Abstract

Penelitian ini bertujuan untuk meningkatkan kualitas complete feed dengan penamb ahan bioaktivator terutama kecernaan bahan pakan. Materi dalam penelitian adalah complete feed. Penelitian dilakukan dalam 2 tahap yaitu tahap persiapan dan tahap analisis KcBK dan KcBO secara in vitro. Rancangan penelitian yang di gunakan adalah Rancangan Acak Lengkap dengan 5 perlakuan (T0, T1, T2, T3 T4) dan 4 ulangan. Hasil analisis ragam menunjukkan bahwa perlakuan penambahan bioaktivator mikroorganisme campuran pada complete feed berpengaruh terhadap KcBK dan KcBO secara in vitro.

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).

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

Abstract

The purpose of this study was to examine the influence of combined treatmentsof the extrusion process and the addition of a natural source of tannins (tea and orgambier wastes) of the total gas and methane production in soybean flour.The materials used in this study were soybean meal, tea waste, gambier, cowrumen fluid, alcohol, CO2, McDougall solution, 15% H2SO4, 0,5 N NaOH, 0,5 N HCl,1% PP indicator and distilled water. The instruments used were analytical scales, testtubes, oven, extruder machine, waterbath, centrifuge, vacuum flaks, CO2 gas cylinder,100ml syringes glass equipped with silicone hoses and clips to be closed and opened,vaccuntainer, erlenmeyergas chromatography, special flute tube and distillation flask,glass beaker, Erlenmeyer, incubator, pipettes, measuring instruments, magnetic stirrer,peristaltic pump to drain the rumen fluid and heater. This study used completelyrandomized design in 2x3 factorials and 3 replicates by a-factor (a0 = no extruided anda1= extruded) and b-factor(b0= no tannins, b1= tea waste tannins, b2= gambier tannin).The parameters observed including total gas and methane production, the data weretaseted by usisng analysis of varience and followed by the Duncan test.The results indicate that there is no interaction between the extrusion and theaddition of tannins to total gas production, while the production of methane gas does notindicate any influence (p < 0.05). It is concluded that the extrusion and protection withnatural tannins of soybean flour have impacted on decreased in the production of totalgas and methane production.

AbstractThe objective this study was to predict erosion rate and erosion hazard level in DumogaSub-watershed. The study is expected to provide spatial information on erosion rateand erosion hazard level in Dumoga Sub-watershed, particularly for spatial planning as wellas soil and water conservation. Erosion was predicted employing USLE while spatial analysiswas conducted using Geographic Information Systems (ArcView 3.3). Rainfall data were collectedfrom three weather stations, erodibility values obtained by analyzing samples fromthree soil types, slope categories were determined using DEM (Digital Elevation Model), valuesof the landuse and soil conservation were determined by means of satellite image interpretationin and field survey as well. It was found that soil erosion ranged from 0.39 to16.800 tonnes /ha/year. The lowest erosion rate occurred on forest land and ricefield withhacingflatslope. The highest erosion rate was identified on farm land having very steep slope.Erosion hazard level varied from verylow to very severe. It is necessary to perform soil andwater conservation measured on the land experiencing severe to very severe erosion hazardas to reduce soil erosion.Keywords: Erosion, Geographic Information System, Watersheed

Abstract

Cucumber (Cucumis sativus) is an important vegetable comodity in Indonesia, but its production rate is still low. One of the factors that cause the low productivity is plant diseases. Damping-off disease often causes the damage of cucumber plant caused by a fungus that lives in the soil as soilborne disease, Phytium sp. The controlling effort of this disease have been done, for example using Trichoderma sp. as bio-agent, but the utilization of the bio-agent still is not practical so it is difficult to be applied in field. The pellet formula is more effective to be implemented because of the small size and easily moved. The purpose of this research was to produce the pellet formulation with active material of Trichoderma sp.  with rich nutritious content, cheap and easy carrier. This research used two tests, in vitro and in vivo test.  The in vitro test used six different pellet formulations, DAT, UAT, TAT, PAT, DDS and ATS. The best formulation in in vitro test are UAT and DDS, then the formulas were used in in vivo test. Both formulas could suppress the pathogenic fungus, Pythium, in vivo test.

Abstract

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.
