Abstract. Minyak simplah adalah produk lokal Aceh dari proses fermentasi kelapa yang mempunyai manfaat seperti minyak kelapa murni (VCO). Tujuan penelitian ini adalah untuk mengetahui pengaruh pemanasan energi mikrowave terhadap kualitas minyak simplah berdasarkan variasi volume minyak. Metode yang dilakukan adalah memanaskan minyak simplah dalam mikrowave oven frekuensi 2,450 MHz selama 60 detik dengan energi 800W pada variasi volume yakni 20, 40,dan 60 ml, dengan 3x ulangan. Pengamatan dilakukan terhadap suhu, kadar air, derajat keasaman, asam lemak bebas, bilangan peroksida dan warna. Hasil penelitian menunjukkan bahwa perlakuan variasi volume minyak pada pemanasan mikrowave selama 60 detik meningkatkan suhu minyak secara signifikan, namun perlakuan tersebut tidak memberikan pengaruh nyata terhadap kadar air, pH, asam lemak bebas dan bilangan peroksida. Kualitas minyak simplah sebelum dan setelah pemanasan dengan mikrowave belum memenuhi standar sehingga penelitian lanjutan sangat diperlukan untuk mengkaji kemungkinan peningkatan kualitas minyak menggunakan energi mikrowave dengan memperlama waktu pemanasan.The Influence of Oil Simplah Volume to Its Quality under Microwave HeatingAbstract. The simplah oil, contained a lot of benefits as virgin coconut oil (VCO), is traditionally produced during fermentation of coconut by Acehnese. The purpose of this study is to determine the influence of microwave heating on the simplah oil quality based on the variation of its volume. The study was conducted by heating the simplah oil by using a microwave oven at frequency of 2.450MHz for 60s at power level 800W under the variation of oil volume i.e. 20, 40, and 60 ml in three replications. The parameters observed were temperature, water content, degree of acidity, free fatty acids, peroxide number and color. Results showed that the variation of oil volume after microwave heating had significant effect on temperature, but did not significantly influence the rest parameters. Since the quality of simplah oil before and after treatment did not meet the standard yet, it is very important to conduct the further study by extending the exposure time of the oil under microwave heating.

Virgin coconut oil (VCO) is a pure coconut oil made from mature and fresh coconut meat. VCO is consumed for health-related reasons, but the unsaturated fatty acids of VCO are prone to oxidation. Mixing VCO with peppermint oil, which contains antioxidants, inhibits the oxidation of unsaturated fatty acids and thus prevents the rancidity of VCO. This research used the antioxidants from peppermint oil to improve VCO quality. VCO contains antioxidants, such as α-pinene, menthol, 1,8-cineol, camphor, flavonoid, borneol, tocopherol, and carotene. The treatments consisted of three peppermint oil concentrations (2.5%, 5%, and 7.5%) in VCO. Results showed that the additionof peppermint oil significantly improved VCO quality. The optimal concentration of peppermint oil in VCO was 7.5% with a water content of 0.05%, a free fatty acid value of 0.13%, a peroxide value of 0.53 mg eq/kg, an iodine value of 4.42 g I2/100 g, a total plate count of 0 cfu/mL, and antioxidant activity of 90.28%.

Background: Coconut oil is an edible oil obtained from fresh, mature coconut kernels. Few studies have reported the anticancer role of coconut oil. The fatty acid component of coconut oil directly targets the liver by portal circulation and as chylomicron via lymph. However, the anti-cancer activity of coconut oil against liver cancer cells and oral cancer cells is yet to be tested. The active component of coconut oil, that is responsible for the anticancer activity is not well understood. In this study, three different coconut oils, Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO), were used. Objective: Based on previous studies, it can be hypothesized that fatty acids in coconut oil may have anticancer potential and may trigger cell death in cancer cell lines. Methods: Each cell line was treated with different concentrations of Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO). The treated cells were assayed by MTT after 72 hr of incubation. The fatty acid composition of different coconut oils was analyzed by gas chromatography. Result: Different concentrations of coconut oils were used to treat the cells. Interestingly, the anticancer efficacy of VCO, PCO and FCO was not uniform, rather the efficacy varied from cell line to cell line. Only 20% VCO showed significant anticancer activity in HepG2 cells in comparison to 80% PCO against the KB cell line. Remarkably, 20% of PCO and 5% of FCO showed potential growth inhibition in the KB cell line as compared to 80% PCO in HepG2 cells. Moreover, there was a difference in the efficacy of VCO, PCO and FCO, which might be due to their fatty acid composition. Comparing the anticancer efficacy of VCO, PCO and FCO in this study helped to predict which class of fatty acids and which fatty acid might be associated with the anticancer activity of VCO. Conclusion: This study shows that VCO, PCO and FCO have anticancer efficacy and may be used for the treatment of cancer, especially liver and oral cancer.

Chronic kidney failure is a public health problem throughout the world, and the number of sufferers is increasing. Chronic kidney failure can cause clinical symptoms in various body systems, one of which is a disorder in the skin that becomes dry (uremic). This study aimed to examine the effect of Virgin Coconut Oil (VCO) on the skin moisture among uremic patients undergoing hemodialysis. This type of research is a quasi-experiment with pre-test and post-test equivalent control group. The study was conducted at the Regional General Hospital, Dr. RM. Djoelham Binjai. The study population was 80 people, divided into 2 sample groups of 40 people each. The results showed that there was a significant effect of skin moisture on the intervention group before and after being given Virgin Coconut Oil, p = 0.000<0.05; There was a significant effect of skin moisture in the control group before and after lotion (post-test), p = 0.000<0.05. There is no need for special emulsions such as VCO to moisturize the skin in uremic patients undergoing hemodialysis because using ordinary lotions can moisturize the skin. It must be used regularly, twice a day after bathing. The lotion used must also be a lotion that does not contain mercury and chemicals that can harm the skin. To increase the skin's moisture becomes normal, giving lotion is better than VCO because by providing lotion, more skin becomes normal, while using VCO, the skin becomes more oily. It is recommended to health workers (doctors, nurses) to practice correctly and appropriately how to administer Virgin Coconut Oil (VCO) to uremic patients undergoing hemodialysis to be done at home

Salinity stress is a limiting factor for the growth and yield quality of rapeseed. The potentiality of melatonin (MT; 0, 25, 50, and 100 µM) application as a seed priming agent in mediating K+/Na+ homeostasis and preventing the salinity stress mediated oxidative damage and photosynthetic inhibition was studied in two rapeseed cultivars. We found that 50 µM MT treatment imparted a very prominent impact on growth, metabolism of antioxidants, photosynthesis, osmolytes, secondary metabolites, yield, and fatty acids composition. Days required for appearance of first flower and 50% flowering were decreased by MT application. Exogenous MT treatment effectively decreased the oxidative damage by significantly declining the generation of superoxide and hydrogen peroxide under saline and non-saline conditions, as reflected in lowered lipid peroxidation, heightened membrane stability, and up-regulation of antioxidant enzymes (catalase, superoxide dismutase, and ascorbate peroxidase). Furthermore, MT application enhanced the chlorophyll content, photosynthetic rate, relative water content, K+/Na+ homeostasis, soluble sugars, and proline content. Moreover, MT application obviously improved the oil quality of rapeseed cultivars by reducing glucosinolates, saturated fatty acids (palmitic and arachidic acids), and enhancing unsaturated fatty acids (linolenic and oleic acids except erucic acid were reduced). Yield related-traits such as silique traits, seed yield per plant, 1000 seeds weight, seed oil content, and yield biomass traits were enhanced by MT application. The anatomical analysis of leaf and stem showed that stomatal and xylem vessels traits are associated with sodium chloride tolerance, yield, and seed fatty acid composition. These results suggest the supportive role of MT on the quality and quantity of rapeseed oil yield.
