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

Breeding for high yielding and good quality arabica coffee is the direction of the coffee breeding program in Indonesia. Hybridization becomes the important step to select promising genotypes from the genetic variability to achieve those goals. This research aimed to study heritability and combining ability of vegetative and yield characteristics of arabica coffee offspring. This research was conducted in randomized complete block design with three replications at Andungsari Experimental Station, East Java. The materials consisted of five parents of arabica coffee namely BP 542A(P1), P88(P2), S795(P3), HDT(P4), GEISHA(P5), and ten F1 hybrids as the offspring. The results showed that the narrow-sense heritability of leaf width was categorized as high. P3 and P5 varieties had the highest general combining ability (GCA) value for internode length, cluster number, and cherries number. These results indicated that both parental lines had potential as parents for the breeding program. The highest value of specific combining ability (SCA) for cherry size and leaf size was shown in crossing combination of P1×P3 and P2×P3. While, the crossing combination of P3×P4 showed the highest SCA value for cluster number, internode length, and cherries number per branch. From this crossing combination, high yielding promising lines can be obtained.

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

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%).
