Abstract

The influence of fed Orange II containing medium on the growth of Enterococcus faecalis ID 6017 and its decolorization ability was studied in this research. A fed batch growth was compared with the batch growth. Total Orange II added to the both was 120 mg/L. In the fed batch, the Orange II was given into three steps. The first addition was at the initial culture medium. The second and third were added after the almost total decolorization or clearance of the Orange II given in the first or the second addition respectively. The culture was incubated under static condition and room temperature. The fed batch growth was better than the batch growth, seen from both aspects; their growth parameters and the decolorization ability. The biomass yield and specific growth rates of the fed batch was higher than the batch growth. Under fed batch growth, the decolorization was 85-94%, while the batch growth was only 54%. For achieving these performances, the fed batch growth was needed to consume more glucose.

Abstract

Eksplorasi genom manusia yang terwadahi dalam Human Genom Project (HGP) telah berhasil mengidentifikasi keseluruhan genom (DNA) manusia dalam waktu 13 tahun (1990-2003), dua tahun lebih cepat dari yang ditargetkan (15 tahun). Karya yang spektakuler ini memberikan banyak informasi tambahan mengenai genom manusia. Genom manusia yang dahulu diperkirakan berukuran tiga milyar basa, ternyata tersusun atas 2,3 milyar nukleotida yang terdiri dari ±30.000 gen, 50% gen tersebut sudah diketahui fungsinya. Kromosom no.1 mengandung gen paling banyak (2.968 gen) sedangkan kromosom Y mengandung gen paling sedikit (231 gen). Selain itu, diinformasikan pula bahwa pembeda manusia yang satu dengan yang lain terletak pada tiga juta lokasi single nucleotide polymorphisms (SNPs).

Abstract

Bagi Suku Dani, yang mendiami Lembah Balim, Pegunungan Tengah Papua; ubi jalar adalah komoditas pokok dan zero waste. Bagian pucuk tanaman ini digunakan sebagai sayur, batang dan daun tua sebagai pakan, sedangkan umbi ubi jalar sebagai pangan utama. Sistem budidaya yang dilakukan wanita Suku Dani, yakni memangkas tajuk ubi jalar sebagai sumber pangan dan pakan menjadi latar belakang penelitian dengan tujuan mempelajari pengaruh pemangkasan tajuk terhadap produksi umbi ubi jalar. Data hasil penelitian ini dapat diaplikasikan untuk menentukan waktu pemangkasan pucuk yang tepat agar kebutuhan daun muda, batang dan daun tua, serta umbi ubi jalar dapat dipenuhi secara optimal. Penelitian dilakukan di Kebun Raya Biologi Wamena pada bulan Juni-Desember 2017. Plot percobaan disusun berdasarkan Rancangan Acak Kelompok. Perlakuan terdiri dari 2 faktor yaitu kultivar (Helaleke (H), Musan (M), Wenabuge (W) dan Tabugole (T)) dan pemangkasan (tanpa pangkas, 2 bulan, dan 4 bulan). Hasilnya menunjukkan untuk budidaya ubi jalar dataran tinggi, pemangkasan pucuk batang di umur 2 bulan mengurangi ukuran tajuk tanaman, tetapi tidak mempengaruhi pertumbuhan dan produksi umbi tanaman ubi jalar. Pemangkasan pucuk batang pada umur 4 bulan tidak direkomendasikan. Produksi berat umbi lebih dipengaruhi oleh varietas daripada perlakukan pemangkasan. Kultivar Musan direkomendasikan untuk dibudidayakan dengan tujuan dipanen pucuk dan umbinya. Kultivar Tabugole masih dapat dibudidaya untuk produksi pucuk dan umbi apabila panen pucuk dilakukan paling lambat umur 2 bulan, sedangkan Kultivar Helaleke dan Wenabuge sebaiknya tidak dipangkas.

Abstract

Cyclodontostomum purvisi  (Adam, 1933) is a nematode infects small mammals belongs to family Muridae  (Rattus spp and Maxomys spp)  in  Kalimantan, Sulawesi and Java. There are some morphological variation on those nematode such as the number of corona radiata elements and head orientation (the angle between cephalic collar and sagital body axis). The angle is stronger in the specimens from Kalimantan and decreasing in the specimens in Sulawesi and Java. R. exulans  from Kalimantan and R. tanezumi from Sulawesi are the new host record for  C. purvisi in Indonesia.

Abstract

A study on the antioxidative properties of white saffron extracted with aceton, ethanol or methanol was undertaken. The purpose of this research is to have a white saffron extract with a high antioxidant activity. White saffron rhizome was peeled, washed, grated, and added within either aceton, ethanol or methanol (white saffron : solvent = 1:3 or 1:4) (W/V) then stirred for 1 hour. The residue was washed with solvent in the same volume. The antioxidant activity of the extract was measured by Ferrythiocyanate (FTC) or Thio Barbituric Acid (TBA) methods. The result showed that the antioxidant activity of white saffron extracted with ethanol was higher than that with methanol, and aceton, respectively. The highest antioxidant activity was obtained from the extract of white saffron extracted with ethanol.

Abstract

This research has an objective to study chemotaxis of osmotolerant rhizobacteria strains Al-19 dan M7b in greenpea plant. These isolates were used to inoculate greenpea plant. The study on chemotaxis of osmotolerant rhizobacteria was conducted by CFU method in order to count the number of osmotolerant rhizobacteria AL-19 dan M7b in rhizosphere. Visualization of those isolates on root surface used fluorescence microscope and agglutination reaction with exudates of greenpea root. Result of the study showed that both isolates of osmotolerant rhizobacteria Al-19 dan M7b were found in rhizosphere of greenpea with low-density. Simple carbohydrate is substrat that is essential for rhizobacteria to grow thus the chemotaxis of both rhizobacteria is considered as metabolism - dependent. It means that it is not only as digested material but also function as affinity substance. These isolates gathered on the root surface weakly and did not make glutination reaction. This condition indicated that these isolates could not form colony on root surface of greenpea.

Abstract

Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is the most common human enzymopathy, nearly 400 different biochemical variants of the enzyme have been described worldwide.  The heterogeneity of these abnormal hemoglobins are very extensive in some populations such as the results of malarial natural selection and the use as genetic markers for certain populations.  As in  others malarious areas in Southesat Asia, the presence of G-6-PD deficiency in most Indonesians might be prevalent. Nevertheless the frequencies and epidemiological distribution of these hereditary blood diseases among Indonesians has not been well known yet.  This study  have screened  2 059 unrelated, apparently healthy adult blood samples from 17 different populations. The present investigation had  shown that the G-6-PD deficiency was commonly found in lesser Sunda populations sampled, hold beyond Bali to the east in significant frequencies range from 5% to 13.5%.

Abstract

The objective of this study was to evaluate the effect of combination benzyl amino purine(BAP) and naphtalene acetid acid (NAA) on tissue culture of Chrysanthemum. Theexperiment was conducted at The Tissue Culture Laboratory, Agriculture Faculty,Stiper Agriculture Institute. The Completely Randomized Design was applied in thisexperiment, consisting of two factors; those were BAP and NAA application. Each factorconsisted of four treatments. Each combination of treatment was carried out with ninereplications. The conclusion from this study were: Application of higher BAP and NAAconcentration increased budding of explant, whereas application of higher NAA thanBAP concentration increased the growth of bud and leaf number, also increased rootingof explant.

Abstract

Phosphate removal  in domestic wastewater or  industrial wastewater is a key factor of prevent eutrophication. Mechanisms of  biological  phosphate removal occurs  under both  of anaerobic and aerobic conditions.  Phosphate up take under aerobic condition  is much determined by phosphate released under anaerobic condition. The objective of this research was  to  understand the effect of  various of  external  pH  on phosphate released  by  activated sludge  under anaerobic conditions. For that purpose, the  experiments were  conducted  in  batch system  under anaerobic condition  at  pH of  6.0, 7.0, 8.0 and 9.0   separetely. PO4, Acetate  and MLVSS  were  measured  and  used  as  parameters to  analyze  process.  The results shown  that the highest of  phosphate released  and acetate consumed occurred at pH 9.0 and the lowest it was occurred at pH 6.0. The value of   phosphate/acetate ratio was calculated to be in variation  of 0.161  to 0.256  p-mol/C-mol  in  pH  range  of 6.0  to 9.0
