Abstract

Indonesia adalah salah satu negara yang beriklim tropis. Curah hujan yang tinggi menyebabkan banjir pada sungai yang tidak dapat diprediksi. Bencana banjir yang terjadi nampak tidak ada pencegahan secara efektif serta kurangnya sistem untuk memberikan peringatan sedini mungkin sebelum terjadinya bencana banjir agar kerugian dapat diminimalisir. Pemantauan bencana banjir harus dilakukan di tepi sungai dari hulu ke hilir. Pada lokasi tersebut sering tepi sungai berada di daerah hutan yang kondisi sinyal gsm lemah bahkan tidak ada. Kondisi tersebut menyebabkan sulitnya pengiriman data antar node ews ke penerima. Kesulitan tersebut dapat diatasi dengan menggunakan sebuah modul Lora. Lora mempunyai komunikasi menggunakan gelombang radio 455 Mhz. Gelombang tersebut dapat dipancarkan oleh modul dan dapat diterima oleh modul Lora di Reciver. Sehingga pengiriman data dapat dilakukan tanpa mengadalkan sinyal GSM. Lora juga dapat digunakan untuk pengiriman data menggunakan topologi jaringan seperti star, mesh, dll. Sistem peringatan dini bencana banjir menggunakan Lora didapatkan jarak maksimal komunikasi pada NLOS jarak maksmial komunikasi adalah 520 m dengan nilai RSSI terkecil -128 dan terbesar -147 dBm.

Abstract

The rainfall in the Cilacap region is high, about 80-100mm in October-March. The high rainfall that causes the overflow of river water is unpredictable. The high water discharge is not realized until the river water overflows and causes flooding. Therefore, a river water level monitoring system is needed to detect river overflows early. This tool uses a solar cell as a power supply. The monitoring system is divided into two points of river water level monitoring system with a distance between points for the laboratory scale stage, which is 100 meters. Sensors that measure the height of river flow are ultrasonic sensors. The sensor results are processed by microcontroller and SIM 900 L module to be sent to the database. When the water level is in the Alert level 3, the buzzer will sound as a warning. The ultrasonic sensor test results have a very small error. Sensor 1 has an average error of 0.00023% and ultrasonic sensor 2 has an error of 0.00016%. The system is able to transmit river water level data that can be accessed through the website.

Abstract

Telecommunication Network Tower is a tower made of a series of iron profiles or rectangular or rectangular pipes, or rectangular long pipes intended to accommodate antennas and radio transmitters and receivers of telecommunications and information waves. In principle, BTS towers have the function of connecting network user communication devices to other networks. To support the smooth operation of the network, the building will remain solid and secure for a certain period. Investigation of the feasibility condition of the tower structure is very important to determine the overall condition of the tower structure. The methods used are hammer test, check bolt tightness (torque), measure slope (vertical), grounding, and visual observation. From the results of the test data obtained the average bolt tightness is 432.86 Nm. The tower slope test of 1.90 cm on leg A smaller than 3.6 cm is considered good because it is still within the tolerance limit of the bat slope, the average soil resistance measure smaller than1 ohm used is very good, and the visual physical conditions are very similar, so it can be done Tower in safe and working condition

Abstract

Solar panel systems are widely used to meet energy needs at this time. Solar panels have optimal power for 4 hours, namely 10:00 to 14:00. but this is still said to be not optimal if the angle of the static solar panels does not follow the movement of the sun. This can also be caused by weather factors that are covered in clouds. Previous research conducted by Tri Wahyu Ardianto used mirror reflectors but was not equipped with sensors and data storage. Based on this, to optimize solar panel energy, a flat mirror reflector design for solar panels has been made, equipped with four flat mirror reflectors on each side to form a large square. The solar panel is placed in the middle between the four flat mirrors. In this study, the measurement of electric power was carried out by carrying 3 variable angles for reflector positions, namely 0°, 60°, and 70°. The decision of the three reflector positions is made to find out the ratio of the maximum output power values. This system is also equipped with current, voltage, and light intensity sensors. The results show that the maximum output power of solar panels is shown at the reflector position of 60° with an average power output of 19.70 Watt followed by a reflector position of 70° with an average output power of 19.18 Watt and finally the reflector position is 0° with an average output power value of 14.87 Watt.

Abstract

Aquaponics is an application of a sustainable agricultural system by integrating the cultivation of plants and fish at one time. Water availability in plant commodities and water is optimized in aquaponic cultivation systems. Several parameters that can determine the level of success of cultivating an aquaponic system include water pH, water temperature, TDS, and water level. The process of monitoring and controlling several important parameters in cultivation can be done conventionally, but it is less effective and efficient because the cultivator has to check and measure the parameters every time. Therefore, as time goes by, and technology becomes more sophisticated, a control and monitoring system is designed. several parameters such as water pH, water temperature, TDS, and water level based on the Internet of Things (IoT) to support the success of the aquaponics system by monitoring environmental conditions using a laptop/smartphone at that time. Based on the test results, it was found that aquaponics in an indoor environment is successful - the air conditioner has a water temperature below 250C, the water pH shows 7pH and the average nutrient in the water shows 214.5 ppm. Based on this, kale plants in the stem grow quickly while leaf growth is very stunted. At temperatures smaller than 25 0C pomfret fish only survive for 2 weeks but tilapia fish can survive and not die in these environmental conditions. The length of the tilapia fish for 6 weeks has increased by 5 cm from its original length
