Abstract

Aceh province is one of major coconut producing areas in Indonesia. In 2013 coconut areas in Aceh province was 107,654 ha in which total production of copra was equivalent to 63,743 tons. The entire coconut area in Aceh belong to smallholders. The coconut production in this area began to decrease in 2005 by an average of 9 percent per year, which was mainly caused by the tsunami. This had resulted in damage to many crops. Efforts to increase production and productivity of coconut plantation in Aceh needed rejuvenation of the old or unproductive coconut palms with the use of seeds of improved quality. Based on the results of the research conducted during 2014-2016, it is known that the origin of the Lampanah tall is passed from generation to generation and is a native of coconut in Aceh Besar Regent, Aceh Province. The morphology of Lampanah tall coconut comprising of the crown of leaves, stems, flowers and fruits in general is quite uniform. Of the data on the 23 quantitative characters, all have a value of coefficient of variance below 20%, except the character of 11 leaf scars obtained 23.29%. In the case of polar girth, Lampanah tall coconut is generally greater than the equatorial girth, fruit shape classified as round, egg-shaped and elliptic. The seednut of Lampanah tall generally round shape. The Lampanah tall coconut has the number of bunches at 13.35/palm and the number of fruit at 9.25 fruits/bunch or an average of 138 fruits/palm/ year. Fresh coconut meat weight is 449 g/nut or approximately 224 g copra/nut and the potential for copra production was 30.97 kg/palm/year or 3.80 tons of copra/ha/year. The fat content of Lampanah tall coconut was 66.40%, the water content of copra approximately 3.42% and protein at approximately 6.81%. Total saturated fatty acids was at 94.27%, medium chain saturated fatty acids at 67.21% and lauric acid content at 46.50%. The seed source of Lampanah tall coconut has been a selection of as much as 72 Selected Mother Palms (MAS) from a total of 407 palms of the High Yielding Block. The selected population is characterised with traits like copra yield more than 2.0 ton/ha/year, free from attack pests and diseases, number of bunch more than 12 per year, total nuts more than 7/bunch and weight of meat more than 400 g/nut. The MAS of Lampanah tall whole coconut has been marked using GPS. The Aceh government will build a minimum of 5 ha Coconut tall Seed Gardens on government land, as the development of source of Lampanah tall seednuts. Based on the above results, it can be concluded that the Lampanah tall coconut with plenty of nuts, at an average of 138 nuts per palm could be released as one of the national high yielding coconut.

Abstract

The purpose of this research was to study processing of coconut oil which focused on evaluation of the quality of oil by using fruit of several Dwarf coconut as raw materials. The varieties used were Salak Green Dwarf (SGD), Raja Brown Dwarf (RBD) and Bali Yellow Dwarf (BYD). The oil was extracted through the wet process by heating technique. The coconut oil volume was measured and evaluated for its fatty acids profile, free fatty acid contents, moisture content, color, smell and taste. The by-products such as coconut residue and blondo were measured, too. The results showed that processing of oil from 200 Dwarf nuts produced 7.1-8.4 L. The highest volume of oil (8.4 L) was resulted from SGD. The oil was generally having high medium chain fatty acid around 58.50-62.32% including lauric acid at 46.82-48.46%. The oil made from fruits of SGD contained the highest lauric acid around 48.46%, followed by RBD and BYD reaching 48.06% and 46.82%, respectively. It had a good smell, and fatty acid and moisture content were in accord with Indonesian National Standard. The coconut oil processed using the fruit of the SGD and RBD has a clear white color, while the BYD having clear yellow in color, like corn oil.

Abstract

Kopyor coconut is a naturally-occurring mutant having fluffy solid endosperm in stead of the normal one. Similar type of coconut has been found in several other Asian countries, with their distinct local names, such as Macapuno (Philippines), Makhrao Kathi (Thailand), Dikiri Pol (Sri Lanka), Thairu Thengai (India). It is a delicacy coconut to Indonesian and sells as much as ten times higher than normal coconut. In nature, three types of kopyor coconut exist in Indonesia: kopyor tall, kopyor dwarf, and kopyor hybrid. There are three kopyor dwarf varieties (‘Pati Kopyor Green Dwarf’, ‘Kopyor Yellow Dwarf’ and ‘Kopyor Brown Dwarf’) officially released, and one registered tall variety (‘Puan Kalianda Kopyor Tall’). In general, kopyor fruit yield under natural conditions is only < 25% of the total harvested fruits for both the tall and the dwarf types. Traditionally, Indonesian farmers harvest kopyor fruits at ten months after pollination while normal fruits at 11 months. They use the harvested normal fruits for propagation; but cannot guarantee whether or not they would produce korpyor fruit. Adoption of kopyor seedling production through embryo culture has been done. However, the seedling production is slow, while the price is very expensive, thus unaffordable to common farmers. Indonesian Palm Research Institute and Bogor Agricultural University have collaborated to develop alternative approaches to increase kopyor fruit production through the production of seedling that would ensure to produce korpyor fruit through control pollination. Initiated since 2010, the activities successfully overcome uncertainty in kopyor seedling production. Moreover, hybridization among local superior coconut varieties and known kopyor one have been done to broaden genetic background of kopyor trait and to develop breeding population for new kopyor varieties in the future. Overview and update of research progress on korpyor in Indonesia are presented in this paper.

Abstract

Coconut sugar is one of the high economic value products. The production of coconut sugar In Indonesia is about 300,000 tonnes/year. During the last few years, the supply of raw materials for the coconut sugar product has diminished due to stagnant production caused by the lack of coconut climbers collecting coconut sap. The scarcity of labor is caused by several factors, especially young tappers who are less interested in climbing tall coconut palms. To solve this problem, it is necessary to evaluate the potency of dwarf coconuts, with short trunk and fast fruiting. The objective of this study was the evaluation and selection of Dwarf coconut varieties that have high yield potential as a producer of sap and coconut sugar. The research was conducted in North Sulawesi Province by evaluating 9 Dwarf coconut varieties. The results of research on the production of coconut sap and sugar from 9 Dwarf coconut varieties with different plant ages, gave mixed results among coconut varieties. The length of tapping sap varied between 31.42 - 43.21 days/bunch, the volume of sap varied between 1.1 - 3.3 liters/tree/day, the pH of sap ranged between 6.49 - 7.86 and the Brix value varied between 14.01 - 17.64. The most important traits such as the sap yield and sugar production also varied from 14.54 to 18.95% among varieties, and between 0.16 to 0.42 kg/tree/day respectively. The Dwarf coconut varieties with the highest potential yield of sap and sugar are the Waingapu Red Dwarf (WRD), Salak Green Dwarf (SGD), and Nias Yellow Dwarf (NYD), with the potential sugar yield of 2.09 tons, 1.64 tons, and 1.56 tons/month/ha respectively. It is hoped that these Dwarf coconut varieties would be attractive for young tapers and could be introduced to farmers in several Provinces for tapping purposes for the production of coconut sugar.

Coconut seedlings are growing well with an important role in supporting the success of planting coconut in the field. The higher seed viability are growing well, the more the seed that grew into a coconut seedlings. This study aims to determine seed viability, growth and development of the Bido Tall coconut (DBO) seeds, Hybrid Dwarf x DBO and Khina-1. Coconut variety Bido Tall  is a coconut variety that was just released in 2017 originating from Bido village. This coconut has the advantage of large fruit, fast flowering, short stems,  and stalks slowly getting higher. The research was conducted at the Mapanget Experimental Garden, Indonesion  Palm Crops Research Institute from 2016 - 2018 using a single block method. The material used in this study is derived seed from coconut DBO, Hybrid Genjah x DBO, and Khina-1 coconut. The results showed that the viability seeds of Bido Tall coconut ranged from 73,15% - 88,10%, while the Hybrid Dwarf  x Bido Tall coconut 46,18% - 85,19%. Coconut seedlings do not all grow normally, there are some seeds were stunted (dwarf or a rosette), and the seeds are dead. Besides that, there are seeds that grow with two shoots (polyembriony) and dwarf. Characteristics of plant height, stem girth and leaves number of DB0 coconut are generally higher than Hybrid coconuts Dwarf x DBO and Khina-1. Hybrid Coconut GMW x DBO and GSK x DBO are the two best Hybrid coconut  that has characteristics of plant height, stem girth and leaves number close to or equal to the DBO coconut elders, which is more vigorous than other Hybrid coconuts included with the comparison Khina-1. Red Waingapu and Salak Dwarf coconuts are thought to be the best combining ability with DBO coconut.ABSTRAKBibit kelapa yang tumbuh baik mempunyai peranan penting dalam menunjang keberhasilan penanaman kelapa di lapangan.

Abstract

The objective of this research is to know the local tall coconut population, production and productivity in Taliabu Island, North Maluku Province, which is crucial for the industry. The aerial photography method using drones has been carried out to determine the distribution of coconut diversity, palm age, production potential and local coconut productivity. Production data and coconut fruit components were carried out on 6 sample populations. The result (Arvitech) revealed that in Jorjoga, the area under coconut was 335 ha out of the surveyed area of 1,066 ha. The total number of coconut palms was 55.728 palms. The Geomac survey carried out in Tabona indicated there were 77,629 coconut palms in an area of 1,000 ha. The fruit component analysis showed the weight of the whole fruit and the fruit without husk at the Jorjoga was 1,340-1,629g/fruit, and 805-1,033g/seed nut, and in Tabona was 1,478-1,577g/fruit and 944-966g/seed nut. The coconut production potential at Jorjoga was 9,539 nuts/ha/year, higher than that of Tabona with 7,227 nuts/ha/year. The coconut production and productivity estimation information can be used to develop a coconut replanting and rehabilitation strategy wherein selected varieties with good attributes for the tall coconut can be planted and ensure their proper maintenance, thus can be used to estimate the need for raw materials required for the establishment of the coconut industry in Taliabu Island. Determining the coconut population status can increase the production and productivity of coconut palms through rejuvenation, rehabilitation and expansion of coconut plantations using superior tall coconut seedlings.
