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

To accelerate growth performance of Robusta coffee (Coffea canephora) seedling could be conducted through the application of exogenous plant hormone.Salicylic acid is one of plant hormones that widely applied to increase the plant growth for several plants, however, for coffee was still relative limited. This studywas aimed to determine the effect of salicylic acid on the growth of Robusta coffee seedlings which research was conducted at Indonesian Coffee and CocoaResearch Institute (ICCRI), Jember, East Java. This experiment was set using split plot design with three replications. The main plot was clones, which were BP 308and Sintaro clones. The seedlings were propagated from rooted cuttings. The subplot was the concentration of exogenous salicylic acid, that were control,0.6 mM, 1.2 mM, and 1.8 mM. The result demonstrated that BP 308 clone had higher rooting performance than Sintaro clone that shown by the higher rootvolume, root dry mass, and root/shoot ratio. In general, the application of salicylic acid could enhance the growth of Robusta coffee seedling. The application of 0.6 mMsalicylic acid increased plant growth of coffee seedlings. There was different response to concentration of application salicylic acid for both clones. The application of 0.6 mM salicylic acid could increase plant growth of BP 308, includeplant height, leaf area, stem dry mass, leaf dry mass, root/shoot ratio and total dry mass. Meanwhile, on Sintaro clone, application of 1.2 mM salicylic acid couldincrease leaf area, stem, leaf and total dry mass. The application of salicylic acid more than 1.2 mM led to detrimental effect of coffee seedlings.

Abstract

Coffee effervescent products are an innovation in coffee formulation. The compounds that play a role in effervescent are acids and bases. Type of organic acid give an impact on the effervescent characteristics. This study aimed to examine the effect of type of organic acid on physical, chemical, and sensory properties ofRobusta coffee effervescent tablets. This study used a completely randomized design with three acids in the formulation, namely citric acid, tartaric acid, and malic acid. Samples were analyzed in three replications. Making effervescent tablets was done by compression technique in a mixture of all ingredients according tothe formula. The results showed that different acid had a significant effect on physical and chemical parameters. Malic acid caused a faster effervescent time than citric acid and tartaric acid. Malic acid and tartaric acid tended to lower the pH slightly than citric acid. Malic acid and citric acid tended to produce hardertablets than tartaric acid. However, tartaric acid slightly increased tablets’ brightness (L*) compared to malic acid and citric acid. Tartaric acid and malic acid tended to reduce moisture compared to citric acid. The IC50 value of effervescent with malic acid and tartaric acid was lower than that of citric acid. However, therewas a slight decrease in total phenol in both. Meanwhile, the sensory profiles of tablets and effervescent drinks did not differ due to different acids. The recommended formula was that the effervescent using malic acid had an effervescent time of 166 seconds, hardness 321 N, moisture 8%, IC50 5.5 mg mL-1, total phenol4.2 mg gallic acid equivalent (GAE) g-1, and a drink profile that has the best color, aroma, taste, and runs time

Abstract

The genetic purity of a plant indicates the similarity properties between seedlings in the field and the description of the plant in the database. Identifying plant purity through a morphological approach has several drawbacks, including time efficiency and environmental factors, and the diversity is limited and inconsistent. This condition encourages the development of detection methods using DNA molecular markers. Plant identification through fingerprinting or the use of molecular markers has not been widely carried out on a commercial scale, considering the investment costs for this analysis are still quite expensive. Another method used for plant identification through DNA Barcoding by comparing variations between DNA sequences. The primers used to identify barcodes on cocoa were derived from the chloroplast genome, including rbcL and matK. This research aims to see the consistency of the rbcL primer when applied to other cocoa clones, and the analysis of the polymorphic diversity of each cocoa clone using DNA fingerprinting RAPD. This method will be tested on clones of Sulawesi 1, Sulawesi 2, ICCRI 03, and ICCRI 09, which were propagated by SE and mother plants in the field using cocoa leaf samples. The stages include DNA extraction, sequencing, and analysis of the sequencing results. The results of seedlings uniformity analysis using DNA barcoding on cocoa plants produced from in vitro propagation showed that the multiplied seeds did not show any difference in sequence with the parent plant (DR2, Sulawesi 1, Sulawesi 2, and ICCRI 09). The analysis of the diversity of cocoa clones DR 2, MCC 2, Sulawesi 1, Sulawesi 2, and ICCRI 09 through DNA Fingerprinting RAPD showed that the OPA 15 primer produced a more apparent polymorphic band than the other three primers (OPP 08, OPW 11, and M 29).

Abstract

Organization of plant aerial parts and root distribution, environmental conditions such as light, temperature, humidity and agronomic practices (grafting and pruning) influences the final architecture of the plant. Most of cocoa plantations in Colombia belong to the plagiotropic type that emit branches and suckers in a disorderly way, which leads to an unbalanced development, this makes it difficult to manage. To search for cocoa plants with better architecture, we evaluated the effect of the type of the bud (orthotropic and plagiotropic), the grafting techniques (approximation and patch grafting) and pruning (structural and conventional) on ICS 95 and CCN 51 clones. The monitoring was carried out at an open greenhouse and field. Plants obtained from orthotropic buds and approximation grafting had lower bifurcation angles, 42% more leaves and 50% more branches. The structural pruning had a positive influence on the architectural variables, which presenteda higher conversion (8.68%) of fresh weight of cocoa pod into dry weight of cocoa beans, meanwhile CCN 51 trees showed a higher conversion (9.76%) compared to ICS 95 (7.34%). CCN 51 had the highest bean index (1.30) and the lowest pod index (22.0). This study demonstrated that structural pruning improved bean indexand pod index. We concluded that for CCN 51 by approximation grafting technique is a good alternative for a tropical dry forest, as its production between 1995 and 2277 kg of dry cocoa beans ha-1 year-1.

Abstract

Breeding for high yielding, pest and disease resistance, and good quality Arabica coffee is the direction of the coffee breeding program in Indonesia. Threeway cross-breeding method becomes the alternative method to improve plant genetics to achieve those goals. This research was aimed to evaluate the agronomic performance and grouping of Arabica coffee genotypes from three-way cross progeny. This study was conducted in Andungsari Experimental Station, Bondowoso, East Java from July until September 2021. A randomized complete block design with three replications was used as an experimental design. It consisted of eight Arabica genotypes resulting from three-way cross method and one check variety (Andungsari 1) as treatments. The tested genotypes were resulted from crossing parents i.e. S 1934, AB 3, RC, YC, S 795, and Catimor that was planted in 1997. The results of the agronomic performance evaluation showed that TWC (Tree Way Cross) 2 ((S 1934/AB 3 x AB 3) x AB 3) and TWC 3 (RC/S 795 x Catimor) had good agronomic characteristics i.e. weight of 100 cherries and cherry weight per tree. While grouping using heatmap clustering method showed that there were three groups of genotypes. One of the groups which consisted of TWC 1 ((S 1934/AB 3 x AB 3) x S 1934), TWC 2 ((S 1934/AB 3 x AB 3) x AB 3), and TWC 5 (S 1934/YC x S 1934) were categorized as moderate yield group.

Abstract

The fermentation of cocoa beans is a key step in increasing their quality. Temperature and pH have an impact on the fermentation process' performance. Until, temperature and pH measurements in the cocoa bean fermentation process have been done with a thermometer and a pH meter, and have been heavily impacted by experience and knowledge. The goal of this research is to create a temperature and pH monitoring system for the fermentation of cocoa beans using an android platform. The sensor must be able to measure temperature and pH during the fermentation process, and the sensor reading data must be displayed on the android display, according to the system design criteria. A temperature sensor, pH sensor, microcontroller, TP-Link or WiFi modem, ThingSpeak (data storage), and Smartphone make up the system's hardware. Arduino CC software version 1.8.14 was used to create the software. The system hardware was made up of numerous components, including the NodeMCU ESP32 microcontroller, SKU SEN0161 pH sensor, DS18B20 temperature sensor, 4.2k resistor, jumper cable, and 5 volt charger adaptor, according to the results. A plastic container houses the electronic system circuit. The monitoring system can read the temperature and pH during the fermentation process, which lasts 112 hours or 6 days, according to the performance test findings. During fermentation, the temperature of cocoa beans ranged from 27.19 °C to 41.75 °C, with the pH fluctuating between 2.50 and 7.10.

Abstract

Leaf morphological traits and internode length significantly affect the adapt-ability and production of coffee plants, respectively. Therefore, genetic studies of these two characters can support the effectiveness of Robusta coffee breeding program for obtaining superior planting materials. This study aimed to determine the diversity and frequency distribution of F1 generation on internode length and leaf size of Robusta coffee crosses. The study involved six groups of F1 progeny and their reciprocals (F1R) resulted from a cross of three parents, namely BP 961, Q 121, and BP 409. Each cross combination was planted with 41–49 progenies singly side by side in Kaliwining Experimental Station, Jember, Indonesia. The observed traits were internode length and leaf size. Analysis results of progeny variation distribution showed that most of the F1 and F1R progenies from intraspecific Robusta crosses had shorter branches than both parents in all combinations of crosses, even in BP 961 × BP 409 crosses. In addition, all F1 and F1R progenies had shorter internodes than both parents. More than 50% of the progeny of Q 121 × BP 409 and BP 961 × BP 409 crosses showed leaf length trait between parents. This indicates the absence of dominance of one parent in the progeny. Less than 20.9% of the progeny had a narrower leaf size than Q 121 parent. Most of the F1 and F1R crosses had a leaf width between both parents. The leaf length and leaf width traits were incomplete dominance or recessive, while the internodelength was overdominant.

Abstract

Cocoa and gold are significant contributors to the gross dormestic product of Ghana which makes both commodities key parts of the Ghanaian economy. Unfortunately, in Ghana, most cocoa-growing communities are the hub of illegal small-scale mining commonly known as galamsey. It is alleged that cocoa farmerssell their farmlands for galamsey; however, given that cocoa farming is the primary source of income for many households in rural Ghana. This research aimed at investigating the motivations for galamsey and how the practice impacts cocoa farming and the environment as well as farmer livelihood. The study was undertakenin Amansie West District in the Ashanti Region of Ghana where both cocoa farming and illegal mining operations coexist. The data for the study was collected using structured questionnaires. Cocoa farmers were purposively selected as respondents in two cocoa-growing communities. Data were obtained from 90 purposively sampled respondents through snowballing. Data collected were analyzed with Statistical Package for Social Scientist software. The results revealed that cocoa farmers face challenges due to galamsey such as; labour shortages, water pollution, competition for land amongst others. Also, cocoa farms, especially those downslope, get flooded whenever it rains as a result of uncovered galamsey pits near farms and cause black pod disease, early dropping of immature pods and stunted growth which ultimately reduce the output of cocoa farms. Farmers revealed that this affected their source of income adversely since the majority of them mainly depend on cocoa farming for their livelihood. They also reported a loss of green space and land degradation as some environmental hazards posed by galamsey. Information gathered from tenant farmers revealed that it is mostly landowners who give out their lands for galamsey. The major reasons that encourage galamsey were identified as higher short-term income, financial problems (40%) due to unemployment, and poor cocoa yield (26%).

Abstract

The presence of free radicals and oxidants in our body is either produced by our body through normal cell metabolisms or from environment surrounding us such as radiation, medication, pollutants or others. The free radicals and oxidants can be harmful to our body when their accumulation posing oxidative stress in the body. Cocoa beans are rich in polyphenols, which are functioning as antioxidant. However, each antioxidant has difference response towards either free radicals or other oxidants. The purpose of this research was to study the ability of cocoa fresh beans aqueous extract functions as antioxidant between its ability to reduce ferric to ferrous and number of free radicals removed from organic chemical compound of 2,2-diphenyl-1-picrylhydrazyl (DPPH). A series concentration of cocoa fresh beans aqueous were prepared. Its ability as ferric reducer was determined based on ferric reducing antioxidant power (FRAP) assays and its ability as free radicals scavenger was determined using DPPH assays. This study revealed that freeze dried cocoa fresh beans aqueous extract of 50 ppm was able to reduce 3.2 x 10 15 of ferric molecules to ferrous. Concentration below 20 ppm generally was not able to reduce Fe(III) to Fe(II). Whereas, at concentration of 45 ppm freeze dried cocoa fresh beans aqueous extract was estimated able to remove 1.4 x 10 17 organic nitrogen free radicals from DPPH assay. This study suggests that freeze dried cocoa fresh beans aqueous extract has better performance in quenching free radicals compared to reducing ferric into ferrous.

Abstract

The study investigated COVID-19 pandemic awareness and coping strategies of cocoa farmers in Ondo State of Southwestern Nigeria. Random sampling technique was used to select cocoa farmers in the study area. A total of fifty cocoa farmers (respondents) were purposively selected from Ile-Oluji/Oke-Igbo local government area of the state. Information was collected from the selected farmers with the aid of well-structured questionnaires and the data retrieved from forty-six cocoa farmers collected were analysed with descriptive statistics and chi-square analysis. The result of the analysis showed that 76.1% of the farmers are above the age of 41 years, 78.3% are males while 76.1% are married. Similarly, 78.3% of the cocoa farmers have 4-6 children in the household, 26.1% had secondary education, 43.5% have 16 to 20 years farming experience while 73.9% lived in condominiums or housing units where residents are herded together thereby predisposing them to the risk of the contagion. Most of the respondents (95.7%) had low income or sales during covid-19 pandemic, 78.3% ate food three times before covid-19 while 15.2% ate three times during the pandemic. 89.1% did not have enough food at home during the lockdown and 95.6% did not have enough money to buy food during the pandemic. Majority of the respondents (96%) were aware of the occurrence of COVID-19, 69.6% of the respondents coped by relying on less expensive food during the lockdown, 56.5% reduced their food consumption due to income loss, 63% reduced the number of meals eaten daily while 67.4% reduced the portion or size of meal daily during COVID-19. The chi-square test also showed that a significant relationship exists between farmers’ awareness and coping strategies to covid-19 as well as the quality and type of food they consumed.
