Abstract

Abstract The ELF (Extremely Low Frequency) magnetic field is a spectrum of electromagneticwaves that located at frequencies less than 300 Hz and classified as non ionizingradiation. The ELF magnetic field is utilized in many case, one of them in the case offood, it is because the magnetic field can be applied to inactivate pathogenicmicroorganisms that cause food easily damaged or rotten. One of the factors in food thatcan be a reference related to microbial growth is pH (Hydrogen potential). This studyaims to determine the effect of ELF magnetic field exposure in the preservation of milkfishto the pH value. This study involved 21 samples of fresh milkfish, with the selection ofcontrol and experiment class. The experimental sample was exposed to an ELF magneticfield with an intensity of 730.56 μT and 877.37 μT with exposure time of 2 x 30 and 2 x45 minutes. pH measurement using pH meter. The result of this research is ELF magneticfield exposure affects the pH value of milkfish, which can inhibit the increment of pHvalue. The effective dose in inhibiting pH value is ELF magnetic field exposure with730.56 μT during 2 x 30 minutes. Keywords: Magnetic Field Extremely Low Frequency (ELF), Preservation, Milkfish

Abstract

In this modern era, the utilization of Extremely Low Frequency (ELF) magnetic field on variety of technology is increased. This increase occurs in variety of technology like food, health, industry, communications and agriculture. One of the food that can be cultivated through the agricultural sector is ear mushroom (Auricularia auricular). This studies are aims to investigate the influence of magnetic field on ear mushroom with intensities, 100 μT, 300 μT, and 600 μT with long exposure of 10 minutes, 30 minutes, 50 minutes, and 70 minutes and determining the effective dose for the growth of heat pin mushroom. This study was using completely randomized design with one primary factor and three replications. The result showed that the magnetic field produces results fairly significant increase in heat pin mushroom growth. Result in each of the experimental class increased by the rise of magnetic field intensities with lowest growth of heat pin getting by 600 μT for 70 minute, and the day of coming up heat pin on 22,33 Hsi and highest growth of heat pin getting by control class with the day of coming up heat pin on 24,44 Hsi.

Abstract

Most people are often doing indoor activities that they demand indoor comfort to carry out better, calmer, and comfortable activities. This study aims to assess the change of room temperature towards time in Building 3 FKIP Jember University. The research was conducted in lecture room number 35C 201, 35B 203, 35B 101, and 35E 105Building 3 FKIP Jember University. The method used was adescriptive method. Data was analyzed using One-Way Anova using SPSS 22. The results of this study indicate that the ambient temperature in the room changes by time, in general it appears that the room temperatureat 06.00 until 17.00 had a p-value (significance) <0.05, which means there is a significant temperature difference. However, there are several variables that had a p-value (significance) ≥ 0.05 that means no significant temperature difference. The average temperature measurement shows that the highest average is in room 35C 201 (28,445oC), while the lowest is in 35E 105 (27,8oC). The average temperature of the four rooms scored above optimal comfort scale, which is 28.1oC, or higher. The lowest average temperature is obtained at 06.00 WIB with 26oC and the highest average is at 13.00 that reached 29,525oC Keywords: Thermal Comfort, Effective Temperature, Lecture Room

Abstract

The aim of this research is to study the effect of guided discovery learning model on critical thinking skills and motivation of students on learning materials elasticity and Hooke law. Learning physics in the classroom tends to be monotonous and less attractive where students are not involved directly in the find a concept, so that the students have not been motivated to active in learning. The effect critical thinking skills of students is low, because students did not experience their own facts that happened. This research is an experimental research. This research was conducted at SMAN 1 Jenggawah. The data are collected by test, questionnaire, interview, and documentation. To examine the hypothesis, this research used independent sample t-test with SPSS 22 version. According to independent sample t-test analysis in the critical thinking skills showed sig value (2-tailed) is 0,000 or < 0,05 then Ho is rejected, and for the motivation of student’s showed sig value (2-tailed) is 0,000 or < 0,05 then Ho is rejected. In conclusion, the guided discovery learning model has a significance influential to critical thinking skills and motivation of students on learning materials elasticity and Hooke law in Senior High School 1 Jenggawah
