shelter evakuasi dengan logika fuzzy. SPEAKS merupakan distributed-sensor-node terdiri dari end-node dan broker yang diletakkan pada lokasi bangunan tinggi. Server sistem digunakan untuk menyimpan data hasil analisa kondisi bangunan oleh end-node menggunakan protocol mqtt. Pengujian fungsional SPEAKS dilakukan dengan lima skenario uji. Hasil pengujian menunjukkan SPEAKS mampu melakukan penilaian kondisi bangunan dalam 135 detik setelah asumsi gempa terjadi.]]>

<![CDATA[Sebagai ibu kota Provinsi Sumatera Barat, Kota Padang memiliki risiko tinggi terhadap gempa bumi dan tsunami karena letaknya di antara dua lempeng benua dan adanya Patahan Semangko. Beberapa tempat perlindungan di Padang berfungsi sebagai lokasi evakuasi dan penyelamatan saat terjadi tsunami. Paper ini menyajikan sebuah sistem pendeteksi gempa bumi yang menggunakan sensor terdistribusi. Identifikasi gempa bumi dilakukan dengan menghitung nilai Peak Ground Acceleration (PGA) dari gelombang P dan gelombang S menggunakan sensor piezoelektrik dan akselerometer. Sistem yang diusulkan merupakan jaringan sensor node terdistribusi yang berkomunikasi menggunakan protokol MQTT. Untuk mengevaluasi kinerja sistem, kami mengimplementasikannya menggunakan Raspberry Pi, sensor piezoelektrik, akselerometer MPU-6050, dan modul Xbee untuk komunikasi data. Hasil eksperimen menunjukkan bahwa sistem ini dapat mendeteksi magnitudo dan intensitas gempa bumi dengan akurat.]]>

<![CDATA[Lora technology is implemented on prototype to carry out a Tsunami early warning system by sending a trigger code to sound the arduino. the sender uses Dragino LoRa LG01 outdoor while on the other side uses Dragino LoRa node and Arduino Mega. Triggers are input data from Dragino LoRa Gateway in form of string of data which is then converted and sent via LoRa communication. The data that arrives at the node will trigger the program to turn on the siren that has been keep in Arduino Mega. The application of this LoRa is to turn on the sire with a maximum distance. In this research also calculated the capacity of resource at the node that will be sent to the Gateway each time the trigger code is sent. Tests carried out in sub-urban areas with several distance parameters. The maximum distance that can be reached is 500 meters with Receive signal strong indicator (RSSI) -95. While the average time span since the trigger is sent untill the siren is sounded is 0.45 seconds.]]>

<![CDATA[The objective of this study is to create a water turbidity detection system, aiding customers of a municipal water supply company in preserving the quality of water for everyday use. The aim is to prevent the mingling of stored clean water with turbid water when the tap is turned on. To achieve this, we employ a smartphone as a remote control device, enabling users to monitor the water's condition remotely. The study's findings demonstrate that this system adeptly manages the water separation process based on its condition, allowing manual control via Bluetooth communication within a maximum range of 10 meters. This setup provides two control options: activating and deactivating the water channel through a solenoid valve. Test outcomes indicate the system effectively segregates the water as per its condition and promptly follows user directives.]]>
