Degenerative disease is a disease caused by a decrease in the condition of the human body. Degenerative diseases can be prevented with a healthy lifestyle, one of them is consuming foods with high fiber. One of the high-fiber foods that are being developed at this time is the porang tuber. Glucomannan, which is mostly contained in porang tubers, is a polysaccharide that is easily soluble in water and high in fiber. Besides containing glucomannan, porang tubers also contain lots of calcium oxalate which can cause irritation to the tongue and mouth when consuming it. Calcium oxalate levels can be lowered through immersion in acidic solution. Solution that can be used to reduce calcium oxalate levels in porang tubers is lime. Soaking time is one of the factors that affect the reduction of calcium oxalate levels. Porang tubers that have been immersed in 5% lime solution for 60 minutes showed the highest decrease, namely 31.79%. In addition, soaking at high temperatures can decrease calcium oxalate levels in porang tubers also. Porang tubers that have been immersed in a 5% lime solution at 60 ° C, the calcium oxalate level has decreased to 49.58%.

The aim of this study was to identify and determine the heavy metal content of lead (Pb) and cadmium (Cd) towards eyebrow pencil registered and not registered by the Food and Drug Supervisory Agency (BPOM). This research was conducted in several markets in Surabaya. Twelve eyebrow pencil items were investigated for lead (Pb)and cadmium (Cd). Simple reagents, included HCl, NaOH, KI, Na2S2O3 and NH4OH were used to identify the presence of these heavy metal first. The study results showed that samples of eyebrow pencil registered and unregistered by BPOM RI after being tested turned out to contain lead and cadmium in a range of 1.092-5,834 mg/kg and 0,054-0.243 mg/kg, respectively. The content is still within what is required based on the regulations of BPOM RI, < 20 mg/kg for lead content and < 5 mg/kg for cadmium content. In short, all the sample of eyebrow pencil contained lead (Pb) and cadmium(Cd)within what is required based on the regulations of BPOM RI.

UV solar radiation intensively caused damage to human skin. Purple sweet potato leaves (Ipomoea batatas (L.)) contain a high anthocyanin component which has a chromophore group with conjugated double bonds, thus absorbing electromagnetic radiation in UV and Visible wavelength, so it can be used as a natural source of sunscreen. The aim of this research was conducted to determine the SPF value of ethanolic extract of purple sweet potato leaves (Ipomoea batatas (L.)) Antin-3 variety from two different drying methods namely freeze-drying for 48 hours (EFD) and oven for 24 hours (EOV). The results of this study indicate that Antin-3 leaf extract (EFD) at a concentration (ppm) 900; 700; 500; 300; 100 respectively are SPF 30; 25; 17; 11 and 4, while (EOV) respectively are SPF 13; 10; 7; 4 and 1. Effectivity sunscreen represented as SPF values, above 15 were categorized as ultra protection; between 8 and 15 as maximal protection; between 6 and 8 as extra protection; between 2 and 4 as minimal protection. From the results of this study, it can be concluded that the method of freeze-drying even though it requires a longer time and costs more expensive than the oven method but provides protection for sunscreen 2.5 times higher.
