Abstract

This study aims to analyze the relationship between electron beam energy and electric charge, as well as the relationship between deviation and energy, to evaluate the output stability of the LINAC machine. Measurements were conducted at BPAFK Surabaya using a Varian TrueBeam LINAC at Hospital X, East Java. The study employed electron energies of 6 MeV, 9 MeV, 12 MeV, 16 MeV, and 18 MeV. The procedure included filling the water phantom with distilled water, setting the source-to-surface distance (SSD) to 100 cm with a radiation field size of 10 cm × 10 cm, and connecting the detector to the electrometer outside the LINAC room. Calibration was performed at the reference depth (Zref) based on the R₅₀ value from the Percentage Depth Dose (PDD) table according to the IAEA TRS-398 standard. Measurements were repeated five times with voltage variations of +300 V, −300 V, and +75 V. The results showed that the maximum electric charge occurred at 12 MeV at a depth of 2.96 cm, while the highest deviation, −0.15%, was observed at 16 MeV—still within the ±2% tolerance limit. Therefore, the LINAC machine is considered stable and suitable for use in radiotherapy.

Abstract

MSMEs chips in Jajar Village still manually layer seasoning, resulting in long processing times, high operator workload, and inconsistent quality between batches. This community service program aims to shift the process to a hexagonal seasoning mixer while simultaneously instilling discipline in operation-maintenance (PM) SOPs to increase efficiency and quality consistency. The activity implementation method includes needs mapping, SOP-module preparation, training (theory, demonstration, practice), coaching on the production floor, and pre-post evaluation. Instruments include pre-post knowledge tests, operator skill checklists, and process indicator measurements (productivity, CV of seasoning homogeneity, seasoning defects, setup time, unplanned downtime, and SOP/K3 compliance). The results showed a relative increase in operator knowledge of 63.6% (55% → 90%) followed by simultaneous improvements in process indicators: productivity increased by 29.1% (28.5 → 36.8 kg/hour), coefficient of variation (CV) of homogeneity decreased by 35.6% (17.4% → 11.2%), seasoning defects decreased by 57.6% (8.5% → 3.6%), setup time decreased by 31.5% (16.5 → 11.3 minutes), unplanned downtime decreased by 38.7% (62 → 38 minutes/day), and SOP/K3 compliance increased by 32.4% (68 → 90). These results indicate that the combination of technology transfer, SOP standardization, preventive maintenance, and operational parameter assistance on the production floor is effective in increasing efficiency while maintaining quality consistency. This intervention is aligned with Asta Cita—specifically missions 3 (encouraging entrepreneurship and creative industries), 4 (developing human resources), 5 (downstream and industrialization), and 6 (building from villages), and supports the SDGs: SDG 8 (decent work & economic growth), SDG 9 (industry, innovation & infrastructure), SDG 12 (sustainable production & consumption), SDG 3 (health & well-being), and SDG 17 (partnerships).
