Abstract

Bule-bule Garmen adalah salah satu industri garmen yang memproduksi berbagai macam variasi dari kain batik seperti kemeja, dress, tas, dompet, dan lain sebagainya. Berdasarkan hasil observasi awal, diperoleh dugaan sementara bahwa terdapat masalah postur kerja yang tidak ergonomis sehingga dapat menimbulkan gangguan musculoskeletal. Tujuan dari penelitian ini adalah merancang alat bantu untuk mengurangi risiko postur kerja operator. Proses analisis risiko postur kerja menggunakan metode Rapid Entire Body Assessment (REBA), sehingga diperoleh nilai postur kerja yang paling tinggi yaitu pada aktivitas penjahitan dan menginspeksi produk. Pada penelitian ini berfokus pada aktivitas mengispeksi produk. Tahapan selanjutnya yaitu perancangan alat bantu menggunakan proses pengembangan produk Ulrich dan Eppinger. Pada tahap ini diperoleh tiga alternatif konsep desain yang selanjutnya akan dipilih satu konsep desain yang paling baik. Konsep desain yang dipilih yaitu konsep desain dua. Konsep desain dua yaitu bak dengan sistem penggerak semi otomatis, mekanisme berupa automation use induction motor yang dioperasikan dengan menggunakan push button. Material rangka yang digunakan yaitu aluminium profil. Bentuk wadah yaitu bak, dengan material kayu. Simulasi dilakukan menggunakan software Jack dan diperoleh skor postur kerja yaitu 5 (sedang), dimana sebelum dilakukan perbaikian skor postur kerja yaitu 10 (tinggi).

Abstract

Development of prosthetic hands continues to be made to get prosthetic which has special characteristics, namely anthropomorphism. The anthropomorphic prosthetic design refers to the improvement and development of the design to the stage of the similarity of the prosthetic movement to human hand movements. This study carries the design of the anthropomorphic 1-DOF prosthetic finger mechanism to get prosthetic at an affordable price. The optimization criteria for the similarity of movement with the human hand are formulated with two objective functions, namely the similarity of the range of motion and the total length of the finger that is completed simultaneously. The human hand movement that is a reference is the movement of conical object grasping on a standard size conical according to the maximum hand-held diameter anthropometry of an Indonesian people.

Abstract

Cerebral palsy (CP) children are part of the neuro disability spectrum in impaired brain function. The etiological understanding of CP children for primary prevention and early treatment can reduce the effects of damage to brain function. CP children with cerebral diplegia are motor developmental disorders caused by damage to the brain characterized by weakness in the lower limbs heavier than the upper limbs. The walker product is designed through a universal design approach to provide as much as possible mobility to CP children in general. A universal design approach to the walker products through the triple helix collaboration included academic, medical devices industry and user institutions. Three subjects with spastic CP cerebral diplegia children underwent gait training using a walker. Gait performance (continuous walking distance, and maximum and comfortable walking speed) and energy expenditure are measured at the end of the 1-week training session. The purpose of the pediatric walker redesign is to facilitate mobilization of the position of the child's body CP in the anterior and posterior positions. The walker design can be removed from the raft back and forth from both sides at the front. At a certain time, the walker can be positioned behind the user according to the recommendations of some physiotherapy practitioners. This design also facilitates the position of CP children in order to be more precise, reducing double support during ambulation and increasing walking speed. The anterior-posterior walker as an ADVANCED walker for CP children provides the most appropriate position because it provides the best gait pattern and consumes less energy.

Abstract

Abstract.  Honey is a natural food product from a sweet viscous substance formed from flower nectar by honey bees. Honey processing using the pasteurization method has limitations, one of which is temperature. As a result, fungi and spores present in honey have not been eliminated. Non-thermal technology (NTT) is a solution to this limitation, because NTT is a process that applies little or no heat, with the aim of food receiving microbial inactivation, and can extend life, maintain physical quality, nutrition, and sensory freshness. NTT is commonly used in industry, namely in High-Pressure Processing (HPP), Pulsed Electric Field (PEF), Pulsed Light, Cold Plasma (CL), and Ultra Sound (US). Adjustment to the characteristics of honey is the reason for choosing non-thermal technology. The selection was carried out using the MCDM method, which integrates AHP-TOPSIS. The result is PEF being the selected NTT with a relative closeness of 0.773.
