Abstract

Penelitian ini menguji keterkaitan antara free float sebagai variabel X dan volatilitas saham berbasis Average True Range persen (ATR%) sebagai variabel Y pada emiten Bursa Efek Indonesia. Berangkat dari peran free float sebagai proksi pasokan saham yang benar-benar dapat diperdagangkan publik, studi ini memposisikan sebaran kepemilikan publik sebagai elemen mikrostruktur yang berpotensi memoderasi gejolak harga. Data sekunder dikumpulkan dari laporan free float resmi emiten/BAE dan harga harian OHLC, dengan sampel 45 emiten​. Analisis dilakukan melalui statistik deskriptif, korelasi Pearson dan Spearman dengan bootstrap, serta regresi OLS bivariabel. Temuan ini mengindikasikan bahwa peningkatan porsi saham publik cenderung menurunkan volatilitas efektif di pasar sekunder, mendukung rasionalitas kebijakan BEI terkait free float minimum sekaligus memberi sinyal bagi investor bahwa sebaran kepemilikan publik merupakan indikator risiko harga lintas emiten.

Abstract

The effectiveness of public services in Indonesia continues to face challenges due to inconsistent compliance with operational regulations and weaknesses in internal control systems, particularly in transportation service providers. Although previous studies have examined compliance audits and internal control separately, empirical evidence regarding their combined influence on service effectiveness in ferry transportation remains limited. This study aims to examine the effect of compliance audits and internal control on service effectiveness at PT ASDP Indonesia Ferry (Persero) Bengkulu Branch. A quantitative approach with a causal associative design was employed. The study involved all 30 employees of the company using a saturated sampling technique. Primary data were collected through structured questionnaires and analyzed using multiple linear regression. The findings indicate that compliance audit does not have a significant effect on service effectiveness (p = 0.475), whereas internal control has a positive and significant effect (p < 0.001). Simultaneously, both variables significantly influence service effectiveness (p < 0.001). These findings highlight the strategic role of strengthening internal control systems in improving the quality and effectiveness of ferry transportation services while providing empirical evidence within the context of Indonesia's maritime transportation sector.
