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

Cocoa is a sensitive plant to availability of soil water. The availability of water affects the formation of cocoa pods and beans. The aim of this research was to determine the genetic diversity and the influence of season on the diversity of cocoa beans quality as well as determining the pattern of genotype and season interaction on the quality of physical physiology of cacao beans. The research was conducted in Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember during dry season (2015) and rainy season (2016). This study used a complete randomized block design 2 x 12 factorial and three replicates as blocks. The first factor was the season consisting of two levels namely, dry season and rainy season. The second factor was cocoa clones, TSH 858, KW 084, KEE 2, Sulawesi 1, Sulawesi 2, BAL 209, KW 215, JTC 5A, JTC 5B, KC 2, KKM 22,and KJ 2. Observation variables included pod diameter, pod length, pod weight, dry bean weight, number of good beans/pod, number of empty beans/pod, numberof beans, and number of pods/tree/season. Data was analyzed using ANOVA fixedfactor. The bean dry weight characteristics possesed a low genetic diversity (0.27%) whereas the physical quality character of other beans, i.e bean count had moderategenetic diversity (14.20%). Meanwhile, the real difference was shown on the dry weight of bean characteristics. The best dry bean weight was observed during the dry season. Clones KW 215 and Sulawesi 1 in the dry season was catego-rized in grade A, while the lowest quality JTC 5A with grade D. The interaction of genotype (clone) with the environment (season) resulted in a significant effect onpod diameter character, pod weight, bean count, dry bean weight, and numberof pods/tree. Based on the biplot AMMI graph it was known that the TSH 858 clone showed genetic stability in bean count character. As for the character ofthe number of pods/tree, clones KKM 22, BAL 209, and KW 084 had the stability of the number of pods in rainy and dry seasons. Clones KJ 2 and Sulawesi 2 showed season-specific in the dry season for the number of pods/tree characters.

Abstract

Global climate change is impacting cocoa cultivation that cocoa trees must be adaptive in dry climate and higher temperature of environmental condition. This research had objective to observe adaptability performance of the promising hybrids of cocoa  ofthe selecting high yielding hybrid swhichare  tolerantto dry condition. Treatments were 14 hybrids of bi-clonal crosses betweenselected clones in factorial design in which KEE 2 was selected based on its resistance to vascular-streak dieback (VSD) and drought condition. Multilocation trials were established in Kaliwining Experimental Station in Jember (low land) and Sumber Asin Experimental Station in Malang (medium land) both of which were classified to dry land area. Yield per tree were assessed in monthly basis during 9 consecutive years of yield period. Data were performed to the combinedanalysis of variance followed by AMMI (additive main effect and multiplicative interaction). The results showed thatthe factor of hybrid, location, and interactionof hybrid and location to year contributed higher value of variance for the yield. Analysis of AMMI indicated that the hybrids of KEE 2 x Sulawesi 1 (F 1 and reciprocal) had highest yield potency and adaptive to low land (Kaliwining) on the other hand the hybrids of TSH 858 x KEE 2 (F 1 and reciprocal) were adaptive to medium land (Sumber Asin). Refer to yield adaptability to dry condition and other potential traits reported thus the hybrid of KEE 2 x Sulawesi 1 (F 1 and reciprocal) was released as cocoa planting material for addressing dry condition. The result also identified those hybrids inherited using KEE 2 performed more adaptive to dry condition. Further-more, the clone was suggested to be used as parental clone on breeding for drought tolerance.

Abstract

Economically, cacao bean products are divided into fine flavor and bulk cocoa. Fine flavor cocoa has white color beans while bulk cocoa has purple color beans. Bean color of fine-flavor cocoa beans is determined by the presence of a double recessive gene which is inherited from Criollo cocoa type. Analysis of the genetic background in this study used maturase K (matK) gene to ascertain the identity of the genotypes which will be used as a parent in crossing of fine flavor cocoa plants. The study aimed to investigate the genetic background of the promising clones that will be used as a parent in breeding program on fine flavor cocoa based on maturase K (matK) gene in order to ensure the identity of the genotype that will be used in parent crossing and it had Criollo ancestor. DNA analysis was conducted at Agency for the Assessment and Application Technology (BPPT), Serpong, West Java. DNA analysis was conducted on eight genotypes consisting of four genotypes of fine flavor cocoa (ICCRI 02, DRC 16,  PNT 16 and DR 2) and four genotypesof bulk cocoa (MCC 01, MCC 02,  sulawesi 1,  and KW 617).  The results showed that Maturase K (matK) was one of chloroplastgene which could be used to study phylogenetic and evolution on cocoa. Two primers Mac 02 and Mac 09 were used for amplification of matK gene on cocoa with a rate of homology 99-100% with position 872 bp for Mac 02 and 1153 bp for Mac 09.The results of the phylogenetic analysis showed that the cocoa genotypes would be used as parent crossing included DR 2, ICCRI 02, DRC 16, PNT 16, MCC 01, MCC 02, Sulawesi 1, KW 617 and HJ 2 tended to have ancestral Criollo as female parent.

Abstract

Currently, vascular streak dieback (VSD) attacks have widespread in areas ofthe center of cocoa (Theobroma cacaoL.) production, especially inSulawesi. Salicylic acid and benzoic acid are part of phenol compounds reportedlyacts as bioimmunoregulator in increasing of plant resistance to that pathogen. The objec-tiveof this research was to investigate effect of exogenous salicylic acid and benzoic acid applications to VSD disease attack on cocoa seedlings.  The research was conducted at Indonesian Coffee and Cocoa Research Institute,Jember, East Java.  This experiment designed using randomized completely block  design with three replications. The treatments included concentrations of salicylic  acid in 0.5 mMol, 1 mMol, 2 mMol; benzoic acid with concentration 0.5 mMol, 1 mMol,2 mMol; and control (water spray). Observations were based on the incidence and severity damage  of disease, plant height, stem diameter, number of leaves, stelate trichome, chlorophyll, width and length of stomatal apperture, and number of stomata. Exogenoussalicylic acid and benzoic acid as phytohormone can reduce disease insidence and severity of VSD. In conclusion, our results indicated that exogenous salicylic acid and benzoic promoted stomatal closure in cocoa leaf by decreasing width-stomatal closure. Salicylic and benzoic acid had no effect to plant height, stem  diameter, number of leaves, length of stomatal apperture, number of stomata, and number of stelate trichome.

Abstract

Biodiversity can be studied at a species level such as insect group. Insects play important roles in the ecosystem which is affected by the climate factors such as rainfall pattern, humidity and temperature. Changes on this climate pattern might give direct and indirect impacts on the insect activities as the global trend of climate showed a warmer effect which has caused the glacier to melt faster withless ice coverage, the rise at the sea level and the global temperature continues to rise in the future. Glacier has lost ice coverage tremendously. The sea level also reported rise up and the temperature predicted continuously increased. This study was carried out at Cocoa Research and Development Centre (CRDC) Madai, Sabah, Malaysia. The objective of this study was to examine the impacts of weather pattern changes on the insect composition in the last 11 years. This study was carried out at three different areas using four different insect trapping methods such as pitfall trap, winkler trap, line transet trap and light trap. Result from this study showed that the insect composition has changed drastically in the last 11 years.  Reduction in number of insect catched using 4 different methods has suggested that the changes in weather pattern over period of time have some effects on insect composition.

Abstract

A study on the potential of  Trichogrammatoidea bactrae fumata  (Tbf) parasitization in the field was conducted at an insecticide-free cocoa cultivation namely Treblasala Plantation, Banyuwangi, East Java. The research design used was a factorial randomized block design with three replications. The tested treat-ments consisted of parasitoid release intervals (once in 2 and 4 weeks) and the release population of 0 (control); 25,000 and 50,000  Tbfper hectare per release. Observations were made on number of detected eggs and parasitized eggs, and level of cocoa damage caused by cocoa pod borer (CPB) attacks. The results of  this  research showed that parasitization level of  T.  bactrae fumata  on CPB eggs after3 months of the release ranged from 29.81–42.79%. The parasitoid release of CPB eggs (T. bactrae fumata) in the field for a year showed that the parasitiza-tion  level of CPB eggs in the field ranged from 17.78–29.72%. Nevertheless, during that year, there was no significant effect of parasitoid release on the suppression of yield loss due to CPB attacks in the field.

Abstract

Roasting is an important coffee bean processing that affect quality and flavor consistency. Roasting parameters are summarized in the roasting profile which describe density, water content, pH, yield, taste, time and temperature as well as roasting technique of the beans. Roasting profile which is important for roaster master varies according to coffee bean types, such as Arabica and Robusta collected from specific area. Therefore, this paper studiedthe process of roasting Robusta coffee beans collected from Sumber Asin, Malang with normal roast technique using roaster machine in order to get taste consistency with determining optimum point from these parameters. During roasting process, temperature changes were recorded every two minutes for 20 minutes after temperature reached 180 OC. Density, moisture content, yield, pH, and flavor were assessed after roasting. The normal roasting technique required optimum roasting time of 9-10 minutes at 180 ± 5 OC, density value of 0.49 ± 0.04 gram/ml, water content of 3.5 ± 1.3%, losses 9.7 ± 1.9%, pH 5.3 ± 0.2, with chocolaty, spicy, and thick body flavors. There was strong correlation between Robusta roasting profile with all parameters measured. The optimal Robusta roasting time could be determined from intersec-tion  line between temperature and density in the roasting profile. Robusta optimum roasting time is about 10 minutes. The roaster master could use optimum roasting time in accordance to roasting quality.

Abstract

Cocoa production in Nigeria has been on a downward trend in recent years. Low productivity from ageing cocoa trees and low technology uptake among the farmers are some of the contributing factors. Efforts are therefore ongoing to introduce cocoa hybrid technology to enhance cocoa farmers’ productivity. This study therefore examines factors influencing adoption of CRIN TC (TC 1- 8) cocoa hybrid technology among cocoa farmers in Oyo state, Nigeria. Using multi-stage sampling procedure, 80 respondents were sampled for the study. A well-structured questionnaire was used to gather information from the farmers. Data was analysed using descriptive statistics and regression analysis. The results revealed that most (83.8%) of the farmers were male with the mean age of 55 years. It also showed that 43.8% of the farmers completed primary education while majority (51.3%) had a household size of 6-10 persons with a mean household size of 5 persons. The study also showed that 80% of the cocoa farmers got their information regarding cocoa hybrid through research institute. It was also found that most of the farmers had high level of adoption. Meanwhile, high cost of agrochemicals was identified as a major constraint toward adoption of CRIN TC (TC 1- 8) cocoa hybrid. Meanwhile, farmers age (β=-0.007) farming experience (β=-0.004) were identified as the factors influencing farmers’ adoption of the cocoa hybrid. Governments at various levels are encouraged to subsidise the price of agrochemicals which was discovered as major constraint to adoption of CRIN TC (TC1-TC8) cocoa hybrid technology.

Abstract

Shade-trees with energy use in coffee plantations are an important alternative to increase profitability in groforestry systems. The aim of this study was to investigate gross calorific value (GCV) of 15 shade-tree species in coffee plantations in Costa Rica. The relationships between specific gravity and extractives content on GCV was evaluated. The results revealed that GCV varied from 15.9 to 21.9 MJ kg-1 for sapwood, and from 15.3 to 21.9 MJ kg-1 for heartwood. No consistency was observed regarding to relation of type of wood (sapwood orheartwood) and GCV. The highest GCV value was found in Pinus caribaea for sapwood and heartwood. However Cupressus lusitanica, presented high GCV in sapwood too. The lowest values were found in Schizolobium parahyba in sapwood and Zygia longifolia and Eucalyptus globulus in heartwood. Carbon content (C) and carbon/nitrogen ratio (C/N ratio) and extractives in sodium hydroxide and dichloromethane were correlated with GCV in sapwood and heartwood. Meanwhile extractives in hot water were correlated in heartwood, and nitrogen content (N) and extractives in cool water were too correlated in sapwood.
