Abstract

One of the factors that can affect the performance of a dosing pump motor is the current and voltage supplied to the motor. Optimal variations in current and voltage can increase the fluid flow rate and dosing accuracy, while mismatches can lead to instability during operation. This experiment aims to reveal how changes in current and voltage affect the performance and efficiency of a dosing pump motor. The method used for data collection is an experiment on the observed object, namely a three-phase 380 Volt, 60 Hz, 3360 rpm induction motor of a dosing pump, by conducting tests and measurements of current, voltage, power, and stroke adjustment (valve) variation on the dosing pump during production. Based on the results, at a valve angle of 10°, the lowest setting, the voltage was 360 V and the current was 1.8 A, producing a motor power output of 102.8 Watts and a power factor of 0.42. When the valve was increased to 100°, the voltage was 380 V and the current rose to 5.70 A, resulting in a power output of approximately 2,166 Watts and a power factor of 0.0384, indicating that the motor's efficiency did not reach a power factor of 1. The variation in stroke adjustment (valve) on the dosing pump motor affects the current, voltage, and power output of the motor. Higher current and voltage are required by the motor to drive the dosing pump, as pumping fluid at a higher flow rate requires more power.

Abstract

This research aims to design an Adjustable Spreader Bar Telescopic that has high flexibility to adjust the needs of lifting loads in the long range of 3.48 meters to 4.27 meters. The design is carried out to provide solutions to the needs of the industry in lifting heavy loads with an optimal level of safety and efficiency. The research method involves several stages, starting from making geometric designs using CAD software, determining and entering the properties of the materials used, as well as modeling and simulation with the help of finite element analysis (FEA) software using ANSYS. The material used in this study is ASTM A992, which has high tensile strength and good deformation resistance. The simulation results show that the design of this telescopic bar spreader is able to withstand loads of up to 300 tons. In the simulation test, the minimum deformation was recorded at 0 meters, while the maximum deformation reached only 0.00031851 meters. The equivalent stress in the load has a minimum value of 9.7863 Pascal and a maximum of 3.1404 × 10⁸ Pascal. This value is still below the yield strength limit of ASTM A992 material, so the design is declared safe and feasible for application in the field. This research proves that the designed Adjustable Spreader Bar Telescopic is not only able to meet the needs of lifting loads with high capacity, but also has the flexibility of length that varies as needed. This advantage makes it an innovative solution for use in construction, logistics, and heavy industry projects that require lifting equipment with high performance and guaranteed safety.

Abstract

Procedure for Issuing a Container Release Order (SP2) in Improving Depot Service Efficiency at PT. Prima Indonesia Logistik Belawan / Maria Christina Lumbanraja / Nit.2201005 / Department of Commercial Shipping and Port Administration – Politeknik Adiguna Maritim Indonesia Medan 2025. The preparation of this paper is intended to conduct an in-depth study of the procedures for issuing Container Release Orders (SP2) and to assess their impact on the efficiency of depot services at PT. Prima Indonesia Logistics Belawan. The SP2 is a vital document that serves as official authorization to release containers from the depot to their final destination, and the issuance mechanism largely determines the smooth flow of logistics. In practice in the field, delays and inaccuracies in SP2 procedures often lead to long queues, operational congestion, and a decline in service quality. The author uses a qualitative approach through direct observation or field research, supplemented by library research to strengthen the analysis. The findings indicate that the biggest obstacles to SP2 issuance lie in the slow data verification process, limitations in digital systems, and weak coordination between departments. Therefore, improvements in operational standards, integration of information systems, and enhancement of human resource capacity through training are needed. With these improvements, the container release process is expected to be faster, more accurate, and capable of supporting smooth logistics distribution overall.
