ental sustainability, and competitiveness remain obstacles in the industry's value chain. Innovation in various aspects of the value chain, such as productivity improvement through agricultural technology, processing efficiency, and product diversification based on palm oil, is a key factor in enhancing the industry's competitiveness. This study aims to analyze the role of innovation in the palm oil industry value chain in Merauke Regency by identifying the types of innovations applied and the factors that support or hinder their adoption. The research employs a qualitative approach, using data collection techniques such as in-depth interviews, observations, and document studies. The findings indicate that upstream sector innovations, such as the use of superior seedlings and digital plantation management, have improved productivity and efficiency. Meanwhile, downstream innovations in palm oil processing and value-added product diversification still face challenges, particularly in infrastructure and regulatory aspects. The study's implications suggest that optimizing innovation in the palm oil value chain requires more adaptive policies, increased investment in research and development, and capacity building for human resources. Thus, innovation can serve as a driving force in creating a more competitive, sustainable palm oil industry that contributes to local economic development in Merauke Regency.

sion 21 program was used to analyze the effectiveness of communication between corn planting teachers. The results of the analysis show that (1) the overall level of farmer participation in agricultural extension activities is included in the less active category. Compared to the participation stage, farmers are more active in implementation than planning. Corn farmers in Marobea Village are more active than corn farmers in Lakalamba Village. (2) Agricultural extension communication between corn farmers in Marobea and Lakalamba Villages is most effective in increasing knowledge (cognitive) and subsequently influencing attitudes (affective), but less effective in encouraging action tendencies (behavioral). Extension communication between corn farmers in Marobea Village is more effective compared to corn farmer groups in Lakalamba Village. The more active farmers are, the more motivated they are to apply extension materials. and (3) Factors that determine the effectiveness of extension communication include extension factors, extension methods, and facilities and infrastructure. Extension factors related to the effectiveness of extension communication are the attitude, communication and knowledge aspects of the instructor. Aspects of method suitability and effectiveness are also related to the effectiveness of extension communication which is supported by the availability of extension infrastructure.

ol to help teachers convey the Word of God in class. Such as the use of props that can help teachers convey stories to children in class. The use of props that involve IT or audio visual media-based technology such as videos, televisions, slides is expected to attract children’s attention so that they can understand the essence of the story. The teaching of audio-visual media is inspired by the teaching method that the Lord Jesus applied when teaching the crowds and His disciples, “Look at the birds of the sky who neither plant nor reap nor gather into barns” (Matthew 6:34). In teaching, the Lord Jesus often used natural media as a way for Him to convey His Word. This research discusses the role of audio visual media used by teachers in delivering various topics. This research uses a qualitative approach with descriptive methods. Based on this research, it is concluded that the role of audio-visual media is so great in helping Sunday school teachers in teaching to be easily accepted and understood by children and recorded more easily in children’s memory.

et valuation, property, plant and equipment (PPE), goodwill, and research and development expenditure on bankruptcy risk, proxied by the Altman Z-score, among publicly listed companies in ASEAN countries. The study employs a quantitative approach using secondary data obtained from 1,354 non-financial firms listed in Indonesia, Malaysia, Thailand, Singapore, and the Philippines over the 2015–2023 period, yielding a total of 7,726 firm-year observations. Data were analyzed using a fixed-effects panel regression model. The findings reveal that asset growth and goodwill exert a positive and significant effect on the Altman Z-score, whereas research and development expenditure has a negative and significant effect. Revenue growth demonstrates a marginally positive influence, while market valuation and PPE do not exhibit a significant effect on bankruptcy risk. These results suggest that corporate financial stability is determined not only by financial factors but also by the quality of strategic resources and firms’ adaptive capabilities. The novelty of this study lies in the integration of the Resource-Based View and Dynamic Capabilities Theory perspectives into a bankruptcy prediction framework for publicly listed companies across ASEAN countries.

ademic, social, and mobility activities of the academic community, which heavily depends on pedestrian facilities. Field observations reveal several key issues with the pedestrian facilities in this area, including the sidewalk width not meeting the minimum standard, lack of accessibility features for people with disabilities, absence of vegetation or shade, and insufficient signage and road markings to guide users. These conditions result in discomfort and insecurity for pedestrians, as well as failing to support the principles of inclusivity in infrastructure planning. The research employs a descriptive qualitative and quantitative approach with a case study method. Data were collected through field observations, questionnaires, interviews, and literature reviews. Based on the analysis, the majority of respondents expressed the need for improvements to the sidewalk quality, addition of shade trees, enhanced accessibility for people with disabilities, and the installation of supporting facilities such as street lighting. The study then recommends several improvement measures, such as widening the sidewalks to at least 1.5 meters, providing ramps and Guiding blocks, planting vegetation along the pedestrian routes, and installing road signs and markings. These recommendations aim to improve pedestrian comfort and safety. It is hoped that the results of this study can serve as a reference for Muhammadiyah University of Bengkulu in creating a campus area that is more friendly, safe, comfortable, and inclusive for all users, while also supporting sustainable mobility.

adition is not only a series of ceremonies or astrological calculations, but also a cultural heritage that includes local wisdom values and spiritual beliefs that have been passed down from generation to generation. In the current era of globalization, the wetonan tradition is faced with various challenges that threaten its survival. Changes in people’s attitudes and mindsets, urbanization, and doubts about traditional values are some of the main challenges. Shifting values and priorities in society, changes in value and belief systems, and doubts about the role of tradition in the era of globalization are some of the main challenges. However, preserving the wetonan tradition is crucial to maintaining a rich and diverse cultural identity and strengthening the solidarity of Javanese indigenous communities. To maintain and face the challenges of the wetonan tradition remaining relevant and valued by the community, concrete steps are needed. In facing this challenge, it is important to continue to educate the public about the cultural and spiritual values contained in the wetonan tradition, as well as to replant these values to strengthen the sustainability of the wetonan tradition amid the ongoing flow of modernization and globalization. Thus, the wetonan tradition can continue to live and develop as an integral part of the cultural identity of Javanese society. The preservation of this tradition not only ensures the continuity of a rich cultural heritage, but also strengthens solidarity and togetherness in Javanese indigenous communities. Therefore, measures to maintain and preserve the wetonan tradition need to be continuously strengthened to ensure that this cultural heritage remains alive and relevant for future generations.
