Abstract

Penggunaan pestisida kimia secara terus-menerus memberikan dampak negatif terhadap lingkungan, seperti pencemaran tanah dan air, munculnya resistensi hama, serta terganggunya keseimbangan ekosistem. Salah satu alternatif yang dapat diterapkan adalah penggunaan pestisida organik berbasis metabolit sekunder yang dihasilkan oleh mikroorganisme, seperti Trichoderma sp. dan Pseudomonas sp. Proses produksi metabolit sekunder memerlukan mesin shaker yang mampu menghasilkan gerakan pengguncangan secara stabil sehingga kondisi fermentasi dapat berlangsung secara optimal. Penelitian sebelumnya telah berhasil merancang dan membangun mesin shaker untuk produksi pestisida organik, namun masih diperlukan penyempurnaan pada mekanisme penggerak guna meningkatkan kestabilan gerak dan keandalan mesin.
Penelitian ini bertujuan untuk melakukan rancang ulang mekanisme mesin shaker berkapasitas 10 liter agar menghasilkan sistem gerak yang lebih optimal. Metode penelitian dilakukan melalui analisis kinematika mekanisme, analisis gaya pada mekanisme, analisis crank-slider, serta analisis sistem transmisi belt dan pulley. Hasil dari setiap analisis digunakan sebagai dasar dalam mengevaluasi kinerja mekanisme hasil rancang ulang. Hasil penelitian menunjukkan bahwa sistem transmisi mampu menghasilkan putaran poros utama 135 – 150 rpm memerlukan putaran motor sebesar 885 – 984 rpm sesuai dengan kebutuhan mesin shaker. Mekanisme crank-slider menghasilkan gerakan bolak-balik yang stabil, sedangkan hasil analisis gaya dan tegangan menunjukkan bahwa komponen utama masih bekerja dalam batas aman. Dengan demikian, rancang ulang mekanisme mesin shaker berhasil meningkatkan kestabilan dan keandalan sistem penggerak sehingga mampu mendukung proses produksi pestisida organik secara lebih optimal.

The continuous use of chemical pesticides has caused various negative impacts on the environment, including soil and water contamination, the development of pest resistance, and the disruption of ecosystem balance. One environmentally friendly alternative is the use of organic pesticides based on secondary metabolites produced by microorganisms such as Trichoderma sp. and Pseudomonas sp. The production of these secondary metabolites requires a shaker machine capable of providing stable shaking motion to ensure optimal fermentation conditions. A previous study successfully designed and developed a shaker machine for organic pesticide production; however, improvements to its driving mechanism are still required to enhance motion stability and machine reliability. This study aims to redesign the mechanism of a 10-liter shaker machine to achieve a more optimal motion system. The research was conducted through kinematic analysis, force analysis, crank-slider mechanism analysis, and belt and pulley transmission system analysis. The results of these analyses were used as the basis for evaluating the performance of the redesigned mechanism.
The results show that the transmission system is capable of producing the required rotational speed for the shaker machine. The crank-slider mechanism generates a stable reciprocating motion, while the force and stress analyses indicate that the main components operate within safe working limits. Therefore, the redesigned shaker machine mechanism provides a more stable and reliable driving system, making it suitable for supporting the production process of organic pesticides.
