-455-Falewuo (Kebambuan) Glosarium in Society Nias: Ecolinguistic Study

Ecolinguistic is a branch linguistics who studies the role of linguistics in problem ecology and environment. Ecolinguistics is an interdisciplinary study that looks at the link between ecosystems and linguistics. This study involves sociology, anthropology, psychology and political science. The socio-ecological aspects greatly affect the balance, preservation and inheritance of the environment for current and future generations. Falewuo's lexicon, for example Niru, still remains in the memory of the older generation, but the entity has become extinct. The purpose of this research is to maintain local ecological wisdoms that need to be included in the discourse of a healthy and green environment (greenspeak), bearing in mind that the soul (ideological, philosophical, socio-ecological concepts) of the community is imbued with these local wisdoms. There are changes due to the emergence of practical tools made of plastic, aluminum and iron. language because it is rarely used. This study used qualitative methods. The qualitative method is a research method based on existing facts or phenomena that empirically live in the speakers (Sudaryanto, 2015). The theory used is Mbete's ecolinguistic theory. From the research results, it was found that the changes in the lifestyle of the Nias people had changed considerably and did not pay attention to nature as a provider and life. The conclusion of this study is that the pattern of social life has also begun to shift towards individual traits. Environment and language are closely related because every flora and fauna that exists must have the meaning of the wealth of the language-speaking community.

languages of relatives in a geographic environment the focus of studies to find their genetic historical relations. Second, demographic linguistics. , examines certain language communities in an area to describe the quantity of resources (and quality) of the use of languages along with their domains and varieties and registrations (sociolectual and functional lecturing). the structure of the speaking community Fourth, dialinguistic, which focuses its studies on the range of dialects and languages used by the language community, including in new habitats or migration pockets with their ecological dynamics Fifth, dialectology, studying and mapping internal variations in the language system Sixth, philology, examines and explores the potential of written culture and tradition, its propek, the meaningful relation to the study and / or the fading of the culture, and local writing traditions. Seventh, prescriptive linguistics, examines the viability of language in certain areas in certain areas, standardization of written and spoken language, standardization of grammar (as local content which does require certainty of standard, normative and pedagogical language). Eighth, glotopolytics, also studies and empowers institutions for handling language problems (especially in the era of regional autonomy, special autonomy, and assistance to offices and / or language centers). Ninth, ethnolinguistics, anthropological linguistics or cultural linguistics (cultural linguistics) which dissect selective use of language, way, style, mindset and imagination (Palmer, 1996, in relation to patterns of language use, ritual languages. , the creation of advertising discourse based on local languages. Tenth, typology, examines the degree of universality and uniqueness of languages. Of the ten studies of language ecology above, this research is closely related to ecolinguistics.

LITERATURE REVIEW
Ecolinguistics is a scientific discipline that studies environment and language. Ecolinguistics is an interdisciplinary language science, side by side ecology and linguistics (Mbete, 2008: 1). Based on this, language is closely related to its own environment. The language can be lost or wiped out if the ecology that supports it is destroyed too. There is a real relationship regarding various changes in the physical environment to language and vice versa. In his writing Language and Environment, Mühlhäusler (p. 3) mentions, there are four that make possible the relationship between language and environment. All of them are different subjects of linguistic study at one time, or at another. The four relationships are (1) Language is independent and self-contained (Chomsky, Cognitive Linguistics); (2) Language is constructed by the world (Marr); (3) The world is constructed by language (structuralism and post structuralism); Ecolinguistics is an interdisciplinary study that studies the relationship between ecosystems and linguistics. This study was introduced by Einar Haugan in 1972. Various socio-ecological changes greatly affect the use of language, as well as changes in values and culture in a society. These changes are recorded and clearly reflected at the lexical level in the language used.
By believing in the concept of signs, the peculiarities of approaching natural events can be studied linguistically. Linguistics has a branch of science related to nature, namely ecolinguistics. This branch of linguistics was pioneered by Einar Haugen around 1972 with a study of the interaction between created language and the environment. The term Haugen introduced is language ecology. Developments around 1990, ecolinguistics became a new paradigm in language studies which involved not only the social context but also the ecological context.

RESEARCH METHODS
Qualitative methods in used in this research. Qualitative methods are research that uses data based on existing facts or phenomena that empirically live in speakers (Sudaryanto, 2015). Overall data will be obtained using the watch and note method. This data is analyzed by means of the split method which is part of the language itself which is the determining tool. This is the right method for analyzing language (Sudaryanto, 2015: 18). This research begins with data collection. Data collection was carried out by observation and interviews. In the observation method, data is recorded and recorded. In the interview method, the informants were asked what bamboo vocabulary (falewuo) in Nias society they still use and which are hardly used. The data sources in this study were 4 native speakers of Nias who live in South Nias, Amorosa Village, Lolomatua District. The informants interviewed were men and women aged 20-44 years.

RESULTS AND DISCUSSION
In the Nias language, problems also occur due to displacement of the use of natural materials that are used by the community to meet their needs. This shift in the use of these tools resulted in the use of the Nias language vocabulary being rare and almost extinct among the people who spoke the language. This change is due to the emergence of new tools that are more practical but do not think about nature and can cause environmental damage such as the emergence of materials made of plastics, atoms, iron and mercury. This can damage the environment and can also damage the language, namely by losing the Nias vocabulary about the name of the previous tool because it is not used. As the younger generation of language successors, of course they don't know the vocabulary because they have never heard and used the vocabulary. So that the vocabulary will gradually be lost or destroyed.

Ecolinguistics is a scientific discipline that studies environment and language. Ecolinguistics is an interdisciplinary language science, juxtaposing ecology and linguistics (Meko, Aron 2008: 1). Based on this, language is closely related to its own environment. The language can be lost or wiped out if the ecology that supports it is destroyed too. This

Rahmawati, Dwi Widayati
-460-bamboo vocabulary could become extinct due to not using bamboo materials, which are the rich vocabulary of the Nias language.

CONCLUSION
The use of words or vocabulary derived from bamboo in Nias society has experienced a deterioration because the tools used in everyday life, both in household appliances and agricultural tools, have been replaced by tools that are more modern and more practical. The Nias people, who are recognized as people who live from nature and use nature to make ends meet and are friendly with nature, have changed to a more practical community in fulfilling their needs. This reluctance in the langurish vocabulary will result in a diminished list of Nias language vocabulary that is used slowly. Changes like this will have a negative impact on the preservation of Nias language in the future. The use of natural tools is considered irrelevant.
