The context is too short.
It can also be "dasar yang disepakati".

= on the basis of what is received

IMO

“as received basis” is a term which is applied to coal and other products such as oil-producing plants. Different types of coal contain different types of moisture, ash and minerals which affect the amount of heat they produce when they are burned. Usually coal is processed before it is burned and the pre-processed state is known as the “as-received basis”. There are different means of classifying coal such as “remnant-moisture basis”, “ash basis” and so on.

“as received basis” here is not referring to the condition something is in when you get it, like “what you see is what you get”, but rather the condition it comes out of the ground in.

Maaf, seharusnya "..Different types of coal contain different amounts of moisture ..."

English term (edited): on as-received basis

Referensi dan penjelasan "as-received" menumpang saja ke penjelasan Ian yang cukup terinci dan menyeluruh.
