Sistem Water Level Control (WLC) Sebagai Pengontrolan Pompa Reservoar
Get PDFSembilan puluh persen kebutuhan air PPPG Teknologi Medan disuplay dari air bawah tanah yang dihisap dengan menggunakan pompa aksial dan selanjutnya ditampung pada bak penampung air (reservoar) bawah. Agar air dapat didistribusikan secara merata, air dari bak penampung bawah dipompa dengan pompa sentrifugal ke bak penampung (reservoar) atas yang berfungsi sebagai bak distribusi. Sebagai penggerak mula untuk memutar pompa digunakan motor induksi tiga phasa rotor sangkar. Pemilihan motor induksi tiga phasa sebagai penggerak mula, adalah karena motor jenis ini mempunyai torsi yang besar dan mudah untuk dikendalikan. Agar proses pengisian air pada bak penampung dapat berjalan secara efektif dan efisien, maka sistem pengendalian pompa melalui pengontrolan motor penggerak dirancang secara otomatis, sehingga pompa dapat diatur, pada saat kapan harus mengisi dan pada saat kapan harus berhenti mengisi. Komponen-komponen kontrol yang digunakan untuk mengendalikan bekerja tidaknya motor pompa secara otomatis adalah kontraktor magnit, Thermal Over Load Relay dan Water Level Control Type Solid State
Peningkatan Keterampilan Membaca melalui Model Pembelajaran Deep Learning di Sekolah Dasar Negeri 101103 Tolang Jae
Get PDFThis study aims to improve the reading skills of fourth-grade students at Public Elementary School 101103 Tolang Jae through the application of the deep learning instructional model. In this context, deep learning is not related to artificial intelligence algorithms but is employed as a pedagogical approach that emphasizes deep comprehension, reflection, and the application of concepts in real-life situations. The research employed a Classroom Action Research (CAR) design adapted from Kemmis and McTaggart’s model, which consists of four stages: planning, implementation, observation, and reflection. The study involved 28 students with varying literacy levels. Data were collected through reading literacy tests administered at each learning cycle and analyzed using quantitative descriptive methods. The results revealed a significant improvement in students’ literacy performance from cycle I to cycle II, indicated by an increase in the proportion of students scoring above 80, from 17.8% to 35.7%. The use of critical discussions, concept mapping, and meaning exploration effectively enhanced students’ understanding of reading materials and fostered critical thinking toward texts. Therefore, the deep learning-based instructional approach proved effective in improving reading literacy skills among elementary students, particularly in rural schools with limited learning resources
REPRESENTATION OF NATIONALISM VALUES IN FAOZAN RIZAL’S HABIBIE & AINUN MOVIE SCRIPT

INTERSECTING FORMS OF VIOLENCE AND TRAUMA IN KATHLEEN GLASGOW’S GIRL IN PIECES: A LITERARY-SOCIOLOGICAL ANALYSIS OF FEMALE MENTAL HEALTH
Get PDFThis article analyzes the complex representation of violence and trauma in Kathleen Glasgow’s Girl in Pieces, focusing on the protagonist Charlie Davis. Through Johan Galtung’s violence typology—direct, structural, and symbolic—the study reveals how Glasgow constructs an emotionally resonant narrative of trauma that is deeply rooted in systemic and interpersonal failures. Charlie’s self-harm, institutional neglect, and internalized shame illustrate how violence is experienced not only through physical abuse but also through social and cultural mechanisms. The research applies a sociological approach to literature and trauma theory, situating the novel within the broader context of Young Adult (YA) fiction that foregrounds psychological suffering. This approach reveals that Girl in Pieces is not merely a coming-of-age story but a social critique of how institutions respond to marginalized female trauma. Using qualitative content analysis, the article contributes to discussions in trauma-informed literary pedagogy and young adult mental health literature. Findings suggest that literature, when interpreted through a sociological and trauma-sensitive lens, holds critical potential for reshaping understandings of mental illness, recovery, and gendered pain. The study supports the integration of trauma narratives into educational spaces as a means to foster empathy, awareness, and policy reform around youth mental health
FORGIVENESS AS A PATHWAY TO TRAUMA HEALING: A NARRATIVE EXAMINATION OF COLLEEN HOOVER’S REMINDERS OF HIM
Get PDFThis study examines the role of forgiveness in the trauma healing process as portrayed in Colleen Hoover’s Reminders of Him. Focusing on the main character, Kenna Rowan, it explores how she experiences emotional trauma and how forgiveness facilitates her recovery. Using a qualitative descriptive method with a psychological approach, the analysis applies Worthington’s model of decisional and emotional forgiveness and Enright’s Four-Phase Model of Forgiveness to identify the stages of healing depicted in the narrative. The findings reveal that Kenna exhibits symptoms of psychological trauma, including anxiety, guilt, avoidance, flashbacks, and difficulty maintaining relationships. The study identifies two types of forgiveness—decisional, a conscious choice to forgive, and emotional, a deeper emotional release—and demonstrates how Kenna’s journey reflects the four phases of forgiveness: uncovering, decision, work, and deepening. Through self-reflection, acceptance, and social support, she achieves self-forgiveness and re-establishes connections with her daughter and others. The research concludes that forgiveness is a key factor in emotional recovery and that literature can serve as a valuable medium for understanding psychological healing and personal growth
MANIFESTATIONS OF PATIENCE IN WINSTON GROOM’S FORREST GUMP: A LITERARY PSYCHOLOGICAL STUDY BASED ON SZUTTA’S MODEL
Get PDFThis study examines the manifestation of patience as a moral virtue in Winston Groom's novel Forrest Gump through Szutta's (2020) theoretical framework of patience competence. Using qualitative methodology with descriptive analysis, this research investigates how the protagonist exemplifies patience through two core characteristics: perseverance and sincerity. The findings reveal that Forrest's perseverance manifests as sustained determination in overcoming life challenges, particularly evidenced in his shrimp business venture where he persists despite initial failures. Simultaneously, his sincerity appears through selfless actions and unconditional assistance without expectation of reward. The analysis demonstrates that patience in Forrest Gump represents not passive endurance but active competence - a strategic virtue enabling him to navigate bullying, personal loss, and social prejudice while maintaining moral integrity. The integration of perseverance and sincerity transforms his perceived intellectual limitations into extraordinary resilience, positioning patience as a transformative force in human experience. This study contributes to literary psychology by illustrating how virtue theory can illuminate character development while affirming literature's capacity to reflect complex psychological realities

PEMANFAATAN KULIT MANGGIS (GARCINIA MANGOSTANA) SEBAGAI BAHAN BAKU NANOPARTIKEL LIPID PADAT (SLN) UNTUK PRODUK KESEHATAN DALAM PEMBERDAYAAN MASYARAKAT DI DESA BATU MBELIN, KECAMATAN SIBOLANGIT
Get PDFKulit manggis (Garcinia mangostana) diketahui memiliki kandungan senyawa bioaktif, terutama xanton, yang berpotensi sebagai antioksidan, antiinflamasi, dan antikanker. Namun, pemanfaatan kulit manggis sebagai bahan baku kesehatan masih terbatas karena rendahnya kelarutan dan bioavailabilitas senyawa aktif tersebut. Salah satu pendekatan inovatif yang dapat dilakukan adalah melalui formulasi Solid Lipid Nanoparticles (SLN), yang mampu meningkatkan stabilitas, kelarutan, serta efektivitas penghantaran senyawa bioaktif dalam tubuh. Penelitian dan pengabdian ini bertujuan untuk memanfaatkan kulit manggis sebagai bahan baku SLN, sekaligus memberikan pelatihan kepada masyarakat Desa Batu Mbelin, Kecamatan Sibolangit, dalam mengembangkan produk kesehatan berbasis teknologi nano. Metode kegiatan meliputi ekstraksi kulit manggis, formulasi SLN, uji karakterisasi sederhana, serta pendampingan masyarakat dalam pengolahan produk kesehatan. Hasil yang diharapkan adalah terciptanya produk kesehatan berbasis SLN dari kulit manggis yang bernilai ekonomis, peningkatan pengetahuan masyarakat terkait teknologi nano dalam bidang kesehatan, serta terciptanya peluang usaha lokal yang berkelanjutan. Dengan demikian, kegiatan ini tidak hanya berkontribusi pada pengembangan ilmu pengetahuan dan teknologi, tetapi juga memberdayakan masyarakat dalam meningkatkan kesejahteraan melalui pemanfaatan sumber daya alam lokal
