Padi hitam merupakan sumber karbohidrat yang bermanfaat untuk kesehatan. Pengujian daya hasil merupakan tahapan penting dalam menentukan keberhasilan pemuliaan padi beras hitam. Tujuan penelitian ini ialah untuk memperoleh informasi keragaan agronomi dan menyeleksi galur-galur dihaploid padi beras hitam yang memiliki penampilan agronomi baik dan berdaya hasil tinggi untuk pengujian multi lokasi. Penelitian ini dilakukan dari bulan November 2019 sampai Juli 2020 di Bogor, Jawa Barat dan Malang, Jawa Timur. Sebanyak 23 galur dihaploid padi hitam yang memiliki sifat agronomi baik dengan produktivitas tinggi dan 3 varietas pembanding yaitu Aek Sibundong, Jeliteng, dan Inpari 24 digunakan sebagai materi genetik. Studi ini menggunakan rancangan rancangan kelompok lengkap teracak dengan 3 ulangan pada setiap percobaan. Hasil penelitian menunjukkan bahwa interaksi genotipe dan lingkungan berpengaruh nyata terhadap semua karakter pengamatan kecuali pada karakter lama pengisian gabah berdasarkan analisis keragaman. Sebanyak 14 galur yang terseleksi berdasarkan indeks terboboti memiliki karakteristik jumlah anakan produktif per rumpun dari 15.8 hingga 25.9, umur panen genjah dari 115.2 to 121.9 hari setelah semai, dan produktivitas >5.4 ton ha-1. Keragaan agronomi dan daya hasil galur-galur dihaploid padi yang terseleksi pada penelitian ini memerlukan pengujian lebih lanjut melalui uji multi lokasi untuk memperoleh calon varietas unggul baru padi beras hitam. Kata kunci: agronomi baik, indeks seleksi, kriteria seleksi, kultur antera padi
As one of the multinational biscuit manufacturers in Bekasi, the X company is supported by Business Planning and Control System (BPCS) for the traceability in their supply chain. Although it has covered upstream and downstream supply chains, the company’s traceability is still considered ineffective. It is seen from the results of the company’s evaluation through the mock recall procedure. The research aims to identify the requirement of a mobile traceability system for mock recall procedures, design components of mobile traceability system prototype based on an android system, and validate the mobile traceability system and performances. The business process analysis in this research is using Business Process Model and Notation (BPMN) to trace the system. The results show that traceability is still less effective because activities are done manually, which takes much time. Therefore, the system is developed with cosine similarity calculation and verification of the model and validation of the black box. The verification and validation of the system against its needs show that the mobile traceability system can improve the effectiveness of company traceability and can be applied in the internal supply chain.
