Abstract

Beton merupakan material yang sering digunakan dalam pembangunan struktur. Karena itu beton mengalami banyak pengembangan dan modifikasi, termasuk dalam hal campuran material beton. Selain untuk menghasilkan beton dengan mutu lebih baik, pengembangan campuran beton juga harus ramah lingkungan dan berkelanjutan. Maka dari itu, dilakukan penelitian dengan bahan tambah yang berasal dari alam. Dalam penelitian ini digunakan bahan tambah serat batang pisang batu dan superplasticizer Sikament LN. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi serat pisang dengan variasi komposisi serat. Serat pisang yang digunakan memiliki panjang 10 cm. Benda uji berbentuk silinder berdiameter 15 cm dan tinggi 30 cm. Benda uji adalah campuran serat pisang berdiameter 4 mm dan panjang 10 cm dengan variasi serat: 0,4 % (BU 1); 1.2 % (BU 2); dan 2% (BU 3) dan penambahan Sika sebesar 1,2% berat tiap benda uji. Dari hasilpengujian, didapat kuat tekan BU 1 sebesar 22,225 Mpa ,kuat tekan BU 2 sebesar 11,614 Mpa dan kuat tekan BU 3 sebesar 6,958 Mpa. Dari hasil pengujian kuat tekan didapat kesimpulan bahwa penambahan serat pisang mengurangi kuat tekan beton. Namun kuat tekan beton serat pisang dengan penambahan superplasticizer Sika masih lebih besar daripada pengujian tekan beton serat pisang terdahulu tanpa penambahan superplasticizer. Disamping itu, metode penambahan serat pisang juga mempengaruhi kekuatan tekan beton. Dari hasil trial mix design didapat bahwa penambahan serat pisang kering yang diikutipenambahan air, supeplasticizer Sika, semen dan agregat memberikan hasil kuat tekan beton paling besar. Kata Kunci : Beton, Serat Pisang,  Superplasticizer ABSTRACT Concrete is a material that is often used in the construction of structures. Therefore concrete undergoes a lot of development and modification, including in terms of concrete material mixture. In addition to producing better quality concrete, concrete mixture development must also be environmentally friendly and sustainable. Therefore, research is carried out with added materials derived from nature. In this study used material added fiber banana and superplasticizer Sikament LN. This study aims to find out the influence of banana fiber composition with variations in fiber composition. Banana fiber used has a length of 10 cm. Cylinder-shaped test object diameter 15 cm and height 30 cm. The test object is a mixture of banana fiber diameter of 4 mm and length of 10 cm with fiber variation: 0.4 % (BU 1); 1.2 % (BU 2); and 2% (BU 3) and the addition of Sika by 1.2% of the weight of each test object. From the test results, obtained a compressive strength BU 1 of 22,225 Mpa, BU 2 compressive strengthwas 11,614 Mpa and BU 3 compressive strengthwas 6,958 Mpa. From the results of compressive strength testing obtained the conclusion that the addition of banana fiber reduces the strength of compressive strength. However compressive strengthof banana fiber concrete with the addition of superplasticizer Sika is still greater than the previous banana fiber compressive strengthtesting without the addition of a superplasticizer. In addition, the method of adding banana fibers also affects the compressive strengthof concrete. From the results of the trial mix design was obtained that the addition of dried banana fibers followed by the addition of water, supeplasticizer Sika, cement and aggregates gave a greater compressive strength result. Keywords: Banana Fiber, Concrete, Superplasticizer

Abstract

In the business world, outsourcing is one of the strategies in providing services or materials to help the company's performance to stay focused on the main activities. Article 64 of Law Number 13 of 2003 concerning employment states that not all types of work can use outsourcing, including activities that are core to the company. After the enactment of Law Number 11 of 2020 concerning Job Creation, it removed this limitation which of course affected the quality and privacy of the company. In this study, the author will examine managerial supervision related to the quality of outsourcing workers' performance on user companies after the issuance of the Job Creation Act. This research uses empirical juridical research methods.From the results of the study that the user company must make a selection on the credibility of the company and the quality of the workforce to be employed as well as an agreement containing articles on supervision between the user company and the outsourced company.Keywords: Juridical Analysis, Managerial Supervision, Outsourcing, Job Creation Act.

Abstract

This research aims to determine the extent of the influence of marketing strategy and customer satisfaction on the sales volume of flower bouquets through service quality in Medan Tembung sub-district. The population in this study was the Hai Gallery Medan store customers, totaling 250 customers. The sampling technique uses the Slovin formula with an error tolerance of 5% and uses the Sample Random Sampling technique so that the total sample is 154 respondents. The analysis used is multiple linear regression. The results of this thesis show the influence of marketing strategy on sales volume with the result tcount 3.007 > ttable 0.1322 and significant 0.003 < 0.05, so marketing strategy has a partially significant effect on sales volume. The effect of customer satisfaction on sales volume with the results of tcount 8.645 > ttable 0.1322 and significant 0.000 <0.05, then customer satisfaction has a partially significant effect on sales volume. The influence of marketing strategy on service quality with the results of tcount 3.643 > ttable 0.1322 and significant 0.000 <0.05, then marketing strategy has a significant effect partially on service quality. The effect of customer satisfaction on service quality with the results of tcount 3.998 > ttable 0.1322 and significant 0.025 <0.05, then customer satisfaction has a partially significant effect on service quality. The effect of service quality on sales volume with the results of tcount 2.542 > ttable 0.1322 and significant 0.002 <0.05, then service quality has a partially significant effect on sales volume. The direct effect of marketing strategy on sales volume is 0.123, while the indirect effect is 0.053, so it can be concluded that the intervening variable, namely the service quality variable, is not able to mediate marketing strategy on sales volume. The direct effect of customer satisfaction on sales volume is 0.564, while the indirect effect is 0.020, so it can be concluded that the intervening variable, namely the service quality variable, is not able to mediate customer satisfaction on sales volume.

This study uses two dependent variables, namely rewards and sanctions, intervening variables, namely job satisfaction and independent variables, namely work motivation. The data in this study were collected through distributing questionnaires to 40 employees at the population and civil registration office of the city of Medan as a research sample. The sampling technique used is non-probability sampling. The data analysis method used is quantitative analysis, namely validity test, reliability test, classical assumption test consisting of normality test, multicollinearity test and heteroscedasticity test, multiple linear regression analysis, hypothesis testing consisting of t test, F test and R2 test. Based on data analysis, the results showed that the indicators in this study were valid and reliable. In the classical assumption test, the data is normally distributed, there is no heteroscedasticity and multicollinearity. In the hypothesis test in the t test it is known that the award variable has a significant effect on work motivation, the sanction variable also has a significant effect on work motivation. In the F test it is known that awards and sanctions jointly affect work motivation. In the R2 test it is known that the award variable has a significant effect on work motivation, the sanction variable also has a significant effect on work motivation. In the F test it is known that rewards and sanctions jointly affect work motivation. In the R2 test it is known that the magnitude of the effect of rewards and sanctions on job satisfaction is 63.6%. While the remaining 36.4% is influenced by other factors outside the award and sanction variables.
