Abstract

This study aims to analyze the effectiveness of pineapple peel waste-based ecoenzymes as liquid organic fertilizer on the height growth of mung beans (Vigna radiata L.). Ecoenzymes are the result of organic waste fermentation with carbon sources from sugar and water, produced through the activity of decomposing microbes. The compounds contained therein, such as enzymes, organic acids, and beneficial microorganisms, play an important role in increasing soil biological activity, improving soil structure, and accelerating the absorption of nutrients by plant roots. The research was conducted in a laboratory experiment using a three-main-treatment design, namely: control without fertilizer, application of pineapple ecoenzyme liquid organic fertilizer, and application of EM4 liquid organic fertilizer as a commercial comparison. Observations were made every two days during a 14-day period, focusing on the variable of plant height increase. The results showed that the pineapple ecoenzyme treatment significantly increased vegetative plant growth, with an average growth of 10.40 cm, higher than the control (6.20 cm) and close to the EM4 results (11.10 cm). These findings confirm that pineapple ecoenzyme has the potential to be an environmentally friendly liquid organic fertilizer alternative, which not only supports plant growth but also contributes to sustainable household organic waste management

Abstract

This research comprehensively evaluates the economic, technological, and environmental feasibility of green hydrogen adoption in Bogor City's transportation sector. Utilizing Techno-Economic Assessments (TEA), Life Cycle Assessment (LCA), and Scenario Modeling, the study compares centralized versus decentralized production pathways. TEA findings indicate that decentralized production is not financially viable, while centralized production with CCS technology shows positive financial potential, underscoring the role of economies of scale. LCA results confirm that green hydrogen offers significant emission reduction potential, up to 90% compared to fossil fuel alternatives, and produces zero emissions at the point of use, though high CCS costs remain a constraint. Scenario Modeling determined that Scenario 3 (high carbon tax, government subsidies, and reduced renewable energy prices) is the most effective pathway for accelerated adoption. Cost-Benefit Analysis (CBA) suggests that long-term non-economic benefits, such as improved public health and reduced air pollution, significantly outweigh high initial infrastructure costs. This study provides a novel, integrated assessment for a high-density urban context, advising policymakers to implement a higher carbon tax and subsidies to expedite the transition.

Abstract

Analytical thinking is essential for physics education students, yet comprehensive assessment remains challenging. This study investigates the distribution and characteristics of analytical thinking abilities using Rasch model analysis, examining gender differences and performance patterns. A cross-sectional study was conducted with 35 physics education students (20 females, 15 males) using a 20-item multiple-choice assessment covering four domains: identifying problems, recognizing relational patterns, identifying reasoning errors, and summarizing main ideas. Data were analyzed using Winsteps software to examine person abilities and group comparisons. Results revealed highly variable analytical thinking abilities (range = 8.84 logits, M = -0.15, SD = 1.79). Males outperformed females by 0.46 logits (males: M = 0.15; females: M = -0.31), though not statistically significant (p > 0.05). Three performance levels emerged: high achievers (25.7%, n = 9), average achievers (48.6%, n = 17), and low achievers (25.7%, n = 9). The findings reveal significant heterogeneity in analytical thinking abilities with observable gender-based differences. Results suggest the need for differentiated instructional approaches tailored to varying ability levels and targeted interventions to support struggling students. This study demonstrates the utility of Rasch analysis in identifying areas for instructional improvement and optimizing analytical thinking development in physics education contexts

Abstract

The purpose of this study is to analyze how teachers’ pedagogical competence contributes to the implementation of the Indonesian Madrasah Competency Assessment (AKMI) program and its influence on students’ literacy performance. This research employs a descriptive–exploratory qualitative design using multiple case study sites in three districts: Kuningan, Majalengka, and Ciamis across the MI, MTs, and MA levels. Qualitative data were collected through in-depth interviews, observations, and document analysis, while quantitative data from teacher pedagogical competence questionnaires and student AKMI report cards were used as supporting materials to strengthen the interpretation of the qualitative findings. The results show that AKMI training (BIMTEK) has been implemented adequately, enabling teachers to apply literacy-based lesson planning and contextual learning strategies. Teachers reported gains in understanding differentiated learning and the use of AKMI reports, although several challenges remain—particularly limited conceptual mastery, insufficient dissemination, tight implementation schedules, and constraints in online training. The analysis also indicates a tendency that higher pedagogical competence is aligned with better student literacy outcomes, although the relationship is not yet strongly consistent across levels. In conclusion, pedagogical competence plays an essential role in supporting the effectiveness of AKMI implementation, yet continuous mentoring and strengthened conceptual training are required to optimize program outcomes.

Abstract

The use of chemicals in industry has benefits and negative impacts that follow. Solvent chemicals in the printing area of PT X are used to wash screen printing. One of the impacts of chemical use is the occurrence of impaired lung function in workers. The purpose of this study was to determine the factors associated with impaired lung function in workers in the printing area of PT X. This study is an observational study with a Cross Sectional approach. The population in this study was 84 workers in the printing area of PT X, with a total sample of 70 workers who have had a working period of more than 1 year. Data analysis was carried out by univariate and bivariate analysis using the Chi Square test. The results of this study indicate that there is a relationship between the habit of using PPE and impaired lung function in workers in the printing area of PT X (p value = 0.028), and shows no relationship between length of service (p value = 0.949), nutritional status (p value = 0.688), smoking intensity (p value = 0.967), exercise habits (p value = 0.957) with impaired lung function in workers in the printing area of PT X. Therefore, supervision through inspections and internal audits is needed in the implementation of occupational safety and health, especially in terms of the use of masks to prevent chemicals from entering the body.

Abstract

Baeckea frutescens is a medicinal species widely used in traditional practices and known for its rich phytochemical diversity, yet its pharmacological profile remains fragmented across multiple studies. This systematic review aims to integrate current evidence on the phytochemical constituents and pharmacological activities of B. frutescens, focusing on anti-inflammatory, antimicrobial, antioxidant, anticancer, wound-healing, and insecticidal effects. A literature evaluation was conducted using previously compiled research comprising 16 studies from China, Indonesia, Malaysia, and Southeast Asia, covering chemical isolation, essential oil analysis, in vitro assays, in vivo experiments, and computational approaches. The results indicate that B. frutescens contains meroterpenoids, phloroglucinol derivatives, flavonoids, phenolics, and terpenes that collectively contribute to significant modulation of NF-κB, MAPK, TLR4–MyD88, and COX-related pathways. Essential oils and polar extracts exhibit broad antimicrobial and antioxidant activities, while cytotoxic and wound-healing assays demonstrate promising therapeutic potential. Insecticidal studies further highlight ecological relevance through antifeedant and repellent properties. Overall, the review confirms B. frutescens as a pharmacologically versatile species with strong prospects for drug discovery and functional applications. However, further mechanistic and in vivo investigations are needed to strengthen its translational value.

Abstract

This study aims to analyze the factors influencing the difficulty of implementing the Last Planner System (LPS) among contractors in Malang City. A quantitative approach was employed through questionnaires distributed to contractors involved in construction projects, supported by interviews to validate field findings. The data were analyzed using descriptive techniques and factor weighting to identify the variables that most significantly affect the challenges of LPS implementation. The results indicate that four major factors contribute to the level of difficulty in applying LPS: limited understanding and competence of human resources, lack of management support and commitment, weak coordination and communication among project teams, and resistance to organizational cultural change. The most influential factors are managerial and organizational behavioral aspects, particularly related to management commitment and readiness for collaborative work culture. These findings confirm that successful LPS implementation relies not only on technical tools but also on organizational readiness to adopt a culture of collaboration, transparency, and accountability. The study recommends strengthening human resource capacity, enhancing managerial support, optimizing routine coordination, and transforming organizational culture to improve the effectiveness of LPS implementation in Malang City.
