This study investigates the impact that marketing via social media has on the value of a brand. Building on the theory of uses and gratifications as well as the concept of brand experiences, our hypothesis was that the relationship between social media marketing activities and consumer benefits, such as brand awareness and value consciousness, is mediated by consumer experiences with brands, brand experiences, and participation in online communities. A survey with a total of 350 consumers who use social media and are actively engaged in branding was carried out, and the data collected from the survey were analyzed using a variety of statistical tools. The findings indicate that social media marketing had a significant impact on all aspects of the brand experience, including value consciousness, brand awareness, and brand experience.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88895186","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}

Mulieng Iceberg merupakan badan usaha yang bergerak dibidang industri yang memproduksi Es Balok. Pada proses pengangkutan es balok kedalam truk masih menggunakan sistem kerja yang manual dengan postur yang tidak sesuai dengan prinsip ergonomic sehingga menimbulkan keluhan musculoskeletal pada pekerja. Tujuan dari penelitian ini adalah untuk melihat hasil penilaian postur kerja terhadap pekerja dalam proses pengangkutan es balok kedalam truk dan juga usulan penambahan fasilitas kerja.

Dari hasil perhitungan QEC diperoleh pekerja 1 memperoleh nilai exposure level sebesar 81,82% dan pekerja 2 sebesar 82,39% dengan kategori perlu adanya tindakan perubahan secepatnya. Berdasarkan hasil perhitungan RULA pekerja 1 dan 2 memiliki kategori tindakan yang sama yaitu 7 dan tergolong dalam level risiko tinggi. Berdasarkan hasil perhitungan REBA  pekerja 1 mendapatkan skor akhir 8 sedangkan pekerja 2 memperoleh skor akhir 10 dimana pada tingkatan ini termasuk dalam tingkat risiko tinggi dengan action level kategori 3.

UD. Umega Hj. Eliya Lubis saat ini belum menerapkan perencanaan produksi yang baik untuk pelaksanaan produksi, pengusaha roti kacang melakukan perencanaan produksi hanya berdasarkan jumlah permintaan sebelumnya. Usaha ini sering dihadapkan suatu keadaan dimana adanya suatu ketidak pastian produk dengan banyaknya permintaan, karena banyaknya permintaan bersifat fluktuasi maka pengusaha roti kacang perlu memperhatikan kesesuaian banyak produk dengan permintaan konsumen agar tidak terjadi kerugian akibat produk yang berlebih dan terlalu sedikit. Berdasarkan permasalahan yang ada, diperlukan suatu perencanaan produksi menggunakan metode Goal Programming untuk pengoptimalan produksi roti kacang dengan bantuan software LINDO 1.6, metodeGoal Programming ditujukan untuk mengatasi masalah dengan lebih dari satu tujuan. Tujuan yang ingin dicapai perusahaana dalah memenuhi permintaan pasar, memaksimalkan keuntungan dan meminimalkan biaya produksi.
