Pelita Perkebunan, Coffee and Cocoa Research Journal (CCRJ): ISSN:0215-0212 Since its establishment in 1911, Indonesian Coffee and Cocoa Research Institute (ICCRI) formerly Besoekisch Proefstation, had published its research findings through a journal call Mededelingen van het Besoekisch Proefstation. Between 1948-1981 the research institute was under the supervision of Bogor Research Institute for Estate Crops, and published its research findings through De Bergcultures which was later changed to Menara Perkebunan. Since the institute held the national mandate for coffee and cocoa commodities, and due to rapid increase in the research findings, ICCRI published its first issue of Pelita Perkebunanjournal in April 1985. Pelita Perkebunanis an international journal providing rapid publication of peer-reviewed articles concerned with coffee and cocoa commodities based on the aspects of agronomy, plant breeding, soil science, crop protection, postharvest technology and social economy. Papers dealing with result of original research on the above aspects are welcome, with no page charge. Pelita Perkebunan is managed by Indonesian Coffee and Cocoa Research Institute (ICCRI), which publish the research findings not only for coffee and cocoa but also other commodities relevant with coffee and cocoa, i.e. shade trees, intercrops and wind breakers.

Abstract

The issue of cadmium in cocoa beans has become one of the primary considerations in setting quality criteria in chocolate-consuming countries. Using rootstock genotypes that are tolerant to cadmium uptake can provide data on the absorption of cadmium into shoots for recovery. This study examined cocoa plants’ growth and physiological response to cadmium (Cd) accumulation. The research was carried out using polybags in the Greenhouse of the Indonesian Coffee and Cocoa Research Center using a half-sib family of cocoa aged 4 months after sowing. The study was designed using a completely randomized split-plot design with 3 replications. The parent plots were the half-sib families of Sulawesi 1, Sulawesi 2, and Scavina 6. The subplots were added with cadmium solution at 0 (control), 2, 4, and 8 ppm. The results showed that adding cadmium up to 8 ppm did not affect the growth and biomass of cocoa seedlings; however, it had a negative effect on plant physiological processes of the net assimilation rate and relative growth rate. Cadmium content in the tissue increased with increasing cadmium concentration in the growing medium. The accumulation of cadmium in roots was higher than that of shoots. Absorption of cadmium in the root tissue of Sulawesi 1 was higher than that of Scavina 6 and Sulawesi 2; genetic factors did not affect cadmium uptake in the shoots. There was a positive correlation between root dry weight and cadmium concentration in the tissue; the higher the dry weight of the root tissue, the higher the cadmium uptake in plants.

Abstract

Cocoa pod husk (CPH) represents an underutilized by-product of the cocoa commodity. Their utilization has been hindered by their bulkiness, high processingcost and their limited use as food ingredients. A functional and effective processing method is needed to fully optimize this commodity. This study evaluated theeffect of slicing and oven-drying treatment on the antioxidant properties of cocoa pod husk powder. A response surface methodology (RSM) was used to contour-plot the drying rate, and antioxidative properties of CPH as the effect of different treatments. A central composited design consisting of three levels of drying temperature (55, 65, and 75°C) and three levels of slice thickness (1, 2, and 3 mm) was used in triplicate. The results showed that this technique could produce CPH powder with a light-brown appearance. Drying at 51-55°C with 1-3 mm thickness produced CPH powder with high antioxidative properties. A quick-drying method with a maximum temperature of 65°C and slice thickness of 0.6 mm could also produce CPH powder with high antioxidative properties. Principal component analysis showed that 65°C might be the maximum drying temperature limit to obtain CPH powder with high phenolic. Drying method used in this study enhanced the potential of CPH powder for food ingredient due to its good appearance and high phenolics characteristic.

Abstract

Cocoa (Theobroma Cacao L.) as a plantation crop which success is determined by healthy and quality seedlings. The use of planting media with a mixture of manure and plant organic supplements may result in healthy soil because it contains soil microorganisms that are beneficial and may support the growth of cocoa seedlings. Purpose of this study was to determine the initial growth response of cocoa seedlings on various growing media and dosages of an organic plant supplement as liquid organic fertilizer. The research was conducted in February–September 2022 in a nursery located in Kradenan, Purwoharjo, Banyuwangi Regency and in Agricultural Laboratory of University of Jember, Bondowoso Campus, Bondowoso Regency. Study was carried out in a 4 x 4 factorial using a randomized block design with three replications. The first factor was planting media which consisted of four levels of treatment, namely soil + chicken manure, soil + goat manure, soil + cow manure, and soil + rabbit manure. The second factor was dose of organic plant supplement which consisted of 4 levels, namely the control treatment of 0, 50, 100, and 150 mL polybag-1. Data were analyzed using analysis of variance and follow-up tests using Duncan’s multiple range test at 5% level. Variables observed included seedling height, number of leaves, stem diameter, leaf length, leaf width, number of roots, root length, fresh weight, and dry weight of seedlings. The results showed that there was an interaction effect on all parameters except seedling height, number of leaves, and number of roots. The conclusion of the study showed that there was an effect of interaction treatment with the best treatment combination planting media using cow manure and organic plant supplement dose of 50 mL polybag-1.

Abstract

It takes three weeks to analyze the germination percentage of Arabica coffee seeds germinated using paper and a three-day water-soaking method. This 3- week period is considered too long for seed distribution to remote areas. Thus, we need to modify this germination test needs to be modified to have a shorter test time. Temperature treatment is one method to break the seed dormancy period for faster germination. This study aimed to obtain a faster and more precise method of germination test on Arabica coffee seeds. This study employed a 3 x 4 factorial complete randomized block design with three replications in which Arabica coffee varieties of Gayo-1, Kartika-1, and Sigararutang as the first factor and the temperature of the soaking water of the seeds (25 0C, 50 0C, 75 0C, and 90 0C) as the second factor. The research was conducted at the Plant Breeding Laboratory, Indonesian Coffee and Cocoa Research Institute (ICCRI), for four months. Findings showed that the interaction between treatments was only found in seed germination percentage. Soaking in room temperature water (control) for three days was better than using water at 50 0C, 75 0C, and 90 0C on the germination percentage, sprout length, and vigor index. Observations of Arabica seed germination could be shortened to 14 days compared to the standard 21-day observation. During the seedling phase, the shoot growth and root growth of the Arabica coffee seeds soaked in water at 50 0C showed no significant difference from the control. Soaking at 75 0C and 90 0C damaged the embryo and resulted in rotten seeds. Different varieties led to different germination percentages, sprout lengths, and fresh weight of seedling shoots. The method of soaking at 50 0C for 30 minutes could be used as an alternative in germination test of Arabica coffee seeds because it showed small negative effect on germinated seed and seedling quality but it shorten thetesting time for three days.

Abstract

Cocoa is the most prominent export crop in Nigeria in terms of its production and export capacities. There is dearth of literature on the profitability of the different cropping systems. This study therefore examined the profitability of the different cocoa cropping systems and the factors that affect the revenue of cocoa farmers for each of the cropping systems. The study area was Nigeria and information were collected from one hundred and eighty farmers using well-structured question- naires. Descriptive statistics, budgetary analysis and linear regression were used for analysis in this study. The study revealed that twenty-seven farmers practised sole cocoa cropping, seventy-five farmers practised cocoa/arable cropping and seventy-eight farmers practised cocoa/tree cropping systems, respectively. The mean age of farmers in sole cocoa cropping system was 49.3 years, for cocoa/ arable cropping system the mean age was 47.8 years while for cocoa/tree cropping system the mean age of farmers was 47.2 years. For sole cocoa cropping system, the total cost (TC) was USD 7,764; the gross revenue (GR) was USD 43,774 with USD 36,009 as profit made from the cropping system. The TC for cocoa/tree cropping system in Nigeria was USD 18,003, GR was USD 124,104 and the profit was USD 106,102. Similarly for cocoa/arable cropping system, the TC was USD 16,215, GR was USD 109,849 and profit was USD 93,634. The determinants for the three cocoa cropping systems were age, gender, marital status (married), educational level (primary), cost of seedling, cost of fertilizer, cost of fungicide, cost of herbicide, labour cost for bush clearing, land preparation, weeding and planting. Cocoa/tree and cocoa/arable cropping systems were more profitable than sole cocoa cropping systems. However, cocoa/ tree cropping system was more profitable with a value of USD 106,102.

Abstract

Coffee is one of the most consumed beverages in the world. It is highly consumed among many parts of India. Various studies concentrate on the effects of consuming coffee and consumer’s behavior in purchasing products related to coffee. Less studies focus on their effect among college students. Therefore, the aim of this study was to determine the coffee consumption habits and the perception of its effect among college students in Mumbai. The study was performed using convenient sampling method with a sample size of 234 students studying in different colleges from Mumbai. This study collected information about the characteristics of the students participated, coffee intake habits and the perception of its effect on consuming coffee. The majority of the students in this study consume coffee. Using factor analysis, the major factors affecting the consumption of coffee on daily basis was identified. The consumption of coffee was more during their important academic activities such as project work or examination days. Due to the burden of exams, students consume coffee to increase their study hours and academic performance.

Abstract

So far, there has been limited use of molecular markers in arabica coffee breeding program in Ethiopia. The objectives of this study were to explore the effectiveness of simple sequence repeats markers (SSRs) in detecting polymor- phism and to assess the extent of genetic diversity and relationships among ex-situconserved Arabica coffee accessions. Sixty-two forest coffee accessions planted in the experimental plot of the Ethiopian coffee breeding program were evaluated using 14 SSR markers. These markers amplified a total of 100 alleles, varying from four to ten alleles per locus, with an average of 7.2 across all loci. The rate of polymorphism ranged from 75 to 100, with a mean value of 96.4 across the accessions. The polymorphic information content (PIC) varied from 0.26 to 0.92, with a mean value of 0.70. The genetic similarity coefficient values between 72% possible pair-wise combinations ranged from 0.18 to 0.50, with overall mean value of 0.44.The unweighted pair group method with arithmetic mean (UPGMA) dendrogram based on Jaccard’s genetic similarity grouped the accessions into five main clusters and two singletons at <0.47 similarity coefficient value. These results indicate the effectiveness of the SSR markers in detecting polymorphism and the presence of a high level of genetic diversity and distant relatedness among the studied coffee accessions. The observed diversity could be exploited in the future coffee breeding program to develop heterotic hybrid coffee varieties through crossing of divergent parental lines. The highly informative SSRs markers can be also used in genetic analysis of Arabica coffee germplasm conserved in the field gene bank at Jimma Agricultural Research Center (JARC) to establish core collections for effective conservation, management and utilization purposes

Abstract

The decline in Indonesia’s cocoa production as a result of soil fertility degra dation causes fertilization to become one of effective effects. Because of that, it is possible to restore soil fertility potential by using soil fertility enhancer biochar combined with rhizobacteria consortium to create suitable conditions for plant.This research was aimed to study and investigate coconut shell biochar interacts with rhizobacteria in increasing cocoa production. This research was conducted at Kodeoha, North Kolaka, Southeast Sulawesi from September 2022 until March 2023. A split plot design with three replications each consisted of two experimental units was used as an experimental design. Biochar dosage as the main plot consisted of four levels, namely 0 ton ha-1 (control), 2.5 ton ha-1, 5 ton ha-1, and 7.5 ton ha-1 and rhizobacteria concentration as the sub plots consisted offour levels, namely 0 mL L-1, 50 mL L-1, 100 mL L-1, and 150 mL L-1. Results of this research showed a significant interaction between biochar 5 tons ha-1 and rhizobacteria 100 mL L-1 which provide best result for chlorophyll a (336 μmol m-2), chlorophyll b (150 μmol m-2), and total chlorophyll (484 μmol m-2). The interaction between biochar 5 tons ha-1 and rhizobacteria 150 mL L-1 showed the best results for number of harvested pods per tree (10.00 pods), bean weight per tree (606 g trees-1), stomata opening area (31 μm2). The interaction between biochar 7.5 tons ha-1 and rhizobacteria 150 mL L-1 showed the best results on the weight of 100 dry beans at water content 8% (159.03 g)

Abstract

Coffee flavor strongly influences consumers preference. Geographical location is one factor influencing the flavor of Robusta coffee. Descriptive sensory using RATA was used to differentiate the sensory profiles of several Robusta coffees. Sensomic approach by Principal Component Analysis (PCA) success- fully differentiated Robusta coffee from Jember Regency, East Java, Indonesia. It showed that Robusta from different growing locations has specific sensory characteristics. Robusta coffee from Gunung Malang, Tanggul, and Pakis was characterized by sweet and acid aromas, while coffee from Kemiri was characterized by sweet and sour taste, brown color, bitter aroma, and rough mouthfeel. Meanwhile Sidomulyo I and Sidomulyo II coffees, which were grown near each other and at similar altitudes, have similar characteristics, although the process was different. Both coffees have bitter aftertastes and bodies, burnt aromas, astringent flavors, and high levels of bitterness. In contrast, Robusta Rowosari, Tugusari, and Badean were characterized by low sweetness, sourness, bitter aroma, and rough mouthfeel.

Abstract

Ethiopia, the primary coffee producer in Africa and the fifth in the world is facing challenges in agricultural mechanization. The research aims to assess the status, constraints, preferences, and demand of mechanization in Ethiopia, focusing on strategies to improve smallholder access to capital-intensive inputs and bridgethe gap between mechanization and farmers’ needs. A household survey and focus group discussions were conducted on 136 random samples using a multistage procedure, with semi-structured questionnaires used to interview 81 households of small-scale and 19 households of large-scale coffee farmers. The studyfound that preferences for each operation during coffee production are based on difficulties in work drudgery, with 42.45% believing that the first energy-consuming operation is hole digging for coffee plantation and cultivation. Coffee harvesting is a highly time-sensitive operation for 49.4% of smallholder farmers, with handtools being the main implement dominantly used for weeding. Poor harvesting practices reduce the quality of coffee during processing, and some unions have two or more wet mills using old machinery. The main challenges for low mechanization in Ethiopia include difficult topography, fragmented land, a lack of manpower,lack of awareness of technology, weak linkages of coffee mechanization channels, high technology costs, a shortage of running budgets, and a weak support system of cooperatives and unions. Experts suggest that capacity building on extension systems is the best way to facilitate the extension system of coffee mechanization technology. Assessments of technology manufacturers, machine assemblers, maintenance service providers, and importers were conducted in Harar, Hawassa, Jimma, Bonga, and Addis Ababa cities. Challenges include a lack of enabling laws and incentives to facilitate business start-ups. Importation of small-scale enginedriven equipment is an additional means to meet demand in some cooperativesand may provide farmers with an alternative source of cheaper machinery. Ethiopian academics and higher education institutions are essential players in exploring mechanization options, and public and private sectors, including cooperatives and farmer organizations, need to have a clear understanding of their respectiveresponsibilities and areas for collaboration.
