    Telah dilakukan sintesa lapisan tipis MgTiO3 dengan menggunakan metode Sol Gel. Lapisan tipis MgTiO3 dibuat dengan mencampurkan TiO dan MgSO4 sebagai prekursor. Larutan ini kemudian diaduk selama 1 jam agar campuran menjadi homogen dengan menggunakan magnetic stirrer. Lapisan tipis MgTiO3 dipanaskan dengan variasi suhu mulai dari 300, 400, 500 dan 60oC selama 1 jam. Berdasarkan hasil pengujian XRD menunjukkan bahwa pada suhu 300 - 500oC nilai ukuran butir kristal semakin besar, sementara pada suhu 600oC ukuran butir kristal mengecil. Struktur kristal yang terbentuk dari lapisan tipis MgTiO3 adalah rutil. Hasil SEM menunjukkan lapisan MgTiO3 terdeposisi dengan baik yang ditunjukkan dengan tidak munculnya retakan pada permukaan lapisan serta terdapat adanya pori yang terbentuk dan ketebalan lapisan tipis MgTiO3 berkisar antara 1,67 – 1,79 µm. Hasil pengujian UV-Vis menunjukkan suhu pemanasan mempengaruhi turunnya nilai band gap. Semakin tinggi suhu pemanasan semakin kecil band gap yang dihasilkan, yaitu pada suhu 300oC bernilai 3,22 eV dan pada suhu 600oC bernilai 3,02 eV. MgTiO3 thin films synthesis has been done using Sol Gel method. The MgTiO3 thin films is made by mixing TiO and MgSO4 as precursors. This solution is then stirred for 1 h to have homogeneous mixture by using a magnetic stirrer. The MgTiO3 thin films is heated with temperature variations range of 300, 400, 500 and 600°C for 1 h. Based on XRD test showed that at 300 - 500 oC value of crystalline grain size was increased, while at 600oC the size of crystal grains decreased. The crystalline structure formed from a thin films of MgTiO3 is rutile. The SEM results show a well-deposited MgTiO3 films which is indicated by the absence of cracks on the surface of the coating and there is a pore formed and the thickness of the MgTiO3 thin films range of 1.67 to 1.79 μm. UV-Vis test show that the heating temperature affects the decrease in band gap value. The higher the heating temperature give the smallerof band gap, ie at a temperature of 300oC worth 3.22 eV and at a temperature of 600oC worth 3.02 eV, respectively.

    The formulation of this problem is the work environment and motivation. Towards job satisfaction The research model used is a descriptive research model which describes systematically and accurately the factors studied. The data testing technique used in this study includes a validity test with a calculated r value and a reliability test with a Cronbach's Alpha value, the data analysis used is multiple linear regression to test and prove the research hypothesis. The research method carried out by the author is in the form of data collection, processing data, analyzing data and presenting data so that the results presented by this author are scientific and accountable. By using correlation coefficient analysis, it is known that the influence of work environment and motivation on job satisfaction. The regression coefficient of the work environment variable (b1) is 0.521. This means that if the value of X1 (work environment) has increased by 1 unit, assuming the other dependent variables are fixed, then the level of variable Y (Job Satisfaction) will increase by 0.521. and every increase or decrease in motivation by 1 point, then the job satisfaction of employees at PT. Relazindo Usaha Bersama will increase or decrease by 0.403. And vice versa if the value of X1 decreases, while the variable X2 remains, the level of variable Y will decrease. From the results of multiple linear regression analysis Y = 13,532 + 0.521 X1 + 0.173 X2, meaning that every increase or decrease in the Work Environment by 1 point, then the job satisfaction of employees at will increase or decrease by Based on the results of hypothesis testing, it is obtained that F count to determine the Work Environment and Motivation is 0.000 and 0.000 or the probability is below 0.05 then it meets the criteria which means Ho is rejected and Ha is accepted or the regression coefficient is significant or Work Environment and Motivation has a significant effect on job satisfaction. From the results of the F test, model 1 obtained a value of 181,711 and model 2 obtained a value of 100,757 where the value is greater than the F table of 3.09, then H0 is rejected and Ha is accepted. From the results of the t test, the t count of the work environment is 7.555, and the t count of motivation is 2.755, where the value is greater than the t table of 1.66055, then H0 is rejected and Ha is accepted, meaning that there is a significant relationship between the work environment and motivation towards job satisfactio

    Comparison of Geographically Weighted Regression with Adaptive Gaussian and Bisquare Kernel on Open Unemployment Rate in Riau Islands

    No full text
    Regression analysis is an analysis to determine the relationship and influence of independent variables on the dependent variable. If the data has a spatial relationship, this analysis has the potential to produce a less accurate model because the regression analysis ignores the influence of the location. One of the data indicated to have a spatial relationship is the open unemployment rate. One spatial analysis that can be used to accommodate spatial relationships is the Geographically Weighted Regression (GWR) model. In the GWR model, a spatial weighting matrix is required whose size depends on the proximity between locations. In this study, two spatial weighting matrix were used: Adaptive Gaussian Kernel and Adaptive Bisquare Kernel. Based on the results of the analysis, it is known that the factors influencing the open unemployment rate in the Riau Islands in 2024 at several locations are the human development index, Economic Growth, and Minimum Wages by Regency/City. Based on the R2 value and AIC value, the best spatial weight matrix produced is the Adaptive Bisquare Kernel weighting function with an R2 value of 93.32% and an AIC value of 15.2835

    Material komposit yang diperkuat dengan serat merupakan material rekayasa teknik yang saat ini banyak digunakan karena memiliki kekuatan dan kekakuan spesifik yang lebih baik daripada material teknik. Serat alam merupakan pilihan alternatif sebagai penguat komposit karena serat alam merupakan material komposit yang ramah lingkungan dan bisa didaur ulang. Selain memiliki nilai ekonomis yang tinggi, limbah ampas tebu sangat mudah didapat, murah, tidak membahayakan kesehatan, dan dapat terdegradasi secara alami (biodegradability) sehingga nantinya dapat dimanfaatkan sebagai serat penguat komposit mampu mengatasi permasalahan lingkungan. Tujuan penelitian ini adalah untuk mengetahui pengaruh (komposisi/persentase/kandungan) serat ampas tebu terhadap penyerapan suara panel akustik. Panel akustik dibuat dengan mencampurkan serat ampas tebu, semen, dan air. Variasi (komposisi/ persentase/kandungan) serat ampas tebu dimulai dari 2% sampai 10%. Untuk uji karakteristik penyerapan suara dilakukan dengan menggunakan metode ruang dengung berdasarkan ISO-354 (1985), dengan sumber suara white noise. Hasil penelitian menunjukkan bahwa semakin tinggi komposisi serat ampas tebu, semakin tinggi pula nilai koefisien penyerapan suara dari panel tersebut. Serapan suara terbaik dengan nilai koefisien penyerapan 0,4 terjadi pada panel dengan persentase serat ampas tebu 10%, menggunakan sumber suara  white noise

    Aims: to revisited the importance of citing the sources properly, discusses the noble human values regarding citation and simple example of citation in the context of academic writing Discussion: The importance of citations in academic writing offer clear and convincing evidence which build on arguments and facts asserted carefully by authors in their academic writing. Beside of that, a well-organized cited text-section also a conclusive evidence of acknowledges the endeavor and hard work of previous scholars who had struggling published his/her work which is now being quoted. Citations in academic writing are treasure references to all the sources an author has used to support his/her own ideas and then carefully referred to during his/her writing on a manuscript. authors have the obligation to supply references to all the published/unpublished works they reviewed and used. The cited works can include books, research papers, websites, and other internet sources that writers ascribe to using certain citation styles/format. Actually, there are differences in citation styles (APA, MLA, etc.) and their relevance in different academic contexts literally make scholars and readers become more integrated in context. By citing properly, it highlights a true noble human values such as honesty, resilience, hard work, humility, gratitude, credibility, integrity, open-mindedness and obedience. This approach reveals an author’s academic expertise, render rationality to a text and honor intellectual honesty. In other words, citations carry critical significance in academic writing. The challenges or common pitfalls associated with improper citation can be in the form of inappropriate misused of citing, which further slowing actual progress in research and circulating unsupported beliefs. For academic writers, it is essential to understand the grounds for this significance. Conclusion: Citing the sources properly will help the author, the reader, the editors and the peer reviewer and in the end, the entire scientific community reinforces a responsibility for ensuring that the customs, traditions, and ethical standards that guide the whole process of accountable and reliable academic writing products.
