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.

research aims to determine the effect of simple modeling in learning physics for engineering students. The sample of this study were all 1st semester engineering students at the Medan Area University are 36. The research method used was the ex post facto method, by not providing treatment but directly conducting related evaluations. Engineering students' abilities in learning physics can be helped with simple modeling. Data analysis technique used is by regression analysis. From the results of the analysis it was found that Freghitung= 4.382 and Freg-table = 4.230 (Freg-count >Freg-table), so the conclusion of this study is that there is a very large the effect of simple modeling learning physics for engineering students at the University of Medan Area.

The 2022 world cup is one of the much-awaited world events, especially for men. Even though there are some engineering students who are female, they are still dominated by men. The program to watch the world cup ball, whose broadcast time is more often at night or early in the morning, makes engineering students watching drowsy and unfit due to lack of sleep. This has an impact on the enthusiasm for learning in class which makes engineering students' motivation to study decrease.Data analysis technique used is by regression analysis. From the results of the analysis it was found that Freghitung= 4.282 and Freg-table = 4.130 (Freg-count Freg-table), sample of 36 engineering students in physic class was taken so the conclusion of this study is that there is a very large influence decreased enthusiasm for learning during the world cup for engineering students at the University of Medan Area.

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)

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.

Gerakan pelestarian lingkungan di hutan kanal Kecamatan Medan Johor yang dalam beberapa hari lalu dilakukan oleh Dosen Fakultas Teknik Universitas Medan Area. Pelestarian lingkungan saat ini telah berkembang dan menjalar di Indonesia sebagai upaya penyelamatan lingkungan. Mengingat pesatnya penduduk dan masih rendahnya kesadaran untuk menjaga lingkungan sehingga menimbulkan berbagai permasalahan lingkungan. Untuk memperbaiki kualitas lingkungan hidup maka perlu diadakan beberapa upaya pelestarian lingkungan hidup bekerjasama antara Fakultas Teknik Universitas Medan Area dalam hal ini diwakili Dosen dan mahasiswa bersama masyarakat setempat. Kegiatan ini bertujuan untuk membantu menangani permasalahan lingkungan yang terjadi, memberikan motivasi dan contoh nyata melalui upaya pelestarian lingkungan yang diterapkkan di lingkungan hutan kanal agar mahasiswa memiliki kepekaan, rasa cinta dan perasaan memiliki untuk bersama mengelola serta menjaga kelestarian lingkungan disekitanya. Kegiatan pelestarian lingkungan ini menggunakan metode deskriptif, melalui suatu tindakan nyata dalam upaya pelestarian seperti penanaman bibit pohon, pengadaan tempat sampah dan kerja bakti pembersihan lingkungan di hutan kanal. Kesimpulannya bahwa kegiatan ini dapat terselenggara secara baik dan lancar, hal ini tidak terlepas dari partisipasi dan dukungan berbagai pihak didalamnya. Tidak hanya itu, upaya pelestarian lingkungan hidup yang dilakukan pada lingkungan hutan kanal memberikan manfaat bagi mahasiswa maupun para dosen dan masyarakat setempat. Selain lingkungan hutan kanal menjadi bersih dan sehat, mereka termotivasi untuk melestarikan lingkungan hidup sekalipun dengan hanya menanam pepohonan, membuang sampah pada tempatnya serta gotong royong membersihkan lingkungan disekitarnya.

The development of potato nanocarbon as an electrode from potatoes for supercapacitors will answer the energy needs that are needed and are continuously researched. This research was conducted in the laboratory by giving marinade treatment to potatoes and measured repeatedly and testing was carried out to determine the extent of the carbon content so that potatoes are very good to be used as electrodes with electroplating method. The results obtained were 0.8 grams of potatoes with a very high conductivity increase to 0.97 m S. The result TEM 160 nm after treatment an average size of 100 nm successfully coated on the surface of the particles. FTIR shows a wavelength of 3282.48 cm due to the width of potato absorption and overlapping with the C-H-O group. AAS shows the adsorption capacity of modified potato on metals occurs in the pH range 4.5-5.5. Analysis of potatoes to be made as electrodes with two positive and negative pieces showed better dispersion stability. The electrodes are made and have been tested using a smartphone. The acid in the potato forms a chemical reaction with zinc and copper and when electrons flow from one material to another energy is released.
