Abstract

Early warning system is one of the technology to detect land fires by utilizing a network of wireless sensors. Constant data transmission by the sensor nodes consumes a large amount of energy on the nodes’ sides that could affect the battery’s longevity. This research is done to discover the amount of power consumption and battery longevity during fire emergencies, and during non-emergency situation on peatlands. Power saving on the fire detecting system uses an LM35 temperature sensor, ATmega8 micro-controller and HC-12 transmission module. The overall result of powered by a 9 volt battery during fire emergencies, and during non-emergency, the power consumption reaches up to 1 Wh, with various longevity levels of the battery. The implementation of sleep/wake up mode scheduling during fire emergencies and non-emergencies could save battery for 2 hours compared to those without the power saving mode implementation. Power saving during fire emergency could be minimalized by activating the sleep mode activation power-down on the micro controller and it can also set the data transmission schedule to minimalize data usage during fire emergency, so that the usage of sleep/wake up mode interval scheduling during transmission could minimalize energy consumption and elongate the power supply active period.

Abstract

Fire Robot serves to detect and extinguish the fire. The robot is controlled by the microcontroller ATMEGA8535 automatically. This robot contains of several sensors, such as 5 sets of ping parallax as a robot navigator, a set UVTron equipped with fire-detecting driver, DC motor driver L298 with two DC servo motors. The robot was developed from a prototype that has been studied previously with the addition on the hardware side of the sound activation and two sets of line detector. The robot will active if it receives input from the sound activation unit and will start to find the fire with “search the wall” navigation techniques. The line sensor was used as a door and home detector and circle the fire area.To extinguish the fire, this robot uses a fan driven by a BD139 transistor circuit. The overall test results show that the robot can detect the presence of the fire in each room. The robot also can find the fire and extinguish it within 1 minute.

Abstract

The problem of forest and peatland fires in Riau has become main topic to prioritize its revamping. Land and forest fires in Riau until reached 3,700 hectares area, happened in some last years,.Forest and peatland fires occured in the majority of districts in Riau Province, from low category of 4 hectares until 2,800 hectares. This researchdiscusses aboutanalysis of controlling wirelessTemperature Sensor for monitoring Peat-Land fire by using LM35 Temperature Sensor, Transmitter-Module (HC-12), Receiver-Module (HC-12), Arduino-ProMini to produce outputs on LED, LCD, Buzzer. Detector of Peat-Land fire works when it is burning, so heat will spread through aluminium stalk and be read by Temperature-Sensor1 upto Temperature-Sensor4. Output of each sensor is sent to each control block of Arduino-ProMini in Transmitter-Module(FU1?FU4). From Arduino-ProMini, it is sent toReceiver-Module(FU5). Receiver-Module only receives one data from Transmitter-Module in one time. Every data is received by Receiver-Module goes to Arduino-ProMini, processed to produce outputs on LCD that shows ID of FU1?FU4, Peat-Land Status, temperature of Peat Land. If LED is Green, Peat-Land not burned, LED shows SAFE Condition, Buzzer Off. If LED is Yellow, Peat-Land burned underground, LED shows BE-CAREFUL Condition, Buzzer On. If LED is Red, Peat-Land burned on the ground, LED shows DANGER Condition, Buzzer On. Temperature 0°C?21.9°Cis SAFE Category because Peat-Land not burned. Temperature 22°C?28.4°Cis BE-CAREFUL Category because Peat-Land burned underground. Temperature 28.4°C?50°Cis DANGER Category because Peat-Land burned on the ground. This equipment works as its frame work.

Abstract

FM demodulator is used to demodulate signal in FM receiver. Demodulation process is performed to recover the information signal. The information signal is 3.4 kHz which ismodulated with a carrier signal of 19 kHz. FM demodulator is designed with PLL (Phase Locked Loop) method, it used the concept of phase locking signal. FM demodulator withPLL method consist of four blocks, that is phase comparator, second-order Butterworth LPF, VCO wienbridge, and buffer amplifiers. Design of FM demodulator trainer begins with calculate to determine the component value which suitable with cut off frequency.

Abstract

Kebakaran lahan gambut yang sudah meluas menimbulkan bencana asap dan penyakit pada masyarakat. Pemantauan kebakaran lahan gambut yang memiliki tingkat akurasi tertinggi adalah ASEAN Specialized Meteorological Center (ASMC) dengan tingkat akurasi sebesar 60%. Dibutuhkan perancangan pendeteksi kebakaran lahan gambut, guna untuk mitigasi bencana kebakaran lahan gambut. Karena gambut yang ada di provinsi Riau umumnya adalah gambut jenis kayuan, jadi penelitian dilakukan pada gambut kayuan. Beberapa metode pengambilan data pada penelitian ini yaitu: uji laboratorium, pengambilan data di lahan gambut kondisi normal, pengambilan data di lahan gambut saat kejadian kebakaran dan pemetaan simpul. Berdasarkan hasil penelitian ini, sensor suhu LM35 memiliki tingkat akurasi dengan persen error rata-rata sebesar 0,22%. Suhu lahan gambut kayuan saat kondisi normal memiliki besar suhu yang selalu berada di bawah suhu udara sekitar. Saat kondisi terbakar besar, suhu lahan gambut kayuan terus meningkat dan melebihi besar suhu udara sekitar. Suhu udara sekitar saat kondisi normal atau saat terjadi kebakaran tidak ada perbedaan yang mencolok, karena kebakaran lahan gambut kayuan tidak begitu bergemuruh perubahan suhu udara sekitar. Radius sensor suhu LM35 pada alat pendeteksi kebakaran lahan gambut mencapai 4 m dengan lama waktu pembacaan 45 menit.

Abstract

Efforts and strategies have been done both by the providers of electrical energy and the government to handle the increase in electricity demand.  However, there has been no satisfactory result. The government has set a major policy on energy management, namely conservation and energy diversification in order to reduce dependence on non-renewable energy sources and utilize renewable energy available in areas where power plants will be built to meet the growing demand for electricity. Riau Province in addition to located in tropical climates and many of its areas are on the coast that its existence is very far for affordable network of PLN electricity, therefore the provision of solar power plant is one appropriate alternative, to meet the needs of electrical energy for the needs of the population. While the output voltage generated by solar cells is not constant, but it depends on the natural conditions that at any time vary the intensity of sunlight, so that the output voltage of the solar cell is also not constant and varies throughout the daytime. In general, commercial equipment has specification limits for ± 10% voltage variation. Disturbances such as voltage varization, if not handled seriously can cause damage to consumer electrical equipment, in addition to the use of electrical energy, in the form of varying output voltage resulting in expensive cost. To overcome the problem of voltage variations produced solar cell can be used prototype dc to dc converter using boost converter technology, which  automatically  adjust  the  output  voltage  according  to  the  desired  voltage.Designing  DC  to  DC Converters To Stabilize Solar Cell Outputs Using Boost Converter Technology has been tested for performance through the output voltage of a 100 WP solar cell panel whose values vary from 13.5 volts to 20.8 volts as a boost converter input and produce a regulated output voltage 24 volt. Based on the results of prototype testi ng dc to dc converter using booast converter technology that has been designed to produce a voltage regulated voltage of 24 volts direct current declared valid. The valid intent here because the output voltage is still dirange 24 volts ± 10%.
