Abstract

Salah satu kendala yang dapat membatasi pertumbuhan dan produksi tanaman pada lahan kering adalah ketersediaan air yang rendah,karena itu diperlukan varitas kedelai yang berpotensi produksi dan mempunyai kemampuan adaptasi yang tinggi terhadap cekaman air. Tujuan Penelitian untuk mengetahui pengaruh cekaman air terhadap pertumbuhan dan produksi dari beberapa varitas tanaman kacang kedelai. Hasil penelitian menunjukkan bahwa taraf pemberian air berpengaruh nyata terhadap produksi tanaman yaitu jumlah polong,tapi tidak berpengaruh nyata terhadap tinggi tanaman,jumlah cabang, bobot polong dan berat kering akar tanaman. Perlakuan yang terbaik dari taraf pemberian air adalah perlakuan A1 =80 % (1200 ml air/polybag). Kemudian perlakuan tiga varitas berpengaruh nyata terhadap pertumbuhan dan produksi tanaman kacang kedelai yaitu tinggi tanaman,jumlah polong, bobot polong dan berat kering akar tanaman ,namun tidak berpengaruh nyata terhadap jumlah cabang tanaman. Sedangkan kombinasi taraf pemberian air dari ketiga varitas kacang kedelai berpengaruh tidak nyata terhadap pertumbuhan dan produksi tanaman.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh taraf pemberian air dan pupuk kandang ayam terhadap pertumbuhan tanaman jeruk purut. Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) Faktorial dengan dua faktor yang diteliti yaitu: 1. Faktor perlakuan pertama adalah Taraf Pemberian Air (A) terdiri dari 5 taraf perlakuan, yaitu : A0 = 100%, A1 = 80 %, A2 = 60%, A3 = 40 %. A4 = 20%. 2. Faktor perlakuan kedua adalah pupuk Kandang Ayam (K) yang terdiri dari 3 taraf perlakuan, yaitu : K0 = 0 kontrol, K1 = 50g/polybag, K2 = 100 g/polybag. Parameter yang diamati adalah tinggi tanaman (cm), jumlah cabang (cabang), diameter batang (mm), jumlah daun tanaman (helai). Hasil penelitian menunjukkan bahwa taraf pemberian air berpengaruh nyata terhadap pertumbuhan tanaman jeruk purut yaitu tinggi tanaman, jumlah cabang, diameter batang dan jumlah daun. Kemudian pemberian pupuk kandang ayam berpengaruh nyata terhadap pertumbuhan tanaman jeruk purut yaitu diameter batang dan jumlah daun tanaman. Sedangkan kombinasi aplikasi taraf pemberian air dan pupuk kandang ayam berpengaruh nyata terhadap semua parameter yang diamati.

Abstract

Proverbs that represent their values and perspective are part of the rich cultural legacy of the Batak people of North Sumatra, Indonesia. "Dalihan Natolu" (translates as "The Three Hearth Stones") is one such proverb. This proverb is an important part of Batak social structure and values, which makes it a valuable topic for linguistic study. The "Dalihan Natolu" proverb is examined in this study using the Systemic Functional Grammar (SFG) theoretical paradigm. SFG is a linguistic approach that examines the ways in which language is employed to create meaning and depict the outside world. We can learn more about the grammatical and semantic elements of the "Dalihan Natolu" proverb that contribute to its cultural importance by using SFG to analyze it. The ideational, interpersonal, and textual meta functions of SFG are the three main areas of analysis. The proverb's representation of experiences and construction of reality are examined by the ideational meta function. The interpersonal meta function looks at how the proverb conveys the speaker's position and enacts social interactions. The textual meta function looks at the proverb's method of arranging ideas to create a logical and cohesive message. The study's goal is to identify the language structures and patterns that underlie the cultural significance and symbolic force of the "Dalihan Natolu" adage through this in-depth investigation. Understanding the proverb from the standpoint of Systemic Functional Grammar helps us to better grasp the richness and complexity of Batak cultural expression as well as its applicability in the contemporary era. The results of this work advance the field of linguistic analysis of cultural artefacts and the academic understanding of Batak language and culture. In light of the swift advancements in social and technological spheres, the knowledge acquired can also contribute to the preservation and promotion of Batak cultural heritage.

Abstract

Visionary leadership has a strategic role in the development of library services, especially in facing the challenges of digital transformation and the increasing need for user information literacy. This study aims to analyze a visionary leadership model in the development of digital literacy-based library user education programs at the Efarina University Library. This study uses a qualitative approach with a case study method. Data collection techniques include observation, in-depth interviews with library leaders and librarians, as well as analysis of library program and policy documents. The results of the study show that the application of visionary leadership contributes significantly to the planning, implementation, and evaluation of digital literacy-based user education programs. Library leaders play the role of agents of change through the formulation of adaptive visions, strengthening the competence of librarians, utilizing information technology, and collaborating with the academic community. The user education program developed not only improves users' ability to access and evaluate digital information sources, but also encourages optimal use of library services. This study concludes that the visionary leadership model is a key factor in the successful development of digital literacy-based user education programs in the university library environment.

Abstract

This study investigates the phenomenon of sexist verbal violence on social media through a psycholinguistic lens, focusing on the linguistic forms, communicative functions, and psychological impacts of abusive language directed at women. Triggered by the growing prevalence of gendered hate speech on platforms such as TikTok and Instagram, particularly targeting female public figures, this research employs a descriptive qualitative method supported by speech act theory (Austin, 1962; Searle, 1969). A total of 150 comments were analyzed, of which 55 were identified as containing sexist verbal abuse. The findings reveal that these utterances typically involve illocutionary speech acts such as insults, verbal sexual harassment, gender stereotyping, and moral policing. The corresponding perlocutionary effects include emotional harm, such as shame, fear, and diminished self-confidence in the victims. From a psycholinguistic perspective, the production of such language reflects internalized gender bias, affective disinhibition, and the activation of negative cognitive schemas. The study further highlights how digital anonymity and ethical disinhibition enable users to express aggression with minimal accountability. Overall, the results indicate that language is strategically used to exert power and reinforce patriarchal norms within digital discourse. This research underscores the need for greater linguistic awareness, the promotion of digital empathy, and the implementation of more responsive communication ethics in online environments. Creating safer, more inclusive digital spaces requires a multidimensional approach involving education, platform regulation, and cultural change in how language is used and interpreted.

Abstract

This study examines the effectiveness of WordWall, a digital game-based learning platform, in improving students’ English vocabulary achievement. Conducted at SMP Negeri 4 Kota Pematangsiantar during the 2025/2026 academic year, the research involved 62 seventh-grade students divided into two groups: an experimental group taught using WordWall and a control group taught through traditional textbook-based instruction. Employing a quasi-experimental design with pre-test and post-test procedures for both groups, the study found a notable increase in the vocabulary scores of the experimental group compared to the control group. The experimental group’s mean post-test score (85.06) surpassed the school’s minimum mastery criterion (KKM) of 72, while the control group’s mean score was 71.6. Results from paired and independent sample t-tests indicated a significant difference (p < 0.05) between the two groups, validating the positive influence of WordWall on vocabulary acquisition. Moreover, students exposed to WordWall showed improved understanding and retention of word formation, such as recognizing different word classes (nouns, verbs, etc.). These findings highlight that incorporating digital game-based tools like WordWall can enhance both student engagement and learning outcomes. The study concludes that WordWall effectively supports vocabulary development while promoting a more interactive and learner-centered classroom environment, and recommends its adoption by teachers to overcome vocabulary learning challenges in English education.
