The increase in the number of road construction projects has led to an increase in the need for road pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year of asphalt, as well as aggregate. Seeing these conditions, it is necessary to anticipate the use of waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used as aggregate and Asbuton (Buton Island rock asphalt) was used as a binder for the asphalt mixture. As an effort to save energy, the stirring system is cold. Based on the volumetric characteristics of the artificial coarse aggregate, it only meets the specifications for the VMA value, while the VIM and VFB values have not been met. The mechanical properties (stability and flow values) of the cold asphalt mixture on the replacement of natural aggregate with 25% artificial aggregate met the requirements, but did not meet the Marshall Quotien requirements

Published: June 2023

This research aims to evaluate students' sustainability awareness and engagement and to analyze students' perception of the ESD Project in Biology lessons at an Indonesian Senior High School. This study uses a Mixed Method research design combining quantitative and qualitative research methods. The participants were Year X students of a Senior High School in Jakarta in the 2022/2023 academic year. Survey, journal of reflection, semi-structured interview, observations, and documentation, were used to collect data. Finding: This research found that ESD Project in biology lessons develops Indonesian students' sustainability awareness and engagement. Students change their mindset from being unconscious to become more concerned with environmental issues. Several evidence of the consciousness in this research includes applying sustainability in the daily practice, doing real action by creating campaign videos. The awareness is also shown by their beliefs, values, and judgments in their reflective journal, including developing environmental literacy, changing into pro-environment, and positive attitude to protect the environment. Secondly, PjBL learning model in Biology lessons is meaningful for students by stimulating their cognitive and behavioral engagement. The most popular activity of the ESD Project is creating the design of clothes from waste. The implementation of ESD Projects has some challenges such as time consuming, and low self-regulation among Indonesian high school students. Implications for research, practice, and policy are discussed.

This study aims to identify online learning readiness (KBO) students of FKIP University of Mataram. This type of research is quantitative with a descriptive approach. The study used a KBO questionnaire instrument which was compiled with a scoring system. Analysis of the data used is the Pearson product moment correlation to see the correlation between KBO scores and academic abilities possessed by students. The results showed that students' online learning readiness (KBO) was at a score of less than 80, meaning that students' online learning readiness was still not very good. Meanwhile, according to the Pearson product moment correlation data analysis, it shows that the student correlation value from JIP is 0.815. For students from JMIPA it is 0.10. Meanwhile, students from JPBI and JIPS got a correlation value of 0.386 and 0.59. Based on these data, it can be concluded that JIP and JIPS students have a strong correlation between academic ability and students' KBO scores. While JMIPA and JPBI, students' academic ability and KBO scores have a low level of correlation.

Published: June 2023

Purple yam tuber is known to contain a lot of bioactive components useful for human health. This study was conducted to utilize the tuber in form of purple yam flour for crackers processing and to understand the effect of purple yam flour concentration on the characteristics of crackers.  A completely randomized design was applied using several concentrations of purple yam flour (0, 10%, 20%, 30%, 40%, and 50%) and 3 replications. The concentration of purple yam flour affects volume expansion, color values (L*, a*, and b*) and anthocyanin content of the crackers, but did not affect its water content and texture. The higher concentration of purple yam flour decreased volume expansion, L*, b*, and overall acceptance of the crackers, but increased the anthocyanin content and a* values.  This research proposes that 30% purple yam flour shall be applied to partly substitute wheat flour in crackers processing.  At this concentration, crackers were accepted by the panelist (like it slightly) and has hardness value 287.2 gF, L* 70.35, a* 11.12, b* 20.18, 2.5% water, and anthocyanin content 179.6 mg cyanidin3-glucoside equivalent/g.

This study aims to obtain information about students' critical thinking skills (CTS) through the application of the project based learning (PjBL) model on reaction rate material in the context of making liquid organic fertilizer (LOF) from bamboo shoots. The method used is an experimental method with a one-group pretest-posttest design. This study uses one class with a total of 27 students. The instruments used were observation sheets on the implementation of learning and tests of critical thinking skills which consisted of 15 multiple-choice questions. Test result data were processed using the N-gain test and paired sample t-test. The results showed that the application of the PjBL model in the context of making LOF from bamboo shoots obtained a learning implementation percentage of 85.4 and was included in the very good category. In addition, the CTS of students as a whole experienced an increase of 0.69 in the moderate category. The results of the paired sample t-test show that the significance value obtained is 0.000 <0.05 so it can be concluded that there is an increase in the CTS of students through learning.
Impact of Electrode Rotation on Aluminum GMAW Bead Shape
Authors:   American Welding Society, HANSEN JIM , HARWIG DENNIS D.
Published: June 2023

Aluminum gas metal arc welding (GMAW) uses inert shielding gas to minimize weld pool oxidation and reduce susceptibility to porosity and incomplete fusion defects. For aluminum shipbuilding, naval welding requirements highly recommend the use of helium-argon mixtures or pure helium shielding gas to provide a broader heat field and better weld toe fusion. Pure argon shielding gas can be used but has been susceptible to incomplete fusion and porosity defects, where argon’s lower thermal conductivity promotes a narrower arc heat field and shallow weld fusion depth. Using helium is a concern because it is a finite resource that costs approximately five times more than argon. The rotating electrode pulsed GMAW process was investigated to improve argon shielding fusion characteristics and reduce helium usage. Argon-shielded bead-on-plate tests were used to evaluate the relationship between ER5183 electrode rotation parameters and arc power on constant deposit area bead shape. These tests were compared to stringer beads (no oscillation) that were made with argon, helium, and helium-argon shielding gases. Electrode rotation improved underbead fusion depth width and toe fusion. With preferred rotation parameters, the bead width and incomplete fusion at weld toes were equivalent to helium-based welds. For weld reinforcement, electrode rotation promoted a nonsymmetric profile with deposit bias on the bead side, where rotation direction was aligned with travel direction. The bead-side deposit bias is an advantage based on preliminary horizontal V-groove welding procedures using ceramic backing. Electrode rotation can offset the effects of gravity, promoting a smoother bead and fusion profile.
