Abstract

Abstrak Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan efisiensi produksi Kelompok Wanita Tani (KWT) Ar Rama di Desa Telukjambe, Kecamatan Telukjambe Timur, Kabupaten Karawang melalui pendekatan Material Flow Cost Accounting (MFCA). MFCA digunakan sebagai kerangka analitis untuk mengidentifikasi pemborosan material, menghitung biaya produk positif dan negatif, serta mendasari tiga intervensi produksi utama: penerapan Good Manufacturing Practices (GMP), adopsi teknologi mesin, dan diversifikasi produk berbasis sumber daya lokal. Metode pelaksanaan mencakup sosialisasi, pelatihan, dan pendampingan langsung selama 14 minggu. Hasil kegiatan menunjukkan peningkatan kebersihan produksi sebesar 75%; pengurangan limbah bonggol singkong sebesar 90%; dan diversifikasi produk baru berupa tepung tapioka, peyek, dan cheese stick dari pati singkong yang sebelumnya menjadi produk negatif MFCA (peningkatan 100%). Secara keseluruhan, efisiensi produksi KWT Ar Rama meningkat sebesar 88%. Kata kunci: material flow cost accounting; kelompok wanita tani; efisiensi produksi; GMP; diversifikasi produk. Abstract This community service activity aimed to improve the production efficiency of the Ar Rama Women Farmer Group (KWT) in Telukjambe Village, Karawang Regency through a Material Flow Cost Accounting (MFCA) approach. MFCA was employed as an analytical framework to identify material waste, calculate positive and negative product costs, and guide three main production interventions: Good Manufacturing Practices (GMP) implementation, production machinery adoption, and product diversification based on local resources. Implementation comprised socialization, training, and direct mentoring over 14 weeks. Results showed a 75% improvement in production hygiene; a 90% reduction in cassava stub waste; and new product diversification—tapioca flour, peyek crackers, and cheese sticks—from cassava starch previously classified as a negative product in MFCA (100% improvement). Overall, KWT Ar Rama’s production efficiency improved by 88%. Keywords: material flow cost accounting; women farmer group; production efficiency; gmp; product diversification.

Abstract

On-time graduation (OTG) is a primary key performance indicator (KPI) for higher education institutions. Delays in graduation adversely affect institutional academic efficiency and increase student costs. This study aims to implement the Support Vector Machine (SVM) algorithm, a machine learning technique, to develop a predictive model for students' on-time graduation. This study employed a quantitative approach using a historical dataset of 20 students as a case study. Five predictor variables were utilized: Semester 4 GPA, total completed credits, attendance percentage, working status, and organizational activity. The dataset was partitioned into 80% for training and 20% for testing. Model performance was evaluated using a Confusion Matrix, along with Accuracy, Precision, Recall, and F1-Score metrics. The evaluation on the test set demonstrated that the SVM model achieved an overall Accuracy of 75%. Specifically for the 'On-Time' class, the model yielded a Precision of 66.7%, a Recall of 100%, and an F1-Score of 80%. These findings suggest that SVM is a viable method and holds potential as an early detection tool to identify students at risk of delayed graduation, thereby enabling timely intervention.

Abstract

Terdapat banyak pelabelan graf yang telah dikembangkan, salah satunya adalah pelabelan graceful. Pelabelan graceful dari graf dengan E busur dan V simpul adalah pelabelan yang memenuhi fungsi injektif sedemikian sehingga label busur yang dihasilkan diperoleh dengan cara pada setiap busur berbeda secara berpasangan. Pada penelitian ini, kami membahas tentang pelabelan graceful graf hasil korona bunga mawar yaitu untuk dan untuk Graf bunga mawar dikenal sebagai graf tengah dari graf lingkaran. Misalkan adalah himpunan simpul dari graf lingkaran , . Graf bunga mawar dapat dibentuk dari graf lingkaran dengan simpul dan simpul terisolasi dan kemudian menghubungkan setiap dua titik dengan untuk dimana . memiliki simpul dengan derajat 2 dan simpul dengan derajat 4. Graf produk hasil korona bunga mawar yang dapat ditulis sebagai dibentuk oleh operasi korona pada graf bunga mawar dengan menambahkan r simpul daun pada setiap simpul.
