Abstract

Centrifugal pumps are the main component in pumping systems that are widely applied in industry, agriculture, and practical activities in engineering laboratories. This study aims to design and build a centrifugal pump tester with single, series, and parallel configurations as a learning medium in the Mechanical Engineering Laboratory. This tool uses two National TRANS GP-125 pump units with a discharge specification of 30 L/minute and a power of 125 W. The research method includes the stages of design, fabrication, testing, and technical calculations including total head, major and minor pressure losses, and impeller dimension analysis. The test results show that the parallel configuration increases the discharge capacity, while the series configuration is superior in producing higher heads. The system efficiency reaches 69%, still within the standard range of pump efficiency (63–84%). This study produces interactive learning media that can help students understand the working principles of centrifugal pumps and the effect of system configuration on hydraulic performance.

Abstract

Modern technological progress has inspired numerous innovations that enhance efficiency in human activities, with agriculture remaining one of the most vital sectors for sustaining national economies. Appropriate technologies increase productivity while reducing dependence on traditional practices that demand excessive time and labor. This research presents the design and development of an agricultural drone created for seed spreading. The system employs a 300 Rpm DC motor that drives a propeller to ensure even seed distribution. Performance evaluation compared manual seed spreading and the drone-based method. Results demonstrated that manual spreading required an average of 3.33 hours per kilogram of seeds, whereas the drone accomplished the same task within 1 minute 20 seconds (80 seconds) per kilogram. These findings confirm that drone-assisted seeding offers an efficient and practical approach that supports the advancement of modern agriculture.

Abstract

This paper presents the experimental development and evaluation of a PIC16F877A-based intelligent controller for voltage regulation and load prioritization in standalone photovoltaic (PV) home energy systems. The proposed system integrates a photovoltaic panel, battery storage, inverter, and embedded controller into a unified platform for efficient energy management. The controller continuously monitors battery voltage using an analog-to-digital converter and implements a threshold-based control strategy to disconnect non-critical loads when the voltage drops below 11.7 V. Experimental results show that the PV system maintains stable voltage characteristics within approximately ±3%, while the output current varies significantly with solar irradiance, exhibiting fluctuations of more than 60% under varying environmental conditions. The proposed controller effectively regulates system operation by dynamically managing load distribution, thereby preventing deep battery discharge and improving overall system reliability. In addition, the integration of auxiliary subsystems, such as automatic lighting and motion detection, enhances energy efficiency by reducing unnecessary power consumption. The findings demonstrate that the proposed low-cost PIC-based controller provides a practical and effective solution for intelligent energy management in standalone PV systems, particularly in off-grid residential applications.

Abstract

Sugar palm (Arenga pinnata) sap tapping still relies on manual trimming of the inflorescence stalk surface using a machete. Although rotary cutting devices have been studied for several agricultural materials, quantitative evidence for a low-cost handheld machine specifically designed for sugar palm inflorescence stalk trimming is still limited. This study designed, fabricated, and evaluated a portable low-energy rotary cutting machine that integrates a rotary disc blade, DC worm gear motor, worm gearbox, rechargeable lithium battery, and protective blade cover. The novelty of the study is the task-specific evaluation of cutting time, operational capacity, energy consumption, battery-based trimming capacity, and prototype cost for smallholder sap tapping. Manual and machine-assisted trimming were compared using 20 repetitions for each method. The average cutting time decreased from 22.4 ± 1.1 to 6.8 ± 0.6 s/stalk, corresponding to a 69.64% reduction and 3.29 times faster operation than manual trimming. Operational capacity increased from 160.7 to 529.4 stalks/hour. The machine operated at 10.8 V and 0.95 A, requiring 10.26 W and 0.0194 Wh/stalk. A fully charged 10.8 V, 4.8 Ah battery can theoretically support approximately 2675 trimming operations before complete drainage. The prototype material cost was Rp 433,000, equivalent to approximately USD 24.25 using an exchange rate of Rp 17,856/USD. The results indicate that the developed device is a feasible low-cost and low-energy mechanization option for repetitive sugar palm inflorescence stalk trimming.
