Abstract

Operasi trash skimmer boat pada perairan darat terutama sungai dan danau sering mengalami penurunan kinerja akibat material sampah yang saling menumpuk saat diangkut conveyor sehingga menimbulkan kondisi jamming sehingga menyebabkan operator melakukan penghentian opaerasi untuk melakukan pembersihan manual. Selain itu, keterbatasan ruang pemasangan komponen pada kapal menuntut rancangan unit pemotong tetap efektif untuk membantu proses pengambilan sampah tanpa memicu sumbatan. Penelitian ini bertujuan untuk merancang dan memodelkan alat bantu pemotong cutting drum blade berbasis hidrolik yang dapat diaplikasikan pada lengan hidrolik trash skimmer boat, meliputi penentuan kebutuhan daya, rancangan komponen hidrolik, serta rancangan geometri pemotong yang efektif. Metode yang digunakan pada penelitian ini mencakup pengumpulan data dimensi kapal, pemodelan geometri lengan hidrolik dan pemodelan cutting drum blade menggunakan SolidWorks untuk mendapatkan variabel gaya, dan perhitungan kebutuhan daya untuk mendukung pemilihan komponen sistem hidrolik. Kemudian diberikan validasi kekuatan rancangan model pemotong melalui simulasi Finite Element Analysis (FEA) pada Ansys Workbench dengan pembebanan gaya tangensial pada ujung gigi dan skenario variasi putaran drum, sudut masuk gigi pemotong terhadap benda kerja untuk mengevaluasi total deformation dan tegangan ekuivalen (von-mises) maksimum dari pemotong terhadap benda kerja. Dari hasil yang diperoleh dari perhitungan untuk mampu mengoperasikan lengan hidrolik dibutuhkan gaya dorong 5,84 kN dari actuator. Selain itu berdasarkan hasil simulasi didapatkan bahwa rancangan geometri pemotong yang efektif adalah mempunyai radius gigi pemotong terkecil, dan sudut gigi pemotong terkecil, dengan hasil simulasi tersebut mendapatkan torsi 303,8 N.m pada poros pemotong. Untuk mampu mendapatkan torsi pada poros pemotong dibutuhkan hydraulic motor yang didukung dengan flow rate 21 l/min dan pressure 200 bar untuk mencapai putaran kerja 65 RPM. Perancangan komponen hidrolik untuk pengoperasian cuttinng drum blade membutuhkan 3 actuator, 1 hydraulic motor, 2 directional control valve 4/3, 1 directional control valve 4/2, dan 1 Hydraulic Power unit didukung dengan Gear Pump 12 cc dan reservoir 60 Liter. Selain itu, penelitian ini juga menentukan genset minimal yang diperlukan sebagai sumber daya, yang ditentukan berdasarkan total kebutuhan penggerak 3 sistem pemotong pada trash skimmer boat. Kapasitas genset dihitung dipertimbangkan dari kebutuhan daya, faktor efisiensi, serta safety factor berdasarkan kebutuhan ketiga sistem pemotong trash skimmer boat, dengan didapatkan kebutuhan genset sebesar 12 kW untuk menunjang pengoperasian pemotongan pada trash skimmer boat.

Trash skimmer boat operations in inland waters, especially rivers and lakes, often experience a decline in performance due to waste materials piling up on the conveyor, causing jamming and forcing operators to stop operations to perform manual cleaning. In addition, limited space for component installation on the boat requires the cutting unit to be designed to remain effective in assisting the waste collection process without causing blockages. This study aims to design and model a hydraulic cutting drum blade cutting tool that can be applied to the hydraulic arm of a trash skimmer boat, including determining power requirements, hydraulic component design, and effective cutting geometry design. The methods used in this study include collecting ship dimension data, modeling the geometry of the hydraulic arm and cutting drum blade using SolidWorks to obtain force variables, and calculating power requirements to support the selection of hydraulic system components. Then, the strength of the cutter model design was validated through Finite Element Analysis (FEA) simulation in Ansys Workbench with tangential force loading at the tip of the teeth and scenarios of drum rotation variations and the angle of the cutter teeth against the workpiece to evaluate the total deformation and maximum equivalent stress (von Mises) of the cutter against the workpiece. Based on the results of the calculations, a thrust of 5.84 kN from the actuator is required to operate the hydraulic arm. Furthermore, the simulation results indicate that an effective cutter geometry design features the smallest cutting tooth radius and the smallest cutting tooth angle; these results yielded a torque of 303.8 N.m on the cutter shaft. To achieve this torque on the cutting shaft, a hydraulic motor with a flow rate of 21 l/min and a pressure of 200 bar is required to reach an operating speed of 65 RPM. The design of the hydraulic components for operating the cutting drum blade requires 3 actuators, 1 hydraulic motor, 2 4/3 directional control valves, 1 4/2 directional control valve, and 1 hydraulic power unit equipped with a 12cc gear pump and a 60-liter reservoir. In addition, this study also determined the minimum generator set required as a power source, based on the total power requirements of the three cutting systems on the trash skimmer boat. The generator set capacity was calculated by considering power requirements, efficiency factors, and safety factors based on the needs of the three cutting systems on the trash skimmer boat, resulting in a generator set requirement of 12 kW to support the cutting operations on the trash skimmer boat.
