Abstract

Depo Interior merupakan perusahaan interior yang menghasilkan mebel. Perusahaan ini belum dilengkapi dengan fasilitas dan metode kerja yang baik, sehingga pekerja sering mengalami keluhan rasa sakit dan lelah pada bagian-bagian tubuh tertentu. Dalam bekerja postur tubuh yang tidak baik dan pengulangan pekerjaan yang tinggi beresiko besar terhadap penyebab penyakit tulang belakang. Penelitian bertujuan untuk mengidentifikasi dan mengevaluasi postur kerja yang tidak baik bagi pekerja bagian finishing. Postur kerja diamati dengan metode Rapid Upper Limb Assessment (RULA). Pengamatan dilakukan pada 2 elemen pekerjaan yaitu pengamplasan dan penyemprotan. Langkah berikutnya : (1) tubuh dibagi menjadi dua bagian, yaitu kelompok A dan B, (2) pengelompokan skor postur bagian tubuh, (3) pengembangan grand skor dan daftar tindakan.

Abstract

The aim of this study is to design a batik coloring machine using the Quality Function Deployment (QFD) method in order to increase the value of fading and stains on fabrics. It can be concluded that the results of the design of batik coloring machines according to the application of QFD have 3 rollers/cylinders and propulsion about 0.190 HP with the working concept of a sheet of cloth wrapped around the cylinder with rotation of 72.5 rpm. There are significant differences between variables in the design before and after the experiment on the batik value quality analysis of soap washing and desecration of unbleached plain cloth of Primisima type, Gamelan stamp. The average difference between before and after the experiment is 0.060 or increase to 6%, while for the analysis of batik quality test, the value of rubbing dry and wet cloth has a mean difference between before and after the experiment of 0.100 or an increase of 10%. Standard time generated from the measurement process using a machine dipping carried out by 20 batik makers has a value of 0.2701 hours/ unit with total output of 4 units/ hour, while standard time for coloring activities that uses a bucket dip is 0.5346 hours / unit with total output of 2 units/ hour.

Abstract

One aspect that needs to be assessed to make better product is usability.  Testing the level of usability on BIMO hand is performed using adapted Southampton Hand Assesment Procedure (SHAP) method. Users are given the task of using prosthetic hand to perform daily activities according to performance measurement rules. Based on the opinion of Jacob Nielsen, the theory used to measure usability are 5 main parameters, i.e: Learnability, Memorability, Efficiency, Satisfaction, and Errors. Testing is done by giving 15 task daily activity to the respondent. After testing, respondents were given USE questionnaires (Usefulness, Satisfaction and Ease of use) as a media for usability assessmentand received suggestions from respondents. Some suggestions were obtained from the respondents after the research was conducted, such as the size of the product, censoric product respond, the suitability shape and weight of product. Based on the percentage of USE questionnaire assessment known Usability Prosthetic hand level tested is in the status of GOOD, this indicates the respondents feel the product is good to use.

Abstract

Losses caused by unreliable machines in a production line will affect the total cost losses from a manufacturing company's production process. Based on historical data of damage that has been obtained from the maintenance department of XYZ companies, the MACH MWJ 9/10 Shot Blast Machine is the machine that has the highest-level frequency of damage. This machine is useful for cleaning sand or residual production dirt that sticks to workpieces that have been cast in the casting process, especially for E-Clips components. The research's purpose is to determine the value of cost losses due to machine unreliability using the Cost of Unreliability (COUR) method, with Business Consequence analysis (BC) analysis. The cost effects of these costs include Corrective COUR and Downtime COUR. The final calculation of COUR shows that the total cost of COUR Downtime caused by the unreliability of the machine is greater than the total Corrective COUR. After calculating the COUR, an analysis of the business consequences resulting from the machine's unreliability is carried out using a risk matrix. The analysis results show that the shot blast machine's critical components are in the red or high-risk category and have a very high Probability of Failure (PoF). The results of COUR analysis with business consequence analysis will be an input for the company to make a machine maintenance system policy, especially for the MACH MWJ 9/10 Shot Blast machine's critical components. In general, this research's novelty is to combine the application of the Cost of Unreliability method with an analysis of the effects of the Business Consequence caused by the machine's selected critical components.

Abstract

Banyak orang yang salah mengambil langkah dalam melakukan suatu investasi, mereka akan segera tergiur dengan suatu hal  baru yang menurutnya menguntungkan. Padahal masih ada hal lain yang jauh lebih menguntungkan namun minimnya pengetahuan membuat mereka hanya mengetahui luarnya saja. Maka dari itu dengan dilakukannya penelitian ini diharapkan para investor lebih teliti dalam melakukan investasi terutama dengan minimnya biaya. Dengan menggunakan ekonomi teknik dan forecasting terhadap nilai kurs tukar kita akan mengetahui investasi mana yang lebih menguntungkan dengan ketentuan biaya tertentu. Dalam penelitian ini dilakukan perbandingan investasi di bank dan emas dengan dana 15 juta Rupiah yang hasilnya adalah investasi emas akan lebih menguntungkan meski bunga bank yang ditawarkan cukup tinggi.

Abstract

CV Poetra Mandiri Karton is a company that has not been able to meet production target each day.  Based on preliminary analysis, production underproduction was due to workers’ fatigue caused by manual material handling activities in the entire production process.  To solve these problems, nordic body map (NBM) approach was applied.  Prior to work, workers experienced musculoskeletal fatigue at down waist, and they experienced musculoskeletal fatigue at up waist, left forearm, right forearm, left hand, right hand, left ankle, and right ankle after work. Based on questionnaire of National Aeronautics and Space Administration Task Load Index (NASA-TLX), average of mental workload from all three groups is quite heavy.  By using rapid entire body assessment (REBA), it is found that average value of the risk in group 1 and group 2 requires immediate action, whereas action is required by the third group.  This article also presents a trolley design that will be used in manual material handling activities.

Abstract

Dalam penelitian ini, untuk meningkatkan kinerja OHMS yang karakteristiknya lebih kompleks, digunakan soft systems methodology yang banyak membantu para manajer untuk menyelesaikan masalah yang bervariasi dan kompleks. Permasalahan tersebut sering menemui kegagalan dalam penyelesaiannya ketika pendekatan system engineering (SE) digunakan. Penelitian menunjukan gambaran aktivitas lebih jelas, dan penentuan indikator lebih terstruktur dengan mengkombinasikan IDEF0. Melalui soft systems methodology yang dikuantitatifkan pada langkah debating menunjukan aktivitas A4, yaitu membuat produk, paling penting dengan bobot 35,32%. Dari hasil dekomposisi aktivitas kritis meliputi A12: merencanakan program produksi dengan bobot 9,17%, A41: mengendalikan produksi dengan bobot 9,17%, A32: mendapatkan kapasitas produksi, dengan bobot 8,72% dan A45: mengetes rakitan akhir dengan bobot 8,72%. Selanjutnya kinerja yang perlu dicermati pada ICOM’s (Input, Control, Output, Mechanism), lebih banyak pada input aktivitas kritis.

Abstract

Work posture analysis plays an important role in providing safe and productive workplace, through minimizing musculoskeletal symptoms or disorders. The postural analysis can be conducted through observation, direct, and self-report method. Each has their advantages and disadvantages. Purpose of this study is to compare obervation and self-report analysis in the context of degre of agreenes. One rater observes and gives rating to the fifteeen work postures in an automotive service company using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA). In addition, six workers in the automotive service company also fill out the Nordic questionnaire as a self-report of musculoskeletal symptoms or disorders. Descriptive analysis is conducted to compare the musculoskeletal symptoms using both observer and self-report analysis. Results show that RULA is slighlty better than REBA in accordance to the Nordic questionnaire’ result. Implications of the result is discussed.
