Abstract

The implementation of this community service aims to improve the ability of students with disabilities to prepare digital-based business plans and marketing. This service method uses training, which consists of the introduction activity stage of market research and identification of business opportunities, the action stage for implementing the business plan and the evaluation stage. The evaluation instrument for this activity uses a questionnaire and is analyzed descriptively. The results of this community service show: 1) the entrepreneurial abilities of students with disabilities have increased; 2) the knowledge of students with disabilities regarding digital business opportunities increases; 3) the knowledge of disabled students regarding business planning using the Business Model Canvas (BMC) increases; and 4) knowledge of students with disabilities regarding digital promotion and marketing methods increases so that they are able to market products through social media and market places.

Abstract

Bintang laut merupakan salah satu kelompok dari kelas Asteroidea dan termasuk kelompok yang paling beragam dalam filum Echinodermata. Keberadaan bintang laut tidak hanya mencerminkan keanekaragaman hayati laut, tetapi Bintang laut juga berkontribusi terhadap stabilitas ekosistem laut dan dapat digunakan sebagai indikator kualitas lingkungan karena sensitif terhadap perubahan kondisi perairan. Setiap spesies bintang laut memiliki perbedaan morfologi, terutama pada bentuk tubuh dan susunan lengan, yang dapat digunakan sebagai dasar identifikasi spesies. Penelitian ini bertujuan mengklasifikasikan spesies bintang laut berdasarkan bentuk tubuh dengan menggunakan pendekatan dimensi fraktal metode Box Counting. Sebanyak 120 citra bintang laut digunakan dalam penelitian ini. Pengolahan citra meliputi remove background, cropping, konversi grayscale, segmentasi, dan deteksi tepi Canny. Selanjutnya, metode Box Counting digunakan untuk menghitung dimensi fraktal yang kemudian diklasifikasikan menggunakan algoritma KMedoids menjadi delapan klaster, yaitu Gomophia Egyptiaca, Leptasterias Hexactis, Tosia Australis, Luidia Maculata, Choriaster Granulatus, Astropecten Articulatus, Protoreaster Nodosus, dan Linckia Laevigata. Hasil pengelompokan delapan jenis bintang laut memperoleh akurasi 90,83%.
