Abstract

Coffee plants (Coffea sp.) are a plantation commodity that is widely cultivated in Malang Regency, East Java. This plant has high economic value and is a source of income for coffee farmers. The productivity of smallholder coffee plantations smallholder's in Malang Regency, East Java, is experiencing a downward trend, including smallholder coffee plantations in the Wajak sub-district. This is related to the condition of the sandy soil at the coffee plantation location, this sandy soil usually experiences drought in the long dry season, is sensitive to erosion and leaching of nutrients, and has a low level of soil fertility. The use of manure and lime in biopore infiltration holes (BIH) is considered to be a solution to overcome soil fertility problems in coffee plantations in Wajak Sub-District, Malang Regency. Field experiments were carried out to analyze the effects of manure and lime in BIH on soil chemical properties (Soil CEC and Exch-K) and coffee cherry yield. The experimental treatments are PO (Control), BK (Empty BIH: Biopore Infiltration Hole), KK (BIH + Goat manure 10 ton. ha-1), KP (BIH + Agriculture-lime 4.9 ton. ha-1), KKP (BIH + Goat manure 10 ton. ha-1 + Ag-lime 4.9 ton. ha-1). Each of these treatments is replicated five times in a Randomized Block Design (RBD).  Results of this research show that the combination of 10 tons. ha-1 of goat manure and 4.9 tons. ha-1 of agricultural lime added into the BIH increases the cation exchange capacity (soil CEC) by 22% and the soil exch-K content by 49.23% compared to the control treatment, and it increase coffee cherry yield significantly.

Abstract

Robusta wine coffee is a fermented product processed through multi-stage anaerobic fermentation to enhance its sensory quality through microbial activity. This study aimed to assess bacterial diversity and succession during fermentation, examine correlations between microbial populations and physicochemical parameters, and evaluate sensory attributes through organoleptic testing. Fermentation was carried out in five stages over 49 days, with bacterial isolation performed on PCA and MRS agar. Isolates were characterized morphologically, followed by Gram staining and API 50 CHL biochemical testing. Physicochemical parameters—pH, temperature, titratable acidity, moisture, and ash—were analyzed at each stage. A total of 26 isolates were recovered, with Simpson diversity index values <1, indicating dominance by certain isolates: A2, A8, A9, B4, D3, D8, and E3. Correlation analysis revealed positive relationships between bacterial counts and both moisture and pH, and negative correlations with temperature, ash, and titratable acidity. Biochemical profiling confirmed several dominant isolates as lactic acid bacteria (LAB): A9 as Lactobacillus fructivorans, B4 as L. delbrueckii, D3 as L. pentosus, D8 as Leuconostoc mesenteroides, and E3 as Lactococcus lactis. Cluster analysis based on phenotypic traits indicated strong similarity among LAB isolates, especially between D3 (L. pentosus) and the reference strain L. plantarum. Organoleptic testing demonstrated that wine coffee was preferred over non-fermented robusta, particularly in terms of aroma, acidity, and aftertaste. These results support the potential use of selected LAB isolates as starter cultures to enhance the sensory consistency and quality of wine coffee products.

Abstract

Brazil is considered the world's largest producer of coffee, requiring a large quantity of nutrients (i.e., potassium, nitrogen, phosphorus, calcium, magnesium, and others). The study monitored the spatial variability of nutrients in soil cultivated with Coffee in the region of Pompeia, São Paulo, Brazil. A grid was created with a layout of forty georeferenced points spaced 50 m apart. Soil samples were collected to determine their nutrient content. Results showed that the spatial variability of phosphorus and potassium was separated between the coffee planted in 2006 and 2017.  The acidity was influenced by the nutrient contents. There was a uniform spatial variability of calcium and magnesium due to the similar application of liming. Based on the results, we conclude that in this case study, the use of spatial variability was a great alternative to monitor the spatial dynamics of nutrients. The time of planting was classified as the main factor that influences the spatial dynamics of soil nutrient contents.

Abstract

Indonesian coffee discoveries are increasingly focusing on the optimal utilization of under-explored species such as Coffea liberica, which can be diversified into market and tourism opportunities. This study investigates the perception of expert panelists on the flavor, post-harvest practices, and tourism potential of liberica coffee cultivated in Poncokusumo. A structured Likert-scale questionnaire was administered to nine panelists, and data were analyzed using classical assumption tests and multiple linear regression. Results indicate that panelists acknowledged the distinctiveness and acceptability of liberica coffee's flavor profile, with sensory attributes such as body, balance, and sweetness significantly influencing perception (R² = 0.489). Cultivation and roasting were considered highly adaptable, with balance and coffee accession types contributing to the perception of liberica coffee’s post-harvest process (R² = 0.274). Furthermore, sensory elements such as aftertaste, aroma, body, and total score played a significant role in shaping panelists’ enthusiasm toward coffee tourism (R² = 0.576). The study highlights that sensory preferences for balance, sweetness, and light body can guide the market positioning of liberica coffee while enhancing visitor experience and supporting identity-based coffee tourism development in Poncokusumo. By linking sensory quality with experiential tourism design, C. liberica can become a niche product for sustainable rural development.

Abstract

Ethiopia, the birthplace of Arabica coffee, faces significant challenges from climate change, threatening a sector that supports over 15 million smallholder farmers. This review synthesizes research from 2010-2023, systematically sourced from Scopus, Web of Science, and Google Scholar, prioritizing peer-reviewed journals and key institutional reports. The selection criteria focused on recent studies (post-2018) and those providing specific data on Ethiopia's coffee-growing regions. The analysis reveals a historical temperature rise of 1.3°C since the 1960s, with projections of a further 1.4–2.9°C increase by the 2060s. However, a key limitation identified is the lack of localized climate models, which constrains the reliability of projections for specific agro-ecological zones. Despite this uncertainty, the consensus indicates these changes could reduce suitable coffee-growing areas by up to 60%, exacerbating pests and diseases and risking the livelihoods of 1.5 million farmers by 2050. Key adaptation and mitigation strategies—such as agroforestry, drought-resistant varieties, and renewable energy adoption—are evaluated. The review concludes by highlighting critical gaps in localized modeling and socio-economic integration, calling for urgent, targeted action to safeguard Ethiopia's coffee sector.
