Abstract

Pollution is one of the environmental problems in developing countries. Sources of pollution can be caused by nature and due to human actions. One of the air pollution sources is heavy metal content of Pb which is not easily decomposed in nature so that it can contaminate the environment. In Puring plants, especially the leaves have cellulose acetate which can filter heavy metals. The purpose of this study was the manufacturing of cellulose acetate from the leaves of the Puring plant. The cellulose obtained from the simplicia of leaves of the Puring plant will then be reacted into cellulose acetate through the acetylation reaction process using acetic anhydride with variations in temperature and reaction time taken, namely 40, 50, 60° C and as long as 50, 55, and 60 minutes. The levels of cellulose acetate were obtained through the cellulose extraction process, the synthesis of cellulose acetate and the final stage of making the membrane, from this process the optimum temperature and reaction time results were obtained in the second experiment with a temperature and reaction time of 50°C each and for 55 minutes without applying a catalyst 12.40%. In addition, the weight variation of raw material powder was taken, namely 20, 40, 60, 80, and 120 mg using a certain concentration of Pb (II) solution to determine the adsorbent capacity. These results can be obtained from analysis using Fourier Transform Infrared (FTIR).

Abstract

Biogas is a gas fuel produced by anaerobic activity or fermentation of organic materials, including human and animal waste, domestic (household) waste, or anaerobic degradation of organic materials by anaerobic bacteria. In this study, biogas was used as fuel with the addition of NaOH variations to the modified gasoline generator set engine so that it could work to produce electricity. This experiment used variations of 2, 4, 6, 8, and 10% NaOH nutrition with variations in the electric load of 10, 15, 20, 25, 30, 35, 40, 45, and 50 watts. These purposed to determine the performance of electric power, torque, and system efficiency. From the test, it found that the greater load of the lamp, the smaller performance of the electric power produced. The results showed that the greatest electric power was the variation of 2% NaOH nutrition with a lamp load of 10 watts, namely 39.33 watts. In the efficiency testing, the greater electric load system resulted efficiency system tent to be stable. The best system efficiency with 2% NaOH nutrition was compared to other nutritional variations. In testing of torque, the greater electric load torque resulted also greater torque. The greatest torque with 2%, NaOH nutrition compared to other nutritional variations.

Abstract

Indonesia is a high tourism sector country which provides opportunities for tour and travel service business. Thereby increasing the growth rate of accidents by 3.3%, one of which was caused by buses. Hafizh 58 Jaya, a company in the field of tourism services, had many complaints against drivers about the problem of muscle disorders due to the lack of ergonomic position of the driver or the seat used which was not suitable with the user or not ergonomic. To analyse this problem, IDEAS framework was applied. This method could describe overall minibus driver movement and produce designs that were appropriate with the level of risk on small musculoskeletal disorders. By normal driving activity, the second driver had the largest PEI parameter index value, 2,186. It was categorized as medium to low-risk musculoskeletal disorders. This meant that the actual chair with normal driving activity was not optimal and not ergonomic. The final design of the redesign chair has given optimal and ergonomic results shown by highest PEI index parameter value of 1,336. This PEI index parameter was categorized at the low risk of musculoskeletal disorders.

Abstract

The service business in Indonesia is growing every year and competition is getting tougher. One of the service businesses that is always growing is motor vehicle repair service. So that the vehicle service company must make service improvements to be able to compete. For this reason, the company needs to know the service performance so that the company must know the advantages and disadvantages of the services provided to customers. The purpose of this study is to measure the performance of vehicle service quality and determine service improvement priorities in increasing customer satisfaction and loyalty. The method used in this research is service quality and Analytical Hierarchy Process (AHP). The results of the study were to obtain 21 service attributes obtained from interviews. Then from the results of processing with the service quality method, it turns out that there is a gap in service quality based on perceptions and expectations because it is negative. So all the existing service attributes need to be improved. Meanwhile, the results of determining priorities that need to be improved on the 21 service attributes using the AHP method show that the mechanical speed attribute in car service is the first priority because it has the largest weight, namely 0.107. Then the service attribute that gets the last priority to be repaired is the equipment and equipment attribute with the smallest weight of 0.02 because the current dealer already has a fairly complete vehicle service tool.

Abstract

The research wants to test and analyse using a quantitative approach whether the existence of human capital and structural capital has an influence on company performance as measured by Economic Value Added (EVA). The population of this study is the financial statements of pharmaceutical manufacturing companies listed on the Indonesia Stock Exchange (BEI) from 2013 to 2018, with a sample size of 6 companies, the number of observations was 36 samples. The results of this study indicate that the management of human capital and structural capital has a positive but insignificant effect on company performance as measured by Economic Value Added (EVA) assessments, so that theoretically it does not support Barney and Clark's Resource Based Theory (RBT) theory, because there are still components of human capital and structural capital which quantitatively have a positive but insignificant effect. RBT theory states that companies have three types of resources, namely human resources (HR), organizational/structural resources, and physical resources that contribute to obtaining profitability. The three types of resources are an integral part that cannot be separated because they influence one another.
