Abstract

ABSTRAK. Air laut mengandung nutrisi yang dibutuhkan oleh tanaman. Tujuan penelitian adalah untuk mendapatkan informasi manfaat air laut untuk pertanaman kedelai. Penelitian dilaksanakan di lahan percobaan Fakultas Peternakan dan Pertanian Universitas Diponegoro Semarang. Materi adalah air laut dari Pantai Marina Semarang, dan kedelai lokal Grobogan. Penelitian menggunakan rancangan acak kelompok monofaktor delapan perlakuan empat ulangan. Perlakuan tingkat salinitas/EC (Electrical Conductivity) air penyiraman yaitu J0 = penyiraman air tawar; J1, J2, J3, J4, J5, J6, dan J7 berturut-turut adalah penyiraman air laut 1, 2, 3, 4, 5, 6, dan 7 mmhos/cm. Semua petak perlakuan menggunakan 8 ton/ha mulsa eceng gondok dan diinokulasi bakteri rhizobium. Parameter yang diamati panjang tanaman, jumlah daun, produksi berat segar dan bahan kering jerami, produksi biji, kadar protein kasar dan serat kasar jerami kedelai. Analisis ragam, menunjukkan penyiraman air laut hingga EC 7 mmhos/cm belum menunjukkan pengaruh yang signifikan pada pertumbuhan, produksi, maupun kualitas jerami kedelai dibandingkan penyiraman dengan air tawar. Penyiraman air laut EC 7 mmhos/cm menghasilkan rerata panjang tanaman 26,53 cm, jumlah daun 245,25 helai petiole, produksi berat segar jerami 2029,5 g/petak, produksi bahan kering jerami 235,05 g/petak, produksi biji kedelai 515,22 g/petak, kadar protein kasar jerami 12,63 %, dan kadar serat kasar jerami 48,78 %.Growth, production, and quality of soybean straw at various levels of sea water to support ruminant feedABSTRACT. Seawater contains nutrients needed by plant. The research aim was to get information the benefit of seawater for soybean. The research held in research field of Animal Husbandry and Agriculture Faculty, Diponegoro University Semarang. Seawater was taken from Semarang Marina Beach. Soybean was local bean of Grobogan. The experimental design used was a randomized block design eight treatment with four block.The factor was EC(electrical conductivity) level of watering diluted seawater namely J0 = Without sea water (fresh water); J1, J2, J3, J4, J5, J6, and J7 were EC level of watering diluted seawater of 1, 2, 3, 4, 5, 6, and 7 mmhos/cm respectively. All treatments using 8 ton/ha of water hyacinth mulch and inoculated of rhizobium bacteria. The parameters were plant length, number of leaves, seed production, fresh weight and dry matter production of shoot, crude protein and crude fibre content of soybean straw. Variant analysis, showed that watering sea water up to EC level 7 mmhos/cm has not shown significant influence on the growth, seed and straw production and quality of soybean straw compared to watering with fresh water. Level of watering diluted seawater EC 7 mmhos/cm yields plant length of 26,53 cm, number of leaves 245,25 pieces of petiole, weight production of fresh straw 2029,5 g/plot, weight production of dry straw 235,05 g/plot, weight production of seed 515.22 g/plot, 12.63% crude protein content, and a crude fiber content of 48.78%.

Abstract

(The quality and absorption efficiency of N at Centrosema pubescens (centro) and Pueraria phaseoloides (puero) cause add of iodine fertilizer)ABSTRACT. The aimed of the experiment was to know the effect of iodine fertilizer when applied to the soil on the quality and the efficiency of Nitrogen absorption of legume. Centrosema pubescens (Centro) and Pueraria phaseoloides (Puero), soil from Tenbalang, manure, an organic fertilizer ( N,P,K and KI ). H2SO4 solution, aquades, HCL, NaOH, indikator MR+MB, and blanko solution. The experiment also used 24 pot for plantation with 10 kg capacity , analytic balance etc. The experiment used 4 x 2 factorial completely randomized design. The first factor were Centro (Centrosema pubescens)- (L1) and Puero (Pueraria phaseoloides)- (L2) and the level of iodine fertilizer (I0) without iodine, I1 (iodine 5 kg/ha), I2 (iodine 10 kg/ha) and I3 (iodine 15 kg/ha) were the second factor. Application of iodine fertilizer has no significant result, to nitrogen absorption, nitrat reductase activity, crude protein contain, and fibre. In the other hand, the interaction between legume and iodine has significantly result on the efficient and absorption of nitrogen, crude protein. The conclusion showed that puero was more responsive than centro, however centro was more potential in efficiency and absorption of N and crude protein.

Abstract

The use of saline for rice cultivation needs to be support bytolerant rice varieties in saline land. The rice variety can be obtained through plant breeding programs, one of which is by physical mutation methods using gamma rays.. Physical mutation is random mutation, so we need to do selection after that treatment. Selection to get rice mutants that are tolerant of salinity stress can be done by planting on culture media that have been modified witt addition of NaCl.The perpose of this research is to examine the effect of gamma rays irradiation doses on rice callus induction and its tolerance level in saline media. This research used 2 designs, a monofactor complete randomize design at callus induction stage with a faktor in the form of gamma rays irradiation doses (0, 100, and 200 Gy) and factorial complete randomize designat the regeneration stage with a factor in form of gamma rays irradiation doses (0, 100 and 200 Gy) and the second factor is NaCl concentration (0 and 50 mM). The steps of this research were irradiation of Ciherang variety rice seed, making media for tissue culture, sterilization of rice seed explants, initiation of explants in callus induction media, subculture to regenerated media that had been modified with the addition of NaCl according to treatment, and then observation. The results showed that gamma rays irradiation could inhibit the growth of callus diameter and reduce the grofth of callus from explants of ciherang variety. All callus subcultured into regeneration media are unable to formbuds and turn black or die.
