verse are joined in a rhyme. Writing couplets is important to dig understanding about both indications of structures in English poems alongside students’ creative imaginations. Structuralism is a perspective that underlines analysis of structures in English language, especially through English literary works. It is also known that structure in English language is meant to be universal rather than particular. Through an exploratory approach within qualitative research, this manuscript underscores structuralism as a way to identify aspects of literature regarding training of writing couplets. Couplet is a work that pays attention to pouring imaginations from the authors’ mind towards a structured sense of lyrical poem. Though the ideas come from various authors’ imaginations, this kind of literature and its writing process may still open to various possibilities in advance. In conclusion, the training of writing couplets is essential not only to give knowledge about patterns of poems in English literature, but also to get it in line with students’ everyday experience and imaginations.

Abstract:This article exposes the crucial points of narratology to expand knowledge of everyday life. This writing is based on community service done to elementary students in Wisma Penjaringan Sari, Rungkut, Surabaya from 2023 to…
o 2024. Narratology mainly emphasizes matters of narrative structures indicated through perceptions of the cultural world as supported by Tzvetan Todorov. Everyday life is understood as reflections of complex actualizations of plural identities in the sense of the living world. Through explorative approach in qualitative research, this paper digs more understanding of everyday life as stories of experience and taste of the people. Putting focus on narrations of the people, the analysis accentuates more into knowledge of everyday life as a never-ending process. It is a continuous understanding being underlined through meanings of individual experience in everyday life. Furthermore, narrative structures include matters of other individuals as otherness. In conclusion, narratology is significant in expanding knowledge of everyday life especially in widening perspectives of otherness through understanding of own self.

Wisma Penjaringan Sari, Rungkut, Surabaya from 2023 to 2024. Children's creativity has the potential to promote knowledge of individuals, societies, and cultures in everyday life as explained by Mihaly Csikszentmihalyi. One of the ways to improve creativity is writing short stories to explore their understanding of surroundings altogether with to uplift their language skills. Through explorative approach in qualitative research, this paper emphasizes writing short stories as a means to build children’s awareness of their potentials, surroundings, and imaginations. Those aspects are needed to cultivate the growth of knowledge to face both formal and informal education. Moreover, ethical aspects could be widened so that children could always appreciate anything that they had, have, and will have. In conclusion, writing short stories for children is crucial to elevate their creativity in formal education and usual everyday life.

duct food self-sufficiency, one of which is by utilizing the yard for the cultivation of catfish budikdamber method based on the development of alternative feed. From this program, people of Caturtunggal Urban Village can use the narrow land of their homes for catfish cultivation to realize food security, as well as provide alternative solutions for the development of cheap, quality, and environmentally friendly feed. Based on the results of the evaluation, the community stated that the use of alternative feed is very useful to maintain the quality of aquaculture and reduce mortality, although there is a lack of catfish growth and a lower appetite than catfish fed. In the future, there need to be further studies on the composition of alternative feed that is environmentally friendly and increases the growth of catfish quickly. This program is a prefix program that is planned to run for at least 5 years with the final target of making UMKM for catfish cultivation and catfish processed products. So that, there needs to be a sustainability program conducted between the community, the village government, and the academic community.

4 module. The configuration used is 13S5P (65 cells), resulting in a total voltage of 48.1 V and a capacity of 14 Ah, or equivalent to 673.4 Wh of energy. Compared to the ECGO2 built-in battery that requires 4-7 hours of charging time, this system is able to speed up charging to ±1.6 hours using a 7 A current charger. Test results using an oscilloscope show that the voltage of the assembled battery is more stable under load than that of a single battery, with minimal ripple. The estimated operating time of an 800 W electric motor using a 673.4 Wh battery is about 50 minutes. To achieve 2 hours of operation, the 13S10P configuration or energy-saving mode (400-500 W) can be used. The system is also more cost-effective at Rp2,678 per Wh compared to the manufacturer's version of Rp4,464 per Wh, as well as improved safety against leakage and overheating.
