Abstract

Manual lifting of fertilizer bags in plantation operations often leads to musculoskeletal disorders (MSDs) among workers due to repetitive, high-load, and ergonomically poor movements. This study aims to design an ergonomic fertilizer lifting crane integrated into the Canycom S25A Fertilizer Spreader with a 650-liter hopper to reduce physical strain and improve operational efficiency. A hydraulic crane system was designed with dual-segment arms, four lifting hooks, and two hydraulic cylinders, actuated via the unit’s PTO engine. Ergonomic evaluation was performed using the REBA assessment tools. The simulation results indicated that the maximum stress on critical components was within safe limits, with a factor of safety above 1.5. Postural analysis showed a significant improvement, where REBA scores decreased from 12 to 2 after the crane was introduced. The design offers a reliable, low-cost, and easily manufactured solution that enhances worker safety, reduces ergonomic risk, and increases productivity in fertilizer loading processes, especially in rugged field environments. The crane can be adopted in various agricultural applications where safe material handling is essential.

Abstract

Pemerolehan bahasa pertama anak melalui proses yang bertahap dan berkesinambungan dengan melibatkan pengajaran maupun pembelajaran yang diperoleh dari bahasa ibunya dan lingkungan keluarga. Seiring berjalannya waktu dan pertumbuhan anak maka akan memperoleh bahasa kedua dari proses pembelajaran bahasa ketika di sekolah dan lingkungan sosial. Fonologi menjadi aspek penting sebagai awal dalam pemerolehan bahasa seorang anak. Penelitian ini bertujuan untuk mengkaji peran fonologi dalam pembelajaran bahasa anak dan penggunaan bahasa pertama dengan bahasa kedua bagi perkembangan bahasa yang efektif pada tahap berpikir kritis anak. Metode penelitian yang digunakan oleh penulis dalam penelitian ini adalah pengumpulan data kualitatif dengan mengumpulkan data melalui observasi dan wawancara kemudian menganalisis data. Hasil penelitian menunjukkan bahwa lingkungan yang aktif memberikan interaksi dengan anak melalui percakapan dengan masyarakat sekitar, teman sebaya, dan keluarga terutama orang tua. Anak cenderung memiliki kemampuan berbahasa yang baik namun dengan memperhatikan pada aspek pengucapan, pelafalan kata, dan susunan kalimat yang benar agar tidak terjadi kesalahan dalam penuturan kata. Pembelajaran bahasa yang efektif sangat penting bagi anak-anak, karena membantu mereka mengembangkan keterampilan bahasa dan meningkatkan keterampilan komunikasi mereka
