Rubber (Hevea brasiliensis) is an important plantation commodity that contributes to improving rural livelihoods. However, the productivity of smallholder rubber plantations remains relatively low due to various technical constraints, socio-economic conditions, and limited farmers’ knowledge and technology. This study aims to analyze the influence of technical aspects of cultivation and socio-economic aspects on farmers’ knowledge and technology in rubber cultivation in Desa Antutan, Kecamatan Tanjung Palas, Kabupaten Bulungan. This research employed a mixed methods approach with a descriptive design. Quantitative data were collected through questionnaires distributed to 30 rubber farmers selected using purposive sampling, while qualitative data were obtained through in-depth interviews and documentation. Quantitative data were analyzed using multiple linear regression with SPSS software, while qualitative data were analyzed through data reduction, data display, and conclusion drawing The results indicate that technical aspects of cultivation and socio-economic aspects simultaneously influence farmers’ knowledge and technology in rubber cultivation. Partially, technical cultivation aspects have a more dominant effect than socio-economic aspects. Qualitative findings reveal that the main problems faced by farmers include improper tapping techniques, aging rubber trees, rubber price fluctuations, and limited access to agricultural training and extension services.

Independent plantations are a favorite in the Jambi Regional economy, as they are a source of economic growth, employment, exports, and foreign exchange for the region. Despite their relatively low productivity, oil palm plantations in Jambi Province have a major competitive advantage compared to other commodities. This study aims to describe, analyze competitiveness, analyze policy impacts, and conduct sensitivity tests on independent oil palm plantations. The research location was in Merlung District, selecting three sample villages: Tanjung Paku Village, Merlung Village, and Lubuk Terap Village purposively, with a total sample of 43 farmers. The data analysis method used the (PAM) method. The results of the analysis show that independent farmers still have relatively low productivity. The DRCR value is 0.379 (<1) and the PCR value is 0.368 (<1) which indicates savings in the use of domestic resources by 37.9% and 36.8%. These results indicate a comparative and competitive advantage. The divergence impact shows a negative impact, meaning that government policies are not distorted properly, as indicated by an NPCI value of 1.18 (> 1) and an NPCO value of 0.87 (< 1). Sensitivity tests show that independent oil palm plantations still have competitiveness (< 1), despite experiencing policy distortions such as input price increases (11% and 25%) and a decrease in FFB prices (45%).  

This study examines the export barriers encountered by emerging small and medium-sized enterprises (SMEs) in Indonesia, with a focus on export documentation challenges, tariff constraints, and the adaptive marketing strategies employed to sustain international market engagement. Employing a qualitative case study approach, this research investigates PT Albarka International Group, a nascent export-import company established in 2021 and headquartered in Malang, East Java, which specializes in the export of natural commodities including Bakhur-related materials (opercula shells, damar resin, agarwood), spices, and other Indonesian products to Middle East markets including Yemen, Saudi Arabia, UAE, Libya, Sudan, and Djibouti. Data were collected through in-depth interviews with key company personnel and supplemented by document analysis. Findings reveal three primary export barriers: (1) high shipping tariffs relative to regional competitors, frequently triggering order cancellations by importers; (2) complex and time-intensive export documentation requirements, particularly for regulated natural resource products subject to CITES compliance, fish quarantine certification (Health Certificate), and customs declaration (PEB); and (3) internal organizational constraints stemming from overlapping job roles. In response, PT Albarka has adopted adaptive strategies including Full Container Load (FCL) consolidation to reduce per-unit shipping costs, advance payment systems (TT in advance) to mitigate importer default risk, and collaborative consultation with customs and quarantine authorities. The study contributes to the SME internationalization literature by demonstrating how resource-constrained emerging exporters navigate institutional and logistical complexities in developing economy contexts, offering practical insights for SME practitioners and export policy stakeholders.

Cucumber (Cucumis sativus L.) is a high-value horticultural commodity, but its production has declined due to drought stress affecting plant physiology and female flower formation. To address this issue, the use of mulch and planting spacing can modify the microclimate and reduce inter-plant competition. This study aimed to evaluate the effects of rice straw mulch and planting spacing on the growth, yield, and environmental conditions of cucumber. A factorial randomized block design was employed with two factors: mulch (no mulch and rice straw mulch) and planting spacing (40 × 60 cm, 50 × 50 cm, and 60 × 40 cm), replicated four times. Observed variables included vegetative growth, number of male and female flower, yield, soil temperature, and soil moisture. The study was conducted from June to August 2025 at the Agrotechnopark, Brawijaya University. The results showed a significant interaction between rice straw mulch and 50 × 50 cm planting spacing on fruit diameter, fruit length, fruit weight per fruit, fruit weight per plant, and plant productivity. This combination also created a more stable soil environment. It is concluded that the application of rice straw mulch with a 50 × 50 cm planting spacing is the optimal combination for enhancing cucumber growth and yield through improved microclimate conditions, however, these research are limited to a single growing season and a single experimental location.

Sugarcane cultivation often faces productivity losses due to poor sprouting and non-uniform initial growth. In bud-based nursery systems, seedling quality is heavily constrained by limited media volume and low buffering capacity. This study aimed to evaluate the synergistic effects of NPK fertilizer dosages and Gibberellic Acid (GA) concentrations on the growth and physiological vigor of sugarcane seedlings. The experiment was conducted using a Completely Randomized Design featuring nine treatment combinations with four replications. Parameters measured included plant height, stem diameter, the number of tillers, the number of leaves, and the chlorophyll index. The results demonstrated that the application of the NPK 150 kg ha⁻¹ + GA 50 ppm treatment significantly enhanced plant height, stem diameter, number of shoots, and the number of leaves compared to the control treatment. Statistical analysis revealed a significant interaction between nutrient availability and hormonal stimulation in overcoming the constraints of limited rooting environments. These findings suggest that precise integration of chemical fertilization and exogenous growth regulators is essential for producing high-quality planting material, potentially reducing losses in the subsequent planting cycle. In the future, it is necessary to confirm the use of a combination of NPK fertilizer with gibberellin during the vegetative period of plants so that the information obtained is comprehensive.

Business activities are essential for helping the economy of society function properly. When starting a business, people usually want to make money, but they are also supposed to follow good values, like being honest in their dealings. In real life, some businesses still do unfair things, like giving false information about products, changing prices unfairly, lowering the quality of goods, and using incorrect measurements when selling items. This research focuses on explaining what honesty means and how it should be used in business according to the principles of Islamic economics. The study uses a qualitative method called literature review, which involves looking at books, journal articles, and other sources that talk about Islamic business ethics. The results show that honesty is a key value in Islamic business because it helps build trust with customers, ensures fair deals, and creates positive relationships between sellers and buyers. The value of honesty in the business world can be demonstrated through transparancy of information about products, honesty in pricing, accuracy in measurement, and not hiding defects in the goods being sold. From an Islamic economics perpective, business activities should not only focus on material income, but also on the value of blessings, ethical responsibility, and mutual prosperity. Thus, the application of honesty in an important foundation for building fair, transparent bisuness practices that are in line with Islamic economic prinsiples.

The increase in the number of elderly residents demands the provision of residential facilities that not only meet physical needs, but also support the psychological and social well-being of their users. This study aims to formulate the concept of behavioral architecture-based nursing home design by focusing on the relationship between elderly activity patterns, privacy levels, and spatial relationships of space in the local context of Indonesia. This study uses a qualitative-descriptive approach in the framework of architectural design, with data collection through observation of elderly activities, site analysis, and documentation studies. Activity data was analyzed to identify space needs and usage patterns, then synthesized with site characteristics to formulate the concepts of zoning, circulation, and behavior-based spatial relationships. The results of the study show that the activities of the elderly form a layered behavioral structure, including residential and health activities as primary needs as well as social, productive, and educational activities as support for psychosocial welfare. Hierarchically arranged space zoning based on privacy levels has been proven to improve the readability of the space, sense of security, and comfort of the elderly. The integration of green open spaces as part of the activity system also strengthens support for light physical activity and social interaction. This study confirms that the application of behavioral architecture allows the translation of data on elderly behavior and site conditions into a contextual, humanist, and quality-of-life-oriented design concept. These findings provide practical implications for designers and policymakers in the development of sustainable elderly housing.

The problem of illegal temporary shelters (TPS) is one of the serious environmental issues in Jambi City. Danau Sipin District is the district with the highest number of illegal TPS in Jambi City, namely 13 points. This study aims to determine the performance of the Environmental Management, Supervision and Enforcement Division (P3HL) the Jambi City Environmental Service the productivity aspect of the problem of illegal TPS in Danau Sipin District using the theory of public organization performance by Agus Dwiyanto (2006) with primary focus on productivity indicators. This can be seen from the utilization of various inputs such as human resources consisting of 3 field officers, operational facilities in the form of 1 patrol car, Standard Operating Procedures (SOP) for supervision, as well as clear and easy public reporting mechanisms to produce various outputs in the form of field supervision activities, enforcement of regulations, education and socialization to the public, and follow-up public reports. Although these various activities have been carried out, the limited number of field officers and operational facilities has resulted in the intensity of supervision in the field not being able to be carried out optimally. The conclusion of this study shows that the performance the Environmental Arrangement, Supervision and Law Enforcement Division of the Jambi City Environmental Service in terms of productivity has been running well, but still requires improvement, especially in the addition of human resources and operational facilities so that supervision and enforcement of regulations against illegal TPS can be carried out more optimally.

This study aims to explore employees’ work experiences related to work-life balance and compensation in shaping employee performance at CV. Sepanjang Masa (Masa Kreatif), a social media agency located in Makassar. A qualitative approach with a descriptive-analytical field design was employed. Data were collected through in-depth interviews, passive participant observation, and documentation involving 11 informants from both management and creative teams. Data analysis followed processes of data reduction, data display, and conclusion drawing, with trustworthiness ensured through triangulation techniques. The findings reveal that employees’ work-life balance experiences are dynamic and heterogeneous. Work flexibility provides opportunities for personal time management; however, rapid response demands and intensive content production blur the boundaries between work and personal life. A supportive, communicative, and collaborative work environment acts as a protective factor that mitigates work pressure and fosters creativity. Compensation is perceived not only as financial remuneration but also as a symbol of recognition, professional development opportunities, and organizational appreciation, although gaps remain between employee expectations and organizational capacity. Integratively, work-life balance, work environment, and compensation constitute interconnected work experiences influencing employee engagement and performance within the digital creative industry.

Gluten-free flour-based cookie products face a major challenge in producing physicochemical and sensory characteristics equivalent to wheat-based products due to the absence of gluten as a structural component. One common approach to address this issue is the addition of hydrocolloids, such as glucomannan and xanthan gum. This study aims to systematically examine the effect of the ratio of glucomannan and xanthan gum on the texture characteristics, spreadability, and sensory properties of gluten-free flour-based chocolate cookies using the Systematic Literature Review (SLR) method. The literature search process was carried out on several scientific databases using keywords related to gluten-free cookies, glucomannan, xanthan gum, texture, spreadability, and sensory properties. Selected articles were selected based on inclusion and exclusion criteria, then analyzed and synthesized narratively with reference to the PRISMA guidelines. The results of the study indicate that xanthan gum tends to increase the hardness and structural stability of cookies, but can decrease spreadability and crispiness at high concentrations. Conversely, glucomannan plays a role in enhancing softness and mouthfeel through its high water-binding capacity, although it can potentially limit spreadability if used excessively. The combination of glucomannan and xanthan gum exhibits a synergistic effect in balancing textural characteristics and enhancing sensory acceptability. In conclusion, optimizing the ratio of glucomannan to xanthan gum is a key factor in developing gluten-free chocolate cookies with optimal physicochemical and sensory characteristics.

The transition toward sustainable energy systems requires the transformation of renewable energy marketing strategies, particularly for waste-based energy. This study aims to analyze the effects of green marketing, stakeholder collaboration, and technological innovation on the marketing effectiveness of waste-based energy, with customer satisfaction as an intervening variable.

Structural Equation Modeling (SEM) was used to analyze the data. The results indicate that green marketing, stakeholder collaboration, and technological innovation significantly influence customer satisfaction and the effectiveness of marketing. Furthermore, customer satisfaction significantly mediates the relationship between independent variables and marketing effectiveness. These findings emphasize the importance of integrating sustainable marketing strategies, multi-stakeholder synergy, and innovative technologies to enhance the competitiveness of waste-based energy products in the market. This study contributes to the theoretical development of renewable energy marketing models and provides practical implications for policymaking and green energy marketing strategies in Indonesia.

This study examines the effectiveness of zakat distribution during the leadership of Umar bin Abdul Aziz and its relevance to poverty alleviation models in Indonesia. Structural poverty remains a persistent challenge in Indonesia’s economic development, requiring systematic and sustainable solutions. Within Islamic economic thought, zakat functions not only as a religious obligation but also as a fiscal instrument capable of promoting social welfare and economic independence. This research employs a qualitative approach through historical and literature study methods, analyzing classical Islamic governance practices alongside contemporary zakat management in Indonesia. The findings reveal that the success of zakat distribution under Umar bin Abdul Aziz was supported by centralized governance, strong institutional reform of Baitul Mal, strict supervision, and integrity-based leadership, resulting in effective wealth redistribution and significant poverty reduction. The study further finds that productive zakat distribution, institutional integration, regulatory reinforcement, and digital transparency are crucial elements for enhancing the performance of zakat institutions in Indonesia. The implications suggest that strengthening governance, accountability, and productive empowerment programs can transform zakat into a strategic socio-economic policy instrument capable of addressing structural poverty in a sustainable manner.

Indonesian Sign Language (Bahasa Isyarat Indonesia, BISINDO) is often misunderstood as merely a gestural or simplified form of communication, undermining its linguistic sophistication and contributing to barriers to deaf inclusion in Indonesia. Approximately 2.6 million deaf individuals in the country rely on BISINDO as their primary language. This study explores the linguistic complexity of BISINDO, documenting its phonological, morphological, syntactic, and semantic systems. Using a mixed-methods approach, we analyzed 150 hours of BISINDO conversations from 80 deaf signers, conducted experimental studies on phonological distinctions and syntactic complexity, and performed ethnographic fieldwork in deaf communities and schools. Comparative analysis with American Sign Language (ASL) was also conducted. Our findings demonstrate that BISINDO is a fully developed natural language, with 45 handshapes, 18 locations, 23 movements, and 4 orientations in its phonological system. It shows productive morphological processes, flexible word order, and rich semantics, including idioms and metaphors. However, there are significant barriers to inclusion: 68% of deaf students lack qualified BISINDO teachers, and 84% of public services lack sign language interpreters. Furthermore, 72% of hearing Indonesians still do not recognize BISINDO as a legitimate language. Deaf community organizations, however, report BISINDO as central to their identity. The study highlights the need for policy reforms, including BISINDO recognition as an official language, qualified interpreters, bilingual deaf education, and public awareness campaigns to combat misconceptions.    

Occupational health is an important aspect in maintaining worker productivity and safety, particularly in sectors with a high risk of chemical exposure such as gas stations (SPBU). Gas station workers are potentially exposed to hazardous chemical compounds such as benzene, toluene, and xylene which may affect the hematopoietic system and lead to decreased hemoglobin (Hb) levels. The use of Personal Protective Equipment (PPE) is one of the preventive measures to minimize exposure to these hazardous substances. This study aimed to determine the relationship between the use of Personal Protective Equipment (PPE) and hemoglobin levels among female workers exposed to fuel at gas stations in Kendari City. This study employed a quantitative research design with a descriptive analytic approach using a cross-sectional method. The population in this study consisted of all female fuel filling operators working at gas stations in Kendari City, totaling 30 workers, who were all included as research samples. Data on PPE usage were obtained through observation and questionnaires, while hemoglobin levels were measured using a Hematology Analyzer with venous blood samples collected in EDTA tubes. Data analysis was conducted using univariate and bivariate statistical tests to determine the relationship between PPE usage and hemoglobin levels. The results showed that out of 30 respondents, 21 (70%) had normal hemoglobin levels and 9 (30%) had abnormal hemoglobin levels. A total of 20 respondents (66.7%) used PPE according to the required standards, while 10 respondents (33.3%) did not meet the PPE requirements. Statistical analysis showed a p-value of 0.104 (p > 0.05), indicating that there was no significant relationship between PPE usage and hemoglobin levels among female gas station workers in Kendari City. The study concludes that the use of PPE does not have a significant relationship with hemoglobin levels among female gas station workers in Kendari City. However, the consistent use of PPE is still recommended as a preventive measure to protect workers from exposure to hazardous chemicals in the workplace.

This study analyzes the concept of al-Kasb in the view of Muhammad ibn al-Hasan al-Shaybani and assesses the relationship between this concept and contemporary work ethics. With the changes in the modern economic system, which emphasize efficiency, objective rationality, and the achievement of optimal results, various ethical conflicts in the professional and business world have become more apparent. The methodology applied in this study is a literature review with a descriptive-analytic approach, through the analysis of classical and contemporary texts to explore the theological, ethical, and social aspects contained in the concept of al-Kasb, and then conceptually compare it with the characteristics of modern work ethics. The findings of this study show that al-Kasb is not only understood as an economic activity aimed at accumulating wealth, but also as a normative guide that integrates the goals of worship, ethical responsibility, and social obligations in the production process. Work activities are viewed as an individual responsibility that supports the practice of worship and as a collective responsibility to maintain social-economic welfare and harmony. Therefore, al-Kasb provides an integrative ethical foundation that has the potential to enrich and strengthen current work ethics by emphasizing values of integrity, justice, and social responsibility in the economic aspects of life.
