The word formation is largely influenced by derivational affixes. These affixes however have certain level orderings called stratum ordering that lead to the formation of new words hierarchically. The study focuses on the investigation of the possible stratum ordering of derivational morphemes in scientific texts and the analysis of how these stratums form polysyllables derivational words. Qualitative research methodology is applied to this study. The data source of this study was taken from http://ijiemjournal.uns.ac.rs/v11/v11-01.html. This journal concerns Industrial Engineering and Management. The intended data are randomly taken from five journals published on Volume 11 | Issue 1 | March 2020 limited to polysyllables of scientific terms. The data were analyzed using the theory of Francis Katamba proposing that the central to lexical morphology is organized in a series of hierarchical strata and also Spencer (1991) supported by Plag and Baayen (2008). This paper concludes in general that the addition of derivational affixes to scientific terms is hierarchically structured based on the theory, such as the placement of strata 1 affixes closer to the root word, the neutrality of stress placement of strata 2 suffixes, and non-netrality of strata 1 suffixes. However, it is also found some inconsistencies in the placement of derivational suffixes in which the second strata are placed closer to the root. This happens when suffix -able is combined with -ity in availability (adjective to noun) or when suffix -ize is combined with -ion to form verb to noun in parameterization. The most formations found is the use of suffixes -ion, -ity for nouns, -ize for verbs, -ive and -able for adjectives.

The current study investigates the representation of UNPAD, which raises the issue of Sundanese textbooks on the UNPAD website. It focuses on how the article entitled "Sundanese Textbooks Still Lacking Attention to Speech Language Level" on the UNPAD website represents the current Sundanese textbooks that are used by the students in the school. The data is taken from the article on UNPAD's website, www.unpad.ac.id. This study used a qualitative research design with the characteristics of a descriptive study. In qualitative research, a single phenomenon of interest is researched before being stated in a purpose statement. The study's findings indicate that the use of Sundanese textbooks is viewed negatively due to a lack of attention to the language's level
