The purpose of this study was to investigate the problem-solving skills (PSS) and chemistry learning experiences (LE) of teacher candidates. 191 pre-service chemistry teacher (130 women, 61 men) were taken as the research sample using the purposive random sampling technique. The research design used a cross-sectional survey with focus group interviews. The quantitative data obtained were analyzed using the MANOVA test and while the interview data using the Patton analysis technique. The research findings show that: 1) the level of the chemistry learning experience of pre-service chemistry teacher (LE) is higher than the ability of problem-solving skills (PSS); 2) the level of ability of female chemistry teacher candidates for PSS and LE was found to be higher than that of males; (3) there are differences in PSS and LE based on grades levels, but there is no difference based on gender; 4) there is a difference in PSS and LE between freshman, sophomore, and junior grades. The findings of the interview are relevant to the results of the survey which proved that male and female students both have positive attitudes towards chemistry, however, it was found that there were differences in PSS and LE between grade level (1stgrade, 2stgrade, 3st grade). Thus, it is suggested that the learning process in universities prioritizes the development of LE and PSS in chemistry learning so as to improve the soft skills and academic achievement of prospective chemistry teachers.

Landslides are disasters that occur due to the shifting of land. To detect it, we need a system that can monitor it in real-time. Therefore, in this study, a wireless data acquisition system based on the Xbee Pro S1 module was built for monitoring landslides so that the community quickly responded in the event of a disaster. Testing the range of the module is very important to ensure that data communication between the transmitter and receiver can take place. The test carried out in this study was to take the plate distance data on the extensometer by adding a load and then detected using an ultrasonic sensor. The Xbee transmitter sends data to the Xbee receiver in real-time. From the test results, the maximum range of the Xbee Pro S1 module is 150m outdoors with an average delivery time of 15s from the transmitter to the receiver

Publisher : Pascasarjana, Mataram University

This development research aims to develop an effective problem-based physics learning device model to improve students' generic science skills. The type of research used is Research and Development (R&D) using a 4D model. This 4D model consists of four stages, namely Define, Design, Develop and Disseminate. The effectiveness of the learning device was obtained based on the analysis of the observation sheet on the implementation of the lesson plans from three observers was then determined using the calculation of the Interjudge Agreement (IJA) and the N-Gain test. Based on the results of the research that has been carried out, the results of the IJA calculation analysis show that the implementation of learning is above 75% with the N-Gain test results of 0.54 are in the medium category, while the average value for the pretest value is 36.91 and the average posttest value 68.75. So it can be said that the problem based model of physics learning tools used is effective in improving the generic science skills of students

Damage to used cooking oil is caused by hydrolysis and oxidation processes, these reactions are formed due to the use of oil many times. In terms of physical damage occurred in the smell and color (brown oil, cloudy to blackish), chemical changes in the form of acid numbers and peroxide numbers are quite high. This study aims to determine (1) there is an effect of variations in the mass of the onion peel adsorbent on the physical properties of used cooking oil; (2) there is an effect of mass variation of onion peel adsorbent on the physical properties of used cooking oil; and (3) physicochemical properties of used cooking oil purified according to SNI 3741:2013. The research method uses an experimental research type with a quantitative approach. The study design used a completely randomized design (CRD). The data analysis technique used One Way ANOVA. The test parameters include odor test, color test, acid number test and peroxide number test. The adsorption temperature was constant at 70°C for 30 minutes, the mass variations of the onion peel adsorbent were 0 g (without onion skin), 5 g, 10 g, 15 g, and 20 g in 100 ml of used cooking oil. The results of the study of physical properties (smell and color), variations of 5 gr, 10 gr 15 gr and 20 gr produced "normal" odors, while variations of 10 gr, 15 gr and 20 gr color produced "normal". Furthermore, the chemical properties showed a decrease in the acid number after the purification process, the largest variation in the decrease in the acid number was in the 20 gr treatment as much as 74.56%, the largest decrease in the peroxide value in the 20 gr treatment as much as 90.63%.
