Abstract

This study developed a green decaffeination method for Dampit Robusta coffee using crude pineapple bromelain extract. A factorial design (enzyme concentration: 40-80%; time: 4-12 h) optimized the process, evaluated by UV-Vis spectrophotometry. The treatment with 80% enzyme for 12 hours reduced caffeine content by 95.8%. A multiple linear regression model (R² = 0.9404) confirmed the significant synergistic effect of concentration and time. FTIR spectroscopy revealed the mechanism, showing proteolytic alteration of the Amide I band (1637 cm⁻¹) in the enzymatic sample, absent in a commercial decaf. This indicates bromelain hydrolyzes bean proteins, facilitating caffeine diffusion. Furthermore, anomalous peaks (e.g., 2171 cm⁻¹) in the commercial sample suggested non-native residues, highlighting a purity advantage of the enzymatic method. Organoleptic analysis indicated a trade-off, where the most effective treatment compromised sensory attributes, while a moderate condition (60%, 4h) maintained acceptability. The work establishes a sustainable decaffeination framework and demonstrates FTIR's utility as a diagnostic tool for process verification and residue screening in food biotechnology.

Abstract

This study aimed to analyze the diversity and ecological roles of soil insect communities in coffee (Coffea sp.) agroforestry systems in Purwodadi, Pasuruan, East Java. The research focused on identifying insect composition, abundance, and functional roles in supporting ecosystem processes. Sampling was conducted in September 2021 using pitfall traps arranged along transects within a one-hectare coffee agroforestry area characterized by diverse shade trees, including Swietenia mahagoni, Ficus benjamina, Mangifera indica, Ceiba pentandra, Leucaena leucocephala, Musa paradisiaca, Syzygium aromaticum, and Magnolia alba. Soil insects collected were identified to genus level, and ecological indices were calculated, including Shannon-Wiener diversity (H’), Simpson dominance (D), evenness (E), and Margalef richness (R). The results recorded 12 genera from 9 families comprising 204 individuals. Formicidae and Gryllidae were the most dominant families, with Brachyponera (73 individuals) and Gryllus (36 individuals) showing the highest abundance. Ecological indices revealed moderate diversity (H’ = 1.868), low dominance (D = 0.203), relatively high evenness (E = 0.752), and low species richness (R = 2.068). These findings highlight the crucial roles of soil insects as decomposers, herbivores, predators, and soil aerators, emphasizing their importance in sustaining nutrient cycles, regulating pest populations, and maintaining soil ecosystem stability in coffee agroforestry systems.

Abstract

Coffee contains some bioactive compound that has benefits for some health issues. Trigonelline, diterpene cafestol, chlorogenic acid, and caffeine are bioactive compounds found in coffee. We investigate some bioactive compounds in coffee, which could protect from Alzheimer’s disease (AD). Amyloid beta Protein Precursor (APP) plays a role in the accumulation of amyloid toxicity, contributing to the neurodegenerative disorder of AD. This study aims to investigate the potential of four bioactives in coffee that could mitigate the risk of AD by inhibiting APP based on its interaction and binding affinities through an in-silico study.  The method includes the prediction of protein use PHYRE2 and small-molecule structures, and visualization with Discovery Studio, molecular docking using Autodock Vina with PyRx 8.0, and analysis of the bioavailability of bioactives using SwissADME. Chlorogenic acid has the highest binding energy compared to other ligands to interact with APP (-6.7 kcal/mol), whereas the other ligands have binding energy scores -4.7 kcal/mol, -6.5 kcal/mol, and -4.5 kcal/mol. However, diterpene cafestol is a promising compound for drug development based on its binding site, bioavailability, high gastrointestinal absorption, drug likeness score of 0.55, and its binding energy score -6,5 kcal/mol, making it a top candidate.

Abstract

Flash floods that struck Bumi Aji, Batu City, in 2021 were a direct consequence of environmental degradation, primarily the loss of water catchment areas due to land-use change and must restoration strategy. This study aims to: (1) analyze the decline in canopy density using Geographic Information System (GIS) and the Normalized Difference Vegetation Index (NDVI), (2) assess the impact of this decline on flood vulnerability, and (3) formulate a strategic mitigation model with coffee agroforestry. Through a time-series analysis of satellite imagery (<2000 to 2020), the research identifies significant land degradation, particularly on the northern slopes of Mount Arjuno, where vegetation cover decreased by approximately 40% due to agricultural expansion. This reduction diminishes water infiltration and increases surface runoff, heightening flood risk. In response, this paper proposes a strategic shift to coffee-based agroforestry as a sustainable land conservation model. This approach directly restores a multi-layered canopy, which improves soil structure and reduces erosion. Furthermore, it offers economic resilience for local communities through diversified income. Implementing coffee agroforestry is presented as a synergistic strategy that aligns with Bumi Aji's agrotourism potential while effectively mitigating future flood disasters through ecological restoration.
