Abstract

Mount Agung with an altitude of 3.142 meters above sea level is located in Karangasem. This mountain is one of the active volcanoes in Indonesia. Some dangerous impacts caused by the eruption of Mount Agung are acid rain, earthquakes, lava/lava flow, landslides/mudflow, smoke from lava, pyroclastic, rain of volcanic ash, and rocks and also volcanic gas. One of them which is Rain of volcanic ash can cause blisters on the skin and eyes as well as respiratory irritation. For long-term effects can cause silicosis (lung disease resulting from dust) and chronic lung disease. This study was conducted to determine the Mount Agung volcanic ash eruption effect on the results of SPM concentration measurements at the Jembrana Climatology Station using comparative data and sample data obtained from SPM, VONA concentration measurement data, and the HYSPLIT Volcanic Ash (NOAA) models.

Abstract

One of the problems that related to quality and often occurs in the sewing process at CV Batara Apparel is that there are frequent thread break problems. Termination problems that occur are caused by an error during the thread installation process that does not pass through the needle bar hole and the thread is directly passed through the needle. This results in defects in stitches such as broken stitches. In order to solve the thread break problem caused by an error during the thread installation process that does not pass through the needle bar hole, it can be overcome by implementing SOP (Standard Operational Procedure) on proper and correct machine usage procedures, briefing supervisors with the production manager so that the problems occurs when production takes place can be handled properly. In addition, the implementation of regular maintenance schedules can also solve the thread break problems that occur. Keywords: thread break, loose stitches, quality control, SOP

Abstract

The process of applying starch to the warp yarn in order to increase the weaving power of the warp yarn in the presence of a starch layer, is expected to increase the strength of the yarn and reduce the yarn hairs. One of the factors that influence the sizing process is the amount of pressure in the squeezing roll. In this process, the sizing machine uses a double size box and each size box has 2 (two) squeezing rolls. The material used is Combed Ne 40 yarn with construction ,which is the amount of tetal or the density of the yarn with the construction included in the tetal of the dense warp yarn. The method used by comparing the pressure of squeezing roll process 1 and process 2. In the first process, the squeezing roll 1 is set at 3 kN and squeezing roll 2 is 3.5 kN, while in the second sizing process, the squeezing roll 1 is set at 4 kN and squeezing roll 2 for 5kN. After the experimental process was carried out, the starch warp yarn strength was obtained which was higher, namely 351.93gr and compared to process 2 which was 345.84 gr. The higher from the strength of the starchy yarn, can make it better for weaving process.

Abstract

Permanent press by using resin will increase the resistance of the desired material properties. The refinement process to obtain permanent fold properties in polyester fibers is obtained by forming a polymer resin layer on the surface of the fabric. The more resin used, the less the ability of the fabric to come back from the crease, so the permanent crease finish will be more permanent. However, with more and more resin polymerizing on the surface, the fabric will be stiffer and can reduce the tensile strength of the fiber, the occurrence of the resin polymerization process is influenced by the temperature of the preserved heating when the temperature is less then the resin is not formed perfectly or if the temperature is too high it can cause damage to the fiber. This test was carried out on 100% polyester fabric with variations in the concentration of melamine formaldehyde resin 40 g/l, 50 g/l, 60 g/l, 70 g/l and variations in the curing temperature of 1600C, 1700C, 1800C, 1900C. Tests carried out include re-testing of the folds and tensile strength of the fabric. The results showed that the optimum conditions achieved in this experiment were at a concentration of melamine formaldehyde resin of 60 g/l with a preserved heating temperature of 1700C, a low folding angle value of 740 was obtained with a tensile strength value that above the minimal standards, namely the warp 75.7 Kg and weft 22.7 Kg.
