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

Indonesia is the fourth largest coffee producer in the world, even though it is not the original plant. Efforts to increase coffee genetic diversity in Indonesia through the results of the introduction are also carried out to improve the quality and quantity of coffee in the international market. The aim is to obtain robusta coffee clones that are able to adapt in several agroclimates in Indonesia and have stable yield potential, so that they can be cultivated extensively. The analytical method is AMMI biplot with six clones are FRT04, FRT06, FRT07, FRT09, FRT23, FRT65, and six locations are Bangelan, Kalibendo, Kaliselogiri, Gumitir, Malangsari, Silosanen.Then the agroclimate is suitable for widespread cultivation. The results of the study based on observations made on the production of coffee plants, which are climate types, which are somewhat wet and are getting good production results in the locations of Bangelan, Kaliselogiri and Silosanen. FRT07and FRT09 clones is the best clone of production and able to adapt, has interaction between locations with clones tested annually.

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.

Abstract

Coffea arabica L. is a species of coffee that contribute for more than seventy percent of world coffee production. Various attempts have been made to obtain large quantities of planting material through propagation in vitro somatic embryogenesis technology. The objective of this experiment was to evaluate the effect of different plant growth regulators (PGRs) on callus induction (indirect somatic embryogenesis) in AS2K clone of Arabica coffee. Mother plants of Arabica coffee were established in coffee experimental field of Indonesian Coffee and Cocoa Research Institute at Andung Sari, Bondowoso, East Java, Indonesia (-7Ëš55'' ' S, 113Ëš41'' ' E) at an altitude of 1380,1 m dpl. Leaf explants were cultured on a half-strength Murashige and Skoog (MS) medium supplemented with various concentration (1.0, 2.0, 3.0 mg/L) of 2,4-D and (1.0, 2.0, 3.0 mg/L) thidiazuron in combination with 1.0 mg/L BAP. All the experiments were organized in completely random design (CDR) and repeated three times, each using minimum seven replicates (a total of 21 explants per treatment). The morphologycal and histological analysis of the different types of callus were observed. The percentage of callus formation was recorded every two weeks until eight weeks. The highest percentage of callus formation (almost 60%) was in medium containing 1 mg/L 2,4-D dan 1 mg/L BAP. Morphological and histological studies prove that the callus has a friable and embryogenic texture and begins to develop various stages of somatic embryo formation, starting with the globular, heart, torpedo and cotyledonary phases.

Abstract

Bondowoso Arabica coffee is a type of coffee that grows on the slopes of Mount Ijen-Raung. It has a high commercial value and distinctive taste. Coffee processing applications from roasting, grinding, packaging and brewing to storage will affect the quality of coffee. Caffeine is one of the compounds in coffee that contributes to bitterness and has certain pharmacological effects. This study aimed to determine the caffeine content of Bondowoso Arabica coffee harvested on August 2021 which was obtained from Sukosari Lor village with various roast profiles and types of packaging. In this study, Arabica coffee was roasted with light roast, medium roast and dark roast profiles. Then each treatment was mashed to obtain ground coffee. Ground coffee was put in a standing pouch made of polyethylene terephthalate (PET) with a thickness of 75 microns; polypropylene (PP) with a thickness of 100 microns; and polypropylene (PP) with a thickness of 120 microns and then stored for three months. During the storage of first and third months, caffeine levels were measured. Based on the results of the study, the caffeine content was increase along with higher roasting temperature. During the storage process, the caffeine content in ground coffee packaged using PP decreased the most.

Abstract

Vascular 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.
