The shape and size of amplang might vary, from traditional elongated "tiger nail" shape (hence also known in its other name kuku macan), dice-shaped to pingpong ball size and shape, and the color is ranged from yellow to light brown.
In Indonesia, amplang is traditionally associated with Samarinda, the capital city of East Kalimantan, since the amplang cracker home industry has thrived in the city since the 1970s. Traditionally amplang was made from ikan pipih or ikan belida (Notopterus chitala), however since this freshwater fish has become scarce, amplang maker has replaced them with ikan tenggiri (wahoo) or gabus (snakehead). From Samarinda, the popularity of this savoury fish cracker spread to other cities in the Borneo island, such as Balikpapan, Banjarmasin, Pontianak, and even to neighbouring Sabah in Malaysia.
Amplang is often sought as oleh-oleh (foodstuff gift or souvenir) by those who visited East Kalimantan. Today, amplang made by home industries in Kalimantan has been widely distributed, available in marketplaces and supermarkets in Indonesian cities, such as Jakarta, Bandung, Surabaya, and Medan.
Today, the entrepreneurs of amplang in East Kalimantan not only produce the snack in the taste of fish, but also in other different flavours, such as crab and seaweed. Nevertheless, the original amplang kuku macan remains as the most popular one.
