PRODUKSI DAN KANDUNGAN NUTRIEN HIJAUAN RUMPUT Pennisetum purpureum cv Mott, DENGAN PEMBERIAN PUPUK ORGANIK CAIR HASIL VERMICOMPOSTING LIMBAH SAPI POTONG

Fertilization is a very important effort for Dwarf Elephant Grass (Pennisetum purpureum cv Mott) to achieve forage production and high nutritional quality following its potential. This research aims to determine the yield of dry matter, crude protein content, and crude fiber of Dwarf Elephant Grass by application of liquid organic fertilizer (LOF) resulting from vermicomposting of beef cattle waste. The research was conducted at the Field Laboratory of Forage Crop, and the Ruminant Animal Nutrition and Feed Chemistry Laboratory, Faculty of Animal Husbandry, Padjadjaran University from January to June 2018. The research method used was the experimental method with a Completely Randomized Design using 3 treatments, namely P1 (5,000 L per Ha), P2 (10,000 L per Ha), and P3 (15,000 L per Ha), and 6 replications. Data were processed by analysis of variance and continued with Duncan's Multiple Range Test. The results showed that giving LOF increased the production, increased the content of crude protein, and decreased the crude fiber content of Dwarf Elephant Grass forage. Giving LOF from vermicomposting beef cattle waste at a dose of 15,000 L per Ha resulted in the highest forage dry matter yield (1,925 kg per Ha), one-time cutting at dry season, and the best nutrient content seen from the crude protein content (13.95%) and crude fiber content (28.53%).

Does the presence of tall or dwarf elephant grass genotypes change the nutritive value of butterfly pea in grass–legume intercrops?

Adding tropical legumes into grass-based forage systems may increase the nutritive fodder value, but competition may decrease legume quality. We evaluated the nutritional values and agronomic responses of tall and dwarf elephant grass genotypes (Cenchrus purpureus (Schumach.) Morrone.) and butterfly pea (Clitoria ternatea L.) grown as binary intercrops. Two tall (Elephant B and IRI-381) and two dwarf elephant grass genotypes (Mott and Taiwan A-146 2.37) were the grass components of intercrops in a two-year trial. Higher acid detergent fibre (ADF) and lignin contents were found in tall than dwarf elephant grass genotypes (p < 0.0001), while lower coefficients of in vitro digestible dry matter (IVDDM) were recorded in tall than dwarf elephant grass genotypes (p < 0.0001). There was no intercrop effect on the herbage accumulation (p = 0.1278), dry matter (DM) contents (p = 0.2338), neutral detergent fibre (NDF) (p = 0.2022), lignin (p = 0.7179) and condensed tannins (p = 0.1699) of the butterfly pea. The butterfly pea grown with tall genotypes had higher crude protein (CP) concentrations (p = 0.0001) and coefficients of IVDDM (p = 0.0086) than when intercropped with dwarf genotypes. The study showed that tall elephant grass genotypes improved the butterfly pea’s nutritional value in grass–legume intercrops through increases in leaf/pod ratio. Intercropping with butterfly pea may compensate for the lower nutritive fodder value of tall elephant grasses compared to dwarf genotypes.

Potential use of coal ash as growing media: Effect on the plant’s growth and future estimation for land reclamation

Coal ash, such as fly ash (FA) and bottom ash (BA) is mostly generated from a Coal-fired Steam Power Generation (PLTU) process. An increase in the number of PLTUs in Indonesia is proportional to the high volume of FA and BA generated, causing adverse environmental impacts if not properly treated. Various studies have highlighted the potential valorization of FA and BA, including building materials, cement ingredients, concrete, and growing media. This study aimed to evaluate the potential use of FA and BA as a growing media and to explore the potential future application for reclamation of heavy-metal-contaminated (or ex-mining) land. The results showed that composting FA with blackwater sludge (BWS) and rice straw (RS) produced compost that complied with the targeted standard. The addition of FA, BA, and composted FA in the growing media impact the growth and Zn adsorption ability of the dwarf elephant grass (Pennisetum purpureum cv. Mott). However, the composted FA has superior performance in general as a growing media. The future estimation of the application FA and BA combined with domestic waste (blackwater and greywater) for reclamation of ex-mining land is proposed. By integrating the phytoremediation ability of the grass plants and the biorefinery approach, the proposed future estimation may provide a sustainable valorization pathway of FA and BA for heavy metal-contaminated or ex-mining land reclamation. Thus, transforming FA and BA as a component of growing media could reduce the potential risk of heavy metals distribution into the food chain and the surrounding environment.

Efektivitas Penggunaan Pellet Berbasis Rumput Odot Dan Kombinasinya Terhadap Performans Kelinci Rex Jantan

Abstract This study aims to determine the effectiveness of using Dwarf Elephant Grass -based pellets and the combination on the performance of male Rex Rabbits. This study used 20 male Rex rabbits with an average body weight of 1222.61 ± 49.39 g/head (cv ±4,04%). The design used was a completely randomized design (CRD) with a unidirectional pattern with 4 treatments and 5 replications. The rations given were “Citra Feed” comercial pellets and Dwarf Elephant Grass -based pellets. The treatments were T0 (100% commercial pellet), T1 (70% commercial pellet + 30% Dwarf Elephant Grass pellet), T2 (30% commercial pellet + 70% Odot pellet), T3 (100% Dwarf Elephant Grass pellet). The results of statistical analysis showed that using Dwarf Elephant Grass -based pellets had a very significant effect on dry matter (P&lt;0.01), and had a significant effect on ADG and feed cost per gain (P&lt;0.05), not sicnificantly different to feed convetion ratio (P&gt;0,05). From the results of the study, it was concluded that using Dwarf Elephant Grass based pellets as much as 30% of the total ration increased the performance of male Rex Rabbits.

Proportion of Sawdust as Carbon Sources in Rabbit Manure Compost for Increasing the Growth of Pennisetum purpureum cv Mott

The right proportion of carbon in high N organic matter source in composting process will result good decomposition process. In this study, rabbit manure was composted with different portion of sawdust, and then the chemical properties were evaluated. The compost then applied to determine the growth response of dwarf elephant grass (Pennisetum purpureum cv. Mott) in terms of plant height, number of leaves, root and shoot dry matter, shoot and shoot ratio, and N content in shoot. The results showed that compost consisted of rabbit manure + sawdust with the ratio of 3:1 and 1:1 had good chemical properties (pH around 7.56 - 7.94, C/N ratio 17 – 19, C- organic 19 – 24%, Nitrogen 0.84 – 1.31%, Phosphor 0.43 – 0.82%, and Potassium 0.27– 0.37%) as well as sole rabbit manure compost. Applying compost to Mott grass resulted a good growth response which reflected in plant height (78.29 - 83.46 cm/plant), leaves number (53.50 - 57.92 blades), shoot dry matter (39.69 – 54.56 g DM/plant), root dry matter (16.50 – 18.16 g DM/plant), shoot : root ratios (2.52 - 3.20), and shoot N content (37.14 - 48.55 g DM/plant). The study concluded that compost rabbit manure + sawdust with ratio of 3:1 resulted the same growth response with sole rabbit manure compost.

&#x0D; &#x0D; &#x0D; The purpose of this study was to identify body dimensions that influenced the growth of goats reared in Bugis Village, Serangan Village, Denpasar, Bali. Data were obtained through direct observations, formal goat farmer in- terviews and key informant interviews that were conducted from April to July 2018. Two of the remaining three farmers who still kept rearing goats in Serangan Village were involved in this study. Each farmer housed his goats with a colony housing system and fed forages 10% of total body weight/day (control). One farmer supplemented ad- ditional feed of dwarf elephant grass (Pennisetum purpureum cv. Mott) silage (treatment). The variables observed: body weights, chest circumferences, body lengths, height of withers, and rump heights. This result showed that the body weight of 8 control goats was 30.67 ± 239 kg, which was significantly heavier than those of 29 treatment goats 20.65 ± 1.28 kg (P&lt;0,05), however body weight of the treatment goats aged &gt;5 years 38.73 ± 1.09 kg was significan- tly heavier than 33.33 ± 209 kg of those of the control goats (P&lt;0.05). The highest correlation value in this result showed R2=0.964 between body weight and body length.&#x0D; &#x0D; &#x0D;

Dwarf and Tall Elephantgrass Genotypes under Irrigation as Forage Sources for Ruminants: Herbage Accumulation and Nutritive Value.

Simple SummaryCyclical droughts negatively impact agriculture, with deficits of water availability for the maintenance of crops destined for human food and animal production. Seasonality of forage quantity and quality is a critical obstacle to support domesticated herds over the year. Elephantgrass (Pennisetum purpureum Schum.) is a tropical forage widely used for feeding ruminants, mainly in the form of cut-and-carry, which has the potential to increase tropical pasture productivity, due to the large amount of roughage produced per unit of area. Research evaluated the response of tall and dwarf elephantgrass genotypes under irrigation considering its potential for complementing ruminant diets. This study showed that irrigation of elephantgrass, particularly during the dry season, may improve the regularity of forage production with good nutritive value.This two-year study evaluated the effect of Pennisetum purpureum genotypes under rainfed or irrigated conditions, during the dry and rainy seasons, on herbage, leaf, and stem dry matter (DM) accumulation rates, nutritive value, and carbohydrate and protein fractionation. Treatments were tall (Iri 381 and Elefante B) or dwarf (Mott and Taiwan A-146 2.37) genotypes under rainfed or irrigated conditions. Taiwan A-146 2.37 (146 kg DM ha per day) showed similar herbage accumulation rate (HAR) to tall genotypes during the rainy season (124 and 150 kg DM/ha per day, respectively). Dwarf genotypes showed differences in leaf accumulation rate (LAR) (66 and 49 kg DM/ha per day). Mott leaf had less neutral detergent fiber (NDF) (589 g/kg DM) than Taiwan A-146 2.37 (598 g/kg DM), and tall genotypes had generally greater NDF (668 g/kg DM) than the dwarf genotypes. Irrigation increased fiber deposition in the leaf. Stems of all genotypes had lower in vitro digestible dry matter (IVDDM) (378 g/kg DM) under rainfed conditions in the rainy season. Leaf from irrigated plots had 23% more carbohydrate C fraction (160 g/kg CHO) than those from rainfed plots (122 g/kg CHO). Dwarf genotypes had generally greater nutritive value than tall genotypes. These genotypes show promise under irrigation to fill forage gaps during dry periods.

This research aimed to determine the effect of bokashi dose on crude protein and crude fiber content at the first cut of dwarf elephant grass (Pennisetum Purpureum cv. Mott). This research was conducted in March—Juli 2020 in Sidodadi Asri village, Jati Agung district, South Lampung regency. This research used a completely randomized design (CRD) applying four treatments of bokashi dose, namely P0 (control), P1 (30 ton/Ha); P2 (40 ton/Ha); dan P3 (50 ton/Ha) with 3 replications each. The experimental unit of this study was plot of land with size of 200 cm x 200 cm. The obtained data were then analyzed using analysis of variance at 5% significant level and tested further with Orthogonal polynomial. The results showed that there was no significant effect (P&gt;0.05) of different dose of bokashi on the crude protein and crude fiber content of dwarf elephant grass.&#x0D; &#x0D; Keywords: : Dwarf Elephant Grass, Dose, Bokashi,Crude Protein, Crude Fiber

PENGARUH DOSIS BOKASHI TERHADAP PERTUMBUHAN DAN PRODUKSI PADA PEMOTONGAN PERTAMA RUMPUT GAJAH MINI (Pennisetum Purpureum cv. Mott)

This research aims was to determine the effect of bokashi dose on plant height, number of tillers, percentage of stems, fresh production, and dry matter production and also to determine the optimum dose of bokashi to obtain the best results on growth and production at the first harvest of dwarf elephant grass. This research was conducted in March 2020 - July 2020 in Sidodadi Asri village, Jati Agung district, South Lampung regency. This research used a Completely Randomized Design (CRD) with 4 levels of treatment, namely P0 (control); P1 (bokashi dosage 30 tons/ha); P2 (bokashi dosage 40 tons/ha); and P3 (bokashi dosage 50 tons/ha). Each experimental treatment unit has plot measuring 2x2 m2. Each trial unit was repeated 3 times, so there were 12 trial units. The data were analyzed by variations analyzed at 5% and or 1% level, after that it was followed by orthogonal polynomial test. The results showed that the dose of bokashi had a significant effect (P&lt;0,05) on plant height, fresh production, and dry production, but had no significant effect (P&gt;0,05) on number of tillers, and percentage of stems. The effect of bokashi fertilizer on plant height was obtained by using the optimum bokashi dose of 36.73 tons/ha and the equation was = 60,13 + 35,38x - 6.62x2 [0 ; 50 ton/Ha] (P&lt;0,01). The optimum dose was not obtained for the number of tillers, percentage of stems, fresh production, and dry production.&#x0D; &#x0D; Keywords: Plant height, Number of tillers, Percentage of stems, Fresh production, Dry production

Effect of harvesting age of chicory (Cichorium intybus) on the pattern of planting intercropping dwarf elephant grass in the second regrowth on production and quality

The research was conducted to evaluate the effects of harvesting age in the second regrowth of chicory (Cichorium intybus) in intercropping pattern with dwarf elephant grass (Pennisetum purpureum cv. Mott) on productivity and quality. Chicory seeds were spread on the interspatial land between the dwarf elephant grass on a 2.5×2.5 m2 plot, with 1×1 m2 of the distance between each dwarf elephant grass. Plants were harvested on the day- 30, 45 and 60 by defoliation 10 cm above the soil surface. Each treatment had 3 replications, totaling 9 plots. The variable measured in the study were production (dry and organic matter) and nutrient contents (dry matter, organic matter, extract ether, and crude fiber). Data were analyzed using a one-way analysis of variance. Significant data were evaluated on Duncan’s New Multiple Range Test (DMRT). The results of the study showed that plants that were cut later had the highest production and nutrient contents (P<0.05). Groups harvested at later cutting ages had higher dry matter production (chicory and dwarf elephant grass). However, chicory and dwarf elephant grass on older harvesting also had higher crude fiber (13.07% and 26.87%). Crops harvested at 60 days in the second regrowth demonstrated the most improved yield.

The Effect of Harvest Age on Different Regrowth on Chicory (Cichorium intybus L.) Forage Yield by Intercropped with Pennisetum purpureum cv. Mott

This research was carried out to examine the chicory forage yields on different regrowth which were intercropped with Pennisetum purpureum cv. Mott (dwarf elephant grass) on different regrowth due to various harvest age. The research was conducted in the Laboratory of Forage and Pasture, Faculty of Animal Science UGM for 7 months, with a split-plot design and analyzed by Duncan with a total of 9 plots and an area of 2.5x2.5 m2 for each plot. The main plot was the harvest age treatment (30, 45, and 60 days) and the subplot was the regrowth (first and second). In the first stage, as many as 9 cuttings of dwarf elephant grass in one plot were planted with a spacing of 1x1 m2 until the plant height reaches 10 to 15 cm, then the chicory seeds were spread among the dwarf elephant grass plants with the sand mixture. The results showed the harvest age had a significant effect (P&lt;0.05) on chicory's plant height, fresh forage yield, dry matter content, dry matter digestibility, and organic matter digestibility. The 30 to 45 days harvest age performed a higher fresh production more than the 45 days to 60 days harvest age. The 60 days harvest age and second regrowth yielded the highest mixed fresh production compared to the other harvest ages, namely from 12.50 ton/ha to 25.26 ton/ha. Based on the research results showed that the older the harvest age (60 days) increased the biomass of plant production but decreased the plant digestibility. The second regrowth was able to produce higher than the first regrowth, but there was no significant effect on the dry matter content and forage digestibility.

Dwarf versus tall elephant grass in sheep feed: which one is the most recommended for cut-and-carry?

Tall- and dwarf-sized elephant grass cultivars have been developed for cut-and-carry system. Dwarf clones have better digestibility; on the other hand, tall-sized cultivars are more productive. The aim was to verify which grass would be most recommended for cut-and-carry: tall-sized (Elephant B and IRI-381) or dwarf (Taiwan A-146 2.37 and Mott) elephant grass cultivars to feed 24 male sheep, aged between 4 and 5months, uncastrated, weighing approximately 24.08 ± 1.76kg body weight which were sampled on intake, digestibility, performance, ingestive behavior, nitrogen balance, microbial protein synthesis, metabolic parameters, and ruminal degradability. This research was divided into two experiments: experiment 1 lasted 38days, seven for adaptation and 31 for data collection. Elephant grass cultivars were supplied with a mineral mixture. Data collected were intake, digestibility, ingestive behavior, metabolic parameters, microbial protein synthesis, and performance submitted to a completely randomized design. For experiment 2, three rumen fistulae animals were sampled, lasting 20days. In this case, a randomized block in split-plot design was applied. Both designs were with P < 0.05 and analyzed through SAS statistical software. Mott and Taiwan A-146 2.37 cultivars provided greater intake, digestibility, weight gain, feeding time, nitrogen retention, production and efficiency of microbial protein synthesis, dry matter (DM) and neutral detergent fiber (NDF) degradability, and DM, crude protein, and NDF, but shorter rumination time rather than Elephant B and IRI-381. There was also a significant difference for glucose, triglycerides, plasma urea, total serum protein, urinary urea (mg/L), and urea excretion in urine (mg/day). Dwarf elephant grass cultivars as Mott and Taiwan A-146 2.37 have greater nutritional value than tall-sized Elephant B and IRI-381. Dwarf elephant grass is recommended for cut-and-carry system.

Grass size and butterfly pea inclusion modify the nutritional value of elephant grass silage

Abstract: The objective of this work was to evaluate the nutritional value of silages from tall-sized and dwarf elephant grass (Pennisetum purpureum) genotypes, intercropped or not with butterfly pea (Clitoria ternatea). The experiment was performed in randomized complete blocks, in a 4x2 factorial arrangement (four genotypes × two cropping systems). The genotypes intercropped or not with butterfly pea were: IRI-381 and Elephant B, tall sized; and Taiwan A-146 2.37 and Mott, dwarf. Forage was harvested 60 days after regrowth. In the silage from Mott grass intercropped with butterfly pea, lower contents of lignin (78.1 g kg-1), neutral detergent fiber (636.0 g kg-1), and neutral detergent insoluble protein (13.15 g kg-1), besides a greater dry matter recovery (873.3 g kg-1), were observed. The silage from Taiwan A-146 2.37 intercropped with the legume showed a greater crude protein content (136.1 g kg-1). In both silages, the ammonia nitrogen contents were quite reduced (26.4 g kg-1). However, greater residual water-soluble carbohydrate contents were observed in the silages from the intercrop (1.85 mg g-1) and from the Mott grass monocrop (1.51 mg g-1). Moreover, there was a lower in vitro dry matter digestibility (676.7 g kg-1) for the silage from the intercrop. Dwarf genotypes increase the nutritional value of elephant grass silage, compared with the tall-sized ones. Intercropping with butterfly pea improves silage fermentation characteristics, despite reducing its digestibility. Therefore, the ensilage of dwarf Mott elephant grass intercropped with butterfly pea shows more promising results.

Synchronization Protein-Energy Index of Various Forages for Dairy Livestock: an In Vitro Study

The present study inventoried the protein-energy synchronization (PES) index of various types of grass. The study was conducted using in vitro techniques with material 5 types of grass (elephant, king, dwarf elephant, guinea, and setaria) and rumen fluid of the Friesian Holstein (FH). The PES index is calculated based on the average degradation of g protein and Kg organic matter (OM) per hour at the time of observation of 2nd, 4th, 6th, 8th, 12th, 24th, 48th, and 72nd hours. The hourly degradation rates were analyzed by linear regression to obtain the average hourly degradation rate. The results were included in the PES index calculation formula and discussed descriptively. This study found that all five grass had almost uniform nutritional value. Regression analysis results show a different equation, but with a high coefficient of determination (&gt; 90%) on all types of grass. The PES index obtained in elephant, king, dwarf elephant, guinea, and setaria grass are 0.72, 0.66, 0.69, 0.58, and 0.68. The study concluded that elephant grass has a PES index at a high level, while king, dwarf elephant, guinea, and setaria grass at medium level for compiling dairy rations.

This research aimed to examine the effect of different Lactobacillus plantarum addition and fermentation periods on its physical quality, pH, nutritive value ( dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), extract ether (EE)). This research also to find out the best treatments of dwarf elephant grass silage by Lactobacillus plantarum addition with different fermentation periods. Completely Randomized Factorial Design was used in this experiment, with two factor ie. Lactobacillus plantarum inclusion (0, 0.3; 0.6; 0.9 %) and fermentation periods (0, 7, 14, 21 days). Each treatment was replicated three times. Addition 6 % molasses of fresh weight grass was employed in all the treatment. The result indicated that different of Lactobacillus plantarum addition, fermentation periods and their interaction were highly significant effect on pH, OM, CF and EE value (p<0.01). Interaction of two factors also highly significant influence to DM and CP content of dwarf elephant grass silage. Lactobacillus plantarum addition factor has highly significant effect on CP content and fermentation period was a significant effect on CP value of dwarf elephant grass silage. Physical quality of dwarf elephant grass with various Lactobacillus plantarum addition and fermentation periods shown a good quality of silage with fresh and acidic odor, good texture, a little bit browny color, and no fungi. Average pH of silage was around 3.90 – 4.30 after incubation 7 – 21 days. Average of nutritive value dwarf elephant grass silage were 11.55 – 13.15 % DM, 81.13-82.32 % OM, 10.48 – 12.00 % CP, 22.31 – 25.27 % CF and 1.21 – 2.98% EE. It can be concluded that Lactobacillus plantarum addition can faster ensilage fermentation and the best silage was on treatment 0.6 % Lactobacillus plantarum addition and 7 days fermentation periods.

The influence of EDTA on the accumulation, movement, and distribution of cadmium in dwarf elephant grass

Abstract This research aims to study the influence of EDTA on the accumulation and distribution of Cd in dwarf elephant grass. The research studied concentrations of Cd and EDTA at 20, 40, 60, 80, and 100 mg/L as well as mixtures of Cd and EDTA at molar ratios of 1:0.5, 1:1, and 1:2 mol. Plants were analyzed with AAS and LA-ICP-MS every 15 days over a total of 45 days. A Cd concentration of 40 mg/L was used to test the mixtures of Cd and EDTA. A 1:2 molar ratio of Cd and EDTA was found to be the most appropriate for phytoremediation. The plants showed effective growth, low phytotoxicity, and a high accumulation of Cd. The highest Cd accumulation in plants at the end of the experiment was 1,017.39 mg/plant, which accumulated in the underground parts (roots) and aboveground parts (stems and leaves) at 683.70 and 333.69 mg/plant, respectively. LA-ICP-MS analysis showed that Cd accumulation was highest in the underground parts of plants. This result was in accordance with the quantitative data from the AAS. Therefore, it can be concluded that plants mostly accumulate Cd in their underground parts, especially with added EDTA (1:2 mol at 105 days). LA-ICP-MS can be used to conclude with certainty that EDTA is an important factor for effectively inducing Cd into the root system.

The Level of Dwarf Elephant Grass (Pennisetum Purpureum cv. mott) To Substitute Indigenous Forage for Goat Feed in Limestone Mountain

This research aimed to investigaton on the level of supplementation of dwarf elephant grass that was introduced ex-limestone mining open area as to substitute indigenous forage for goat feed in limestone mountain.The method used in vivo experimental research was conducted in a completely randomized design. Sixteen local male goats in a limestone mountain weighed 24.8 kg ± 1.66 were allotted to four treatments with different level of dwarf elephant grass to subtitute indigenous forage 0, 25. 50 and 75%each with four replicates. The measured parameters were feed intake and body weight gain. The research was conducted in a limestone mountain in Gombong, Central Java Indonesia.The result showed that substituting indigenous forage with dwarf elephant grass up to 75% produced non-significantly different (P>0.05) feed intake and body weight gain of goats. The research concluded that dwarf elephant grass can to subtitute indigenous forage for goat feed, however it is recommended to substitute indigenous forage with up to 25% dwarf elephant grass to obtain an optimal weight gain to goats in limestone mountain.
