Abstract

Biogas is a renewable energy which can be used as alternative fuel to replace fossil fuel such as oil and natural gas . Recently, diversification on the use of energy has increasingly become an important issue because the oil sources are depleting . Utilization of agricultural wastes for biogas production can minimize the consumption of commercial energy source such as kerosene as well as the use of firewood . Biogas is generated by the process of organic material digestion by certain anaerobe bacteria activity in aerobic digester . Anaerobic digestion process is basically carried out in three steps i.e. hydrolysis, acidogenic and metanogenic . Digestion process needs certain condition such as C : N ratio, temperature, acidity and also digester design . Most anaerobic digestions perform best at 32 - 35°C or at 50 - 55°C, and pH 6 .8 - 8 . At these temperatures, the digestion process essentially converts organic matter in the present of water into gaseous energy . Generally, biogas consists of methane about 60 - 70% and yield about 1,000 British Thermal Unit/ft 3 or 252 Kcal/0.028 m3 when burned . In several developing countries, as well as in Europe and the United States, biogas has been commonly used as a subtitute environmental friendly energy . Meanwhile, potentially Indonesia has abundant potential of biomass waste, however biogas has not been used maximally . Key words : Biogas, renewal energy, anaerobic

Abstract

The ban against using antibiotics has led to increase the use of alternative additive substances as antibiotic. The alternative additives that can be used as antibiotic are probiotic and prebiotic. Both components can be used separately or together as synbiotic. Probiotic and prebiotic can modulate the ecosytem of intestinal microflora that is potential to affect the health and performance of host. Probiotic and prebiotic have been widely used abroad because of their positive effects, but the research and the use of these components in Indonesia are limited, eventhough abundance of raw material that can be used are available. The research dealing with probiotic and prebiotic as additive is necessary to be improved to obtain the efficient and practical production method, which can be implemented to give an economic impact on livestock industry.

Abstract

The investigation was carried out to study the utilization of oligosaccharides from sweet potato as feed additives to improve the performance of laying hens. Oligosaccharides were extracted from sweet potato using 80% ethanol. Extractant and residue were evaluated as feed additive. Ninety six of 18 weeks old laying hens from CP 909 Isa Brown were randomly distributed into four treatments with six replicates and four laying hens per replicate. The treatments were: Ro = Control without oligosaccharides, R1 = R0 + 0.1% of extract of sweet potato. R2 = R0 + with 0.2% of residue of sweet potato, and R3 = R0 +  with 0.2% of commercial FOS. The evaluations were carried out up to 25 weeks of egg production. The data were evaluated with statistical analysis using SAT. The results showed that egg production and FCR of R1 and R2 were better than R0 (P < 0.05). The treatments were not significantly affected feed consumption. In conclusion, addition of extract or residue of sweet potato improved (P < 0.05) egg production and FCR of layers compared to control diet.

Abstract

The investigation was carried out to study the effect of oligosaccharides from soybean meal (SBM) and sweet potatoes as feed additives on feed to improve the productivity of broiler. The amounts of 704 day-old chicks from Arbor Arcres were randomly distributed into 16 treatments with 4 repetions  and with 11 chicks in each pens. The treatments  were: 2 level of sweet potato oligosaccharides (0.1 and 0.2%), 2 levels of residue of  sweet potato extracts (0.4 and 0.8%), 2 levels of SBM oligosaccharides (0.1 and 0.2%), 2 levels of residue of SMB extracts, 2 levels of MOS commercial (0.01 and 0.02%) 2 levels of commercial inulin (0.1 and 0.5%), 2 levels of commercial FOS (0.2 and 0.4%) and control with and without antibiotic. The results showed that better FCR (P < 0.05) was seen on the addition of 0.2% sweet potato oligosaccharides at 3 weeks trial, meanwhile on 0.1% addition was able to improved the absorption of Ca and P. The trial up to 5 weeks, only treatment with 0.8% of residue have a better FCR value (P < 0.05). The effect of utilization of SMB oligosaccharides was only observed on 0.8% residue at 5 weeks trial which have a better FCR value. It could be concluded that the extract of oligosaccharides from soybean meal and sweet potatoes could improve the effisiency of broiler feed.

Abstract

An experiment was carried out to evaluate the effectivity of an enzyme complex produced by Eupenicilium javanicum BS4 on the performance of laying hens fed with different feed ingredients. Three diets were formulated with similar nutrients (protein, ME, digestible amino acids, Ca and available P) value to meet the nutrient requirement of laying hens.  Diets were formulated based on maize, palm kernel cake (PKC) or rice bran.  The diets were either supplemented or not with BS4 enzyme complex and fed to Isa Brown pullet from 19 to 37 weeks old. Each diet was fed to 24 birds and the performances were recorded. Data were analysed statistically with 2 X 3 factorial design with six replicates. Results showed that supplementation of BS4 enzyme into laying hens diet did not influence body weight change, feed intake, mortalities, egg weight and egg shell thickness but significantly increased egg production (P&lt;0.05) and the FCR (P&lt;0.01) in any feedstuff tested. It also improved egg yolk colour score on diet contained 20% PKC. Laying hens fed 20% PKC produced more eggs than those fed maize or rice bran. The egg shell of laying hens fed rice bran were thicker than those fed with maize or PKC. It is concluded that BS4 enzyme complex is effective when supplemented into laying hens diet.

Abstract

Calculation of carbon stocks using allometric equation system is done to get the value of carbon stocks in smallholder rubber plantations in Cempaka district, Banjarbaru City South Kalimantan needs to be done in order to know the carbon stocks contained in the smallholder rubber plantations.  Based on the statistical report plantation Banjarbaru City first quarter of 2013, the peoples rubber plantation area of 986 hectares.  However, data obtained from field surveys note that the data are actually rubber plantation area of 1318.61 ha.  This study aims to determine the amount of carbon stocks in jungle rubber at different age levels and determine other factors that affect carbon stocks in jungle rubber.  The methods of this study includes data collection and determination of the point of the plot as well as the selection of a plot point.  Primary data collection is done by taking the coordinates of the field (the survey) using a GPS (Global Positioning System), and the data analysis was conducted on the data collection for the measurement of carbon stocks above the surface of the carbon on the surface and below the surface measuring carbon stocks.  The results showed that the highest carbon stocks contained in the 7-year age group with a score of 716.61 Mg carbon stocks / ha followed by 5-year age group was 685.21 Mg / ha, 3-year age group was 603.51 Mg / ha and the smallest to the carbon value of 585.62 Mg / ha.  While based on the factors that influence the obtained results that the pH is tolerated for acid soil types, categorized as very low C Organic, Organic materials in the high category, total N and P were categorized very low, K can be categorized as high.  All these factors are still can be considered good for the growth of rubber trees until they reach the age of 30 years.  Concluded that the more composition and structure of rubber gardens stands then the greater carbon storage in stands in people rubber plantation area at the Cempaka district Banjarbaru City and soil conditions can be categorized as land that can still be used for the growth of rubber trees.
