This study aimed to develop conceptual frameworks on how to teach STEM concepts in a Bahasa Indonesia subject as integrated learning. This study used a mixed-methods research design that consisted of a document analysis, a survey, and a systematic review. To address the aims of this study, we first determined the STEM concepts on basic competencies of a Bahasa Indonesia subject of Grades 1–3 at elementary school level in the curriculum 2013; the recommended teaching and learning strategies in learning STEM concepts integrated into a Bahasa Indonesia subject of Grades 1–3 at elementary school in the curriculum 2013; and the first proposed conceptual frameworks on how to teach STEM concepts in a Bahasa Indonesia subject as an integrated learning in Grades 1–3 at elementary school level in the curriculum 2013 based on systematic review. The results showed that the conceptual frameworks on how to teach science concepts in a Bahasa Indonesia subject as integrated learning in Grades 1–3 at elementary school level in the curriculum 2013 consisted of Bahasa Indonesia as the main goal and science concepts as an approach to address goals, and recommends it be taught using reading. The conceptual framework on how to teach technology concepts in a Bahasa Indonesia subject as an integrated learning in Grades 1–3 at elementary school level in the curriculum 2013 consisted of Bahasa Indonesia as the main goal and technology concepts as an approach to address goals, and recommends that it be taught using reading. These findings will be useful to Indonesian teachers and teachers in other countries that have integrated science or STEM concepts in the language subject in their curricula as integrated learning or will use integrated learning in their future curricula to contribute to sustainability education.

Objective: This research aims to map the trends in lecturer productivity research through VOSViewer-based bibliometric analysis. Theoretical Framework: This research explains the data analysis on the topic of lecturer productivity and its development using mapping tools on VOSViewer over five years. (2019–2024). Method: This method uses qualitative descriptive analysis to illustrate the performance of bibliometric analysis in forming a network visualization of the chosen theme. Results and Discussion: From the research results over five years (2019–2024), 1000 relevant published journals were found and classified into four clusters according to their publication years. Then, through the classification of journal data, a total of 66 articles published on the theme of lecturer productivity from 2019 to 2024 were identified. From the search results, there are 10 articles with the most or highest citations. It can be concluded that lecturer productivity is a field that can be combined with other fields to be studied. Research Implications: In the era of the Industrial Revolution 4.0, bibliometric analysis is necessary to visually display mapping tools, especially in the education sector. The VOSviewer software application serves as a mapping tool to discover new items or trends, keywords, and the evolution process of the frequency of specific themes in research to obtain various information about scientific developments. Originality/Value: This analysis step is used to facilitate first-time users in accessing and utilizing VOSViewer. This research explains the data analysis on the topic of lecturer productivity and its development using mapping tools on VOSViewer over five years. (2019–2024). Thus, this research is expected to serve as a resource for researchers conducting studies and determining research titles.

The lexicon of biota in the rice field ecosystem is important and interesting to study. This paper aims to describe the form, function, and survival of the flora and fauna lexicon in the rice field ecosystem in the cultural context of the Sumur District, Pandeglang Regency, Banten Province. This paper utilizes the insights of ecolinguistic theory. Data collection was carried out using two techniques, namely (1) observation to obtain data on the form of the lexicon and (2) interviews with informants spread over seven villages to obtain data on the form, function, and persistence of the lexicon. The data analysis methods used are the translational equivalent method and the referential equivalent method. The data analysis technique used is the determining element sorting technique in the form of translational sorting power and referential sorting power. This paper has urgency as a form of documenting local culture and language that is beneficial for environmental or ecosystem conservation. The results of this study indicate that there is a rich flora and fauna ecolexicon which is expressed in Sundanese lingual units. Grammatically, the ecolexicon is in the form of words and phrases. However, the survival of the eco-collection has shifted due to changes in farming patterns and people's living culture.
