Abstract

Study was conducted on coco peat as a low emission pellet form biomass fuel alternative to produce synthetic gas (syngas) through gasification process in use for other processes. Coco peat was first screened and formulated with other materials such as coco peat, starch, and waste cooking oil. These materials were mixed and pelletized using a pelletizer to form coco peat pellet. It was burned on an updraft gasifier to produce synthetic gas (syngas) and then streamed to a stove through a pipe. The syngas was then split and burned and the heat generated was used for boiling water and for drying agricultural products. Air quality around the stove (emission test) was measured and analyzed when gasification took place. The best results of coco peat pellet were made from 85% of coco peat waste, 5% starch (binder), and 10% of waste cooking oil with stronger texture and shiny surface. The experimental gasification using updraft gasifier exhibited better result when half of the volume of gasifier was filled with 5 kg pellet and the syngas produced can be used for 3.5 hours drying and boiling. Air quality surrounding the stove was tested during gasification process. It was done based on the Indonesian Environmental Regulation issued by Indonesian the Ministry of Environment on Standards (KEP-13/MENLH/3/1995 dated March 7th, 1995) regarding standard air quality from static matter and covers NH3, Cl2, HCl, HF, NO2, particles, SO2 and H2S parameters. The result of measurements indicated that all parameters meet the quality standards) including CO and CO2 at 0.0001 mg/kg.

Abstract

Chocolate is a well-known dessert all over the world. The original chocolate is made from cocoa products: cocoa bean and cocoa butter. Research and Development on low-fat chocolate process were conducted for value addition of coconut oil and Thai fruit. This chocolate processing study composed of (1) coconut oil fractionation, (2) chocolate formulation and (3) shelf-life storage determination. Accordingly, fatty acids composition of the blend of coconut fat and palm oil shortening were determined. It was found that the said product composed of Caproic acid 0.47±0.12%, Caprylic acid 5.65±0.31%, Capric acid 5.14±0.14%, Lauric acid 42.56±0.28%, Myristic acid 16.31±0.18%, Stearic acid 14.55±0.13%, Oleic acid 9.26±0.17%, and Linoleic acid 2.16±0.35%. The saturated fatty acids and unsaturated fatty acids found in this product were 88.57±0.14% and with 11.42±0.81%, respectively. The range of melting point is 260C-330C and oxidative stability is 14.2 to 16.7 hours. The chocolate formula of pale and dark chocolate 1kg composed of coconut fat, palm oil shortening, and lecithin as emulsifier in same amounts such as 250g, 100g, and 0.5g. However, icing sugar and defatted cocoa powder are in different amounts; the icing sugar in pale chocolate and dark chocolate is 350g and 450g while the defatted cocoa powder in pale chocolate and dark chocolate is 200g and 300 g, respectively. These chocolate products have physical properties similar to the chocolate products produced from cocoa butter. The shelf life of these products is 3 months.

Abstract

Pati Dwarf Kopyor coconut originated from Pati, Central Java is one of the Kopyor coconut populations from Indonesia. Three varieties of Pati Dwarf Kopyor coconut, namely: Kopyor Green Dwarf, Kopyor Brown Dwarf and Kopyor Yellow Dwarf out of six potential varieties have been officially released as local superior varieties by the Minister of Agriculture, Republic of Indonesia at the end of 2010. The objectives of this research were to evaluate the stability of Kopyor fruit production among provenances of Pati Dwarf Kopyor coconuts. Evaluations were conducted especially for the three recently released varieties of Kopyor coconuts. Observations were carried out in 2011 and the collected data were then compared with Kopyor fruit production data collected in 2009 -2010. In three different locations, representatives of 10 Kopyor coconut provenances for each Kopyor variety were observed; therefore, a total of 90 trees were evaluated in this experiment. Observations were conducted for number of total bunches per palm, number of total fruits/per bunch, and the number of harvested Kopyor coconut fruits/per bunch. Three bunches were selected for each of the evaluated provenance. Results of the observation indicated that the observed yield and yield parameters of three Pati Dwarf Kopyor coconut varieties fluctuated by the year of observations. However, in general the observed yield and yield parameters among three varieties were similar. The average number of total bunches observed among three varieties evaluated ranged from 9.6-12.1 bunches per palm; the average number of fruits/per bunch ranged from 5.3-12.4; and the average number of harvested Kopyor fruits/per bunch ranged from 2.0-3.8. The estimated number of total fruits/palm/year among the three varieties ranged from 53.8-128.1 and the percentage of Kopyor fruit production observed among the three varieties evaluated ranged from 24.8-38.9 %. The estimated number of total harvested Kopyor fruits/palm/year ranged from 20.5-39.2, respectively. Rainfall pattern might affect directly or indirectly toward yield and yield components of three Pati Dwarf Kopyor coconut varieties.

Abstract

The pheromone mass trapping programme for coconut black-headed caterpillar (BHC), Opisinaarenosella Walker under development at the south eastern dry zone of Karnataka calls for a proper monitoring system. Experiments conducted at Bidadi, Nelamangala, Nittur and Thyamagondlu near Bangalore, peninsular India to establish the emergence pattern of BHC indicated that nearly six emergence peaks of moths were recorded in 18 months. The duration of emergence and non-emergence periods of moths was approximately 41 days (SD= ±3.93) and 48 days (SD= ±4.35) respectively. The maximum number of days of moth and non-moth emergence was recorded during March, April and May. The studies on emergence pattern throughout the generation indicated that the moth emergence followed a normal curve. The moth emergence pattern of BHC in four coconut gardens at Nelamangala, Thyamagondlu, Nittur and Bidadi indicated the occurrence of spatially segregated moth emergence. The present studies provided thoughtful information on flight pattern of BHC in each generation and also throughout the year. Such basic results are helpful in designing pheromone based pest control strategies.

Abstract

The Tetrastichus sp. was identified as a pupal parasitoid indigenous to the Philippines. The total development period of Tetrastichus sp. from egg to adult was 16 days under laboratory conditions. The average incubation, larval and pupal periods were 3.5, 4.8, and 7.4 days, respectively. The average adult longevity was 5.5 (male) and 6.4 (female). Upon emergence of an adult wasp from the host pupa, mating took place shortly and the female look for suitable host pupa of Brontispa longissima for oviposition. Tetrastichus sp. is an endogregarious parasitoid. From one parasitized pupa of Brontispa longissima, around 6 - 66 individual wasps emerged with a mean of 22.4 while parasitized pupae collected from the field yielded 4 - 21 individuals with a mean of 12.7. Majority of the wasps emerged in the morning (70%) while 30% emerged in the afternoon. Sex ratio of male and female was 1:5.4 in laboratory condition while 1:3.7 under field condition with females outnumbered the males. Tetrastichus sp. was observed in some cases to reproduce parthenogenetically. Longevity of Tetrastichus sp. can be enhanced to a mean of 7.3 and 6.0 days by feeding on sugar and honey, respectively while water and coconut pollen resulted in longevity of 3.3 and 2.4 days, respectively. Adults without food lived only one day. Parasitism efficiency ratio of 10 parasitoids: 10 host pupae resulted in 90% parasitism. One to two day old pupa of B. longissima was preferred by Tetrastichus sp. for oviposition with a mean of 86.7% parasitism. Percent pupal parasitism in the field ranged 25.7 - 42.3% with an average of 27.6% in selected areas in Mindanao. Tetrastichus sp. was found to effectively control B. longissima under field condition. The study indicated that Tetrastichus sp. is an effective control agent of B. longissima and could be used in the field to prevent economic damage of the palms by the pest.

Abstract

Curd coconut (CC) is a rare abnormality in the meat of the coconut which is thicker than normal and is fluffy and soft like curd. Being more delicious than normal coconut, CC is favored by people who eat it as dessert. In ten countries where CC occurs, its occurrence is at a very low frequency of about 0.15%. CC is produced on a normal-looking palm which bears mostly normal fruits except for a very few CC fruits. Such fruit does not germinate, thus cannot be used to propagate the character. The experienced growers germinate normal-looking fruits obtained from the CC-bearing palm, which may or may not yield CC fruits after 8 years of planting. A controlled self-pollination of the CC-bearing palm yield a 3:1 ratio of normal: CC fruits, indicating the mother palm is a heterozygote (Kk) for the CC character, which is recessive (kk). The CC endosperm (kkk) cannot produce the enzyme galacto-mannanse to digest galactomannan to produce mannan. Thus, it contains galacto-mannanase that is viscous, but is not digested as food of the CC embryo. Consequently, it eventually dies. Galactomannan is responsible for the fluffy texture of the CC. CC embryo can be cultured in aseptic condition. Upon growing this cultured embryo to fruit-bearing stage, CC fruits are produced 100% if self pollinated. A hybridization scheme has been conducted by the Thailand Horticultural Research Institute. Pollen sources were from embryo-cultured palms while maternal parents were found dwarf cultivars, namely ‘Nam Hom’, ‘Thung Khlet’, Malayan Yellow Dwarf’, and ‘Malayan Red Dwarf’. The F1 hybrids were mostly semi-dwarf in stature (that is selfing in nature); they all produced 25% CC fruits as expected. The most interesting cross was that with ‘Nam Hom’, in which 56% have aromatic water. It is postulated that if a backcross is made between semi-dwarf F1 with the CC homozygous (kk) embryo-cultured palms, the resultant offspring would yield 50% CC fruits which doubled that of the F2 which yield only 25% CC fruits. Not only CC fruits are delicious, they are also nutritious with higher amount of saturated and less unsaturated fatty acid than normal fruits. CC is always high on demand because people love to eat CC as dessert, even at the price ten times as much as ordinary coconut. CC growers earn 2.5 times as much compared to ordinary palms if they grow F1 hybrids, but will double that amount if they make backcross by using pollens from homozygous embryo-cultured palms (kk).
