Abstract

Membrane is a polymer layer that can be used in the process adsorbsi metal ions. Membrane can be synthesized from silica dust bagasse that termodifikasi kitosan. The purpose of this research is to know the impact of the addition of a variety of silicate on the characteristics of the membrane silika-kitosan the bagasse to the adsorpsi metal ions Pb. The content of silica in the bagasse to 73, 80 %. Membrane kitosan-silika be made with different variations of the composition of which is 1 : 1 ; 1 : 1, 5 ; 1 : 2 ; 1 : 2, 5 and 1 : 3 and the ability of the adsorpsi the metal Pb in a row of 41 %, 43, 76 %, 54, 88 %, 38, 36 % and 39, 6 %.. The application of membrane to the process adsorpsi metal ions Pb by membrane said with a ratio of 1 : 2 to concentrate Pb the beginning of the 50 parts per million. The use of membrane to the process readsorpsi to do with how to choose a membrane that has the adsorpsi of the membrane with a ratio of 1:2 be able to absorb metal Pb of 1 ppm. Membrane that has been used can be used with traffic readsorpsi, 2 % in the membrane of every 1 : 2.

Abstract

Indonesia as the third largest grain producer in the world produces large amounts of bran. High contain Free Fatty Acid (FFA) in rice bran oil causes it can be converted into the fatty acid ethyl esters (biodiesel) by esterification and transesterification methods. The rice bran oil was obtained by rice bran extraction using n-hexane. The esterification process was catalyzed by HCl. In this study, the transesterification process to convert triglycerides into ethyl esters (biodiesel) was conducted by the addition of KOH as a neutralizer and a catalyst Oil and ethanol by ratio 1:6 using 0,5% KOH  as catalysator were reacted by utilizing 47 kHz ultrasonic wave for 45, 60 and 75 minutes. Biodiesel conversion value obtained were 49,23%; 70,55% and 52,04% respectively. Biodiesel product spectrum was analyzed using FTIR and GCMS instrument. The density, viscosity and flash point is also measured.  FTIR analysis on all variations give similar data spectrum, where the ethyl ester products are characterized by typical bands at specific frequencies such as -C=O; -C-C; -C-H (sp3) and = C-H (sp2) stretch. Based on the data from GCMS spectrum, the product components are ethyl palmitate, ethyl linoleate, ethyl stearate and ethyl oleate.

Abstract

Edible film is a thin layer that serve as the packaging or upholstery as well as food that can be eaten with a product. It is packaged and can be degraded by nature. Potato starch can be used as raw material in manufacturing edible film, in which the addition of glycerol is needed as a plasticizer that function to improve the elasticity of the edible film. The goal of the research is to know the influence of glycerol concentration variation against the characteristics of edible film of starch potatoes (Solanum tuberosum L.) the parameters examined in this study i.e the physical test that includes a test of strong thickness, tensile test and present enlargement, test the solubility and organoleptic. To help figure out the data obtained in the real effect or not, is done using the SPSS Analysis Variant 1 direction or one-way ANOVA. Characteristics of edible film from potato starch with addition of glycerol with a concentration of 20%, 30% and 40% (v/v) to the value of the thickness of consecutive 0,058 mm, 0,062 mm and 0,071mm. The value of the tensile strengh i.e 0,75 N/mm2, 0,69 N/mm2 and 0,35 N/mm2. The value obtained by elongation percent 4,96%, 9,04% and 9,51% where as the value of solubility is obtained that is 19%, 21,4% and 34,6%. Application of edible films from potato starch as the packaging on candy jelly can be acceptedas alternative packaging material for food.

Abstract

The physicochemical propertis of forest honey (Apis dorsata) become one of the supporting qualities of honey. Good honey can be viewed from the quality of honey which refers to the Indonesian National Standard (SNI). Therefore, this research aims to determine the physicochemical properties of forest honey from the village of Bonto Manurung, Maros district, Tompobulu village, Pangkep district and Paranglompoa village, Gowa district in accordance with the SNI. The results showed that the best physicochemical properties of honey were from the village of Bonto Manurung, Gowa district which had a moisture content of 19.19 %b/b, ash content of 0.045 %b/b, viscosity of 14.82 poise , acidity is 42.43 mL N NaOH/kg, reducing sugar is 69 %b/b and HMF levels are 2.99 mg/kg. As for the analysis of metallic impurities, all samples examined forest honey is not contaminated by metals arsenic (As), cadmium (Cd) and lead (Pb).

Abstract

This study aims to analyze the physical and chemical properties of soil from paddy fields, garden lands and city area also determine the soil inhibitory test of dog saliva bacteria. The results showed that these three soil types have different physical chemical properties and have different inhibitory zones against dog saliva bacteria. The physical chemistry of soil from paddy fields, garden lands and city area (0 cm) are as follows: for color; dark chocolate; grayish brown; and blackish ash, for texture: clay; clay; and sandy clay, for moisture content: 7.14; 6.53; 2.13. for pH close to neutral around 6.52-7.03; Total N is low (0.08-0.23); organic C compounds are classified as moderate; nutrient content of Ca/Mg is classified as moderate (9.55 /1.70 - 14.89/2.22); cation exchange capacity is classified as high (25.32-29.03) in paddy fields and gardens and compounds. The inhibitory zone of the highest dog saliva bacteria is in garden soil (3.7 cm), then paddy soil (2.86 cm) and land in the city area (1.6 cm).
