Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan dengan tujuan meningkatkan efektifitas dan praktikalitas kegiatan pemipilan jagung bagi masayarakat petani jagung di Kabupaten Pasaman Barat. Jagung menjadi sektor sandaran hidup bagi sebagian masyarakat khususnya di Pasaman Barat. Berdasarkan hasil observasi awal dan wawancara dengan Yunita sebagai ketua kelompok tani Boncah Bungo Tanjuang permasalahan yang paling dirasa urgen untuk segera diatasi adalah pada pasca panen jagung. Pada pasca panen harus dilakukan pemipilan terhadap biji jagung. Pada proses ini petani menghadapi masalah tingginya upah dan waktu yang dibutuhkan dalam proses pemipilan. Selain itu jika pemipilan tidak dilakukan dengan segera maka akan mempengaruhi kualitas dari biji jagung, hal ini berkaitan dengan kelembapan biji jagung sehingga mempengaruhi harga jual. Secara umum, kegiatan pengabdian ini berjalan dengan baik. Rancangan pelaksanaan kegiatan terlaksanakan dengan baik. Hasil yang didapatkan sangat memuaskan masyarakat. 75% masyarakat menilai kegiatan ini sangat bermanfaat dan berharap lebih banyak kegiatan pengabdian untuk dapat dilaksanakan di kenagarian Lingkuang Aua Timur. Masih terdapat banyak sector pertanian yang membutuhkan sentuhan teknologi dan masukan pengetahuan dari akademisi.

Abstract

Tujuan kegiatan ini adalah untuk meningkatkan nilai komuditi jagung. Harga biji jagung siap dirontok ini berkisar Rp.1.000,- – Rp. 1.500,- perkilonya. Nilai jual bisa ditingkatkan lagi aabila jagung dilakukan penumbukan sehingga pembeli jagung tumbuk untuk kosentrat pakan ayam tidak lagi membutukan proses penghalusan untuk campuran pakan ayam mereka. Harga jagung yang telah di tumbuk ini mencapai Rp. 3.500,- perkilonya. Perbedaan harga ini cukup signifikan. Sebahagian petani melakuan penumbukan biji jagung dengan cara manual. Sehingga waktu dan tenaga yang dibutuhkan menadi lama dan banyak. Melalui pengabdian ini tim pengabdian ingin melakukan inovasi untuk meningkatkan nilai jual komoditi jagung pakan ayam di kenagarian Lingkuang Aua Timur Kecamatan Pasaman Kabupaten Pasaman Barat. Mesin penggiling jagung yang direncanakan memiliki konsep seperti diskmild dengan rancangan blade segi lima. Motor penggerak yang direncanakan menggunakan motor bensing 5,5 HP. Estimasi mesin penggiling ini mampu melakukan penggilingan jagung 100 Kg/jam nya. Harapan tim pengabdian dengan adanya mesin penggiling jagung ini mampu meningkatkan nilai jual jagung dan berdampak pada peningkatan ekonomi para petani jagung di Kenagarian Lingkuang Aua Timur Kecamatan Pasaman Kabupaten Pasaman Barat. Mesin ini akan diserahkan pada kelompok tani Boncah Bungo Tanjuang yang berada di Kenagarian Lingkuang Aua Timur untuk dikelola dan dimanfaatkan masyarakat.

Abstract

The Merdeka Belajar-Kampus Merdeka (MBKM) policy is a strategic initiative of the Indonesian Ministry of Education, Culture, Research and Technology to revolutionize the higher education system through increasing student learning flexibility and freedom. The purpose of this study is to explore the academic landscape related to the MBKM policy through a bibliometric approach to identify research trends, publication patterns, academic collaboration, and dominant themes that appear in the scientific literature. The method used is bibliometric analysis by utilizing Biblioshiny, VOSviewer, and Microsoft Excel software on 210 documents obtained from the Dimensions database with the keywords “independent learning” and “higher education”. The results showed a significant increase in publications since 2020 with an annual growth rate of 92.56%, indicating high academic interest in MBKM. The top ten most cited articles raised issues of MBKM curriculum implementation, institutional adaptation challenges, and technology integration in learning. The analysis also revealed extensive collaboration between authors and institutions, as well as a diversity of keywords such as “flexible curriculum”, “project-based learning”, and “industry cooperation”. The discussion in this study highlights that while MBKM offers great potential in enhancing student skills, challenges such as faculty readiness, digital infrastructure, and institutional support still need to be addressed. Therefore, the results of this study provide important insights for higher education policy makers in designing more effective and sustainable MBKM implementation strategies.
