This research study aimed to analyse the influence of joint-well irrigation technology and windbarrier vegetation to the risk-production as well as to analyse the optimum resource allocation of conservation farming at coastal land influenced by risk-production. The research method applied in this study was a survey method. The location of study was along Samas coastal line in Yogyakarta Special Province, Indonesia. The risk-analysis technique used was maximum likelihood estimation method. The analysis of optimizing done by linier programming method by concluding variable of risk-production (windbarrier and joint-well irrigation technology).  The research findings concluded that conservation farming at coastal land was that farming done at coastal land aiming to get farming profit and conserve coastal land by cultivating windbarrier plants and providing joint-well irrigation system as well.  The analysis of risk-production concluded that variable of windbarrier on rainy season could significantly decrease risk-production against cultivating shallots worth 29.92%, eggplants worth 14.99%, and sweet potatoes worth 6.96% for every adding 1% of windbarier unit, while variable of joint-well only influenced toward risk-production on farming eggplants worth 2.61%. On rainy season 1, variable of jointwell influenced risk-production toward farming shallots worth 18,67% and sweet potatoes worth 20.07%, while variable of wind-barrier influenced significantly toward the farming shallots worth 21.63%, red chillies with 14.05% and sweet potatoes with 4.16%. On dry season 2, variable of joint-well only influenced risk-production on farming sweet potatoes with 13.69%, while variable of wind-barrier only infuenced farming shallots worth 28.21%.  Allocation of conservation farming resources at coastal lands by concluding variable of riskproduction (wind-barier and joint-well irrigation technology) has been optimal. Maximum income earned by farmers was Rp 11,647,110.-/year.  

Key words: optimising, risk-production, conservation farming, coastal land. 1
