A study that as aimed to elucidate farming and marketing efficiencies of indigenous and intensive poultry farming was carried out at Dusun Tengah District of Barito Timur Regency. One hundred fifty four farmers was grouped into two groups, i.e. ordinary farmers having traditional poultry farming and leading farmers having intensive farming. Fifteen samples were then randomly selected from each group summing 30 samples. Trader samples were determined using a non probability sampling method. Primary data was directly collected from farmer samples through interview. Data analyses covered farming feasibility that was measured using RCR (revenue cost ratio), effect of marketing cost that included costs of transportation, labour, retribution, risk and capital interest on profit of traders, marketing margin, vertical market integration and price transmission elasticity. Results of this study showed that intensive farming of indigenous poultry gave profit twice higher than that of traditional farming. However, intensive farming was more profitable than traditional farming. There were five marketing channels of indigenous poultry involving farmers and traders. The greatest margin distribution at most marketing channels was recieved by traders. Marketing costs simultaneously gave signicifant affect to profit made by traders. Price at farmer level with that of consumer level was not yet vertically integrated so that full competition of market structure has not developed

Aims of this research is to evaluate relation land suitable class by using class criterion according to different farm to production, rendemen and advantage of sugarcane crop. Criterion of land suitability perceived to cover climate, condition of root, retention of nutrion, availibility of virgin, condition of surface of farm with using two criterion is Djaenuddin et al. (2003) and FAO (1983). The result indicate that assessment of land sustainability use criterion of Djaenudin et al. ( 2003) yielded by correspondence among physical class, class produce and class of rendemen equal to 33,3 gratuity. While advantage class counted 41,6 gratuity good match for physical class but jar with with class produce and also rendemen. Accumulatively advantage class tend to compared to lower of physical class, class produce and advantage class. Assessment of land suitability use criterion of FAO (1983) at yielded by correspondence among physical class, class produce and class of rendemen equal to 8,3 gratuity. Advantage class counted 66,6 gratuity good match for physical class but jar with with class produce and also rendemen. Incompatible all result of assessment of class according to sugar cane crop farm among physical class, production class, class of rendemen advantage class and at set of usage of farm because of difference in stipulating of criterion according to and decision making in classification according to farm. Usage of farm quality as factor influencing and production of rendemen not yet complete included as farm criterion at Djaenuddin et al. ( 2003) and also FAO ( 1983)

The experiment was aimed to investigate the effect of grasses variety and organic matter on the morphology characteristic of Elephant and King grasses in Volcanic soil of Klakah village, Selo sub district, Boyolali regency. A completely randomized design in a series of 2 x 4 experiment, with 4 replications were used to arrange the experiment. The first factor consisted of two grasses variety: Elephant grass (R1) and King grass (R2). The second factors were kinds of organics matter: D0 (no organic matter); D1 (organic matter 5 ton/ha); D2 (organic matter 10 t/ha) and D3 (organic matter 15 t/ha). The results showed highly significant effect of dietary organic matter on the morphological characteristic of tiller total of Elephant and King grasses. Both treatments showed significant interaction (P=0.05) on tiller total. Dietary organic matter factor did not affect plant height of two kind of grasses, but significantly affected leaf and culm ratio. The kinds of grasses factor showed highly significant effect (P=0.01) on plant height, but significant effect on leaf and culm ratio. The organic matter increased number of tiller total on two kinds of grasses. King grass responded better than elephant grass on height plant and leaf and culm ratio. It is concluded that dietary organic matter at 5 t/ha could be recommended to be applied on volcanic soil
