{"title":"Master block pattern development for fit evaluation based on adult female anthropometric data and body shapes using Telestia-AB patternmaking system","authors":"N. Zakaria, R. Tajuddin","doi":"10.31580/ojst.v5i1.2604","DOIUrl":"https://doi.org/10.31580/ojst.v5i1.2604","url":null,"abstract":"Developing well-fit garments is relevant in the garment industry, especially to achieve the quality of corporate uniform wear. A garment that looks good must also fit the body. The first process for garment fitting is to develop the body pattern that acts as the form for body shape before translating it to the desired garment design. Thus, the focus of this study is to construct a good master block pattern that fit the body well. Size, shape, and proportions are considered factors that contribute to a well-fitted garment. This study involves anthropometric study, master block development, pattern assembly onto fabric, basic garment constructions, and fitting analytics. The fit analytics are a relevant part of a fit evaluation to model the best method to develop body patterns and wear analysis for each individual for better-fit garment consumption. The conclusion showed that using sophisticated Telestia-AB tools and Telestia body key dimensions expedites the process of body block pattern for fit evaluation. The wear trial process is to determine how the bodice block fits before transforming it into the design pattern for corporate wear. This research concludes that developing a proper body pattern based on the anthropometric data is crucial as the fit of the garment is achievable with the right pattern-making system and skillset.","PeriodicalId":19674,"journal":{"name":"Open Access Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90050436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tidak hanya mengikuti mekanisme yang tepat tetapi juga harus mengikuti aturan hukum yang berlaku. Namun ditemukan kejadian saat barang bukti yang dihadirkan dipersidangan ditolak pada perkara nomor: 85/PID.B/2012/PN.pwt, dikarenakan hasil rekaman CCTV tidak disertai alat bukti proses hashing yang dicetak dalam bentuk surat untuk melihat keaslian dari suatu file. Hal ini menunjukkan bahwa pihak pengadilan tidak bisa menerima begitu saja bukti yang diserahkan jika mereka tidak bisa memastikan bagaimana bukti tersebut ditangani. Oleh karena itu, dilakukan penelitian untuk menghasilkan framework penangan awal untuk forensik CCTV melalui identifikasi ketentuan dan proses penting dari standar yang berlaku. Pengamatan pada penelitian ini menggunakan kolaborasi dari dokumen SNI 27037:2014 dan SWGIT 1.0 2013.09.27, sehingga diperoleh tahapan kegiatan terhadap alat bukti digital dimulai dari perolehan hingga diputarkan di pengadilan, dan sesuai dengan prosedur ini maka alat bukti digital tersebut dinyatakan sah di persidangan.
