Teknologi roket dapat digunakan sebagai alat pertahanan. Di bidang militer jenis roket yang digunakan adalah peluru kendali (rudal). Jenis rudal yang paling terkenal adalah rudal jelajah. &nbsp;Rudal jelajah terbang dengan lintasan <em>horizontal</em> menuju target. Rudal jelajah menggunakan sayap sebagai pembangkit gaya aerodinamika untuk mengontrol gerakan sewaktu mengudara. Pada intinya rudal jelajah adalah pesawat tanpa awak yang dirancang untuk membawa hulu ledak konvensional dengan jarak ratusan kilometer. Agar dapat mencapai target secara <em>autonomus</em>, rudal jelajah harus memiliki sistem <em>control surface</em> otomatis yang dapat membetulkan arah saat terbang sesuai dengan misi. Sistem navigasi yang baik akan mengarahkan rudal jelajah pada target dengan akurat. Sistem navigasi dapat menentukan posisi, kecepatan, dan sikap dari rudal jelajah. Penelitian ini akan membahas mengenai perancangan sistem navigasi pada rudal jelajah. Sistem navigasi ini akan digunakan rudal jelajah yang akan diikutkan pada kompetisi. Dalam penelitian ini, sistem navigasi yang dibuat akan berbasiskan pada <em>waypoint</em>. Pada sistem ini posisi dari rudal akan terus menerus diperbaharui agar sistem dapat mengarahkan rudal pada sasaran dengan akurat. Dengan mempertimbangkan faktor keamanan, motor elektrik dan baling baling berjenis <em>ducted fan </em>dipilih sebagai pengganti tenaga pendorong pada rudal jelajah konvensional. Ini mengakibatkan perubahan parameter seperti pada kecepatan, getaran, daya angkat, dan daya dorong. Berdasarkan hasil pengujian, sistem mampu merespon perubahan arah lintasan terbang pada rudal agar mendekati target sebesar 100% dan mampu mengarahkan rudal jelajah pada target dengan galat sebesar 30%, dengan parameter keberhasilan mencapai target yang memiliki radius sejauh 15 meter kemudian melakukan separasi.</p> <p><strong>Kata kunci<em> :</em></strong> Rudal jelajah, Sistem navigasi, <em>Ducted fan</em>,<em> Waypoint, Control surface.</em></p> Muhammad Aria Iqbal Hasan Suteja Rizqy Gunawan Ichsan Jatnika ##submission.copyrightStatement## 2019-04-29 2019-04-29 7 1 42 53 10.34010/telekontran.v7i1.1644 Monitoring System for Broiler Chicken Farms Based on Internet of Things (IoT) https://ojs.unikom.ac.id/index.php/telekontran/article/view/1641 <p><em>In this study, the author made a monitoring system for dangerous gas levels, temperature and humidity in the chicken coop. This system can inform air quality in the form of ammonia gas, methane gas, temperature and humidity contained in the chicken coop and provide readings of gas data that are considered dangerous, unstable temperature and humidity to workers in the chicken coop and can be viewed on a platform basis. The system generally consists of two sensors, namely the DHT11 sensor to detect temperature and humidity in the chicken coop, and the MQ135 sensor to detect ammonia gas levels in the chicken coop, and connect to the internet network through the ESP8266 module with the Arduino Mega 2560 microcontroller which aims to upload data sensors to the Firebase web and displayed in graphical form as a means of information on the chicken coop. The test is carried out in three stages, namely connectivity, functionality, and delay. The connectivity test proves that ESP8266 can be connected to Access Points and internet networks, functionality tests prove that sensors can read gas, temperature and humidity and retrieve data. And lastly is testing delay, which is counting the length of the process from the beginning of sensor reading to data up to Firebase's Internet of Things (IoT) -based web. From the results of calculations that have been done in testing, it was found that the time needed for one shipment takes as much as 5-19 seconds. Of course, this time can change because there are aspects that can inhibit internet connection, the number of devices connected to an internet network, but the purpose of this research has been completed with what was expected.</em></p> <p><strong><em>Keywords : </em></strong><em>Hazardous Gas, Temperature and Humidity, Gas Sensors and Temperature and Humidity Sensors, Firebase</em><em>.</em></p> Ari Ajibekti Masriwilaga Tubagus Abdul Jabar Malik Al-hadi Agus Subagja Sopian Septiana ##submission.copyrightStatement## 2019-04-29 2019-04-29 7 1 1 13 10.34010/telekontran.v7i1.1641 Detection of Vehicles Number Plate Using Image Processing with Template matching Method https://ojs.unikom.ac.id/index.php/telekontran/article/view/1634 <p><em>To design a system in order to identify an object number plate for the Indonesian format, an initial system is designed, in the form of a vehicle licence plate recognition application using template matching method. The goal of this application is to be implemented to the parking system by identifying the number plate. This system uses the camera for the image capture process, by utilizing image processing technology with the matching correlation template method for recognition to produce a string value from the image. Before doing recognition process, First, the pre processing stage is performed on the input image which includes grayscale, binary, until the segmentation stage before the correlation / comparison process is carried out on the image of Template. The process that occure in the pre-processing unit done for some reason including to make the image lighter and less complex. This process will make the image easer to be processed and also to increase the proses speed of the system. Before aply template matching algorithm to the image output from segmentation process, the image has to be resized first to match the size of the template image stored in data base. This has to done so that the target image and the template image can be match directly with template matching algorithm.&nbsp; The output of this system is a string value which is refer to the value of the license plate capture by camera used by the system. </em><em>The problem that arises in the introduction process is how to identify various types of characters with various sizes and shapes so that the string value is the same as the text image.

To anticipate this, the discipline and concentration of the driver when driving is needed. However, when drivers have discipline and sufficient concentration of accidents can still occur. Therefore, the quality of the vehicle security system also greatly affects safety when driving. With the development of science and technology today it is very possible for humans to make security systems in vehicles. Accidents are often caused by the driver being unable to react quickly when there is a sudden blocking of objects. Especially when the driver is driving at high speed. This can be overcome by automating the braking system, so that the vehicle's speed will slow down even though the driver does not step on the brake lever. So that the possibility of an accident can be avoided. And automation is expected to be implemented in vehicles widely. In this study, designed a brake automation system using fuzzy logic by making a prototype. This prototype serves as a visual aid to evaluate the workings of the membership functions that will be used. From this evaluation it is known the value of each membership function. These values ​​are used as the main parameters in determining the Rules that will affect the output value of the brake force. With these Rules, automation of the brake system can work optimally. And it is known that the distance of the prototype car can run between other obstacle with a width of 50cm and the braking of the prototype car stops completely when the prototype is ± 5-10 cm with the obstacle in front of it.</em></p> <p><strong><em>Keywords</em></strong><strong><em>: </em></strong><em>Automation of Brake Systems, Fuzzy Logic, Distance, Speed</em><em>.</em></p> Rodi Hartono Fajar Petrus Apris Samosir Okta Rusdiansyah Rizky Naufal M ##submission.copyrightStatement## 2019-04-29 2019-04-29 7 1 54 65 10.34010/telekontran.v7i1.1637 Monitoring System for Soil Moisture, Temperature, pH and Automatic Watering of Tomato Plants Based on Internet of Things https://ojs.unikom.ac.id/index.php/telekontran/article/view/1640 <p><em>Diera Digitizing today almost all equipment uses technology. One benefit can be applied to agriculture, namely the internet, from things to monitor agricultural ecosystems and can be used as a reference for farmers in making decisions. This system is designed so that farmers can know the parameters of determining soil membranes, temperature, pH and watering and liquid fertilization are used to influence the growth of tomato plants, and facilitate farmers in relation, implementing this system can minimize crop recovery caused by weather factors, reduce nutrition , etc. Through the implementation of this support system, farmers are expected to produce tomatoes that are better and more suitable for consumption by the community. System testing and placement is carried out in a greenhouse where in several measurement parameters such as in the air and pH must be in accordance with the ideal level of tomato plant data, the optimal data level is between 60% -80% so it is not too dry for water, 24- 28 degrees Celsius, and pH is stable 5-6.

As the largest palm oil production country in the world Indonesia has many developing palm oil companies, both national and international. To monitor the vast oil palm plantations, a cheaper and more efficient technological innovation is needed. In order to observe the vast plantation area and the different topography of the land, which can complicate logistical access especially if there is rain making access difficult to pass, we conduct research on monitoring and mapping oil palm plantation areas. The monitoring function is to monitor plantation logistics lines such as, finding a faster route by looking at the contour of the land so as to facilitate transportation access from collectors to each existing post. As for mapping, it functions to map an area of ​​225 hectares with the aim of assessing the condition of oil palm plantations, especially assets from the garden itself. this activity is commonly referred to as landholders by surveying assets or inventory. The use of mapping techniques using unmanned aircraft has several advantages, one of which is more accurate mapping than using satellite imagery. From this mapping data can be developed again such as census mapping data, land use maps, land use planning, and monitoring of pests and weeds. The methods we use include improving the quality of camera resolution, adjusting aircraft height, adjusting aircraft speed, making good airframes, using 2 axis gimbals and special image processing methods</em></p> <p><strong><em>Keywords : </em></strong><em>Mapping, Unmanned Aerial Vehicle (UAV), Plantation, Remote Sense,&nbsp; Aerial Photo</em></p> Sugeng Sugeng Ramadhan Adi Putra Refinda Fazar Muslim Yogi Septianto ##submission.copyrightStatement## 2019-04-29 2019-04-29 7 1 79 89 10.34010/telekontran.v7i1.1642 Digital Information System and Waifinding https://ojs.unikom.ac.id/index.php/telekontran/article/view/1639 <p><em>Generally new students and new visitors in a building often experience difficulties when searching for a space, especially a building that has a lot of space. As well as having a complex space, both classrooms and staff workspaces. Usually visitors who have just entered the building's environment ask the security information parties or other visitors to provide information on classrooms or staff workspace sought. Another way for visitors to find information on conventional building space is available, but the alternative method requires a lot of time. For this reason, this study was made in the campus building, using NetBeans IDE software applying the closest path search algorithm based on the pixel index value on the map image. The system will display the closest landing map and information on the lecturer room staff room and lecture classrooms and search for lecturer data information. Likewise the search for staff and lecturers by writing their names in the search panel on the touch screen monitor. then pressing the "take me there" button, the system will show the direction to the workspace and provide staff information. To view announcement information, users simply select the announcement menu, then choose the announcement category. With this system, visitors are expected to have no difficulties in finding space and staff and campus information. The purpose of this study is to be able to provide a map of the direction of the building on campus from the position of the system to the classroom and the staff room and lecturer room.
