Abstract

Cloud Manufacturing is an advanced manufacturing model which provides services by utilizing a shared resource pool such as computers, servers, networking, Internet and application softwares. The term Cloud Manufacturing in the engineering literature is still fairly new. it comes from the term Cloud Computing which is earlier known as Internet services on demand. Here includes Software as a Service (SaaS) along with infrastructure, platform and other delieveries as a service. First introduced by F. Tao in 2011, Cloud Manufacturing combines the latest technologies such as cloud computing, internet of thing, manufacturing object virtualizations and service-oriented computing services. The advanced manufacturing service models related to this terminology will be described as literatur reviews in this paper. At the end of this paper was given a case study of the application of the Cloud Manufacturing for designing a web-based production facilities layout as a cloud software as a service for the users.

Abstract

Grate the coconut is one of kitchen activity which faces by housewife in daily life. A coconut grater product which is distibuted in market, one of them is manual crank system. Housewife complain that they feel painfull in their body, especially at hand. Waist and back after using available old tool. This research is purposed to improve the design of coconut grater with crank system by ergonomic function deployment (EFD) approach, also to known mosculuskletal reducing of housewife as user and show differention time of grater after redesign done. Research was conducted in RT. 001 RW.005 Tembilahan, Indragiri Hilir District. Research model used treatment by subject design with total sample is 12 housewife which is calculation by Colton Formula. Improvement new coconut grater design with crank system which EFD got by creat the matrix house of ergonomic (HOE) and determination of anthropometry data. Mosculuskletal complain on housewife is measured by making the Nordic Body Map (NBM) Questionnaire work sheet. Time of grated the coconut got by testing coconut grater by crank system on before and after using. Research finding after redesign of coconut grater of crank system shown that design of coconut grater of crank system with EFD and base on ergonomic acpects (effective, confort, savety, healthy and efficient. Mosculuskletal complaint that happend on housewife decrease about 0,285 or 17,39%. Time of grate is also faster around 5 minutes or has imporove 30,1%.

Abstract

PT Semen Padang is a company that produces cement and it can not be separated from issues related to the effectiveness of the machinery/ equipment caused by factors such as six big losses. It can be indicated from the frequency of damage caused to machinery/ equipment because of the damage so that production targets are not achieved. Another result of damage caused by machinery/ equipment is the quality of products where the products are not meet the quality standards. Therefore, it is necessary to measure effective and efficient in the maintenance of machinery/equipment int term of solving such problems. TPM is a method which developed in Japan that can be applied to improve the productivity and efficiency of production. The applied method is one of useful methods to mantain machinery/equipment utilization including, losses that called by the six big losses. One goal of TPM is to increase the effectiveness to improve function and performance of machinery/ equipment used and reduce the six big losses contained in the machine/ equipment. Study has been conductedin W1 and W2 Kiln engine on Indarung Factory II / III PT Semen Padang. The first stage is measuring the effectiveness of W1 and W2 Kiln machine using OEE method. Furthermore, we are y measure OEE Six Big Losses and another losses that lead to the low efficiency of the Kiln machine. The data has been collected based on year 2013. Result showed that the value of OEE in W1 kiln ranged from 49% to 96%. While the value of OEE in W2 kiln ranged from 60% to 98% . It is related to the level of availability W1 kiln (average 92%) were also quite low when it is compared to the level of availability W2 kiln (average 94%) due to the length of time the kiln W1 engine damage. Refer to the value of the performance rate W1 and W2 kiln, it can be concluded that the average value of both engine performance rate is almost the same, ranging between 91% and 92%. Analysis of OEE Six Big Lossesshowed that cause of low OEE on kiln machine is breakdown loss. It also affected the reduced speed loss.

Abstract

PT Incasi Raya is one of the major companies in Indonesia which produce edible oils. One of the stages in the production activities are packaging products. Used packaging made of plastic material, with the capacity and different type. Plastic pouch is one of the few types of packaging used in the packaging of edible oils. Quality packaging affects the distribution of production to the consumer. If the packaging is damaged, then the product can not be distributed to consumers. Therefore, the quality of the packaging must be kept for the successful marketing of the product. One way to implement a quality control methods Statistical Processing Control (SPC). The data used in this study is a secondary data provided by the company. Data collected is the number of production reject every month in packaging activities. The data processing of the data collection that is making control map p. The results of data processing show that many reject the production of packaging that are outside the control limits. Data that are outside the control limits indicates there is a problem in the quality control of the company. Of all types of packaging, only one or two months of production reject packs that are in the control limits. This suggests that the dominant packaging reject each month of production is outside the control limits. Reject the production was analyzed using a causal diagram. Factors influencing the presence reject packaging production is based on the analysis of human, machine, environment, materials, and methods within the company. After analyzing of the causal diagram, the data is revision. Making a map of the proposed p controls the data that has been revised is the end result of the data processing is done. Quality control companies are advised to be on the boundary control such as control map p recommended.
