This study aims to analyze the effect of personalized marketing on customer satisfaction and customer retention, as well as to explain the role of customer satisfaction as a mechanism linking marketing personalization to customers’ decision to remain with a brand. The background of this study is based on the increasing use of data-driven marketing strategies, product recommendations, personalized promotions, and digital communication tailored to customer preferences. In an increasingly competitive business environment, companies are required not only to attract new customers but also to retain existing customers through relevant, convenient, and valuable experiences. This study employed a quantitative explanatory approach, with the population consisting of customers who had received personalized marketing from a particular company or brand. The sampling technique used was purposive sampling, with the criteria that respondents had received personalized promotions and had made repeat purchases. The total sample consisted of 110 respondents. Data were collected using a structured questionnaire with a five-point Likert scale and analyzed using Partial Least Squares Structural Equation Modeling. The findings show that personalized marketing has a positive and significant effect on customer satisfaction. This indicates that promotions, recommendations, and marketing messages that are relevant to customer needs can create more positive customer experiences. Customer satisfaction is also found to have a positive and significant effect on customer retention, meaning that satisfied customers are more likely to make repeat purchases, continue using products or services, and avoid switching to competitors. In addition, personalized marketing has a direct effect on customer retention, although its effect becomes stronger when mediated by customer satisfaction. The implications of this study emphasize that companies need to develop personalization strategies that are not only data-driven but also relevant, ethical, non-intrusive, and oriented toward customer value. Therefore, personalized marketing can serve as an important strategy for improving customer satisfaction and maintaining long-term customer retention.

The Family Hope Program (Program Keluarga Harapan/PKH) is Indonesia's primary conditional cash transfer (CCT) scheme for poverty alleviation. This study examines PKH effectiveness in improving household welfare among beneficiaries in Oebobo District, Kupang City, East Nusa Tenggara (NTT), employing a Three-Stage Least Squares (3SLS) simultaneous equation approach. The analysis integrates a Gender Equality, Disability, and Social Inclusion (GEDSI) perspective to evaluate Access, Participation, Control, and Benefit (APCB) dimensions for vulnerable groups. A mixed-methods explanatory sequential design was applied to 151 beneficiary households selected via proportional sampling across three urban sub-districts. The 3SLS estimations establish that targeting accuracy (X1) and economic empowerment (X3) are the most significant determinants of PKH effectiveness; PKH effectiveness (Y1) strongly shapes household governance (Y2) through the Family Capacity Building Meetings (P2K2) mechanism; and PKH effectiveness is the dominant determinant of household welfare (Y3), with a near-unity coefficient (β=0.97). GEDSI analysis reveals that female-headed households, the elderly, and persons with disabilities face compounding vulnerabilities inadequately addressed by current program design. The study recommends strengthening data verification systems, embedding economic empowerment as a core pillar, and adopting differentiated targeting based on intersectional vulnerability profiles.

Down syndrome, or Trisomy 21, is the most common chromosomal disorder in humans and is primarily caused by nondisjunction events during meiosis. Although advanced maternal age has long been recognized as the major risk factor, recent scientific evidence indicates that genetic mutations, gene polymorphisms, and meiotic recombination abnormalities also play important roles in the occurrence of Trisomy 21. This literature review aims to analyze the role of genetic mutations in the pathogenesis of Trisomy 21, with emphasis on the mechanisms of nondisjunction, oocyte aging, meiotic recombination errors, and folate metabolism disorders. The method used was a narrative literature review based on seven major scientific sources discussing the genetic and molecular factors underlying Trisomy 21. The findings indicate that genetic mutations and variations affecting meiotic regulation, recombination positioning, chromosome cohesion, and DNA methylation significantly increase the risk of chromosome 21 nondisjunction. In addition, age-related decline in oocyte quality and polymorphisms in folate metabolism genes further exacerbate chromosomal instability. Understanding these mechanisms is essential for the development of genetic counseling, early detection, and more effective prevention and management strategies in the future.  

Flooding is one of the most frequent disasters in DKI Jakarta and contributes not only to physical and economic losses but also to the emergence of various psychological problems among affected communities.

This article reviews the history and transformation of madrasah management in Indonesia. Emerging in the early twentieth century, madrasahs developed as educational institutions that combined the traditional values of Islamic boarding schools (pesantren) with the organizational structure of modern schools. This study employs a literature review method to examine the evolution of madrasah governance from the colonial era to the reform era. The findings reveal three major stages in the development of madrasah management. The first stage was the early period, during which madrasahs were independently managed by religious leaders and Islamic organizations with limited government involvement. The second stage was the post-independence integration period, characterized by increasing government intervention in curriculum development, institutional regulation, and legal recognition. The third stage was the modernization era, marked by the issuance of the Joint Decree of the Three Ministers in 1975 and the enactment of the National Education System Law of 2003, which strengthened the position of madrasahs within the national education system and placed them on an equal footing with public schools. These developments encouraged madrasahs to adopt Madrasah-Based Management (MBM) as a strategy to improve educational quality, effectiveness, and competitiveness. Overall, the transformation of madrasah management reflects an adaptive process that enables madrasahs to respond to educational reforms and societal changes while maintaining their distinctive Islamic identity and educational mission.
