Batak Toba handwriting is a family of Batak handwriting and became Indonesia's cultural heritage. Batak Toba handwriting was not used for everyday purposes, but one is used to write “pustaha” scripts which contain mostly shamanism and in 1852 began to be destroyed, so it needs to be preserved. Batak Toba script which contained in an obsoleted manuscript or other print media can be obtained using image processing techniques. This study implements a hybrid method of level sets and skeletonisation. Level set method is used to detect the contours of the Batak Toba script and the skeletonisation is used to process thinning, thus obtained from the Toba Batak alphabet characters that shaped the image of the manuscript. Through this research is expected to contribute in expansion of the implementation of method in image processing, thus Batak Toba script information can be preserved
