Abstract

Before detergent was commonly used, a natural cleanser which function is to help people to clean several things in their houses was Lerak berry (Sapindus Rarak DC).  This berry contains saponins (28%) which can be used as the ingredient for shampoo, soap, and other kind of cleaning agents. Dilutting Lerak juice into soap base will produce liquid washing soap which can be an alternative to reduce the use of detergents. This study aims at finding the best treatment, balance ratio of Lerak juice (2:1; 3:2; 1:1; 2:3), and diluting method for the soap base (heating and non-heating) to be used for producing liquid washing soaps with the best characteristic. This study uses two-factor randomized block design method which later be analyzed using ANOVA. Organoleptic testing of the hedonic quality to the color, scent, foam quantity, cleaning-power, the after-effects impression, and the general assessment of the liquid washing soaps results a 2:1 Lerak juice balance ratio with heating method is found to be the best treatment for diluting method. The balance ratio affects the consistency and viscosity which also affects the density, pH, and water holding capacity, but does not affect the foam’s stability.

Abstract

Cooked rice (nasi liwet) is a typical rice dish of Java Island which is cooked using spices so that it has a unique taste and aroma. Making nasi liwet takes a long time, so this dish is only served at certain times. Therefore, a fast rice processing technique is needed but still has a distinctive taste and aroma. The purpose of this study is to analyze the physicochemical analysis of instant liwet rice based on the concentration and soaking time of sodium citrate. The physicochemical analysis tested were rehydration time, volume expansion, bulk density, texture, yield, ash content, and water content. The study was conducted by soaking sodium citrate (0, 2, 5, and 8% w/v) and soaking time (2, 4, and 6 hours) on rice. The results showed that the fastest rehydration time for instant nasi liwet was 4.55 minutes. The range of observation parameters such as expansion volume is 66.26-91.24%; bulk density is 0.413-0.581 g/ml; the texture is 431-1496 g/mm; yield is 89.64-92.26%; ash content is 4.11-4.45% and water content is 5.83-7.03%wb. Variations in sodium citrate concentration and immersion time increased the swelling volume and ash content, while water content, bulk density, texture, and yield tended to decrease. The best treatment based on the multiple attribute Zeleny method was immersion of 5% sodium citrate for 4 hours of immersion. Keywords: Immersion Time, Instant Rice, Nasi Liwet, Physicochemical, Sodium Citrate
