ANALISIS PERKEMBANGAN SUMBERDAYA LAHAN PERTANIAN DAN KETAHANAN PANGAN DI PROVINSI DAERAH ISTIMEWA YOGYAKARTA
No full textThe one of development strategy and established of food security in Daerah Istimewa Yogyakarta (DIY) is using food production capacity development that related with optimize of the using of land resources. This effort has a opportunity to success remind that land resources in DIY has wet land as wide as 57.661 hectare and dry land as wide as 260.919 hectare, also un use shore land can be use for agriculture activities. There are many scenarios for to development these, such as 1) wet land and dry land intensification, and rising productivity acceleration of non optimal irrigated wet land, 2) extensification of shore land. Implementation of these scenarios needed supporting to solve technical and non technical problems, like controlling of agriculture land convertion, the wide of agriculture land that tend to limited. As a whole, the handling of land resources heed synergy cooperation inter sector in developing and needed political will from DIY goverment in filling food sufficient trough increasing of food production in DIY
KAJIAN FERMENTASI KACANG TANAH DARI HASIL EKSTRAKSI MINYAK DENGAN CARA PENGEMPAAN
No full textResearch on changes in physico-chemical and functional properties of flour partially defatted peanut with R. oligosporus and R. oryzae were conducted. Before fermentation hull peanut was extracting the oil by hydraulic press. The experiment was arranged in completely randomized design in two times, treatment consisted of five fermentation duration (0, 8, 20, 22 and 24 hours) and two starter (R. oligosporus and R. oryzae). The result showed that R. oryzae grow faster than R. oligosporus and has gray black mycellium. Optimum time fermentations was 22 hours and fermented peanut flour by R. oligosporus has physico-chemical and functional properties better than R. oryzae
PEMETAAN ALIH FUNGSI LAHAN PERTANIAN DENGAN GIS DAN REMOTE SENSING
No full textResearch aim are (1) to map using of farm present land use in Mojolaban district, (2) to know fast displace agriculture farm function year period 2000 up to 2007, and (3) to know factors causing the happening of displacing agriculture farm function by identifying using of farm after displace function. Displace agriculture farm function in Mojolaban district Sukoharjo regency known by determining wide of the each type land use farm in the year and then comparing them in next year. Mapping of land use farm agriculture as reference first time is Aspect Earth Map Bakosurtanal 2000 year. Mapping of land use type on 2003 got from IKONOS satellite that passes Google Earth media. Mapping of land use type on 2007 got with direct field survey, by using previous image and map as activity map. Result of the research indicate that (1) farming in Mojoloban district during range ot time 2000, 2003 and 2007 had displace farm function; land use field farm type from 2.615 ha (2000) decreased to become 2.562 ha (2003) and then decrease again become 2.549 ha (2007), non irrigated dry field type from 62 ha (2000) decreased to become 39 ha (2003)and then decrease again become 35 ha (2007), garden type from 22 ha (2000) decreased to become 18 ha (2003) and remain 18 ha (2007), and settlement type from 1.117 ha (2000) increased to become 1.198 ha (2003) and then increased become 1.215 ha (2007), and (2) factor causing displace agriculture farm function to non agriculture are increasing of resident population, agriculture sector failed to compete, desreasing of agriculture and basic facilities, higher rice selling price field by developer and strategic rice field farm situation
FORMULASI KOMBINASI OPTIMUM FAKTOR-FAKTOR PRODUKSI DALAM PENGEMBANGAN USAHA PETERNAKAN SAPI PERAH RAKYAT DI KABUPATEN KLATEN
No full textKlaten regency represent one of regency in Central Java province have big enough dairy cattle population. During six the last year shown that decreasing the amount of population and productivity. Related with dairy cattle productivity decreasing with the circumstance condition of daity cattle, feed and unfavourable livestock management from farmer. Farmer in management of livestock of dairy cattle hope to get highest earning. Small-big of the earning depended from amount product, price of product and production cost.The aims of the research are a) to know the level of optimum input use which can yield the maximum earnings, b) to know the change influence that happened at earnings in the event of change of coefficient of objective function. Basic method used in this reserach is descriptive. Determination of research area is purposive that is Klaten Regency with subdistrict Jatinom. And than taken two village are Bandungan and Kayumas. Farmer taken as sample in this research are farmer have adult dairy cattle. Every village taken are 20 respondent farmer of dairy cattle.The result of research shown that the maximum earnings can be reached in ranch of dairy cattle farmer of scale 5,62 UT of equal Rp 13.477.500 with the input use in the form of availibility of money for the capital of equal Rp 9.500.00, availibility of money for feed of equal to Rp 28.500.00 and availibility of money for medicine of equal to Rp 2.000.000. sensitivity analysis with change of coefficients objective function that are availibility of capital from 0,325-0,577, avalibility of money for feed from -0,121-0,362, avalibility of money for the IB from 0-0,388, avalibility of moneyfor medicine from 0,334-0,388, and availibility of water from 0-0,388 from optimal coefficient which still give the earnings for farmers
KAJIAN KELAYAKAN TEKNOLOGI USAHA TANI PADI SAWAH TADAH HUJAN DI MERAUKE PAPUA
No full textResearch aims are to study economic eligibility of rain paddy wet rice field with innovation use of certifiable seed, fertilization recommendation and application and also apart to plant. The research apply farmer rice field farm at dry season 2005 in Semangga Java village, Semangga district, Merauke regency. Source of data use collected primary data by record keeping and PRA. Data analysis conducted descriptively qualitative and quantitative use parsial budget analysis, with economic parameter of R/C, MBCR, TIP and TIH continued with sensitivity analysis. The result of research shown (1) component appearance result of technological introduction rain paddy wet rice field is better than farmer pattern, (2) rice field paddy introduction technology yield productivity 5,7 ton/ha while farmer pattern only reach 3,2 ton/ha, (3) applying technological package of rain paddy wet rice field can give advantage addition equal to Rp 8.347.274/ha with MBCR value 6,65, (4) rice field paddy survival technology still can stay in a condition to make-up of input price 25% and degradation of shell of rice price 15%. For the succes of applying technological innovation, needed medium support produce close to development location rice field with price which reached to be accompanied continuity adjacent
ABSORBSI NaCl PADA TELUR DARI MEDIA PENGASINAN DENGAN VARIABEL WAKTU PEMERAMAN
No full textEgg 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
