Abstract

Microclimate conditions significantly influence broiler production efficiency in tropical climates. This study evaluated microclimate conditions and their impact on production and economic efficiency in open, semi-closed, and closed housing systems. The research was conducted on three commercial farms representing each housing system in West Java. Microclimate parameters (temperature, relative humidity, heat stress index) and production performance (body weight, FCR, mortality, production index) were measured over one production cycle. Results showed that the closed-house system maintained significantly better microclimate conditions with lower temperature deviations (brooding: -0.52°C; post-brooding: -0.35°C) compared to open (1.06°C; 5.11°C) and semi-closed houses (0.07°C; 1.54°C). The closed-house system achieved significantly higher final body weight (2397.6 g/bird), production index (434), and income over feed cost (Rp 31,238/bird) compared to other systems. Correlation analysis revealed strong negative relationships between temperature parameters and production performance (p<0.01). The closed-house system demonstrated superior microclimate control, leading to significantly improved production efficiency and economic returns.

Abstract

This study aims to analyze the effect of operational costs on operational income (BOPO), financial to deposit ratio (FDR), capital adequacy ratio (CAR), productive asset quality (KAP), minimum statutory reserve (GWM), audit committee (KA), and sharia supervisory board (DPS) on the return on assets (ROA) of Islamic commercial banks. Using quantitative analysis, this study involves 48 samples from 8 Islamic commercial banks over the 2017-2022 period, selected using the purposive sampling method. Based on agency theory and fundamental analysis, the study finds that FDR has a positive effect on ROA, while BOPO and KAP have a negative effect. However, this study fails to prove the effect of CAR, GWM, KA, and DPS on the ROA of Islamic commercial banks.
