“…Polutan yang dihasilkan dari sektor transportasi sangat sulit untuk dihindari karena emisi dari kendaraan sebagian besar terjadi pada ketinggian yang sangat rendah seperti contohnya di kota-kota besar [6]. Bahan pencemar yang terutama terdapat didalam emisi gas kendaraan adalah karbon monoksida (CO), berbagai senyawa hidrokarbon, berbagai oksida nitrogen (NOx) dan sulfur (SOx), dan partikulat debu termasuk timbal (Pb) [7]. Pencemaran udara berdampak terhadap kesehatan manusia dan makhluk hidup lainnya.…”

Udara bersih atau udara segar menjadi hal yang diinginkan dalam beraktifitas, baik di dalam ruangan maupun di luar ruangan. Namun, seiring berkembangnya zaman pencemaran udara semakin meningkat. Oleh sebab itu dibuatlah sebuah alat yang bertujuan untuk memonitoring kadar udara. Alat ini digunakan untuk mengetahui kadar Nitrogen Dioksida(NO2), Sulfur Dioksida (SO2) dan Karbon Monoksida (CO). Alat ini menggunakan mikrokontroler Wemos ESP32 Uno sebagai pusat kontrol kerja alat dan modul wifi sebagai kontroler jaringan. Input dari alat ini yaitu sensor MQ135 berfungsi mendeteksi kadar NO2 dan SO2, sensor MQ9 untuk mendeteksi kadar CO. Output alat ini adalah LCD dan WhatsApp berfungsi untuk menampilkan status udara, kadar NO2, SO2 serta CO, menggunakan LED sebagai indikator dan Buzzer sebagai alarm. Berdasarkan hasil pengujian dan analisa menunjukkan bahwa alat bekerja dengan baik merespon setiap perbedaan data sensor yang terdeteksi dan menampilkan status udara, kadar gas pada LCD dan Whatsapp. Hasil tampilan jika dibawah 500 ppm maka kondisi udara baik, jika nilai di antara 500 – 1000 ppm maka kondisi udara tidak baik dan jika berada di atas 1000 ppm maka kondisi udara buruk.

Air pollution due to motor vehicle exhaust emissions is increased. Polluted air harms human health dan the environment. Consequently, it is essential to make a sustained effort to reduce air pollution. The purpose of this research is to investigate the effect of adding aluminum scrap to the exhaust system of a motor vehicle on gas emissions composition. The motor vehicle exhaust system was modified to accommodate aluminum scrap placement. A gas analyzer was utilized to observe exhaust gas composition, such as carbon dioxide, hydrocarbon, and carbon monoxide. Aluminum scrap with different masses was wrapped around the exhaust's inner tube in 50 gr, 70 gr and 90 gr. The engine speed was maintained at 500 rpm throughout the testing process. It was found that the temperature of the outer exhaust tube is in a range of 40 degrees Celsius to 50 degrees Celsius. The results revealed that the most appropriate amount of aluminum scrap was 90 gr n to reduce carbon monoxide, hydrocarbon, and carbon dioxide in an exhausts gas. The surprising outcome was 76.78 % of carbon monoxide content declined, and furthermore hydrocarbon, and carbon dioxide content were deteriorated by 61.63% and 78.37%, respectively.

Designing a fuel-based electric motorcycle frame needs to be modified to be able to place electrical components. Design and simulation of frame design variations are needed to obtain optimal frame strength by having the lowest stress, lowest deformation, and highest safety factor. The research objective is to obtain a frame design with optimal frame strength. The research method uses a comparative method in the form of three frame design variations simulated by Ansys Workbench. The frame simulation uses two types of loads, namely normal loads (146.2 kg) and heavy loads (316.2 kg). The simulation material uses AISI 4130 material. The selected and optimal frame design is the frame with the lowest maximum von Mises stress value and not more than the yield stress, the lowest maximum total deformation, and the highest minimum safety factor and > 2.5. From the research results, it was found that design 2 was the design with the best strength compared to design 1 and design 3. Simulation with normal load (146.2 kg) obtained a maximum von Mises stress of 50.38 MPa, maximum total deformation of 0.036 mm, minimum safety factor of 8.237. While the heavy load simulation (316.2 kg) obtained a maximum von Mises stress of 144.64 MPa, a maximum total deformation of 0.863 mm, a minimum safety factor of 2.869.
