Abstract

This study aims to analyze the structure of economic growth in Probolinggo Regency by identifying basic and non-basic sectors, and to evaluate the role of leading sectors in driving sustainable regional development. Using a descriptive qualitative approach, data were collected through in-depth interviews with informants from the Regional Development Planning Agency (Bappeda) and economic actors, field observations, and analysis of GRDP documents. The results indicate that the agricultural sector remains the backbone (basic sector) of the regional economy, providing a multiplier effect for other sectors. Furthermore, Small and Medium Industries (SMEs) based on natural product processing are beginning to demonstrate a significant role in creating added value. These findings validate the Economic Base Theory, which states that strengthening basic sectors is crucial for stimulating growth in non-basic sectors (trade and services). The study concludes that synergy between government policies and local potential (particularly MSMEs) is key to inclusive development. A recommendation for future research is the use of mixed methods to more precisely quantify sector competitiveness.

Abstract

Hearing impairment in Indonesian adolescents poses significant developmental challenges, including socio-emotional difficulties and risks of cognitive delay, which are exacerbated by limited early interventions and cultural stigma. This qualitative single-case study examines the lived experiences of Suci Cahaya, a 17-year-old female high school student with hearing impairment, with a specific focus on family parenting dynamics, socio-emotional challenges, and religious coping strategies within an Islamic context. Data were collected through in-depth semi-structured interviews, and credibility was strengthened through triangulation of information across sources and perspectives. The findings show a marked shift from Suci’s outgoing childhood to adolescent introversion, precipitated by bullying and communication barriers, yet concurrently buffered by collaborative parenting—her mother’s patient, repetitive guidance and her father’s active advocacy—alongside supportive community engagement. Religious values, including sincerity, sabar (patience), and viewing disability as amanah (divine trust), fortified family resilience, reframed caregiving as spiritual worship, and helped reduce psychological distress. The study concludes that culturally embedded, faith-informed parenting and community support can foster adaptive coping and resilience among adolescents with hearing impairment in Indonesian Muslim families, offering critical insights for the design of inclusive education, family-centered interventions, and faith-integrated policies.
