“…AV is an important indicator when evaluating the oxidation stability of edible oil [26] . The AV of CK-HOPO was 1.65 mg/g, which was significantly higher than that of WR-Res-HOPO, RP-Res-HOPO, MRP-Res-HOPO, URP-Res-HOPO, and MURP-Res-HOPO samples.…”

“…( 2018) melaporkan bahwa minyak kemiri sunan memiliki kadar air 9,6 %. Kadar air dari minyak kemiri sunan pada penelitian lain dilaporkan sebanyak 21% (Abduh et al, 2019) dan 0,51% (Haryono dkk., 2020). Perbedaan kadar air dari minyak kemiri sunan tersebut disebabkan oleh berbagai faktor, seperti iklim lingkungan, cara dan kondisi penyimpanan biji kemiri sunan, dan metode ektraksi minyak (Ali et al, 2014).…”

Kemiri sunan oil is non-food oil. Kemiri sunan oil can be a potential raw material for biodiesel synthesis. Kemiri sunan oil has relatively high free fatty acid content so that before the transesterification stage, it is necessary to lower the levels of free fatty acids through an esterification reaction. In esterification, the moisture content in oil and fat as raw material for biodiesel affects the conversion rate of free fatty acids into biodiesel, so this needs to be studied. The purpose of this study was to study the effect of the moisture content in kemiri sunan oil on the conversion of free fatty acids into biodiesel at the esterification stage. The moisture content in kemiri sunan oil was varied through the evaporation step at 105°C for 1, 1.5 and 2 hours' time variations. Kemiri sunan oil with various moisture content was further esterified at 60°C, the mole ratio of oil to methanol was 1:6, the reaction time was 1.5 hours, and 1%(v/v) was catalyzed by 98% sulfuric acid. The results showed that the less moisture content in kemiri sunan oil, the less free fatty acid content was present in the biodiesel from the esterification results. This shows that the less moisture content in kemiri sunan oil at the esterification stage, the higher the conversion of free fatty acids to methyl esters or biodiesel. The highest conversion of free fatty acids into biodiesel of 91.89% was achieved when esterification was carried out on kemiri sunan oil with the lowest moisture content, namely 0.15%.

“…The moisture content of the kemenyan fruit was measured by using a drying method. Each part of the fruit, particularly exocarp, mesocarp, endocarp and endosperm were dried for 24 h in an oven at 103C until constant weight [11]. The fruit parts were then crushed using a blender and filtered using a 60-mesh sieve for further analysis.…”

Styrax sumatrana or the kemenyan tree grows in North Sumatera, Indonesia, and its resin is commonly utilized by the local community. Other parts of kemenyan, such as barks and fruits contain valuable compounds that can be extracted to produce high-value bioproducts. This study examined the effect of different resin grades on the physical parameters and cinnamic acid content, delignification pre-treatment period of kemenyan barks with Phanerocahete chrysosporium on the amount of extracted saponin from the barks, and different fruit ripeness on the composition of the fruits. This study showed that grade IV, V and VI resin contain 21.78 to 24.89% cinnamic acid. The isolated cinnamic acid had a purity of 90.9 to 94.3%. Pre-treatments of kemenyan barks were able to degrade 15% of the lignin after 21 days of incubation with Phanerochaete chrysosporium. and increased the amount of extracted saponin up to 7.5-fold higher compared to the non-pre-treated barks. Ripe kemenyan fruits had a higher protein (4.27-10.23%) and crude fat (0.91-7.36%) content as compared to the unripe fruits. Fatty acid composition of the crude fat had been determined and primarily consists of linoleic acid (31.71-42.33%) and palmitic acid (30.44-30.82%) for both ripe and unripe fruits.
