Abstract

Simulation of batch distillation binary 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 Mat lab programming. Ethanol-water azeotropic binary system examples and Acetone-Butanol, Acetone-Ethanol, Butanol-Ethanol zeotropic binary system examples, simulation of batch distillation with rigorous method using a model Differential-Algebraic-Equations (DAEs), where liquid vapor equilibrium in batch distillation process from cellulose (Bamboo) with Antoine equation. Profile of liquida composition and vapor composition function dimensionless can be displayed directly from the desktop, to have the azeotropic binary system value profile activity coefficient is not equal to one, while the binary system zeotropic approaching one. Profile of liquida composition and vapor composition maximum from binary system azeotropic is 0.98, while for the binary system zeotropic approaching one. Economically using Mat lab language faster, time efficiency and better performance profile.

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

Shelf life is information that must be included in food product packaging. Estimated shelf life of food products can be done conventionally (Extended Storage Studies) and acceleration (Accelerate Shelflife Testing). Estimation of shelf life by ASLT can be done using the critical moisture content approach, especially for products easily damaged by water absorption. The purpose of this study was to determine the shelf life of Soneca biscuits packaged using three different packages, namely Polypropylene (pp) plastic packaging, Metalized Plastic, and Aluminum foil. The method of determining the shelf life used in this study uses the ASLT method with a critical moisture content approach. Based on the research, it is known that the critical moisture content of biscuits is obtained when the product moisture content reaches 0.0812 (g H2O/g). The isothermic sorption curve of the biscuits obtained can be appropriately expressed using the Hasley model equation. Estimation of shelf life was carried out under storage conditions at 30 oC and 75% RH. The study results show that the predicted shelf life of biscuits with metalized plastic VM-PET packaging is 17.76 months, with aluminum foil packaging is 19.85 months and using PP plastic packaging is 1.72 months. Therefore, it is known that the best shelf life is the use of aluminum foil packaging.

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

Selection of Saccharomyces Cereviceae (SC) wastewater as a component produced by PT. Enero comes from a fermentation process that uses SC yeast, it’s availability is great and it has not been used as a raw material for glucose, which until now has been industrial waste. Efforts have been made to convert SC waste water into liquid fertilizer and biodiesel feedstock. The recovery of glucose from SC waste water in the chemical hydrolysis process using the reaction surface method (RSM), the hydrolysis process was carried out with a digital stirrer at a rotation speed of 200 rpm and the addition of 5 ml of 10% NaOH. The variables used were 50–250 mL SC waste water and 10–30 mL HCl volume. The optimization results using RSM of the chemical hydrolysis process are shown in three-dimensional graphs, pH and SC waste water ratio and HCl volume, glucose content and SC waste water ratio and HCl volume. The best results with SC waste volume of 8.58 mL and HCl volume of 34.14 mL achieved a pH of 4.38. In order to achieve a pH of 4.5, a hydrolysis process is carried out because the pH of the SC waste water is very acidic, i.e. 3.5, and 10% NaOH is added to increase the pH. The result of glucose from the hydrolysis process is 17.96%, the required volume of waste water SC of 137.14 ml, the addition of 34.14 ml of HCl as a raw material for the fermentation process. Based on the optimization results using RSM and chemical hydrolysis method, the glucose content is 17.96% and the pH is 4.38 with the SC water waste volume of 137.14 mL and the HCl volume of 34.14 mL.
