Abstract

Peatlands have specific characteristics with waterlogged conditions, fragile, and less fertile. The level of peatlands fertility dependent on depth peat and the distance from rivers. This study was aimed to evaluate nutrient adequacy and prevalence of worm infestations in the gastrointestinal tract of Bali cattle that maintained in different peatland categories. The research was conducted in Pulang Pisau District, Central Kalimantan. The site was determined by purposive sampling and divided into 3 categories peat swamp, shallow peat near the river, and shallow peat away from the river. The data were collected by survey method and laboratory analysis. The variables observed included forage quality, nutrient intake, the number of infected cows, and the number of eggs per gram of feces (EPG). The results showed that each category of peatland have different feed quality and nutrient adequacy (P<0.05). The nutrient intake in the peat swamps was relatively higher than that of other sites. In general, the nutrient adequacy of cattle raised in the peatlands area was still below the standard requirement. In all peatland categories, the occurring of Ca deficiency in the diet was pronounced. The highest prevalence of parasitic worms infection was found in cows raised in peat swamps. Bali cattle that maintained in different peatland categories generally showed different responses in nutrient adequacy and prevalence of parasitic worms infection. Keywords: Bali cattle, nutrient adequacy, parasitic worm, peatlands, prevalence

Abstract

The availability of pineapple seedlings in the field is a problem in the development of Smooth cayenne pineapple because of limited sources of planting material compared to the other types. Effort that can be done to solve the problem is to use the method of crown leaf-bud cutting. Propagation of pineapple (Ananas comosus L) with the method of crown leaf-bud cutting is not optimum so it can be optimized; one of them is by giving the duration of storage treatment and application of plant-growth regulators. The experiment was aimed to study the effect of crown storage duration and plant growth regulators on the growth of pineapple seedlings. The experiment was arranged in a nested plot design. Duration of crown storage for 2 (control), 10, and 20 days in room conditions at a temperature of 29-35°C and humidity of 46-70% as the main plot. The subplot was combination of indole-3-butyric acid (IBA) and 6-benzylaminopurine (BAP) with the concentrations: IBA 300 ppm and BAP 400 ppm, IBA 300 ppm and BAP 600 ppm, IBA 400 ppm and BAP 400 ppm, as well as IBA 400 ppm and BAP 600 ppm. The results of the experiment showed that the leaf-bud cuttings which stored for 10 days 57.34% were survived, 57.15% were sprouted, and 51.62% were rooted, while the control that survived, sprouted, and rooted did not reach more than 30%. The content of endogenous ABA in the crown leaf-bud shoots decreased significantly after being stored for 10 and 20 days, while the contents of endogenous auxins and cytokines were not different from the controls. Application of IBA 400 ppm combined with BAP 400 and 600 ppm increased the percentages of survived and sprouted cutting 1.5-1.7 times compared to control. Keywords: auxin, cytokines, exogenous hormone, endogenous hormone, vegetative propagation

Abstract

Aspects of litter productivity in fallow land in Manokwari, Western Papua need to be investigated because litter has the potential to increase soil fertility. The objective of this research was to count and estimate litter productivity in 15 years-fallow land in Womnowi, Sidey District, Manokwari. We used litter trap of 1 m2 in size with 2 mm mesh size. Nine litter traps were set under tree species, three replications of each tree species which have higher Important Value Index (IVI). Litters were weekly taken and oven dried until reaching the constant mass. Result showed that the dry masses of litters are not significantly different among three species. If the productivities are constant and probabilities of litterfall are same, the estimates of Dractontomelon dao have dry mass productivity rate (DMP) reaching 10.32 ton ha-1 year-1, followed by 8.98 ton ha-1 year-1 for Pometia pinnata, and 7.96 ton ha-1 year-1 for Octomeles sumatrana. Dry mass percentage (DMP) decreased in the order of P. pinnata > D. dao > O. sumatrana. We found negative linear regressions about water content of litter (WCL) and DMP at P. pinnata and O. sumatrana, but not for D. dao. These negative linear regressions can be used to estimate the rate of decomposition of each species. Keywords: linear regression, litterfall, secondary forest, soil fertility, Western Papua

Abstract

Potato is one of economically important crops in Indonesia. However, its production fluctuates since there are some factors affecting the yield. Recently, we found dwarf disease at potato central production area in Wonosobo and Banjarnegara Regencies in Central Java. So far, there is no information related to the yield loss caused by the dwarf disease on potato. Therefore, the research aimed to estimate the yield loss caused by the dwarf disease on potato in Central Java. The yield loss estimation was determined on some potato cultivations with different disease severities. The disease intensity was observed for five times with interval two weeks on six plots. The quantity and quality of potato yields, and selling price was calculated at the end of the observation and the correlation between the severity of disease and AUDPC (Area under disease progress curve) with yield loss was determined by regression and correlation analysis. The dwarf disease reduced plant height, individual and total tuber weight without affecting the number of tuber yield. The different of disease intensities in some area affected to the percentage of yield loss. The yield loss caused by dwarf diseases on individual potato plants up to 64.42%. Yield loss estimation caused by the dwarf disease in fields with different level of disease intensities ranged from 10.35-26.43%. Regression analysis between disease severities and yield losses showed the R square value at the level of 88.6% and a correlation at the level of 94.14%. These results indicated that the correlation between the severity of dwarf disease and yield loss is high. Keywords: disease severity, potato yield, selling price, tuber quality

Abstract

Myostatin (MSTN) gene acts as a negative regulator of muscle growth. The aim of the present study was to identify polymorphism of g.-371T>A in promoter region of MSTN gene in Indonesian beef cattle. Blood samples were collected from 191 cattle, including Bali (BL) (42), Madura (MD) (20), Pesisir (PI) (17), Katingan (KT) (16), Ongole grade (PO) (22), Pasundan (PD) (14), Sumba ongole (SO) (10), Brahman (BH) (17), Simmental (SM) (15), and Limousin (LM) (18). Polymorphism of MSTN gene was analyzed using PCR-RFLP (DraI) and direct sequencing methods. Results of genotyping g-371T>A were polymorphic (TT, TA, and AA genotypes) in Simmental, SO, and Katingan. The frequencies of alleles T and A were 0.83; 0.90; 0.97 and 0.17; 0.10; 0.03 respectively. The values of Ho and He were 0.06–0.20 and 0.06–0.28, respectively. The results of this study are in Hardy-Weinberg equilibrium (P> 0.05). Whereas in PD, MD, PI, PO, BH, LM, and BL were monomorphic (TT genotype). The result of sequencing the promoter region of MSTN gene found that mutations transversion was occurred in T to A at g.-371. It was concluded that g.-371T>A of MSTN gene was polymorphic which was potential to be used as genetic markers of muscle growth in SM, SO, and KT cattle. Keywords: SNP g.-371T>A of MSTN gene, Sumba ongole cattle, Katingan cattle, Simmental cattle

Abstract

Ketumpang (Tridax procumbens L.) contains bioactive compounds that can be used as natural insecticides. To reduce particle size, the extracts were prepared using nanoemulsion techniques. This study aims to determine the effect of nanoemulsion of intercropping leaf extract on behavior and mortality of crop caterpillars on mustard plants. This study used an experimental method with a completely randomized design (CRD) consisting of seven treatments and four replications. The treatments consisted of, K- = Administration of nanoemulsion extract at a concentration of 0% (K-), P1 = Administration of nanoemulsion extract at a concentration of 5%, P2 = Administration of nanoemulsion extract at a concentration of 10%, P3 = Administration of nanoemulsion extract at a concentration of 15 %, P4 = Administration of nanoemulsion extract at a concentration of 20%, P5 = Administration of nanoemulsion extract at a concentration of 25%, and K + = Administration of the chemical insecticide deltamethrin at a concentration of 0.04% as a positive control. Data were analyzed using descriptive and analysis of variance, as well as further tests at α=0.05. The results showed that administration of nanoemulsion ketumpang leaf (Tridax procumbens L.) extract caused behavioral changes (eating, resting, and moving) of caterpillar crop which became inactive and increased mortality of crop caterpillar. Nanoemulsion extracts of overlap leaves could be used to control crop caterpillars. Keywords: crop caterpillars, ketumpang leaf, mustard, nanonemulsion

Abstract

This study was conducted to evaluate physical properties and nutritive values of white rats (Rattus norvegicus) diets using different screen sizes of ground corn and different die sizes of the pellet. The experiment was divided into two trials. The first experiment aimed to find the effect of different particles of corn and die sizes of pellet on the physical properties and quality of white rat diet. The experiment consisted of 4 treatments and 4 replications namely, P1 (screen 3 mm and die 4 mm), P2 (screen 3 mm and die 16 mm), P3 (screen 5 mm and die 4 mm), and P4 (screen 5 mm and die 16 mm). The parameters measured were Pellet Durability Index (PDI), Specific density, Loose Bulk Density, and compacted Bulk Density of the pelleted diet. The second experiment was feeding trial to measure the performance of the white rats fed the pelleted diets. A total number of 20 white rats were used and divided into four treatments of the first experiment and replicated 5 times. The parameter measured were feed intake, final body weight, as well as the digestibility of dry matter and organic matter. Result of the experiments showed that the pellet durability index was significantly affected by the particle size of corn and the diameter of the pellet (P<0.01). In the feeding trial, the rats fed pelleted with the die of 16 mm resulted the highest feed intake (P<0.05). The P1 diet resulted the best physical pellet quality whereas P2 resulted the best performance of the experimental rats fed the pelleted diet. It can be concluded that to produce the best pelleted diet of rat, the ingredients should be ground with 3 mm screen size and the pellet was produced with the die diameter of 16 mm. Keywords: die diameter, particle size, pellet durability index, pellet physical quality, white rats
