Abstract

Organ reproduksi jantan yang berperan dalam reproduksi adalah testis. Struktur histologi pada organ reproduksi dapat menggambarkan karakterisasi dari suatu spesies. Penelitian ini menggunakan organ reproduksi jantan guna menentukan karakterisasi spesies Nycticebus coucang yang tersebar di kepulauan Sumatra dan sekitarnya. Material reproduksi yang digunakan adalah testis, bakulum dan sperma melalui sediaan histologi. Hasil penelitian menunjukkan dari sediaan histologi testis diperoleh gambaran umum komposisi dari tubulus konturtus seminiferus diantaranya sel-sel spermatogenik yaitu spermatogonium, spermatosit primer, spermatosit sekunder, spermatid, dan spermatozoa. Ukuran panjang bakulum N. coucang dari ujung posterior ke ujung anterior 16,68 mm dan lebar dari lateral kiri ke kanan 3,45 mm serta panjang kepala sperma berkisar 1,2-1,6

Abstract

The objective of this study was to observe the daily behavior of Timor deer (Cervus timorensis). The study was conducted in Aertembaga village, Bitung-North Sulawesi for 30 days. Deer were kept out in the conventional coconut plantations under extensive care system.  Seven Timor deers were used in this study. The daily behavior were observed for their activities; as grazing, ruminating, lying, urinating, defecating, vocalizing, working and other activities. A time sampling method was used to record the behavior activities and observations were repeated in five time.  The respective percentage of daily activities of Timor deer for grazing, ruminating, lying, working, standing,   defecating,  urinating,  approaching  and other activities were 31.17; 14.63; 13.54; 6.23; 7.55; 8.51; 3.96; 7.915 and 6.48%.

Abstract

Genetic Diversity of Sambar Deer (Rusa unicolor) in Utilization and Implications for Conservation. The deer sambar (Rusa unicolor) is one of species of Genus Rusa, was widely distributed in South Asia antil South East Asia. This species in Indonesia was widely distributed in Kalimantan and Sumatra island, but now, the hunting, poaching and habitat loss have reduced its populations drasstically. In order to provide useful information for its conservations. The genetic diversity and population structure of the wild sambar deer was observed by analyzing the 962 bp long of fragment mitochondrial DNA (mtDNA) control region (D-loop)fragment. The result detected, twenty different haplotypes from 22 samples from Borneo and Sumatra. Overall, sambar deer have a relatively high genetic diversity compared to other the ceervid species, with a haplotype diversity (h) 0.9870 and nucleotide diversity (ð) 2.931±0.260%.The genetic distance of Borneo populations (East Borneo) higher compared with Sumatra’s populations that is d = 0.018±0.003 on Borneo and d = 0.009±0.002 on Sumatra. The structure of phylogenetic tree showed that two populations were separate based on the haplotypes differences.Keywords: conservation, control region, genetic diversity, sambar deer.

Abstract

Slow lories is small size primates of the genus Nycticebus that are in endangered status. Habitat pressure andhigh trade as pet animals has made the population decline both quantitatively and qualitatively, therefore it isnecessary to save the slow lories through conservation action. Morphologically, the individuals are difficult tobe distinguished among the species, therefore making much harder in identification for conservation purposessuch as from confiscated individuals. Therefore molecular marker is needed through mitochondrial DNA usingCOI gene sequences analysis is needed for identification. This study used 24 samples of slow lories consistedof 2 from Kalimantan, 9 from Java and 13 from Sumatra. The result indicated that in the 660 bp there were 62variable sites with 15 haplotypes: 4 haplotypes of N. javanicus, 9 haplotypes N. coucang, and 2 haplotypes N.menagensis. Base on nucleotide variations at specific sites, it was formed haplotype differences among species.The average genetic distance between species showed that Kalimanatan population were closer to thepopulation of Sumatra (d= 0.042 ± 0.006) compared with Java population (d= 0.059 ± 0.009), whereas thegenetic distance within population showed the population of Java had low diversity (d= 0.002) with a meannucleotide differences 2.6. Thus Jawan slow loris (N. javanicus) should be conserved.Keywords: Nycticebus spp., molecular, COI, conservation, marker

ABSTRACTFeeds and habitat utilization of Slow Loris (Nycicebus coucang) and Tarsier (Tarsiusbnncartus) in Pasir Panjang Forest, Central Kalimantan. This research was conducted inthe production forest of Saka and Padang Babuluh in Pangkalan Bun. Study sites werelocated at 9-42 m above sea level. Data being collected were the type of feed, nest sites andhabitat utilization. During the observation, 44 plants species from 17 families were identifiedbeing consumed and nest site by the slow lories. Twenty one species from 17 families wereidentified being habitat by the tarsier. Nest were built on growing trees and litters were usedas bedding.Keywords : Nycticebus coucang, Tarsius bancanus, feeds, habitat, Pasir Panjang Forest

Abstract

ABSTRACTGenetic Diversity of Slow loris (Nycticebus coucang) based on Mitochondrial 12S rRNA gene. The research on genetic diversity of slow loris Nycticebus coucang (kukang) was carried out. The samples are 12 individuals from three locations (Sumedang and Jember in Java, and Lampung in Sumatera). Total DNA was extracted from blood and tissue. The mitochondrial 12S rRNA nucleotide sequences were determined to investigate genetic diversity of this species. This region was amplified by using L1091 and H 1478 primers by PCR. As a result of the analysis for 386 bp nucleotide sequence, five haplotypes were found, two from Java and three from Sumatra, respectively.Key words : Slow lories, Nycticebus coucang, genetic diversity, 12S rRNA mtDNA

Abstract

ABSTRACTFeed Intake and Efficiency of Slow Loris (Nycticebus coucang) in Captivity. Study on feed intake and efficiency of captive slow loris (Nycticebus coucang) has been conducted at the Division of Zoolgy, Research Center for Biology – LIPI for five weeks. Three individuals were placed in three cages, with its sizes of 1.2 x 1.7 x 1.9 m (one cage) and 0.8 x 1.7 x 1.9 m (two cages). Feeds consisting of papaya, banana, coconut, passion fruit, guava, sweet corn, quail egg, and white bread, were given ad libitum. Average body weight of slow loris in the beginning of the study was 587 gram/head and at the end was 648.33 gram/head. Average of feed consumption was 317.26 gram/kgBW/day. Average of feed efficiency and protein efficiency ratio (PER) was 0.0270 and 0.0945, respectively.Key words: Feed, slow loris, Nycticebus coucang, captivity, feed efficiency, PER.

Abstract

The need of medicine product are increasing now. The fermentation of rice by using Monascus purpureus produce lovastatin, pigments and citrinin as secondary metabolites. The aim of this study was to know the concentration of lovastatin, red and yellow pigments and citrinin in rice which fermented by Monascus purpureus that had been mutated by using ultraviolet irradiation.Three strains were used in this research, such as AsK, yellow Jmba and red Jmba.The result were analyzed by using HPLC and Spectrofotometer. The result showed that the yellow Jmba strain which treated by UV mutagenesis for 3 minutes contain higher lovastatin (1.798%) and pigment and lower citrinin (0.019%) compare to without mutagenesis. On the other hand ASK strain produced higher lovastatin (1.903%) but higher citrinin (1.270%).This research is expected to provide scientific information to the public. That M. purpureus contained lovastatin that is beneficial, red and yellow pigments for natural food colorant.
