Abstract

An analysis of the roles of stakeholders was conducted as a continuity program of Peternakan Sapi Terpadu (PESAT; integrated beef cattle farm) following the coal mining deactivation by PT Kaltim Prima Coal (KPC) of East Kutai, East Kalimantan. The purpose of this study was to formulate stakeholders relation in the future program. The stakeholders involved in this program were PT KPC, local breeders, Sekolah Tinggi Ilmu Pertanian (STIPER; Agriculture Academy) of East Kutai, and the local government of East Kutai. The stakeholders analysis was based on the variables of the importance and influence from every analyzed stakeholder. The analysis model used here was the model introduced by Reed et al. (2009). According to the result of the stakeholders analysis, PT KPC was in the key-player quadrant, which score is 25 in both of the interest and the influencial level,  while the three others, such as, local breeders, STIPER of East Kutai, and the East Kutai Government were in the subject quadrant. Their score were 24 and 7 for Local breeders, 21 and 9 for STIPER of East Kutai, and 16 and 13 for The East Kutai Government.  It means, they had high interest but low influence to the program. The conclusion of this analysis shows that PT KPC is still dominating in the PESAT program management, whereas the three other stakeholders are acting merely as program users that have low involvement in the program management.

Abstract

The experiment was conducted to investigate the adaptive grasses growing under shading albizia, rubber and oil palm canopy. Three species of tropical grasses (Brachiaria humidicola (Rend.) Sch., Digitaria decumbens Stent, dan Stenotaphrum secundatum (Walter) O.Kunt. were cultivated for at least four months. The parameters of research were productivity (including tillering rate) and nutrient quality of each grass. Data were analyzed using Split-plot design and for the significant differences were further tested by Least Significant Different (LSD). The result showed that B. humidicola production was better than other species in plantation and forest shaded. This species producting higher fresh yield and crude protein, but its tillering rate was poor. S. secundatum, although its production was not as great as B. humidicola, this grass had the greatest tillering rates compared to the others. It can be recommended that S. secundatum is persistent species, and has a good productivity for a long periode of time under shading. Key words: tropical grasses, shading, tillering rates, persistent

Abstract

An investigation on growth behavior parameters and its dynamic pattern of signal grass (Brachiaria humidicola) grown under influence of inorganic and organic nutrient supply was conducted during period of wet and early dry seasons in 2004. Five sets of treatments consisted of control (P0), mulch originated from pasture weed biomass (Chromolaena odorata) (PC), animal dung (PF), combination of mulch and dung (PC+F) and inorganic fertilizer (PA) were applied to one year existing signalgrass plots. Block randomized design with 4 replications was used in this experiment. The results showed that application of PA produced the highest length of stolons, node and tiller numbers. There was an improvement of growth by application of PC, PF and PC+F, but at lower level than those of PA. Application of PA caused short growth period (6-8 weeks) to reach maximum length of stolon, node and tiller numbers, but less persistent (10-12 weeks) if the grass had not been defoliated. On the other hand, application of organic nutrient led to slow growing grass, but it showed more persistent. The application of organic nutrient supply (PC, PF and PC+F) resulted the best growth of signal grass in comparison with control and more persistent than that of inorganic fertilizer (PA). Key words: Brachiaria humidicola, stolon, tiller, node, mulch

Abstract

An excellent animal performance has to be supported by feed availability. Quality and quantity of forages are important factors. The existence of weeds significantly decreases rate of production and quality of herbage. Physically weed control by defoliation could be expected to sustain quality and production of herbage, and able to control weeds expansion. The aims of the study were to find the effect of interval defoliation of B. humidicola that was invaded by C. odorata and its effect on production, crude protein, phosphor, calcium contents of B. humidicola herbage, production and population dynamic of C. odorata. The treatments were nine different planting methods and different defoliation intervals, namely: B. humidicola was defoliated every 30 days without C. odorata (P1); B. humidicola was defoliated every 60 days without C. odorata (P2); B. humidicola was defoliated every 90 days without C. odorata (P3); B. humidicola were defoliated every 30 days, C. odorata were not defoliated (P4); B. humidicola were defoliated every 60 days, C. odorata were not defoliated (P5); B. humidicola were defoliated every 30 days, C. odorata were not defoliated (P6); B. humidicola and C. odorata were defoliated every 30 days (P7); B. humidicola and C. odorata, were defoliated every 60 days (P8); B. humidicola and C. odorata were defoliated every 90 days (P9). Two experiment designs namely Completely Randomized Block Design and Split Plot Design in Time were used in the field experiments. The result of the experiments showed that dry matter production of B. humidicola which were defoliated every 90 days were not significantly different than those defoliated every 60 days, but it was significantly higher than those defoliated every 30 days. Crude protein, phosphor, and calcium content of herbage which were defoliated every 30 days were significantly higher than those defoliated every 60 days and 90 days. Present and defoliation of C. odorata did not affect the herbage production, and phosphor content, but it decreased crude protein and calcium content of B. humidicola herbage. Keywords: production, quality, herbage, defoliation interval

Abstract

Corn is used as foodstuff and industrially utilized feed as a potential ingredient in animal ration. Green forage, baby corn and its cobs are used also as ruminants feed. Application of Chromolaena odorata on latosol as mulch material is expected to improve corn production by contributing organic nutrition. The objectives of this research were to recognize the effect of Chromolaena odorata on production and quality of green forage of high density corn, and to observe the contribution of phosphorous mineral from decomposition of Chromolaena odorata in the ground. This research was divided into two steps of experiment. The first experiment, consisted of two levels of treatments, i.e.: with and without Chromolaena odorata (12 ton/ha). The plants were fertilized with 60 kg K/ha and 225 kg N/ha. Plant was harvested at 40 days after planting. In the second experiment, corns were cultivated in the same area and the application of mulch (12 ton/ha) and P (60 kg/ha). Mulch increased significantly vertical height but there was no effect on production of green forage, mineral content in crop and uptake of P and N. In the second experiment, mulch addition improved vertical height of the crop, fresh and dry weight of green forage, content of P and N on the tissues of crop and also uptake of P and N between two treatments were not significant. Application of Chromolaena odorata mulch (2x12 ton/ha) was similar as the addition of P anorganic (60 kg/ha) in improving growth, production and quality of green forage of corn. In this research, the mulch improved the content of mineral P and N in the soil. Key words: mulch, Chromolaena odorata, mineral P, corn

Abstract

The objective of this experiment was to evaluate the effect of drought stress and mycorrhizal inoculation on physiological adaptation and biomass production of Macroptilium bracteatum. This experiment was arranged in completely randomized design with four treatments: M0 (no AM + watered), M1 (AM + watered), M2 (no AM + drought), and M3 (AM + drought) with three replicates. The observed variables were soil water content, leaf water potential, leaf relative water content, leaf proline, leaf water soluble carbohydrate (WSC), root and shoot dry weight. Data were analyzed by ANOVA and differences between treatments were tested by DMRT. Drought treatments (M2 and M3) significantly (P < 0.05) decrease soil water content, leaf water potential, leaf relative water content and increased the leaf proline content. The result in root and shoot dry weight appear that M1 treatment was significantly different (P < 0.05) with treatment M0, M2, and M3. For leaf WSC, M0 and M2 treatments were significantly different (P < 0.05) with treatment M1 and M3. It is concluded that mycorrhiza inoculation was more effective on M. bracteatum, in drought stress. One mechanism of drought resistance of M. bracteatum is the accumulation of osmotic compounds proline. Therefore, proline can be used as an indicator of drought resistance in leguminous plants.

Abstract

One of the main constraints in increasing livestock productivity in the tropical region is the scarcity of good quality feed throught the year, particularly during the long-dry season. Being a leguminous tree, Indigofera sp known to be tolerant to dry climate and salinity, should be considered as alternative fodder for ruminant animals. This study is aimed to investigate the productivity and some nutritional quality of Indigofera sp under different interval and hight of defoliation. The experiment was designed in a randomized block of factorial treatments. The factors were interval of defoliation (30, 60 and 90 days) and hight of defoliation (0.5, 1.0 and 1.5 m above ground level). Indigofera sp was planted in 4 x 3 m plots of 36 plots (4 replications) and were harvested at 8 months old. The DM production, chemical composition and in vitro digestibility were measured according to the treatments. The highest DM productivity was (33.25 t ha-1 y-1) at defoliation interval of 90 days and defoliation hight of 1.5 m, and was not different (P > 0.05) from the treatment combination of 60 days defoliation interval and 1,5 m defoliation hight (31.23 t ha-1 y-1). The highest leaf/stem ratio was 2.6 (P < 0.05) in the 30 day defoliation interval across the defoliation hight. The OM content of Indigofera sp was not affected by defoliation treatments and ranging from 884.6 to 906.8 g/kg. The highest NDF and ADF contents were (P < 0.05) in the 90-d defoliation interval and 1.0 m (387.9 and 272.6 g/kg, respectively) and were not different (P > 0.05) for the 90-d defoliation interval and 1.5 m defoliation hight (385.6 and 267.0 g/kg, respectively). The crude protein content was lowest (P < 0.05) in the 30-d defoliation interval across the defoliation hight ranging from 211.2 to 219.7 g/kg, and it was not different between the 60 and 90-d defoliation interval across the defoliation hight (255.0-258.1 g/kg and 230.3-236.0 g/kg, respectively). Defoliation hight did not affect (P > 0.05) the DM and OM in vitro digestibility. They were at the 90-d defoliation interval ranging from 680.2 to 706.8 g/kg and from 668.6 to 686.8 g/kg, respectively across the defoliation hight different. The DM and OM digestibility were not different (P > 0.05) between the 30 and 60-day defoliation intervals. It is concluded that when planted at low land of wet climate the combination of a 60-d defoliation interval and 1.5 m defoliation hight is an optimum cutting management in utilization of Indigofera sp as foliage for ruminant.

Abstract

Kalopo (Calopogonium mucunoides) was used as cover crops in plantation. Besides, kalopo can be used as forage, esspecially in dry season. The aim of this study was to evaluate the effect of light intensity on forage and seed production. Research was conducted at Research Institute for Animal Production, Ciawi Bogor and Laboratory of Agrostology Faculty of Animal Husbandry, Bogor Agricultural University, for 16 months. Four levels of light intensity, namely: 100%, 80%,60% and 40% were applied, leguminous species of kalopo (Calopogonium mucunoides), was used. Block Randomized Design with 3 replications was applied in this research. Data collected was analyzed by ANOVA and Duncan’s Multiple Range Test. Forage production was evaluated within one year. The forage quality and digestibility (invitro) were investigated. Seed production was accumulated as seasonal seed production during one year. The results showed that light intensity affected (P < 0.05) forage and seed production, chlorophyll and total chlorophyll of kalopo, but did not affect (P > 0.05) quality and digestibility of kalopo. Seed production of kalopo was affected (P < 0.05) by light intensity, the highest forage and seed production of kalopo were obtained from treatment of full light intensity (100%). The seed quality of kalopo was affected by light intensity. The best seed quality of kalopo was achieved from 80% light intensity. The result shows that plots with light intensity of 100% was the best light intensity for forage and seed production of kalopo. Kalopo could grow well in the plots up to 80% light intensity. Key Words: Light Intensity, Forage, Seed, Kalopo

Abstract

Local buffalo rumen fluid is a source of fiber digesting bacteria. Such bacteria presumably are well adapted to feed stuffs derived from agricultural byproducts with low quality. The purposes of this study were: (1) to isolate the fiber-digesting bacteria from buffalo rumen fluid, (2) to determine the fiber digesting characteristics and adaptability of such bacteria, and (3) to characterize the bacterial diversity.  Rumen fluids for the experiment were collected from buffaloes slaughtered at the Faculty of Animal Science, Bogor Agricultural University abattoir. Fiber-digesting bacteria were isolated using McDougall buffer supplemented with fibrous feed. A factorial experiment was conducted to study characteristics and adaptability of the bacteria using two factors: the type of bacteria and type of feed source of the fiber. Diversity among the bacteria was analyzed using the NTSys2.10 program.Results showed that nine bacterial isolates had a high adaptability to fiber feed based on CMCase. The highest CMCase activity bacteria for Pennisetum purpureum were A9 (11.36±1.70 unit/ml/h), A3 (11.22±0.60 unit/ml/h) and A42 (10.62±1.96 unit/ml/h). CMCase activity of fiber digesting bacteria from buffalo rumen fluid was not correlated with the number of bacteria in the culture. Based on genetic similarity, nine isolates were grouped into five types having similarity≥46%. Key Words: Buffalo Rumen Fluid, Fiber-Digesting Bacteria, Low Quality Forage

Abstract

The objectives of this experiment was to evaluate the effect of drought stress and defoliation interval on shoot and root morphologic characteristic of Indigofera zollingeriana. The experiment was arranged in a completely randomized design with two factors and four replications. The first factor consisted of 3 level of drought stress i.e: 100% field capacity (FC) (control), 50% FC, and 25% FC. The second factor comprised of 3 defoliation interval were interval defoliations of 60, 90 and 120 days. The observed variables were shoot, root dry weight, root/shoot ratio and root length. Data were analyzed by ANOVA and the differences between treatments were tested by LSD. The results shows that there were interactions (P < 0,05) between drought stress and defoliations interval on shoot dry weight, while root dry weight, root/shoot ratio, and root length was not. Drought treatment significantly (P < 0,05) decreased shoot, root dry weight, but increase of root/shoot ratio and root length. Defoliation interval significantly affected (P < 0,05) on shoot dry weight, but not on root dry weight, root/shoot ratio, and root length. Key Words: Indigofera zollingeriana, Drought Stress, Defoliation Interval, Shoot And Root Morphology
