This is influenced by several factors, such as air density, altitude, and air pressure. Furthermore, the shape of the wings will affect the factors mentioned above. In this experiment, we used a prototype of a different shaped airplane wing to be tested using the LTD device. LTD consist of two parts, the outer part which serve purpose as the source of the smoke, and the inner part that consist of the aircraft wing, fan, room thermometer, and flashlight. This experiment will show the air output whether it is laminar or turbulent. In addition, we will see how much laminar and turbulence affect the effectiveness of the wings of the aircraft being tested. The purpose of this study is to determine how much influence the shape of the aircraft wing has on the turbulence that occurs, then identify which wing causes the minimum turbulence. We used 3 different airplane wing models, namely model A, model B, and model C with each model having a different area. Our results show that the LTD device is able to show differences in turbulence in each model of the airplane wing, and it shows that the LTD device can detect the presence of laminar and turbulence in the airplane wing prototype through the observation by researcher.

In the material of parabolic motion, it is known that 45° is the special angle that produces the farthest distance. The misconception that 45° is the angle that produces the farthest distance has become a reference in learning in various educational institutions to this day. The aim of this research is to identify and prove that the 45° angle is not the elevation angle which results in the farthest distance in a vacuum which ignores the initial position of the thrower. The method used is Data analytics, and compared based on Graphics Analytics using PhET virtual laboratory media. This study will test an elevation angle of 42° : 45° : 48° based on a height of 0 m: 1 m: 2 m. The results of the research will be analyzed based on the functional analyzer approach which is made from equations into function graphs to make it easier for readers to read the data. In this research, it is found that 42° is the farthest distance producer and also gets a travel time that is relatively faster than the 45° angle which we know so far as the special angle that produces the farthest distance in non-vacuum conditions. In this study, it is hoped that the readers will be able to reexamine the earning angle of the furthest distance which is still a misconception in various educational institutions.

The learning process in the 21st century does not only focus on teaching and learning activities in the classroom and explaining theories. There need to be laboratory activities that help provide visuals to students, especially future physics teacher candidates. Various innovations have been made in the development of laboratory activity models. There are still many laboratory activity models that focus on one activity, namely real or virtual. Laboratory activities in the 21st century do not always have to focus on super skills or 4C skills currently in the spotlight and forget about analytical skills and the balance between LOTS and HOTS. This study aims to develop a mixed laboratory activity model that can build 4C skills focused on analytical skills and balance between LOTS-HOTS; in addition, two activities are combined into one, real and virtual. The method used in this research is in the form of Research and Development using the ADDIE model with three meetings in implementation. The results obtained in this study, namely STB-LAB, obtained good model and guide validity results. N-Gain data showed that in the control class, only creative thinking skills were compelling enough, with a value of 59.47. In contrast, in experiment class, only communication skills have an effective enough category with a value of 57.84, but other aspects have an effective category with a value > 76.00. The hypothesis test showed that using STB-LAB could improve students as physics teacher candidate 4C Skills.

Diharapkan dengan pengabdian ini seluruh guru SMP-SMA Pinggir bisa melaksanakan penulisan PTK sebagai karya ilmiah guru nantinya. Sasaran pengabdian ini adalah guru-guru yang terkendala kenaikan pangkatnya karena tidak adanya penelitian sebagai karya ilmiahnya.Disimpulkan bahwa, masih banyak guru-guru yang belum memahami hakikat dari Penelitian Tindakan Kelas (PTK) ini. Hal ini disebabkan oada umumnya guru belum terbiasa menulis PTK, kalaupun ketika guruguru yang telah mengikuti PLPG memang di berikan materi PTK, tapi alokasi yang disedikan tidak memungkinkan mereka untuk dapat menguasai tentang PTK. Salah satu yang dapat dilakukan oleh guru adalah mencontoh laporan PTK yang sudah dibuat oleh guru sebelumnya. Sehingga terkesan hanya kopi paste.

Metode penelitian yang dipergunakan adalah eksperimen. Teknik analisis data menggunakan analisis deskriptif yaitu mengamati dan mencatat hasil pengujian kemudian menyimpulkan dalam bentuk tabel dan grafik. Pengujian torsi dan daya dilakukan pada mesin Vixion New 150 cc tahun 2018 menggunakan dynamometer dan alat ukur buret digunakan untuk pengujian konsumsi bahan bakar. Pengambilan data dilakukan pada putaran 5000 rpm, 6000 rpm, 7000 rpm, 8000 rpm dan 9000 rpm. Hasil pengujian menunjukkan adanya perbedaan daya, torsi dan konsumsi bahan bakar yang dihasilkan oleh kedua coil dan busi. Untuk daya, dan torsi yang dihasilkan coil racing dan busi racing memiliki nilai yang lebih tinggi jika dibandingkan dengan coil standar dan busi standar dan untuk konsumsi bahan bakar coil racing dan busi racing memiliki nilai yang lebih rendah dibandingkan dengan coil standar dan busi standar, yang artinya konsumsi bahan bakar coil racing dan busi racing lebih irit jika dibandingkan dengan coil standar dan busi satandar, sehingga dari penelitian yang sudah dilakukan pada motor Yamaha Vixion New 150 cc dapat disimpulkan ternyata ada kenaikan daya dan torsi yang dihasilkan pada motor yang menggunakan coil racing dan busi racing dan untuk konsumsi bahan bakar terjadi penurunan pada motor yang menggunakan coil racing dan busi racing.

Namun, perlu kita lihat lebih teliti lagi dengan melakukan percobaan-percobaan pada alat dynamometer dan sepeda motor dengan menggunakan variasi angka oktan dan busi koil standar dan racing . Percobaan dilakukan terhadap 3 jenis bahan bakar dengan nilai bilangan oktan yaitu 88, 90 dan 92. Didapat nilai daya tertinggi pada pengujian bilangan oktan 92 dengan busi koil racing sebesar 6.753 kilo watt pada kecepatan putaran mesin 7762.6 rpm dan nilai torsi tertinggi pada pengujian bilangan oktan 92 busi koil racing sebesar 9.072 newton meter. Nilai daya maksimum terendah terjadi pada bilangan oktan 92 busi koil standar sebesar 6.601 kilo watt pada 7725 rpm dan torsi maksimum terendah pada bilangan oktan 88 busi koil standar yaitu sebesar 8.914 newton meter pada 4584.8 rpm . Nilai konsumsi bahan bakar spesifik tertinggi pada...

Z. CV. Z merupakan pabrik daur ulang yang bergerak padapemasakan ulang ban bekas dengan berbagai ukuran yaitu ban ring 750/16, ban ring ukuran 1100/20 dan ban ring 900/20. Penelitian ini menggunakan model penelitian deskriptifstatistik. Analisis yang digunakan yaitu dengan Statistical Process Control (SPC) dan Kaizen. Hasil analisis menunjukkan bahwa pengendendalian kualitas produk masih berada dalam batas kendali.Jenis kerusakan adalah adalah ukuran ban ring 1100/20 dengan jumlah kecacatan sebesar 2,3%, ukuran ban ring 900/20 jumlah kecacatan sebesar 4,4% dan untuk ban ukuran 750/16 sebesar 2,7%. Dari diagram sebab akibat dapat diketahui faktor penyebab kerusakan dari yang paling dominan meliputi mesin, bahan baku, manusia, dan metode. Berdasarkan kaizenmaka rekomendasi untuk mengurangi kec...

The results of the metal plating waste heavy metal that can have a negative impact on the environment, therefore it is necessary for the handling of waste from electroplating/phosphating, through stages such as the neutralization process, purification, precipitation, and separation. Keywords: electroplating, phosphating, the waste.

This study uses a developmental research type with the Thiagarajan 4-D Model which consists of 4 stages, namely, define, design, develop, and disseminate. The research was conducted at PGSD of FKIP, Universitas Riau. The object of this research is the big book of elementary school students developed from the basic competencies in the 2013 curriculum. The products produced are 3 big books with the title Sekolahku, Wisata ke Pantai and Taman Kota. The results of the validation of the three big book titles carried out by experts, the feasibility of the content of the material obtained by the percentage of scores for the title Sekolahku 82.1%; Wisata ke Pantai 82.1%; and Taman Kota 86%. Meanwhile, for the big book language assessment, the percentage for Sekolahku was 79.9%; Wisata ke Pantai 79.7%; and Taman Kota 82.5%. So that the big book learning media is feasible to be tested w...
