Published: August 2024

Coal mining will form acid mine drainage in former open pit mines. If acid mine water enters community waters, it will cause disturbance to biota and decrease water quality. Sawahlunto is one of the cities in Indonesia that has a coal mining area located near a settlement. With the acid mine drainage, if it rains, the water will flow into the river where the water is used by the community. Part of the coal is used as fuel for the Sijantang Sawahlunto PLTU. The fuel also produces waste in the form of combustion ash known as fly ash and bottom ash (FABA). This study uses FABA to neutralize acid mine water to meet the community's irrigation water needs. This research will determine the appropriate mass of FABA in neutralizing acid mine drainage. Acid mine water comes from the former mining pit of PT. High Guguak Coal with a pH of 2.88. Then the acid sample is brought to the laboratory to be mixed with FABA and lime. 4.98 grams of FABA with 0.02 lime can neutralize 200 mL of acid mine drainage and change the pH from 2.88 to 7.91. FABA can be included in the settling pond to neutralize acidic water before it is released into community waters.

Published: August 2024

Climate change in the 21st century has become the primary concern of all the countries' leaders, including Indonesia. In education, learning related to climate change needs special attention not only on the knowledge aspect but also on the attitudes and behavior of students. East Kalimantan is one of the provinces in Indonesia, and the Indonesian government does expect it to be the new nation's capital. This research is descriptive analysis research. This research aims to determine students' level of climate literacy in aspects of basic knowledge, attitudes, and behavior. The survey does conduct on 240 students of grade 12th students from eight different schools in East Kalimantan, Indonesia. The sampling technique is stratified random sampling. The research instrument used was a questionnaire divided into three aspects: basic knowledge, attitudes, and behavior. In the basic knowledge aspect, the questionnaire consists of 15 questions with a Guttman scale (true-false). Each questionnaire consists of 10 statements with a Likert scale in attitude and behavior. The results showed that students' level of climate literacy in the basic knowledge aspect was only in the sufficient category, and the attitude and behavior aspects were in the high category. Although, in general, the level of student climate literacy in the aspects of attitude and behavior is in the high category, there are still some students classified at the low level. We conclude that students' climate literacy still needs to be improved in terms of basic knowledge and aspects of attitude and behavior to prevent the future negative impacts of climate change.

The results show that the modified Hawking temperature produces non-linear corrections that show the interaction between black holes and the quantum structure of spacetime. graphical representations visualize the variation of Hawking temperature with changes in area, electric charge, angular momentum, and cosmological parameters. The implications of the research extend to the understanding of the thermal properties of black holes in the context of gravitational and quantum theories. The research identifies gaps in the knowledge of the effects of cosmological parameters on black hole thermodynamics and introduces Hawking temperature modifications that have not been mapped in detail before. The study concludes that the Hawking temperature modification provides a strong foundation for further research in black hole physics, particularly in the effect of physical and cosmological parameters on the thermal properties of black holes.

This empirical investigation delves into the application of blended learning within project-based instruction (project-based blended learning), within the framework of physics education for eleventh-grade students in a high school setting. The primary aim is to unravel the repercussions of this teaching model on the students' proficiency in scientific argumentation, particularly in the domain of optical instruments. Employing the non-equivalent control group design, the study enlists two classes: the experimental and the control group at a senior high school in Bandar Lampung, Indonesia, encompassing a total of 60 students during the academic year 2022/2023. Quantitative evaluation of scientific argumentation skills was conducted through tests, while qualitative insights into student reactions were garnered via an open-ended questionnaire. The findings underscore a noteworthy enhancement in the scientific argumentation abilities of the experimental group (n-gain: 0.69) as opposed to the control group (n-gain: 0.40), with the test of mean differences yielding a significance level (2-tailed) of 0.00. Qualitative scrutiny of the data also brought to light a more pronounced positive reception from students in the experimental cohort, lending support to the potential refinement of the project-based blended learning model for the augmentation of students' scientific argumentation aptitude.
