Abstract

This study analyzes the technical, allocative, and economic efficiency of rice farming in Gantar District, Indramayu Regency, using Data Envelopment Analysis (DEA) with an input-oriented Variable Returns to Scale (VRS) model and Tobit regression to assess socioeconomic determinants of technical efficiency. Based on 99 rice farmers selected using the Slovin formula, results show an average technical efficiency of 0.974, indicating near-frontier performance, though labor input exhibits notable slack. Allocative efficiency averages 0.875, while economic efficiency reaches 0.829, implying a potential improvement of 17.1%. Tobit results indicate that education, experience, land status, group membership, and credit access do not significantly affect technical efficiency. The study underscores the need for better input optimization and cost management to improve farm efficiency and sustainability.

Abstract

This study examines the effectiveness of complaint handling for BNI Emerald priority customers at Bank BNI KCU Cirebon, where high service expectations contrast with ongoing issues such as slow resolution, inconsistent service quality, and limited follow-up communication. Using a descriptive qualitative approach, data were collected through interviews, observations, and documentation involving priority customers, relationship managers, and customer service officers. Analysis was guided by service effectiveness indicators (Gibson et al.) and complaint handling criteria (Johnston & Mehra). The findings show that while complaint handling follows established procedures, its effectiveness remains suboptimal, particularly in resolution timeliness, information transparency, and customer satisfaction. Staff competence and accessible complaint channels support service delivery, whereas layered escalation, limited personnel, and inconsistent communication hinder optimal performance.

Abstract

Cigarette packaging contains cellulose acetate, which is difficult to decompose and pollutes the environment. This study aims to utilize this waste as an alternative growing medium in hydroponic systems. The experimental method was applied to water spinach (Ipomoea aquatica) plants by comparing its performance with Rockwool. The implementation stages included physical cleaning, sterilization with 70% alcohol, and boiling to remove harmful chemical residues. Based on observations over 26 days, the Independent Sample T-test results showed a significant value of 0.86 (p > 0.05). This indicates that there was no significant difference in plant height and number of leaves. The implication is that cigarette butt waste has been proven to be effective as a growing medium equivalent to Rockwool.

Abstract

Internet addiction (IA) is an addiction that is increasingly experienced by the community, especially teenagers and young adults. Papua, as a disadvantaged region, faces various challenges, ranging from infrastructure backwardness, high illiteracy rates, and low quality of education. On the other hand, internet access is improving.The purpose of this study was to examine internet addiction specifically among first-year students at the Cenderawasih Faculty of Medicine, who are under 20 years of age. Of course, the research respondents complied with the provisions of the Internet Addiction Diagnostic Questionnaire (KDAI). This study found that 26.3% of students experienced internet addiction. Students need internet guidance or a supportive learning system to minimize the risk of internet addiction (IA).

Abstract

This research stems from a growing concern regarding the vulnerability of Cirebon City, particularly the Harjamukti District, toward disasters that often bypass grassroots preparedness. My primary focus was to question the actual readiness of houses of worship as vital communal hubs. Using a quantitative descriptive approach via the Slovin formula, I gathered data from 47 multi-religious sites. The findings reveal a compelling dilemma: while risk knowledge and human resource capacity appear adequate, emergency planning and early warning systems remain alarmingly neglected. This suggests a significant gap between theoretical understanding and technical execution on the ground. Consequently, strengthening the institutional framework of these religious centers must become a policy priority for the BPBD. Future studies should further scrutinize the effectiveness of regular disaster simulations within these sacred spaces.

Abstract

The present study examines the mediating influence of teacher–student relationship (TSR) and perceived teacher autonomy support (PTAS) in the association between classroom emotional climate (CEC) and learners’ motivation (LM) among the Bangladeshi university English as a Foreign Language (EFL) learners. Applying a quantitative method, survey data were gathered from 250 EFL-centric learners and analysed through PLS-SEM and SPSS. The results highlight that CEC significantly influences TSR and PTAS, both of which, in turn, positively impact LM. Moreover, TSR and PTAS have partial mediation in the link between CEC and LM. The study extends motivational theory in the context of EFL by underscoring relational, emotional, and autonomy-assisted classroom procedures and provides practical implications for promoting a motivating learning atmosphere in higher education.

Abstract

Ecological issues are not just ordinary problems but global issues that affect grassroots communities that are powerless in terms of knowledge, social, economic, cultural, and religious aspects. The objective is to analyze the presence of religious minority communities in responding to the ecological crisis in Southeast Aceh through the contextualization of ecological theology from the encyclical Laudato Si’, using a qualitative phenomenological approach through interviews and focus group discussions with 26 participants in 2025. The results of the study show the successful implementation of an integral ecology model that transforms reforestation from a technical action into a practice of faith, supported by the synergistic integration of three dimensions: spiritual as a driver of ecological conversion, social through participatory community structures, and technical with sustainable methods such as agroforestry. The main conclusion offers a transformative solution: that addressing the ecological crisis must begin with a transformation of the heart driven by spirituality, strengthened by community, and manifested in systematic concrete actions, while also becoming a blueprint for contextual and value-based environmental conservation. This research contributes to developing a model that promotes social and cultural awareness, as well as ecological conversion, which can be used to create educational curricula from elementary to university levels. Additionally, it serves as a policy recommendation for both the government and the Catholic Church regarding Christian anthropological theology education.

Abstract

This study examines how agricultural extension contributes to institutional development in a women-led urban farming group, using KWT Sahabat Sampah in Bekasi City as a case study. The group integrates waste management and hydroponic vegetable production, illustrating an emerging model of community-based urban sustainability. A descriptive quantitative approach was employed, with all 35 members participating through census sampling. Data were collected via structured questionnaires, field observation, and interviews with the assigned extension agent. Results indicate that extension support was consistently rated high across six dimensions, particularly facilitation. Institutional development indicators were likewise strong, though economic sustainability remains constrained. Spearman’s rank correlation (ρ = 0.678, p < 0.01) shows a substantial association between extension intensity and institutional development. These findings suggest that participatory, context-sensitive extension approaches are well-suited to urban settings and can strengthen women’s organizations as local sustainability actors.

Abstract

This paper argues that Karl Marx’s theory of historical materialism remains partially valid and analytically fruitful when reformulated in dialogue with contemporary social theory. After clarifying social development, it reconstructs the core claims of forces and relations of production, class struggle, and modes of production. It examines failed empirical predictions, doubts about socialism or communism, objections to economic reductionism, and concerns about Eurocentrism. By placing historical materialism into conversation with structural functionalism, conflict theory, interpretive approaches, rational-choice and biosocial accounts, it proposes a non-teleological, multi-causal reconstruction retaining its explanatory core for digital capitalism and global inequality.
