AbstractHumans on earth need social interaction with others. Humans can use more than one language in communication. Thus, the impact that arises when the use of one or more languages is the contact between languages. One obvious form of contact between languages is interference. Interference can occur at all levels of life. As in this study, namely Indonesian Language Interference in Learning PPL Basic Thailand Unhasy Students. This study contains the form of interference that occurs in Thai students who are conducting teaching practices in the classroom. This type of research is descriptive qualitative research that seeks to describe any interference that occurs in the speech of Thai students when teaching practice. Data collection methods in this study are (1) observation techniques, (2) audio-visual recording techniques using CCTV and (3) recording techniques, by recording all data that has been obtained. Whereas the data wetness uses, (1) data triangulation, (2) improvement in perseverance and (3) peer review through discussion. Data analysis techniques in this study are (1) data collection, (2) data reduction, (3) data presentation and (4) conclusions. It can be seen that the interference that occurs includes (1) interference in phonological systems, (2) interference in morphological systems and (3) interference in syntactic systems.

The school principal has been unable to carry out his duties as a supervisor optimally, Objective of this research is to find out why the head of the School is not optimal in carrying out duties as supervis or . Determination of the subject using purposive sampling technique. This study uses a qualitative approach with data collection methods, namely observation, interviews and documentation. Data analysis techniques include data reduction, data presentation and verification / drawing conclusions, while checking the validity of the data is done by extending observations , observation accuracy, and triangulation. The findings in this study indicate that the principal considers the teacher to have professional competence obtained from his education, the principal considers that the implementation of supervision is not so important, and the principal himself does not know about optimal supervision. The conclusion is that the principal has not performed his duties as a supervisor optimally because the principal thinks the teacher already has professional competence obtained from his education so that the implementation of supervision is not so important. The principal should make a class visit to observe the learning process directly, then conduct individual talks to solve the problems faced by the teacher, and the principal programmatically conducts learning simulations for the teacher to observe.
