Abstract

The high cost of fish feed has become the main problem in fish farming in Karangasem Village, Bulu District, Sukoharjo Regency. The “GP” Fish Farmers Group has long depended on commercial feed, which continues to increase in price and reduce profit margins. Meanwhile, local raw materials such as tofu waste, rice bran, and fish meal are abundantly available but have not been fully utilized due to the lack of processing technology. This community service program was carried out to implement a floating pellet machine as a solution to support feed self-sufficiency. The method consisted of three stages: preparation, implementation, and monitoring-evaluation. The preparation stage involved identifying partner needs and designing the pellet machine. The implementation stage included discussions, machine assembly, and feed production trials using local ingredients. Monitoring and evaluation were conducted through technical assistance and interviews with the group. The results indicate that the partners were able to operate the machine independently and produce floating pellets suitable for gourami and catfish farming. The use of this machine has proven effective in reducing feed costs, improving farming efficiency, and strengthening the group’s economic independence.

Abstract

The cutting blade used in pellet production machines directly affects the dimensional consistency of produced pellets. Polymer-based blades manufactured using 3D printing offer advantages in production cost and fabrication flexibility, but still have limitations in mechanical durability under repeated use. This study aimed to develop a cutting blade made of PLA (Polylactic Acid) using 3D printing technology with a 2 mm stainless steel reinforcement at the blade tip, and to evaluate its effect on pellet length stability in a pellet production machine. The blade was designed using SolidWorks and fabricated using Fused Deposition Modeling (FDM) with a 0.4 mm nozzle, 0.22 mm layer height, 100% infill, 60°C bed temperature, 210°C extruder temperature, and 4500 mm/min printing speed. Testing was conducted using a pellet machine operating at 70 rpm for 6 cycles, with 200 g of feed material per cycle and 8 pellet samples measured in each cycle. The results showed that the full PLA blade experienced an increase in average pellet length from 4.99 mm to 7.05 mm, while the hybrid blade only increased from 3.78 mm to 4.22 mm. One-Way ANOVA results indicated that testing cycles significantly affected pellet length in both the full PLA blade (F = 365.015; p < 0.001) and the hybrid blade (F = 61.255; p < 0.001). The study concludes that stainless steel reinforcement resulted in more stable pellet dimensions during repeated testing, compared to full PLA blades.
