ASPEK EPISTEMOLOGI FILSAFAT HUKUM INDONESIA

Abstract Many people say that the implementation of law in Indonesia has been on the track, nonetheless, it is only the way of putting into effect that is not wise enough. From the point of view of the aspect of onthology of philosophy, the application of law in Indonesia is having no problem so far. On the other hand, the problem is in its epistemology. The duty of philosophy of law is to give explanation of such phenomenon. The problem is therefore laid down in epistemology, it is wise to use the school that talks a lot about epistemology of law. Furthermore, Indonesia is a pluralistic society, for that reason, the choice to use the Modern Natural Law as its approach is considered to be as one of the alternative, for the school itself is emphasizing upon the epistemology of law as well as the custom law which as the characteristic of pluralism of Indonesia. The study of epistemology of philosophy of law in Indonesia, with the approach through the Modern Natural Law toward custom law of Indonesia is supported by the legal studies progressively that may explain the phenomenon of the confused and depraved enforcement of law in Indonesia.
