This paper presents a new study on profit optimization of abrasive blasting systems. In the study, the effects of many parameters such as the air pressure, the initial nozzle diameter, the cost components and the nozzle wear on the profit rate were investigated. Based on the results of the optimization problem, regression models for determination of the optimal exchanged nozzle diameter in order to get the maximal profit rate were proposed. With “optimal diameter”, both the profit rate and the cleaning time can be reduced significantly.

<p>Price changes affect all aspects of agricultural activities, especially on agricultural development.To increase the production of strategic commodities such as rice, maize, and soybean, needs special attention to the impact of price changes closely related to that trading, so it is expected that the implications for farming income will be better and can make farmers more prosperous in the future. Often the fact, the growth in food demand is faster than the growth of its supply, causing changes in the price of staple foodstuffs, and ultimately impacting at the farmers income whose are uncertain. This paper aims to analyze the impact of changes in rice,maize and soybean prices on that trading, and its implications for farm income. The determination of the Reference Price of Purchase which only considers the cost of farming to produce rice, corn and soybean has not provided optimal support for efforts to increase the income of pajale farming. Therefore, it is necessary to consider all cost components, as well as government intervention in helping to strengthen the bargaining position of farmers in the trading system of these three commodities in Indonesia, so that the supply chain from farmers to the hands of end consumers can be cut, in order to provide direct implications for increased farm revenues.</p><p>Abstrak</p><p>Perubahan harga memengaruhi seluruh aspek kegiatan pertanian, khususnya terhadap pembangunan pertanian. Untuk meningkatkan produksi komoditas pangan utama, seperti padi, jagung, dan kedelai diperlukan perhatian khusus terhadap dampak perubahan harga yang berkaitan erat dengan perdagangannya sehingga diharapkan pendapatan usaha tani menjadi lebih baik dan petani makin sejahtera kedepannya. Seringkali faktanya bahwa pertumbuhan permintaan pangan lebih cepat dari pertumbuhan penyediaannya yang menyebabkan perubahan harga pangan pokok sering bergejolak dan akhirnya berdampak pada pendapatan petani yang tidak menentu. Tulisan ini bertujuan menganalisis dampak perubahan harga padi, jagung dan kedelai terhadap perdagangannya, serta implikasinya terhadap pendapatan usaha tani. Penetapan harga acuan pembelian (HAP) yang hanya mempertimbangkan biaya usaha tani untuk memproduksi padi, jagung dan kedelai belum memberikan dukungan yang optimal bagi upaya peningkatan pendapatan usaha tani pajale. Untuk itu, perlunya mempertimbangkan semua komponen biaya serta intervensi pemerintah dalam membantu memperkuat posisi tawar petani dalam sistem perdagangan ketiga komoditas tersebut di Indonesia sehingga rantai pasok dari petani ke tangan konsumen akhir dapat dipangkas dengan tujuan dapat memberikan implikasi secara langsung terhadap peningkatan pendapatan usaha tani.</p>

In the field of software engineering, optimal scheduling of software is a well-studied concept. However, attention to cost analysis in the field of multi-upgradation is still limited to certain well- known works. In the present work, a mathematical framework for multi-upgraded software under the concept of imperfect debugging has been analyzed. With due consideration of the fact that upgraded version might contain some newly generated bugs and few latent bugs of its preceding version, the cost components have been designed in accordance. The parameter estimates of multi-upgraded software under the influence of imperfect fault removal process are used for optimal determination of release time. For validation purpose, a numerical illustration has been carried out on three releases of software and the optimal release time is estimated accordingly.

The blasting technique has been broadly utilized to prepare new surfaces for painting, engraving, etc., in industry. In fact, the minimization of the cleaning cost system is essential. However, the knowledge of this technique in terms of optimization has been poor so far. The aim of this study is to find the optimum replaced boron carbide nozzle diameter for the abrasive blasting system. The basis of the study is to find the replaced nozzle diameter to minimize the cost of the blasting system. Seven main parameters are adopted for examining their influences on the response and the optimum replaced nozzle diameter. The design of experiment (DOE) technique is utilized by using Minitab@19. The results reveal that the initial nozzle diameter has the strongest impact on the optimum replaced nozzle diameter. Furthermore, the proposed regression model has been found to be entirely insistent to the experiments. The utilization of this model can provide an effective way to simplify the calculation of the optimum initial nozzle diameter for boron carbide.
