Scientific Concepts / Discoveries / Nature Phenomena Presented

Agricultural ecosystem / hydrology (Subak system)
- Subak is described as an organized water-management system for rice cultivation.
- It emphasizes collective regulation of water flow to help keep rice fields productive.
Plant/food processing phenomenon
- Threshing and winnowing as a sequence:
  - Rice separation from husk via grain-husk collision.
  - Wind-assisted winnowing that carries chaff away from the grains.
Ecology / landscape observation
- Bali’s rice terraces/fields, villages, and trees are presented as a dynamic “living landscape,” implicitly highlighting human–environment integration.

Trihikarana / trihitakarana (balance among realms)
- Maintains balance among:
  - Humans with each other
  - Humans with nature
  - Humans with the creator (divine/spiritual world)
Pura/ritual space and social structures
- Worship is performed through practices related to pura, particularly in the Subak area.
- Social organization includes roles (e.g., farmer associations) that regulate both water management and collective life.
Geometric/biological motif traditions in art
- Carvings feature floral and fauna motifs alongside geometric patterns, linked to Balinese Hindu mythology.

Winnowing and separation of rice
- Threshing separates grains from husk through collisions.
- Winnowing uses a light motion where wind carries away fine chaff.
Cremation procession / ritual sequencing
- People arrive carrying offerings.
- The decorated, cow-shaped coffin tower is rotated at crossroads to mislead evil spirits.
- The tower reaches the burning site; the fire is lit.
- Souls are believed to be lifted with the setting sun’s light toward nirvana.
