Abstract

PT. X is one of the companies engaged in the Flavors and Fragrances. The role of employees as resources in work activities in the Warehouse Department is very important for the sustainability of work because almost all activities use human power, from receiving and storing, picking, packaging to loading, many still use human power and the most frequently done is the process of lifting and moving both raw materials and finished goods. The loads lifted are also diverse and in quite large quantities. Based on the results of interviews with operators, information was obtained that soreness in the waist, back and hands occurred as a result of poor work attitudes and heavy lifting loads. There are also psychological complaints experienced by the Warehouse Division due to the demands of work targets that are felt to be less relevant in each shift, causing stress and mental pressure that can affect performance and work results that are less than optimal. To determine the magnitude of the physical and mental workload of employees in the Warehouse Division, measurements were carried out using the hear rate reserve (%HR reserve) method and NASA-TLX (National Aeronautics and Space Administration Task Load Index) to see the physical and mental workload. From the measurement results, it is shown that the physical workload experienced is in the light and moderate categories ranging from 1% -43.5%, while for the mental load that has a high impact ranging from Weighted Workload (WWL).

Abstract

The use of ducks down to serve as a filler in recent years has increased. In 2015, in Canada, the well-known jacket Company Canada Goose, which uses down as a filler, became very popular, even in 2016 its sales in the US grew by 50%. But the use of down is opposed by many parties including animal welfare groups (animal welfare) who campaign “save the duck” because the use of down is considered to hurt animals. Down is taken or uprooted from living birds without being given painkillers. Some companies then implement policies to ensure that the down used does not come from raw materials that hurt poultry. However, concerns about this still arise, because consumers will not be able to ascertain whether the down-fill jacket used is from Fluff plucked from living birds or not. In previous research, Wonosobo fleece has a thermal conductivity value of 0.03 W/moK, while the thermal conductivity of poultry fleece ranges from 0.024 – 0.03 W / moK. This shows that this fleece fiber has the potential to be used as an alternative raw material for jacket filler. In addition, Wonosobo sheep fur also comes from environmentally friendly materials, the process of epilation is done without hurting the sheep itself, it is the process of epilation of sheep have a positive impact on sheep, such as eradicating fleas on sheep fur. Based on the down issue and the potential of Wonosobo fleece to be used as a jacket filler, it is necessary to innovate the manufacture of multilayer jacket material made from fleece.

Abstract

Abstract: Hygiene is essential in daily life, and soap is vital for effectively cleansing contaminants and bacteria from the skin. Recent innovations in soap-making, including the development of transparent soaps, aim to enhance both functionality and aesthetic appeal. This study explores the incorporation of eco-enzyme, derived from the fermentation of kitchen waste such as fruits, vegetables, sugar, and water, into transparent antibacterial soap. Eco-enzyme contains lipase, trypsin, and amylase, which are effective in inhibiting pathogenic bacteria. The adoption of eco-enzyme not only enhances the sustainability of soap production but also promotes the efficient use of organic waste. This research conducted a laboratory-based experimental investigation to evaluate the effectiveness of eco-enzyme in the production of transparent solid antibacterial soap using palm oil. The process involved several stages: preparation of raw materials, soap production, and subsequent analysis. The results demonstrated that the soap met SNI standards with water content ranging from 12% to 17%, a pH between 9.57 and 9.81, and free fatty acids ranging from 0.9% to 1.7%. The inhibition zone for Staphylococcus aureus was 7.81 mm, indicating a moderate antibacterial effect. These findings suggest that eco-enzyme provides a bacteriostatic effect, inhibiting bacterial growth without necessarily killing the bacteria, and highlight its potential for developing sustainable and effective antibacterial products. Keywords: antibacterial soap, eco-enzyme, Staphylococcus aureus.

Abstract

Abstract: There is a lot of waste on earth in the form of textile waste in the form of fabrics either from textile waste fabrics produced by convection or from used clothing. This study aims to utilize the textile waste fabric as raw material for making activated carbon. To determine the content of activated carbon from textile fabric waste, it would be better if the fabric is grouped according to its classification whether it includes fibers derived from cellulose fabrics or synthetic fabrics. This test is done by combustion test, dissolution test and microscope test. To calculate the content of activated carbon produced by using NaOH and NaCl activator substances of various concentrations of 8%, 10%, and 12% for 24 hours. Carbonization process temperature 480 ˚C for 5 minutes. Activated carbon analysis calculates: water value, ash value, iodine number analysis, volatile matter value, fixed carbon, and SEM test. The results of the research of activated carbon that meets the qualification standards of SNI activated carbon 06-3730-1995 are water value and ash value, while the value of iodine number, volatile matter, and fixed carbon has not met the standards.

Abstract

The government is currently trying to increase the added value of product, especially products whose raw material come from within the country. One way to increase added value is by downstreaming commodities. Petroleum is one of the commodities that will be downstream from the upstream to downstream sector. There is limited petroleum in Indonesia, so it needs to be utilized as best as possible. So that the added value of petroleum can be returned with greater value. From the results of the study, there are five industrial sectors that can be developed by government to downstream petroleum commodities, namely liquid parafin, phenol, cumene, caprolacton and polycarbonate

Abstract

Based on the mandate of Law Number 33 of 2014 concerning guarantees for halal products, that all products circulating in the market including goods used or utilized by the public must be halal, one of which is textile and clothing products. Currently, not many textile and clothing products are halal-certified. Whereas textile and clothing products have great potential to develop their business in supporting the strengthening of the value chain in the halal industry. Halal traceability is one of the halal requirements that must be met in the manufacture of halal products, this is stated in the Halal Product Guarantee (JPH) HAS 23000. Halal traceability is also an important factor in maintaining halal integrity. There are various methods used in developing a halal traceability system. One of them is the IDEF0 method. The IDEF0 method can be used in determining plans to capture traceability information needed by internals. In addition, IDEF0's simple notation construction consisting of input, control, output, mechanism (ICOM) becomes the main strength as a communication tool that is easily understood by everyone. Therefore, this study develops a model of a halal traceability system based on critical activities that can change the halal status of a product with the IDEF0 method in the Small Medium Enterprises (SMEs) of Muslim women's clothing. Based on the results of the study, there are six critical activities that affect the halal status of products during the production process, namely, material purchasing activities, material receiving and storage activities, supply to production activities, production activities, finished product storage activities, and outgoing transportation activities.
