Abstract

Patikan kerbau (Eupobia hirta L.) contains some anti-diarrheal compounds or containanti-bacterial substances which are alkaloids, flavonoids and tannins. This study aims to determine theeffect of extract of patikan kerbau on the growth of bacteria causing diarrhea (E.coli). This researchtests phytochemical properties and examines inhibition zone (hallow zone). The design used wasCompletely Randomized Design (CRD) with six treatment of patikan kerbau extract (0 ppm, 1500 ppm,1750 ppm, 2000 ppm, 2250 ppm and 2500 ppm) and four replications. Data were analyzed by usingANOVA and if there is a significant difference, the test will be followed by a DNMRT test at 5%significance level. Phytochemical test was based on the formed color intensity. The results showedthat - average inhibition zone diameter on treatment 2500 ppm with a diameter of 10.75 mm was notsignificantly different from 2250 ppm treatment with diameter of 9.75 mm. However, it wassignificantly different with treatments of 2000 ppm, 1750 ppm, 1500 ppm and control. The controlgroup (0 ppm) with a diameter of 6 mm (no inhibition zone formed) was significantly different fromother treatments. Phytochemical test showed that the active compound contained in patikan kerbauare alkaloids, flavonoids and tannins. These compounds have anti-bacterial property and can be usedas an anti-bacteria.

Abstract

Insects, including termites, ants, and beetles are taxonomically diverse, abundant, andecologically important in the soil environment. Although not too diverse, earthworms are also abundantin the soil. The objective of this study was to determine the effect of land use (LU) change on diversityand abundance of soil insects and earthworms in Sumberjaya, Lampung. Methods used were monolith(for earthworms), transect (for termites), and Winkler (for ants and beetles). Termites and earthwormswere identified up to species, ants up to generic level, and beetles to family/sub-family level. Resultsshow that from seven land use types (less disturbed forest, more disturbed forest, polyculture coffee,monoculture coffee, food crop, vegetable crop, and shrub) we found 53 ant genera, 59 beetle families/ subfamilies, 37 termite species, and 10 earthworm species. Diversity and abundance of ants,beetles, and termites decrease as LU intensity increases. LU change did not affect earthwormdiversity or abundance, but smaller-sized earthworms tended to be found in more intensive LU types.Deforestation caused the loss of native earthworm species.

Abstract

The aim of this study to was to observe the impact of raising the pH of red-yellow soil byadding ashes and its relation to nitrogen fixer microorganisms activities. This experiment wasconducted using completely randomized design. The treatment is ash level i.e A = 0 g (control), B =20 g, C = 30 g, D = 40g, E = 50g, and F = 60g in 5 Kg of soil. The experiment was tested onsoybean (Glycine max (L.) Merr.). Measurement included soil pH both before and after treatment andthe number and biomass of nodules. The results of the study show that ashes significantly increasesoil pH (between 1,39 and 1,74 point) and significantlt affect on the number and biomass ofnodules. The highest number of nodules was found on treatment C and D, whereas the highestbiomass was on C and E. The optimal ash concentration to increases red-yellow podsolik soil pH andformation of nodule in Soybean is 30 to 50 g in 5 Kg soil.

Abstract

This paper presents the preliminary finding on road kill survey by direct observations onthe high ways. The road-kills recorded of small wildlife, including medium size-mammal (2.50%, n =1), birds (5.00%, n = 2) and small mammals (92.50%, n = 37). The small mammals include the mostcommon mammals in the areas, squirrels, raccoons, skunks and woodchuck. Of mammals, squirrels(35.00%) were the highest recorded, followed by woodchucks (25.00%), mice/shrew (17.50%),raccoons (10.00%), skunk (5.00%) and domestic cat (2.50%) respectively. It seems road-kill wascaused by conflict between the wildlife natural habitat as well as its ecological behavior and roaddevelopment.

Abstract

Pasak Bumi (Eurycoma longifolia Jack) have potency to be used to increase bodyendurance, to cure malaria drug, and to act as afrodisiak. However, the effect of pasak bumi onwomen fertility, especially at pre-copulation stage was not widely known. This research seeks toreveal the effect pasak bumi extract treated at pre-copulation phase on fertility. This experimentemploy mice (Mus Musculus L.) and was undertaken at Biology and Cemistry laboratories PMIPA, andVeterinary laboratory of Jambi University, from November 2008 until January 2009. We used acompletely randomized design with four treatments and 6 replications: The treatments were K: controlwithout extract, E200 (200 mg/kg BW/day), E400 (400 mg/kg BW/day), and E600 (600 mg/kg BW/day).The extract is goven orraly within 10 succesive days of pre-copulation phase. We performed surgeryon the mice on 18th date of pregnancy. Observation parameters were focused on body weight, totalimplantations, and foetus percentage. The results show that Pasak bumi root extract treatment at precopulationstage does not affect total implantation declining, fetus weight, and mice body weight.However, the treatment significantly effect percenatege of lived fetus, and ovary weight.

Abstract

Transformasi genetik tanaman menggunakan Agrobacterium tumefaciens yang membawagen CP (coat protein) telah dilakukan untuk memperoleh tanamn transgenik tahan Peanut Stripe Virus(PStV). Penelitian ini bertujuan untuk mengevaluasi (1) transformasi genetik (proses rekayasagenetika) tanaman dan (2) ketahanan tanaman transgenik model (Nicotiana benthamiana) generasi T0yang membawa gen CP dan gen GUS/NPTII terhadap infeksi PStV. Hasil penelitian menunjukkanbahwa masa kritis untuk regenerasi tanaman transgenik hasil kultur jaringan adalah tahapanaklimatisasi. Tanaman transgenik N. benthamiana yang pertumbuhannya baik dengan batang lebihbesar, akar dan daun yang banyak dalam kultur in vitro, biasanya akan lebih berhasil diaklimatisasi.N. benthamiana transgenik yang membawa berbagai tipe gen CP-1, CP-2, CP-3, CP-4, dan genNPTII/GUS telah dapat dihasilkan. Sedangkan ketahanan tanaman transgenik terhadap PStV terjadiakibat integrasi gen CP dan bukan karena integrasi gen marker atau karena proses-proses lain yangdilalui dalam kegiatan transformasi tanaman dengan bantuan Agrobacterium.

Abstract

We undertook a research about the role of cinnamon agroforest in conserving bird inKerinci Seblat National Park. To observe the bird we used method of Indice Poctuale De'Abundance,whereas for the bird identification we employed some methods developed by Mckinnon ( 2001) andKing and Dickison (1993). As a control we also carried out the similar observation in the closed byprimary and secondary forest. The result shows that the bird diversity in cinnamon agroforest is notsignificant compare to that in primary and secondary forest (p>0.05). The index of bird diversity ( H') incinnamon agroforest and secondary forest is in medium class (3.3 and 3.49) while in the primary forestthe index is high (3.50).
