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

Coffee spent ground is a primary by-product obtained during soluble coffee processing and potential to be utilized as a high value product due to its protein content. The quite popular effort to utilize protein-contained material is to process it to hydrolysate which also possess antioxidant activity. This research was aimed to study the possibility of protein and antioxidative compound from coffee spent ground by means of enzymatic hydrolysis using crude papain enzymes. Crude papain was used in different concentration ranged from 2, 4 and 6% to incubate the coffee spent grounds for 2, 3, and 4 hours and then analyzed for its protein content and its antioxidant activity, whereas response surface methodology was employed to study the tendency of the effect of incubation time and enzymes concentration towards hydrolysis results. The result showed that the use of crude papain was effective to liberate the protein and antioxidant compound the coffee spent ground with its optimum condition utilized 6% of enzyme and 2 hours incubation time. At mentioned condition, it could extract up to 67.38% of the protein of the coffee spent ground and its hydrolysate possessed relatively high antioxidant activity.

Abstract

This paper takes its point of departure from the school of thought that linkages in agricultural commodity value chains may hold the key to making actors in the chain innovative. Ghana's agricultural export sector is characterized by two main types of export: traditional and non-traditional. The traditional agricultural export sector is driven largely by the cocoa industry, while the pineapple industry represents one of the leading commodity industries in the non-traditional export sector. Using a multiple case study methodology, the paper seeks to examine how the policy environment could strengthen value chain linkages and make activities in the value chains more competitive. The study was derived from interactions with actors in the cocoa and pineapple value chains, namely input suppliers, producers, buyers, processors and some support services providers and regulatory agencies. The intention was to assemble their perceptions as interpreted in their own settings. The study showed how the existing policy on research, extension and marketing had encouraged better linkages horizontally and vertically among actors in the pineapple value chain. On the other hand, the policy underpinned by a public sector leadership in the cocoa value chain, had lowered the motivation for stronger linkages in the cocoa value chain. In terms of policy implication, the study makes a strong case for more participation of private sector actors as it is more likely to expand the platform for more interactive learning among actors for their mutual benefit.

Abstract

Breeding for cocoa resistance to VSD is the main goal in breeding program in Indonesia. Research for selection criteria on cocoa (Theobroma cacaoL.) resistance to vascular-streak dieback (VSD) has being carried out by exploring leaf stomatal characteristics corresponding to VSD damages. This research had objectives to select best crosses by observing the estimated value of heterosis and heterobeltiosis on F1 hybrid populations based on leaf stomata characteristics related to VSD resistance. Trial was established at Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute (ICCRI) in a VSD endemic area. Treatments consisted of 5 F1 hybrid populations generated by biparental crosses of TSH 858(S) x Sulawesi 1 (R), TSH 858 (S) x KEE 2 (R), TSH 858 (S) x Sulawesi 3 (R), Sca 6 (R) x KW 264 (S) and KW 617 (R) x KW 264 (S). Each cross consisted of 100-300 genotypes planted in high planting density of 0.5 m x 0.5 m. Theresistance was evaluated by scoring the plant damage in the scale of 0-3 at three years after planting. Stomata characteristics were assessed microscopically based on the variables of density, length, width and diameter of stomata and width of opening stomata. Analysis of correlation indicated that most of stomatal charac-teristicssignificantly correlated to VSD damage but the width of opening stomata performedthe highest coefficient of correlation (r = 0.49) and contributed to VSD damage (0.45). Meanwhile, path analysis indicated higher value of the char-acteristics performed less resistance of the tested hybrids, KW 617 x KW 264 showed lower value of heterosis and heterobeltiosis for the characteristics which of the best crosses for generating VSD-resistant genotype.

Abstract

Climate change and global warming have become major issues in the last 10 years and affect many sectors including coffee plantations. Global warming causes El Nino to occur more frequently and potentialy reduced agricultural production between 5–20%. In coffee plantations, an effort to minimize the impact of climate change is the use of agroforestry cropping pattern. One of the Robusta coffee producing areas grown using agroforestry system in East Java is at Gumitir mountain area. Coffee plants used as samples were 10–12 years old of Tugusari 6 coffee plantations managed by Sidomulyo farmer group. The environmental design used completely randomized block design with three replicates for each treatment which consisted of  +0.5 ha. The results of this study indicated that coffee grown under forest produced the lowest irradiation and keep daytime tem-peratures 26.33oC with humidity 85% during this El Nino period. On plant growth parameters showed that the lower intensity of irradiation produced coffee plants with morphological characters of longer segments, larger leaves and higher chlo-rophyll content. Plant growth showed no significant difference except in coffee agroforestry system with pine which produced the smallest stem diameter and fewer productive branches. It was suspected due to the presence of allelopati compounds released by the litter of pine leaves. Coffee grown under natural forest produced highest nodes per branch, cherries per node, and number of cherries per tree than other systems. Productivity of robusta coffee in Gumitir mountain area during El Nino showed that the highest productivity in forest 1497 kg ha –1 and 1355 kg ha –1 on coffee grown under Leucaena, due to its ability to maintain moisture. Agroforestry system in coffee is able to maintain environmental conditions in this case in terms of irradiation, temperature and moisture during El Nino which caused stability of plant growth and coffee productivity during El Nino.

Abstract

Many claim that commodity plantations release carbon stock and thus contribute to climate change effects. Yet, studies on cocoa carbon stock and nutrients are limited, especially in Malaysia therefore, objective of this study was to determine if there were any significant differences of carbon stock in five different tree parts of cocoa, namely branches, main stem, main roots, fibrous roots, and leaves. Twenty cocoa trees (aged 10 years old) at Kpg Muara Ahi, Serian Sarawak were destructively sampled in March, 2016, and cut into five tree compartments prior to analysis by using CHN and AAS Analyzer. Mean comparison was carried out by using one-way ANOVA SPSS 21.0 software. Total cocoa carbon stock was 27.32 M C ha -1 which branches contributing 47% from the total carbon (12.92 Mg C ha -1 ), followed by main stem (5.42 Mg C ha -1 ), taproot (4.05 Mg C ha -1 ), fibrous root (2.49 Mg C ha -1 ) and leaves (2.44 Mg C ha -1 ). Branches and main stems contained higher total carbon stock due to high total biomass (kg), how-ever, main root showed significantly (p<0.01) highest in carbon content with 42.58% in terms of per tree parts. As for the nutrient content, leaves showed signifi-cantly(p<00.1) the highest in nitrogen, phosphorus and potassium content compared to other tree parts with N 2.55 ± 0.04 ppm; P 0.20 ± 0.006 ppm and K 2.68 ± 0.24 ppm, respectively. From the study, it showed that cocoa tree does help in storing carbon. By knowing N, P and K partitioning within cocoa tree, this enable further study to be done especially in applying fertilizer for optimum yield.

Abstract

Soil fertility is an important aspect to consider in a plantation because it can affect plantation productivity. Furthermore, degradation of soil fertility issue is increasing therefore it needs innovation to improve soil fertility. Humic acid is an alternative material which can be used for improving soil fertility and supporting plantation production. This research objective was to investigate the effectivenes of humic acid for growth of coffee seedlings. This research was done in Indonesian Coffee and Cocoa Research Institute green house. Experi-ment used completely randomized design trial with two factors. First factor was the materials used humic acid, coffee pulp compost, and manure. Second factor was doses of materials: 0 g, 10 g, and 30 g per 2 kg dry soil. Research parameters used plant height, number of leaves, stem diameter, wet weight, soil carbon, N, Pavailable, K available, and pH analysis. The results showed that humic acid 30 g significant increasing plant height and K available. Furthermore, humic acid dose 10 g and 30 g resulted root, stem diameter, and leaves weight were better than compost from coffee pulp and manure. Soil carbon was increase after humic acid, compost from coffee pulp, and manure application. Humic acid, compost from coffee pulp, and manure made soil pH were stabile.

Abstract

Cocoa beans are raw materials of cocoa processed food products rich in protein and minerals. Availability of sufficient quantities greatly determines the nutritional quality of the food. One of the post-harvest processes affecting the protein and minerals contents in cocoa beans is fermentation. The purpose of this study was to determine the protein, macro, and micronutrients contents in fermented cocoa beans of PBC 123, BR 25, and MCC 02 clones with fermentation time variations for 24, 48, 72, 96, and 120 hours. Methods of analysis used Kjeldahl and Atomic Absorption Spectrophotometer. The results showed that clones, fermentation time, and their interaction affect protein, macro and micronutrients content in cocoa beans. The interaction between BR 25 clone and 48-hour fermentation time showed the highest protein content (13.34%). The highest macronutrients content were found in PBC 123 clone with 72-hour fermentation time for Ca, in MCC 02 clone with 24-hour fermentation time for Mg, in BR 25 clone with 72-hour fermentation time for Na, and in BR 25 clone with 24-hour fermentation time for K. The highest micronutrients contents were found in PBC 123 clone  with 96-hour fermentation time for Fe, in MCC 02 clone with 120-hour fermentationtime for Mn, and in BR 25 clone with 96-hour fermentation time for Zn. Variations  of protein,  macronutrients and micronutrients contents in cocoa beans were affected  by clone variety and fermentation time treatment.

Abstract

Low harvest amount of cocoa smallholder has became a great constraint for farmer in order to carry out a proper postharvest practice. Low production of raw cocoa beans cause farmers are not able to ferment their cocoa beans that lead to low quality of cocoa beans produced. Addition of starter culture to improve the fermentation performance has been previously reported by some researchers. In this study,  Lactobacillus fermentum(LF) inoculum was used as stater culture for small scale cocoa fermentation (15 kg). The LF culture (107 CFU/gr) was added in several concentration (1, 2.5, and 5% w/w) prior cocoa fermentation. The fermen-tation was carried out in 4 days (96 h) with once turning in 48 h. The result showed that the addition of LF in small batch of cocoa fermentation could improve the performance of fermentation and resulted in higher amount of fermented cocoa beans (70,34%, 5% LF) compared to natural fermentation and fair average quality (FAQ) beans (45% and 41%, respectively).  This research result is significantly important solving the issues of fermentation concerning with minimum quantity of cocoa needed. With this approach, small batch of cocoa fermentation even could result in comparable quality to full-batch fermentation.

Abstract

Development of household coffee industry can be used as a strategy to redistribute farmers’ household income. Through production process, farmer can create value-added by producing high value commercialized products. The objective of this research were to assess coffee price dynamics in Pasuruan district; and to analyze the value-added of coffee products produced by farmers. This research was carried out in Pasuruan district including Prigen, Tutur, Purwodadi, Purwosari, and Puspo sub-districts. Respondents were selected by using snowball  sampling method as much as 16 farmers. Data used in this research preferred primary data with secondary data as a supporting data. Data were analyzed with descriptive analysis, inductive analysis, and Hayami method. The results showed that the average of farmer’s share in Robusta coffee sales had exceeded 80% of the international market and Lampung spot market.  meanwhile, the average of farmer’s share in Arabica coffee sales was more than 40% of the international market and Medan spot market. Higher value-added could be created by conducting downstream processing as one of product diversification activities. Robustaand Arabica coffee which had been marketed as roasted coffee and ground coffee would provide a higher value-added than that of primary products (cherries, dried cherries, green bean). Based on these cases, farmers could gain the highest value-added by marketing ground coffee products.
