Texte intégralRésumé :
<p class="A04-abstrak2"><span>Coconut commodity has a strategic role in the country's foreign exchange earnings, providing employment and increasing farmers' income. In 2020 the value of Indonesia's coconut exports reached US$890 million, with a total export volume of 1.8 million tons. The most significant export value is processed coconut oil, namely crude coconut oil and semi-finished coconut oil, by 50% of other processed coconut products. The export value of processed crude coconut oil was 29% or US$254.9 million, and semi-finished coconut oil was 21% or US$188.1 million. This paper reviews the performance and problems of coconut Indonesia's industry and identifies opportunities for its development. The coconut industry performance faces problems from upstream to downstream. The upstream problems are low productivity, old plants, limited capital resources, damaged plants, and decreasing land area. The downstream issues are the lack of innovation in coconut products, fresh coconuts dominating coconut exports, and the decline in export performance for processed products of crude oil and semi-finished oil. Innovation and technology are necessary to enhance the coconut industry's performance. Produce ready-to-use products that are increasingly in demand in global and domestic markets. Productivity improvements, production costs, and quality are determinants of the competitiveness and yield of coconut exports.</span></p>

Texte intégralRésumé :
It is based on the fact that small-scale coconut oil processing in micro-scale businesses is facing serious threats and competition with palm oil produced by large and medium-sized entrepreneurs, resulting in a downturn in business as well as weakening the motivation of coconut farmers to process coconut production into coconut oil. As a result, coconut farmers in their daily lives actually buy palm oil processed by large and medium entrepreneurs, while their businesses are getting worse. In line with this, through this research, an analysis of the obstacles and opportunities for the development of the people's coconut oil processing industry was carried out. The purpose of this study was to analyze the barriers to developing the people's coconut oil processing industry on a micro-scale business and to analyze the opportunities for developing the people's coconut oil processing industry on a micro-scale business. The research method is through a Focus Group Discussion (FGD) to identify obstacles and opportunities for developing the coconut oil processing industry, followed by Analysis Hierarchy Process (AHP) to determine priority problems and priority opportunities that should be carried out by multi-stakeholders for the development of the coconut oil processing industry. The results showed that the priority obstacles to the development of the coconut oil processing industry in micro-scale businesses in Konawe Islands Regency were product marketing problems, financial capital, and business funding problems, production equipment problems, skilled labor issues, raw material problems, micro-business protection policy issues, business organization, and management problems, as well as problems in the use of information technology and innovation. The priority of opportunities for the development of the micro-scale coconut oil processing industry in Konawe Kepualauan Regency is the presence of economic value by-products of coconut oil processing, namely shell charcoal, nata de coco, and coconut coir, there is a tendency for people to consume more coconut oil than consume coconut oil. Palm oil, the existence of a government program to encourage the coconut processing industry, and the nutritional value that is unique to coconut oil. Organizational and business management problems, as well as problems in the use of information technology and innovation.

Texte intégralRésumé :
Background: Coconut oil, or copra oil is obtained from the nut/kernel of matured coconuts garnered from the Cocosnucifera. Coconut oil is an edible oil derived from the kernels of harvested mature coconuts harvested from the coconut palm. In recent decades, this oil has risen to the status of a health food superstar in the health food industry. Celebrities are welcoming its use, nutritionists are promoting it, and patients are praising it for its many benefits. Purpose: This oil has been linked to a range of health advantages. These include improvements in skin care, hair care, stress management, losing weight & cholesterol level management, immune modulatory effects, cardiovascular applications, and, most recently, Alzheimer’s disease. However, for several years, coconut oil was demonised, and consumers were led to believe that it was harmful to their health because it would clog arteries and cause heart disease. The tide has shifted, and in recent years, increased awareness of the favourable health advantages of coconut oil has emerged. Conclusion: The usage of coconut oil, particularly crude coconut oil, is increasingly popular; however some individuals are still doubtful. This present review makes an attempt to provide a scientific assessment of the medicinal qualities of this oil.

Texte intégralRésumé :
Coconut is one of the most commercially important crops in Sri Lanka. The country requires around 3,600 million nuts per year to meet the current demand. However, the current annual production ranges between 2,500 and 3,100 million nuts, indicating a shortage in nut production. This study aims to investigate the impact of declining coconut production in Sri Lanka on kernel-based export products and coconut oil (excluding export). The study involved collecting primary data through a cross-sectional survey. This included interviews with 120 kernel-based exporters, palm oil importers, and dehydrated chip-importing millers. The participants were selected using stratified purposive sampling, and three semi-structured questionnaires were administered. In addition, secondary data was gathered from the Coconut Development Authority. The ARIMA (2, 1, 1) model was utilized to forecast potential fluctuations in coconut production in Sri Lanka over the next 5 years, aiming to determine whether production would range between 2500-3000 million nuts. The model projects nut production to be 2,626, 2,833, 2,978, 2,850, and 2,761 million nuts for the respective years. The Friedman test confirmed a significant difference (P<0.05) among the statements related to the sustainability of raw material supply and the sustainability of final product supply of kernel-based products for the export market. According to the statistical analysis, the production of kernelbased export companies would be affected by a decrease in annual nut production. However, they would continue to export even if the annual nut production decreases due to their strong supplier base. The study found a significant difference (P<0.05) in the impact of imported dehydrated chips. The research revealed that due to most existing coconuts being used in the milk industry, millers were unable to meet the demand for coconut oil because of a shortage of raw materials. The findings of this study propose to develop and implement strategic plans to address the projected decline in nut production in Sri Lanka and to create comprehensive strategies for the equitable distribution of coconut resources to support both domestic and international coconut-based industries.

Texte intégralRésumé :
Coconut commodities that have been processed into copra or oil are less strategic to develop because they compete with palm oil and other vegetable oils such as soybean oil, sunflower nuts. As a result, the price of coconut oil, although the upward trend, but fluctuates greatly. To minimize the effects of price fluctuations, it is necessary to diversify utilization and processing. In addition to being edible oil, coconut oil can be further processed into oleochemical products. Important oleochemical products are fatty acids, fatty acid methyl esters, fatty acid alcohols, and glycerin. A possible problem is competition with Asia Pacific countries that are also developing the oleochemical industry. This paper aims to present technological introductions of some high economic value oleochemical products such as fatty acids, fatty acid methyl esters, fatty acid alcohols, and glycerin. Systematic writing approach in the form of a review based on literacy as a secondary data source. The oleochemical industry entering the industry 4.0 era is quite prospective to be developed in Indonesia to achieve the optimal economic value of coconuts in terms of availability of raw materials and technological innovation, technical excellence, employment, and domestic and foreign market opportunities.

Texte intégralRésumé :
Virgin coconut oil (VCO) is derived from fresh coconut fruit and offers numerous health benefits, such as preventing heart diseases, improving digestion, reducing fat accumulation, and more. VCO contains medium-chain fatty acids that are easily digested and metabolized by the body, preventing fat buildup. Additionally, it is rich in antioxidants like tocopherols and beta-carotene, which help prevent premature aging and maintain vitality. The phenolic content in VCO can be influenced by the processing method and the age of the coconuts used. Therefore, this research examined the impact of processing methods on the quality of phenolic content as a product of the pharmaceutical industry. The largest group of phenolic compounds includes tocopherols, sterols, and flavonoids. Phenolic compounds in coconuts are primarily located in the coconut fruit’s epidermis. VCO produced from coconuts with the epidermis or coconut fruit’s outermost layer contains a higher concentration of phenolic compounds compared to VCO produced from coconuts without the epidermis. The research involved defining and refining the problem, formulating hypotheses or tentative answers, drawing conclusions, and conducting meticulous testing of all conclusions to determine their alignment with the hypotheses. In this study, the researchers compared the quality and phenolic compound content of virgin coconut oil (VCO) by sampling from several small and medium enterprises in various regions, specifically in the Island of Sulawesi. The findings revealed that each graph represents the percentage of five samples, depicting various contents, such as water content, free fatty acids, peroxide value, phenolic compounds, and antioxidant activity

Texte intégralRésumé :
This thesis explores three topics relating to price transmission in economic theory. The broad aim is to understand the price adjustment processes of the domestic and export coconut markets of Sri Lanka during the 1980 to 2012 period. The three topics investigated were the changing role of coconut oil exports due to changes in the global oil markets. Second the functioning of the domestic district coconut markets and finally the impact of the tsunami 2004 on the coastal district coconut markets. The analytical framework for the study is the economic theory of the Law of One Price. The first issue was examined using cointegration, vector error correction and impulse response methodologies. To address the function of the domestic district coconut markets at wholesale, retail and vertical levels Hansen and Seo econometric model was used. To test the effects of the tsunami on the coastal district coconut markets and to assess whether “rockets and feathers” phenomenon rose as a result of the tsunami Enders and Siklos econometric model was applied. The results confirmed that cointegration pattern of vegetable oils in the international market changed with the emergence of bio fuel around 2000. Cointegration of coconut oil with other oils also did change with the emergence of biofuel. The results of the domestic market showed that Colombo market was cointegrated with district coconut markets. . The results of market structures at all levels showed mixed results with more symmetrical markets at wholesale level and more asymmetric markets at the vertical level Results of the impact of tsunami showed that markets were disrupted unevenly with highest disruption in the vertical markets due to tsunami. The tsunami does not seem to have lead to rocket and feather phenomenon.

Texte intégralRésumé :
AbstractLightweight concrete (LWC) has been used for more than 2000 years, and the technical development of waste-based LWC is still proceeding. Notably, the very first representative concrete mix of infrastructural LWC was introduced for building a family house in Berlin, Germany, a few decades ago. The unique and distinctive combination of waste-based LWC successfully creates an appealing alternative to traditional concrete aggregates in terms of durability, robustness, cost, energy-saving, transportation, environmental advantages, innovative architectural designs and implementations, and ease of construction. Numerous researchers have attempted to utilize waste materials to produce LWC, aiming to bring both ecological and economical solutions to the construction industry over the past few decades. Waste materials, such as crushed glass, waste tire rubber, masonry rubber, chip rubber, plastics, coconut shells, palm oil fuel ash, palm kernel shells, fly ash, and rice husks, possess lower specific gravity than traditional concrete aggregates. Thus waste-based LWC can be a significant replacement for conventional raw materials (cementitious material and aggregates) as it requires less strength than conventional concrete for both structural and non-structural applications. Although waste-based LWC is well recognized and has proven its scientific potential in a broad range of applications, there are still uncertainties and hesitations in practice. Therefore, the primary objective of this study was to demonstrate the current state-of-the-art understanding and advancement of waste-based LWC over the past decades. Furthermore, an equally critical discussion is reported to shed light on the potential benefits of LWC. We highlight how the performance of LWC has been enhanced significantly over the period, and understanding of the properties of waste-based LWC has advanced.

Texte intégralRésumé :
In response to the worsening crisis on energy security and climate change, the Philippine Biofuels Law (Republic Act 9367) was enacted which mandates the blending of biodiesel to petroleum diesel sold in the country. Primarily, feedstock and pricing concerns led to stagnant growth of the Philippine biodiesel industry. Hence, viability of different potential biodiesel feedstocks such as coconut, oil palm, and soybean (first generation), jatropha and used cooking oil (second generation), and microalgae (third generation) was assessed through extensive research and developments. Among these sources, oil palm is regarded as the best complementary feedstock to coconut due to its high biodiesel productivity of 376 million liters per year. Oil palm biodiesel production in the Philippines was also found to have a low carbon footprint of 1.80 kg CO2e per liter and a GHG reduction potential of 42%, which corresponds to a GHG savings of about 1.05 million metric tons CO2e per year for a 5% blending mandate in 2025. Additionally, a low biodiesel selling price of about Php 33.26 per liter can be achieved from using this feedstock for biodiesel production. Hence, use of a low cost and readily available feedstock coupled with established processing technologies and pricing mechanisms will help boost the biodiesel industry in the Philippines.

Texte intégralRésumé :
The induction phase is the first step of oxidation, after which initiation phase occurs and is characterized by 1H abstraction and increasing peroxide levels. Later, the propagation cascade phase is generated with significant chemical and structural modification of the oil's fatty acids, causing increased concentrations of aldehydes. The process is terminated by the formation of toxic polymerization end products. A rapid and efficient analytical method of the different steps of oil oxidation are herein describe. Using a TD 1H NMR sensor capable of measuring proton mobility, it is possible to follow the segmental motion of the 1H population in each of the oil's segments, as well as describing the proton relaxation signals generated from the magnetic field that can measure and characterize important chemical and physical properties of the tested sample. In our research group's recent work, we demonstrated the ability to quantitatively measure the rates of self-diffusion (D) as well as ILT T1 and T2 spectral fingerprints of heated oils to correlate these values with chemical and morphological changes during oxidation. To simplify and reduce the time required for characterizing oil quality and oxidation using a TD 1H NMR sensor the present study focused on the relationship between D and the thermal and air conditions for enhancing oil oxidation. An excellent (R2>0.95) correlation of D with oil oxidation's conventional colorimeter standard tests (e.g., PV, p-Anisidine and TOTOX) was shown. These results were obtained from a high temperature (80°C) oxidation study of a list of saturated, monounsaturated and polyunsaturated edible oils (linseed, soy, olive, coconut, butter, respectively). The study clearly showed that self-diffusion D values, reflecting the mobility of 1H protons, is an accurate and rapid (< 1 minute) marker/indicator for the oil's quality with emphasis on the oils oxidation status, that be measured and used in the oil industry.

Texte intégralRésumé :
Most traditional fats for the food industry take hydrogenated oils and high saturated oils as the base material. However, hydrogenated oils and high saturated oils were widely questioned because of the threat to health caused by trans and saturated fatty acids. Oleogelation is a potential strategy to structure liquid oils to replace traditional fats in foods. The aerogel-templated method allowed plant-derived polymers (polysaccharides and proteins) to prepare oleogels. Methyl-cellulose and xanthan gum were dissolved in waters and aerated to prepare aqueous foams. The molecular network of polysaccharides in aqueous foams was rapidly fixed by the ultra-low temperature freezing method, and aerogels were obtained by freeze-drying. The ultra-low temperature freezing method made aerogels have an average pore size of 36.7 μm and improved the porosity. Because of the open network in aerogels, there was a gap between oleogels fabricated by aerogels and traditional fats. Hence, fat crystals were used to further enhance the network structure in oleogels. Vegetable fats (Palm oil, coconut oil, palm kernel oil, and palm kernel stearin) were used to replace 50% of the soybean oil to enhance oleogels made by the aerogel-templated method. Aerogels had stronger oil absorption ability for oils containing PKS and PKO, reaching 39.6 and 38.24 g/g, respectively. Enhancement effects of different vegetable fats on oleogels were analyzed by the oil binding ability, polarized light microscopy, and rheological test. The crystal network formed by coarse crystals could endow oleogels with higher oil binding ability and more robust solid properties but result in more sensitivity to temperature. Through FTIR analysis, the hydrogen bond between polysaccharides constituting the polymer network was detected. The addition of vegetable fats could make oleogels physical properties of traditional fats, thus making oleogels further in the traditional fat replacement.

Texte intégralRésumé :
The solid fat content (SFC) is responsible for the characteristics and properties of a variety of fat-based food products, since it provides information, among others, on physical appearance, organoleptic properties, spreadability, product stability mouth feeling, and plasticity. The traditional techniques to measure SFC, such as pulsed nuclear magnetic resonance and differential scanning calorimetry, require expensive instrumentation and trained personnel. Nowadays innovative techniques are needed for fast, automatic, and low-cost in situ, determination of SFC directly in the production lines to allow food quality monitoring in control industrial processes. This is very relevant for small and medium food industries that cannot afford an internal quality control laboratory. An innovative near-infrared analytical approach to measure SFC in vegetable fats and oils is herein presented. The method is based on single-wavelength (835 nm) and measures the sample optical attenuation during a thermal cycle (featuring both heating and cooling). An estimation of SFC is then made from the measured optical data. Samples were a set of 16 different vegetable fats and oils commonly used in the food industry, such as cocoa butter, refined and fractionated coconut oils, hydrogenated palm and soybean oil, as well as blends among them. The estimated temperature corresponding to an SFC of 80%, 60%, 40%, and 20%, respectively, was plotted versus the corresponding temperature resulting from DSC curves for all tested samples. The experimental results obtained with such a method agree with those provided by DSC at different temperatures (R2 > 0.9), thus reaching a good SFC estimation. This indicates that the single-wavelength near-infrared technique is promising for practical analysis in the production lines to assess the quality of vegetable fats and oils. The herein-tested analytical solution could be implemented in the form of a low-cost and portable electronic system.
