Abstract

A seven week study of the Ujung Kulon National Park, West Java, Indonesia was conducted between July 29 and 17 September 1990. The purpose of the study was to compile an inventory of the reptile and amphibian species present in the National Park. 14 Anura, 16 Lacertilia, 17 Ophidian, 2 Testudinta and one Crocodile species were identified. Two Lacertilia, one Testudinata and 10 Ophidiasprecies are new record for the park. A tentative comparison was made between our result and a study of the region by Martens (1957) in 1955 and 1956. Management suggestion for the conservation of herpetofauna of Ujung Kulon National Park are discussed along with suggestion for further research.

Abstract

The research aimed to discover the response of the fast growing tree legume to Rhizobium inoculation in relation to the population density of soil Rhizobium (indigenous rhizobia). The density of soil Rhizobium bacteria was predicted based on a plant infection test by using the most probable number (MPN) of soil bacteria. The experimental design used in this work was Completely Randomized Design with factorial provided and 4 replicates. The first factor of treatment were inoculation and uninoculation, and the second factor was soil taken from 5 locations in Cigaru and Jampang-Sukabumi villages. The response of the plant was marked by the increase of dry weigh of leaf, root, and number of root nodules. The result of this study showed that the plants planted in the soil media with < bacteria/gram soil showed more response to inoculation than plants planted in soil media with > 40 bacteria/gram soil.

Abstract

Preparing some media for Drosophilla in Indonesia both for research and education is still facing a big problem. Importing them from some advanced countries needs a big money, spare time, and great effort. Besides, the medium arrival in Indonesia is not always on time scheduled. Naturally, the food for Drosophilla is the fruits which have fragrant smell and sweet. The problem is that the fruit becomes damaged and covered with mold in a very short time, i.e. 5-7 days while the life cycle of Drosophilla takes 10-12 days. The natural media can be made durable if they are supplemented with some preservative. But, the new trouble arises, that is the lack of preventives availabilities. This study aims at preparing some single media naturally which are easily gained, cheap, natural (without preservative) but durable. The method of preparation is very simple. That is, take one ripe fruit, grinderred it, then put it into the bottle. That is meant by the natural single medium. The research result are as follows: (1) the pineapple (medium) lats 43-46 days; (2) black rise “tape� (fermented food) 31-33 days; (3) white rise “tape� 29-31 days; (4) white cassava “tape� 28-30 days and yellow cassava “tape� 20-25 days. It can be concluded that the pineapple medium and the naturally fermented media are durable.

Abstract

The research was conducted to evaluate the effect of amphetamine as pshycostimulan drug on ultrastructure spermatogenic cells of male rats (Rattus norvegicus L.). Ultrastructure spermatogenic cells described from six male rats of Wistar strain. They were divided in to 2 groups (control and treatment group). Four mg/kg/days amphetamine were given sub-cutaninjection. In control to injection with physiologic saline. The last of the treatment the rat were killed after 100 days the amphetamine injection. The testis were released into fixative solution. Ultrastructure morphologic analysis of the testis were evaluate of quantitative to assess the effect of amphetamine on spermatogenic cells. Observation of spermatogenic cells (Spermatogonia, Spermatocyte, and Spermatyd cells) were done under the electrone microscope. The result of this experiment showed different morphologically from the amphetamine- treated group and their respective control. In the treatment groups, Spermatogonia, Spermtocyte, and spermayd cells less endoplasmic reticulum than normal spermatogenic cells (control). More vacuolization in membrane line of Spermatogoium cells and in cytoplasm of Spermatocyte, and Spermatic cells than normal spermatogenic cells (control).

Abstract

Timorensis deer (Cervus timorensis) is one of Indonesian natural resources that has economic and aesthetic values. They are widely distributed from Java island to eastern part of Indonesia. Although the deer is protected by law, however interest in rearing by local people is increasing, such as Timor island. Some people has introduced the deer from the vicinity islands in which from the taxonomical point of view could be a separate sub species. There is no data available on the morphological parameters on this deer in Indonesia, nor about the physiological and health status. The present study was aimed to observed the morphological and physiological parameters and its health status of the timorensis deer under captivity. The result showed that at least there is one sub-species which has introduced to Timor island. Mean of the height was less than 70 cm. Mean chewing rate during rumination was 61/minute with the rate of breathing was 24/minute. Rectal temperature was 37.7oC. Internal parasite was considered negligible.

Abstract

Sugar cane limitation was found in refined sugar production, so it needed other alternative in sugar production with various cassava. Taro, sweet potato and cassava as high carbohydtrate of various cassava can be used in liquid sugar production by using microbial enzyme. Amiloglucosidase Mucorjavanicus can degrade various cassava carbohydrate. To know liquid sugar quality of various cassava, the use of amyloglucosidase Mucorjavanius in liquid sugar production with various cassava were researched. Observation were conducted with six treatments of amyloglucosidase concentration, that is 0.00% (control); 0.05%; 0.10%; 0.15%; 0.20% and 0.25%. the liquid sugar quality was detected by measuring reduction sugar (“DNS� method), water content (AOAC), pH, colour, and amyloglucosidase activity (“Samogeny� titration method). Statistical analysis used Complete Randomized Design. The result showed that the highest reduction sugar and amyloglucosidase activity on each sugar were found on liquid sugar 0.20% enzyme (p<0.05). the highest reduction sugar and amyloglucosidase activity, was respectively on Taro 323 mg/100ml and 54.91 unit/100 ml; sweet potato 242 mg/100 ml and 47.72 unit/100 ml; and cassava 188 mg/100 ml and 41.09 unit/100 ml. the lowest total solid or the highest water content between three sugars was on taro liquid sugar 0.20% enzyme, that is 64.97% and 35.03% respectively (p<0.05). pH liquid sugar onthree various cassava was on range between 5.78-6.01. the best colour was on taro liquid sugar, that is brown to yellow. From three sugars with different raw material, the best sugar quality was tari liquid sugar with 0.20%.
