AbstractProcessing of purple sweet potato (Ipomea batatas L.) into chips is a means to improve the economic value. Crispiness is considered as one essential quality parameter for chip products that must be pursued. The thickness of slices and concentration of sodium bicarbonate (NaHCO3) constitute crispiness defining factors. This research was aimed at conducting organoleptic evaluation on a variety of purple sweet potato slice thicknesses and post-frying sodium bicarbonate concentrations using Non-Numeric Multi Person-Multi Criteria Decision Making (MP-MCDM). Research results showed that the Non-Numeric MP-MCDM method had successfully determined decision of the best prioritized decision among different alternative treatments of the ingredient. The preferred decision according to respondent opinions on the basis of organoleptic evaluation including color, aroma, taste, texture and overall acceptance were products from the 3 g/L NaHCO3 concentration with 1 mm (KB) slice thickness and the 3 g/L NaHCO3 concentration with 2 mm (KE) slice thickness and respondents seemed to like (SK) those products.AbstrakPengolahan ubi jalar ungu (Ipomoea batatas L.) menjadi keripik merupakan salah satu cara untuk meningkatkan nilai ekonomi. Kerenyahan adalah salah satu parameter mutu penting bagi produk keripik yang harus diupayakan. Ketebalan irisan dan konsentrasi natrium bikarbonat (NaHCO3) merupakan faktor penentu kerenyahan. Penelitian ini bertujuan untuk melakukan penilaian organoleptik berbagai variasi ketebalan irisan ubi jalar ungu dan kosentrasi natrium bikarbonat pasca penggorengan dengan metode Non-Numeric Multi Person-Multi Criteria Decision Making (MP-MCDM).

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins
