Abstract

General Background: Rubber productivity in Indonesia remains low due to suboptimal cultivation practices, including the improper use of stimulants, which can harm plant health. Specific Background: One strategy to increase yield is the application of low tapping frequency combined with Ethrel 10 PA stimulant, which can prolong latex flow and enhance cell metabolism; however, its effectiveness depends on clone type and plant physiological condition. Knowledge Gap: Limited knowledge exists on the optimal combination of tapping frequency and stimulant dosage to sustain productivity without compromising plant health, particularly for PB 260 and GT 1 clones. Aims: To determine the optimal tapping frequency and stimulant dosage for these clones. Results: Field trials revealed that a d/3 tapping frequency yielded the highest latex output, while a dosage of 2 g/tree produced the maximum yield; however, there was no significant interaction between the two factors. High tapping frequency, though productive, risks reducing plant health. Novelty: This study recommends tapping every four days combined with a 1 g/tree Ethrel dosage to balance productivity and plant health. Implications: These findings provide practical guidance for sustainable rubber cultivation, maximizing yield while preserving the productive lifespan of trees. Highlights: Optimal combination of tapping interval and stimulant dosage. Balances high yield with plant health preservation. Practical recommendation for sustainable rubber farming.

Abstract

Background (General): Islamic banks play a crucial role in Indonesia’s financial system, with murabahah financing serving as a primary income source. Background (Specific): While murabahah margins are fixed and independent of interest rate fluctuations, macroeconomic variables such as interest rates and inflation may still indirectly affect bank profitability. Knowledge Gap: Previous studies largely focused on annual pre-pandemic data, overlooking quarterly dynamics during the post-pandemic period, when monetary and market conditions changed significantly. Aim: This study examines the effects of murabahah financing, interest rates, and inflation on murabahah margin income in Indonesian Islamic banks during 2020–2024 using quarterly data. Results: Multiple regression analysis of 30 observations from six banks shows murabahah financing has a significant positive effect on margin income, whereas interest rates and inflation show no significant individual impact. Jointly, all three variables significantly influence margin income. Novelty: The research introduces a post-pandemic, quarterly dataset and simultaneously tests three key financial and macroeconomic variables in the murabahah context. Implications: Findings affirm the strategic importance of murabahah financing as a stable revenue driver, suggesting Islamic banks should prioritize financing expansion and operational efficiency over short-term macroeconomic fluctuations when formulating pricing and portfolio strategies.Highlight : Murabahah financing has a significant positive effect on margin income. Interest rates and inflation have no partial effect. All three variables have a simultaneous significant effect.
