One important aspect of waste management is the grouping and sorting of waste based on its type. However, waste sorting carried out by the public is often inaccurate or inconsistent. This can be caused by a lack of knowledge about waste types, confusion in identifying the correct type, or difficulty in memorizing complex sorting guidelines. Therefore, a system is needed that can detect waste types quickly and accurately without involving a large amount of human labor. One technological solution that can be used is machine learning. The method used in this study is the Random Forest algorithm. The data used consists of waste grouped based on characteristics such as texture and shape. This data is processed through feature extraction and preprocessing before being applied to the Random Forest model. The model's accuracy is tested using cross-validation techniques to assess classification performance. The experimental results show that the Random Forest algorithm can achieve a high level of accuracy in detecting waste types. The accuracy obtained reaches 94%, with consistent results in each cross-validation fold. This model proves to be effective in classifying different types of waste using the available features. The implementation of the Random Forest algorithm in waste type detection demonstrates great potential in improving technology-based waste management systems. With high accuracy, this model can be applied to various waste classification systems in society, helping to improve the efficiency of recycling processes and waste reduction.

Kegiatan ini dilatar belakangi oleh masalah yang dihadapi mahasiswa dalam bekomunikasi. Masih dimukan keluhan dari dosen terkait cara komunikasi mahasiswa yang kurang efektif, baik dalam proses pembelajaran maupun dalam berkomunikasi sosial dalam pergaulan. Untuk mengatasi masalah tersebut, sehingga diberikan solusi berupa pelatihan public speaking untuk meningkatkan kemampuan komunikasi mahasiswa. Kegiatan ini dilakukan dengan metode seminar dan simulasi. Kegiatan ini diawali dengan perencanaan dan analisis masalah, perencanaan pemberian solusi, pelaksanaan kegiatan, dan evaluasi, laporan,dan publikasi. Kegiatan ini dilaksanan di Universitas Muhammadiyah Makassar dengan melibatkan mahasiswa Prodi Manajemen dan PGSD. Teknik pengumpulan data melalui wawancara, angket, dan teknik analisis data deskriptif. Hasil kegiatan menyimpulkan bahwa pelatihan public speaking dapat meningkatkan kemampuan dan keterampilan mahasiswa dalam berkomunikasi efektif serta kemampuan berbicara di depan umum. Kegiatan tersebut juga terlaksana efektif dengan indikator bahwa pemahaman peserta terkait materi mencapai 83,33%; tingkat kepuasan peserta mencapai 91,67%; penyampaiaan materi yang jelas mencapai 91,67%; kesesaian materi dengan topik kegiatan mencapai 100%; dan kegiatan pelatihan dapat memberi solusi dari masalah public speaking mencapai 91,67%; dan kepuasan terhadap fasilitas mencapai 91,67%. Hasil ini memperkuat penelitian sebelumnya bahwa pelatihan public speaking dapat meningkatkan kemampuan komunikasi. Sehingga keterampilan public speaking perlu dimiliki oleh setiap mahasiswa sebagai calon tenaga kerja professional.

The era of globalization has prompted countries, including Indonesia, to reconsider their defense capabilities in the face of increasingly complex threats. Indonesia's primary focus lies in the development of the maritime sector, given its strategic geographic position between the Pacific and Indian Oceans. Maritime security is crucial for smooth trade, considering that Indonesia is the world's second-largest producer of fish. The significant potential of marine resources requires attention to maritime security. Concurrently, globalization has altered the patterns and forms of threats, especially in international trade routes such as the Malacca Strait.This research employs the method of literature study to depict Indonesia's maritime conditions, infrastructure development, and the impact of globalization on maritime trade. The government's focus on enhancing logistical efficiency and infrastructure development aims to support industrial and trade growth. However, challenges persist, particularly in optimizing the management of marine resources and improving coordination among relevant institutions. In this context, Indonesia is presented with an opportunity to become a strong maritime nation with global competitiveness, supported by an active community and a profound understanding of its maritime identity.
