Abstract

Indonesia's cocoa production has experienced instability in recent years, highlighting the need to improve productivity through intensification and extensification strategies. The success of these approaches is highly dependent on the availability of high-quality seedlings. Therefore, the utilization of coconut water as a natural plant growth regulator and supplementary nutrient source has potential to enhance cocoa seedling growth. This study aimed to evaluate the effects of different doses and application frequencies of mature coconut water applied as a foliar spray on cocoa seedling growth and to determine the most effective treatment combination. The experiment was conducted from December 2025 to May 2026 at the Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, located at an altitude of approximately 752 m above sea level. A Randomized Block Design (RBD) consisting of ten treatments and three replications was employed. Treatments comprised combinations of mature coconut water doses of 10, 15, and 20 mL plant⁻¹ applied at intervals of 7, 14, and 21 days, while a 0.2% urea treatment served as the control. Observed variables included plant height, stem diameter, and leaf number. The results showed that foliar application of mature coconut water significantly increased cocoa seedling stem diameter at 6–10 weeks after treatment. In addition, variations in coconut water dose and application frequency were able to support plant height and leaf production with effectiveness comparable to that of the inorganic fertilizer treatment (urea). For stem diameter, the application of 10, 15, and 20 mL plant⁻¹ resulted in significantly greater values than the control treatment. Among the tested application intervals, the 21-day interval was found to be the most effective.

Abstract

Coffee (Coffea arabica) is a globally significant beverage whose sensory profile and physiological effects derive from a complex matrix of secondary metabolites. This review presents a comprehensive "lifecycle" perspective of three pivotal classes: the alkaloid caffeine, phenolic chlorogenic acids (CGA), and the diterpenoids cafestol and kahweol. Here, 'lifecycle' defines a metabolite's continuous biochemical trajectory, tracking its genetic origin and ecological function in the plant through structural modifications during fermentation, drying, storage, and roasting. These classes are highlighted because they serve as the primary drivers of bitterness, acidity, and health bioactivities with fundamentally distinct transformational pathways. Following a systematic methodology, this study traces these compounds from biosynthesis to their fate during post-harvest processing. The synthesis reveals that post-harvest interventions cannot create quality but only modulate the bean's inherent chemical potential established by genetics and agronomy. Specifically, fermentation primarily reshapes hydrophilic phenolics (CGA) via hydrolysis to soften astringency, whereas roasting acts as a thermochemical trigger that degrades labile CGA into sensory critical melanoidin precursors and liberates insulated lipophilic diterpenoids. Current literature frequently compartmentalizes pre harvest plant omics and post-harvest food chemistry. This review addresses this gap by integrating these disciplines into a continuous mechanistic model, demonstrating how botanical origins inherently precondition processing outcomes. This holistic perspective offers practical insights for agronomists, processors, and roasters to predict, preserve, and intentionally enhance the sensory and bioactive profile of coffee across the supply chain.
