Rice straw is a byproduct formed during rice cultivation. Disposal of rice straw may happen via unhygienic methods such as burning, which is happening in Malaysia and other countries. This study aims to rid rice straw via an eco-friendly biodegradation technique. Biodegradation of rice straw depended on actinobacteria, which were isolated from the cultivated soil of rice and rhizosphere areas in Tabuk region. Out of thirty actinobacterial isolates, only three isolates (S-5, S-12, S-20) biodegraded starch, cellulose, lignin and rice straw powder. The most potent actinobacterial isolate (S-5) was identified as Streptomyces tendae, which effectively biodegraded all polysaccharides of rice straw. Biodegradation of rice straw was associated with a significant reduction in C/N ratio, where the latter fell from 30.4% to 17.2% within 42 d.

The Impact

Rice straw is an abundant resource that was still seen as a waste in intensive rice cultivation. Rice straw is said to be a resource because it can be used as organic fertilizer (compost) and contains nutrients that were beneficial for crop growth and soil fertility. The fact in the field was still found that rice straw was wasted, one of which was burned. A study was conducted through a method of observation and survey involving rice paddy farmers in 3 sub-districts in the district of Klungkung, namely Banjarangkan, Klungkung and Dawan. The aim of the research was to know the production of rice straw waste and the potential of wasted organic fertilizer in intensive rice cultivation. Based on the results obtained the production of dried straw waste in each harvest about 10.21 tons/ha.  Farmers do not utilize rice straw as compost by reason, not knowing how to composting. There were 30.34% of farmers who burn straw because based on the knowledge gained burn is an easy way to restore rice straw to the ground. The impact of burning rice straw was around 5,887,086 - 7,888.7 tons of organic fertilizer wasted.

Irrigation Method

Gemolong subdistrict in Sragen Regency of Central Java, Indonesia has a rainfed rice area of 2,047.64 hectares. Water is very limited during the dry season and this usually makes farmers use costly groundwater pumps for irrigation. This means conventional method involving the continuously flooded irrigation combined with chemical fertilizers which are considered water-wasteful and hazardous to the soil is the current practice in the area. However, water saving-irrigation with the addition of organic material has been discovered to be an alternative solution to this problem. Therefore, this study aimed to determine the effect of this method on water productivity using four variations of water-saving irrigation treatment and composition of organic application as well as one control treatment involving conventional method with chemical fertilizers. Meanwhile, composted rice straw was used as organic material and applied at 20% and 40% composition. The results showed the application of organic material boosted rice production while the water-saving method increased water productivity. Applying rice straw to the soil at 20% and 40% was discovered to have increased water productivity by 15% and 19% compared to the control treatment. Moreover, the application of 20% rice straw to water-saving irrigation method saved up to 19% water and increase its productivity by 16.5% in comparison with the control treatment. However, 40% under water-saving irrigation method reduced the water productivity by 2% even though it saved up to 27% water needed for irrigation. It is, therefore, recommended that water-saving methods added with 20% organic material be implemented as alternative rice cultivation procedures during dry season and period of water scarcity.

Organic Farming System

Introduction of organic rice-based rice cultivation technology package through demplot is done in Subak Sungi 1 using ciherang variety. The number of farmers participating in demonstration plots in organic cultivation of paddy-based rice cultivation were 5 people, with age of farmers aged greater than 55 years occupying the highest percentage (45.45%), with elementary education level (72.75%), followed by high school education (18.25%), and junior high (9%). The average farmland area is 34.63 acres, with self-owned status (55,94%), status as penyakap 41,18% and rent status 2,88%. The farmers' response to the organic rice-based rice planting assessment is quite high, as evidenced by the evaluation that 100% of farmers participating in demonstration plots know and understand about organic rice system cultivation, and they agree to develop this cultivation system in the future. Demplot research results can increase the yield components and weight of dry grain harvest per hectare. Organic rice-based rice cultivation technology EVAGRO able to increase production of dry grain harvest significantly with a value of 6.8 tons / ha. There is a tendency of dry weight value of ciherang varieties of 6.8 tons / ha giving highest but not significantly different with PGPR organic based technology.

Ingestive Behaviour

This study was undertaken to find ways of reducing the time taken by goats tobegin to eat an edible feed that they have not previously encountered. Experiment 1demonstrated that the time taken for goats (7-8 months old) to ingest an unfamiliar feed(rice straw) was shorter (4 days) when it was first offered to them in the presence offamiliar positive cues (the odor or flavor of juices extracted from previously eaten,nutritionally beneficial grasses), than if it was offered in the absence of such cues (10 days).In contrast, when the feed was offered in the presence of the odor of parasitised goat feces,the time to first ingestion was extended to 20 days. Experiment 2 showed that when sixmonthold goats were exposed to feeds they had not experienced previously (rice straw orrice bran) they did not ingest these feeds in less than 7 days. However, they commencedingesting these feeds immediately if they had been exposed to them, prior to weaning, inthe presence of their mother or another adult goat. Application of the principles of feedingbehavior, as illustrated by the present studies, to goats in Vietnam may improve theirproduction, especially when diets are changed frequently and include both familiar andunfamiliar materials.Keywords: Behavior; Diet selection; Flavor; Neophobia; Social facilitation; Goat.
