The highest evapotranspiration (ETo) occurred in August with 3.95 mm/hr and the lowest one was in june with only 2.91 mm/hr. Effective rainfall of paddy crop refered to Table 1 whereas for palawija was Table 2. Soil tillage that lasted for 35 days, requirement of water ranged 2.29-2.67 mm/hr (refer to Table 3). To gain Total irrigation efficiency (e) of 65%, water required for cropping patterm paddy-paddy palawija that planted in August is 2.67 mm/hr (NFR), 0.3090 lt/ha (DR). Whereas, the water debit planned for main channel is 0.50 lt/dt/ha, 0.40 lt/dt/ha for secondary channel,and 0.35 lt/dt/ha for tertiary channel. Furthemore, the dimension (H) for main channel was 1.00 m, subsequently 0.55 m for secondary channel and 0.45 m for tertiary channel.Key words : Crop water requirement, Land preparation
KERUSAKAN TIPE EKOSISTEM KARST DAN PENGARUHNYA TERHADAP PERUBAHAN IKLIM (SUATU PENDEKATAN TEORI)

H SihombingFakultas Kehutanan, Universitas MulawarmanSamarinda ABSTRACTKarst ecosystem poses high economic potency however its attention was lack due to to date only pay attentions merely on mineral resource potency, and its conservation measure only focus to some extent on cave. Mean while, karst area owns wider protective function, such as water conservation, state revenue from tourism, mining, bird nest, even it closely relates to the national security issue and state intelligence. Pay an attention on karst ecosystem that covers biotic potency and mineral energy exploration is tought to be far from seriousness meanwhile its tension on this ecosystem tends to be larger, even already comes to the stage of ecology endanger. In relation to the global temperature rise that leads to the climate change, natural karst ecosystem seems pay a big role in reducing carbondioxide through karstifikasi process. Therefore, the karst ecosystem conservation is an urgent agenda.Key words : Karst, Ecosystem, Climate change

Tri GunartiningrumSekolah Tinggi Ilmu Pertanian (STIPER) Kutai TimurSangatta ABSTRACTFish are the source of animal protein which are needed by human beings for their intellectual growth and development, especially for who are still in the growth period. The demand of fish is more increasing within society’s awareness to consume food with hight nutritious and protein. This research was aimed to identity: 1) factor influencing the demand of fresh fish 2) commodities which have substitution and complementary relation toward demand of fresh fish and 3) trend of fish’s demand in 2003-2007 inDaerah Istimewa Yogyakarta. The research employed basic descriptive analysis. The secondary data of time series were collected from many sources. The multiple regression was used to analyse factor that influenced demand of fresh and trend analysis was used to know trend of demand. Research results showed factors influencing demand fresh-water fish are: socienty’s income, number of household’s head, price of fresh-water fish, price of salt-water fish, price of chiken, and price of rice. Factors influencing the demand of salt-water fish were number of household’s head price of fresh-water fish, price of salt-water fish and price of chiken. Based on the trend analysis, it was found that for the next five years, the demand of fish in Daerah Istimewa Yogyakarta will get more increasing.Key words : Demand, Substitution, Complementary
