Abstract

            Vegetation that grows naturally in certain areas is a reflection of the interaction of various environmental factors and may change at any time. Under oil palm trees, there are several types of vegetation that have the potential to be used as animal feed, but it has not been identified yet. This study aimed to examine the types of vegetation that grows under the oil palm trees, and could potentially be used for animal feed. Observations were conducted on 3 groups of oil palm plantations aged above 10 years which belong to:  i.e. smallholder oil palm, private estates, and state estates company. In each group, it was taken 8 plots so there were 24 plots in total. Parameters observed were the types of plants (i.e. grass, legume, and weed), plant nutrient content (determined by using proximate analysis), microclimate and soil organic matter content (C and N), and soil pH. Collected data were analyzed descriptively, and were followed by a t test.   Results showed that herbages grow in palm-oil plantation in the Ness village are more various than that of in the Arang-arang village.  Ottocloa nodosa and Eulisine indica are two grasses species that might be potential in the Arang-arang village which has a pity soil type, while Leersia hexandra, Paspalum sp., and Ottocloa nodosa are species of grasses which grow in the Ness village which has a yellow-red podsolic soil type.  The existence of Melastoma malabathricum in the Arang-arang village should be considered as this species contains poisonous substances.  Calopogonium sp. and Mimosa sp. are spesies of legumes that could be developed in palm-oil pasture to improve N content of herbages.  Nitrogen or mineral fertilization might be needed to improve soil fertility of different soil types.Key words: oil palm, vegetation, weeds, animal feed, soil

Abstract

The objective of this research was to determine the genetic variation of the Maleo (Macrocephalon maleo) based on blood protein polymorphism. Material of the research was blood of Maleo coming from different original habitat, coastal and inland area. PAGE-TYLE (Polyacrilamide Gel Electrophoresis-Thin Layer Electrophoresis) was used in this research. Parameters observed were genotype at four locus Pre Albumin (PAlb), Albumin (Alb), Ceruloplasmin (Cp) and Transferrin (Tf). The obtained various data were used to analyze gene frequency, individual heterozygosity as well as average heterozygosity. The result showed that gene frequencies at allele A and B of four locus Maleo both  in coastal and inland habitat were the same at PAlb locus and Tf locus, that was 0.5; Alb locus was 0.33 vs 0.67 and 0.67 vs 0.33, respectively; Cp locus was 0.5 vs 0.67 and 0.5 vs 0.33, respectively. Individual heterozygosity of four locus Maleo in coastal and inland habitat were the same at PAlb and Tf  that was 0.5; Alb was 0.4555 respectively; Cp was 0.5 vs 0.4555 respectively. Average heterozygosity in coastal and inland Maleo were 0.3911 and 0.3822, respectively. In conclusion, Maleo in coastal and inland habitat showed the same value of diversity relativity due to uncontrolled assortative mating.Key words: Maleo (Macrocephalon maleo), genetic variation, polymorphism blood protein

Abstract

Lower beef cattle productivity in South-East Sulawesi caused by the lack of knowledge and skill of farmers to utilize existing feed resources. This research specific objectives : (1). to identify local feed of beef cattle in South-East Sulawesi, (2) to formulate local feed become the complete rations for fattening, (3) to analyse the nutrient value of available feeds resources. This research was applied through a survey to identify local feed at eight districts andtwo cities in South-East Sulawesi, namely Kendari and Bau-bau cities, districts of Konawe South, Konawe, Bombana, Kolaka, Muna, and Buton. The Research was conducted from April to November 2007. The Laboratory analysis was conducted to know nutrient value of feed, and thus can be determined the local feed feasibility for being the ration formulation. The research result indicated that: (1) the local feed which can be identified consist of 30 types coming from waste of agriculture, plantation, industry, market and household, (2) the local feed which was available in big supply and had potency to be processed as complete ration for fattening beef cattle were cacao pods, sago waste, tofu waste, paddy bran and yellow corn, (3) the analysis of some local feed for beef cattle showing a quite higj nutrient value with the range of protein content around 2 - 9% as well as total digestible nutrient approximately 15 - 90%. The other content of nutrient and mineral was also sufficient for supporting the livestock growth.Key words: Identification, local feed, nutrient value

Abstract

Research of macroalga diversity and bioactivity was conducted from February to September 2016 at Wediombo beach, Gunung Kidul district. The used sampling method was “metode jelajah” and the environmental parameters measured include temperature, salinity, depth, pH, turbidity, dissolved oxygen (DO), and concentration of nitrate and phosphate. Identification was based on morphological characteristics. Extraction sample was stratified using ethanol and ethyl acetate. Method of HTS (High Throughput Screening) was applied to test the potential of active compounds. Antimicrobial Test was conducted with cell growth indicators (MTT), while the indicator DPPH was used for the antioxidant test (80mg / 100ml), and TLC and GC-MS for profiling the active compound. Seventeen species macroalgal were found at the shore of Wediombo, includes: Rhodophyta (7 species), Phaeophyta (5 species) and Chlorophyta (5 species) of which were dominated by macroalgal on coral reefs. Nine macroalgae found to have antioxidant activity (Acrocystis nana, Caulerpa sp., Chaetomorpha crassa, Dictyota sp., Gracilaria canaliculata, Gelidiella acerosa, Sargassum sp., Turbinaria sp. and Ulva lactuca) and 3 macroalgae (Boergesenia forbesii, Halymenia maculata and Palisada concreta ) did not possess the activity. Macroalgae which were tested for microbial activity, generally had antimicrobial against C. albicans and Shigella sonnei except E. coli. Results of TLC indicated that all of macroalgal had active compounds: terpenoid, glucose, flavonoids, phenols and amino acids but only few of them contained saponin, based on GC-MS test, Acrocystis nana, Zanardini was found to contain 1-Octadecyne (17.78%), Octadecanal (17, 83%) Dicholesteryl succinate (37.53%) and Cholestan-3-one, 4-methyl (26.86%) had the potential to be antimicrobial and antioxidant as well as bioenergy sources. Key words : Macroalga, High-Troughput Screening,  metabolites profiling
