Abstract

Kegiatan PKM ini dilakukan di Dusun Sumbergebang RT 002/RW 013 Desa Langkap Kecamatan Bangsalsari, dimana penduduk di daerah tersebut kebanyakan bekerja sebagai petani, selain mayoritas berprofesi sebagai petani, warga dusun sumber gebang juga memiliki bermacam usaha, seperti usaha produksi camilan, peternakan ayam, produksi mebeul, dan usaha warung sembako. Namun, tidak mungkin jika seluruh masyarakat di daerah tersebut melakukan usaha yang sama. Oleh karena itu, Tim PKM berinisiatif untuk melakukan pendampingan atau pelatihan untuk memulai melakukan usaha dan membetuk kelompok usaha. Usaha yang akan dikembangkan adalah usaha berskala Industri Rumah Tangga (IRT) atau home industry. Usulan produk yang akan dikembangkan adalah korean strawberry milk minuman sehat kaya manfaat dan mengandung banyak vitamin. Langkah penyelesaian kegiatan pengabdian ini adalah diawali dengan Tahap Persiapan, Pembentukan kelompok pelaku usaha skala Industri Ibu Rumah Tangga (IRT), Pelatihan dan pendampingan pada masyarakat untuk melakukan usaha kreatif dan inovatif, Pelatihan pembuatan minuman korean strawberry milk sebagai inovasi produksi, dan Pelatihan pemasaran produk berbasis digital marketing melalui media sosial. Hasil dari kegiatan pengabdian ini adalah terbentuknya kelompok usaha rumahan, pengetahuan tentang usaha kreatif yang menghasilkan produk inovatif, pengetahuan branding dan pengemasan, serta pengetahuan digital marketing.

Abstract

The purpose of this research is to determine the navigation of an unmanned aircraft automatically using theory of the metric dimension of stars in a forest fire area. The research will also be expanded by determining the star metric dimensions on other unique graphs and graphs resulting from amalgamation operations. The methods used in this research are pattern recognition and axiomatic deductive methods. The pattern detection method is to look for patterns to construct differentiated sets on the metric dimension (dim) so that the coordinate values are minimum and different. Meanwhile, axiomatic deductive is a research method that uses deductive proof principles that apply in mathematical logic by using existing axioms or theorems to solve a problem. Then the method is used to determine the stars' metric dimensions.

Abstract

Sentiment analysis is used to understand the direction of public opinion, but problems arise due to the unbalanced distribution of sentiment data, where one class dominates. This imbalance causes classification models such as Support Vector Machine (SVM) to be biased towards the majority class, which results in decreased accuracy and generalizability of the model. This study aims to assess the effectiveness of two data balancing techniques, namely, SVM-SMOTE, and ADASYN, in improving SVM performance. The research data was taken from social media platform X (Twitter), and testing was conducted using the K-Fold Cross Validation method (K=2, 5, and 10) using evaluation metrics such as accuracy, precision, recall, and F1-score. The results show that without data balancing, the SVM model can only achieve an average accuracy of 76.34% and F1-score of 62.38%, which reflects the weakness in recognizing minority classes. The application of the two balancing methods successfully improved the model performance. ADASYN increased the F1-score to 67.94%, while SVM-SMOTE showed the most optimal results with 82.4% accuracy and 74.02% F1-score. These findings indicate that SVM-SMOTE is the most effective technique in handling data imbalance and improving sentiment classification accuracy equally.

Abstract

Abstrak: Desa Cakru memiliki potensi besar dalam perikanan air tawar, namun belum dimanfaatkan secara maksimal. Belum adanya produk olahan khas yang bernilai jual tinggi menjadi kendala utama, ditambah keterbatasan keterampilan teknis masyarakat dalam budidaya ikan lele dan pengolahan produk. Selain itu, pemanfaatan teknologi sederhana belum optimal. Program pengabdian ini bertujuan meningkatkan kapasitas masyarakat dalam budidaya ikan lele dan inovasi produk frozen food, sebagai upaya pemberdayaan ekonomi melalui branding oleh-oleh khas daerah. Kegiatan ini menitikberatkan pada peningkatan hardskill dalam teknik budidaya ikan lele dan pengolahan frozen food, serta softskill dalam kewirausahaan, manajemen usaha kecil, dan strategi branding agar produk lokal mampu bersaing di pasar. Metode pelaksanaan mencakup sosialisasi, pelatihan teknis, penerapan teknologi tepat guna, pendampingan intensif, serta evaluasi menggunakan observasi, angket, dan pretest serta posttest berbasis 15 soal pilihan ganda. Kegiatan melibatkan terdiri dari 15 pembudidaya pemula dan 10 pelaku usaha mikro yang berpotensi mengembangkan produk olahan berbasis ikan lele. Hasil menunjukkan peningkatan hardskill sebesar 61% dan softskill 58%, serta peningkatan pendapatan keluarga sebesar 20–30% dari pemasaran produk frozen food.Abstract: Cakru Village has great potential in freshwater fisheries, but has not been utilized optimally. The absence of typical processed products with high selling value is the main obstacle, coupled with the limited technical skills of the community in catfish cultivation and product processing. In addition, the use of simple technology has not been optimal. This community service program aims to increase community capacity in catfish cultivation and frozen food product innovation, as an effort to empower the economy through branding regional souvenirs. This activity focuses on improving hard skills in catfish cultivation techniques and frozen food processing, as well as soft skills in entrepreneurship, small business management, and branding strategies so that local products can compete in the market. The implementation method includes socialization, technical training, application of appropriate technology, intensive assistance, and evaluation using observation, questionnaires, and pre-tests and post-tests based on 15 multiple-choice questions. The activity involved 15 novice cultivators and 10 micro-entrepreneurs who have the potential to develop processed products based on catfish. The results showed an increase in hard skills of 61% and soft skills of 58%, as well as an increase in family income of 20-30% from marketing frozen food products.
