Dalam kegiatan ini, demonstrasi sistem PVD 3D dilaksanakan di Ming Chi University of Technology (MCUT) dengan melibatkan 10 peserta (n = 10) untuk meningkatkan pemahaman mereka mengenai teknologi pelapisan vakum. Melalui kegiatan praktik langsung, peserta memperoleh pengetahuan mengenai komponen sistem, persyaratan instalasi, sistem vakum, prosedur keselamatan, dan keseluruhan proses pengaturan sistem. Survei terstruktur untuk menilai pemahaman yang dilaporkan oleh peserta sendiri (self-reported understanding) dilakukan segera sebelum dan setelah demonstrasi. Rata-rata pemahaman yang dilaporkan sendiri meningkat dari 16,7% pada survei sebelum demonstrasi menjadi 93,3% pada survei setelah demonstrasi, yang menunjukkan peningkatan (knowledge gain) sebesar 76,6 poin persentase. Lebih dari 80% peserta melaporkan pemahaman yang komprehensif terhadap seluruh topik yang dievaluasi setelah kegiatan. Hasil ini menunjukkan bahwa demonstrasi tersebut berkaitan dengan peningkatan yang signifikan dalam pemahaman peserta yang dilaporkan sendiri mengenai teknologi PVD 3D.

Kampar Regency has great potential in the goat farming sector; however, farmers frequently encounter constraints regarding the limited availability of quality feed, particularly during the dry season. This Community Service Program aims to enhance the knowledge and skills of farmers in Penyasawan Village through training on alternative feed processing technology in the form of cassava leaf waste silage. The implementation methods encompass partner problem identification, socialization, theoretical counseling, and practical demonstrations of anaerobic silage-making over a period of 21 days. The activity results demonstrated an 80,7% increase in participant understanding, which is reflected by the rise in the average post-test score (82.4) compared to the pre-test (45.6). The resulting silage met good quality standards, characterized by a fresh acidic aroma, a non-slimy texture, and a pH range of 3.8 to 4.2. Economically, the adoption of this technology has the potential to save feed costs by IDR 450,000 to IDR 600,000 per month for 10 goats, while simultaneously supporting a sustainable farming system and a village-level circular economy.
