Abstract
Sektor transportasi menjadi salah satu konsumen energi yang terbesar di dunia. Kereta api yang secara khusus kereta api diesel-elektrik menghadapi tantangan dalam pengurangan konsumsi bahan bakar untuk meningkatkan performansi. Salah satu solusi yang dapat menyelesaikan permasalahan tersebut adalah dengan menggunakan sistem pengereman regeneratif yang merupakan sistem pengereman yang dapat menghasilkan arus balik yang kemudian disimpan pada baterai (ESD). Permasalahan tersebut dapat diselesaikan dengan menggunakan aturan berdasarkan nilai SOC baterai yaitu terdiri dari skema kontrol satu, dua, dan tiga. Skema kontrol satu menjadi skema kontrol yang sederhana karena tidak melibatkan pola operasi kereta api, namun hanya mempertimbangkan discharge limit dan charge limit, sedangkan pada skema kontrol dua terdapat mode A, mode B, dan mode C yang ketiga mode tersebut bergantung pada pola operasi kereta api yaitu power running, coasting, dan regeneration. Skema kontrol tiga pada dasarnya sama dengan skema kontrol dua, namun ada penambahan mode D dan mode E yang kedua mode tersebut berlaku ketika kereta api berada pada kecepatan di bawah 10 km/jam. Hasil perancangan sistem pengereman regeneratif dengan ESD menghasilkan gain SOC sebesar 0.0002%/N. Pengurangan konsumsi bahan bakar yang diberikan pada skema kontrol 3 memiliki rata – rata sebesar 38% terhadap konsumsi bahan bakar yang tanpa menggunakan baterai atau skema kontrol. Skema kontrol 1, skema kontrol 2, dan skema kontrol 3 memberikan penurunan konsumsi bahan bakar sebesar 37.79%, 38.09%, dan 38.17%.

The transportation sector has been one of the largest fuel consumers in the world. As one of important comercial transportation, diesel-electric train has challenged to decrease diesel fuel consumption to improve the performance. Regenerative braking with battery, such as Energy Storage Device (ESD), is applied to answer this challenge. Regenerative braking is a system which can produce back- current and save the energy to the battery. The problem can be solved by using control scheme based on SOC battery which has three control scheme. First, control one is one of simplest scheme, because it just considered the value of discharge limit and charge limit. Second, control two is the charging or discharging region which was divided into three modes according to the SOC and train speed, there are three mode in control two, they are mode A, mode B, and mode C. Third, control three is the same as control two, but in control three mode D and mode E were added in the low-speed range (10 km/hour). The result of design regenerative braking using ESD giving a gain is 0.0002%/N. Decreasing fuel consumption based on simulation using four study case is 38% to fuel consumption which not using control scheme or battery (ESD). Control scheme 1, control scheme 2, and control scheme 3 provide decreasing fuel consumption is 37.79%, 38.09%, and 38.17%.
