Abstract

Model transpor sedimen dan perubahan topografi dasar pantai akibat pengaruh medan gelombang dan arus perairan pantai telah dibangun untuk mensimulasikan evolusi (erosi-deposisi) perairan pantai Mattoanging, Bantaeng, Sulawesi Selatan. Model medan arus yang dibangkitkan oleh gelombang disimulasikan dengan menggunakan model hidrodinamika 2D-horizontal. Selanjutnya persamaan kekekalan massa sedimen digunakan untuk prediksi perubahan topografi dasar pantai berdasarkan model prediksi Watanabe dan Maruyama. Persamaan pengatur tersebut diselesaikan dengan metoda numerik beda hingga eksplisit. Input model perubahan topografi dasar pantai diperoleh dari model gelombang dan arus yang dibangkitkan oleh gelombang laut. Hasil simulasi model arus yang dibangkitkan oleh gelombang pada musim Barat memberikan magnitudo kecepatan berkisar (0.0 - 1.81) m/det dengan arah Timur menyusuri pantai dan pada musim Timur hasil model berkisar (0.0 - 0.82) m/det dengan arah Barat. Penerapan model transpor sedimen dan perubahan topografi dasar pantai dilakukan dua skenario. Skenario pertama dilakukan simulasi menggunakan data batimetri pantai Mattoanging tanpa jetty. Skenario ini menghasilkan perubahan topografi dasar pantai di sepanjang pantai. Skenario kedua dilakukan simulasi dengan jetty di daerah model. Skenario ini menghasilkan perubahan topografi dasar pantai di sekitar jetty karena arus melemah oleh adanya jetty. Model yang telah dibangun cukup mampu memperlihatkan fenomena fisis transpor sedimen dan perubahan morfologi perairan pantai yang disebabkan oleh pengaruh gelombang dan arus perairan pantai.

Abstract

This study aims to describe cooperation strategies in increasing public trust in Madrasah. This research method is a descriptive study, with a qualitative research approach. This research was conducted at an institution located in the Probolinggo area, namely MTs Al-Hasyimi. Informant sources were obtained from the head of the madrasa, public relations and MTs Al-Hashimi teachers, while the data collection methods used were interviews, observations and documentation. The findings of this study outline that basically the community is the main consumer who uses madrasah services. However, there are some madrassas that cannot show the qualities they possess to the public audience. This is where the role of partnership design strategies is used in an effort to collaborate with the layers of society so that strong trust grows from the community to the institution. The results showed that MTs Al-Hasyimi uses partnership design management to increase public trust in the institution, the management of partnership design is implemented by; planning, implementing cooperation strategies, controlling and evaluation. The focus of research is on how the activities intensified by Madrasah MTs Al-Hasyimi in forming relationships between the madrasah and the surrounding community in order to increase public trust

Abstract

This study aims to analyze the economic impact of the Kali Kembar tourist destination on the community of Gading Wetan Village, Probolinggo Regency, and to formulate sustainable development strategies. Kali Kembar, as a local ecotourism potential, has begun to attract regional visitors, yet its management remains suboptimal. The research employed a descriptive qualitative approach, with data collected through in-depth interviews, field observations, and document analysis. The findings reveal that the tourism site has brought positive economic impacts, including increased household income, the emergence of new business opportunities, and the circulation of the local economy through the informal sector. However, institutional management, infrastructure development, and promotional efforts remain key challenges. Proposed development strategies include strengthening the institutional capacity of tourism managers, enhancing facility quality and accessibility, developing attractions based on local wisdom, and fostering synergy between the village government and local entrepreneurs. This study recommends a community-based tourism development model as the primary approach to promote economic, social, and environmental sustainability in the area.
