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.

Abstract

Batu kapur merupakan bahan tambang yang ketersediaannya sangat melimpah di Indonesia terutama daerah Sumatera Barat. Batu kapur disintesis untuk pembuatan filler Precipitate Calcium Carbonat. Hasil penelitian yang telah dilakukan terhadap filler Precipitate Calcium Carbonat dari batu kapur berdasarkan hasil analisis X-RD, FTIR dan SEM-EDX, dapat disimpulkan bahwa senyawa hasil sintesis dari CaO batu kapur adalah Precipitate Calcium Carbonat dengan jenis kristal aragonit dan kalsit. Sementara uji BET menunjukan luas permukaan spesifik filler Precipitate Calcium Carbonat dengan nilai 7,315 m2/g. Permukaan Plastik ramah lingkungan dengan penambahan filler Precipitate Calcium Carbonat dikarakterisasi menggunakan AFM didapatkan nilai Rq 0,43 µm.

Abstract

The development of functional food is increasing. Meatball is one of popular food product that can be developed to become more functional by adding antioxidant. Meatballs are processed products from small round meat. The aim of this study was to obtain the best formula for meat ball production with high antioxidant and also have good organoleptic characteristics. The addition of Moringa leaves, celery,cup leaves panax, and lime leaves to the original formula of meat ball production were used as the treatments in this study. The results indicated that the addition of cup leaves panax could produce the functional meat ball with the highest antioxidant and best organoleptic characteristics 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 compare 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 company standards that levels of cellulose and lignin in two different fields are obtained according to the standards set by the company. So for the results of testing Acacia crassicarpa wood from wetlands have 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 n-hexane 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.
