Different blanching treatments were applied to sliced broccoli stems prior to dehydration in order to improve product quality. The pretreatments used were a conventional blanching in water at 100°C, and a stepwise blanching using different temperatures for the first step (50, 55, 60, 65 and 70°C). Five rehydration temperatures were used (25, 40, 55, 65 and 80 °C). Rehydration rate, chlorophyll content and texture of the rehydrated product were evaluated. Rehydration was modeled based on Fick's diffusion equation. A good agreement between the model and the experimental data was obtained when D eff and W e values were identified for each temperature (average percent variation 99.3). Samples stepwise blanched at 60 °C showed, on average, the lowest We and Ea values. Stepwise blanching at 60 and 65 °C and rehydration at 25, 40 and 55 °C were the combinations that gave the firmest product. Stepwise blanching at 50 °C and rehydration between 25 and 65 °C was the combination that preserved the highest chlorophyll content. From these results, it seems difficult to obtain firm samples with high chlorophyll content without any chemical additive.

Case heater & case blower is one of component product used to make car air conditioner. The function of case heater & case blower is as a holder for various car A/C components. Case heater & case blower is produced with a mould with the support of plastic injection machine. The process is to inject the material melt into the mould. When the product comes out of the machine, it checks the product to remove the burr on the product. Burr is a minor type of defect in the product, meaning the product can still be said OK but an additional process should be done to clean the product. Additional process is called burritori, which is a process to clean burr by using cutter. Allowed burr standard of 0.1 ~ 0.3 mm, above it must be done burritori process. With the company's slogan of QUALITY FIRST, the quality of product is very important. Therefore the burritory process can not be eliminated. With the burritory process, so have additional man power to do that activity. Actually unneeded additional man power to do burritori process if product out of mould in good condition that there is no burr on product. This study aims to improve product quality by addressing the product burr problem after being out of mold. So with the increased product quality that is the absence of burr, then the burritory process previously done no longer need to be done because the product comes out of the mold already good quality (no burr). In this research using PDCA method in solving existing problems.

This study aims to determine whether Product Quality has an effect on Consumer Buying Interest. Speaking with quality and buying interest is certainly very tied to marketing. The essence of marketing according to Daryanto (2011) "marketing is a social and managerial process where individuals and groups get their needs and desires by creating, offering, and exchanging something of value with each other". This type of research is quantitative research with data analysis techniques using a skla likert research instrument, test validity, reliability, simple linear regression analysis and hypothesis testing. Based on the results of the study the influence of product quality is a variable that does not affect consumer buying interest. Then it can be concluded that product quality does not significantly influence consumer buying interest. If the quality of the product is good, there will be buying interest and consumers will feel satisfied. In this case, Pia Deisy's business must further improve product quality so that it will be more attractive and will have a good impact on Pia Deisy's home business.

An experimental and modeling approach was developed in this research to investigate the effects of CO2, new synthesized CaO and commercial SiO2 nanoparticle concentrations on the Asphaltene Precipitation Envelope (APE). First, the effects of different temperatures and CO2 concentrations on asphaltene precipitation trends were observed. Second, the impact of CaO and SiO2 nanoparticle concentrations on asphaltene precipitation were observed in the presence of CO2 at different temperatures. Third, Advanced Redlich-Kwong-Soave (RKSA) equation of state (EOS) was considered to modify Multiflash (Infochem Co.) software from the aspect of entering physical characteristics of CaO and SiO2 nanoparticles as pseudo components. Fourth, the developed model was used for predicting the effects of CO2, CaO and SiO2 concentrations on APE in ranges that no experimental data existed. At constant CO2 concentration and temperature during natural depletion, asphaltene precipitation increased above saturation pressure, while below saturation pressure, asphaltene precipitation decreased (solution gas evolved from crude oil and made it richer). As temperature increased at constant CO2 concentration, asphaltene precipitation decreased, while it was observed that the saturation pressures increased. Although two different trends were observed in upper asphaltene onsets at different temperatures and CO2 concentrations, in wide ranges of data, as temperature increased, asphaltene upper onset pressure increased. CaO and SiO2 nanoparticles decreased asphaltene precipitations in the presence of CO2, but CaO had better applications for reducing asphaltene precipitation. The proposed Software/RKSA EOS model was in good agreement with the obtained experimental data, and it was applicable for predicting the effects of CO2, CaO and SiO2 nanoparticles concentration on APE.

Break time results carried out for 60Ibs/Mgal linear gel at different breaker and activator concentrations with temperatures for gravel pack jobs done in the past was used in this study. Temperature range investigated was from 180oF to 215oF. A mathematical model was developed for break time prediction as a function of temperature and breaker/activator concentrations. The model was regressed with experimental data using the regression tool in Microsoft Excel. Results of the model prediction were validated with experimental data. The model break time predicted showed good agreement with experimental values with less than 2% deviation. The model equation developed will help predict the break time at the various breaker and activator concentrations at different temperatures. This will help in saving time associated with the rigour in actual laboratory experimental design and testing. This will no doubt improve operational efficiency and service quality delivery.

The tight competition in the business world requires every business actor to develop business with various kinds of competition in all fields, one of which is by processing human resources, because the quality of human resources greatly affects the quality of production. The production process is usually associated with productivity, if productivity increases it will also be followed by an increase in the performance of the company. Human Resources is one of the keys to the success of the company in order to increase competition and improve product quality. The method used in this study is a descriptive type of qualitative approach. The data collection technique was through observation, interviews and documentation, the data source being from UD Slamet Situbondo. The purpose of the study was to determine the effect of human resources on improving product quality. The results of the study indicate that the existence of quality possessed by human resources is very decisive for improving product quality in the future. For measuring product quality, it can be known through customer satisfaction, free from damage, the size of the durability of the product, product accuracy, and easy to operate and maintain. Meanwhile, from a marketing point of view, product quality is measured in terms of the buyer's perception of the quality of the product

The measurements of the zeta potential of five consolidated samples including natural and artificial ceramic rocks saturated with 5.0×10-3 M NaCl electrolyte at different temperatures have been reported. The zeta potential obtained in this work is always negative and increases in magnitude with increasing temperature for all samples (an average increase of the zeta potential of 0.4 mV/ oC in magnitude). The experimental results are in good agreement with previously published data. The experimental data is then explained by a theoretical model. It is shown that the model is able to reproduce the main trend of the experimental data from our work and from published articles.
