Matching Bobot Maksimum Masalah Penugasan Dalam Graf Bipartit

Suatu matching dalam graf G adalah subgraf 1-reguler pada G yang disebabkan oleh kumpulan dari pasangan garis yang tidak adjacent. Suatu matching merupakan matching maksimum bila matching tersebut mempunyai harga pokok maksimum. Matching dalam graf bipartit merupakan matching makshnum apabila tidak adanya path perluasan yang berkenaan dengan matching tersebut. Matching yang mempunyai jumlah bobot garis maksimum disebut matching bobot maksimum. Untuk menyelesaikan matching bobot maksimum masalah penugasan dalam graf bipartit kita dapat menggunakan Algoritma Hungarian Jonker-Volgenant. Algoritma ini mencari path perluasan dan matching baru serta mencari subgraf tambahan dari himpunan dual yang mempunyai variabel-variabel u; dengan vertex-vertex icS dan vi dengan vertex-vertex j e T . A matching in a graf G is a 1-regular subgraph of G, that is, a subgraph induced by collection of pairwise nonadjacent edges. A matching is called maximum matching if the matching has maximum cardinality A matching in bipartite graphs is maximum matching if there exist no augmenting path. A matching in where the sum of the weight of its edges is maximum is called maximum weight matching. To solve maximum weight matching of assignment problem on a bipartite graphs we can use Jonker-Volgenant Hungarian Algorithm. The Algorithm is to find augmenting path and the new matching, and to fmd additional subgraphs from the set of dual which have variables zit with vertices i e S and I); with vertices j e T

Synthesis and development of specialty chemical processes

The chemical processing industries (CPI) in the developed countries have shifted away from commodity chemicals towards the high-value-added specialty chemicals, which are the major ingredients in consumer products such as cosmetics, pharmaceuticals, and personal care products. The quality of these products depends not only on purity, but also on structural attributes such as droplet size, particle size, shape, and morphology. For this reason, the product requirements for specialty chemicals are much more complex than that for commodity chemicals. The widening product requirements lead to increasing process complexity, as indicated by three characteristic features. First, the product is normally a solid, and crystallization is commonly used in its recovery and purification. Second, handling of solids is required in most parts of the manufacturing process. Third, various ingredients with potentially very different forms and properties need to be combined to form the final, structured product. Besides the increasing product and process complexity, there is an intensifying pressure to shorten time-to-market. Therefore, it is very important that process synthesis and development of specialty chemicals is done quickly and effectively. In response to these challenges, a framework for systematic development of specialty chemical processes is presented. Systematic procedures are developed for selected key issues centered on three main themes: crystallization, solids processing, and consumer product manufacturing. These include the design and synthesis of crystallization-based separation processes, integrated crystallization-downstream processing systems, bulk solids processing systems, and dispersed systems. A general framework for product-oriented process synthesis and development is also presented. The procedures are presented in a step-by-step manner, guiding the user to first focus on the general problem, then progressively refine their thinking to address more detailed issues. There are three important components to each procedure. First, the engineering science principles behind the problem serve as the basis for the procedure. Second, related knowledge is systematized and summarized in the form of look-up tables, diagrams, and heuristics. Third, for quantitative comparison between process alternatives, shortcut models are used to obtain quick but reasonable estimates. Together, these components form a coherent framework for systematically solving the problem at hand

Pozzolanic Activity Assessment of LUSI (LUmpur SIdoarjo) Mud in Semi High Volume Pozzolanic Mortar

LUSI mud obtained from the mud volcano in Sidoarjo, Indonesia, is a viable aluminosilicate material to be utilized as pozzolanic material. LUSI is an abbreviation of the local name of the mud, i.e., Lumpur Sidoarjo, meaning Sidoarjo mud. This paper reports the results of an investigation to assess the pozzolanic activity of LUSI mud, especially in semi high volume pozzolanic mortar. In this case, the amount of mud incorporated is between 30 to 40 of total cementitious material, by mass. The content of SiO2 in the mud is about 30, whilst the total content of SiO2, Fe2O3 and Al2O3 is more than 70. Particle size and degree of partial cement replacement by treated LUSI mud affect the compressive strength, the strength activity index (SAI), the rate of pozzolanic activity development, and the workability of mortar incorporating LUSI mud. Manufacturing semi high volume LUSI mud mortar, up to at least 40 cement replacement, is a possibility, especially with a smaller particle size of LUSI mud, less than 63 μm. The use of a larger percentage of cement replacement by LUSI mud does not show any adverse effect on the water demand, as the flow of the fresh mortar increased with the increase of percentage of LUSI mud usage

Design of industrial wastewater treatment plants: a multi-faceted problem

Process synthesis, modeling, and experiments are the major components in designing industrial wastewater treatment plants. As industrial wastewater contains process-specific pollutants and is highly varied in nature, limited information is available in selecting the best treatment unit for a given industrial wastewater by heuristics. Experiments can complement the heuristics-based flowsheet development by determining the best treatment unit for the industrial wastewater and obtaining model parameters for a more reliable process simulation. This finally leads to a high performance and cost effective industrial wastewater treatment plant

Choosing Bio Ethanol Fermentation Process Combination with Two Levels Full Factorial Design Method

The reduction of oil energy reserve makes fuel increased in price. Therefore, alternative energy as a substitute to save fuel is needed. One of the alternative energy is bio fuel, and one of the bio fuel types is bio ethanol. The purpose of this research is to determine the best factors and level combination on bio ethanol fermentation process, in order to made bio ethanol with higher content. Cassava is used as the raw material of bio ethanol making process. This research was conducted using Two Levels Full Factorial Design method. Factors which are studied are the amount of urea fertilizer NPK (fertilizer) type, the amount of NPK, the amount of yeast, the amount of alpha amylase enzyme, and the amount of glucoamylase enzyme. Data was analyzed using ANOVA test, main effect plot, and interaction effect plot. As a result, type of NPK, amount of NPK, amount of alpha amylase enzyme, and amount of glucoamylase enzyme are factors that have a significant effect on the bio ethanol fermentation process. The best combination for this experiment is the amount of urea: 4.88 grams, type of NPK: 20/9/15, the amount of NPK: 1.4 gram, the amount of yeast 10 grams, the amount of alpha-amylase enzyme: 1.5 milliliter, and the amount of glucoamylase enzyme: 1.35 milliliter
