Abstract

 ABSTRACTThe yam bean seeds are formed in relatively long pods containing between 6-12 seeds/pod. A total of six local yam bean accessions from Indonesia was studied for its seed position in pod related to seed viability and vigor. Field research was carried out in Malang (Indonesia) from May - October 2016. Twenty five matured pods were detached from each accession. Each pod was divided into three parts, i.e. base, middle, and tip part. The seeds of each part are mixed and taken as many as 20 seeds for germinating. The design was a completely randomized design with two factors and repeated three times. The first factor was three seed positions (base, middle, and tip) and the second factor was six accessions of Indonesian local yam bean. The analysis of variance showed that seed position had significant effect on individual seed weight, leaf length, leaf width, leaf shape index, seedling dry weight, and root dry weight. Seeds derived from the midde of the pods produce the highest leaf length, leaf width, leaf shape index, seedling dry weight, and root dry weight. The parameters of seed viability and vigor were not affected by the seed position in the pods. Therefore, the seed viability and vigor of yam bean plant in the field can be produced from the seeds derived from the tip, middle and base of the pod. Keywords: seed position, viability, vigor, yam bean

Abstract

The contribution of biodiversity to economic development, social and ecological in Indonesia today and thefuture are already being felt very real. Unfortunately, as well as economic development approach to the greeneconomy that appears on the answers rampant deforestation and forest degradation, biodiversity atmospheretoday in Indonesia is under pressure and decrease impact on the species and environmental balance problemsand poverty. Besides the problem of public funding also be other problems. In this case, government role to bevery significant through the Transfer to the Regions. By using the methodology analysis desk study, it can berecommended that General Allocation Fund (DAU) is the main policy priority for funding biodiversity, throughthe addition of indicators of the Fiscal Needs (KbF). Other policy options are DAK mechanism throughimprovement criteria.Keywords: Biodiveristy, General Allocation Fund (DAU), Specific Allocation Fund (DAK), Forestry,Environment

Abstract

ABSTRACTEffectivity of EDTA (EthylenediaminetetraceticAcid) in Increasing Lead Accumulationof Saccharum spontaneum Grown Under Gold Mine Waste. Lead (Pb) isknown as one of a major metal contaminant in mine tailing. This metal has low solubility,and in many cases, is not readily available. In most soils capable of supporting plantgrow, the soluble Pb2+ levels are relatively low and will not promote substantial uptake bythe plant. In addition, many plants retain Pb2+ in their roots with only minimal trabsportto the aboveground plant portions. Therefore, it is important to find ways to enhance thebioavailability of Pb2+ or to find specific plants that can better translocate the Pb2+ intoharvestable portions for phytoremediation. The success of Pb phytoremediation is tohave significant Pb availability as well as a large quantity of plant biomass with high rateof growth. This experiment was conducted to obtain both purposes. Saccharumspontaneum which proven tolerant and dominant in contaminated area as well as potentialin producing high biomass was used in this research.The plants were grown in wastemedia added by 100 ppm, 200 ppm and 300 ppm of Pb. Ethylenediaminetetracetine Acid(EDTA) was applied to increase Pb availability and plant uptake as well as translocationto the aboveground portions. The results showed that the plant still capable of growingunder the highest level of Pb. EDTA increase Pb availability and plant uptake. Pb accumulationin the aboveground biomass of EDTA treated plants were relatively higher thanuntreated plants.Key words: Timbal, EDTA, phytoremediation

Abstract

This study is aimed to determine the effect of additional concentrate feed on the physical and chemical characteristicsof sunda porcupine meat. The material used is eight sunda porcupines (two males and six females) divided into twogroups of ration treatment, namely T0 (control ration) and T1 (T0 + koi fish pellets). Four porcupines (one maleand three females) were given control ration (T0) and four porcupines were given rations T1. The experimental designwas a completely randomized design. The meat physical characteristics measured were pH, tenderness, cookingloss, water holding capacity (WHC), meat color, and fat color. While meat chemical characteristics analyzed werewater content, ash, protein, fat, gross energy, calcium (Ca), phosphorus (P), iron (Fe), the content of fatty acids(EPA, DHA, Omega-3, Omega-6, Omega-9, and cholesterol), as well as the composition of amino acids. Data wereanalyzed by analysis of variance. The results showed no significant differences (P> 0.05) between male and femaleporcupine with both ration treatments (T0 and T1) on pH, tenderness, cooking loss, WHC, meat color, and fatcolor. The addition of koi fish pellets in the ration T1 decreased pH value (65.76) and cooking losses (37.88%), andincreased WHC porcupine meat (23.59%). Porcupine meat is quite tender with tenderness values of 3.63 kg / cm2(T0) and 3.26 kg / cm2 (T1). The averages of water content, ash, protein, fat, energy, Ca, P, Fe of porcupine meatwere not significantly different (P>0.05) in both treatments T0 and T1. The averages of fatty acids contents of porcupinemeat with T1 was not significantly different (P>0.01) from that of T0, but there was an increase in the concentrationof EPA, DHA, omega-3, omega-6, omega-9, and cholesterol in treatment of T1. Cholesterol content ofporcupine meat was lower than that of beef, pork, lamb, sambar deer, and java deer. No significant effect (P> 0.05)on content of amino acids in meat porcupine with T1 compared to that of T0.Keywords: Physical-chemical characteristics, meat, concentrate feed, sunda porcupine

Abstract

Quality of Meat and Its Other Body Parts of Sunda Pangolin (Manis javanica Desmarest, 1822). Sunda pangolin (Manis javanica Desmarest, 1982) is a scaly mammal protected and endangered due to illegal hunting and uncontrolled trade. Because this animal?s biological information has not been widely known, it is necessary to study its various aspects. This study aims to determine the quality of meat and its other body parts of sunda pangolin.Research material used are meat and its other body parts of two male pangolins. The observed chemical composition includes water content, ash, protein, fat, energy, amino acids, fatty acids, cholesterol, EPA, and DHA. Physical quality includes pH and cooking loss. The results showed pangolin meat contains 73.99% water, 0.98% ash, 22.87% protein, 1.63% carbohydrate, 1027.70 cal / g gross energy, and cholesterol 18.89 mg/100 g. The concentrations of essential amino acids of pangolin which are high compared to other wildlife are arginine (1.63%), threonine (1.04%), isoleucine (1.03%), and leucine (1.88%). The content of fatty acids of pangolin meat are lauric (0.30%), myristic (1.20%), palmitic (24.90%), stearic (5.76%), oleic (24.25%), linoleic (2.99%), and linolenic (0.31%). Total EPA and DHA are 9.16 mg/100 g and 16.64 mg/100 g,respectively. Pangolin scales contain protein, gross energy, calcium, phosphorus, 14 kinds of amino acids, EPA and DHA higher than those of its meat. Protein content of pangolin?s body parts from the highest to the lowest is scales > tongue > meat > liver. The pH value of pangolin meat is 6.17 and its cooking loss is 35.12%.Keywords : nutritional values, meat, scale, Manis javanica

Abstract

ABSTRACTSmall mammal community in various habitats at Apuy track and Linggarjati trackof Gunung Ciremai National Park. Distribution of small mammals at Apuy track(west slope) and Linggarjati track (east slope) of Gunung Ciremai National Park arecorrelated with their habitats. Traps, mist nets and observational methods were conductedto record small mammals from seven different habitats. To interpret such patterns, weconducted cluster analysis based on Jaccard index of similarity resulting five distinctgroups. Species diversity for each habitat differs significantly indicating great diversitydifferences between habitats. Common species appear to occupy disturbed area alongthe habitats examined, where as rare species tend to associate with more distinctivehabitat types. The results seem to suggest that forest may still consitute an substantialcomponent for the preservation of small mammals.Key words: ciremai, small mammals, habitat, distribution, zoning.

Abstract

ABSTRACTOn CoP 18 which will be held in Sri Lanka in 2019, house gecko was proposed to be uplisted up listed from the non-appendix status of CITES to be included the list of CITES appendix II on the reasons that the hunting of the reptile was very large and uncontrolled. In order to anticipate the up listing of house gecko status, LIPI as a Scientific Authority in Indonesia recommended quota for house gecko in 2019 to be 1,800,000 individuals. To see that such a quota does not have a negative impact on the population of house gecko in the wild, a survey was conducted by using the close questioner system method by visiting housing in a village; where in this survey the villages were located at the foot hill of Gunung Karang, Pandeglang Regency, Banten Province. The survey was conducted on March 18 to April 1, 2019. The total number of villages visited was 8 villages which were divided into three sub-districts. The total area surveyed in 8 villages was around 94.5 hectares.  The total number of houses visited was 740 houses; the total number of houses that contained the house gecko was 211 houses. The total number of house gecko by interviewed was 260 individuals, while the total number of house geckos by observed was 88 individuals. The survey results obtained an average population density of house gecko by interviewing eight villages was 3.66 individuals/hectares, while the observation results were 1.15 individuals/hectares. The approach to the average population density of houses gecko by interviewing with the results of 3.66 individuals/hectares was assumed to be the density that was close to the logical number.  Extrapolating the density of house geckos in Pandeglang Regency which covers an area of 229,071 hectares excluded paddy field area was considered to be inhabited by house gecko, so the extrapolation of the number of house geckos in Pandeglang Regency is around 838,399.86 individuals.  Keywords: Gekko gecko, house gecko, Java, population

Abstract

ABSTRACTGenetic improvement of taro (Colocasia esculenta L.) is one of important research program to increase productivity and give better cultivation on the marginal land. Induction of polyploid plants is a method useful to increase genetic diversity. The aim of this research was to induce polyploid taro by oryzalin treatment. Polyploidy was induced from in vitro diploid taro ?bentul? using oryzalin at 7.5; 15; 30; 60 and 75 ?M soaked for 3 days. Regenerated shoots were grown on MS medium containing 2 mg/l BAP, 1 mg/l thiamine and 2 mg/l adenine. Shoot growth was recorded four weeks (subculture-0), eight weeks (subculture-1) and twelve weeks (subculture-2) after treatments. The results showed that survival rate of treated shoots was 100%. Higher oryzalin concentration reduced the proliferation of shoots, petiole length, numbers of leaves as well as the numbers of roots. Ploidy levels analysis determined by flowcytometer for 122 plantlets were investigated. The results indicated that control shoots were diploid. All treated shoots were polyploids. Oryzalin at 60 ?M gave 50% of tetraploid planlets, 30 ?M of oryzalin gave 5.71% hexaploids, 60 ?M of oryzalin gave 9.09% octaploids. All acclimatized plantlets gave 100% survival rate.Keywords : Colocasia esculenta L., taro, in vitro induced polyploidy, oryzalin
