KUALITAS AIR IRIGASI PADA KAWASAN INDUSTRI DI KECAMATAN KEBAKKRAMAT KABUPATEN KARANGANYAR
Get PDFSubdistrict Kebakkaramat was the region with the most extensive area of rice fields and the highest rice production, in addition to the Subdistricts Kebakkramat a number of industrial areas with the greatest number two after Jaten Subdistricts. Industry in the Subdistrict Kebakkramat is dominated by the textile industry and agriculture are mostly located in areas suspected of liquid waste that contaminate irrigation water for paddy soil. Pollution caused by industrial waste, will reduce the quality of irrigation water. The purpose of this study was to determine the quality of irrigation water in the industrial area Subdistricts Kebakkaramat. This research used descriptive quantitative method implemented through field surveys and continued by laboratorium analysis. Observation variables of the quality of irrigation water include temperature, TDS, pH, DHL, DO, nitrate and metals Cr. The results showed that the TDS, pH, DHL, DO and nitrate water still in suitable with the irrigation water quality standards according to Government Regulation No. 82 of 2001, while the temperature in point 5 does not correspond to irrigation water quality standard. Cr at all observation points, except the control does not correspond to irrigation water quality standard, that exceeds a predetermined limit is 0.01 ppm

No full textPenelitian ini bertujuan untuk mengetahui sistem pemangkasan dan aplikasi GA3 terhadap hasil buah anggur kultivar belgi. Penelitian ini dilakukan, di desa Glonggong, Gondang, Sragen, Jawa Tengah. Pada ketinggian tempat 78 m dpl. Dengan suhu rata-rata harian berkisar antara 25-30 derajat celcius. Jenis tanah regosol. Pelaksanaan penelitian dimuai pada bulan Agustus hingga Desember 2001. Penelitian ini disusun secara factorial dengan rancangan dasar rancangan acak lengkap dengan tiga kali ulangan. Adapun faktor perlakuannya adalah pemangkasan dan konsentrasi GA3. Hasil penelitian menunjukkan bahwa: sistem pemangkasan tidak memberikan pengaruh terhadap hasil buah anggur baik dari segi kuantitas maupun kualitasanya. Sedangkan pemberian GA3 konsentrasi 100 ppm dapat meningkatkan panjang malai bunga yang sangat berarti (meningkat hampir 2 kali dibanding panjang malai perlakuan kontrol); menurunkan jumlah biji per 100 g buah (menurunkan jumlah biji 43,58%); cenderung meningkatkan berat buah per tandan sebesar 33,37% dan jumlah buah per tandan sebesar 24,34%

The result of research was (1) There isn’t really impact to very really impact at the treatment of the fruit sstting to change colour, hardness and removal weight in packaging during transportation, (2) There isn’t really impact to very really impact at the treatment of kind of packaging to change colour and removal weight during transportation, (3) Packaging that been made from bamboo (basket) giving a the best of value was compared the others packaging to hardness of mango fruit during transportation
Faktor-Faktor yang mempengaruhi Petani dalam Penggunaan Benih Berlabel Bahasa Asing (BBBA)
No full textTo increase product need the existence of preeminent seed, because seed represent one of the crop conducting medium having role which very determine in the effort increase product and quality of crop conducting result. Seed claimed to be gilt edged where usage of seed with quality for supported by technological medium going forward other will be able to yield maximal productive crop. The farmers often loss their energy and also time in usage of seed which its unfavorable quality.The aimed of this research is to know how accurate factors such as wide of farm, education, seed price, and manure to influence farmer using BBBA (seed in foreign language’s label) at Sukoharjo District. Framework idea in this research is at taking an action, to buy and also use something, farmer will influence by immeasurable of factor, internal and external factor. Internal factor is direct related factor in accurate matter, and external factor related to BBBA consumer. In this research which the included in internal factor is BBBA it self price and usage of manure, while external factor of wide of farm mastered by farmers cultivated melon, formal education and of them.Sample area was selected by purposive pursuant to usage of farm many by farmer for the conducting of melon. Sample taken by counted 60 person who is taken at random. Data analysis is doubled linear regression.Result of regresi analysis mention that at confidence level 95% passing Test F obtained that accurate variable-variable by together mount usage of BBBA, where R2 value equal to 0,601 meaning that variation of usage BBBA influenced by free variable in model equal to 60,1%. And through Test T variable having an effect on wide of farm, Manure anad education with biggest influence sequence is usage of manure, later than education and wide of farm. While BBBA itself price in the reality do not influence farmer in using the BBBA product
Aplikasi Sistem Informasi Geografi (Gis) untuk Pemetaan dan Simulasi Erosi Tanah
No full textThe aims of the research are to use the technology of the geographic information system for mapping and simulation of the soil erosion, and to know the difference betweet actual and potential erosion on the spesific land use type. The area of the research is Jumapolo District, Karanganyar Regency. USLE equation method (R=R.K.L.S.C.P) was used to predict the soil erosion intensity. The steps of the research are (1) pre-survey, prepared equipments for suvey, (2) survey, was done by exploring predertemined land map unit, and (3) labs, analysis of the soil samples, the rainfall data and teh ArcView GIS. Analysis was done using rating based on Zachar (1982) in order to know the difference of the soil erosion intensity.The results of the research are first, geographic information system is useful to mapping and simulation of the soil erosion, especially to calculate data that numerous and difficult, to overlay, to layout the map (or the other spasial data) and the statistic of land area, second, Jumapolo District has variability of the soil erosion intensity i.e. very slight 25,77 ha (0,62% of the agriculture land area), slight 815,71 ha (20,39%), moderate 1.094,69 ha (25,49%), severe 1.150,58 ha (33,09%), very severe 827,25 ha (18,88%) and catastrophic 243,69 ha (1,53%) and third, the change of the land unit type and the conservation technic can change the soil erosio intensity. Simulation process result that land area which have soil erosion intensity severe, very severe and catastrophic changes become slight and moderate, therefore the new compotitions of the soil erosion intensity are very slight 25,77 ha (0,62%), slight 1.665,48 ha (40,06%), moderate 2.466,43 ha (59,32%), and each severe, very severe and catastrophic 0 ha (0%)
POTENSI AZOLLA SEBAGAI SUBSTITUSI PUPUK KANDANG PADA BUDIDAYA PADI ORGANIK
Get PDFOne of problems faced by farmers in the rice cultivation with organic system is organic fertilizer limited, especially for farmers who do not have livestock. Azolla is one of materials that can be used as organic fertilizer. The aim of the research was to determine whether Azolla (Azolla mycrophylla L.) is able to meet the nutrient needs of some rice varieties on organic rice cultivation. The experiment used factorial complete randomized block design with three factors and three replications. Azolla was spread at days after transplanting and at 25 days after transplanting, 75% of Azolla was incorporated into soil and the rest was left up until rice were harvested. Meanwhile, cow manure was distributed after tillage. The treatment consisted of rice varieties (Mira1, Mentik Wangi and Red and White), Azolla (0 and 2 tons / ha) and manure (0 and 10 tons / ha). The result showed that Azolla did not significantly increase growth and yield of rice, despite it could increase the N uptake 5,4% and P uptake P 17,3% , weight of dry straw, dry grain and 1,000 seeds by 5,86%, 12.7%, 7.37% than without Azolla respectively. Azolla 2 tons/ha with manure 10 tons/ha were able to increase N uptake by 7.6%, the uptake P by 13.7% and the of productive tiller number by 9.88%. From the standpoint of crop yields with organic system, a single use of Azolla has not been able to replace manure.
