Abstract

Musim hujan di Desember 2022 dengan identitas curah hujan yang deras dan frekuensi yang banyak. Hal ini berdampak pada terhambatnya mobilitas mahasiswa teknik untuk pergi dan pulang kuliah. Udaranya yang dingin menjadikan mahasiswa teknik mengantuk dan seringnya kena hujan menjadikan kondisi kurang fit. Hal inilah yang membuat semangat bekajar mahaiswa teknik di kelas fisika dasar menurun. Teknik analisis data yang digunakan adalah dengan analisis regresi. Dari hasil analisis diketahui bahwa Freghitung= 4,282 dan Freg-tabel = 4,130 (Freg-hitung > Freg-tabel), diambil sampel 36 mahasiswa teknik di kelas fisika dasar sehingga kesimpulan dari penelitian ini adalah terdapat sangat besar pengaruhnya terhadap penurunan semangat belajar selama musim hujan desember 2022 bagi mahasiswa teknik Universitas Medan Area.

Abstract

The superstructure is all components that are above the ground. The function of the superstructure is as a support for the building with an upward elongated shape, such as frames, trusses, beams, and columns. The column is a vertical compression member of the structural frame that carries the load from the beam. The construction of this warehouse is located in Tanjung Morawa using IWF steel columns. In this study, the strength of the steel columns was analyzed by modeling using SAP 2000 V.14 and manually calculated on the F portal using the LRFD (Load and Resistance Factor Design) method. The research method uses primary data, namely direct field observations in the form of interviews, and secondary data, namely data taken from the contractor in the form of pictures or from books, previous research, and so on. Based on the results of structural modeling using SAP 2000 V.14, it was concluded that the building is safe; on manual analysis on the F portal, it can be concluded that the steel columns WF-300×150×9×13 and WF-350×175×7×11 are capable of carrying factored compressive loads.

Abstract

Cofferdam is a building in the form of earth, stone, concrete or masonry filling and holds water, prevents flooding, provides irrigation. The building has many functions such as for agriculture, power generation, and tourist attractions. Cofferdam will also be very helpful in flood control which will control flood water so that it will not overflow excessively which endangers the surrounding community. Besides having great benefits. If the cofferdam collapses (broken) it will cause flash floods that result in casualties. Therefore the cofferdam must be designed safely and technically feasible. The research approach used in this study is a quantitative approach using the 2012 GEO-SLOPE program. The conclusions from the analysis of slope seepage and seepage stability are the Critical Safety Factors for cofferdam stability according to the results of the analysis after running SLOPE/W are 1.711 & 1.512 because it is higher than 1.5 (SNI 8460:2017 Geotechnical Requirements Design, This means that the stability of the cofferdam is safe. The modeling results show that the seepage discharge is 1.81x10-7 m3/s = 1.81x10-4 liters/sec = 15.64 liters/day which is smaller than the maximum allowable discharge of 50 liters/day. So it can be concluded that the seepage discharge is safe.

Abstract

This research aims to see development of chitosan and nanodot as chemosensor for contact oil damage at magnetic fields on electric current in solar cell based on the results of 20 experiments. It can be concluded that for each equal increase in the magnetic field on a straight wire, the result is 0.25 T. For every constant increase in the strength of the electric current in the solar panel, the magnetic field also increases15 . The same data is obtained for the magnetic field of straight wire and circular wire because the magnitude of phi is neglected, because only phi is the differentiator.The greater the magnetic field, the greater the electric current in the solar cell and vice versa. This relationship is a straight line (linear)

Abstract

The research aims to  Study development of chitosan and nanodot as chemosensor for contact oil damage of rising electricity costs at home against leakage currents and current theft. This study it can be concluded that the leakage current with applicable experiments in the field is to unplug all equipment connections to the plug, turn off all switches, record the meter on the KWh meter, leave it for 2 hours, record the KWh meter again, compare the first record with the second record, if there is a difference value between the first recording and the second recording then the leakage current is proven to occur.

Abstract

Photovoltaic (PV) installations and wind turbines that are installed on the rooftops of buildings need to be protected because the layout is in a high position and there is a risk of being struck by lightning. Therefore, a more effective protection system is designed to anticipate electronic damage and fire on all materials in the distribution network, especially the addition of PV and wind turbine installations on building roofs. The purpose of this study is to simulate a lightning protection system on the distribution network and the results of on-grid PV energy conversion using electrical transient analyzer program (ETAP) software. Feeder relay delay times and cascade coordination patterns between outgoing and incoming relays do not overlap. the delay time of the relay working on the feeder is 0.31 s and the coordination pattern of the outgoing relay and incoming relay does not touch each other, so the delay time for the incoming relay is 2.73 s. Then testing the results of PV energy conversion connected to the grid using MATLAB Simulink monitoring obtained data reaching 1.600 Wp at peak power with sun conditions parallel to the PV installation layout.

Abstract

The North Sumatra region is an area with the potential for earthquakes originating from volcanic and oceanic eruptions which have resulted in many fatalities. Therefore, through the application of automatic monitoring and control system technology connected to the internet of things (IoTs), it is the right solution to provide efforts to increase security for residents of the house to always be vigilant. The security enhancement method referred to in this study is a home security system protection system by anticipating earthquakes. The advantage of this tool is that it applies a notification security system method with a sensitivity sensor which is automatically sent via email and sonor buzzer which also acts as sound vibrations due to an earthquake. The test results show that when a vibration occurs, the system will send a short email message to the user's smartphone so that the user will receive an email in the form of a warning message that the state of the house has an earthquake and the light-emitting diode (LED) interrupts and the buzzer is also on so that the alarm sounds which has been integrated into IoT. Then an integrated security monitoring system using the web can be monitored in real time.

Abstract

Traffic accidents are something that every road user wants to avoid, but sometimes these traffic accidents occur suddenly because of poor road infrastructure or due to negligence of the road users themselves. At present there are widespread accidents in the traffic system, this is caused by many factors, one of which is the arrangement of lights and the distance between vehicles on the highway. The number of traffic accidents in Indonesia has increased every year. The number of traffic accidents in Indonesia is in line with the increasing number of motorized vehicles. Good lighting and distance allow people who drive to see objects that are done clearly, quickly and without unnecessary effort, especially adequate lighting gives the impression of a better appearance and a refreshing environment. Good lighting and distance can also provide higher efficiency, can increase productivity and reduce visual difficulties and pressure when driving. Conversely, poor lighting and distance will result in a high level of traffic accidents.
