Abstract

The textile and textile product (TPT) industry is one of the mainstay commodities that drive the economy in Indonesia. Export market opportunities are very open for this commodity, but the current problem is the waste generated from this industry. PT.Vonex is a textile industry with spinning and dyeing products. Textile liquid waste produced has a very concentrated color characteristic and when the dye enters the waters it can cover the surface of the water body so as to block sunlight from entering the waters. Textile wastewater treatment with the sono-Fenton method as DCA (Decolorizing Agent) can be used as an alternative choice in overcoming these problems. In this study, an analysis of the reduction of the dye was carried out by using variations in the concentration of Fenton's reagent and the length of sonication time. The variations in the concentration of Fenton's reagent used were 1:1, 2:1, 4:1, and 6:1 while the sonication time used variations of 10, 30, 60 and 90 minutes. The test results show that the use of Fenton's reagent assisted by ultrasonic waves (sonication) in textile wastewater treatment can reduce the levels of color values, pH, COD, BOD, and TSS. The results showed that the variation of Fenton reagent concentration 1:1 with a sonication time of 30 minutes was the optimum condition with a percentage decrease in color value of 99.61%, a decrease in pH value of 68.94%, a decrease in COD value of 90.64%, a decrease in BOD levels by 97.48%, and a decrease in TSS levels by 91.28%.

Abstract

Handmade art encompasses various forms of handicraft art created by humans, including knitting. Knitting is a needlework activity that utilizes thread and hook needles. It encompasses different techniques such as embroidery, weaving, crocheting, and knitting itself. Additional activities like lacework, quilting, embroidery, needlepoint, and rugs are also considered part of the knitting realm. Although knitting and crochet are sometimes used interchangeably, they have distinct meanings. Crochet can be created using either manual or mechanical methods, employing a special hook needle to create desired shapes by hooking the thread under the previous loops. Crochet work is known for its textured appearance, with the texture varying depending on the stitches used. Examples of crochet stitches include chains, single crochet, half double crochet, double crochet, treble crochet, double trebles, slip stitch, blocks, picots, cross stitch, clusters, knots stitch, and popcorn stitch.

Abstract

Sea water intrusion is a process where sea water is mixed with underground water around the coast, causing the ground water to become salty because it is contaminated by sea water which is rich in salt. Sea air that enters the ground causes the air to become unfit for consumption and causes the land to become unproductive for planting. People in the Pakis Jaya area, Karawang face difficulties, especially regarding land use for agricultural activities. This is because the land used for cultivating plants is saline soil with a high salt content. Phytoremediation is a method used to clean air or soil contaminated with pollutants, by using the ability of plants to absorb these substances. Cynodon Dactylon and lolium Perenne Brightstar plants are a type of grass that can be used to reduce high salt levels in the soil because these plants are able to live in places with high salinity and also have the ability to reduce salinity by absorbing chloride ions in it. The methods used in this research consisted of: Sampling Process, Plant Acclimatization Stage, Salinity Concentration Test before and after planting grass in Soil Media. The test results showed that the salt content in the soil before planting was 19.20 dS/m and after planting it was 0.02-0.03 dS/M.
