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

Indonesian cocoa is leading commodity that is able to export to other countries such as Malaysia. Exporting countries compete with each other for the Malaysian market, even though world demand for cocoa beans continues to increase. The study aims to identify the competitive position, elasticity, and market structure of Indonesian cocoa beans and exporting countries in the Malaysian market. The research data source is secondary from ITC Trade Map, from January 2017 to December 2023. The variables used are the value and quantity of cocoa bean exports from 8 exporting countries in Malaysia. The analytical used are Almost Ideal Demand System (AIDS) approach to determine level of competition and Herfindahl-Hirschman Index (HHI) and Concentration Ratio (CR) analyses to see market structure. The results of the HHI show that cocoa bean exports in the Malaysian have a high degree of market concentration, with CR4 reaching 71% and CR8 reaching 91%. The AIDS results that expenditure elasticity is negative, indicating that Indonesian cocoa beans are inferior good. The elasticity itself is negative, indicating that Indonesian cocoa beans are inelastic. Cross price elasticity, Indonesia has substitution relationship with Ecuador, Ghana, and Cameroon, and complementary relationship with Côte d'Ivoire, Nigeria, Papua NG, and Uganda.

Abstract

In response to the outbreak of Coffee Wilt Disease (CWD) which wiped out almost 50% of Robusta coffee in Uganda, the National Coffee Research Institute (NaCORI) released 10 varieties (KR1-10) which are resistant to the disease. These varieties are being multiplied by stem cuttings for commercialization, although some of them present challenges in rooting. Research shows that rooting ability of stem cuttings is a function of the variety, their morphological status and rooting hormone used, among other factors. We therefore conducted an on-station study to determine the effect of morphological age of the stem cuttings and Indole-3-Butyric Acid (IBA) rooting hormone concentration on the rooting ability of varieties, KR1, KR3 and KR4. A factorial experiment with three stem segments with differing morphological age (softwood, semi-hardwood and hardwood) and five IBA concentrations (0, 1, 2, 4, 7 and 10g/l) was set up for each variety in a completely randomized design and replicated five times. Results showed that the number of roots produced by stem cuttings varied significantly (p?0.05) across varieties and IBA concentration level but not the morphological age of the cuttings. The highest number of roots was recorded on variety KR4, (35.3), 2 g/l of IBA (31.5) and softwood cuttings (29.1). Furthermore, the number of roots produced by stem cuttings varied significantly (P<0.00001) across combinations of factors. The highest number of roots was recorded on softwood treated with 10 g/l of IBA rooting hormone for KR1, hardwood cuttings treated with 2 g/l of IBA for KR3 and softwood cuttings treated with 2 g/l of IBA for KR4. Our findings provide a guide on variety-specific approaches for enhancing rooting ability of stem cuttings of these CWD-r Robusta coffee varieties. We therefore recommend that similar studies be conducted on variety, KR8 which also has been recently reported for challenges of rooting of its stem cuttings.
