Abstract

Limestone is a mineral which is very abundant in Indonesia, especially in West Sumatra. Limestone is synthesized for making Precipitate Calcium Carbonate as a filler in plastics. The results of studies conducted on Precipitate Calcium Carbonate fillers from limestone based on X-RD, FTIR and SEMEDX analysis results, it can be concluded that the compound synthesized from limestone CaO is Precipitate Calcium Carbonate with aragonite and calcite crystal types. While the BET test showed a specific surface area of Precipitate Calcium Carbonate with a value of 7.315 m2 / g. Environmentally friendly plastic surfaces with the addition of Precipitate Calcium Carbonate filler were characterized using AFM obtained Rq value of 0.43 µm.

Abstract

The development of functional food is increasing. Meatball is a popular food product that can be developed to be more functional by adding antioxidants. Meatballs are processed products from small round meat. This study aims to obtain the best formula for meatball production with high antioxidant content and good organoleptic characteristics. The addition of Moringa leaves, celery, panax cup leaves, and lime leaves to the original meatball production formula was used as a treatment in this study. The research method uses an exploratory method through laboratory experiments. The treatment used was the addition of Moringa leaves, celery, bowl, and lime leaves. Each treatment was added with a different main ingredient as much as 3.3% with 3 repetitions so that the results can be said to be valid. The results showed that the addition of panax cup leaves could produce functional meatballs with the best antioxidant and organoleptic properties among all treatments.

Abstract

The development of the pulp & paper industries in Indonesia increase every year. To support the development of industries in Indonesia in order to be able to compete with similar industries from abroad, it is very important to pay attention to the quality of the paper produced. One way to determine the quality of the pulp & paper is by knowing the chemical composition and area where the wood grows. Important chemical compositions that can support the strength of wood and paper quality include cellulose and lignin. Therefore, this study was conducted to the levels of cellulose and lignin contained in Acacia crassicarpa wood from wetlands and Acacia mangium from dry land which is processed into pulp & paper with good quality. Determination of cellulose and lignin content in wood was carried out using the gravimetric method. Test results on Acacia crassicarpa wood species from wetlands obtained cellulose content of 55.48% and lignin 24.13%, while in Acacia mangium wood from dry land obtained cellulose content of 51.46% and lignin 27.66%. According to The National Indonesian Standards that levels of cellulose in two different fields are obtained according to the standards. So for the results of testing Acacia crassicarpa wood from wetlands has the highest levels of cellulose with low levels of lignin.

Abstract

Antioxidant extracted from soursop leaves with solvent extraction and stirring methods. Ethanol, ethyl acetate, and n-hexane use as a solvent. Extraction temperature varied of 35 °, 45 °, 55 ° C. The highest yield obtained was 20.2% from the ethanol extraction at a temperature of 55 °C. Test result of antioxidant activity using DPPH method indicates that the ethyl acetate fraction has the highest activity with% RSA 81.10 followed by ethanol and nhexane fraction of 69.64% and 27.60%. GCMS analysis indicated that the ethyl acetate fraction has the most antioxidant compounds with 11 compounds followed by ethanol fraction and n-hexane which has 9 and 4 antioxidant compounds with the highest content is the tocopherol group.

Abstract

This study aims to determine the Acid Value (AV) and the Saponification Value (SV) of Wax ester for each reactor in section 110 and compare the values obtained with the PT X standard. The method used is alkalimetry to determine the acid value and acidimetry for the determination of the Saponification Value. The results obtained were Acid Value 0.92 ppm - 1.02 ppm which was following the PT X standard, max 1ppm. The Saponification Value the results obtained were 132 ppm - 142 ppm which was following the PT X standard, min 130 ppm. This indicates that the resulting wax ester can be used for the preparation of fatty alcohols in sections 111-113.
