Published: February 2021

Abstract
Using a sample of 26 participants, we asked the students to prepare a text in written self-description at the end of the final path presentation in the sixth semester. One interesting thing is the relationship between personality differences and the types of words that people use. Recent studies covers an observing the relationship between personal qualities and the use of language in creating self-description. Text files are organized for transcription LIWC analysis to calculate the percentage of clout, authentic, and drives that student’s use. The results supported this possibility: LIWC’s clout, authentic, and drives dictionaries can be used as indicators of the student’s prevailing, confidence, motives and needs, we found that when calculated on written text, LIWC scores were connected with language dimension and psychology issues. These findings recommend that LIWC clout, authentic, motives, and needs dictionaries possibly will catch self-reported subjective emotion experience when applied to everyday activities. To enrich students’ confidence, power, motives, and needs toward the psychology issues faced by the students, students should be stimulated to discover the field of psychological processes and linguistic patterns by detecting their emotional and perceptual experiences.

Abstract
In this research, composite polyvinyl chloride ultrafiltration (PVC-UF) membrane was used for peat water treatment. The UF membrane was prepared by mixing polyvinyl chloride (PVC), polyethylene glycol (PEG400), ZnO, acetone, and N-dimethylacetamide (DMAC). The concentration of PVC was varied from 10 to 14 wt.%, while the PEG400 was varied from 0 to 15 wt.%. The concentration of acetone and ZnO was fixed at four (4) wt.% and two (2) wt.%, respectively. Immersion precipitation method was used to form the membrane structure. The experimental results showed that higher humic substance rejection (>50%) was achieved when 12 wt.% PVC and 10% wt.% PEG was added into the polymer solution. The permeate flux of the membrane was above 100 L/m−2h−1.Higher rejection of humic substances was obtained at an operating pressure of 30 psig.

Abstract
The electricity crisis can hamper various community or industrial activities. Meanwhile, the magnetic field with a high field strength around the wire and along the power line wire that is passed through a large electric current can be used as a new source of electricity with considerable power. For this reason, efforts are needed to utilize the magnetic field to offer an energy crisis solution. This research applies the magnet-electric law to the toroid core transformer to become a power plant. The simulation is carried out on a toroid transformer with an outer diameter of 11cm, 2.5cm thick, 9cm long which is mounted on a 27A current; 220V or 380V 3Ø. The result can be to turn on a 5W-160V or 10W-65V incandescent or 7W-200V LHE lamps. The value of 27A on the wire does not change due to the utilization of the magnetic field around the electric wire. From the analysis of a linear approach to power lines with larger currents up to several kA, a power of several kW can be generated at 220V. To get more power at a voltage of 220V required more toroidal transformers placed along the power line.
