Abstract

This study aims to analyze the the determinants of employee performance at the Regional General Hospital of Sumbawa Regency which consists of work quality (X1), work discipline (X2), and work ethic (X3). The type of this study was causal associative which aims to determine the influence or relationship between two or more variables. The data used in this study was quantitative data obtained directly from respondents using a questionnaire. The number of samples used as respondents in this study was 85 people who were selected using accidental sampling techniques. The data that has been collected was processed using the SPSS application to be studied using multiple linear regression analysis techniques, partial parameter hypothesis testing (t test), simultaneous parameter hypothesis testing (F test), and determinant coefficient test (R2). The results of this study showed that partially the work quality had a positive and significant effect on employee performance, meanwhile, work discipline and work ethic did not have effect on employee performance at the Regional General Hospital of Sumbawa Regency. Simultaneously, work quality, work discipline and work ethic had an effect on employee performance at the Regional General Hospital of Sumbawa Regency. Furthermore, the ability of work quality, work discipline and work ethic to influence changes in employee performance at the Regional General Hospital of Sumbawa Regency was very weak, namely 21.3%, so it is hoped that future research can use other variables not examined in this study, such as work competency, work motivation, leadership style, work environment, employee loyalty and commitment.

Abstract

ABSTRACTChoco chips are chocolate in the form of small granules, usually chocolate chips are used as decoration on cakes, pastries and so on. Generally, chocolate chips are only used as a snack and contain high levels of sugar. This research discusses how to consume chocochip snacks which have low sugar content and are safe for diabetes sufferers. The independent variables used in this research are the types of sugar in the form of palm, regular and tropical as well as the types of wheat and oat flour. This research was carried out by making dry cakes first with various variations of sugar and flour. After that, tests are carried out in the form of water, protein, carbohydrate, free fatty acid content and organoleptic tests. From the research results, it was found that the lowest content test was a sample of wheat flour with a variation of tropical sugar of 4.1%, while the chocochip cake with the highest water content was a sample of oat flour with a variation of palm sugar with a water content of 6.36%. In the protein content test, the chocochip cake with the lowest protein content was a sample of oat flour with a variety of tropical sugar with a protein content of 101.06 mg/L, while the chocochip cake with the highest protein content was a sample of wheat flour with a variety of tropical sugar with a protein content of 204 .51 mg/L. In the carbohydrate content test, the chocochip cake with the lowest carbohydrate content was a sample of wheat flour with a variety of regular sugar with a carbohydrate content of 60.17 mg/L, while the chocochip cake with the highest carbohydrate content was a sample of oat flour with a variety of regular sugar with a carbohydrate content of 109.22 mg/L. In the free fatty acid content test, the chocochip cake with the lowest free fatty acid content was a sample of wheat flour with a variety of regular sugar with a free fatty acid content of 1.01%, while the chocochip cake with the highest free fatty acid content was a sample of oat flour with a variety of sugar. sugar palm with a free fatty acid content of 1.69%. In the organoleptic test for panelists, the choco chip cake with the highest average score was in the sample with variations of oat flour and palm sugar. Key words : antidiabetes, chocolate chips, cookies

Abstract

Corrosion problems that often occur cause various damages and losses. The coating process has the advantage of being able to protect the metal surface from environmental influences that result in corrosion of the metal. The innovation of combining Polyurethane with Bentonite-Chitosan filler is able to make the polymer have better corrosion resistance. This study aims to see the effect of mixing between Polyurethane and Bentonite-Chitosan filler. The sample formulation used is polyurethane with variations of bentonite and chitosan 1%, 3%, 5%, 7%, 9%. The addition of Bentonite-chitosan filler affects the mechanical properties of the material. Characterization with the addition of Bentonite and Chitosan produces a polymer that has good thermal stability and good corrosion resistance. Test result Fourier Transform Infrared(FT-IR) there are functional groups NH, CH, C=O. Based on test resultsThermogravimetric Analysis(TGA) samplePolyurethane with modified bentonite 9%/chitosan 9% w/w has the best thermal stability among other samples where the sample starts to degrade (on set) at 419.22(oC) and stops degrading (end set ) at 521.94 (oC) with a weight loss of -31.156%. Polyurethane samples with 1% bentonite/chitosan 9% w/w modification had lower thermal stability where the sample started to degrade (onset) 312.21 (oC) and stopped degrading (end set) at 391.09 (oC) with a weight loss of -55.729 %. The results of the morphological test using the SEM tool show that the chitosan chains dispersed well into the bentonite interlayer. The corrosion test showed that the addition of bentonite and chitosan affected the corrosion rate, the greater the composition of bentonite and chitosan, the lower the corrosion rates. the best sample with a ratio of Polyurethane/Bentonite/Chitosan 9:9% w/w experienced the smallest corrosion rate of 5.08mpy and a mass loss of 0.1 gram.Keywords: Biodegradable, Corrosion, Polyurethane, Bentonite, Chitosan

Abstract

ABSTRACTPolyurethanes are generally made from petroleum-based polyols, but the current state of petroleum is depleting. The availability of petroleum, which is currently decreasing, encourages other parties to look for new alternatives. One alternative that can be used is palm oil. Technological developments that continue to increase are now also a reference for the development of antibacterial polyurethane coating paints which are carried out by adding another filler, namely chitosan. This study aims to determine the effect of variations in the weight of chitosan as an antibacterial agent and to determine the effect of the ratio of polyol and TDI on the quality of the paint analyzed through functional group analysis with Fourier Transform Infra Red (FTIR), morphological analysis of Surface Scanning Electron Microscopy (SEM), Heat resistance test with Thermo Gravimetry Analyzer (TGA), and Bacterial activity test. The analysis process was carried out with variations in the weight of chitosan (0; 2; 3; 4; 5; 6) % w/w and variations in the ratio of polyol and TDI (50:50) %; (40:60)%; (45:55)%. The test results showed that the best polyurethane paint was the variation in the ratio of polyol and TDI 50:50% with 6%w/w chitosan filling. This is because the more chitosan added, the better it will be in inhibiting bacterial activity, and the more polyols, the better the paint quality. The test results showed that the best polyurethane paint was the variation in the ratio of polyol and TDI 50:50% with 6%w/w chitosan filling.
