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.

Abstract

Cayenne pepper (Capsicum frustescens L.) cultivation faces several problems, including acidic pH and inadequate nutrient management. These problems can be addressed by using a mixture of various ameliorants and AB mix nutrient solutions. This study aimed to determine the effect of ameliorant mixture dosage and AB mix solution concentration on soil chemical properties, growth, and yield of cayenne pepper. The experiment used a randomized block design, consisting of two factors: nutrient solution concentration and ameliorant dosage. The factor of nutrient solution concentration consisted of four levels, i.e., 700, 1000, 1300, and 1600 ppm, while the factor of ameliorant dosage also consisted of four levels, i.e., 0, 2, 4, and 6 t ha-1. Observations were made on soil chemical properties, namely soil pH, organic carbon content, and cation exchange capacity (CEC). The agronomic characteristics observed were plant height, number of leaves, leaf area, chlorophyll content index, fruit length, number of fruits, and fruit weight per plant. The results showed no interaction between the concentration of AB mix solution and the ameliorant dosage on soil chemical properties, growth, and yield characteristics of cayenne pepper plants. The single effect of AB mix solution or ameliorant was observed on the number and weight of fruits per plant. The optimal dose for achieving the maximum harvested fruit weight was 6 t ha-1 of the ameliorant mixture (76.55 g pepper/plant), while the optimal AB mix concentration was 1600 ppm (65.02 g pepper/plant).

Abstract

Indonesian rice production has been unable to fully meet national demand, partly due to weed competition, which can reduce rice yields by up to 80% if left uncontrolled. This study aimed to evaluate the effectiveness of pre-emergence herbicides containing pretilachlor (300 g/L) and post-emergence herbicides containing cyhalofop + ethoxysulfuron (330 g/L) for weed control in direct-seeded rice, and  to determine the optimal dosage. Herbicides active ingredient is pretilachlor are a category of pre-emergence herbicides used in rice cultivation; these herbicides are systemic and are used to control sedges, grasses and broadleaf weeds. The cyhalofop + ethoxysulfuron herbicide is a post-emergence herbicide mixture that can suppress the growth of sedges, broad-leaved weeds and grasses . The study was conducted at PT. Syngenta Indonesia R&D Cikampek Site from August to December 2024, using a Randomized Group Design (RGD) with four replications and six treatments, namely two doses of pre-emergence herbicide (1.0 and 0.5 L/ha), two doses of post emergence herbicide (1.0 and 0.5 L/ha), manual weeding, and control (without treatment). The parameters observed included the weed vegetation analysis, dry weight of weeds, and the components of rice plant growth and yield. The results showed that pre-emergence herbicides with the active ingredient pretilachlor 300 g/L  and post-emergence herbicides with the active ingredient mixtures of cyhalofop + ethoxysulfuron 330 g/L  are effective in controlling various important weeds in the direct seeding system of rice cultivation, such as Cyperus iria, Echinochloa crus-galli, Fimbristylis miliacea, and Leptochloa chinensis, thus helping rice plants grow optimally and increasing yields. Pre-emergence herbicide with the active ingredient pretilachlor 300 g/L  at a dose of 1.0  L/ha gave the best results in suppressing weed growth and increasing rice yields compared to other treatments.

Abstract

Strawberry (Fragaria × ananassa) ‘Haruhi’ is a subtropical plant that is being cultivated in Indonesia. High temperatures in tropical climates could decrease strawberry yield and fruit quality. The purpose of this study was to evaluate the effect of light, melatonin, potassium fertilizers, and their interactions on the yield and fruit quality of ‘Haruhi’ strawberry. This research was conducted from April to June 2024 at the Bale Tatanen, Faculty of Agriculture, Universitas Padjadjaran. A split-plot design was used, with lighting treatment as the main plot and melatonin and potassium fertilizer treatments as the subplot. Lighting treatments consisted of supplemental LED lighting and natural light (non-LED). Subplot treatments included control, 100 μM melatonin, 2 g L⁻¹ potassium fertilizer, and their combination. The results showed that the combination of non-LED lighting with melatonin and potassium fertilizer produced the best fruit diameter and fruit weight. Under non-LED lighting, melatonin treatment resulted in the highest total soluble solids, while the control treatment produced the highest number of flowers. The interaction between LED lighting and melatonin resulted in the highest fruit number. Non-LED lighting alone also produced the best plant height, leaf number, and fruit length. Potassium fertilizer alone resulted in the highest leaf number, while the control treatment produced the highest plant height.

Abstract

Tea productivity is strongly influenced by agronomic management practices, particularly fertilization and pruning, which play critical roles in regulating plant growth, physiological performance, and shoot regeneration. This review aims to synthesize current scientific evidence on how integrated fertilization and pruning management can sustainably enhance tea productivity. A narrative review approach was employed by collecting and analyzing peer-reviewed articles published between 2015 and 2025 from reputable databases, including Google Scholar and major international journals. The review highlights that balanced fertilization strategies, combining inorganic, organic, and biofertilizers, significantly improve nutrient availability, photosynthetic efficiency, and shoot yield. Pruning, when properly timed and executed, stimulates vegetative growth, maintains canopy structure, and optimizes the distribution of assimilates. Several studies demonstrated that microbial-based biofertilizers enabled a 25% reduction in inorganic fertilizer inputs without compromising tea shoot yield, while optimum pruning cycles of four to five years-maintained productivity and canopy renewal. In addition, the proportion of pecco shoots was reported to decline from approximately 70% in the first year after pruning to 19% in the fourth year, emphasizing the importance of proper pruning management.  Importantly, the integration of fertilization and pruning practices produces synergistic effects, resulting in enhanced shoot density, improved yield stability, and long-term sustainability of the plantation. This review emphasizes that integrated nutrient and canopy management is essential to address productivity decline and environmental challenges in tea plantations, providing a scientific basis for developing climate-resilient and resource-efficient tea cultivation systems.
