Abstract

The transition toward a green economy necessitates a workforce equipped with green skills as a core competency to support industrial sustainability and competitiveness. However, the integration of green skills into the vocational training system in Indonesia continues to face various structural challenges and has yet to be managed in a systematic manner. This study aims to analyze the concept of green skills through the lens of the most recent literature, identify the challenges of their integration within vocational training institutions, and examine early practices of green skills implementation through a case study at the LPP Quantum Sampit Vocational Training Institute (Lembaga Pelatihan Profesi Quantum Sampit). The research employed an integrative literature review combined with an explanatory case study approach, utilizing policy document analysis, international reports, and graduate tracer data from LPP Quantum Sampit for the period 2022–2025. The findings reveal six principal challenges in the integration of green skills: limitations in the existing policy framework; a curriculum that is not yet oriented toward green principles; insufficient instructor competence; inadequate training facilities and equipment; increasingly complex industry demands; and the absence of established green skills certification standards. These findings serve as the basis for the formulation of conceptual recommendations in the form of a five-pillar green skills integration framework, proposed as a strategic effort to strengthen the vocational training system in supporting Indonesia's transition to a green economy.

Abstract

Antimicrobial resistance (AMR) constitutes a serious global health issue, with its impact being especially pronounced in developing countries like Indonesia. Developing new antibacterial and antioxidant agents through structural modification offers a promising strategy to address AMR. Ferulic acid, a natural phenolic compound with known biological activity, has limited bioavailability. To enhance its potency, structural modification into hexyl ester and Mannich base derivatives was performed. Ferulic acid (1) was synthesized via solvent-free Knoevenagel condensation, converted to hexyl ferulate (2) through esterification with hexyl bromide, and further modified with dimethylamine (3a), diethylamine (3b), morpholine (3c), and 2,6-dimethylmorpholine (3d). The antioxidant assays (DPPH and FRAP) showed that 3a–d had IC₅₀ values of 1.89–22.67 µM and EC₅₀ values of 0.34–4.08 µM. Compounds 3b (EC₅₀ 0.34±0.00 µM) and 3d (IC₅₀ 1.89±0.00 µM) exhibited strongest antioxidant activity, exceeding the activity of ascorbic acid. Antibacterial testing showed 3d produced the largest inhibition zones, up to 26.90 mm at 3 mg/mL against S. aureus. MBC testing confirmed that 3b was the most active (0.75–3.00 mg/mL). The enhanced activities correlated with increased lipophilicity (logP 3.32–4.25). Overall, Mannich base substitution of hexyl ferulate significantly improved antioxidant and antibacterial properties, suggesting its potential as a lead scaffold for developing agents against resistant pathogens.

Abstract

This study aims to analyze the effect of investment decisions on firm value, with Corporate Social Responsibility (CSR) and profitability serving as moderating variables. The research sample consists of energy sector companies listed on the Indonesia Stock Exchange (IDX) during the 2022–2024 period, selected through purposive sampling based on predetermined criteria. The data used are secondary data derived from annual financial statements and sustainability reports obtained from the official IDX website. Data analysis is conducted using panel data regression with EViews software, and the best estimation model employed is the Fixed Effect Model (FEM). The results indicate that investment decisions proxied by the Price-to-Earnings Ratio (PER) do not have a significant effect on firm value proxied by Tobin's Q, suggesting that investment decisions have not become a primary indicator in assessing firm value in the energy sector. Furthermore, CSR measured using the Global Reporting Initiative (GRI) disclosure index does not significantly strengthen the relationship between investment decisions and firm value, indicating that CSR disclosure is not yet perceived as a strong signal by investors. In contrast, profitability proxied by Return on Equity (ROE) is found to significantly strengthen the effect of investment decisions on firm value, highlighting the role of profitability in reinforcing investment decision signals amid high earnings volatility in the energy sector.

Abstract

Technological Pedagogical and Content Knowledge (TPACK)-based learning is a strategic agenda for improving the quality of education in primary schools. Teachers, as the main implementers of instruction, require systematic management support to effectively integrate technology, pedagogy, and content. This study aims to describe the management of TPACK-based learning through the POAC (Planning, Organizing, Actuating, Controlling) framework in enhancing student achievement at SDN Pekojan 03 and SDN Pekojan 05 Jakarta Barat. The research employed a qualitative approach with a case study design through observations, interviews, and document analysis involving principals, teachers, and students. The findings reveal that planning for TPACK-based learning has been incorporated into instructional documents, yet its implementation remains inconsistent; organizing is still simple with limited ICT management teams; actuating involves the use of digital applications and interactive media, though not evenly across all classrooms; and controlling tends to focus more on administrative compliance rather than in-depth reflection on TPACK effectiveness. Limited facilities, teachers’ digital literacy, and unstable internet connectivity emerge as the main challenges, although both principals and teachers demonstrate strong commitment to sustaining digital learning innovation. The study concludes that applying POAC in TPACK-based learning has the potential to enhance teacher creativity, student engagement, and learning achievement, provided that it is supported by needs-based planning, structured team organization, collaborative implementation, and reflective as well as continuous supervision. It is expected that this study contributes to the development of adaptive, innovative, and sustainable TPACK-based learning policies and practices in primary schools.

Abstract

Virgin Coconut Oil (VCO) and ginger (Zingiber officinale Rosc.) have antibacterial and anti-inflammatory activities, making them potential natural alternative therapies for the treatment of gingivitis. Although their biological effectiveness has been proven, the physical stability of this combination spray preparation has not yet been evaluated. The spray formulation was chosen because it is practical, provides even distribution, and minimises contamination. To determine the effect of physical stability testing of a 10% VCO-ginger spray combination as a candidate material for the treatment of gingivitis. Laboratory experimental research was conducted by creating five formulations (F1-F5). Stable formulations were subjected to a cycling test and physical stability evaluation, including organoleptic testing, homogeneity, pH, viscosity, spreadability, and adhesion. Data analysis was performed descriptively. Formulation F5 showed the best physical characteristics with a milky white colour, a distinctive coconut-ginger smell, a homogeneous liquid texture, a pH of 6.019-6.823, a spreadability of 5.0-6.1 cm, an adhesion of 19.27-29.72 seconds, and a viscosity of 346.7-692.8 cP. Formulation F5 has physical performance potential as a candidate for gingivitis therapy, but its emulsion stability is limited under extreme temperature conditions. Optimisation of surfactant concentration is required to prevent viscosity reduction and phase separation during long-term storage.

Abstract

The rapid growth of the K-pop industry in Indonesia is reflected in its strong cultural influence among Indonesian youth, making the country one of the largest K-pop fan markets globally. This growth is driven not only by high music consumption but also by significant fan spending on related activities, particularly concert attendance. K-pop concerts often require substantial expenses, including tickets, accommodation, merchandise, and supporting services such as make-up artists and phone rentals. The frequency of these transactions has encouraged fans to establish microbusinesses by utilizing their skills, assets, and prior experience. However, the K-pop concert microbusiness ecosystem largely operates informally through fragmented social media platforms without clear regulations or standardized systems, creating challenges such as trust issues, scam risks, unclear coordination, and inconsistent service delivery. This study aims to examine how innovative solutions can be designed to address these challenges and generate value for all stakeholders within the ecosystem. The study employs Empathy Mapping to analyze behaviors and motivations of involved parties, alongside Customer Journey Mapping to examine step-by-step processes and identify pain points at each interaction stage. The findings are translated into innovation concepts using Doblin’s Ten Types of Innovation and the Value Proposition Canvas to ensure alignment with user needs. Finally, Lean Canvas and Minimum Viable Product (MVP) frameworks are applied to translate concepts into implementable solutions. The results indicate that innovation focused on trust-building and coordination standardization plays a critical role in reducing uncertainty, improving service consistency, and supporting long-term business sustainability within the microbusiness ecosystem.

Abstract

This study investigates the transition from intention to actual behavior in socially responsible investment (SRI) among young retail investors in Indonesia. Drawing on an extended Theory of Planned Behavior (TPB), the research integrates core TPB constructs— attitude, subjective norms, and perceived behavioral control—with financial literacy and environmental concerns as additional predictors, while incorporating risk propensity as a moderating variable. Using survey data collected from 342 Indonesian retail investors dominated by Generation Z and Millennials, the study employs Structural Equation Modeling (SEM) with SmartPLS 4 to examine both direct and indirect relationships among variables. The results reveal that intention toward SRI plays a central mediating role in shaping actual SRI behavior. Attitude and perceived behavioral control significantly influence intention but do not directly translate into behavior, indicating the presence of an attitude–behavior gap. In contrast, subjective norms exert a significant direct effect on both intention and behavior, highlighting the strong role of social influence in emerging market contexts. Financial literacy and environmental concerns are found to significantly affect both intention and behavior, reinforcing the importance of cognitive capacity and pro- environmental orientation in sustainable investment decisions. Moreover, intention significantly mediates the effects of all antecedent variables on SRI behavior. These findings contribute to the SRI literature by providing empirical evidence from an emerging market and underscore the necessity of strengthening intention formation through social norms, sustainable financial literacy, and supportive investment infrastructure to promote responsible investment behavior among young investors.

Abstract

Tinnitus, defined as the perception of sound without external auditory stimuli, is often associated with psychological stress, particularly among students facing high academic demands. This study aims to describe psychological distress as a contributing factor to tinnitus among medical students and to provide an overview from an Islamic perspective. A descriptive quantitative design with a cross-sectional approach was employed. The sample consisted of 84 students from the Medical Education Program, Faculty of Medicine, YARSI University, Class of 2023, selected using purposive sampling. Data were collected using the General Health Questionnaire-12 (GHQ-12) to measure psychological distress and the Tinnitus Handicap Inventory (THI) to assess tinnitus severity. Data analysis was conducted using univariate descriptive statistics with SPSS. The results show that the majority of respondents experienced positive psychological distress (89.3%), indicating relatively stable mental conditions, while 10.7% experienced negative distress. Regarding tinnitus, most respondents were in the none or very mild category (86.9%), with minimal impact on daily activities. These findings suggest that although psychological distress is present, tinnitus incidence remains generally low among students. In conclusion, psychological stress may contribute to tinnitus occurrence, but its severity is mostly mild, emphasizing the importance of stress management and maintaining psychological well-being

Abstract

This research aims to explore the phenomenon of the influencer profession as a strategic solution for Generation Z in dealing with the high unemployment rate through the use of the digital creative economy. The main focus of this study is to analyze how foodie nano-influencers from Generation Z construct their identities as an instrument to strengthen personal branding on social media. Using a qualitative approach, this study applied Stuart Hall's identity construction theory which views identity as a dynamic process of "becoming", as well as Peter Montoya's personal branding theory to dissect self-image strategies. The results show that the identity construction of these nano-influencers is flexible (dynamic identity), where they adaptively adjust communication styles and content based on audience preferences and directives from brand partners. The personal branding strategy applied includes eight main laws (The Eight Laws of Personal Branding), namely Specialization (The Law of Specialization), Leadership (The Law of Leadership), Personality (The Law of Personality), Difference (The Law of Distinctiveness), Consistency (The Law of Visibility), Unity (The Law of Unity), Steadfastness (The Law of Persistence), and Good Name (The Law of Goodwill). These findings confirm that digital identity is not just a self-representation, but a planned strategy to build credibility and unlock economic opportunities amid fierce competition in the digital industry.
