Abstract

Plants contain chemical compounds that are used as natural medicinal ingredients as antioxidants and have the potential to act as free radicals. Cocoa plants are rich in polyphenols such as flavanols, which have antioxidant and anti-inflammatory properties against degenerative diseases. The aim of the research is to determine whether variations in drying temperature of cocoa bean ethanol extract (Theobroma cacao L.) affect antioxidant activity. This research is in the form of experimental research carried out in a laboratory. The drying method uses an oven for 8 hours at temperatures of 40, 50, and 60ºC. The dried cocoa beans were extracted using the maceration method using ethanol solvent. Antioxidant analysis in this study used the ABTS [2,2-azino-bis(3-ethyl-benzothiazolin-6-sulphonic acid)] method with a microplate reader at a wavelength of 630 nm. The value used to determine antioxidant activity was the IC50 value. All samples BKS 40, BKS 50, and BKS 60 had air contents of 49.34%, 32.7%, and 24.32%. The results of this study prove the antioxidant activity of cocoa bean ethanol extract (BKS 40, 50, and 60) is included in the strong category with IC50 values 86, 88, and 71 μg/mL, respectively. The results prove that temperature does not affect antioxidant activity.

Abstract

Kasa adalah kondisi klinis yang didefinisikan dengan jelas seperti batuk, dan patofisiologisnya terkait erat dengan mekanisme refleks batuk dalam pengobatan modern. Trikatu adalah ramuan yang mengandung tiga bahan herbal dengan rasa pedas, yaitu maricha (black papper), Peepli (long pepper), dan Sunthi (Ginger). Komposisi dari Trikatu terbukti efektif dalam pengobatan Kasa. Perawatan khas dalam mengatasi gejala bronkitis akut, seperti pneumonia dan asma, terbukti tidak efektif, dan Badan Pengawas Obat dan Makanan Amerika Serikat menyarankan untuk tidak menggunakan obat batuk dan pilek pada anak di bawah enam tahun. Pengobatan alternatif perlu dilakukan. Oleh karena itu, pada penelitian ini formula sediaan Trikatu ditransformasikan ke dalam pengobatan Kasa berupa minyak herbal menggunakan VCO, rimpang jahe merah (Zingiber officinale Roxb.), buah kering cabai jawa (Piper retrofractum), dan buah kering merica hitam (Piper nigrum Linn). Formula minyak Trikatu menggunakan metode digesti dengan variasi suhu dan waktu. Tujuan dari penelitian ini adalah untuk mengetahui kandungan senyawa minyak Trikatu terbentuk akibat variasi suhu dan waktu digesti dengan GC-MS. Senyawa  bioaktif utama yang dihasilkan pada minyak Trikatu dengan variasi suhu dan waktu digesti yaitu octanoic acid, n-decanoic acid, caryophyllene, α-curcumene, dodecanoic acid, zingerone, tetradecanoic acid, n-hexadecanoic acid, α-Monolaurin, oleic acid, dan piperine. Hasil penelitian menunjukkan bahwa suhu dan waktu digesti berpengaruh terhadap keberadaan senyawa dalam pembuatan minyak Trikatu. Semakin lama waktu digesti yang digunakan dalam pembuatan minyak Trikatu, maka kandungan asam lemak tak jenuh dan jenuh akan semakin meningkat.

Abstract

This study aims to evaluate the differences in phytochemical profiles and antioxidant activity between the methanol extract of cocoa beans and the n-butanol fraction obtained from Jembrana, Bali. Maceration technique was used in this research. The crude extract of cocoa beans was partitioned based on polarity to determine which fraction has the most potential as a source of bioactive compounds. The n-butanol fraction was evaporated to obtain a polar fraction from the methanol extract of cocoa beans. UV-Vis spectrophotometry was used to measure the total content of flavonoids and tannins in the methanol extract of cocoa beans and the n-butanol fraction. Research found that the methanol extract of Balinese cocoa beans had a total flavonoid content of 0.34 g/100 g and tannins of 0.37 g/100 g. However, the n-butanol fraction had a total flavonoid content of 15.34 g/100 g and tannin 20.16 g/100 g. The IC50 value of the methanol extract was 29.66 ?g/ml, while the n-butanol fraction was 2.63 ?g/ml. The AAI of the methanol extract was 1.35 and the n-butanol fraction was 2.63, indicating that the n-butanol fraction had stronger antioxidant activity with higher flavonoid and tannin content than the methanol extract. The implication of this research is that the n-butanol fraction of cocoa bean methanol extract has the potential as a source of bioactive compounds that can be utilized in the development of high added value products, especially in the context of food pharmaceuticals or other health product.

Abstract

The problems faced by the Abasan community are that both young and old people often experience muscle aches and pains and have low knowledge of the use of herbal rubbing oil, as well as low interest in making their own herbal rubbing oil. Based on these problems, the community service team provided solutions in the form of socialisation on the use of herbal rubbing oil and teaching the community how to make herbal rubbing oil. This community service method is based on three areas. First, the production area: conducting lectures and discussions on what partners need so that the production process of herbal rubbing oil can run normally. Second, the management area: teaching participants how to make herbal rubbing oil that is good for health. Third, the marketing field, which involves teaching participants how to sell massage oil products at affordable prices so that many people will buy them by making the packaging and labels attractive. This community service activity took place on Sunday, 1 June 2025, at the Rare Asrama Banjar Abasan Early Childhood Education Centre. The event was attended in person by residents of Banjar Abasan, Singapadu Tengah Village, Sukawati Sub-district, Gianyar Regency, Bali. During the socialisation phase, the speaker was Mrs Ni Made Sukma Sanjiwani, S.Si., M.Si. Mrs Sukma explained the use of herbal ginger and VCO massage oil for health purposes. During the demonstration stage, conducted by lecturers and students, the lecturer taught participants how to make herbal massage oil using VCO and ginger. The initial step involved blending the ginger, then mixing it with a small amount of VCO, stirring it, and squeezing it. The ginger pulp was then mixed with a small amount of VCO and squeezed again. The ginger extract obtained is then mixed with mint oil and eucalyptus oil, with additional VCO added until the calibration mark is reached. The lecturer also labels the herbal massage oil bottles with stickers to improve the packaging, which can be used as an example for participants to make and sell the oil themselves, potentially turning it into their own business
