This study was aimed to assess the effect of the addition of putak meal (as a source of carbohydrates) and rumen content (as a source of enzymes) in the making of C. odorata silage to the total content of tannins and nutrient content of C. odorata silage. The treatments were: CO (C. odorata), COP (C. odorata + 10% of putak meal), COPR5 (C. odorata + 10% of putak meal + 5% of rumen content), and COPR10 (C. odorata + 10% of putak meal + 10% of rumen content). The experimental design used was Completely Randomized Design, with 4 x 2 factorial patterns. The first factor was the treatment (CO, COP, COPR4, COPR10) and the second factor is the silage fermentation time (0 days and 21 days). Each treatment was replicated 4 times. The variables measured were concentration of total tannin content and nutrient content. The results showed that the addition of (10% of putak meal and 10% of rumen content) decrease total tannins of the silage by 15.50%. The nutrient content (OM and OP) increased by 3.45% and 41.81% respectively as well as a decline in crude fiber 3% when compared to the silage without additives. Fermentation time of C. odorata silage for 21 days produced the best quality silage fermentation time compared to 0 days.

Cultivation of the Elephant Grass cv Taiwan with tissue culture requires an acclimatization stage, therefore this study aims to find the best planting media and the effect of plant age and evaluation of production elephant grass cv taiwan mutant and nutrient content. Acclimatization was carried out in a greenhouse using sand, soil, and a combination of 50% sand with 50% soil, and the mutant type T2, T4 and K4. The acclimation process uses the Factorial RAL method with factor A type of mutant and factor B type of planting media and the parameters assessed are leaf length, number of leaves and plant mortality rate. Production evaluation uses the RAL method and the parameters observed to see elephant grass production are plant height, stem diameter, leaf width, number of tillers and amount of plant biomass production. Proximate analysis is used to show the nutritional value of plants that have been selected individually using scoring assessments. The results of the acclimatization study showed that the planting media that had the lowest mortality rate were sand and soil combination media (22%) followed by soil planting media (27%) and the planting media that had the highest mortality rate was sand media (30%). The results of the production evaluation stage showed that the highest average harvest weight was found in T4 mutants with an average weight of 1353 g clump-1harvest-1, followed by T2 mutants which had an average of 1198 g clump-1harvest-1 and the lowest harvest weight was found in K4 mutants with an average of 1002 g clump-1harvest-1. Based on the research results obtained the best planting media for the acclimation process of elephant grass cv Taiwan mutants is a combination of sand and soil media (1:1). The results of the evaluation stage of T4 mutant production are the best mutants based on morphological performance and production of plant biomass. Proximate analysis of selected plants shows that plants with mutant T2PT7 species have the best nutritional value, with nutritional content of PK 11.71% and SK 24.67%. Keywords : acclimatization, Elephant grass cv Taiwan, proximate analysis

By-products such as oil palm empty fruit bunches (EFB), palm kernel cake, and sawdust can be used as alternative feed. It contains nutrients needed by ruminants but is constrained by its high crude fiber content, including lignin, cellulose, and hemicellulose, and is low in protein. This study was conducted to evaluate the physical characteristics of the fermented media from plantation by-products using Pleurotus ostreotus as an alternative to ruminant animal feed. The experimental design was a completely randomized (CRD) with 3'3 factorial patterns with three replications. Factor A was the type of substrate, namely palm kernel cake, EFB, and acacia sawdust. Factor B was the length of fermentation, namely 0, 30, and 60 d. The data collected were analyzed by variance (ANOVA), and the results were significantly different. The observed variables were the mycelium growth rate, media weight, dry matter, organic matter, particle size, specific gravity, pile density, and compacted pile density. We conclude that the fermented sawdust gave the best growth speed of the P. ostreotus mycelia. The palm kernel cake substrate without storage showed good physical quality concerning particle size, pile density, and pile-compaction density. P. ostreotus fungus grew effectively and did not negatively impact the substrates' biomass, dry matter, and organic matter. Different substrate types give different physical characteristics to the P. ostreotus-fermented media. Keywords: acacia, empty fruit bunches, palm kernel cake, fermented media, Pleurotus ostreotus

Leucaena leucocephala is a legume forage plant that has a high protein content. Tissue culture is a technique that can be used to select mutants for forage plants in vitro. IBA (Indole butyric acid) is one type of auxin that can induce rooting and growth in plants. This study aimed to select the morphological characteristics of the acid-tolerant Leucaena leucocephala mutant to the addition of the hormone IBA in tissue culture. The design used in this study was a completely randomized design (CRD) with lamtoro plant explants as many as 11 acid-tolerant mutant lines pH 3.4 resulting from 400 gy irradiation which had been treated on 300 ppm Al3+ acid media, namely the K1-K11 strain (mutant+MS+1ppm IBA) and 2 parent trees Leucaena leucocephala without gamma irradiation, namely P0 as Leucaena leucocephala parent+MS+0ppm IBA, P1 as Leucaena leucocephala parent + MS + 1 ppm IBA with 15 replicates. The treatment which had a significant effect was continued with the test Tukey. Variables observed were an increase in root length, plant vertical height, number of shoots, and percentage of rooted plants. The increase in root length and increase in plant vertical height showed the best results on the K10 mutant strain, the number of shoots showed the best results on the K9 and K11 mutant strains, and the highest percentage of rooted plants on the K3 and K11 mutant strains. The addition of IBA can increase the morphological characteristics of the Leucaena leucocephala mutant.

Plantation by-products can be used as livestock feed with proper processing, optimizing the feed efficiency of palm kernel cake (PKC), empty oil palm bunch (EOPB), and acacia sawdust (AS). This study aimed to improve the usability of the byproducts as alternative feed through the Pleurotus ostreatus fermentation process. To this end, a 3×3 factorial, completely randomized design was applied. Factor A was the type of substrate, P1 = PKC, P2 = EOFB and P3 = AS. Factor B was the fermentation period, T1 = 0 d, T2 = 30 d and T3 = 60 d. The collected data were analyzed using analysis of variance (ANOVA), and the significantly different result was further tested using Duncan Test. The observed variables include Neutral Detergent Fiber (NDF), acid detergent fiber (ADF), hemicellulose, pH value, dry matter digestibility (DMD), organic matter digestibility (OMD), N-NH 3 , and volatile fatty acids (VFA). The study result showed that P.ostreatus mushroom in various substrate types did not significantly affect the fiber fraction of NDF, ADF, and Hemicellulose. This study also found that the interaction of substrate type and fermentation duration significantly affects dry matter digestibility, organic matter digestibility, N-NH 3 production, and VFA values. This study concluded P. ostreotus increased the nutritional value and digestibility of the by- product from plantation processing. The best fermentation duration was 60 d PKC was found to have the highest digestibility value, and the best interaction was found in PKC with 60 d of fermentation.

Sorghum is a potential crop as feed forage. The objective of the research was to obtain optimum dose of liming to improve the growth and productivity of sorghum (Sorghum bicolor (L.) Moench) biomass as feed forage. A completely randomized design with 4 treatments and 4 replications were applied for the research. The treatments were doses of dolomite lime addition i.e., 1) SD0 (dolomite lime addition at a dose of 0 ton/ha) as a control, 2) SD1 (dolomite lime addition at a dose of 1 ton/ha), 3) SD2 (dolomite lime addition at a dose of 2 ton/ha), and 4) SD3 (dolomite lime addition at a dose of 3 ton/ha). The result shows that supplementation of dolomite lime at doses of 2‒3 tons ha-1 can increase soil pH after a week of incubation. The dolomite lime addition at a dose of 3 tons ha-1 significantly increases (P<0.05) the plant height (2 weeks after planting) and the number of leaves from a week after planting until the end of the research (10 weeks after planting). In addition, this dose of dolomite addition (3 tons/ha) can increase fresh biomass productivity as well as dry biomass compared to control (SD0). In conclusion, supplementation of dolomite lime at a dose of 3 tons ha-1 was effective to increase the pH value of soil, plant height, leaves number, as well as fresh and dry biomass of sorghum plant. In addition, this dose of dolomite lime produces better green color of sorghum plant leaf compared to without liming. Keywords: biomass production, dolomite lime, feed forage, Sorghum bicolor (L.)

Arbuscular mycorrhizal fungi (AMF) are potential biofertilizers for plants. The succeed and quality of AMF inoculation is related to the type of AMF and plants. This study aimed to find the most effective AMF species in Indigofera zollingeriana nurseries. This experiment study was designed using a completely randomized design with six treatments and five replications based on different types of AMF in single and consortium forms. Treatment details include: IFMIX (consortium: a mixture of five types of AMF), IFTE (Glomus etinucatum), IFTM (Glomus manihotis), IFTA (Acaulospora tuberculata), IFTG (Gigaspora margarita), IFTS Glomus sp. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's Multiple Range Test. Based on the results of variance, AMF inoculation at Indigofera zollingeriana nurseries in a single form (IFTE, IFTM, IFTA, IFTG, and IFTS) resulted in effectiveness that was not significantly different with the consortium FMA inoculation (IFMIX) against AMF colonization, plant height, stem diameter, fresh and dry biomass of plants. Inoculation of inoculums in a single IFTE form resulted in a higher colonization value (p<0.05) than single inoculums IFTA and IFTM. It can be concluded that inoculation of a single AMF (Glomus etinucatum, Glomus manihotis, Acaulospora tuberculata, Gigaspora margarita, Glomus sp.) against AMF consortium produced the same symbiotic effectiveness on root colonization, morphological response and plant biomass production level in Indigofera zollingeriana nurseries. The root colonization rate of a single IFTE inoculum was better than a single inoculum of IFTA and IFTM. Key words: consortium AMF, Indigofera zollingeriana nurseries, single AMF
