Cocoa (Theobroma cacao L.) is an important crop in Indonesia, but many farmers still face problem in improving bean production. This research aimed to evaluate the effect of humic acid and biofertilizer applications on pod growth and yield of cocoa. The research was conducted at Kaliwining Plantation managed by Indonesian Coffee and Cocoa Research Institute at Jember District, East Java, Indonesia from June 2017 to February 2018. The experiment used mature tree of Sulawesi from one clone. Treatment used were humic acid at level of 0, 1000, 2000, 3000 and 4000 ppm in combination with biofertilizer at level of 0, 500, 1000, 1500 and 2000 ppm that were applied through soil and foliar respectively. Results of this experiment showed that there was an interaction between humic acid and biofertilizer on beans number per plant and photosynthesis rate. Plants treated with 1000 ppm humic acid produced the highest number of small cherelle. Biofertilizer applied at 1500 ppm increased cherelle number, healthy cherelle, number of young pods, number of harvested pods, bean weight per plant and bean yield. The combination of 1000 ppm humic acid and 1500 ppm biofertilizer increased bean production by 39.7%. The high bean production was in line with the high photosynthetic rate. Thus, humic acid and biofertilizer applications could be a way to increase cocoa bean production in this area.

Cocoa plant generally is classified as cross pollinated plant and self-incompatible plant, then there is indication the presence of pollen influence on cocoa bean quality. This study was aimed to determine the effect of pollen sources (xenia) on the colour and size characters of fresh cocoa beans (Theobroma cacao L.). This study was done on two stages. The first stage, a treatment of hand pollination of cocoa clones of DR 1, DR 2, DRC 16, KW 264 and ICCRI 03 was applied in this study. There were five treatments of hand pollination: DR 2 x DR 1, DRC 16 x DR 1, DRC 16 X KW 264, DR 1 x DR 2 and ICCRI 03 x DRC 16. Each treatment was repeated four times. Colour parameters of fresh cocoa beans were observed. The second stage consisted of nine hand pollination combinations: TSH 858 x Sulawesi 1, TSH 858 x ICCRI 03, TSH 858 x KW 264, TSH 858 x KW 570, TSH 858 x Sca 6, Sulawesi 1 x TSH 858, Sulawesi 1 x Sca 6, Sulawesi 1 x KW 570 and KW 516 x Sca 6. Each treatment was repeated three times. Size parameters of fresh cocoa pod and beans were observed. The result showed that hybridization using pollen source from bulk cocoa and DR 1 contributed dark colour to fineflavored cocoa. This colour contribution was showed by the increase in the dark fresh percentage of cocoa beans. On the other hand, hybridization using pollen source from fine-flavored cocoa contributed white and pale colour to bulk cocoa. This light colour contribution was showed by the decrease in the percentage of the dark fresh beans. Xenia effect occured on pod weight, pod length, pod girth, bean weight with pulp per pod and bean weight without pulp per pod which was shown by the hybridization with TSH 858 as female parent and weight bean without pulp per pod shown by the hybridization with THS 858 and Sulawesi 1 as female parent. Key word: Xenia, fresh beans colour, fresh beans size, Theobroma cacao L.

Cocoa bean husk is one of the product of cocoa which is only utilized as animal feed and has low economic value. Economic value of cocoa bean husks can be enhanced by extracting the husk using methanol into powder and applied to a process product namely cookies. Cookies are types of biscuit which are made from soft dough, high in fat and relatively crisp. The purpose of this study was to determine the amount of powder that was added and its impact to the cookies product. The analysis was done for sensory test, moisture content, fat content and protein content. The result showed that water content ranged from 2.39% - 4.85%. Fat content ranged from 7.57% - 8.64%, and ash content ranged from 0.73% - 2.02%. In the organoleptic test, the color and odor which were preferred by the panelists was treatment A0 (control) whereas the taste and texture was treatment A1 (addition of 5% powder).

A study was carried out to characterize the cocoa lipase from cocoa beans (Theobroma cacao, L.) of clone PBC 159. The optimum temperature of cocoa lipase was 30-40 °C and the pH optimum was 7.0-8.0. The moleculer weight of the lipase enzyme was in between 45-66 kDa. The results indicate that Km value for cocoa bean lipase was 2.63 mM, when trimyristin was used as a substrate. The incubation of cocoa bean lipase with triolein and tributyrin (as substrate) yielded Km of 11.24 and 35.71 mM, respectively. The Vmax value obtained from the incubation of the lipase with a wide range of substrates, including tributyrin, trimyristin and triolein, are expressed as µmole acid/min/mg protein for cocoa lipase. Vmax values decreased with the increase in the triacylglycerol chain-length, with Vmax values of 27.78, 13.16 and 11.63 µmole acid/min/mg protein when incubated with tributyrin, trimyristin and triolein, respectively. Inhibition of lipase occurred in the presence of diisopropyl flourophosphate, N-bromosuccinimide and 5,5-dithiobis-(-2-nitrobenzoic acid).   Keywords: characterization, lipase, cocoa beans

Cocoa bean is a rich source of polyphenols, which are the largest group secondary metabolite with natural antioxidant property. Polyphenols from cocoabeans was reported to possess health benefits. Fermentation, one step in cocoa processing is needed to improve the quality of cocoa in which the concentration of cocoa bean polyphenols might decrease significantly through oxidation and exudation. Cocoa polyphenols content among different cocoa clones mightalso vary. The aims of this study were to determine total polyphenols, total flavanoid, epicatechin, and catechin content in several cocoa clones, those wereSulawesi 1, Sulawesi 2, ICCRI 03, and KW 617. Until now, characterization of polyphenols from those clones has not been reported. The effect of five daysfermentation to those parameters was also studied. The results of the study showed that fermentation and type of clones significantly affected total of polyphenols, total of flavanoids, epicatechin, and catechin content of the cocoa, there is also an interaction between fermentation and type of clones. Unfermented of Sulawesi 1 had the highest total polyphenols of 96.94±5.83 mg/g, total flavanoids of 90.92±1.89 mg/g, epicatechin of 52.50±0.46 mg/g, and catechin of 1.99±0.02 mg/g content compared to other clones. Among five days fermented cocoa beans, Sulawesi 2 showed the highest total polyphenols and total flavanoids content, while ICCRI 03 had the highest epicatechin and catechin content than other clones. Thus, in can be concluded that although fermentation is required to improve the flavor quality of cocoa, it significantly reduced the content of bioactive compounds. This effect varied amongdifferent cocoa clones.

Biomass partitioning of cacao (Theobroma cacao L.) was studied in seven clones and five hybrids in a replicated experiment in Bahia, Brazil. Over an 18-month period, a 7-fold difference in dry bean yield was demonstrated between genotypes, ranging from the equivalent of 200 to 1389 kg·ha-1. During the same interval, the increase in trunk cross-sectional area ranged from 11.1 cm2 for clone EEG-29 to 27.6 cm2 for hybrid PA-150 × MA-15. Yield efficiency increment (the ratio of cumulative yield to the increase in trunk circumference), which indicated partitioning between the vegetative and reproductive components, ranged from 0.008 kg·cm-2 for clone CP-82 to 0.08 kg·cm-2 for clone EEG-29. An examination of biomass partitioning within the pod of the seven clones revealed that the beans accounted for between 32.0% (CP-82) and 44.5% (ICS-9) of the pod biomass. The study demonstrated the potential for yield improvement in cacao by selectively breeding for more efficient partitioning to the yield component.

Influence of inorganic fertilizer (NPK 15:15:15) and cacao (Theobroma cacao L.) leaf litter application rates on cowpea (Vigna unguiculata L.) performance in the tropics was studied for 24 months (January, 2017 – December, 2018) at Cocoa Research Institute of Nigeria (CRIN) Ibeku Sub-Station, Umuahia, Nigeria. Three 3 x 3 factorial experiments, each in a Randomized Complete Block Design (RCBD) with three replicates/blocks were used to study the responses of cowpea to three NPK 15:15:15 fertilizer rates 0 kg, 500 kg and 1000 kg ha-1 represented by (Factor F) F0, F1 and F2, respectively, and cocoa leaf litter rates 0 t, 10 t and 20 t ha-1 which were also represented by Lo, L1 and L2 (Factor L), respectively. The results obtained from the study show that the application of either 10 or 20 t ha-1 cocoa leaf litter alone or complementary application of either 10 or 20 t ha-1 cocoa leaf litter plus 500 or 1000 kg ha-1 NPK 15:15:15 fertilizer significantly increased the various cowpea growth and yield components than the fertilizer rates alone. The treatment without fertilizer and leaf litter, i.e. topsoil only (F0L0) gave significantly the least cowpea growth and yield components. The highest values were obtained with the application of 1000 kg ha-1 NPK 15:15:15 fertilizer with 20 t ha-1 cocoa leaf litter (F2L2). The cowpea crop performance in terms of growth, yield and yield components over the study periods, 2017 and 2018 were statistically similar. Therefore, the inclusion of leaf litter has greater potential for improving cowpea yield than when fertilizer was used alone. Leaves are potential sources of valuable nutrients providing a high quality of organic matter, which should be returned to the soil.
