Three decades ago, West Nusa Tenggara or Nusa Tenggara Barat (NTB) was a resource of Bali cattle meat, to either provides national supply or export. However, since the year 2000, meat supply from NTB has been limited and there has been decreasing Bali cattle productivity. Low productivity of Bali cattle has been caused by severals factors such as: traditional way, in a small scale number cattle, in a relatively small size of land with limitation of feed availability in raising cattle. On the other hand, rice straw which potential for cattle feeding, has been burned which may induce pollution. In addition, cattle manure was also thrown to the field or to the river which may spread parasites infestation. As a consequuence, under NTB condition, Bali cattle has low productivity, with high cost of raising. Application of mixed farming may lead farm efficiency by reducing feeding cost, by using rice straws and processing manure as organic fertilizer. Mixed farming may provide solution to NTB farmers by leading zero waste and by inducing environmental friendly (eco-farming). Under mixed farming system, in order to improve cattle production, appropriate technology are essential to be implemented. Hopefully, production of Bali cattle and others agricultural comodities may increase optimally. Finally, higher income can be obtained and farmers may have a better live.

Non-tidal swamp rice field in Poso contain total Fe in a very high amount, ranging from 1,16% to 2,26%. In a reductive or very reductive condition, Fe solubility will be extremely high beyond the level where paddy can tolerate, hence causing toxicity in paddy. Application of compost is expected to chelate Fe and form organic Fe to decrease toxic effect in paddy. A greenhouse experiment was done treatment by 5 ton/ha of straw compost and cocoa pod compost in various combination to non-tidal swamp rice field in Korobono Poso regency. Under this factorial treatment, the first factor was composition of compost (100% straw compost, 75% straw compost + 25% cocoa pods compost, 50% straw compost + 50% cocoa pods compost, 25% straw compost + 75% cocoa pods compost, and 100% cocoa pods compost), and the second factor was water management (saturated irrigation and intermittent), arranged under completely randomized design (CRD). The observed component was the level of organic Fe and available P in soil. The research finding showed that the application of compost to non-tidal swamp rice field in Poso increased the level of organic Fe and available P in soil. The level of organic Fe and available P in soil with saturated irrigation was higher than with intermittent irrigation. The increased organic Fe tended to increased available P in the soil in non-tidal swamp rice field in Poso.

Black rot disease which is caused by Xanthomonas campestris pv campetris is animportant disease on cabbage and so far could not be controlled satisfactory yet.Recently, people getting conscious the negative effect of applicating synthetic pesticidesand the importance of using biocontrol agents fo controlling pests because they arerelatively save and environmentally friendly. Bacteriophage is viruse that infectsbacteria. The use of phages for disease control is a fast expanding area of plantprotection with great potential to replace the chemical control and now prevalent.Phages can be used effectively as part of integrated disease management strategies.The relative ease of preparing phage treatments and low cost of production of theseagents make them good candidates for widespread use in developing countries as well.So far, in Indonesia bacteriophage exploration for development as biocontrol agents hasnot been conducted yet. On the other hand, Indonesia is one of view countries having alot of biodiversity resourches in the world. So it can be predicted that it is a lot ofbacteriophages strains naturally, which could be developed for biocontrol agents ofblack rot disease in cabbage. This research was aimed to isolate some bacteriophagevirulent to Xanthomonas campestris pv campetris from field. X. campestris pv campetris has been isolated from diseased cabbage in Blumbang, Tawangmangu.Biological characterization assay of 10 diseased cabbage leaf samples showed that allsample were indicated innfected by X. campestris pv campetris. Whereas plaque assayof 10 samples taken from fields showed indication of plague formation. This researchstill be continued to explore more samples form Tawangmangu, and also from othercabbage field in Central Java.

Growth of animal husbandry require to be supported by various production equipment, one of them is feed availability. Feed material source of energy come from corn, cassava, paddy bran, grist bran, sago and others, while feed materials source of protein come from soybeans by product, fish meal, leaf leguminous, blood flour and others. Feed materials contain fibrous are grass, paddy hay, sugar cane sprout, husk of cacao and by-product from agriculture food crop represent the feed materials which is exploited for the livestock of ruminants, like cattle, sheep or goat. Opportunity to use agriculture by-product as feed in livestock will represent the challenge and at the same time also to optimize local resources which during the time not yet been exploited efficiently. On the other side, animal husbandry has the constraint in the case of supplying the demand of meat and animal stock. Through the approach of LEISA (low external input sustainable agriculture), every hectare agriculture field can produce feed material for feeding 2-3 cattle. In this case, livestock personating as compost factory, together with crop by product, which is finally the compost utilized as organic fertilizer for crop. In the effort improving livestock population with the low production cost, pattern of integration between livestock with the plantation and forest, needs to be developed through technical, social and also economic. One of the success key from this pattern in there no materials which unused, and also exploiting innovate correctly and efficient. Through pattern applying integration crop and livestock by external approach of low input, will be provide a livestock product that have a competitive value. For the reason, in the future livestock production through the integration system with crop become enough to draw and have good enough opportunity to be achieved.

Egg is breed product that contains nutrients which easy to digest and exploited by the body. Egg is easily damaged and so it need to be preserved. One way to preserve is salted using sodium chloride (NaCl). The salt functions are to prevent the growth of bacteria, improve the taste and practical value. The longer it is ripened in the salting media, it will be more salty, because more salts are absorbed in the egg. The ewperiment was aimed tho know the NaCl content absorbed in the egg from salting media with various ripening time.Determination of NaCl content in the egg used Mohr Argentometric method i.e. the use of AgNO3 standard solution and K2CrO4 indicator. The determination of NaCl was done in duck eggs obtained from salting in week-0, 1, 2 and 3. Each treatment used 3 replications. The statistic used was one way analysis of varian (ANOVA) continued with SNK test.NaCl contents in the egg before salted were 0.34% in the egg white and 0.33% in the egg yolk. The NaCl content that was absorbed in the egg white from salting media after salted in week-1,2 and 3 were 2.77%, 3.71% and 5.09% respectively. While in the egg yolk the contents were 0.43%, 0.71% and 0.97% respectively. After statistically tested by one way anova and continued by SNK test it could be consluded that there was significant difference of NaCl content absorbed in the egg white and yolk from salting media inter-time of ripening.
