Increasing the quality of virgin coconut oil (vco) using activated carbon adsorbent from candlenut shell (Aleurites mollucana)

Abstract

Virgin Coconut Oil (VCO) is one of the product from coconuts. VCO has many benefits in health and industry. One method of making the VCO is often used today is the fermentation. Today many domestic industries produce virgin coconut oil (VCO) but in fact, the industry has not been all good in terms of quality. The use of activated carbon from candlenut shells as an adsorbent to increase the quality of VCO has studied. The parameters tested were water content, free fatty acid, and peroxide. The results showed a decline in water levels from 0.1655% to 0.0597%, peroxide number decrease from 0.1991% to 0.0991%, and the free fatty acid content of 0.4186% to 0.366%.

Short Communication: The emergence and rise of indigenous thermophilic bacteria exploration from hot springs in Indonesia

“…Ijen, Solok, Sulili, Bora, and Jailolo are hot springs with different characteristics, and located far from one another on different islands. However, all of these surprisingly demonstrate similar isolates from genus Bacillus (Kusumadjaja et al 2010;Harnentis et al 2013;Hafsan et al 2017;Ifandi and Alwi 2018;Arfah et al 2020). Therefore, the documentation process is expected to be moved from the genus to species level, for the provision of better details.…”

“…This approach was first performed by Huber et al in 1996), before the whole-genome sequencing method by Cho et al in 2000. The conventional method is known to be the oldest, and also has some limitations, resulting from the inadequate number of culturable microbes in the desired environment (Chaudhary et al 2019). The current papers with reports on this technique were mainly based on samples sourced from Mount Pancar, West Java, and consequently used for hydrogen production, amylolytic bacteria isolated from Jailolo Bay, North Maluku, and amylase from Pulu hot spring, Sulawesi (Arfah et al 2020;Gazali et al 2020;Satrimafitrah et al 2020). These indicate the reasons for a high percentage (38%) application as an exploration method.…”

Utilization Of Activated Charcoal From Nutmeg Shell Waste As An Adsorbent To Improve The Quality Of Virgin Coconut Oil (VCO) Fermentation Method

“…Peningkatan kualitas VCO dapat dilakukan dengan menggunakan arang aktif. Arang aktif yang telah digunakan untuk meningkatkan kualitas VCO adalah arang aktif dari tempurung kemiri (Aluerites mollucana) (Parlindungan et al, 2020). Selain kulit kemiri yang bisa dijadikan arang aktif, ada penelitian yang menyatakan bahwa tempurung pala juga dapat dijadikan arang aktif dan memiliki kualitas sangat baik sebagai absorben (Hitijahubessy, 2019).…”
