Abstract

The Effect of Concentrate Supplementation in The Ration on Performance, Carcass and Non-Carcass Weight of Javan Porcupine (Hystrix javanica F. Cuvier, 1823). This study was conducted at Small Mammal Captivity, Zoology Division, Research Center for Biology,Indonesian Institute of Sciences, Cibinong, Bogor Regency. Eight porcupines consisted of 6 females and 2 males were used to know the effect of concentrate supplementation in the ration on performance, carcass and non carcass weight of javan porcupine. Ration treatment consisted of control ration (PI) and control ration plus concentrate comersial such as koi fish pellet (PII).Four porcupines (3 female and 1 male) were given control ration (PI) and three porcupines (3 female and 1 male) were given ration PII. A completely randomized design was used in this research. Data collected were nutrient consumption, average daily gain, feed conversion, slaughter weight, weight of cascass and non-carcass. The data were analyzed by analysis of variance. The result showed supplementation of koi fish pellet in the ration didn?t significantlyinfluence (P>0.05) performance of javan porcupine, but significantly (P<0.05) increase consumption on calcium and phosphor. Weight and percentage of carcass and non-carcass of javan porcupine were not affected by ration treatment. Average of weight and percentage of porcupine?s carcass of PI were 4,505.08 g and 59.67% and those of PII were 3,957.55 g and 56.54%, while average of weight and percentage of porcupine?s non-carcass of PI were 2,979.05g and 39.46% and those of PII were 2,774.60 g and 39.64%.Keywords: Concentrate, ration, performace, carcass, non-carcass

Abstract

ABSTRACTMetabolism of Benzonitriles by Flavobacterium sp. NUB 1. Flavobacterium sp. NUB 1 was isolated from industrial waste of PT. Petrokimia Gresik. The bacterium was able to utilize benzonitrile and acetonitrile and propionitril as the sole source of carbon and nitrogen. Growth on benzonitrile gave higher growth rate and biomass yield than growth on acetonitrile and propionitrile. When Flavovobacterium sp. NUB1 grew on benzonitril 15 mM , the doubling time is 9 hours 54 minutes and the specific growth rate (?) was 0,07 h-1. Whole cell of Flavobacterium sp. NUB 1 could hydrolyzed aromatic and aliphatic nitriles. The bacteria isolate has ability in metabolism of acetonitrile greater than benzonitrile. Activity of nitrile hydratase and amidase are more dominant than nitrilase in metabolism of benzonitrile.Key words: Biodegradation, benzonitril, Flavobacterium sp.

Abstract

Artemisia annua L. is known as one of the plants producing artemisinin, i.e. active compound that is used for anti-malaria theraphy. This plant has potency to be cultivated in Indonesia through seedlings and cuttings. The objective of  this study was to compare growth and biomass allocation of plants from seedlings and cuttings. The experiment was set using  Completely Randomize Design with one factor. The factor is type of plant propagation which cutted plant derived from three different ages of mother plants (1.5, 2, and 2.5 months after planting) and seedlings as control. The result showed that growth and biomass alleviation of the cuttings plants are more rapid than the seedlings. However, the cutting plants were flowering earlier than the seedling. At three months after planted, more than 70% of the cutting plants population have flowered. It is implied that the plants from cutting will loss about 70% of its yield potency than the seedling. On the other hand, there was no significant effects of the ages of mother plants on growth and biomass of the cutted plant (p>0.05). Therefore, seedlings were more effective than cutted plant on A. annua cultivation. Keywords: artemisia annua L., biomass allocation, cuttings, growth, seedlings.

Abstract

Picrate paper test kit for the semiâ??quantitative determination of cyanogenic potential was developed in thisexperiment. The method is relatively simple, easy to use and might be applicable in the field by unskilled person.Paper test was attached on tubes containing sample (100 mg) in aquadest (0,5 mL) and then was immediatelycovered tightly and incubated overnight at room temperature. The colour of picrate paper test changed graduallytowards reddish brown, and its colour was compared with standart colour chart which included 0-800 ppm cyanidethat was also developed in this study. The reddish brown colour of paper test was correlated with cyanideconcentration on the sample. In order to obtain a more accurate detection of cyanogenic compound the paper testwas eluted with 5 mL water or aquadest and the absorbance was measured at 510 nm.Keywords: cyanogenic potential, picrate paper test, semi-quantitative method, simple method, cassava (Manihotesculenta Cranz)

Abstract

Hubungan antra Perbedaan Tutupan Vegetasi Riparian pada Kondisi Air mengalir di kawasan Cikapinis, Jawa Barat. Vegetasi memiliki peran sangat penting di kawasan perairan yang mengalir; banyak hubungan antara tutupan vegetasi dengan aliran air dan struktur makroinvertebrata yang menghuninya. Oleh sebab itu penelitian dirancang di kawasan aliranCikapinis Jawa barat dengan mengambil contoh stasion penelitian yang terbagi menjadi tiga lokasi yaitu di hulu, tengah dan hilir. Kawasan tengah merupakan kawasan yang terbuka karena kebakaran 8 bulan sebelum penelitian. Kawasan hulu merupakan kawasan dengan kondisi banyak tertutup oleh tumbuhan perdu yang agak berbeda dengan kondisi kawasan hilir dan diikuti dengan kawasan tengah. Di kawasan tebangan, kandungan kimia air yaitu nitrat dan orthophosphat meningkat dan diikuti penurunan indeks diversitas makroinvertebrata, rendahnya kelimpahan teristimewa terjadi pada alga larva Petrophila sp. Analisis Komponen (PCA) yangdigunakan pada penelitian ini mengindikasikan adanya pengaruh antara vegetasi riparian dan kondisi fisik kimia air. Keeratan hubungan terlihat antara rendahnya tutupan vegetasi, tingginya suhu udara, intensitas sinar, kondisi tanah, nitrat, dan orthophosphat.Kata kunci: Vegetasi riparian, Aliran air, Kondisis fisik kimia, Makroinvertebrata, logging.

Abstract

The Effect of Anorganic- Iron Supplementation on The Blood Cell of Humpback Grouper Fish (Cromileptes altivelis ) Infected by Kbrio parahaemolyticus This experiment was conducted to find the immunity response of humpback grouper (Chromileptes altivelis) correlated to the anorganic-iron supplement in feed. The blood cell was analyzed as the infection response of F5brioparahaemolyticus. The fish weight 6.9 5 0.22 g/ind. was cultured in 60x40~50cm aquarium and stocked at density 10 ind. / aquarium. After the fish fed by inorganic-iron supplementation at 0,25,50 and 100 mg/ kg for 68 days, then infected by J! parahaemolyticus. The blood cell showed the 50 and 100 mg Felkg inorganic-iron supplement enhanced erythrocytes, hematocrite, hemoglobin, lymphocytes and neutrophil after the 24hand the 72ndh our's infection. Total leucocytes backed to normal after the 7Pd infection and the index of phagocytic was higher with the 100 mg Fe/kg of iron supplementation. 1 Key words: iron (Fe), humpback grouper, feed, bacteria and blood cell.
