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

Sustainable waste management and the preservation of soil health represent critical challenges in intensive coffee and cocoa plantation. Composting offers an effective approach for sustainable waste management by enhancing soil health, while arbuscular mycorrhizal fungi (AMF) optimize nutrient uptake (NU) efficiencyin coffee plants. This research aimed to investigate the effect of cocoa pod huskbased compost inoculated with AMF on soil chemical properties and NU in coffee plants. This research employed a completely randomized design with two factors. Factor I consisted of three compost doses: K0 (no compost), K1 (15% compost,w/w), and K2 (30% compost, w/w). Factor II comprised three levels of AMF: F0 (no AMF), F1 (15 g polybag-1 ), and F2 (30 g polybag -1 ). Compost application significantly enhanced soil nutrient levels of N, P, K, C-organic, and CEC, as well as improved the uptake of N, P, and K by coffee plants. Similarly, AMF significantly increased soil P levels and P uptake by coffee plants. The combined application of compost and AMF further contributed to an increase in soil P availability. The K1F1 treatment (15% compost and 15 g AMF polybag -1 ) was the most effective in optimizing nutrient turnover, as indicated by the highest uptake of N (33.48 g plant -1) and P (1.37 g plant -1), which contributed to enhance plant performance. According to nutrient availability classification, this treatment supplied sufficient soil N (0.36%) and soil organic C (SOC) (2.54%). However, excessive N and SOC induces antagonistic interactions, compromising the efficient uptake of P and K, while deficiencies constrain overall nutrient acquisition.

Abstract

Primary commodity price trends frequently exhibit co-movement patterns, demonstrating similar fluctuations. The surge in substitute commodity prices, such as Arabica coffee and cocoa, in both Indonesian and global markets has positively impacted the increasing price of Indonesian Robusta coffee. This study explored the factors driving the surge in Indonesian Robusta coffee price, particularly the co-movement of substitute commodity prices and exchange rates, and how these elements influence Indonesian Robusta coffee price behavior. Utilizing time series data from January 1, 2019, to December 31, 2024, the research applied the ARDL-ECM approach to estimate the cointegration relationships among the variables. The results revealed that lagged Indonesian Robusta prices, world Robusta price, Indonesian Arabica price, lagged world Arabica price, London cocoa price, and the Rupiah exchange rate significantly affected Indonesian Robusta price at the 1%, 5%, and 10% significance level, both in the long and short run. Furthermore, the study identified a bidirectional causality between Indonesian Robusta coffee price and three independent variables: New York, London, and cocoa indicator prices. In contrast, Arabica prices, rubber prices, and exchange rates showed no causality with the Indonesian Robusta coffee price. The analysis also indicated that price co-movement was only reflected among related commodities, while no such relationship was found for unrelated commodities. The upward trend in world Robusta price, Indonesian Arabica price, world Arabica price, and world cocoa prices can be interpreted as indicators of a flourishing agricultural primary commodity market, which may subsequently drive up Robusta coffee prices in the domestic market.

Abstract

Agroforestry systems have garnered significant attention for their potential in enhancing soil organic carbon (SOC) stocks, particularly in coffee plantations. The different shading conditions not only diversifies production but also plays a crucial role in soil health and carbon sequestration. The study aimed to investigate the SOC stocks under various coffee-based agroforestry systems. Four different shading conditions have been examined, namely: A (unshaded), B (Leucaena leucocephala shade), C (Pinus sp. shade), and D (complex agroforestry). The results were analyzed descriptively by comparing the influence of varying shading conditions in enhancing SOC stocks. The results indicated that complex agroforestry had the highest SOC (1.33%), followed by L. leucocephala shade (1.20%), unshaded (1.02%), and Pinus sp. shade (0.96%). In the complexagroforestry system, the diversification of plant species increases soil organic matter (SOM) and root biomass, thus improve SOC. Meanwhile, the Pinus sp. shade exhibited the lowest SOC due to the lower quality of its resistant litter. The complex agroforestry also recorded the highest SOC stocks (42.7 t C ha -1), followed by unshaded (39.9 t C ha -1), L. leucocephala shade (38.3 t C ha -1), and Pinus sp. shade (30.5 t C ha-1). The SOC stocks in the unshaded system exceeded those under L. leucocephala shade due to higher bulk density resulting from the absence of complex root systems. Moreover, the complex agroforestry exhibited elevated levels of soil N, P, K, and CEC. These findings implied that complex agroforestry system represents a multifaceted approach to enhance SOC stocks and soil health in coffee plantation.

Abstract

Cocoa (Theobroma cacao L) is a plant that is widely cultivated by the Indonesian people. Many cocoa farmers experience crop failure due to pests and diseases. One effort that can be made to reduce this problem is to create high-quality cocoa seeds that are able to survive when attacked by pests and diseases. This study aims to investigate the effect of adding nutrients in the form of biosaka and Trichoderma sp. to cocoa seed soaking water on radicle length. The biosaka treatment used three different formulas: A: control, B: formula 1 (a mixture of weeds and water shoots in a 1:1 ratio), B: formula 2 (a mixture of weeds and water shoots in a 2:1 ratio), and C: formula 3 (a mixture of weeds and water shoots in a 1:2 ratio). Each biosaka solution was mixed with Trichoderma sp. at a dilution of 10-1, and the treatment was repeated three times, with three cocoa seeds in each replicate. The results obtained indicate that the best biosaka formula for cocoa seed radicle length, spore count, and spore density of Trichoderma sp. is the biosaka with a weed and water sprout ratio of 2:1 mixed with Trichoderma sp. at a dilution of 10 L .

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.
