Abstract

Pencemaran sungai akibat akumulasi sampah dan pertumbuhan gulma air, khususnya eceng gondok (Eichhornia crassipes), dapat menghambat aliran sungai serta menurunkan efektivitas operasi Trash Skimmer Boat. Oleh karena itu, penelitian ini bertujuan merancang sistem Scissors Blade sebagai mekanisme pemotong gulma air yang terintegrasi dengan Trash Skimmer Boat melalui analisis struktur, perancangan sistem hidraulik, dan sistem kelistrikan. Penelitian dilakukan dengan memodelkan Scissors Blade menggunakan perangkat lunak CAD dan menganalisis 9 variasi desain berdasarkan kombinasi sudut kemiringan bilah dan panjang stroke menggunakan metode Finite Element Analysis (FEA). Parameter yang dianalisis meliputi Equivalent Stress, Total Deformation, Reaction Force, dan Safety Factor, dilanjutkan dengan perhitungan kebutuhan motor hidraulik, aktuator hidraulik, Hydraulic Power Unit (HPU), kapasitas genset, serta perancangan Piping and Instrumentation Diagram (P&ID) dan wiring diagram. Hasil penelitian menunjukkan bahwa konfigurasi Scissors Blade 70 × 70 × 60 mm merupakan desain yang dipilih karena memberikan kinerja struktur terbaik dengan nilai Equivalent Stress sebesar 46,20 MPa dan Safety Factor sebesar 5,31, sehingga masih berada di bawah tegangan luluh material dan aman untuk diaplikasikan. Berdasarkan hasil perancangan, sistem hidrolik yang terdiri atas motor hidraulik, aktuator hidraulik, dan Hydraulic Power Unit (HPU) telah memenuhi kebutuhan tekanan, debit, dan daya untuk mengoperasikan mekanisme pemotongan serta pengangkatan Scissors Blade. Hasil perhitungan juga menunjukkan kebutuhan daya listrik sistem sebesar 11,64 kW, sehingga dipilih genset berkapasitas 12 kW sebagai sumber tenaga. Selain itu, rancangan P&ID dan wiring diagram berhasil disusun sebagai acuan integrasi sistem hidraulik dan kelistrikan sehingga seluruh komponen dapat bekerja secara aman, terintegrasi, dan sesuai dengan kebutuhan operasional Trash Skimmer Boat. Penelitian ini diharapkan dapat menjadi referensi dalam pengembangan sistem pemotong gulma air pada Trash Skimmer Boat guna meningkatkan efektivitas pembersihan sungai dan mendukung pengelolaan lingkungan perairan yang lebih berkelanjutan.

River pollution caused by the accumulation of trash and the growth of aquatic weeds, particularly water hyacinth (Eichhornia crassipes), can obstruct river flow and reduce the effectiveness of the Trash Skimmer Boat’s operations. Therefore, this study aims to design a Scissors Blade system as a mechanism for cutting aquatic weeds that is integrated with the Trash Skimmer Boat through structural analysis, hydraulic system design, and electrical system design. The research was conducted by modeling the Scissors Blade using CAD software and analyzing nine design variations based on combinations of blade inclination angles and stroke lengths using the Finite Element Analysis (FEA) method. The parameters analyzed included Equivalent Stress, Total Deformation, Reaction Force, and Safety Factor, followed by calculations of the requirements for the hydraulic motor, hydraulic actuator, Hydraulic Power Unit (HPU), generator set capacity, as well as the design of the Piping and Instrumentation Diagram (P&ID) and wiring diagram. The research results show that the 70 × 70 × 60 mm Scissors Blade configuration was selected as the optimal design because it provides the best structural performance with an Equivalent Stress value of 46.20 MPa and a Safety Factor of 5.31, which remains below the material’s yield stress and is safe for application. Based on the design results, the hydraulic system consisting of a hydraulic motor, hydraulic actuators, and a Hydraulic Power Unit (HPU) meets the pressure, flow rate, and power requirements for operating the cutting and lifting mechanisms of the Scissors Blade. Calculations also indicate that the system requires 11.64 kW of electrical power; therefore, a 12-kW generator set was selected as the power source. In addition, the P&ID and wiring diagrams were successfully developed to serve as a reference for the integration of the hydraulic and electrical systems, ensuring that all components can operate safely, in an integrated manner, and in accordance with the operational requirements of the Trash Skimmer Boat. This study is expected to serve as a reference in the development of aquatic weed cutting systems on Trash Skimmer Boats to improve river cleanup effectiveness and support more sustainable aquatic environmental management.
