Agribusiness Performance through Innovation: The Case of Arabica Bemba Coffee in Enrekang
Full text linkThis study examines how innovation capability and market orientation influence agribusiness performance through post-harvest process innovation in the case of Bemba Arabica in Enrekang. A quantitative-explanatory design using PLS-SEM was employed with 80 multi-source respondents (farmers/groups, operators/QC, managers/marketing, B2B buyers). A Likert-type 1–5 instrument was tested for reliability and validity; a structural model assessed direct, indirect, and total effects. Results indicate innovation capability and market orientation have a significant positive effect on process innovation; process innovation has a significant positive effect on agribusiness performance. The direct effect of innovation capability on performance is small but significant, while the direct effect of market orientation on performance is insignificant indicating a dominant mediating role of process innovation. Findings confirm that standardized SOPs for fermentation–drying, QC/cupping, and traceability are the primary pathways for converting “market voice” and innovation capability into economic value. Practical implications include prioritizing standardization across suppliers, strengthening measurement/experimentation capacity, and managing structured market feedback
Strategic Decision Making for Facility Optimisation in Indonesia’s Gunung Kemala Oil Field Using AHP
Full text linkThe focus of this research is the strategic optimisation of surface production facilities under capital and governance constraints, in Indonesia’s brownfield oil assets of Gunung Kemala (GNK), within a state-owned-enterprise (SOE) governance context. An integrated Multi Criteria Decision Making (MCDM) model is formulated, jointly involving Value-Focused Thinking (VFT) to organise policy objectives, Kepner–Tregoe (KT) Decision Analysis to filter “Must” criteria and “Want” criteria, and the Analytical Hierarchy Process (AHP) for ranking four strategic alternatives: i.e., constructing a new facility, upgrading current facilities, utlisation of idle assets and renting third-party infrastructures. The raw data was obtained through conversation, focused group discussion and expert pairwise comparison with seven experts from domain knowledge. The comparison results reveal that utilization of idle assets appears as the biggest preferred alternative (global priority weight = 0.547) and compared to greenfield & brownfield expansions. This dominance derives from the capital efficiency, faster deployment time, reduced regulatory exposure and better alignment with asset-governance constraints. This research presents an integrated VFT–KT–AHP decision framework that is designed specifically for the brownfield bottle necks in emerging-market upstream settings. It expands the traditional AHP application from technical based ranking to incorporate issues in governance feasibility and asset utilization strategies as an internal capital allocation decision logic, providing a solution model that is applicable with other SOE oriented energy systems
Aging Alone in Malaysia: Social Challenges and Legal Protections
Full text linkAccording to The Japan Times, nearly 28,000 elderly individuals in Japan will die alone in the first half of 2024. This alarming trend is not unique to Japan; many countries, including Malaysia, are facing the challenges of an aging population. As Malaysia approaches becoming an aging nation, issues affecting the elderly, particularly those living alone, demand urgent attention. While not all elderly people face the same circumstances, some enjoy stable finances or live with their family, while others live in isolation due to various factors, such as remaining unmarried, widowhood, or estranged familial ties. Some are simply separated by their distance from their children, who live elsewhere. The growing number of elderly individuals living alone has raised concerns about social neglect and the risk of dying unnoticed. The aim of this article is to examine the issue and challenges faced by the elderly living alone and to assess the legal framework that protect their rights in Malaysia. Using a doctrinal legal research approach, the authors examined the legal frameworks in Malaysia, Singapore and the United Kingdom on the rights and protections of elderly living alone. The findings reveal significant legal gaps in protection and social support available for elderly living alone in Malaysia. This article proposed the need to strengthen the existing legal framework, enhance social supports and foster community initiatives for elderly living alone, ensuring that no one is forgotten
The Impact of AI-Driven Predictive Marketing on Ethical Perceptions and Strategic Business Outcomes
Full text linkAI-driven predictive marketing promises superior targeting, personalization, and decision speed, yet its strategic payoffs depend on how customers and managers judge the ethics of its use. This study examines whether and how capability in AI-powered predictive marketing improves strategic business outcomes by shaping ethical perceptions in privacy and consent, transparency and explainability, and fairness and non-discrimination. Drawing on Resource-Advantage theory, we propose and test a model in firms from Makassar, Indonesia, spanning creative industries, financial services, food and beverage, and technology. Using Partial Least Squares Structural Equation Modeling with higher-order constructs, we assess direct, indirect, and conditional effects, including mediation by governance quality and moderation by perceived manipulation and perceived market concentration or data dominance. The estimates show that stronger AI-PM capability is associated with more favorable ethical perceptions, and these perceptions relate positively to brand trust and credibility, innovation readiness, competitive advantage, and performance. Governance practices, consent management, bias audits across pre-, in-, and post-processing, and explainability routines, act as the primary mechanism strengthening ethical perceptions and outcomes. Conversely, perceived manipulative design weakens capability–outcome links, and perceptions of market concentration reduce the ethical appraisal of personalization efforts. The findings position ethics-by-design as a market-based resource that renders data and algorithmic investments more legitimate and defensible over time. Managerially, firms should pair analytics stacks with governance stacks and invest in complementary IT and organizational readiness, while policymakers can enhance contestability and transparency to preserve choice and fairness in data-intensive markets
A new parasitic plant mite (Acari: Eriophyoidea) found on Trewia nudiflora L. (Euphorbiaceae) from India
Full text linkDuring the periodical surveys for plant mite in the area of the Gangetic Plain of India, a new species eriophyoid mite, Ditilomiopus trewiacolous sp. nov. of the family Ditilomiopidae is found on the lower surface of the leaves of Trewia nudiflora. Trewia nudiflora L. belonging to family Euphorbiaceae, is an important medicinal plant, grows in moist tropical and semi- evergreen forests as well as non-forest areas of India and its neighbouring countries, Bangladesh, China, and Malaysia. The plant is attacked by a tiny sap sucking parasitic mite belonging to the superfamily Eriophyoidea of subclass Acari of class Arachnida and produces severe damage to the host. This new parasitic mite species is collected and processed for microscopic study and finally described with sufficient illustrations following standard taxonomic procedure. The relationship to the host plant is also described here. A comparative study of this mite with other previously known species has been conducted. After proper taxonomic diagnosis, it is found that this parasitic mite appears as new to Science from India. New name with its etymology has been given to this mite species following the Rules of International Code of Zoological Nomenclature and also registered in Zoo-Bank account to create unique ID: LSID urn: lsid: zoobank.org:pub:3BC0363B-160B-46CE-B9DA- 20864762AD10. This study may be helpful to the plant protection departments and may provide the basis of further research including DNA barcoding and systematic evolution. This research finding may also be helpful to the students of Pharmacology and Medicinal Botany
Urbanization and Elderly Welfare: Dynamic Evidence from Indonesia
Full text linkThis study examines the relationship between urbanization and elderly welfare in Indonesia by integrating social, economic, and demographic dimensions, addressing the widely held assumption that urban development automatically enhances the well-being of older populations. Using balanced panel data from 34 Indonesian provinces for the period 2017–2022, obtained from the Indonesian Central Bureau of Statistics and the Ministry of Health, the study employs a dynamic panel model estimated through the Generalized Method of Moments (GMM) to capture short- and long-term effects while accounting for endogeneity. The results indicate that past elderly welfare conditions do not significantly influence current welfare levels. Urbanization is found to have no statistically significant effect on elderly welfare in either the short or long term. In the short term, health facility availability, poverty levels, and the proportion of elderly individuals negatively affect elderly welfare, whereas economic well-being exerts a positive influence. In the long term, economic well-being remains a key positive determinant, while the proportion of elderly individuals continues to have a negative effect. Overall, the findings demonstrate that elderly welfare in Indonesia is shaped primarily by socioeconomic factors rather than by the pace of urbanization. The study contributes original policy-relevant insights by challenging urbanization-centered development strategies and emphasizing the importance of targeted economic empowerment and inclusive social protection systems to improve elderly welfare
Beyond Refusal or Acceptance: Reformulating Administrative Silence in Indonesia from a Comparative French Model
Full text linkThe administrative silence is constructed as a legal fiction that originated as a negative (silence as refusal) and has since developed into a positive (silence as acceptance). In European administrative law, no system operates exclusively based on one legal fiction. Both negative and positive fictions are employed with defined limitations, as in France. Conversely, in Indonesia, these fictions are considered conflicting and override each other due to complex regulations and undefined limitations, leading to ambiguity. Therefore, this article aims to reformulate the concept of administrative silence in Indonesia through a comparative doctrinal legal research approach. The findings proved that both fictions have distinct conceptual origins and should be applied in their respective contexts. Although as fiction, their implementation, particularly in cases of positive fiction, should reflect the principle of administrative law that a decision is an expression of “will.” Consequently, Indonesia should reformulate its approach by applying both fictions simultaneously with defined limitations, based on the decision type: declarative or constitutive, rather than treating them as a dichotomy. Ultimately, this article contributes to comparative administrative law by examining administrative silence in Indonesia through the relationship between negative fiction, positive fiction, and decision typology based on comparison with the French model
The Effect of Augmented Reality in Online Beauty Retail on Brand Perception
Full text linkOne notable innovation is the use of Augmented Reality (AR), which allows consumers to virtually try on products, enhancing the online shopping experience. This study aims to examine the impact of AR usage and consumer engagement on the brand perception of Maybelline products on the Shopee e-commerce platform. Employing a quantitative explanatory research method, data were obtained through an online survey of 200 Shopee users in Indonesia who had interacted with AR features when exploring Maybelline products. The research investigates the relationships between AR, consumer engagement, and brand perception in the context of digital beauty marketing. The findings reveal that both AR usage and consumer engagement have a significant positive effect on brand perception. Moreover, consumer engagement is found to partially mediate the relationship between AR and brand perception. These results highlight the strategic importance of immersive technologies and active consumer involvement in building strong brand impressions. The study contributes to the growing body of knowledge on digital marketing in the beauty industry and offers practical insights for brands aiming to leverage AR tools to enhance customer experience and strengthen brand positioning in competitive e-commerce environments
Optimization of Bud Set Seedling Growth in Several Sugarcane Varieties (Saccharum officinarum L.) using Liquid Organic Fertilizer from Coffee Grounds
Full text linkThis study aims to study and determine the growth response of several varieties of sugarcane (Saccharum officinarum L.) on the application of coffee grounds liquid organic fertilizer (POC). This research was conducted in Gattareng Village, Salomekko District, Bone Regency, South Sulawesi from April to July 2022. The research was arranged in the form of a two-factor factorial experiment with a randomized block design (RBD) as an environmental design. The first factor is the variety which consists of three varieties namely PS 881, PS 865 and Kidang Kencana. The second factor was the POC concentration of coffee grounds which consisted of four levels, namely without POC, 15 mL/L, 30 mL/L and 45 mL/L. The results showed that the combination of the PS 865 variety with 15 mL/L POC coffee grounds gave results on the parameters of stem diameter (18.67 mm), fresh stem weight (66.50 g), stem dry weight (33.29 g) and root volume (35.33 mL). The PS 865 variety gave the best results on the parameters of plant height (34.61 cm), number of leaves (9.50), root wet weight (23.0 g), root dry weight (6.37 g) and root length (105 g). .92 cm) sugarcane seeds. POC coffee grounds 45 mL/L gave the best results on the parameters of plant height (33.67 cm), root wet weight (22.11 g), and root dry weight (5.86 g) of sugarcane seedlings
Converging Paths to Resilience: Analyzing Food and Energy Security Dynamics in SULAMPUA
Full text linkThis study examines the convergence of food and energy security in the Sulawesi, Maluku, and Papua (SULAMPUA) region as a key element of national resilience. Using a dynamic panel model with the Generalized Method of Moments (GMM) on data from 10 provinces (2018–2023), the analysis reveals that food security is strongly supported by agricultural technology assistance, which boosts productivity despite shrinking farmland. Equitable fertilizer subsidies are also critical, while natural disasters require targeted adaptation strategies. On the energy side, declining crude oil production weakens stability, but renewable energy development offers significant potential. However, infrastructure limitations and global oil price fluctuations remain significant challenges. Policy implications underscore the need to integrate food and energy strategies, combining agricultural technology, fertilizer subsidies, and accelerating renewable energy development. Green infrastructure, including clean-energy irrigation systems, can enhance resilience while reducing carbon emissions. Strengthening disaster risk management through early warning systems and local crop diversification is also vital. Additionally, energy price-stabilization policies, such as buffer stocks and fiscal incentives for renewables, are necessary to reduce dependence on global markets. Overall, the findings underscore the importance of a multisectoral, evidence-based approach to building sustainable resilience in the SULAMPUA region
