Abstract

The aim of this study was to evaluate the concentration, progressively motile, and percent live sperm in the various regions of epididymis and ductus deferens after preservation at 4oC. Epididymis and ductus deferens were collected from 21 epididymis and ductus deferens of domesticated cat (Felis catus) by castration. One testicle of pair (control testicle) was analyzed at the day of castration, while the other testicle of the pair was stored at 4oC up to 7 days. The sperm concentration, percentage of sperm motility and live sperm were examined daily until day-7 of preservation. The sperm concentration was higher (p<0.05) in cauda epididymis (23.99x106 sperm/ml) and ductus deferens (25.42x106 sperm/ml) than caput (11.51x106 sperm/ml) and corpus epididymis (14.82x106 sperm/ml). The percentage of sperm motility and live sperm decreased (p<0.05) during preservation period. However, the percentage of motile (11.33 to 16.00 %) and live (15.05 to 20.20 %) sperm could be found in preserved epididymis and ductus deferens up to day-7. These results show that motile and live sperm can be collected from cat’s epididymis and ductus deferens up to day 7 after preservation at 4oC.

Abstract

Kajian laboratorium ini dilakukan untuk mengetahui mekanisme pengaruh negatif hujan asam terhadap makrofauna tanah. Armadillidium vulgare yang merupakan salah satu makrofauna tanah pemakan seresah (saprofag) penting di Tokyo yang digunakan dalam penelitian ini. Pengaruh makanan, pengaruh langsung dan pengaruh medium yang direndam dengan cairan asam digunakan untuk mengetahui mekanisme ini. (1). Pengaruh makanan dilakukan dengan cara merendam seresah daun aoki (Aucuba japonica) dalam air atau air yang diberi cairan H2SO4 dengan pH 6,4, dan 2. Seresah ini diberikan pada A. vulgare sebagai makanan (2) Efek langsung dilakukan dengan cara meneteskan 1 ml air atau air yang diberi cairan H2SO4 langsung ke tubuh hewan setiap dua minggu. (3) Pengaruh medium dilakukan dengan merendam medium dalam air maupun air yang diberi cairan H2SO4. Pertumbuhan dan persen hidup A. vulgare dicatat. Pertumbuhan dan persen hidup A. vulgare yang diberi makan seresah yang rendam dalam larutan asam sangat rendah. Penetesan cairan asam pada tubuh A. vulgare secara langsung tidak berpengaruh negatif terhadap pertumbuhan dan persen hidup A. vulgare. Pertumbuhan A. vulgare tidak dipengaruhi oleh medium yang direndam dalam cairan asam, tetapi persen hidupnya sedikit berkurang. Pengaruh cairan asam secara tidak langsung melalui makanan lebih penting daripada pengaruh langsung. Hal ini disebabkan tubuh A. vulgare dilindungi kutikula yang tebal. Untuk taksa yang memiliki tubuh yang lunak pengaruh langsung mungkin juga penting.

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

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

Protease is one of the leather commercial enzymes which is widely used such in food processing, medicine and leather industry. Clostridium sp T11-3 was isolated from Tiu Jeruk River in Nusa Tenggara Barat. Sequence analysis of 16S rRNA indicated that Clostridium spp T11-3 was closely related to C. bifermentans. This isolate produced maximum protease activity after 18 hours of cultivation in liquid media. Protease of Clostridium spp 11-3 displayed maximum activity at pH 5 and 60oC with casein as substrate. In the presence of 1 mM divalent ion Mg2+ the enzym activity increased to 141 %, while others ion divalent (Ca2+, Zn2+, Cu2+, Fe2+, and Co2+) inhibited protease activity.

Abstract

The study about fruiting and flowering phenologies on various tuber weights of iles-iles has not been common yet. The fact was emphasized by Lingga et al. (1989) that most biologists and agronomists are not interested in doing research about the iles-iles, so the source is not easy to get. This research was aimed to studying the fruiting and flowering phenologies on various tuber weights of Iles-iles (Amorphophallus muelleri Blume). The experiment was done at Bogor Agricultural Institute experimental field, Darmaga at 250 m sea level height, from February 2000 to August 2002. The experimental design used was Completely Randomized Block Design with six replications. The treatment consist of four level of tuber weights, A = more than 1050 g; B = more than 700-1050 g; C = more than 350-700 g; D = less than or same as 350 g. The results showed that flowering of iles-iles occur on rainy season, after high rain intensity everydays. The higher tuber weights, compared with smaller tuber weights, produce bigger percentage of flower sprout, size of flower parts, flower size and fruit amount, and also total amount of embryo per stem. On the contrary, the percentage of vegetative sprout was produced more by lighter tuber. The flowering and fruiting on iles-iles, seem influenced by the interaction between tuber weight and the growth age of tuber.

Abstract

Industrial waste-water has become a serious problem nationwide. However, one type of waste-water, i.e. tofu waste-water (whey), can be utilized as the source of nata de soya production. This present research is attempts to reveal the effect of various concentrations of inocula and green-bean extracts on nata productions from tofu waste-water. Ten combinations of treatment were applied and coded as A1 – A10. The parameters observed included physical and chemical characters of nata and nitrogen (N) contents. The results show that the increase in concentration of N and inocula will follow by the increase of water content, fiber content, plasticity, and N content of nata de soya produced. Highest thickness of nata was gained at 200 g/L concentration of green-bean extract and 100 ml/L concentration of inoculum.

Abstract

Many people in West Papua value forest for the benefits obtained from the extraction of plants and animals. Hunting and gathering of wild animals has always been and continues to be an important aspect of life in rural West Papuan communities. Even in modern days, some ethnic groups in West Papua depend almost entirely on hunting as a part of their tradition (Pattiselanno, 2003). In other words, hunting is one of the main ways of living.
