Abstract

Family communication plays a decisive role in shaping moral integrity, emotional stability, and ethical continuity within human relationships. This study examines how Sayyidina Ali ibn Abi Talib conceptualizes ethical communication and how his teachings can strengthen family communication within a normative religious framework. Employing a qualitative normative–religious research design, the study conducts an interpretative library-based analysis of Nahj al-Balaghah as the primary source, supported by classical and contemporary Islamic ethical scholarship. The findings identify five interrelated ethical principles governing family communication: wisdom (hikmah), truthfulness (sidq), gentleness (rifq), self-restraint (hilm), and moral accountability in speech. These principles demonstrate that communication is not a neutral social skill but a morally accountable practice that reflects character and spiritual consciousness. The study contributes a coherent normative ethical framework that integrates classical Islamic moral philosophy into contemporary discourse on family communication. It implies that strengthening family relationships requires ethical reflection, emotional discipline, and moral responsibility in everyday speech.

Abstract

This study aims to examine how Islamic education contributes to the construction of family resilience through socio-theological mechanisms in West Nusa Tenggara (NTB), Indonesia. In the context of rapid modernisation, socio-economic vulnerability, and recurrent natural disasters, families face increasing pressures that threaten stability and adaptive capacity. Previous studies on family resilience have emphasised psychological and structural factors but have insufficiently examined the role of religion and education in highly religious societies. This research employs a qualitative embedded single-case study design focusing on pesantren, majlis taklim, and resilient family units across Lombok and Sumbawa. Data were collected through in-depth interviews, participant observation, and document analysis and were analysed thematically using Family Resilience Theory and Social Capital Theory within a socio-theological framework. The findings reveal three interrelated processes. First, theological meaning-making rooted in tawakkul, sabr, and syukr enables families to reinterpret crises as purposeful divine tests, strengthening emotional regulation and optimism. Second, religious institutions function as social capital networks that provide trust-based support, collective problem-solving, and material assistance. Third, pedagogical transmission of family ethics and roles embeds moral discipline, adaptive communication, and relational responsibility in daily family life. These findings extend family resilience and social capital theories through an Islamic socio-theological lens and highlight Islamic educational institutions as strategic sites for resilience-building. Policymakers and educators are encouraged to integrate family counselling and psychosocial support into Islamic educational curricula.

Abstract

Jor Hamlet, Jerowaru Village, Jerowaru District, East Lombok Regency, is a center for shrimp paste production with significant development potential. Limited access to capital is the main constraint due to the low awareness and financial literacy among most entrepreneurs. This situation requires intervention through education, carried out with direct assistance in the form of workshops on the introduction and use of digital financial reporting applications. This training aims to enhance financial management skills in a more practical and professional manner, thereby improving business competitiveness and sustainability. The focus of this mentoring activity is the introduction of the application and practical simulation of automatically preparing financial reports using the BukuWarung application. The structured and effective mentoring method is carried out in three main stages: First, initial analysis and preparation, which involves identifying the partner's needs and preparing materials and manuals. Second, workshops, which involve introducing and directly simulating the use of the BukuWarung application. This includes guidance on downloading the app, introduction to its main features and functions, account creation, recording transactions, evaluating financial reports to measure business performance, as well as interactive discussions. Third, monitoring and evaluation, by ensuring that participants can use the application independently and consistently. This mentoring activity has had a positive impact on entrepreneurs, including improved financial literacy and strengthened commitment to regularly record business activities in financial reports. This practice allows them to enhance the efficiency and competitiveness of their businesses.

Abstract

Harga saham tidak selalu mencerminkan nilai fundamental perusahaan dan investor seringkali irasional karena dapat dipengaruhi oleh faktor psikologis, emosi dan bias pribadi dalam mengambil keputusan investasi. Penelitian ini merupakan studi peristiwa untuk menguji fenomena overreaction terhadap kandungan informasi terhadap pengumumuman peluncuran indeks di Bursa Efek Indonesia, yaitu IDXESGL, IDXHIDIV20, dan IDXLQ45LCL. Analisis terhadap fenomena overreaction sebagai informasi penting yang dapat membantu investor agar dapat terhindar dari keputusan investasi yang kurang tepat. Penelitian ini menggunakan pendekatan studi peristiwa, dengan menganalisis abnormal return di periode seputar pengumuman (event window), yaitu 5 sampai dengan 10 hari sebelum maupun sesudah hari pengumuman peluncuran dari setiap indeks. Data yang dikumpulkan meliputi harga saham individual yang terdaftar pada masing-masing indeks, indeks harga pasar, dan suku bunga bebas risiko (BI rate) secara terus menerus selama periode estimasi dan event window. Uji variabel menggunakan uji statistik parametrik yaitu one sample t-test dan paired sample test untuk data yang berdistribusi normal, dan uji non-parametrik untuk data yang berdistribusi tidak normal. Hasil penelitian menunjukkan bahwa reaksi pasar bervariasi dalam merespon pengumuman peluncuran indeks baru di Bursa Efek Indonesia, overreaction terjadi pada pengumuman peluncuran indeks ESG Leaders (ESGL) dan LQ45 Low Carbon Leaders (LQ45LCL), dan tidak terjadi pada indeks HIDIV20. Penelitian ini berkontribusi terhadap literatur keuangan dengan menyajikan bukti empiris mengenai keberadaan fenomena overreaction di pasar modal Indonesia, yang mencerminkan karakteristik pasar dengan tingkat efisiensi bentuk lemah.     Stock prices do not always reflect a company's fundamental value, and investors are often irrational due to the influence of psychological factors, emotions, and personal biases in making investment decisions. This study is an event study aimed at examining the phenomenon of overreaction to the informational content of index launch announcements on the Indonesia Stock Exchange, specifically the IDXESGL, IDXHIDIV20, and IDXLQ45LCL. The analysis of overreaction is considered important information that can help investors avoid making poor investment decisions. This research employs an event study approach by analyzing abnormal returns during the period surrounding the announcements (event window) specifically, 5 to 10 days before and after the event date of each index launch. The data collected include individual stock prices listed in each respective index, the overall market index, and the risk-free interest rate (BI rate), continuously observed during the estimation period and the event window. Statistical testing of variables uses parametric tests such as the one-sample t-test and paired sample t-test for normally distributed data, and non-parametric tests for non-normally distributed data. The results show that market reactions vary in response to the launch announcements of new indices on the Indonesia Stock Exchange, Overreaction was observed in the announcements of the ESG Leaders (IDXESGL) and LQ45 Low Carbon Leaders (IDXLQ45LCL) indices, but not in the HIDIV20 index. This research contributes to the financial literature by providing empirical evidence of overreaction in Indonesia capital market which reflects the characteristics of the weak-form market efficiency.
