"Universitas Indonesia sebagai salah satu kampus yang menyediakan berbagai macam moda transportasi bagi pengunjug kampus, salah satunya dengan menyediakan sarana transportasi sepeda Melakukan penelitian transportasi sepeda di kampus UI ini diperlukan untuk mengetahui faktor-faktor apa saja yang mempengaruhi keinginan bagi civitas akademika untuk menggunakan moda transportasi sepeda serta ketersediaan infrastruktur transportasi sepeda.. Penelitian ini menggunakan survey pengamatan langsung dan menggunakan kuisioner tertutup yang ditujukan kepada civitas akademika Universitas Indonesia. Menganalisis data dengan metode statistik deskriptif dan statistic non- parametrik, yaitu mengetahui korelasi dan regresi linier. Hasil analisis pada penilaian infrastruktur transportasi sepeda menunjukkan bahwa variabel fasilitas yang paling berpengaruh kuat. Sedangkan bagi keinginan untuk bersepeda, variabel kehandalan merupakan variabel yang paling berpengaruh kuat.. Kata kunci: Infrastruktur, transportasi sepeda, metode statistik deskriptif......University of Indonesia as one of the campus that provides a wide variety of modes of transportation for campus visitors, one of them by providing bicycle transportation facilities A bicycle transportation research in UI campus is needed to determine the factors that influence the availability of bicycle transportation infrastructure for the academic community and the desire to use the bicycle transportation modes. This study uses survey and direct observation using the enclosed questionnaire addressed to the academic community of the University Indonesia. Analyzing the data with descriptive statistical and non-parametrical statistic methods , which determine the correlation and linear regression . The results of the analysis on bicycle transportation infrastructure assessment showed that the most influential variable powerful facilities. While the desire for cycling , reliability variable is the variable that most strongly influences. Keywords : Infrastructure,bicycle transportation,descriptive statistics method"

"Sepeda tiga roda merupakan perkembangan dari sepeda roda dua dengan kestabilan dan kenyamanan yang lebih baik. Sepeda tiga roda memiliki dua konfigurasi, yaitu dua roda di depan dan dua roda di belakang. Skripsi ini membahas tentang perancangan sepeda tiga roda khususnya rangka dua roda di bagian depan. Rangka tersebut dirancang menggunakan perangkat lunak Autodesk Inventor Professional 2023 Student Version. Sepeda tiga roda disimulasikan dengan perangkat lunak yang sama melakukan gerakan kritis di tikungan pada kondisi stabil di berbagai kondisi kecepatan dan radius putar. Dari hasil simulasi ditemukan dua fenomena tergelincirnya sepeda tersebut. Kedua fenomena tersebut diawali dari roda belakang tergelincir. Kemudian terjadi perubahan arah stabilitas ke arah luar mengakibatkan sepeda terbalik atau ke arah dalam mengakibatkan dua roda depan tergelincir. Fenomena pada roda belakang dianalisis dengan tujuan untuk mengontrol roda belakang. Analisis dilakukan secara eksak dengan menyajikan teori stabilitas untuk sepeda tiga roda di tikungan berdasarkan teori stabilitas pada kendaraan roda dua. Dari hasil perhitungan menunjukkan gaya gangguan  pada roda belakang lebih besar dibandingkan dengan gaya lateral resistensi. Sepeda tiga roda terjatuh akibat dari slip pada roda belakang.......A three-wheeled bicycle is a development of a two-wheeled bicycle with better stability and comfort. A three-wheeled bicycle has two configurations, two wheels at the front and two wheels at the rear. This thesis discusses the design of a three-wheeled bicycle, especially the two-wheel frame at the front. The frame is designed using Autodesk Inventor Professional 2023 Student Version software. The three-wheeled bicycle is simulated with the same software performing critical movements in a corner at steady state under various conditions of speed and turning radius. From the simulation results, two slipping phenomena were found. Both phenomena started with the rear wheel slipping. Then there is a change in the direction of stability outward resulting in the bicycle overturning or inward resulting in two front wheels slipping. The phenomenon on the rear wheel is analyzed with the aim of controlling the rear wheel. The analysis is done in an exact way by presenting a stability theory for a three-wheeled bicycle in a corner based on the stability theory of two-wheeled vehicles. The calculation results show that the disturbance force on the rear wheel is greater than the lateral resistance force. The three-wheeled bicycle crashed due to the slip of the rear wheel."

"Perilaku berkendara aman(safety riding) merupakan bagian dari budaya keselamatan. Terdapat dua faktor yang mempengaruhi perilaku aman berkendara (safety riding), yaitu faktor internal dan faktor eksternal. Faktor internal merupakan karakteristik orang yang bersangkutan yang bersifat bawaan yang meliputi pengetahuan, motivasi, dan sikap sedangkan faktor eksternal adalah lingkungan yang meliputi penggunaan alat pelindung diri, kondisi kendaraan, kondisi jalan, dan fasilitas rambu dan marka jalan. Desain peneltian ini menggunakan penelitian kuantitatif dengan desain cross sectional. Hasil penelitian ini ingin menunjukkan gambaran perilaku aman berkendara pada pengandara ojek di Universitas Indonesia, sedangkan hasil yang didapat untuk melihat adakah hubungan antara faktor internal dengan perilaku dan faktor eksternal dengan perilaku adalah terdapatnya hubungan antara pengetahuan yang bermakna antara pengetahuan dengan perilaku aman berkendara, terdapatnya hubungan yang bermakna antara motivasi dengan perilaku aman berkendara, terdapatnya hubungan yang bermakna antara sikap dengan perilaku aman berkendara, terdapatnya hubungan yang bermakna antara penggunaan alat pelindung diri dengan perilaku aman berkendara, dan terdapatnya hubungan yang bermakna antara kondisi kendaran dengan perilaku berkendara aman. ......Safe riding behavior is a part of the culture of safety. There are two factors that affect safey riding behavior, the internal factors and external factors. Internal factors are those characteristics that are innate in question includes the use of knowledge, motivation, and attitude while the external factors is the environment such as use of personal protective equipment, vehicle condition, road conditions, and facility signs and road markings. The design of this research using quantitave research with cross sectional design. The result of this study to demonstrate safe riding behavior pictures of ojek at the University of Indonesia, while the result obtained to see is there a relationship between internal factors and external factors to the behavior with the behavior is the presence of a significant relationship between knowledge of safe riding behavior, motivation of safe riding behavior, attitude of safe riding behavior, personal protective equipment of safe riding behavior, vehicle condition of safe riding bahavior, road condition of safe riding behavior, and facility signs and road markings of safe riding behavior."

"The purpose of this paper is to evaluate the ergonomics aspects of the first prototype of a folding bike designed by the Department of Mechanical Engineering, University of Indonesia (DME UI) in a virtual environment. Posture Evaluation Index (PEI) is used as an analysis approach that integrates the results of three methods: Low Back Analysis (LBA), Ovako Working Posture Analysis System (OWAS), and Rapid Upper Limb Assessment (RULA). The determine the optimal design configuration of a folding bicycle based from an ergonomics perspective. For male and female riders, the optimal configuration is obtained when the height of the handlebar is 32 cm and the height of the saddle is 83 cm. This study proved that a virtual environment could strengthen the ergonomics evaluation, especially in posture condition exploration."
