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 process of shipping products in the textile industry is essential as it determines the effectiveness of the business. However, non-ideal shipping can result in damage to the shipped products. Therefore, this study aims to develop a mathematical model to optimize the shipping process by assessing the textile product damage rate against environmental parameters such as humidity and temperature and shipping parameters such as shipping duration. The model developed using the Response Surface Methodology (RSM) statistical approach is based on linear and nonlinear models. The results showed that the linear model had a better coefficient of determination as a model validation parameter, with a coefficient of determination of 0.83. This value shows the effectiveness of optimizing the shipping process as a monitoring effort to determine the damage to textile products against several parameters that affect it. The results of this study have implications for the field of textile science, especially regarding the dynamics of distribution or logistics, as well as the application of mathematical applications in the textile field. In addition, the practical implications of this research are expected to be used as a monitoring effort for the textile industry to determine the impact of environmental parameters and shipping duration on the products they ship.

Abstract

Pencapan dengan zat warna pigmen dapat digunakan pada semua jenis serat. Zat warna pigmen tidak mempunyai afinitas terhadap serat, maka fiksasinya ke dalam serat diperlukan bantuan zat pengikat yaitu binder. Kekuatan ikatan antara zat warna pigmen dengan serat tergantung pada daya ikat dari binder yang digunakan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi binder terhadap ketahanan luntur warna dan handfeel kain poliester yang dicap dengan zat warna pigmen. Variasi konsentrasi binder yang digunakan adalah 7%, 10%, dan 20%. Pada  penelitian ini akan mengevaluasi dari sifat kelunturan warnanya dan daya handfeel dari hasil pencapan tersebut. Hasil penelitian menunjukkan bahwa konsentrasi binder memiliki pengaruh yang signifikan terhadap ketahanan luntur warna dan handfeel terhadap hasil pencapan kain poliester dengan zat warna pigmen. Semakin tinggi konsentrasi binder, semakin baik ketahanan luntur warna kain terhadap gosokan kering, gosokan basah, dan pencucian. Namun, semakin tinggi konsentrasi binder juga akan membuat handfeel kain semakin kaku. Berdasarkan hasil pengujian, konsentrasi binder 7% pada proses pencapan kain polyester dengan zat warna pigmen menghasilkan ketahanan luntur warna yang  kurang baik dilihat dari nilai gray staining-nya pada angka 3,walaupun daya handfeel-nya lembut. Sedangkan binder dengan konsentrasi 20%, memiliki kelunturan warna yang sangat baik dilihat dari nilai staining gray scale-nya pada angka 4-5, namun daya handfeel kainnya begitu kaku. Binder dengan konsetrasi 10% memberikan hasil yang lebih seimbang, dengan memiliki nilai staining gray scale 3-4 dan daya handfeel kain yang masih cukup nyaman. sehingga dapat disimpulkan bahwa konsentrasi binder 10% memberikan hasil yang optimal baik dari segi kelunturan warnanya dan sifat handfeel-nya.

Abstract

Penyempurnaan tekstil menggunakan senyawa resin merupakan salah satu usaha untuk memperbaiki sifat serat yang kurang dikehendaki. Penyempurnaan resin ini termasuk penyempurnaan kain secara kimiawi karena menggunakan zat kimia seperti resin sintetik. Bahan ini dapat digunakan secara eksternal dan internal, pada penggunaan eksternal senyawa resin hanya menempel atau terserap pada permukaan bahan saja. Hasil dan pembahasan pengamatan ini terdiri dari dua jenis variabel: variabel dependen dan independen. Dalam pengamatan ini, variabel dependen adalah mesin finishing stenter, sedangkan variabel independen adalah variasi resin terhadap kain polyester. Pada tulisan ini, disajikan data pengamatan yang diperoleh dari hasil variasi resin 60 gram/liter, 80 gram/liter dan 100 gram/liter. Analisis yang akan dilakukan adalah untuk memberikan gambaran seberapa jauh pengamatan mengenai pengaruh konsentrasi variasi resin pada proses finishing dengan mesin stenter terhadap hasil gramasi kain, hasil pengujian ketebalan kain dan efek handfeel yang ditimbulkan.
