Abstract

UD. Dhika Putra is a tahu manufacturing company. Currently, the company is having some problems in production facility layout and physical environment. This study aimed to redesign the facility layout of tahu manufacturing company to minimize the path length of material handling and apply the 55 method to enhance work productivity. The approach used to redesign the plant facility layout is Systematic Layout Planning (SLP), which can be categorized in three stages, namely material flow analysis, research, and selection. While the 55 method consist of several steps to organize workplace condition that affect on the effectiveness, eficiency, productivity, and safety. This study concluded that the chosen layout for the final layout showed a significant decrease in path length of material handling, i.e 45 meters or about 19,2%. The decreasing of material handling path length on the choosen layout was also influenced by the arrangement of the work place by using 55 method.

Abstract

Intisari— Dunia industri di indonesia mengalami perkembangan yang pesat. Perkembangan industri ini tidak lepas dari sektor formal dan informal. Salah satu perkembangan industri informal yaitu bidang pengelasan. Pengelasan adalah teknik penyambungan antara dua buah logam atau lebih dengan memanfaatkan energi panas. Aktivitas para pekerja las tersebut dilakukan dengan posisi badan membungkuk dan jongkok selama ber jam-jam hingga proses pengerjaan suatu produk selesai. Hal ini dapat mengakibatkan pekerja mengalami keluahan otot dibeberapa bagian tubuhnya. Keluhan tersebut terjadi pada bagian leher, punggung, lutut, dan kaki. Salah satu dampak resiko pada kesehatan dan keselamatan kerja yang dihadapi oleh pekerja bengkel las adalah keluhan musculoskeletal disorders (MSDs). Penelitian bertujuan untuk Mengetahui tingkat resiko ergonomi berdasarkan metode loading on the Upper Body Assessment (LUBA) dan Merancang alat bantu cekam (Fixture) yang ergonomis. Metode LUBA (Loading on the Upper Limb Assesment) adalah metode pemberian kode postur tubuh duduk atau berdiri dengan memberikan bobot tambahan untuk postur yang sesuai dengan hasil percobaan dari kondisi ketidaknyamanan yang dirasakan oleh sendi dari individu, Loading on the Upper Limb Assesment merupakan suatu teknik untuk pembebanan postural pada penilaian atas tubuh. Abstract—The industrial world in Indonesia is experiencing rapid development. The development of this industry cannot be separated from the formal and informal sectors. One of the informal industry developments is the welding field. Welding is a technique of connecting two or more metals by utilizing heat energy. The activities of the welding workers are carried out with the position of the body bending and squatting for hours until the process of completing a product is completed. This can result in workers experiencing muscle exhaustion in some parts of their body. These complaints occur in the neck, back, knees and legs. One of the effects of risk on occupational health and safety faced by welding workshop workers is a complaint of musculoskeletal disorders (MSDs). The study aimed to determine the level of ergonomic risk based on the Loading on the Upper Body Assessment (LUBA) method and Designing an Ergonomic Fixture tool. The LUBA method (Loading on the Upper Limb Assessment) is a method of coding the posture of sitting or standing by giving additional weight to the posture that matches the experimental results of the conditions of discomfort felt by the joints of individuals, Loading on the Upper Limb Assessment is a technique for postural loading on the assessment of the body.

Abstract

Inovasi dalam pembuatan batu bata saat ini memiliki tantangan semakin berkurangnya ketersediaan bahan material dasar tanah lempung sebagai bahan utama pembuatan batubata merah sebagai material utama pembangunan perumahan. Untuk menyiasati hal ini, diperlukan suatu alternatif bahan material komposit untuk mengimbangi laju permintaan batu bata yang berakibat pada laju pemakaian bahan dasar tanah lempung dalam produksi batubata merah. Untuk itu penambahan limbah biomassa berupa serbuk gergaji kayu karet dianggap sebuah solusi untuk memproduksi komposit batubata merah berbasis biomassa. Dalam kajian ini, produk komposit serbuk kayukaret dengan tanah lempung menjadi batu bata merah diteliti nilai karakteristik mekaniknya.Proses pembuatan batu bata merah dengan tambahan limbah kayu karet dilakukan dengan metode desain ekperimen dengan beberapa pengujian seperti :(i) uji kuat tekanan dimana hasil terbaik sebesar 61,98% dan termasuk standar SNI mutu kualitas III dan (ii) uji serap air, diperoleh nilai daya serap air terendah sebesar 21,75% dengan tambahan 5% serbuk kayu karet. Untuk Harga pokok produksi batubata komposit ini diperoleh sebesar Rp. 232/unit lebih rendah dibandingkanharga bata konvensional yaitu sebesar Rp.250/unit. Break Even Point diperoleh sebesar 3981 unit selama 4 bulan dan sangat menguntungkan jika diproduksi. Kata kunci:  Batu Bata Merah, BEP, Desai Eksperimern, HPP.

Abstract

Lean construction (LC) presented innovative practices to maximize the production value and minimize the production waste during construction. The problem that frequently occurs in the project is delaying the schedule, leading to time and cost overrun. This research aims to eliminate waste that causes delay and inefficiency. Several LC techniques were carried out to improve the efficiency of this project, namely: Value Stream Mapping (VSM) to discover wastes and determine Process Efficiency Cycle (PCE); Waste Assessment Model (WAM) to identify the inter-relationship among wastes; Fishbone (Ishikawa) diagram analysis to get the root cause of the waste. Research results showed the three highest wastes: defect 14.06%, overproduction 21.44%, and the highest rank was unnecessary inventories 31.73%. After implementing LC techniques, the PCE increased from 72 % to 79%. The implication of this research is to provide recommendations to project stakeholders in running the building construction to avoid delay and inefficiency.
