Abstract

Energy is one of the main needs in the current era. According to the law of conservation of energy, that energy can neither be created nor destroy, but energy can be change from one form to another. Energy can classify into two forms: the silent energy called the potential energy, and the moving energy called kinetic energy. The potential energy usually stored in raw energy sources are petroleum, coal, or still air. Kinetic energy usually stored in a negative energy source is wind or running water. Electricity is one form of energy that is widely used for various purposes a day. A lot of energy that turns into a form of electrical energy, one of which is petroleum. To simulate electrical goods by using electric energy more effectively. This paper a series of Double Brushless Direct Current Motor (BLDC) was create, to produce more effective motion energy in the utilization of electrical source. The prototype of this paper uses two equal BLDCs motor, one motor used as an AC generator to provide feedback from the resulting results. It expected that this prototype can be used as a tool of motion with effective electrical energy.

Abstract

Simulation of activity coefficients ternary systems using matlab programming language, which results in the appearance of the graph using a spreadsheet tool, less effective and efficient, so it is necessary for the visualization of object-oriented programming language, in addition to easy to be developed at a time when that will come, it has other benefits, in a device project software can use a variety of programming language that supports object-oriented programming, such as C#.Net and VB.Net. This research aims to display the batch distillation simulation of visual binary systems using object-oriented programming. Ethanol buthanol ethanol non azeotropic ternary system, simulation of activity coefficients with rigorous method using a model Differential-Algebraic-Equations (DAEs), where the completion of the model using the language C#.Net, the basic concepts of object-oriented programming consists of classes, objects, abstraction, encapsulation, polymorphism. Antoine parameter data and activity coefficients derived from experimental data. Dimension less time and pressure are set constant, while the variable composition liquida. Profile of liquida composition and vapor composition function dimensionless can be displayed directly from the desktop, to have the non azeotropic ternary system value profile activity coefficient is not equal to one, while the ternary system non azeotropic approaching one. Profile of liquida composition and vapor composition maximum from ternary system non azeotropic is 0.98, while for the ternary system non aeotropic approaching one. Economically using C#.Net language faster, time efficiency and better performance profile. Keywords: Activity coefficients, C#.Net, DAEs, rigorous method, ternary systems

Abstract

Every company needs to optimize and improve its performance. Performance improvement strategies cannot be well formulated if there has never been a performance measurement itself before. Determining the overall condition of the company can be done by assessing the performance of the entire lines of the supply chain. The SCOR model is considered appropriate for complex supply chain activities because it has a measurement process of plan, source, make, deliver, and return. The scale for each process in the supply chain is different, so the Snorm De Boer normalization technique is applied to equalize the assessment units for each criterion. Based on the performance indicator (PI) calculation, six PIs scores are below the average performance. Those six Pis are raw material planning, production planning, planning cycle time, yield, product defect from production, and the number of equipment maintenance. The six PIs are assessment indicators for the planning process and production process, so an improvement of the management system for both activities is essential to be carried out immediately to improve overall supply chain performance.

Abstract

Indonesia merupakan negara yang kaya akan sumber daya mineral berupa bijih nikel laterit. Bijih ini merupakan sumber utama logam nikel yang banyak dimanfaatkan dalam industri kimia salah satunya dalam pembuatan baja tahan karat. Salah satu cara pengolahan yang dapat dilakukan adalah proses ekstraksi padat-cair (leaching) pada kondisi atmosferis. Pada penelitian ini, dilakukan ekstraksi nikel dari bijih nikel laterit yang diperoleh dari Sorowako menggunakan pelarut asam nitrat yang bertujuan untuk mengetahui suhu dan konsentrasi asam nitrat optimum dalam proses ekstraksi. Penelitian ini dilakukan dengan memvariasikan suhu operasi sebesar 50℃, 60℃, 70℃, 80℃, 90℃ dan konsentrasi asam nitrat 3M, 4M, 5M, 6M, 7M. Analisis kandungan nikel hasil leaching dilakukan menggunakan Atomic Absorption Spectroscopy (AAS) yang kemudian dioptimasi dengan menggunakan metode Response Surface Methodology (RSM) menggunakan aplikasi Minitab 19. Hasil penelitian menunjukkan bahwa suhu dan konsentrasi asam nitrat berpengaruh terhadap perolehan nikel. Kenaikan suhu dan konsentrasi asam nitrat akan meningkatkan perolehan nikel. Hasil terbaik pada proses ekstraksi yaitu pada konsentrasi asam nitrat 7M dan suhu 90℃ dengan perolehan nikel sebesar 80,73%. Setelah dilakukan proses optimasi hasil dengan metode Response Surface Methodology (RSM) menggunakan aplikasi Minitab 19 didapatkan persentase nikel terekstrak optimum sebesar 80,8727% pada konsentrasi HNO3 8,2M dan suhu 98,5℃.

Abstract

Plastic food packaging has become a part of human daily life. The management of plastic waste is a matter of concern due to its potential which is difficult to decompose. This condition causes all producers to have a responsibility not only during the manufacturing process but until the end of the life of their products. This expanded responsibility is called EPR (Extended Producer Responsibility). Therefore the resulting packaging design becomes a breakthrough in this matter. This research attempts to apply the Kansei Engineering method to capture customers' emotional needs from consumers in compiling plastic packaging design parameters. The research method in this paper uses the Kansei Engineering method, namely by collecting Kansei words from respondents at random, then the Kansei words are reduced. The reduced Kansei word will be synthesized to produce quality attributes that are able to meet the customer's emotional needs. The Kansei words obtained from the survey results are 55 words. Packaging quality attributes that have met the customer's emotional needs include protection, refillable, recyclable, biodegradable, food safety, additional function, attractiveness, conformity, ergonomic, user friendly, and content declaration (on the packaging label).
