Giant green leech (Raksasa hijau) is a species belonging to the family Salifidae. It is a large, green or black, carnivorous leech—not a blood-feeder (hematophage)—that can grow to a length of over 50 cm. Its anterior (front) section is perfectly cylindrical, while the body becomes progressively larger, wider, and flatter toward the posterior (rear) end.
At the anterior end is a white-colored mouth, with a width equal to the diameter of the front of the body. The posterior end houses the anus and is similarly as wide as the diameter of the rear of the body.
The dorsal (upper) surface is entirely dark green—ranging from leaf-green to black—with a glossy appearance and no other color patterns. The ventral (lower) surface is lighter in color, appearing as a brownish-green. The skin is wrinkled, forming dense, elastic folds that allow the body to stretch and elongate.
This species moves forward by extending its anterior end toward a distant point; the middle of the body follows, and the posterior section gradually advances until the entire animal has shifted its position.
These animals do not feed on blood; instead, they swallow their prey whole. They inhabit the ground surface among leaf litter—often at a considerable distance from standing water—in environments that remain damp and dew-laden. This species actively hunts for prey, primarily earthworms.

Hi! This is quite a remarkable find. I have found another similar-looking individual with the one that you found, and has discussed about this in another forum. Take a look and maybe join the discussion at https://inaturalist.ca/people/2573219 if you'd like to.
