Learning from Loss: The Story of a Student Rebuilding His Motivation to Study After His Father Passed Away
No full textThe death of a father during a student’s university years is a deeply disruptive emotional experience that can undermine personal stability and significantly affect learning motivation. At this developmental stage, students are expected to manage independence and academic responsibilities, making the loss of a paternal figure likely to trigger reduced enthusiasm, concentration difficulties, and shifts in how they interpret the learning process. This study aims to explore the dynamics of learning motivation among students who experienced paternal loss by employing a qualitative phenomenological approach. Three undergraduate students aged 19–23 who lost their fathers during their studies participated in the research. Data were collected through in-depth interviews and observations and analyzed using thematic coding. The findings indicate meaningful changes across four motivational aspects: drive, commitment, initiative, and optimism. Initially, all participants experienced a decline in motivation characterized by sadness, decreased focus, and weakened academic goals. Over time, however, their motivation gradually rebuilt through personal reflection, family support, social responsibility, and the development of new meaning in their educational pursuits. These results imply the need for higher education institutions to provide more responsive psychological and academic support to bereaved students in order to facilitate adaptive recovery and sustain their academic engagement
The Contribution of Parental Support as a Determinant of Learning Motivation in Students with Dyslexia
No full textIn Indonesia, approximately 10% of students have dyslexia, but it often goes undetected. Children aged 6–7 years old generally have mastered reading skills, but individuals with dyslexia face different obstacles. Suboptimal stimulation in reading, writing, and arithmetic during childhood can hinder the development of critical thinking in adolescence. This study aims to examine parents' experiences in providing support that plays a role in increasing the learning motivation of students with dyslexia. The method used is qualitative with a case study approach. Data were collected through semi-structured interviews guided by Smet's theory of emotional, appreciative, instrumental, and informational support. The research subjects were two parents who have children with dyslexia at Private Elementary School X in Sidoarjo Regency. Data analysis was conducted using Strauss and Corbin's techniques, including open coding, axial coding, and selective coding, with validity testing through source triangulation. Parental support was proven to foster learning motivation in dyslexic students. Emotional support builds children's self-acceptance and self-confidence, while reward and instrumental support help create positive learning experiences and academic readiness. Informative support enriched the children's learning strategies and understanding of their condition. These efforts contributed to the development of intrinsic motivation and psychological well-being in dyslexic children. These findings emphasize the importance of holistic parental involvement in creating a conducive learning environment for the development of dyslexic children

From Fear to Hope: Psychological Well-being Victims of Domestic Violence
No full textDomestic Violence (DV) is a complex phenomenon that not only inflicts physical harm but also leaves deep psychological scars on victims. Data from the Indonesian National Commission on Violence Against Women (Komnas Perempuan) in 2023 indicates a significant increase in DV cases, particularly against women, often affecting their quality of life and psychological well-being. This study aims to explore the subjective experiences of DV survivors regarding their psychological well-being. Using a qualitative phenomenological approach, the study involved three adult women who had experienced DV, with data collected through in-depth interviews and observations. Data analysis employed an interpretative phenomenological method to uncover the deeper meanings of the victims’ lived experiences. The findings reveal that DV negatively impacts the six dimensions of psychological well-being identified by Ryff: self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth. The implications of this study highlight the necessity of a holistic intervention that not only focuses on victims’ psychological recovery but also strengthens social support systems, provides adequate protection, and empowers survivors to rebuild their identity, independence, and overall quality of life.Kekerasan Dalam Rumah Tangga (KDRT) merupakan fenomena kompleks yang tidak hanya menimbulkan luka fisik, tetapi juga meninggalkan dampak psikologis mendalam bagi korban. Data Komnas Perempuan tahun 2023 menunjukkan peningkatan signifikan kasus KDRT, khususnya terhadap perempuan, yang sering kali memengaruhi kualitas hidup dan kesejahteraan psikologis mereka. Penelitian ini bertujuan mengeksplorasi pengalaman subjektif korban KDRT terkait kondisi kesejahteraan psikologis mereka. Menggunakan pendekatan kualitatif fenomenologis, penelitian melibatkan tiga perempuan dewasa yang pernah mengalami KDRT, dengan metode pengumpulan data melalui wawancara mendalam dan observasi. Analisis data dilakukan menggunakan metode fenomenologi interpretatif untuk mengungkap makna mendalam dari pengalaman korban. Hasil penelitian menunjukkan bahwa KDRT berdampak negatif pada enam dimensi kesejahteraan psikologis menurut Ryff, meliputi penerimaan diri, hubungan positif dengan orang lain, otonomi, penguasaan lingkungan, tujuan hidup, dan pertumbuhan pribadi. Implikasi dari temuan ini menunjukkan perlunya intervensi holistik yang tidak hanya berfokus pada pemulihan psikologis korban, tetapi juga pada penguatan sistem dukungan sosial, penyediaan perlindungan yang memadai, serta pemberdayaan korban agar mampu membangun kembali identitas, kemandirian, dan kualitas hidup mereka
Interpretasi Struktur Geologi Berdasarkan Fault Fracture Density (FFD) dan Implikasinya Terhadap Potensi Likuifaksi di Daerah Lempake, Kecamatan Sungai Pinang, Kota Samarinda Provinsi Kalimantan Timur
Full text linkPemahaman terhadap struktur geologi suatu daerah sangat penting dalam konteks mitigasi bencana alam, terutama untuk menilai potensi terjadinya likuefaksi. Salah satu metode yang dapat digunakan untuk memahami struktur geologi adalah analisis Fault Fracture Density (FFD), yang mengukur dan memetakan kepadatan rekahan dan sesar di wilayah tertentu. Penelitian ini diterapkan di daerah Lempake, Kecamatan Sungai Pinang, Kota Samarinda, untuk mengidentifikasi potensi likuefaksi yang dapat dipicu oleh aktivitas seismik. FFD digunakan untuk menginterpretasi struktur geologi dan menilai risiko likuefaksi, dengan fokus pada zona-zona yang memiliki kepadatan rekahan tinggi, yang berpotensi meningkatkan permeabilitas tanah dan memungkinkan akumulasi air. Penelitian ini menggabungkan pendekatan mixed-method, mengintegrasikan analisis kuantitatif dan kualitatif melalui data Digital Elevation Model (DEMNAS), pemetaan FFD, pengukuran anomali gaya berat, dan analisis Normalized Difference Water Index (NDWI). Hasil analisis menunjukkan bahwa daerah dengan kepadatan kelurusan tinggi berpotensi mengalami likuefaksi dan kelongsoran, terutama di wilayah dengan kemiringan lereng yang lebih curam dan struktur geologi yang terdeformasi. Temuan ini memberikan wawasan penting bagi pengelolaan risiko bencana geologis di daerah Lempake, dengan rekomendasi praktis untuk perencanaan mitigasi bencana.
