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

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

This study aims to reanalyze the GeoGebra-assisted mathematics learning in improving students' High Order Thinking Skills. In addition, this article also discusses the ability of teachers and students with HOTS abilities to learn mathematics without the help of GeoGebra. GeoGebra is used to help teach and learn mathematics to make it easier for students to understand and construct the material. The method used in this research is meta-synthesis as a qualitative systematic review by analyzing ten journals relevant to the research title. The first step is to formulate the research problem, then proceed with tracing the existing studies that are relevant to the research title which will then be analyzed in depth. The data collection technique used non-test by reviewing previous research with similar problems to obtain results and conclusions. The journals analyzed in this study were ten nationally accredited journals that discussed GeoGebra-assisted mathematics learning and HOTS. The results of the analysis of ten related journals concluded that GeoGebra-supported math learning can improve the skills of HOTS students. Teachers must improve their understanding of HOTS and the need for training in designing lesson plans and making HOTS questions for teachers and students.
