“…The husk ash used is varied in size using a sieve sieve (100, 80, and 60) mesh to homogenize and remove impurities [15]. The husk ash that passes through the sieve is ovened at a temperature of 120 C ̊ for 2 hours with the aim of reducing the water content in it so that it does not affect the KA in the VCO which is then cooled in a desiccator [7].…”

Virgin Coconut Oil (VCO) is an oil produced using low temperatures. Efforts to maintain and improve the quality of VCO with papain enzymatic manufacturing method followed by the provision of husk ash adsorbent. The use of papain enzyme as much as 1.5% w/v with an incubation temperature of 40°C 24 hours was effective in reducing acid numbers. The husk ash adsorbent which was treated in an oven at 120°C 2 hours was effective in improving the color quality of the VCO. Variations of husk ash were adsorbent size (60, 80, and 100) mesh and mass (15, 20, and 25) grams. The sample that has been mixed with adsorbent is stirred with a magnetic stirrer at 300 rpm 1 hour then separated by centrifuge at 1000 rpm 1 hour and ends with VCO filtering with filter paper to separate the remaining adsorbent from the oil. Samples were tested for acid number and free fatty acid content. The results show that the smaller the size of the adsorbent and the more the amount added gives a positive effect on decreasing the acid number and free fatty acid content. Production of VCO has low environmental impact because it uses low energy.

Bunga Eceng gondok (Eichhornia crassipes) mengandung fenol, flavonoid, alkaloid, tannin, terpenoid, sterol dan glikosida yang mempunyai aktivitas antibakteri dan berpotensi diformulasi menjadi sabun antisptik. Minyak jelantah yang telah dimurnikan menggunakan kulit pisang kepok berpotensi sebagai bahan pembuatan sabun. Tujuan untuk mengetahui metode pengolahan minyak jelantah, formulasi dan uji aktivitas antimikroba sediaan sabun antiseptik ekstrak air bunga eceng gondok dengan memanfaatakan minyak jelantah. Metode yaitu quasi eksperimen laboratorium yakni sabun antiseptic diformulasi berdasarkan tiga konsentrasi infusa bunga eceng gondok, Formula A (10%); B (15%) dan C (20%). Evaluasi sediaan berupa fisik dan kimia, uji iritasi dan uji aktivitas antibakteri. Hasil pemurnian minyak jelantah yaitu minyak yang jernih dan tidak kental. Ekstrak air bunga eceng gondok dapat diformulasi menjadi sabun antiseptik dengan tinggi busa rata-rata 1,5 cm, daya bersih pada kriteria 3 (kesat), pH pada rentang 9-10, kadar air >15%, kadar alkali bebas 0,6-1,3 % dan tidak menunjukkan iritasi. Sabun antiseptik ekstrak air bunga eceng gondok memiliki aktivitas antibakteri terhadap E.coli kategori kuat berdasarkan diameter hambatannya, yakni Formula A (19,17 mm), B (20,01 mm) dan C (20,13 mm). Kesimpulannya ekstrak air bunga eceng gondok dan minyak jelantah dapat menjadi alternative pemanfaatan limbah menjadi sediaan sabun antiseptik yang memiliki aktivitas antimikroba.

Lemuru fish (Sardinella lemuru) is rich in omega-3 so it is widely used as raw material for fisheries production such as fish canning which produces by-products in the form of crude fish oil which needs to be purified by adding adsorbents so that it becomes pure fish oil. The adsorbent that can be used in the purification of fish oil is activated charcoal. Fish oil can be used as raw material for making added value products such as margarine. The aim of this study is to analyse the characteristics of margarine as a value-added product made from fish oil. Research shows that purification with activated charcoal produces fish oil with %FFA and PV that are in accordance with IFOS. Fish oil margarine in this study showed organoleptic value of colour 7.4 and aroma 7.07, emulsion stability 100%, %FFA content 0.28 ± 0.08, PV 1.6 ± 0.173, and higher 0.39% EPA and 2.58% DHA content compared to commercial margarine. In previous study showed margarin from sardine fish oil contains 19.5% EPA and 10.5% DHA which is also not found in commercial margarine from palm oil. The difference in EPA and DHA content between this study and previous study may be due to the fact that the fish oil in this study was obtained from by-products of canning processing with high temperatures which may cause a decrease in fatty acid levels due to protein denaturation.
