Abstract

The aim of this study was to obtain the profile of physiological hematology (erythrocyte, PCV, Hb, MCV, MCH, MCHC, and leukocyte) and the profile of ratio between neutrophil and lymphocyte of long-tailed macaque (Macaca fascicularis) in different microclimate conditions due to the room's temperature and humidity setting. The symptom of stress was also observed in this study. The research used 10 male macaques aged of 4 until 5 years old which placed in room temperature and humidity of 29,00±1,95°C and 79,52±1,57% respectively 7 days for adaptation period. Further more, the room temperature and humidity were set into 25,79±1,16°C and 80,19±9,05°/o during 14 days for treatment period. For the last treatment, macaques were reconditioned in room temperature and humidity of 29,00±1,95°( and 79,52±1,57°/o during 14 days for post-treatment period. Blood samplings were collected through femoralis vein on last day of adaptation period, continued with treatment and post-treatment periods as the day 1, 4, 7, 14, and 28. The results showed that there were not significant difference by room temperature and humidity setting to hematology and neutrophil: lymphocyte ratio. It could be proven by all parameters score obtained were still in normal ranges compared to literatures. There was also no stress symptom based on neutrophil:lymphocyte ratio measurement. Condition with room temperature and humidity of 25,79±1,16°C dan 80,19±9,05% regarded as the most suitable condition for long-tailed macaque'slife.

Abstract

Jatropha curcas"meal (JCM) is very potential as protein source for poultry. The JCM contained high crude protein, i.e. 56,4-63,8% (without hull) and 22,39-31,41% (hulled JCM). JCM serves as a highly nutritious and economic protein supplement in animal feed, if the toxins and antinutrients contained in the JCM are removed. The toxic compounds isolated from jatropha seed include curcin, phorbolesters, and the antinutrients include antitrypsins, tannin, saponin, phytic acid, and high fiber. The objective of this research was to evaluate the effect of feeding fermented JCM on the performances of kampong chickens. In this study, tempeh fungi (fungi using in fermenting soybean) used to ferment the JCM. Two hundred kampung chickens were used in this experiment and reared from day old up to 10 weeks of age. The data analyzed with a Completely Randomized Design with 5 treatment diets and 4 replications, with 10 birds in each replicate. The experimental diets were: TO (the control diet, without Jatropha curcas meal), T1 (the diet contained 5°/o untreated Jatropha curcas meal), T2 (the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton of feed), T3 (the diet contained 5°/o fermented Jatropha curcas meal + 1000 FTU phytase), and T4 {the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton + 1000 FTU phytase). The results showed that there were no significant difference on the parameters observed due to the treatments. Feeding fermented Jatropha curcas meal supplemented with cellulase+ phytase{T4) yielded the final body weight and feed conversion ratio similar to those the control {TO) diet. There was no mortality observed in all treatments. Using JCM 5% in the diet is safe for the kampong chickens.

Abstract

Mining activities could adversely affect the environment if the waste it generates is not processed properly. Negative impacts include disruption of natural ecosystems in the form of changes in soil structure resulting morphology and physical conditions, chemical and biological soil becomes worse. Tailings are mineralmineral/ logam-logam composite weight from mining activities, has a sandy texture. Planting crops gmelina (Gmelina arborea Roxb.) On the media tailings with the addition of NPK fertilizer and composted manure is expected to improve the physical properties, chemical and biological soil tailings as a medium for plant growth in land revegetation efforts. Experimental design used in this study was factorial design with two factors. The first factor is fertilizer NPK with 4 level and the second factor is the compost with 4 level. The interaction between NPK fertilizer and compost that give real effect on the growth of both high and diameter gmelina. So that the resulting growth in both fertilizer interaction produces a real growth.

Abstract

Quality is an absolute requirement used by product to compete in the global market. Therefore, as the competition is getting more tight , high-quality gambier products become an absolute demands that must be met. One of the steps that must be taken is continuous technological improvement. In this study, quality analysis of various raw gambier samples of Lima Puluh Kota regency and the Padang City in West Sumatera, and Musi Banyu Asin regency in South Sumatra was done. The results of dimensional measurement and weighing samples of Bootch Gambier, Lumpang Gambier, Wafer Block and Stick Gambier showed that the quality of raw gambier were very various. The variation occured because the drying process and storage of gambier were not good enough. The proximate analysis data showed, in terms of ash content, only two types of Gambier samples (Bootch CVR Gambier and Wafer Block CVR Gambier) that met quality requirements, whereas the Coin Gambier and Bootch CVA Gambier had a very high ash content (38.93 percent and 75.64 percent).

Abstract

CRD is chronic respiratory disease in chicken caused by infection of Mycoplasma gallisepticum (M gallisepticum) and E. coli. Rio-prospective of jahe for controlling the disease was investigated through the study of antibacterial activity against M. gallisepticum of fresh ginger juice extract and fraction of hexan, ethyl acetate, methanol and water against M. gallisepticum and E. coli. The results showed that the juice of fresh ginger inhibited the growth of M. gallisepticum with the minimum inhibitory concentration that could inhibit the growth was 10 °/o. The fractions that effectively inhibited the growth of M. gal/isepticum are hexan fraction and water fraction with the smallest inhibition zone was found at concentration of at least 8 % and 10 % respectivelly.TLC examination results of hexan fraction showed a purple spot with Rf value of 0.9 and a dark blue spot with Rf value of 0.36. Based on Rf values and color reference, the first spot was suggested zingiberen and the second spot was gingerol. All fractions that were examined, did not show any inhibitory activity against thegrowth of E coli. Thus the extract of fresh ginger was only to be used to control the respiratory disease causedby M. gallisepticum but not coli.

Abstract

Pseudomonas fluorescens has been well known as biological control agent for plant diseases control. The ;:>roblem to apply the agents widely in the field or in the level of farmer is limited technology of mass production Nith low cost, due to the simple technology of propagation has not been yet available. The objective of this research is to study the potency of liquid organic wastes as media for mass production of P. f/uorescens and to formulate them as bio-pesticide. The results showed that modification of coconut water to pH of 7.0 could be used as media for growing P. flourescens. The P. fluorescens also could grow well in livestock liquid waste by adding 10% meat extract. On the other hand, the liquid tofu waste and liquid compost waste became good media for growing of P. fluorescens by addition of 10°/o meat extract and 1.2S0/o sugar. Tetes tebu will be very good media for P. f/uorescens at S% final concentration and by adding of 10°/o meat extract and 2.S0/o of sugar. The P. fluorescens showed high antagonistic effect to Ralstonia solanacearum and Sclerotium rolfsii in all of modified liquid organic wastes media. Survival and antagonisctic activity of P. fluorescens in modified organic liquid wastes stored at S°C or room temperature were 12 weeks. In vivo antagonistic and plant growth promoting activity showed that P. fluorescens grown in liquid organic waste suppressed the incidence of stem rot diseases caused by Sclerotium rolfsii and increased the vigor of plant growth on watermelon. Formulation of the P. Fluorescens grown in modified coconut water gave the best performance of P. fluorescens in supppressing of plant diseases and inducing plant growth. The product of BeMOR(e) (beneficial microorganism) from the result of this research will be proposed to be patented.

Abstract

Indonesian log consumption average in 1999-2004 was about 40 million cubic meter per year. Far above the capacity of natural forest to supply wood demand which was only 6.9 million cubic meter per year and only 5 million cubic meter per year from plantation forest. Now community forest has been managed well based on commercial orientation to fullfill the needs of forest products.  Recently community forest is known as realible wood producer for furniture such as rubber wood (Hevea brasiliensis), Maesopsis (Maesopsis eminii), Jeunjing (Paraserianthes falcataria), Durian (Durio spp.), Jackfriut (Arthocarpus sp). However those woods have low appearance quality (pale colours and ununiform, texture not attractive). Thus they need some treatments to enhance their appearance, one of them by fumigation. The purpose of this researh are to gain optimalize fumigation condition (combination between amonia volume and time of fumigation) to have wood stain that resistance from weathering and to analyze durability of fumigation wood against Cryptotermes sp attack.  The treatments were fumigation by 2, 4, 6 litre of amonia for 1, 2, 3 days.  Those treatments were applied on 5 wood species (mahagony, jackfruit, rambutan, menteng and mindi). The results of this research showed that fumigation treatments have effects only on jackfruit, mahagony, rambutan. They did not have effects on menteng and mindi. Because the difference of tanin content between woods, made every wood had different reaction to fumigation (amonia). Based on comparison of all treatments quantitatively showed the most darkened colour of jackfruit was resulted by fumigation by 4 litre amonia for 3 days, mahagony was fumigation by 6 litre amonia for 2 days and rambutan was fumigation by 4 liter amonia for 2 days.  Weathering resistance resulted all wood species did not resist to weathering or their colour fade away. Wood fumigation durability showed 100 % mortality of Cryptotermes sp (on jackfruit, mahagony and menteng), on the other hand mindi showed 83 % and rambutan 89% mortality of  Cryptotermes sp.

Abstract

Marginal and degraded lands in Indonesia are considerably extensive and include many kinds of soil, for instance acid soil and post mining soil. Efforts to overcome the problem of acid soils and post mining soil are  the use of biological fertilizer such as arbuscular mycorrhizal fungi (FMA), phosphate dissoving microorganism (MPP), and nitrogen fixer microorganism (MPN). The objective of this research was seeking new formulation of biological fertilizer which constitute a consortium between Mycofer with MPP, MPN, and humic acid which could increase its ability for supplying nutrients and   help to increase plant survival in less favorable environment. The first year research comprised the following research stages: (i),  Preparation of augmentation materials, namely multipilication of potential microbe (FMA, MPP and MPN) and humic acid ; (ii)  Formulation of biological fertilizer which constitute the consortium of Mycofer with MPP, MPN and humic acid. There were 6 formulas of biological fertlizer which were tested in this research, namely (a) Mycofer with addition of MPP isolates 1, 2 dan 3; (b) Mycofer with addition of Azospirilum isolates 1, 2 and 3; (c) Mycofer with addition of Rhizobium isolates 1, 2 and 3; (d) Mycofer with addition of humic acid; (e) Mycofer with addition of  MPP, Azospirilum and Rhizobium; (f) Mycofer with addition of MPP, Azospirilum, Rhizobium and humic acid; (iii) Test of  Mycofer plus formulation in post mining acid soil and latosol soil at laboratory scale with corn crop and Legum Cover Crop (LCC) which comprised (a) Centrosema pubesens (b)  Pueraria phaseoloides, and grasses which comprised (a) Panicum maximum , and (b) Setaria splendida in pots with 5 kg capacity for 3 months. In the second year research, the first factor was microbe treatment, which compriserd 4 levels, namely P1 (control), P2 (mycofer), P3 (mycofer with Azospirillum/Rhizobium) and P4 (mycoferd, Azopirillum/Rhizobium, and MPP); whereas the second factor was technological treatment which comprised 3 kinds of technolgy, namely T1 (SOP of gold mining), T2 (technology of soil amelioriation), and T3 (hydroseeding technology). Result of the first year research indicate that the five crops species tested gave different responds weather in latosol soil or in post mining soil.   In general, all plant species tested indicate that they not only need single microorganism but  need consortium of microorganism.  The plants were better growth  when inoculated with consortium of microorganism combined with humic acid both in latosol soil and post gold mining soil respectively. The second year research was conducted in post gold mining land of PT Aneka Tambang, in Pongkor, Bogor.  The results showed the tolerant crops that did not require technology and addition of microbe for their growth are Calopogonium muconoides and Setaria spendida whereas Brahiaria humidicola and Centrosema pubesescens only required treatment P3, P4 and P2. Pueraria phaseoloides and Panicum maximum were categorized as sensitive plants because they required additio of microbes and technology, namely treatments T3P3 an treatment T3P4.

Abstract

The Digitaria ciliaris, wild grass grown around rice field, was a host for Pyricularia grisea (Cooke) Sacc., the fungi caused blast disease of rice. This fungi have a specific mechanism to regenerate new genetic variation in its life cycle. The aim of this research is to study the relation between the ability of the fungi to infect different species of host with its genetic plasticity. It was used three SCAR molecular markers Cutl, Pwl 1 and Erg2. P. grisea isolates (Dc4J1) originated from D. ciliaris at Jasinga-Bogor were able to infect rice cultivars Kencana Bali and Cisokan. The original Dc4Jl, from D. ciliaris, and the Dc4Jl that were reisolated from the infected rice cultivars (reisolates-1) had the same ability to infect Kencana Bali and Cisokan. Molecular technique showed that there was a different molecular marker genotype between the original Dc4J1, from D. ciliaris, and the Dc4Jl reisolated from infected rice cultivars. The original Dc4J1 owned Cutl but did not Pwl2 in contrary the reisolates Dc4J1 from rice cultivars (reisolates-1) had Pwl2 but did not Cutl. The Erg2 presented in both the original and the reisolated Dc4Jl. These results indicated that there were a change of genotype of P. grisea at the same time with the change of host species. The Dc4Jl isolates originated from Kencana Bali and Cisokan (reisolates-2) that were infected by reisolate-1, had the same genotype with the reisolates-1.
