Abstract

Purpose

This paper aims to prevent cotton textiles from fungi damage using eco-friendly aloe vera leaf extract, which was applied at a minimum amount, and cost-effective material.

Design/methodology/approach

Batch extraction method using methanol solvent; phytochemical analysis was investigated and three-level factorial design of experiment and analysis of variance (ANOVA) was used for the optimization of 27 test runs. The finish was applied by pad-dry-cue at distinct concentrations, and the chemical property after treatment was studied. Colorfastness and coordinates are analyzed. Cotton fabrics were cultured with Fusarium oxysporum fungi and the anti-fungal property was examined and reported according to AATCC 30–2004 standard.

Findings

The maximum yield of extract was at an optimum volume of 200 ml, 65 °C for 120 min. The effective antifungal fabric was achieved with minimum concentrations. There was significant strength loss in warp and weft direction. The treatment results in yellow-colored cotton fabric with fastness grade 3. The antifungal effect is durable until fifteen washes as the tensile strength losses were less than 1%.

Research limitations/implications

The findings of this work were based on samples considered in the laboratory. However, it can be reproducible at the factory production scale the treatment has the potential of yielding yellow dyed cotton fabric with multifunctional finishing.

Practical implications

The treated fabric is against Fusarium oxysporum Fungi which is one of the vital antimicrobial properties of textile apparel products for various areas of application.

Social implications

The natural extract material applied to a textile material is eco-friendly effective against microbes of cotton seeds during cultivation and apparel end-uses.

Originality/value

The work application of fungi resistance on cotton fabric using aloe vera active component was original; this work provides extraction of the active agent from aloe vera leaf, which is optimized statically and successfully applied for anti-fungal activity on cotton fabric.

Abstract

Purpose

The purpose of this paper is to determine the effect of adding Aloe vera powder (AVP) in the production of mahewu with the aim of determining its shelf-life and sensory qualities.

Design/methodology/approach

Mahewu was produced at home (Sample B) and in the laboratory (Sample C) using a standard home-made procedure with the addition of AVP. A control mahewu (Sample A) was produced without AVP. Shelf-life was determined by following the chemical, microbiological, physical properties at 36 ± 2 °C for 60 days and the sensory properties of the products were also evaluated.

Findings

Physicochemical analysis revealed decreases in pH ranging between 3.3 and 2.4 from day 15–60 days of storage in all three samples. There was a significant increase (p < 0.05) in titratable acidity (0.2–1.8%) of all mahewu samples during storage. Total soluble solids were different amongst the samples from day 15 to day 60. The colour of the products was significantly different (p = 0.05) with respect to L*, a* and b* throughout the storage period. Microbiological results revealed an increase in coliforms bacteria, lactic acid bacteria, and yeast during storage. Sensory analysis showed that the control mahewu was more preferred than AVP added mahewu.

Practical implications

The study may help small-scale brewers to increase the shelf-life of mahewu.

Originality/value

Results of this study showed that the addition of AVP extended shelf-life of mahewu up to 15 days at 36 ± 2 °C.

Abstract

Business planning project with experiential approach have been implemented in beverage processing technology course, as a part of entrepreneurship teaching in undergraduate food technology study program. Seventy one students were divided into 6 groups and each group designed a business plan of beverage production. The business plans (production of RosBerry juice, Alang‐alang jelly drink, Luo Tung Kua healthy drink, Aloe vera juice, Soycorn milk and Bumble bee) were realized by production each product in pilot plant and selling the products in campus area. Five groups succeed to realize their business plans and get profit varies from 11.67 per cent to 58.29 per cent, but one group (production of Bumble bee) suffered losses of 28.63 per cent. About 84 per cent of students possess sufficient self‐confidence to success as an entrepreneur. Significant increasing of self‐confidence to success in business planning and marketing occurred. However, declining of self‐confidence also occurred especially in financing and managerial skill aspects. It is needed to improve self‐confidence in financing and managerial skill aspects.

Abstract

Purpose

The main aim of this study was to improve current efficiency and to obtain thicker coatings via aluminum oxide (Al2O3) addition to the chromium (Cr) (III) bath.

Design/methodology/approach

Pure Cr and nanocomposite Cr–Al2O3 coatings were electrodeposited from Cr (III) bath onto cathode copper substrates by conventional method. Dependence of current efficiency to current density, Al2O3 content and particle size were investigated.

Findings

Current efficiency increased with Al2O3 amount and decreased with Al2O3 particle size. Maximum current efficiency was achieved at 25 A/dm2 for pure Cr and 30 A/dm2 for composite coatings. Al2O3 bath content, current density and stirring rate increased the coating Al2O3 weight per cent significantly. Addition of Al3+ bath composition inhibited nanoparticle agglomeration, increasing film homogeneity. Cr–Al2O3 nanocomposites showed higher microhardness and better corrosion resistance than pure Cr layer.

Originality/value

Cr (III) is not as toxic and as carcinogenic as Cr (VI) which is widely used for Cr electroplating these days. Low current efficiency and poor product quality are, however, major drawbacks of the former. This paper describes significant improvements obtainable by addition of Al2O3 nanoparticles to the Cr (III) bath for increasing the microhardness, the corrosion resistance and the current efficiency of the deposition.

Abstract

Purpose

The study aimed at developing the bioremediation model of Lapindo mud through multisymbiotic organism.

Design/methodology/approach

The research was conducted using completely randomized design. The model plants chosen in this research were soybean. The interaction pattern during the treatment was used to develop the bioremediation model based on the parameters.

Findings

The results showed that there was an effect of the type of organism on the parameters, namely: the growth of plant (biomass, height, length of root, and number of leaves), the biomass of root nodules, the percentage of mycorrhizal infection, the content of water, nitrogen, phosphorus, and total petroleum hydrocarbons (TPHs). There was a pattern of multisymbiotic interaction between each organism and roles of each symbiont in that interaction. Therefore, the plants were capable of surviving in the environment of Sidoarjo Lapindo mud. This pattern can be named as the bioremediation model proposed, which is the analogy of tripartite symbiosis between plants, mycorrhizae, and Rhizobium but also adding plant growth bacteria such as phosphate-solubilizing bacteria and hydrocarbon degradation bacteria. The implementation of this model can be used to treat oil-contaminated soil in order to be used as a plant growth medium.

Originality/value

Phytoremediation is a new and promising approach to remove contaminants in the environment but using plants alone for remediation confronts many limitations. Therefore, the application of plant-growth-promoting rhizobia (PGPR) has been extended to remediate contaminated soils in association with plants (Zhuang et al., 2007). The development of the model will use the analogy of tripartite symbiosis between plants, mycorrhizae, and Rhizobium. The developed model will be based on the interaction pattern on each parameters obtained. Bioremediation is chosen because it is considered an effective technique to transform toxic components into less toxic products without disrupting the surrounding environment. Besides, bioremediation is cheaper and environment-friendly because it utilizes microorganisms to clean pollutants from the environment (Nugroho, 2006).
