Abstract

Mancozeb is a group member of dithiocarbamat fungicides that most widely applied in the field. The use of mancozeb causes residues that have negative effects on agricultural production system and on agricultural environment. This research aimed to obtain dark septate endophyte (DSE) fungal isolates that are tolerant to mancozeb fungicide. The study was consisted of three steps, i.e., the isolation of DSE fungi from chili roots, the effect of DSE fungal isolates on chili seeds, and the growth ability of DSE isolates on medium supplemented with mancozeb. Thirteen DSE fungal isolates were isolated from chilli pepper roots and grown in the field assumed to be contaminated by pesticides. The isolates of DSE fungi caused the growth of chili seeds were normal and abnormal. Seven DSE isolates were able to grow well at PDA medium suplemented with mancozeb at concentrations of 100, 200, 400, and 800 ppm with different levels of relative growth inhibition. Mancozeb on PDA medium influenced the mycelial growth and colony color of DSE fungal isolates. The biomass of DSE fungal isolates were reduced when they were grown at malt extract broth (MEB) medium suplemented various levels of mancozeb.

Abstract

Usaha peningkatan produksi ruminansia perlu diimbangi dengan penyediaan pakan hijauan secara kontinyu baik dalam segi kuantitas maupun kualitas. Namun sering kali peningkatan usaha produksi dihadapkan oleh ketersediaan jumlah pakan terutama pada saat musim kemarau. Oleh karena itu, perlu dicari pakan alternatif yang dapat digunakan untuk memenuhi kebutuhan ternak tersebut salah satunya dengan pemanfaatan limbah pertanian. Tujuan penelitian ini adalah mengetahui degradasi nutrien ransum dengan berbagai level jerami padi dan menentukan imbangan terbaiknya sebagai pakan ternak. Data a, b, c dan DT yang diperoleh selanjutnya dianalisis secara statistik berdasarkan rancangan acak lengkap (RAL) adanya pengaruh antar perlakuan pakan dilanjutkan dengan uji jarak berganda Duncan. Ransum perlakuan disusun iso protein kasar (PK) dan total digestyble nutrients (TDN) dengan kandungan 12% PK dan 64% TDN. Perlakuan level jerami padi yang digunakan yaitu P1=25%, P2=30%, P3=35% dan P4=40%. Ransum standar (P0) untuk pakan sehari-hari (PK 12% dan TDN 60%) digunakan sebagai pembanding nilai a, b, c dan DT dari keempat perlakuan tanpa diujikan secara statistik. Hasil penelitian menunjukkan bahwa terdapat pengaruh yang nyata (P< 0,05) fraksi a, b dan DT degradasi bahan kering ransum perlakuan sedangkan pada nilai c tidak terdapat pengaruh nyata. Pada degradasi bahan organik menunjukkan bahwa terdapat pengaruh yang nyata (P<0,05) pada fraksi a, fraksi b, nilai c dan DT.Kata Kunci : jerami padi, ransum, degradasi, in sacco

http://dx.doi.org/10.17014/ijog.vol3no4.20081Lithologically, the Nampurejo Pillow Lava, Kebo and Butak Formations, which are dominated by volcanic rocks, spread west - eastly, along the northern foot of the Baturagung Mountains. The Nampurejo Pillow Lava, which has an Early Oligocene age, is overlain by the Late Oligocene - Early Miocene Kebo and Butak Formations successively. The Nampurejo Pillow Lava consists of basaltic pillow-lavas showing pillow structures and they are intercalated by black sandstones. The Kebo Formation comprises alternating sandstone and pebbly sandstone with intercalations of siltstone, claystone, tuff, and shale. On the other hand, the Butak For- mation is composed of polymic breccia with intercalations of sandstone, pebbly sandstone, claystone, and siltstone/shale. The three units were deposited in a deep – shallow marine basin, which was filled by volcanic prod- ucts. Compared to the lower part of the Kebo Formation, volcanic activities during the deposition of the upper part of the Kebo Formation and the Butak Formation were more active.

Abstract

Ransum protein needs are influenced by the amount required for basic living,growth, and production. Cotton seed oilcake potential as a protein supplement foranimal feed because protein that present in cotton seed oilcake reaches 29.57 to31.13%. Cotton seed oilcake containing high protein and good quality given toruminants largely degraded by microbes in the rumen, so that influence to theefficiency of protein utilization. Protein is one of the important nutrients needed byruminants at various levels of production and the various phases of his life. A highprotein in feed ingredients needs to be done protection that are not easily degradedby rumen microbes Protection of proteins can be done in several ways, namelyphysical, chemical and biological. The study aims to assess fermentability feedingredients protein source that is protected by tannins from extracts of tea waste interms of measuring the concentration of NH3, Undegraded Protein and total proteinproduction. The results showed that the concentration of ammonia in cotton seedoilcake protected with increased of tannin levels decrease NH3 concentration andincrease the levels of UDP (p <0.05) and increase total protein. The average of NH3concentration, UDP and total protein in T0, T1, T2, T3 consecutive are (7,52 mM;10,91%; 369,62 mg/g), (6,60 mM; 11,45%; 439,50mg/g), (6,55 mM; 12,41%;457,35 mg/g), (6,32 mM; 13,44%; 514,95 mg/g). The conclusions of this study thatthe cotton seed oilcake protected dregs of tea tannin extracts with level 0,25%,0,50% and 0,75% can decrease the concentration of NH3, increase UDP and totalprotein. The protection level of Cotton seed oilcake with tannin extract the best teawaste is level 0,75% (% b/b BK).
