Abstract

A research has been carried out with the aims to: 1. study the influence of both the kind and concentration of cytokinins on palea and lemma growth in in vitro culture; 2. study the influence of palea and lemma age towards external application of cytokinin in in vitro culture; and3. determine the best palea-lemma age, kind and concentration of cytokinin which resulted the best growth of palea and lemma in in vitro culture. The used experimental method was Completely Randomised Design (CRD) with factorial treatment pattern. The applied treatment consisted of three factors i.e. palea-lemma age (U): (55, 60, and 65 days after planting); kind of cytokinin (S): (BAP and Kinetin); and Cytokinin Concentration (K): (0, 5, 10, and 15 M) with 3 replications. The observed variables were the palea and lemma growth with the parameters were palea-lemma length and width. The results showed that the kind of cytokinin had influenced the growth of palea-lemma in in vitro culture, and kinetin has better influence on the palea-lemma growth. The age of the palea-lemma determined the responsiveness of the palea-lemma towards external application of cytokinin. Older palea-lemma showed less responsive than younger ones towards external application of plant growth regulators. Moreover, the treatment combination (U1S2K2) (10 µM Kinetin applied to 55-day-old rice palea-lemma) had the best effect on increasing the size of palea-lemma of IR 64 rice.

Abstract

Soybean (Glycine max (L.) Merril) is one of the most important grain-producing crops after rice, wheat, millet and barley. Pollen is a male gametophyte produced by seed plants. Pollen can be used for plant identification because it has a distinctive structure and ornamentation, besides that it can also be used as a plant breeding agent as a contributor to male parental characters. The character of pollen as parental male is very important in plant breeding. One way to know the quality of pollen is to look at its viability. Pollen viability can be tested by staining method or by germination method. Pollen viability is known to be lost over a certain period of time. The purpose of this study was to determine the effect of storage time on viability of soybean pollen, and to determine the best storage period with the highest viability of soybean pollen. This research was conducted experimentally with a Completely Randomized Design (CRD) consisting of 4 treatments, namely P0, Control. P1, 7 days of storage. P2, 14 days of storage. P3, 21 days of storage. The independent variable is variation in storage time while the dependent variable is pollen viability. The parameters observed were the number of stained pollen, germination capacity, and the length of the germinating pollen tube as evidence that the pollen was viable. The research data obtained were analyzed using Analysis of Variance (ANOVA) with an error rate of 5%, then continued with the BNT test with an error rate of 5%. The results showed that the provision of storage time treatment on soybean pollen had an effect on pollen viability, namely by reducing pollen viability. The best shelf life to get the highest pollen viability in soybean pollen is 0 to 7 days after the sample is taken.

Abstract

This study examines the relationship between cultural heritage and syntactic evolution in multilingual societies, focusing on cross-generational language transmission. Employing a mixed-methods approach, it analyzes linguistic practices, cultural narratives, and syntactic patterns across three generational cohorts in five distinct multilingual communities. Findings reveal significant generational shifts, with elders preserving traditional syntax linked to cultural rituals, while younger cohorts exhibit syntactic simplifications and hybrid constructions influenced by dominant languages. Statistical analyses underscore the role of cultural practices in shaping linguistic patterns, highlighting the dynamic interplay between heritage preservation and linguistic innovation in contexts of societal bilingualism and intercultural interaction. The research demonstrates that syntactic changes correlate strongly with the frequency and depth of cultural engagement, with participants who actively participate in traditional practices showing greater retention of heritage language syntactic features. Furthermore, we identify specific linguistic mechanisms through which cultural transmission influences syntactic maintenance and innovation, including ritualized speech patterns, narrative structures, and metaphorical expressions embedded in cultural practices. This study contributes to theoretical understandings of language change by proposing a cultural-syntactic framework that helps explain the variable trajectories of heritage languages in diverse multilingual contexts.

Abstract

The purpose of this study is to discover the role of Sociolinguistic and Sociopragmatic for primary school students in the developmental process of language learning by children. School-aged children find themselves in a developmental phase where they organize and integrate a variety of developmental skills to adapt to increasingly complex tasks, including language development. Language development is essentially a person's ability to communicate with their surroundings. Communication is used to build relationships with others in order for us to feel part of the environment. Language skills develop throughout the school year. Students are increasingly able to better understand and interpret spoken, written and body language communications, enabling them to understand the context and understand the people around them. Language development is related to cognitive development, meaning that intelligence factors and understanding of the environment around children greatly influence the development of their language skills. As children grow and develop, their language skills begin to develop from very basic to complex levels. Language development is influenced by the environment because language is essentially the result of learning from its environment. Children learn languages ​​and other things by imitating and repeating words used by adults. their language skills start to develop from a very basic level to a complex level.

Abstract

This contrastive linguistic study examines the phonological systems of Indonesian and English to identify areas of difficulty for Indonesian learners of English pronunciation. Through a systematic comparison of vowel and consonant inventories, phonotactic constraints, stress patterns, and prosodic features, this research identifies key points of interference that contribute to pronunciation challenges. The study employs acoustic analysis of speech samples from 120 Indonesian learners of English across different proficiency levels, combined with perceptual assessments by native English speakers. Findings reveal significant differences in vowel systems, consonant clusters, word stress placement, and intonation patterns that directly correlate with pronunciation difficulties. The research proposes a pedagogical framework that integrates principles of contrastive analysis with contemporary pronunciation teaching methodologies, including explicit phonological instruction, acoustic modelling, and technology-enhanced practice. The implications suggest that pronunciation instruction can be significantly improved through targeted interventions that address language-specific interference patterns while building on positive transfer opportunities.
