Bahasa Kerinci is stable yet endangered, according to Indonesia’s Language
Development and Fostering Agency. No one can learn a local language because the
younger generation quit using it. This research seeks to determine Bahasa Kerinci
speakers’ linguistic attitude, its cause, and its extinction using differential equation
models. Quantitative and qualitative methodologies are used for this research.
Familiarity, social engagement, dialogue outside of intimacy, the relationship between
Bahasa Kerinci and other languages, preservation, and skill are the six domains of
language attitude analysis. The research found that teens in Kerinci Regency and
Sungai Penuh City had a neutral to positive language attitude with an average score of
0.599 from all domains. The results also showed that Kerinci Regency teenagers had a
more positive language attitude than Sungai Penuh City teens. The informal teaching of
Bahasa Kerinci and the atmosphere that supports it influence teens’ linguistic attitudes.
Using dynamic mathematical models with three compartments (Bahasa Kerinci’s
monolingual speaker, Bahasa Indonesia’s monolingual speaker, and bilingual speaker)
and linguistic attitudes, Bahasa Kerinci’s extinction was simulated. Questionnaires
determine each parameter’s value, including number of speakers, degree of contact, and
linguistic attitudes. Maple software and the Runge-Kutta-Fehlberg method simulate
numerically. The simulation reveals that linguistic attitude maintains and even increases
bilingualism.
