Abstract

This study aims to determine water patterns available in different growing media. The study consisted of four treatments namely P1: rice husk charcoal media, P2: cocopeat and compost mix media with 2: 1 ratio, P3: soil and compost mix with 2: 1 ratio and P4: soil media. Field capacity for the entire treatment P1, P2, P3 and P4 from week 2 to week 12 in a row was 77,21% to 80,00%, 50,22% to 52,56%, 42,83% to 44,24%, and 36,70% to 37,95%. Temporary wilting point for all treatments P1, P2, P3 and P4 from week 2 to week 12 in a row was 36,59% to 18,99%, 29,09% and 10,63%, 10, 83% to 5,27% and 10,62% to 6,50%. Available water for strawberry plants for all treatments P1, P2, P3 and P4 from week 2 to week 12 in a row was 7,90 cm to 10,93 cm, 4,27 cm to 7,13 cm, 5,90 cm to 6,84 cm and 4,84 cm to 5,44 cm.

Abstract

Subak is a traditional irrigation organization in Bali, one of whose functions is to manage irrigation. Operation and maintenance (O&P) of irrigation networks is an activity involving monitoring and cleaning irrigation networks in subak. The purpose of this research was to determine the physical performance of irrigation networks and the operation and maintenance (O&M) system of irrigation networks at three subak sites located in Catur Angga Batukau, one of the World Cultural Heritage sites. The methods used in this research were survey and observation methods. The collected data were assigned weighted values and analyzed. Subak was assessed using three criteria, namely Good = 3, Medium = 2, and Less = 1. System analysis was conducted using a fuzzy logic approach. The results of the analysis indicated that the performance of the irrigation network at Subak Jatiluwih was 2.49 (medium), Subak Tengkudak was 2.42 (medium), and Subak Rejasa was 2.50 (medium). From the three subak sites, the results showed that subaks in Catur Angga Batukau were in medium condition; therefore, there is a need to increase maintenance of the irrigation networks.
