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

Self-incompatibility is an important factor in limiting the yield of cacao (Theobroma cacao L.). The research aimed to study the effect of self-compatibility on cocoa related to pod and bean characteristics and seedling performance. The research was conducted at Kaliwining Research Station, Indonesian Coffee and Cocoa Research Institute, Jember and Bogor Agriculture University in Bogor. The research used completely randomized design with three clones as treatment and each treatment repeated three times. The three clones used had a different self-compatibility characteristics; NA 32 (self-incompatible), DR 2 and Sulawesi 2 (self-compatible). Fruit set, pod characteristics, bean characteristics and seedling performance were observed. The results showed that self compatible cocoa clones had higher of fruit set per cushion (4,7-7,9 fruit set per tree) than selfincompatible (1,9 fruit set per cushion). Sulawesi 2 as a self compatible cocoa clone showed the lowest of fallen fruit set per cushion after two and four weeks. Self compatible cocoa clones (Sulawesi 2 and DR 2) had greater pod and better bean quality than self incompatible (NA 32) included pod length, pod weight, pod girth, weight of wet beans per pod, number of beans per pod, volume per wet bean, weight of dry bean and weight of nib. While number of poorly beans per pod in self incompatible showed higher than self compatible clones. Seedling performance of self compatible showed better than self incompatible for plant height and stem diameter. Visually the seedling of self compatible showed homogeny than self incompatible and variant analysis of plant height showed that self compatible were lower than self incompatible.

Abstract

Global warming impact in increasing temperature and becomes threat for cocoa production because growth of cocoa depends on the amount of water available in the environment. The objective of this study was to describe cocoa hybrid that may potentially be developed as drought-resistant cocoa hybrid. The study used 14 types of cocoa hybrids and ICCRI 06H as control. Those plants were approximately 4 years old and the hybrids were planted in Sumber Asin Experimental Station and Kendeng Lembu Plantation. The variables being observed to evaluate 2015 El-Nino effect were percentage of growing plants, tree diameter, jorquette height, flush and flower intensity in 2016. Analysis of variance, correlation and additive main effect and multiplicative interaction (AMMI) biplot were used to find out which hybrids were potentially drought-resistant. The finding showed that there was significant interaction between the genotypes (hybrids) and environment towards the percentage of growing plants, tree diameter, flush and flower intensity. The correlation between the variables showed that there was significant, negative correlation between the percentage of growing plants and height; even though there was significant correlation between the two, it was quite low. There was significant correlation between the tree diameter and the jourquette height while there was not any between the tree diameter and the percentage of growing plants. The AMMI analysis classified the drought tolerant hybrids into two groups, (1) cocoa hybrids adaptive to both normal as well as the temperature and water scarcity (drought), was ICCRI 03 x KW 617, and (2) drought tolerance cocoa hybrids, was KW 516 x KW 617.

Abstract

One of factors that affects the success of a plant cultivation using somatic embryogenesis method is the formation of somatic embryos from embryogenesis callus. This research aimed to study the effect of sub-culture period on quality and quantity of the somatic embryos of Coffea arabica. This research used explants of somatic embryos of Arabica coffee obtained from the leaves of 2K Andungsari clone. The embryos were taken during embryogenes is callus phase using Murashige-Skoog culture media added with B5 vitamin and auxin hormone (2,4dichlorophenoxy acetic acid) 0.5 mg/L and sitokinin (benzyl amino purin) 1 mg/L. Observation on somatic embryos obtained from the sub-culture period of 3, 6, 9, 12 and 15 weeks. The parameters observed in this study included quantity and quality of the somatic embryos during each sub-culture period. Observations on quantity of the somatic embryos were conducted based on number of embryos per cluster, while quality was measured from the percentage of normal embryos, histological analysis, and morphological measurement on weight and size of the normal embryos. The result showed that the best quantity of somatic embryos was obtained from the sub-culture period of nine weeks with 18.4 somatic embryos per cluster. The best quality embryos were also obtained in the sub-culture period of nine weeks with the percentage of normal embryos 71.4%. Histological analysis carried out on the somatic embryos obtained from sub-culture of three weeks period showed that the cells of the embryos were formed by living and solid cells which nucleus were clearly seen in the center of the cell, indicating that the embryos were formed by young tissues. Data of morphological parameters showed that normal embryos during the sub-culture period 3 to 15 weeks weighed around 0.23–0.78 mg and length of around 0.18–0.25 cm. The data can be used to predict number of explants and required time to produce certain number of normal embryos

Abstract

ENSO (El Nino Southern Oscillation) occurring in 2015 in Indonesia caused drought stress and the decrease in the percentage of production and even death of plants. One effective and relatively inexpensive way of reducing damage and economic losses due to drought is the availibility of tolerant cocoa. The objective of this research was to obtain tolerant clones based on morpho-physiological characters under drought stress. The experiment was conducted in Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute (ICCRI) during dry season (El Nino period with 5 consecutive dry months, from May to October 2015). Stomata, proline, leaf water status was measured at the peak of dry season on tested cocoa clones. The cocoa clones that predicted tolerant against to drought stress were KW 641, KW 514, KW 535, KW 619, and KW 516, whereas the cocoa clones that predicted susceptible under drought stress were KW 609, KW 614, KW 635, KW 606, and KW 651. The treatment clones had higher values of RWC, leaf proline content, narrower width and length of stomata openings, but smaller value of WSD compared to susceptible clones. Meanwhile, the character of leaf thickness might not significanly different to the character of drought tolerance.

Abstract

Coffee berry borer (CBB), Hypothenemus hampei Ferr. (Coleoptera, Scolytidae) is generally controlled by applying integrated pest management, particularly through sanitation and using biological agents. Beauveria bassiana is wellknown as an entomopathogenic fungus, which has been proven to be the most effective and prospective agent that could be developed to control CBB. Dissemination of microbial biocontrol agents via insect or predators may has advantages for safe spore dispersal to targeted pests with the added benefit of predation. The research with aim to determine if spores of B. bassiana can be picked up by CBB from disseminated containers had been conducted at Plant Protection Laboratory and Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute. Ten infected coffee berries and ten CBB adults were sprayed with various concentration of B. bassiana suspension, and then infested them in 10 healthy berries in petridish. The same trials was conducted in the field, by infested them to healthy berries on coffee branches. Observation was done on the percentage of infected berries and number of CBB infected by B. bassiana inside the berries. The results showed that spores of B. bassiana could be picked up by CBB from disseminated containers, although it was very low (2.5%). B. bassiana was not effective in suppressing CBB infestation by auto-dissemination, therefore to improve the effectiveness of B. bassiana in controlling CBB, it was advised to re-spray at least 3 times in every cropping season, especially at the flying time of CBB around 2 P.M.

Abstract

Natural enemy is an important factor in management of cacao pests. One way to increase its diversity and abundance is through agroecosystem management techniques that support. The study was conducted for one year from February 2014 to February 2015 in Banjarsari Plantation and a cocoa farm of Kaliwining Experimental Station, Jember, which applied different cropping patterns and use of insecticides. The purpose of this research was to study the effect of cropping pattern and use of insecticide on diversity and abundance of predators, parasitoids, abundance and intensity of Helopeltis antonii attack. Observation of pests and natural enemies was done visually, using sweep net, yellow pan traps, malaise trap and pifall trap. Intensity of the attack used Pedigo & Buntin equations. Diversity index used Shannon Diversity Index (H’) and Simpson’s dominance index (C). Differences in predator abundance, parasitoid, air temperature, relative humidity, light intensity and rainfall used Wilcoxon test. Results of this study showed that monoculture and intensive use of synthetic insecticides caused lower diversity and abundance of predators and parasitoids, while the abundance and intensity of H. antonii attacks were higher compared with polyculture without insecticide. Banjarsari cocoa plantation that applied monoculture and intensive use of synthetic insecticides, had lower diversity and abundance predators and parasitoids compared with cocoa plantation in Kaliwining that applied polyculture planting without using insecticide. Dominant predators in Banjarsari and in Kaliwining cocoa plantations were Dolichoderus thoracicus and Araneus diadematus, while dominant parasitoid in Banjarsari and in Kaliwining cocoa plantations was Araneus diadematus.

Abstract

Coffee is not only the main export product in Timor Leste, but also a source of income for farmer household. The importance of coffee for Timor Leste community should be developed through market oriented farm management on coffee farming. The aim of this research was to analyze financial feasibility of Arabica coffee farming at farmer level; analyze sensitivity of coffee farming toward change in coffee productivity and price; and analyze correlation between productivity with socio-economic characteristics of farmers. This research was carried out at Poetete Village, Ermera Sub-district, Ermera District, Timor Leste. Primary and secondary data were collected in this research. Respondents were selected by stratified random sampling method. Financial feasibility study on coffee farming were analyzed by using Net Present Value (NPV), Internal Rate of Return (IRR) dan Net Benefit Cost Ratio (NBCR). Rank Spearman test was used to analyze the correlation between productivity with variable of production factors and socioeconomic characteristics of farmers. The results showed that Arabica coffee farming was financially feasible to be develop with NPV of USD 205,291,130; IRR of 17.449%; and Net B/C ratio of 2.911 at discount factor 10%. Arabica coffee farming at Poetete Village was classified less responsive toward productivity increasing at 10% and price decreasing at 10% with NPV of USD 37,367,151; IRR of 25.95%; and Net B/ C ratio of 3.862 at discount factor 1%. The correlation between productivity with land ownership (0.965), experience of farmers (0.613), age of farmers (0.663), farmers education level (0.748) and household size (0.791) were categorized as strong to very strong.
