This paper presents an example of how expert systems can be developed and used for planning structural piece-part production. First, expert systems are briefly and generically described. Then the production processes within a shipyard-like structural piece-part production facility are defined within an expert system "shell"; that is, the "objects," "attributes," and "rules" describing the production process are established and explained. Then various structural piece-parts are described to the system and the system identifies the required production processes for each described part. The inference process underlying the identification of these processes is described for each of these parts. Finally, potential applications of expert systems to other areas of shipbuilding operations are discussed.

Sulam bayangan merupakan produk sektor kreatif yang berkontribusi bagi produk domestik bruto namun menuntut efisiensi dan efektivitas untuk memenangkan persaingan antar pelaku usaha. Efisiensi akan mengurangi waste aktivitas produksi dan mengurangi biaya produksi yang dibutuhkan. Pada proses produksi kerajinan sulam bayangan masih terdapat waste berupa aktivitas yang tidak bernilai tambah yang berpengaruh terhadap output produksi. Permasalahan tersebut dapat diselesaikan dengan pendekatan lean manufacturing untuk menciptakan continuous improvement pada proses produksi dengan metode Activity Based Management (ABM). Penerapan ABM menciptakan efisiensi biaya yang menekankan pengelolaan bisnis berdasarkan aktivitas. Perbaikan yang dilakukan yaitu eliminasi dan penggabungan elemen kerja pemeriksaan motif dan sulaman. Hasilnya adalah efisiensi biaya produksi sebesar 4,89% dan waktu produksi sebesar 6,07%.   Shadow embroidery is a creative sector product that contributes to gross domestic products but requires funds and assistance to win competition among companies. Efficiency will reduce production waste and reduce the required production costs. In the process of producing shadow embroidery craft it is still a waste containing activities that are not added added to the production output. These problems can be discussed with lean manufacturing to create continuous improvement in the production process with the Activity Based Management (ABM) method. Implementation of AB Creating cost efficiency that governs business management based on activity. The improvements made are elimination and incorporation of work elements to examine motifs and embroidery. Total production costs amounted to 4.89% and production costs amounted to 6.07%.

This study aims to reduce the waste that occurs on each workstation and has an impact on increasing productivity and reducing production costs caused by waste that occurs during production. The data used for this study is quantitative data obtained by direct observation to the relevant departments regarding the problem of identifying waste that occurs — data taken from observations as much as 30 times the collection of data and historical data used from January 2016 to June 2017. By using the value stream mapping method on lean manufacturing, it can be seen that there are five types of waste from the existing seven waste. The five wastes are unnecessary motion, waiting, reject, transportation and in-process processes. From the results of the value stream mapping carried out a reduction in waste on each workstation with a total reduction of waste that occurs at 66.97 tons / year or 18.6% on waste gel and 88.8 tons / year or 19.3% at waste powder and there was a reduction in the changeover process for 45 minutes or 12.16% of the total changeover time before the improvement. Also, there was also an increase in the production process speed of 2 minutes 47 seconds or 4.52% from the lead time of the previous production process, 61 minutes 34 seconds to 58 minutes 47 seconds.

PT. Trijaya Teknik Karawang is a manufacturing company that produces spare parts, namely the piece pivot. The increased demand make the company parties need to analyze the ability to do the production to make it more effective and efficient in order to win the competition. Preliminary observations on the production floor they still present problems that are categorized as waste. Based on it, lean manufacturing Approach used to solve these problems. First of all the waste identified by mapping the flow of production using Value Stream Mapping (VSM). Then determined the dominant waste going through weighting waste using Waste Assesment Model (WAM) with the result that the inventory is the dominant waste. Next choose a detail mapping tools with Value Stream Analyze Tools (VALSAT) and determine the cause of waste inventory with fishbone diagrams that result, the causes of waste inventory is the breakdown of the machine, the operator of conduct material handling and less nimble, the distance between the machine and the system far, the production batch manufacture. Recommendations for improvements are the application of the system production of one-piece flow with investing buying transfer dies and adds to the human resources division maintenance. The identification of the problem causing factors of the dominant waste activity, namely waste inventory using Fishbone diagrams is lack of engine maintenance because it does not have a maintenance division and the production system used is batch manufacture that produces goods in lot size so that there are WIP parts in each production process.
