Abstract

Business efficiency proves the ability of its managerial in facing intense competition, especially those of sharia insurance companies. The purpose of this study was to examine the relationship between growth assets, gross contributions, claims and investment to the efficiency of sharia insurance company in 2016-2019. This study used DEA analysis (Data Envelopment Analysis) to measure the efficiency level of seven sharia insurance companies in 2016 to 2019 by using input variables (asset totals, claim payments) and output variable (revenues and tabarru’ funds), then examine the relationship of independent variables (growth assets, gross contributions, claims and investment) against dependent variable (the efficiency of sharia insurance company) by using multiple linear regression analysis. The results of the study demonstrated that the seven companies experienced the efficiency level of 100% in 2016 to 2017, but in 2018 to 2019 the three sharia insurance companies (PT Asuransi Jiwa Syariah Al-Amin, PT Asuransi Jiwa Syariah Jasa Mitra Abadi and PT Reasuransi Syariah Indonesia; or PT ReINDO Syariah) experienced an inefficiency. Then the relationship of growth assets, gross contributions, claims and investment to the efficiency of sharia insurance company does partially not effect significantly, but does simultaneously effect significantly.

Abstract

Amid intensifying competition among educational institutions and the rapid expansion of digital platforms, schools must adopt effective digital marketing strategies to attract prospective students. This research examines students’ perceptions of the implementation of digital marketing at the Global Islamic Boarding School (GIBS) in Barito Kuala Regency, South Kalimantan, Indonesia. Data were collected from 95 students using a structured questionnaire comprising 20 variables related to digital marketing and word-of-mouth communication. A hybrid analytical framework integrating K-Means Clustering and Decision Tree analysis was employed to identify perception-based segments and determine key differentiating indicators. The Elbow method indicated an optimal three-cluster solution, resulting in highly positive, negative, and moderate perception groups. Decision Tree results revealed that engaging content (B7), social media stability (B12), and invitation to attend school (C19) were the most influential variables distinguishing clusters, with satisfactory classification performance supporting the robustness of the segmentation. The findings suggest that emotionally engaging and experientially rich content plays a more decisive role in shaping student perceptions than purely technical aspects of digital media management. Accordingly, schools should optimize their digital marketing strategies by emphasizing authentic student experiences, maintaining consistent, stable online communication, and incorporating persuasive calls to action to enhance prospective students’ interest.
