Abstract

The textile and textile products industry is one of the mainstay commodities of the manufacturing industry as well as a driving force for national economic development. Like any production process, the textile manufacturing process also produces waste or residual substances called textile waste. Likewise the impact of the activities of garment, tailor, fashion, apparel and convection, one of which is patchwork waste. If the patchwork waste is not handled properly, it will result in waste generation which will have an impact on pollution in the environment. Lack of tools that can treat textile waste, resulting in less optimal handling of textile waste. This research is trying to make a design of a cloth chopping machine that is used to crush the remains of large rags into small pieces of cloth. Thus the packaging of fabric waste is easier and more efficient, besides that it can also be used as raw material for other products so that it can reduce fabric waste that pollutes the environment. In developing the model and design of a textile waste chopping machine, this chopping machine will cut the patchwork which can be sized according to your wishes. It is hoped that the results of this research will contribute to the development, advancement and appropriate technology. The design of this textile fabric waste chopper will provide a practical solution and zero waste process in a textile and garment industry.

Abstract

Citrus that comes from Kuok is one of famous local comodity in Riau Province with limited production. To improve the production of citrus it can be done by serving the superior seed throught budding. Rootstock aged and shading levels give effect to the success of budding process. The aims of the study were to obtain the best shade level, suitable rootstock aged and the interaction of rootstock aged with shade level on budding success. This study was conducted on December 2018 to March 2019 at the Experimental Field, Faculty of Agriculture and Animals Science, Islam State University of Sultan Syarif Kasim Riau. This study used split plot design with two factors, shading levels (0%, 50%, 70%) and rootstock aged (4, 8, 12 month) with three replications. The parameters this measured in this study were growth percentage of buds, percentage of sprout, percentage of dormancy, bud burst time, length of buds and number of leaves. The results showed that shade level of 0% and the age of rootstock 4 months produced the best growth of citrus seedlings. There is interaction between the shade level 0% and rootstock aged 12 month to the growth of the budding citrus seedlings.

Abstract

Natural fibers from pineapple leaves (Ananas comosus L.) are a potential renewable resource, but their characteristics are highly dependent on their geographical origin. This study aimed to characterize the physico-mechanical properties and morphology of pineapple leaf fibers (PALF) sourced from local farmers in Kediri, East Java. Characterization was conducted at an accredited testing institution using SNI standards, covering fineness, bundle tenacity, and Scanning Electron Microscopy (SEM) observations. The results revealed that the fibers exhibited an average fineness of 33.7 dtex and a tenacity of 23.20 g/tex. Morphological analysis showed a course, multi-cellular, and dense fiber structure. Based on these findings, it is concluded that these PALF demonstrate greater potential for applications in technical textiles and as reinforcement in bio-composite materials rather than as a raw material for apparel yarn.
