Abstract

The quality of palm oil is strongly influenced by temperature. The oxidation of palm oil can be caused by high temperatures. The higher the storage temperature, the faster oxidation occurs. In this research, the temperature significantly affects the quality of several palm oil derivative products such as Palm Olein, Palm Stearin, Palm Kernel Oil, and Palm Kernel Stearin. Antioxidants are very effective in resisting the increase in the oxidation reaction of some palm oil commodities. With the addition of tertiary butylhydroquinone (TBHQ) or butylated hydroxytoluene (BHT), the increase in peroxide value, p-anisidine values, free fatty acid, color tends to be slower than without the addition of antioxidants. For PV, BHT was the most effective antioxidant for RPKOL at a 29.75% increase, RBDOL at 9.91%, and RBDST at 5.26% but for RPKS TBHQ was the most effective increase at 19.83%. For anisidine value, TBHQ+BHT was most effective for RPKOL with a 61.62% increase, TBHQ for RPKS with 76.76%, BHT for RBDOL and RBDST with 15.37% and 14.46%. In the FFA test, BHT was effective for RPKOL and RPKS with a percentage increase of 6.48% and 6.67%, but TBHQ was effective for RBDOL and RBDST to controlled FFA with an increase of 8.41% and 3.38%. In color testing, TBHQ proved to be the effective antioxidant for RPKOL and RBDOL, resulting in percentage increases of 8.71% and 2.13%, respectively. For RPKS, the combination of TBHQ and BHT was employed, resulting in no percentage increase (0%). Additionally, BHT at 3.85% was used for RBDST. At a temperature of 130°C, an oxidation process was observed, indicating the formation of an aldehyde compound. This was evidenced by the FT-IR spectrum, showing peaks at wave numbers 1760 cm⁻¹ (C=O of aldehyde) and 2900 cm⁻¹ (CH on aldehyde). In this research, we can also see the formation of trans fatty acids C18:1n9t in GC-FID's peak area

Abstract

Sappan wood (Caesalpinia sappan L.) from the Caesalpiniaceae family is a plant that has been widely used as a health drink such as herbal medicine, in Sundanese called jamu or wedang secang. The drink containing C.sappan extract is traditionally believed to have the ability to reduce symptoms of colds, coughs, canker sores, and rheumatism, overcome fatigue and improve blood circulation. In this research, wood extract of C. sappan L in acetone solvent tested as antibacterial and anticancer. The antibacterial test was performed on the bacteria Streptococcus mutans ATCC 35668 and Enterococcus. faecalis ATCC 49619 with paper disc diffusion method. The microdilution method was used to determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). The anticancer test is carried out in vitro on A549 lung cancer cells using the MTT method assay. The results showed that the wood extract of C. sappan L in acetone has weak antibacterial activity against S. mutans ATCC 35668 and E. faecalis ATCC 49619. The MIC is 1250 ug/mL, respectively. Aceton wood extract of C. sappan L. showed moderate anticancer activity with IC50 value 90,01µg/mL. Thus, the extract of C. sappan L. in acetone has the potential as a source of anticancer compounds.
