The paper describes a method of incorporating knowledge and data of the production process into a concept design model in a way which provides a flexible and powerful structural design tool. Interactive graphics is shown to be a useful design aid when defining geometry and scantlings particularly when combined with a database of information on standardization, build methods and production technology. An effective method of assessing work content is presented in which man-hours are assessed for each phase in the construction process, that is, preparation, fabrication and erection. The total build cost, including labor, material and overhead, is used as the criterion in a series of studies which demonstrate the application of the method to concept design and which show the sensitivity of total cost to changes in various parameters of design and production.

Gas Turbine Blades

A design tool has been developed to calculate the natural frequencies of shrouded or unshrouded gas turbine blades in seconds to allow designers to perform aeromechanical frequency avoidance checks in the early concept design phase. The tool derives its inputs from a pitch-line aerodynamic calculation and a 1D structural design tool and uses a NACA-based airfoil section generator to create the airfoil sections. It then generates a shell-element based finite element model for the blade and disk sector, performs a pre-stressed modal analysis, and ranks the blades according to their frequency margins with specified aerodynamic drivers. Validation studies comparing this simplified model to high-fidelity solid element FEA models show the frequency error to be below 5% for most cases. The speed of this tool allows for frequency assessment of thousands of designs in a few hours allowing the designer to perform large spacefilling DoEs and select a flow path which minimizes the chances of fundamental mode crossings in later design stages..

This research is intended to compare and demonstrate the difference between the cost and benefit of organic farming and chemistry. Compare differences in the quality of yields and minerals in the soil both before and after cultivation and modeling of agribusiness. Using Business Model Canvas for the decision of agricultural entrepreneurs who want to modify the farming process.The research found that in the experiment comparing between the costs of Organic farming and Chemical farming to produce three types of vegetables that are cucumber ,red oak salad and radish, with the total cost of growing vegetables in Organic farming, higher than the total cost of growing vegetables in Chemical farming. There is a greater frequency of fertilizing and injecting Organic matter than chemical farming. The net profit from the sale of vegetables in the Organic agricultural sector is higher than the net profit from the sale of vegetables in the Chemical agricultural sector, as the production price of Organic agricultural sector is higher than the production price of Chemical agricultural sector because the production process of organic farming has a higher production process and requires higher production attention to produce quality, and another factor is that Organic vegetables have a higher production cost than vegetables from chemical farming, resulting in less volume of organic production in the market than vegetables from Chemical agricultural sector. Consumers are demanding more healthy Organic vegetables. As a result, the price of vegetables that produced by Organic agricultural sector is higher than the price of vegetables that produced by Chemical agricultural sector, and the Return on Investment in Organic vegetables is higher than the vegetables that produced by Chemical agricultural .The Return on Investment in production of Organic farming is 61.48% and The Return on Investment in production of Chemical farming is 33.87%. It is therefore possible to conclude that growing vegetables in Organic way is safe for vegetable farmers who do not have to be exposed to any harmful Chemicals, as well as the resulting produce that is safe from residues, allowing consumers to be safe from toxin residues and receive good quality vegetables.

The Cost

Locally load-optimized fiber-based composites, the so-called tailored textiles (TT), offer the potential to reduce weight and cost compared to conventional fiber-reinforced plastics (FRP). However, the design of TT has a higher complexity compared to FRP. Current approaches, focusing on solving this complexity for multiple objectives (cost, weight, stiffness), require great effort and calculation time, which makes them unsuitable for serial applications. Therefore, in this paper, an approach for the efficient creation of simplified TT concept designs is presented. By combining simplified models for structural design and cost estimation, the most promising concepts, regarding the cost, weight, and stiffness of TT parts, can be identified. By performing a parameter study, the cost, weight, and stiffness optima of a sample part compared to a conventional FRP component can be determined. The cost and weight were reduced by 30% for the same stiffness. Applying this approach at an early stage of product development reduces the initial complexity of the subsequent detailed engineering design, e.g., by applying methods from the state of the art.

Important Objective

ABSTRAK Pada umumnya harga pokok produksi dalam akuntansi diartikan dengan jumlah biaya dari seluruh pemakaian yang telah dilakukan selama proses produksi atau kegiatan yang mana mengubah bahan baku menjadi produk jadi (produk siap pakai/siap saji). Tujuan penting dalam tugas ini yaitu memperhitungkan harga pokok produksi dari UD Mulya Jaya dengan menggunakan pendekatan variabel costing untuk mengetahui besarnya harga pokok pada setiap produk yang diproduksi. Pentingnya penentuan harga pokok produksi dapat dilakukan sebelum para usaha menentukan harga jual. Pendampingan ini bertujuan untuk membantu mencari dan menentukan harga pokok produksi yang dapat digunakan untuk menetapkan harga jual. Pendampingan ini dilakukan untuk membantu wirausaha dalam program kerja, yaitu bimbingan akuntansi dengan fokus perhitungan harga pokok produksi. Dalam menentukan harga pokok produksi pada UD Mulya Jaya dapat menggunakan pendekatan variable costing yang biasanya metode ini digunakan untuk semacam pengambilan keputusan dalam perusahaan. Melalui program pendampingan kewirausahaan didapatkan hasil perhitungan harga pokok produksi yang menggunakan pendekatan variabel costing. Hasil tersebut dapat menjadi suatu keputusan bagi UD Mulya Jaya untuk dapat menetapkan harga pokok produksi pada setiap produk telur asin. Kata Kunci : Kewirausahaan, HPP, Harga.   ABSTRACT In general, the cost of production in accounting is defined as the total cost of all uses that have been made during the production process or activities which convert raw materials into finished products (ready-to-use / ready-to-serve products). An important objective in this task is to calculate the cost of goods manufactured from UD Mulya Jaya by using a variable costing approach to find out the cost of goods on each product produced. The importance of determining the cost of production can be done before businesses determine the selling price. This assistance aims to help find and determine the cost of production that can be used to set the selling price. This assistance is carried out to help entrepreneurs in work programs, namely accounting guidance with a focus on calculating the cost of production. In determining the cost of production at UD Mulya Jaya, it can use the variable costing approach, which is usually used for a kind of decision making in a company. Through the entrepreneurship assistance program, the results of the calculation of the cost of production are obtained using the variable costing approach. These results can be a decision for UD Mulya Jaya to be able to set the cost of production for each salted egg product. Keywords: Entrepreneurship, COGS, Price
