Abstract

Dengan berkembangnya teknologi, menambahnya pengguna kendaraan bermotor di Indonesia semakin meningkat. Salah satu alternatif yang sudah tersedia sejak awal era revolusi industri adalah sepeda. Hanya saja dengan tata letak jalan raya di metropolitan Indonesia dengan kontur tanah yang tidak begitu rata menyebabkan banyak pengguna jalan raya yang sudah mempunyai sepeda sekalipun kurang meminati sepeda dari segi keamanan dan keselamatan. Oleh karena itu, untuk menyelesaikan masalah tersebut, digunakan Otomatisasi Transmisi gigi Sepeda, yaitu suatu alat yang dapat membantu pengguna sepeda untuk membantu menggantikan transmisi gigi sesuai dengan elevasi yang dihadapi ataupun berdasarkan tingkat pengendara.
Sistem terdiri dari Cadence Sensor, ESP32, Servo Motor, serta baterai LiFe. Sistem yang terintegrasi dapat mendeteksi ketika pengguna mengeluarkan tenaga yang akhirnya terbuang karena adanya perubahan kemiringan sepeda atau faktor lain yang dapat mempengaruhi banyaknya kayuhan pengendara saat bersepeda. Terdapat Cadence Sensor di dalam sistem ini, Cadence Sensor membaca revolusi pedal per menit (Cadence). Dengan sensor dan data yang di dapatkan dari pola berkendara pengguna, data tersebut diolah pada mikrokontroler ESP32. Hasil output sensor diolah mikrokontroler agar dapat menentukan waktu yang optimal untuk mengganti gigi atau tidak mengganti gigi. Dengan keputusan yang dihasilkan oleh sistem, aktuator yang berupa servo motor akan mengganti gigi pada bagian derailleur belakang sesuai dengan keinginan sistem. Sistem juga memiliki tingkat akurasi keputusan sebesar 77,3% Dengan kata lain, Sistem ini dapat mendeteksi kebutuhan pengguna tanpa harus menggantikan transmisi gigi secara manual, dengan begitu pengguna dapat lebih fokus pada keamanan dan keselamatan berkendara pada jalan raya. Dengan adanya sistem ini, diharapkan pengguna sepeda di kota metropolitan dan lebih percaya diri ketika berkendara menggunakan sepeda.

With the advent of technological innovations, the growth rate of motorized vehicle consumer is surely increasing. One of the alternative of such conundrum has been invented a while ago which is the bicycle. Although with how most Indonesian metropolotian city street infrastucture has uneven contours and street quality which dissuade bicycle rider to use such vehicle as it could endanger their safety and reduce their comfort in riding. Therefore to solve that problem, it could use an Automated Bicycle Gear Transmission, which is a set of device that could help a rider to shift their gear when the need arises, for example an elevated road or slowed cadence.
The integrated system has the ability to detect the power loss that was done by the rider when the terrain, inclination or other factors that could be able to influence the rider’s cadence. This device would need a cadence sensor to be able to detect the amount of the rider’s cadence. Such data would later be calculated by the ESP32 to determine when would be a good time to change the gear automatically. After the decision made by the system, the servo actuator would change the bike’s gear according to such decision. The system also has 77,3% chance of accuracy in actuation. In other way, the system could detect the rider’s need of changing the gear without having the need to fiddle with the shifter themselves, which they could pay a lot more attention towards their own safety when they’re riding out in the open. With such system, it is hoped that a beginner bicycle driver would use the bicycle as one of many alternatives when they traverse in a metropolitan city.
