A brief study of economic value of sortimens candlenut wood (Aleurites moluccana sp.) in community forest, Maros, Indonesia

The difference in timber sorting is very influential on the level of farmer acceptance, especially in setting the basic price of sortimic wood which is not objective, causing the price of wood to be low so that the Income of farmers becomes low and results in investment that is less attractive for community forest development. This research is expected to be useful as a source of information for community forest managers in determining the form of sorting that can increase farmers’ yields or Income optimally. The sample of this study used the quota sampling method, namely farmers harvesting candlenut wood (Aleurites moluccana, sp.). Data collection was carried out through field observations and interview techniques regarding the costs of timber harvesting activities in community forests and the selling price of timber. While secondary data obtained from various sources such as research results, institutions, agencies related to this research. The analytical method used is to calculate the costs and revenues from timber harvesting for various sizes of wood sorting. Data analysis includes net Income and revenue. Based on the calculation results, it is obtained that the size of of candlenut wood is 400 x 10 x 20 cm can benefit farmers as much as IDR 651,875/m3. Community forest farmer’s should pay more attention to the selling price standards of candlenut wood so that the income increases even more. As for the other things that must be considered more in terms of plant maintenance so that wood quality is higher and maintained, and facilities and infrastructure related to harvesting activities can be maintained and updated so that harvesting activities can run smoothly.

Changes in the density, specific gravity and dimensional stability of candlenut wood (Aleurites moluccanus (L.) Willd.) from several variation temperatures with oil-heat treatment

Quality of inferior woods can be improved with wood modification technology. There are some wood modification technologies available, one of them is oil-heat treatment. Candlenut wood (Aleurites moluccanus (L.) Willd.) is one of low-quality wood species with limited utilization. Efforts to improve the properties of wood are needed for more optimal utilization. This research was conducted to improve physical properties of candlenut wood namely density, specific gravity, and dimensional stability by applying oil-heating treatment at various temperatures (160, 180 and 200°C) for one hour. Physical properties of wood were tested according to ASTM D143-94. The result showed candlenut wood in oil-heat treatment as better than control. Density and specific gravity of wood increased by 25.13% and 26.97%, respectively, and the dimensional stability also increased as well, shown by the reduction of hygroscopic properties of wood at tangential and radial directions by 22%. The best treatment selected for candlenut wood with temperature of 160°C.

The Effect of The Addition of Promoting Microbes (PROMI) In Making Media of Pleurotus ostreatus

In making oyster mushroom growing media, one of the stages that must pass is composting of growing media (baglog). At this stage, it takes a week or more to compile the media, so the media is ready to be inoculated by the fungus. This long composting time, economically slow down production in the cultivation of oyster mushrooms. Thus, using an activator to speed up the composting process is often done. During this time, the most widely used activators to shorten composting time is Effective Microorganism (EM4). In this study, another type of activator with the same function as EM4 was tried, namely Promoting Microbes (PROMI). The purpose of this study to determine the effect (dose) compromise on the making of oyster mushroom growing media to mycelium growth time, pinhead growth time; harvest time; the number of the fruiting body, and the weight of fresh mushrooms. The raw material used candlenut wood sawdust (Aleurites moluccana Willd) in the making of media. The method used in this study is the making of growing media, composting, sterilization, inoculation of the fungus, and maintenance. Growing media consisted of sawn wood sawdust, PROMI, bran, CaSO4, CaCO3, and water. The treatment used is the addition of compromise to the growing media before composting. The doses of PROMI given are as follows: 0 g (P1); 0.25 g (P2); 0.5 g (P3), and 0.75 g (P4), each of which dissolved in 200 ml of water. This study's results indicate that different PROMI when mixing raw materials influences the time of mycelium closure in growing media and the time of harvesting mushroom fruit bodies. For the time of mycelial closing, giving as much as 0.5 g, PROMI has different control effects. The provision of PROMI as much as 0.5 g and 0.75 g also influences the control in terms of harvest time.

Analysis of Calsium (Ca) and Potassium (K) Levels in Candlenut Shells (Aleurites moluccana Willd)

Candlenut shell (Aleurites moluccana Willd) is a waste produced from processing candlenut plants with a fairly hard texture. The use of candlenut shells as fertilizer, especially in Central Sulawesi, has not been done so much. The aim of this study was to determine the levels of calcium (Ca) and potassium (K) in candlenut shells. Calcium and potassium levels were determined using an atomic absorption spectrophotometer (AAS). The results show that the average calcium level in the candlenut shell is 0.315 ± 0.09%, while the average potassium level is 0.090 ± 0.01%. The results of Ca and K in candlenut shell are expected to be used as raw material for fertilizer production.

Agroforestry form and ecological adaptation in ancient Hawai'i: Extent of the pākukui swidden system of Hāmākua, Hawai'i Island

Agricultural strategies in ancient Hawai'i were adaptive, occasionally unique, and increasingly being shown to have strongly related to the local environmental opportunities and constraints. However, little is known about the extent of arboriculture and forest modification due to the lack of physical infrastructure and remains associated with these forms of agriculture. We utilize historical ethnography and remote sensing to examine the form and function of agroforestry along the Hāmākua coast on Hawai'i Island. Mapping over 26,000 remnant trees of two species used in Hawaiian agroforestry systems, we identify two distinct applications of arboriculture: A permanent arboricultural system with substantial breadfruit (Artocarpus altilis (Parkinson) Fosberg) and a shifting cultivation system based on candlenut (Aleurites moluccanus (L.) Willd). The distributions of these systems on the landscape appear to be constrained by soil fertility and temperature, with the swidden agricultural system occurring on the more fertile portion of the landscape and the permanent arboricultural system occupying the less fertile lands. Experimentation demonstrating the nitrogen accumulation and fixation associated with candlenut compost suggests that the swidden system would be maximized if the rotation occurred in the range of 6–12 years

Antibacterial Activity of Scopoletin from Stem Bark of Aleurites moluccana Against Salmonella typhi

Background: Based on a previous survey of ethnopharmaceutical studies (local culture), it was known that the use of decoction of candlenut stem bark (Aleurites Moluccana) was used as typhoid medicine in the treatment tradition of the people of East Kalimantan. In antibacterial screening by diffusion test, methanol extract of stem bark A.moluccana showed excellent growth inhibition of Salmonella thypimurium. Working method: Simplicia of A.moluccana stem bark was extracted by maceration using methanol. Maserate was extracted liquid-liquid using n-hexane and ethyl acetate solvents. The hexane and ethyl acetate fraction was monitored for active spots with TLC bioautography. The active compound is separated using vacuum liquid chromatography and radial chromatography. Results: The fraction J of KCV and J2 subfraction results from radial chromatography provides antibacterial activity of S. thpimurium. From the J2 subfraction obtained pure isolates in the form of yellowish needle crystals. The isolate was tested for antibacterial S.thypimurium using the microdilution method with a value of MIC is 250 µg/ml. Based on spectroscopic data and comparing the published spectra of the compound, the elucidation of the isolate is Scopoletin (7-hydroxy-6-methoxycoumarin).

Conservation Species of NTFPs Through Agroforestry for Community Livelihoods in Sikka, East Nusa Tenggara

Conservation and development of non-timber forest product (NTFPs) commodities in East Nusa Tenggara (NTT) are urgently needed. NTFPs are a source of livelihood for the rural communities around the forest areas. NTFPs development around the forest areas is needed as a means to create livelihoods and reduce poverty. The management strategy for forest areas based on integrating conservation and community welfare improvement is needed. The research aims to determine the NTFPs potency in Sikka Regency and the socio-economic conditions of NTFP farmers and to initiate the conservation and development of NTFPs based on the agroforestry approach. The research was conducted through literature review, secondary and primary data collection through surveys, interviews and field observations. The results of the study showed that tamarind (Tamarindus indica L.), candlenut (Aleurites moluccana (L) Willd.), areca nut (Areca cathecu L.), and betel (Piper betle L.) is the major of NTFP commodities in Sikka district. The socio-economic conditions of NTFP farmers on surrounding farmer are not prosperous yet, and highly depend on the sustainability of NTFP production. Community initiatives to conserve and regenerate NTFPs through agroforestry need to be improved, especially in improving the rate of plant growth. Technical assistance to increase community capacity in conservation and development of NTFPs around forest areas and private land is still needed.

Morphology and germination of the candlenut seed (Aleurites moluccana) from Samosir Island-North Sumatra

Aleurites moluccana or locally known as kemiri or candlenut is domesticated multipurpose tree species found in Indonesia, particularly in North Sumatra. As one of high economic value commodities, candlenut can be adopted as agroforestry species, windbreak, soil immobilization and land rehabilitation for critical land that can improve community livelihood with a variety of benefits. Information regarding seed characteristics of the candlenut in North Sumatra Province and its germination strategies is still limited, whereas this information are needed to support candlenut cultivation. Therefore, this research was conducted to obtain information on morphology and germination process of the seed of candlenut. Direct measurement and observation of seed were quantified to observe the seed morphology. The germination process is also quantified through direct observation. The results of seed morphology showed that the candlenut had rough elliptical shell shape with about 6.08 cm in diameter and the shell thickness was approximately 2.56 cm. Germination process took 4-5 months with hypogeal germination type.

Aleuritin, a novel dinor-diterpenoid from the twigs of Aleurites moluccanus with an anti-lymphangiogenic effect.

A phytochemical investigation of Aleurites moluccanus yielded one novel dinor-diterpenoid, aleuritin (1), along with a rare diterpenoid, aleuritone (2). Compound 1 has an unprecedented skeleton with a 6/6/5-fused tricyclic ring system. Compound 2 possesses a rare 6/6/5/3-fused tetracyclic skeleton, which is probably an artifact formed photochemically by the Norrish reaction. The structures of 1 and 2 were determined by spectroscopic methods (ECD, IR, mass, and NMR) and confirmed by single-crystal X-ray diffraction analyses. A plausible biogenetic pathway of 1 is proposed. Pharmacological study showed that these two compounds possessed mild in vitro anti-lymphangiogenic activity, which suppressed tube formation with IC50 values of 48.1 ± 1.8 and 34.2 ± 0.8 μg mL-1, respectively.

Weight loss supplement causing acute heart block in a child

A 16-year-old male was admitted to the paediatric ICU with acute onset of vomiting, somnolence, and chest pain, and electrocardiogram showing 2nd degree heart block after ingesting an Aleurites moluccana (Candlenut) seed as a herbal weight loss supplement. Electrocardiogram showed progressively worsening heart block with down-sloping of the ST segments, resembling digoxin toxicity. After 2 days of ICU observation, his symptoms began to improve and eventually resolved. The side effects of herbal supplements are often unknown but by analysing cases such as these, physicians can develop a better understanding of these substances to help guide management.

Application of Ziziphus Jujube (Red Date), Camellia Sinensis (Black Tea) and Aleurites Moluccana (Candle Nut) Marinades as Beef Meat Tenderizer

This study was carried out to analyse Ziziphus jujube (red date), Camellia sinensis (black tea) and Aleurites moluccana (candlenut) extract as the potential beef tenderizer. The beef meat chunks (3cm3) were marinated with the extracts at different concentrations (20%, 40% and 60%) for 24 hours at 4ºC. Both raw and cooked samples were subjected to physicochemical analyses and sensory evaluation. Overall, there were slight changes in pH values and increased in moisture content for all the treated samples. The increased concentration of extracts resulted in decreased cooking loss and the hardness from texture profile analysis (TPA) of the treated sample compared to the control. The colour analysis showed a significant (p&lt;0.05) different in term of lightness, redness and yellowness of all treated meat chunks. Increased concentration of extracts reduced the redness of meat samples. The sensory evaluation indicated that the tenderness, juiciness and overall acceptability of all treated samples were significantly (p&lt;0.05) higher compared to control. It can be suggested that the marination of meat with Ziziphus jujube (red date), Camellia sinensis (black tea) and Aleurites moluccana (candlenut) extracts have the ability to tenderize the meat as the toughness decreased in all treated samples with Ziziphus jujube (red date) was the best tenderizer.

The employment of FTIR spectroscopy and chemometrics for authentication of essential oil of Curcuma mangga from candle nut oil

The adulteration of high price oil such as essential oil of Curcuma mangga Val. (EOCM) with lower price oil is common to get economical profit. This study was to investigate the authentication of EOCM toward candlenut oil (CNO) using FTIR spectroscopy combined with multivariate calibration and discriminant analysis. The selection of CNO as adulterant oil model was due to its close similarity to EOCM in terms of FTIR spectra. Besides, EOCM has similar color with CNO, therefore, CNO is potential adulterant toward EOCM. Two multivariate calibrations of partial least square regression (PLSR) and principle component regression (PCR) along with FTIR spectra (normal versus derivatization) were optimized to get prediction models for quantification. The results showed that the combination of PLSR and normal FTIR spectra at optimized wavenumbers of 1614-1068 cm-1 was capable of predicting the levels of EOCM adulterated with CNO. Discriminant analysis was also success to differentiate the classification of EOCM and EOCM adulterated with CNO with accuracy levels of 100%. Using FTIR spectroscopy for oil authentication is rapid, simple without any chemicals, solvents, and sample preparation so that this technique is considered as a green analytical method.
