Heritability and Combining Ability of Some Vegetative and Yield Characteristics of Promising Arabica Coffee Varieties in Indonesia
Full text linkBreeding 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
Temperature and pH Monitoring System Design in the Fermentation of Cocoa Beans Based on Android
Full text linkThe 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.

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
Assessing the Impact of Illegal Small-Scale Mining (Galamsey) on Cocoa Farming and Farmer Livelihood: A Case Study in the Amansie West District of Ghana
Full text linkCocoa 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%). 
Covid-19 pandemic awareness and coping strategies of cocoa farmers in Ondo State of Nigeria
Full text linkThe 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
Flush characteristics of several cocoa genotypes different in resistant to vascular streak dieback
Full text linkVascular streak dieback (VSD) is one of the main diseases on cocoa that can cause a decrease in production and even death on susceptible plants. The use of selection criteria is very important in the selection process at the seedling phase, young plants and even mature plants in order to support the breeding process of resistant varieties. The aim of the study was to determine the characteristics of flush including flush color, stomata characters and duration of flush color change to green or towards mature leaves as one of the selection indicators for VSD resistance in cocoa. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, Indonesia. Study of flush color and stomata characters was conducted using a randomized complete block design consisting of four cocoa genotypes with different levels of resistance, classified as resistant to VSD disease (Sulawesi 1, PNT 16) and as susceptible (BCL and BL 50). Each clone was repeated three times and each replication consisted of three plant samples. Flush color duration study was carried out on six cocoa genotypes as treatments, three genotypes with resistant to VSD (PNT 16, Scavina 12, Sulawesi 1) and three genotypes as susceptible to VSD (BL 50, BCL, Criollo 22). Each treatment was repeated three times and each replication consisted of three plant samples. The results showed that the resistant genotypes showed a tendency to have lower chlorophyll and anthocyanin content than the susceptible ones. The stomata character in the resistant genotypes was not different than the susceptible ones, however, the resistant genotype showed that the stomata density at flush tended to be lower. The duration of flush color change to mature leaves (green) in resistant genotypes was significantly faster than susceptible genotypes
Physical, Chemical, and Sensory Properties of Robusta Coffee Effervescent Tablets Formulated in Various Organic Acids
Full text linkCoffee 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 tim
Cocoa fresh beans aqueous extract as free radical quencher and ferric reducer.
Full text linkThe 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
