Windmills are a tool that can be used to convert kinetic energy in the wind into mechanical energy. The kinetic energy in the wind is in the form of translational energy which is converted into rotational energy and then it can also be used according to a need. Its main task is to convert wind energy into electrical energy, apart from that a windmill is also needed to be able to protect itself from the enormous ferocity of the wind. Protection is carried out at a windmill to prevent overspeed. If there is no protection system, the rotor will rotate to the limit of the capacity of a generator, blades and other rotor components so that it will malfunction and cause danger. In this study, a continuous rotation servo motor is used to control the direction of the windmill with a limited output voltage value. The prototype of this windmill was tested with a wind speed engineered using a fan as the direction of the wind. If the voltage value is below or above the output voltage value limit that has been programmed on Arduino, the servo motor on the windmill will rotate CW 90 °. If the output voltage value is within the normal range, the windmill does not rotate to receive the wind energy it receives. For the test results that have been carried out, the results obtained in the first test when the fan condition is Off, the windmill produces an output voltage of 0V and the windmill rotates CW 90 °. In the second test, when the fan is on, the windmill produces an output voltage of 2.25V, in a condition the windmill does not rotate. Then the fan starts off and produces an output voltage of 0.93V then the windmill rotates 90 ° CW. In the third test when the fan is on and after that the speed of the fan is increased to test the windmill so that it can rotate when getting the upper limit voltage value. When the fan is on, the windmill produces an output voltage of 2.61V on the gauge and the windmill does not rotate. Then the fan speed is increased and rotates CW 90 ° when it gets an output voltage of 3.36V. Keyword: Direction, Windmill, Control, Horizontal Axis, Servo Motor

Youtube is an application for sharing videos that users can access for free. In the results of a survey that has been carrying out for many users who use Youtube, they experience buffering due to the slow internet network. Therefore, bandwidth management is needed that aims to manage and control customer bandwidth so that bandwidth usage can be evenly distributed by using the Queue Tree Method on Mikrotik. The Queue Tree method is a method that can divide bandwidth by marking the service from the package used by the customer. This research was conducted for five days by comparing the existing conditions and conditions using the Queue Tree Method based on testing one of the Quality Of Service (QoS) parameters such as Delay. The results of the study concluded that the analysis carried out on the QoS Parameters for the Youtube in Existing Conditions obtained a considerable Delay value in the Afternoon time of 524,87 ms, including the Bad Category and the Delay value obtained in Queue Tree Conditions of 11,83 ms included in the Very Good Category. In this case, using the Queue Tree Method, the network quality is better than the existing network conditions because of the bandwidth usage that is distributed evenly to each customer.Keywords: Youtube, Bandwidth Management, Queue Tree, Quality of Service.

POWER SUPPLY MANAGEMENT SYSTEM DESIGN ON NODE EARLY WARNING SYSTEM FOR PEATLANDS FIRE MITIGATION Taufiq Muammar; Rahyul Amri; Yusnita Rahayu
SINERGI Vol 22, No 1 (2018)
Publisher : Universitas Mercu Buana

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.

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.

Chicken eggs can be hatched in two ways namely, incubated by a hen directly and by using a created egg hatching machine. The egg hatching machine replaces role of the hen in egg incubation process. Checking hatching machines manually by checking the stabilities of temperature and humidity in the hatching room one by one, cause temperature and humidity instabilities to be a problem, so eggs are failed to hatch. This problem can be solved by using monitoring and pengendalian system of a hatching machine uses XBee Tansmitter and XBee Receiver in 5meters,10meters,20meters indoor. XBee Tansmitter is on incubation machine connected to Arduino-Uno-ATMega328. DHT22-Sensor detects temperature and humidity readings. XBee Receiver is on user’s space connected to Arduino-Uno-ATMega328. SD Card saves temperature and humidity data. Temperature and humidity monitoring in 24 days since eggs were put into hatching machine in 37.80C–38.70C temperature and humidity of 50%-60%. After 3 days eggs put into machine, Servo Motor turns back 1800 Egg’s rack within eggs every 3 hours, until eggs hatch. Eggs hatched since 19th day. Total of hatching eggs are 19 from 23. Can be concluded that the research work well because hatching eggs well reached 82.61%.

Telah dilakukan suatu pembuatan detektor panas nirkabel dengan modul pengiriman data dengan sistem pemantauan jarak jauh untuk stasiun monitoring kebakaran hutan. Sistem ini terdiri atas empat komponen utama sensor suhu LM35, modul pemancar HX2262, modul penerima HX2272 dan mikrokontroler AT Mega8. Sistem pengiriman data yang digunakan dalam modul ini adalah sistem FSK (Frekeunsi Shift Keying ). Sensor suhu LM35 memiliki karakterisasi linier kenaikan suhu sebesar 1 o C maka nilai tegangan keluaran akan naik sebesar 10 mV. Program yang digunakan merupakan bahasa pemrograman tingkat tinggi yang mudah dimengerti. Program ini akan dikompile ke dalam mikrokontroler menggunakan Downloader dan dibantu dengan software AVR Studio 4. Hasil penelitian ini menyatakan bahwa pada saat dilakukan pengujian pada suhu 50 o C diperoleh waktu sekitar 20-30 detik untuk mengirim data ke modul penerima dengan jarak 100 meter dan memiliki amplitudo sebesar 1.6 cm dalam kondisi Low dan dalam kondisi High amplitudo naik 2 cm yang dapat dilihat di osiloskop. Modul ini akan mendeteksi panas di sekelilingnya dan apa bila ada suhu yang melebihi suhu referensi 50 o C yang telah diset di dalam program bascom maka modul pemancar akan mengirimkan data ke udara dan akan ditangkap oleh modul penerima sehingga dapat ditampilkan di monitor .
