Abstract

The research was motivated by the high turnover rate of employees in companies. The aim ofthis research is to determine the effect of training satisfaction and psychologicalempowerment on turnover intention with work involvement as a mediating factor. Thisresearch is quantitative research. With this type of explanatory survey research, the samplingtechnique was nonprobability sampling, as many as 73 employees from PT. Indo Metro SuryaAndola. As a measuring tool, an 80-item questionnaire was used with Likert scalemeasurements and analyzed using Path Analysis. The research results show that trainingsatisfaction has a negative effect on employee turnover intentions. Psychologicalempowerment has a negative effect on employee turnover intentions. Training satisfaction hasa positive effect on employee turnover intentions. Psychological empowerment has a positiveeffect on employee turnover intentions. Training satisfaction has a negative effect onemployee turnover intention, mediated by employee work engagement. Psychologicalempowerment has a negative effect on employee turnover intention, mediated by employeework engagement.

Metode: Penelitian ini menggunakan metode observasi/ survei analitik dan menggunakan pendekatan cross-sectional. Variabel independen yang digunakan dalam penelitian ini yaitu plasenta previa, konsumsi kafein, kadar Hb sedangkan variabel dependennya yaitu kejadian BBLR. Teknik sampling dalam penelitian ini menggunakan total sampling dimana kriteria populasinya yaitu ibu bersalin yang melahirkan, dengan jumalah sampel sebanyak 115 responden.  Uji analisis data menggunakkan analisis univariat dan analisis bivariat dengan uji chi-square. Hasil: Berdasarkan hasil analisis univariat menunjukkan frekuensi BBLR 67 (58,3%), plasenta previa 35 (30,4%), konsumsi kafein 84 (73%), dan anemia 89 (77,4%). Hasil analisis bivariat menunjukkan plasenta previa dengan BBLR p-value 0,01 dan OR 5,342. Kadar Hb dengan BBLR p-value 0,03 dan OR 4,425. Konsumsi kafein dengan BBLR p-value 0,01 dan OR 4,118. Kesimpulan: Ada hubungan antara plasenta previa, konsumsi kafein, kadar Hb dengan kejadian BBLR.

Abstract

Wordwall web media is one of the varied learning media that displays text information, still or motion pictures, animations, sounds, and videos that are fun for students in the form of games/quiz. This research is based on the fact that in PAI learning the teacher still has not maximized the use of media, so that the student learning process is sometimes less conducive. The purpose of this study was to find out whether the application of this wordwall web media could improve PAI learning outcomes for students at SMP Negeri 2 Langsa. This research is a Classroom Action Research (CAR) which consists of two cycles, the data is taken through data collection techniques in the form of data from observing student activities during the learning process using web wordwall media, student learning outcomes and also interviews. The data that has been collected is then processed with qualitative data analysis. The result of this research is that there is an increase in PAI learning outcomes through the application of web wordwall media at SMP Negeri 2 Langsa. This can be seen from the achievement of students' KKM scores and the percentage that has increased in learning outcomes shown in the first cycle of 67% and an increase in the second cycle to 86%. So the increase in student learning outcomes in learning wordwall web media is said to be successful.

Abstract

This study aims to find out whether students' understanding of mathematical concepts after applying the discovery learning model is better than before applying the discovery learning model. This type of research is Pre Experimental Design research with its design form: One-Group Pre-test & Post-test. The study population is Class XI students of SMA PGRI 2 Padang for the 2023/2024 academic year consisting of 2 classes. The sampling technique is carried out (Purposive Sampling). The instruments used in this study were pre-test and post-test in the form of essays. The test statistics used for hypothesis testing are the Paired Sample T-Test. The results of the hypothesis test were obtained = 13.711 and = 2.060. Because is greater than , the is rejected with a real rate of 0.05 and means that the hypothesis is accepted. So it can be concluded that students' understanding of mathematical concepts by applying the discovery learning model is better than before applying the discovery learning model

Abstract

There is a growing interest to convert biomass waste such as corn cob to biofuel. Thermal conversion such as pyrolisis may play an important role to produce bio-oil. The objective of this research was to develop a kinetic study of catalytic pyrolysis of corn cob over Fe-Ni/Char catalyst using Thermogravimetric Analysis (TGA). The solid catalyst was prepared by impregnation method. The ratio of the percentages of Fe and Ni metals in the X-Ray Fluorescence (XRF) analysis of the catalyst was close to 1:1, resulting in metal loading values of 2.5% (1.062% and 1.013%), 5% (2.291% and 2.794%), and 10% (4.947% and 5.417%) for the catalyst. The pyrolysis experiments were performed using various catalyst loadings of 0, 2.5, 5, and 10%. In addition, the present study also investigated the influence of heating rates of 5, 10, and 20 K min-1. Two isoconversion models, Kissinger-Akahira-Sunose (KAS) and Ozawa-Flynn-Wall (OFW) were utilized to determine the activation energies. The activation energies calculated using the KAS and OFW models revealed a consistent trend, with values of activation energy of corn cob pyrolysis around 124 - 303 kJ/mol and 133 - 313 kJ/mol, respectively.

Abstract

Background: Sugarcane (Saccharum officinarum L.) serves as a valuable resource for the sugar and beverage industries, a significant quantity of its by-product, bagasse, remains underutilized. A promising strategy for increasing the value of bagasse involves improving its substrate quality through the application of cellulose-degrading bacteria, such as Bacillus subtilis. Methods: The objective of this research is to investigate the influence of bagasse degradant supplementation on the growth of oyster mushrooms. A randomized experimental design was employed to evaluate growth media containing varying concentrations of bagasse degradant (500, 600, 700, and 800 gram) in comparison to a control group. The study assessed the impact of bagasse degradant on pin diameter, fresh weight, dry weight, and water content, using ANOVA and the Duncan's Multiple Range Test (DMRT) at a significance level of 5%. Results: The study showed the addition of bagasse degradant affected the pin diameter, fresh weight, and dry weight of oyster mushroom. However, it is not effective towards the water content of oyster mushroom. Conclusion: The addition of bagasse degradant affected the pin diameter, fresh weight, and dry weight, whereas the water composition did not affected the growth of P. ostreatu
