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

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.

Abstract

Cocoa butter is an intermediate product of cocoa processing separated from cocoa nibs or cocoa mass. Heat through cocoa processing affect the characteristic of fat including roasting process. The aim of this experiment is to evaluate the characteristic changes and sensory profile of cocoa butter in different operational roasting temperature. This experiment was conducted in Postharvest Laboratory of Indonesian Coffee and Cocoa Research Institute using dry cocoa bean from Glenmore estate in Banyuwangi (G) and from Kaliwining estate in Jember (K) in grade A according to standard of SNI 2323:2008/Amd1:2010 with moisture content of 7.5% originated from Trinitario bean and roasting temperature 120OC (T1) and 150OC (T2). Cocoa butter characteristic evaluated based on yield of separated fat, saponification, free fatty acid, peroxide value, colour and its melting profiles. Flavour description evaluated by sensory test using native panelist. Result shows nosignificant difference between roasting temperature but shows difference in appearance and flavour profile. Yield of separated fat is 35.95% per cocoa mass weight, saponification value is 193.36, free fatty acid is 0.72 and peroxide value 2.96 comply to the national standard of commercial butter. Cocoa butter appearance in T2 shows more intense of red colour than T1. Roasting temperature T1 and T2 enhance the chocolaty and nutty flavour but T2 shows burnt off-flavour for bean of Kaliwining (K). Melting point cocoa butter is 36.63OC and qualified as hard cocoa butter.

Abstract

The challenge of providing cocoa seeds is the characteristic of recalcitrant seed, thus requiring storage techniques that can slow down the decline in seed viability in an effort to manage the distribution of cocoa seeds which depend to the time of demand and harvest. The research aimed to study the effect ofpackaging method for storage of cocoa seeds; the effect of shelf life and temperature to germination and water content of seeds, and the stability of seed germination at different age and storage temperature. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, East Java. The research used complete randomized design with research design using split plot. The treatments consisted of packaging methods, storage temperature and storage life. Packaging methods consisted of two methods, i.e. vacuum methods and non vacuum methods. Storage temperature consisted of three treatments, i.e. 15OC, 25OC and 30OC. both of packaging and temperature treatments were stored at four shelf life treatment included 1 week, 2 weeks, 3 weeks, and 4 weeks. Each treatment was repeated with three replications and each treatment per replication consisted of 50 seeds. Data analysis used SAS 9.0 and stability analysis used R program and PB Tool. Water content of seeds, germination of seeds and number of seedy seeds were observed. The results showed that type of packaging and storage temperature effect to germination of cocoa seeds but did not effect to seeds water content. Storage of cocoa seeds by non-vacuum packaging showed a higher of germination compared to vacuum packaging in all temperature treatments. Storage with non vacuum packaging at a temperature 25OC showed a germination more than 85% for 2 weeks of shelf life, while storage of cocoa seeds at a temperature of 30OC had a germination of more than 85% for only 1 week shelf life. Storage of cocoa seed at 15OC showed the lowest of germination at treatment. Storage treatments did not show effect on water content of cocoa seeds.

Abstract

Drought stress can have substantial negative impacts on cocoa plant growth until affect the death of plant. The present study aimed to determine theeffect of drought stress on the some physiological characters of cacao (Theobroma cacao L.) seedlings. The research was carried out at the Indonesian Coffee and Cocoa Research Institute, Jember, East Java, Indonesia. This research was conducted from January–December 2017. The experiment was designed by using completely randomized block design with two factors and with three replications. The first factor was clones, namely ICS 60, Sulawesi 1 and KW 641 clones. The second factor was interval of watering treatment, namely watering every 2 days (control/adequate water condition), watering every 5 days (moderate stress), and watering every 8 days (severe stress). Result of this study concluded that drought stress reduced the growth of cocoa seedlings, mainly as a result of reducing photosynthetic activities in all stressed cocoa clone seedlings. Under drought stress, KW 641 and Sulawesi 1 had higher leaf area, chlorophyll a, chlorophyll b, total chlorophyll content, relative water content, and photosynthetic rate than ICS 60 clone.
