Abstract

3D asset optimization is a crucial challenge in game development because high-polygon models increase computational load, reduce frame rates, and negatively affect user experience in real-time rendering environments. This research addresses the problem by applying the Quadric Error Metrics (QEM) algorithm through the Decimate Modifier (Collapse Mode) in Blender as a solution for mesh simplification. Various high-polygon 3D models were simplified at different reduction levels and tested in the Unity engine to evaluate their impact on performance. The evaluation included frame rate measurement, vertex and triangle count reduction, and geometric accuracy assessment using the Hausdorff Distance method. The results show FPS improvements ranging from 9% to 41%, with vertex reduction between 8% and 33% and triangle reduction between 17% and 22%, while maintaining acceptable visual fidelity. These findings demonstrate that QEM-based optimization effectively balances visual quality and rendering performance, making it suitable for resource-constrained platforms such as mobile games and VR applications.

Abstract

Abstrak: Kegiatan pengabdian ini dilaksanakan bersama Kelompok Tani Hutan (KTH) Pring Sedapur Kabupaten Banyumas, yang memiliki potensi besar dalam budidaya lebah madu klanceng namun menghadapi keterbatasan produksi, legalitas usaha, serta strategi pemasaran. Memperkuat kapasitas teknis budidaya, meningkatkan nilai tambah produk melalui inovasi kemasan dan branding, serta mendorong transformasi pemasaran digital dan legalitas usaha. Selain itu, kegiatan ini juga bertujuan untuk meningkatkan hardskill dan softskill mitra, khususnya dalam kemampuan produksi serta pemasaran (branding dan digital marketing) agar lebih kompeten dan berdaya saing. Kegiatan dilaksanakan dengan metode gabungan yang meliputi pelatihan, ceramah, praktik langsung, pendampingan, dan evaluasi. Mitra kegiatan ini adalah Kelompok Tani Wanita (KWT) Cipto Roso beranggotakan 10 orang. Evaluasi dilakukan melalui observasi dan kuesioner pra–pasca kegiatan untuk menilai peningkatan kemampuan produksi dan pemasaran digital. Hasilnya menunjukkan adanya peningkatan keterampilan mitra sebesar 95% dalam aspek produksi dan pemasaran (branding dan digital marketing). Program ini memberikan dampak positif berupa penguatan ekonomi lokal, kemandirian usaha, serta terciptanya model pemberdayaan berbasis potensi desa yang berkelanjutan.Abstract: This community service activity was carried out with the Pring Sedapur Forest Farmers Group (KTH) in Banyumas Regency, which has great potential in stingless bee cultivation but faces limitations in production, business legality, and marketing strategies. Strengthening the technical capacity of cultivation, increasing product added value through packaging and branding innovation, and encouraging digital marketing transformation and business legality. In addition, this activity also aims to improve the hard and soft skills of partners, especially in production and marketing capabilities (branding and digital marketing) to be more competent and competitive. The activity was carried out using a combined method that included training, lectures, direct practice, mentoring, and evaluation. The partner for this activity was the Cipto Roso Women's Farmers Group (KWT) with 10 members. Evaluation was carried out through observations and pre-post activity questionnaires to assess improvements in production and digital marketing capabilities. The results showed a 90% increase in partner skills in production and marketing aspects (branding and digital marketing). This program has a positive impact in the form of strengthening the local economy, business independence, and the creation of a sustainable village potential-based empowerment model.
