  • PENERAPAN TAGUCHI DALAM OPTIMASI PARAMETER UNTUK PERBAIKAN PRODUK FACIAL
           WASH

    • Authors: Faula Arina, Ahmad Bahauddin, Anggie Maurdi
      Pages: 1 - 10
      Abstract: PT X is a company engaged in the cosmetic sector. The product with the biggest defect is the green tea tree oil facial wash. This study aims to reduce the number of defects by determining the optimal level setting on the  product. The Taguchi method is one of the methods in the experimental design that can be used to control product quality from noise by minimizing variations. This research method uses Taguchi because this method combines experimental results through optimal factors and factor levels and at the same time reduces the number of experiments so as to save time and costs. The experimental factors are water, Nacl, cocamide DEA, citrid acid, mixing speed, mixing time and mixing temperature. The results of this study found that the dominant type of defect in the  green tea tree oil facial wash products was the product with low viscosity. In this case, we used a nominal-is-best quality characteristic with a target of 37500 cPs. We found that the optimal setting for green tea tree oil facial wash products were 64.3% of water, 2% of cocamide DEA, 0.3% citric acid and 60 minutes for the mixing period.

  • PEMETAAN KEMIRIPAN BERDASARKAN KUALITAS APLIKASI MARKETPLACE MENURUT
           PELANGGAN

    • Authors: Niko Dwi Haryanto, Anas Alrasyid Putrawidya Buana
      Pages: 11 - 19
      Abstract: This study aims to prove the superiority of Tokopedia, Shopee, Bukalapak, JD.ID, Lazada and Zalora based on the quality of applications made by users of these applications. The sample in this study amounted to 30 people using accidental sampling technique. Operationalization of variables in this study consists of performance, reliability, features, conformance, durability, serviceability. aesthetic and perceived quality. The data analysis technique in this study used multidimensional scaling analysis. This study maps 6 marketplaces into 4 different quadrants, quadrant 1 consists of Lazada, quadrant 2 consists of Shopee and JD.ID, quadrant 3 consists of Bukalapak and quadrant 4 consists of Tokopedia and Zalora. The conclusion of this study with overall view indicate that there are 3 marketplace groups that have similarities, group 1 consists of Bukalapak and Lazada, group 2 consists of Shopee and finally group 3 consists of Tokopedia, JD.ID and Zalora. Through the division of these groups, it is assessed that group 1 (Bukalapak and Lazada) has a poor application quality, while group 2 (Shopee) has a good application quality and finally group 3 (Tokopedia, JD.ID and Zalora) has a best application quality.

  • PENERAPAN METODE HUNGARIAN DAN APLIKASI QM UNTUK MEMINIMALISASI KOMPLAIN
           KEBERSIHAN DARI KLIEN

      Abstract: An outsourcing company with a work contract period can run well if the work agreement made by the client is carried out properly. One of the things that affect the contract period is client complaints. By minimizing client complaints, the sustainability of work contracts between outsourcing companies and client companies is getting higher. For this reason, outsourcing companies assign workers based on the abilities of each worker so that the work results are optimal. One of the methods in solving assignment problems is the Hungarian method and the QM application. The purpose of this research is to minimize the value of hygiene complaints from clients. The results showed a reduction in the value of 15 client complaints from 43 complaints to 28 complaints related to the completion of the assignment of employees of outsourcing company using the Hungarian method and the QM application.

  • ANALISIS KESESUAIAN LAHAN DAN PENERAPAN TEKNOLOGI BUDIDAYA TAMBAK
           BERWAWASAN LINGKUNGAN DI KABUPATEN BONE

    • Authors: Toto Hardianto, Agnes Puspitasari Sudarmo, Nurmala Pangaribuan
      Pages: 33 - 44
      Abstract: Adanya peningkatan jumlah penduduk maka jumlah pembudidaya tambak cenderung semakin bertambah sebagai alternatif mata pencaharian bagi masyarakat pesisir di Kabupaten Bone.  Hal inilah yang  dapat menyebabkan kerusakan lingkungan pesisir sehingga perlu adanya pemanfaatan wilayah pesisir secara berkelanjutan. Penelitian ini bertujuan untuk mengetahui kesesuian lahan,penerapan dan pengembangan teknologi budidaya tambak sehingga potensi sumberdaya yang tersedia dapat dimanfaatkan secara optimal dan lestari.  Metode penelitian yang digunakan adalah metode survei yaitu mengumpulkan data dari sampel yang diambil secara acak terdiri dari 59 rumah tangga perikanan dan kesesuaian lahan tambak menggunakan Sistem Informasi Geografis.Hasil Penelitian menunjukkan bahwa Kelurahan Waetuo dengan luasan tambak 343,288 ha memiliki luasan tertinggi dengan rincian S1 = 297,303 ha dan S2 = 45,985 ha.  Sementara itu, Kelurahan Bajoe memiliki luas tambak terendah yaitu 57,036 ha dengan rincian S1 = 35,958 ha dan S2 = 21,078 ha.  Jika ditinjau dari penerapan teknologi, pada umumnya pembudidaya tambak yang ada di lokasi penelitian menggunakan sistem teknologi tradisional yaitu secara polikultur sekitar 88 % sedangkan monokultur hanya 12 %.  Berdasarkan hasil penelitian disimpulkan bahwa lahan tambak di Kecamatan Tanete Riattang Timur sudah sangat sesuai dan pada umumnya menggunakan sistem teknologi tradisional secara polikultur.Penelitian ini bertujuan untuk mengetahui kesesuaian lahan, penerapan dan pengembangan teknologi budidaya tambak sehingga potensi sumber daya yang tersedia dapat dimanfaatkan secara optimal dan lestari.
