Abstract

Wastes in the form of skin derivatives from leather tanning industries remain serious problems if not managed properly and quickly, since they can cause environmental pollution. This research aimed at studying the influence of base type and concentration for the hydrolysis of trimmed collagen from pickled sheepskin to the yield and properties of gelatin, as well as the gelatin’s potential as flocculant. The hydrolysis of trimmed collagen from pickled sheepskin was performed using KOH or NaOH solution, each with varied concentrations of 1, 2, 3, and 4% w/v, for 16 hours. The extraction of the resulting gelatin was performed using water (2.5 water part : 1 waste part), at 70-80 oC, for 3 hours. The results show that the yield of gelatin from hydrolysis using KOH (16.50-28.60%) is lower than that using NaOH (23.68-34.42%). The water and fat contents of the resulting gelatin were relatively similar, while the protein content from KOH treatment was higher than that from NaOH treatment. Hydrolysis with KOH 1% and NaOH 1% and 2% resulted in gelatin that can be used as flocculant. Hydrolysis with NaOH 2% was the best treatment to produce gelatin as flocculant.Keywords: pickled sheepskin, trimming waste, hydrolysis, gelatin,  flocculant.ABSTRAKLimbah berupa kulit turunan dari industri penyamakan kulit masih menjadi masalah serius apabila tidak ditangani secara tepat dan cepat, karena dapat menimbulkan pencemaran lingkungan.

Abstract

BOD, COD, phenol and ammonia-free in the effluent of hospitals wastewater often exceed the quality standards. This was due to less optimal biological processes to degrade the pollutants. So we need an efforts to find optimal process conditions through the engineering process and the factors that affect the biodegradation of pollutants. On the other hand, AF2B reactor containing biofilter with bee nest shaped has a large specific surface area so as to maximize the biodegradation process of pollutants by microorganisms. While bacteria consortium consisting of several types of bacteria have a greater capacity than a single bacterium in the degradation of pollutants. The research aims to determine the effect of starter volume and air flowrate to decrease the concentration of pollutants (BOD, COD, phenol and ammonia-free) in AF2B reactor batch using a bacterial consortium. The research was conducted in three phase which are the making of growth curve, acclimatization and biodegradation of pollutants in an AF2B reactor batch using a bacterial consortium. The experiment variables are the starter volume (85%, 75%, 65% in volume), and the air flowrate (2.5; 5; and 7.5 liter/min). Materials used are hospital waste water and bacterial consortium. The experiment begins with setting up the AF2B reactor containing biofilter with bee nest shaped and then filled it with a starter from the acclimatization process on a given volume and followed by supplies of air at a certain flowrate. Then hospital waste water and 5% of nutrients were added till reach 10 liters of total volume in reactor. Samples were taken every 30 minutes for up to 360 minutes of biodegradation process. The samples were then analyzed its pollutants concentration (BOD, COD, phenol and ammonia-free). The BOD concentration was analyzed using Winkler bottles method, COD using open reflux method, while phenol and ammonia-free using UV-Vis spectrophotometry method. The results showed that the starter volume and air flowrate affect the decrease of pollutants concentration till reach quality standard, which at starter volume of 85%, air flowrate of 7.5 liter/min and biodegradation time of 360 min can reduce the BOD, COD, phenol, and ammonia-free to 92%, 86%, 88% and 76% respectively.

Abstract

RFLP analysis of mitochondrial DNA cytochrome b gene was conducted to determine the diversity, status and close genetic relationships in a population of Batur sheep with the Merino and local sheep breeds (Garut, Thin Tail and Fat Tail). The research used genomic DNA of 27 samples of Batur, 15 Merino, 17 Garut, 15 Thin Tails and 15 Fat Tails sheep. The PCR process used two types of 25 nucleotides primers. The PCR products were checked by using 2% agarose gel electrophoresis. The PCR DNA fragment was digested by using Hae III at 37 oC and incubated for 10 hours. Similarities and differences of cytochrome b gene RFLP bands between individual samples of one and across populations, genetic distance, and close genetic relationship, were identified. The PCR process of the cytochrome b gene metochondrial DNA of the 45 samples of sheep yielded 359 bp band types. The digestion (cutting) of the PCR products of mitochondrial DNA cytochrome b gene by using Hae III resulted in RFLP band profiles of 128 up to 231 bp polymorphisms of cytochrome b gene. Although the Hae III restriction enzyme recognized only one restriction site, however, between samples of Batur, Merino, Garut, Thin Tail, and Fat Tails, there were monomorphism and polymorphism Hae III loci.Key Words:  RFLP, cytochrome b gene, genetic markers, genetic similarity, Batur sheeAnimal Production 13(3):156-165 (2011)

Abstract

A α-amylase is included in hydrolase’s enzyme (E.C. 3.2.1.3), which catalyzed the breaking down of α-1,3-glycosidic bound on amylase chain and produced glucose as end product. In mammalian and poultry, α-amylase enzyme has a function as starch breaking down or changed glycogen to glucose. It was used as energy resource in the body. A α-amylase enzyme is protein that resulted in expression from one or several genes, so that has various characteristics among individual. To study the existence and the characteristic of α-amylase enzyme, therefore it has been conducted a research about the connection of α-amylase enzyme unit number  with glucose content in Tegal, Magelang and Mojosari duck blood (each of them consisted of 28 birds). This research used Completely Randomized Design (CRD) with seven replicates for each treatment. The result research showed that either the unit number of α-amylase enzyme activity or glucose content in these local breed of duck has a highly significant different (P<0.01). This result showed that genetic factor (breed of duck) has influenced either enzyme unit number or their catalytic activity on substrate, so the capability to form blood glucose inter breed of duck also different. It was suggested that their enzyme characteristics have strong connection with the sequence of amino acid as α-amylase enzyme protein composer, which was the result of gene expression. From the result, it was concluded that the unit number and catalytic activity of α-amylase enzyme and blood glucose content in the breed of local duck was affected by genetic factor (breed of duck).

Abstract

Maternal serum of thirty nine ewes were used to study hematological and antibody responses of chicken injected with antigen protein of specific LDH obtained from sheep with different littersizes (prolific type). The prolific type of ewes was determined base on littersize (LS), which were low ( 1 ≤  LS ≤ 1.5), medium ( 1.5 < LS ≤ 2.0), and high (LS > 2.0). There were ten ewes carrying specific LDH protein. The number of animals of low, medium, and high prolific-type ewes was 3, 5, and 2 heads, respectively. The serum was used to produce antigen and injected to chicken to promote antibody production of anti LDH. The results of research showed that different prolific-type has no significant (P>0.05) effects on hematological and antibody titer of chicken.  However, hematological status of chicken injected with specific LDH antigen was significantly (P<0.05) higher than control. It can be concluded that production of specific protein anti LDH can be done in layer by injection of antigen from ewes. Product of specific protein anti LDH of prolific ewes still needs field test for its accuracy for selection of ewes with different prolific type.
