Abstract

Bird species can be identified using bird’s sound. Research about sound bird identification is lacking in Indonesia. This research is initial study to classify bird based on sound and its spectrum. The research was done in Laboratory of Animal Anatomy to record bird sample sound and Laboratory of Computation Physics for data analysis. This research used five recorded sound birds, i.e. Blue-Crowned (Loriculus galgulus), Greater Green (Chloropsis sonnerati), Black-Crested (Pycnonotus melanicterus), Long-Tailed (Lanius schach), and Asian Pied Starling (Sturnus contra). Identification of bird sound spectrum has been done using Fast Fourier Transform (FFT) method. Bird sounds and spectral that plotted in time-domain and in frequency-domain, were indicated unique pattern lead to bird identification method. The result showed that five birds recorded had different sound characteristics, both in time domain and sound spectrum frequency domain. The sound spectrum identification method can be used as initial step toward bird species classification called sono-taxonomy.

Abstract

Earthworm is one of the soil macrofauna, which consumes organic matter for body growth and life. Therefore the earthworm can be soil organic status and soil fertility indicator. On the other hand, at present, the organic farming system is developing and positively accepted by people as yield consumer, and yield price is higher than conventional yield price. The experimen to study the earthworm population rate and spread methode was conducted in 2008 planting season, in West Java, with RBD (Randomized Block Design). Three farming system as treatment i.e Organic farming, Semi organic and Conventional farming system and six location as replication. The result showed that Semi organic farming system is the most earthworm population rate and the earthworm distribution is random model.

Abstract

Mangrove and estuary ecosystems are important components of the intertidal area which is the habitat of Ocypodid crabs. The study of Ocypodid crabs in Ujung Kulon National Park is still limited, while its habitat is decreasing. This study was conducted to explore the Ocypodid crabs (Brachyura: Ocypodidae) composition in mangrove and estuary ecosystems in Ujung Kulon National Park. Crabs species collection was carried out in Legon Cibariang, Panaitan Island and Cikawung, Ujung Kulon National Park. Four species of Ocypodid crabs, Ocypode ceratophthalma (Pallas, 1772), Uca annulipes (H. Milne Edwards, 1837), U. coarctata (H. Milne Edwards, 1852) and U. triangularis (A. Milne Edwards, 1873) were successfully collected from mangrove and estuary ecosystems. The species composition of Ocypodidae in Cikawung were more various than in Legon Cibariang.

Abstract

Shrimp’s skin and carapace has been used as color enhancement. The shrimp’s skinand carapace was pounded into flour and added to the commercial pellet availablelocally. The shrimp’s flours contains red pigmen astaxanthine. The Koi’s used in thisexperiment were two months old Cyprinus carpio L var kohaku. Five level of differentconcentration of shrimp’s flour were used i.e. 5.7%, 8.5%, 11.4%, 14.2%, and 17.1%respectively. Each aquarium contains three fishes were used in threeplicate and rearedfor 8 weeks. Five main color or hue was observed i.e. Redish Orange, Pastel Orange,Orange Red or Yellowish Red, Red and High Red or Vivid Red. 15 panelis have beenused to give their comments to the color enhancement. The results shows that the valueof the fish’s color didn’t change much, but the chrome intensity increase on week eight.Statistical analysis of Kruskall-Wallis and Mann-Whitney Test shows that on theconcentration of shrimp flour of 11,4% was giving the best value for hue and chrome.On the consentration of 14,2% and 17,1% the results were not strong enough. This isprobably because the concentration of the flour reaches maximum at 11,4% and givingmaksimum color enhancement level so that more additioing didn’t gave any change.

Abstract

The effects of mioinositol and yeast extract were studied to assess their influence on growth of plantlets of Artemisia vulgaris by shoot culture. The plants regeneration of A. vulgaris were established by removing the nodes of stem and growing in MS multiplication medium with 1 ppm kinetin and 1 ppm NAA for 4 weeks. Shoots were induced for roots on MS treatment medium supplemented with mioinositol and yeast extract, added with 2 ppm IBA. Combination of four levels mioinositol concentration (mg/l): 100, 200, 300, and 400, and four levels of yeast extract concentration (mg/l): 0, 200, 300, and 400 were simultaneously added. Plantlets (2 weeks) were sub cultured on semi liquid MS medium. Plantlets were harvested on 6 weeks old. Measured parameters were fresh weight of plantlets. Data were analyzed using ANOVA followed by HSD test (p=95%). The results showed that the treatment of mioinositol and yeast extract were not significantly influenced on fresh weight of plantlets. Yeast extract was not influenced the growth of plantlets. The growth and morphogenesis of plantlets A. vulgaris were induced in treatment 100 ppm mioinositol, and addition mioinositol were higher than 100 ppm not significantly influenced the growth of plantlets.

Abstract

The sudy of mangrove forest in the coastal zone of Mandar Bay, Polewali, Province of South Sulawesi was carried out from  July 21st to July 28th  2002. Data was collected from 5 locations (Panampeang Island, Battuwai Island, Salamah Island, Koremasang Island, and coastal zone of Binnuang) following transect method.  The result showed that mangrove in the coastal zone of Mandar Bay was dominated by Rhizophora  stylosa and Sonneratia alba. The floristic composition of mangrove forest consist of 29 species. Recently, the extent of mangrove forest in this area was decreasing due to the conversion of mangrove into human settlement, fishpond and uncontrolled mangrove exploitation. This situation lead to the depletion of the living organisms, which are living in this area.

Abstract

In attempt to understand the diversity of Actinomycetes that is potential to be antibiotic producer, Streptomycetes were isolated and identified from soil sample taken from rhizosphere and non-rhizosphere of corn (Zea mays L.). The best antibiotic producers were identified by Scanning Electron Microscopy analysis and the identification of antibiotic produced conducted by using Thin Layer Chromatography analysis. The result of the study showed that 58 isolates were assigned to 17 colour groups. Ten isolates among the representatives of 17 colour groups were found potential to be antibiotic producer. Four isolates out of 10 isolates could inhibit both Staphylococcus aureus ATCC 25923 and Bacilus subtilis FNCC 0060, one isolate could inhibit only Staphylococcus aureus ATCC 25923 and five isolates could inhibit only Bacilus subtilis FNCC 0060. But no isolate could inhibit Escherichia coli ATCC 35218 and Salmonella typhimurium FNCC 0164. Among 10 isolates of antibiotic producer it was found that only one isolate (RNJ14) could strongly inhibit Staphylococcus aureus ATCC 25923 with inhibition zone diameter of 32.33 mm. On the bases of Thin Layer Chromatography analysis, the antibiotic produced by the isolate RNJ14 was identified to be lincomycin. Therefore it could be concluded that streptomycetes isolated from the rhizosphere and non-rhizosphere of corn (Zea mays L.) were potential to produce antibiotic.

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.

Abstract

Uji toksisitas tributiltin secara akut telah dicobakan pada kopepoda tropis Apocyclopssp. yang diisolasi dari tambak Manembo-nembo Bitung, Sulawesi Utara. Kopepodadikultur dalam kondisi laboratorium (25-27oC, 30 ppt dan tanpa penerangan) denganpemberian mikroalga Nannochloropsis oculata sebagai pakan. Semua individukopepoda yang digunakan sebagai hewan uji berasal dari sepasang induk jantan danbetina. Kopepoda untuk eksperimen tributiltin (TBT) diberi perlakuan dalam air lautdan selama eksperimen tidak diberi pakan, dan larutan stok TBT-Cl dilarutkandalam aseton. Pengaruh starvasi (tanpa pemberian pakan) dan aseton diamatisebelum uji toksisitas TBT dilakukan. Setiap eksperimen, 10 kopepoda dewasa (5jantan dan 5 betina) dari satu kohort dimasukkan ke dalam cawan petri (diameter 3cm) berisi masing-masing 10 ml air laut. Ternyata perlakuan tanpa pemberian pakantidak mempengaruhi kopepoda selama periode eksperimen. Dalam uji toksisitas TBT,hanya 3 individu yang dapat bertahan sampai akhir eksperimen (8 jam) walaupundengan konsentrasi terendah (0.0001 ng.l-1). Kebanyakan individu telah mati sebelum8 jam diekspos ke konsentrasi TBT 0.01 ng.l-1. Pada konsentrasi TBT yang lebihtinggi (0.1 dan 1 ng.l-1), tingkat kelulusan hidup kopepoda hanya 50% dalam waktukurang dari satu jam, sedangkan kopepoda yang sisa masih hidup semuanya sebelummati jam ke-4 yang diberi perlakukan. Dalam uji toksisitas ini, semua konsentrasiyang dicobakan ternyata lebih kecil dari rata-rata konsentrasi TBT di alam (10 ng.l-1).Kisaran konsentrasi TBT yang lebih lebar masih perlu diuji-cobakan untukmengklarifikasi efek akut TBT agar dapat diperoleh konsentrasi untuk uji toksisitassecara kronis.
