Abstract

Technological developments have given birth to memes as a popular form of communication on social media. In addition to their entertainment function, memes often contain hate speech, insults, slander, and provocation that have the potential to violate the law and are classified as cybercrimes. This study aims to analyze the linguistic structure, meaning, and implied context in digital memes that have the potential to be criminal. The study uses a qualitative method with a forensic linguistic approach and critical discourse analysis. The research objects are memes circulating on social media in the period 2024-2025, selected based on indications of hate speech, defamation, or provocation according to the provisions of the ITE Law and the Criminal Code. The results show that memes often utilize linguistic ambiguity, irony, sarcasm, and metaphors to disguise the intent of insults or hatred that can trigger social conflict and legal consequences. Social cognitive analysis reveals the relationship between discourse structure, ideology, and power relations in digital society. In addition, syntactic-semantic-pragmatic analysis is able to reveal the spectrum of linguistic aggression in the digital space. This research provides a theoretical contribution to the development of forensic linguistics, as well as practical benefits for increasing digital literacy and legal awareness in the cyber era.

Abstract

Land degradation is a global challenge that threatens ecosystem productivity, food security, and climate resilience. Agroforestry is promoted as a multifunctional and adaptive land restoration approach to degraded landscapes. This study aims to analyze the role of agroforestry in degraded land restoration and its underlying ecological and socio-economic mechanisms. This study uses a systematic literature review with a thematic synthesis approach to reputable scientific articles and policy documents published in the period 2015-2025. The literature was selected based on the criteria of topic relevance, peer-reviewed status, and focus on the ecological and social impacts of agroforestry in the context of land restoration with a total of ±50 primary sources analyzed. The results of the study show three main findings. First, agroforestry consistently improves the quality of degraded land through improving the physical-chemical properties of soils, reducing erosion, and increasing carbon stocks. Second, the integration of agroforestry with Assisted Natural Regeneration (ANR) techniques has proven to be more effective and cost-effective in landscapes that still have natural regeneration potential. Third, the success of agroforestry is largely determined by institutional support, access to financing, and linkages to markets that strengthen the livelihoods of local communities. Based on these findings, this study recommends the integration of agroforestry-ANR in community-based restoration policies as well as the implementation of a long-term monitoring system to assess the sustainability of ecosystem services.

Abstract

Education in the 21st century demands learning processes that foster deep, meaningful understanding. Within the framework of the Merdeka Curriculum, deep learning is regarded as an essential approach to support students in developing critical thinking, reflective skills, and the ability to connect scientific concepts to real-life contexts. This study aims to describe teachers’ and students’ perceptions of the implementation of deep learning in physics instruction at SMAN 2 Lembang. A descriptive survey design was employed, integrating both qualitative and quantitative data. The data were collected through questionnaires, semi-structured interviews, classroom observations, and instructional documentation. Participants included physics teachers and eleventh-grade students. Data analysis followed the stages of reduction, presentation, and conclusion drawing. The findings reveal that teachers generally possess a solid understanding of deep learning principles, although various challenges persist in its implementation, such as limited instructional time, laboratory constraints, and students’ readiness for reflective and independent learning activities. Most students perceived that deep learning helped them achieve a deeper understanding of physics concepts, even though some still required guidance in exploratory and reflective tasks. Supporting factors included school policies that encourage innovation and teachers’ motivation to improve instructional practices, while inhibiting factors involved uneven learning facilities and differences in student preparedness. Overall, the study indicates that deep learning has the potential to enhance the quality of physics learning. However, its effective implementation requires continuous support through teacher training, improved instructional resources, and adaptive strategies aligned with the school context.

Abstract

This study aims to examine the effect of the Problem-Based Learning (PBL) model on students' conceptual understanding of environmental issues. This study used a quantitative approach with a pre-experimental one-group pretest-posttest design. The sample consisted of 30 ninth-grade D students at SMP Negeri 4 Tuban, selected using a purposive sampling technique. The instrument used was an essay test that measured students' conceptual understanding based on indicators including the ability to remember, understand, apply, analyze, evaluate, and generate new ideas. Data were analyzed using the N-gain test to assess changes in students' conceptual understanding. The results showed an increase in the average pre-test and post-test scores of 21.3, with an N-gain value of 0.55, which is considered moderate. This study has limitations because it was only conducted in a pilot class without involving a control class. Therefore, it is recommended that future research use a research design with a control group to increase external validity and broaden the generalizability of the research findings.

Abstract

This study aims to overcome the weaknesses of starch-based bioplastics by utilizing cellulose extracted from rice straw stalks. The increasing amount of conventional plastic waste that is difficult to decompose has created an urgent environmental problem, so that bioplastics have emerged as an environmentally friendly alternative. However, bioplastics from potato starch have low water resistance and less than optimal mechanical properties. Rice straw stalks were chosen because of their abundant availability and high cellulose content (32-47%). The process of making bioplastics was carried out with variations in the composition of potato starch and rice straw stalk cellulose (100%: 0%; 87.5%: 12.5%; 75%: 25%; and 62.5%: 37.5%), with the addition of chitosan (2 g) and glycerol (2 ml) as additives. The characterizations conducted included water absorption test (ASTM D570-98), biodegradation test, tensile strength test (ASTM E8M), percent elongation (ASTM D882-12), and identification of functional groups using FTIR (Fourier Transform Infrared). The results showed that the addition of rice straw cellulose had a positive effect on the characteristics of bioplastics. The best water absorption test was obtained in sample C (75% Starch: 25% Cellulose) with a value of 13% which meets the ASTM D570-98 standard. The best biodegradation test was obtained in sample B (87.5% Starch: 12.5% ​​Cellulose) with a value of 62%. The maximum tensile strength value was recorded at 1.23 MPa in sample C, and the maximum percent elongation value was 99.2% in sample D. FTIR analysis confirmed the presence of main functional groups (O-H, C-H, N-H, C-O) which indicated an effective interaction between potato starch, rice straw cellulose, and chitosan. Overall, this composite bioplastic shows optimal potential and characteristics as an environmentally friendly material.

Abstract

This study discusses the use of natural iron sand in the manufacture of magnetite nanoparticles with oleic acid. The purpose of the study is to produce nano-sized magnetite as an alternative photocatalyst material. Magnetite nanoparticles were synthesized with variations of oleic acid (0.75 ml, 1.5 ml, 2.25 ml, 3 ml) and the addition of 7.5 ml of diethylamine. Synthesis was carried out using XRF to determine the elements contained in the iron sand, SEM to determine the surface morphology, and UV-Vis to determine the size of the bandgap. The results showed that increasing the oleic acid content significantly increased agglomeration due to the large number of particles that merged with each other, while increasing the bandgap value. The results showed that the addition of oleic acid had an effect on the iron sand. The highest XRF test of 88.234% was obtained in the iron sand sample before processing, the lowest SEM test was 0.9 μm, and the highest UV-Vis test was 2.644 eV indicating an increase in the bandgap energy value due to the role of oleic acid as a surfactant. The novelty of this research lies in the use of natural iron sand combined with a fixed proportion of oleic acid (up to 3 ml) and diethylamine (7.5 ml). A good bandgap for the photocatalyst is 2.638 eV which is influenced by the addition of oleic acid as a surfactant. These magnetite nanoparticles show optimal potential and characteristics as photocatalyst materials.
