Abstract

Continuous and repeated use of cooking oil at high temperatures accompanied by air and water contact can result in a hydrolysis reaction. The quality of the oil can be determined by carrying out the procedure for determining the free fatty acid content (FFA). Used cooking oil can be purified using an adsorbent/absorbent. Sugarcane bagasse and corn cobs have been widely used as adsorbents, but there has been no study comparing the increase in oil quality with these two adsorbents. This study aims to compare the color of the used cooking oil immersion with bagasse adsorbent and corncob charcoal adsorbent and determine the value of FFA levels of used cooking oil before and after soaking with bagasse adsorbent and corncob charcoal arsoben. The method used is fatty acid adsorption method and alkalimetric titration. From the observations, it was found that the color of the used cooking oil was fading after soaking with 3 types of adsorbents. The color of the immersion with a mixture of 1:1 adsorbent corncob charcoal and bagasse has the highest brightness level. FFA levels of used cooking oil after soaking also decreased from 0.207% to 0.141%; 0.132 %; and 0.094 %. The FFA content of used cooking oil by immersion in a 1:1 mixture of corn cob charcoal and bagasse was the lowest, which means the oil has the highest quality. It can be concluded that a mixture of 1:1 adsorbent of bagasse and corncob charcoal is the best adsorbent.

Abstract

Infectious skin diseases in West Nusa Tenggara Province are listed as one of the ten most widespread diseases. Treatment for skin disorders can involve both medical and non-medical approaches. Ethnomedicine offers a way to investigate the applications of medicinal plants and can serve as a first step towards the discovery of new drugs. The purpose of this article is to explore the types of plants used in traditional skin disease treatments. The research results found that plants that can be used for skin disease treatment are predominantly betel, galangal, and members of the Zingiberaceae family. Then, other plants are tobacco, nettle (Toxicodendron radicans), brotowali (Tinospora arisp), kanangas (Ximenia sp.), pomegranate (Punica granatum), grepek (Erythrina sp.), ciplukan (Physalis angulate), water lettuce (Nasturtium microphyllum), lily (Chlorophytum comosum), kesum (Polygonum minus), gelinggang (Cassia alata), cogongrass (Imperata cylindrica), neem (Azadirachta indica), papaya (Carica papaya), mahkota dewa (Phaleria macrocarpa), teki (Cyperus rotundus), lime (Citrus aurantiifolia) and kedondong pagar (Lannea coromandelica), jackfruit (Artocarpus heterophyllus), rice (Oryza sativa), tamarind (Tamarindus indica), coconut milk (Lannea coromandelica), lamtoro (Leucaena leucocephala), sambiloto (Andrographis paniculata), frangipani (Plumeria alba), iodine (Jatropha multifida), and binahong (Anredera cordifolia). The use of medicinal plants by various communities significantly impacts public health and ecosystems. Utilizing these plants can reduce dependence on synthetic drugs and mitigate negative impacts on the environment. Ethnomedicine can further enhance the understanding and appropriate and safe application of medicinal plants, while supporting the preservation of community customs and heritage.
