Abstract

The study of lake fishes community in North Sulawesi and Gorontalo provinces was done during July and August 2001. The lakes of study were Tondano (St.1), Moat (St.2), Tondok (St.3) and Limboto (St.4) under observation methods to determine the  fishes diversity, abundance, local distribution, status and economy values. There were  17 different species from 12 families screened during this study, the Cyprinidae was the dominant one  and consist of three  species. Overall  the variation of  fishes consist of eight  introducable species and nine native species. The most abundance species was Ophieleotris aporos  and the most wide distributed was Cyprinus carpio, mostly species have  economic values. Comparing to three other lakes, the Limboto has the  most various species of  fishes.

Abstract

Ular dianggap berkerabat dekat dengan kadal berdasarkan anatomi perbandingan yang memperlihatkan kemiripan struktur di antara mereka.  Beberapa ahli zoologi berasumsi bahwa moyang ular merupakan hewan sebangsa kadal yang dahulunya hidup di liang. Pola hidup di liang dengan menggali lubang di dalam tanah, membuat mereka tidak begitu memanfaatkan kedua pasang tungkainya sehingga lama-kelamaan mengalami penyusutan dan akhirnya berdegenerasi. Pada beberapa kelompok ular primitif, yaitu ular-ular yang keberadaannya di bumi lebih awal dalam perhitungan skala waktu geologi, masih dijumpai adanya sisa tungkai yang berbentuk taji di dekat kloaka, seperti pada Familia Boidae, yaitu:  ular Pyton  dan ular Boa, sedangkan gelang panggul masih terdapat pada Familia Typhlopidae (Anonim, 1988; Gibbons 1988).

Abstract

Jika kita ingin mengetahui bagaimana hubungan kekerabatan antara manusia dengan  simpanse, maka buku karangan Jonathan Marks berjudul 'What it means to be 98% Chimpanzee: Apes, People, and Their Genes" ini cukup membantu. Setelah Allan Wilson (1985) mengemukakan bahwa 98,5% material genetik simpanse sama dengan material genetik manusia, banyak orang bertanya-tanya mengapa perbedaan yang hanya 1,5% tersebut, membuat manusia dan simpanse secara fisik jauh berbeda dan terpisah menjadi spesies yang berbeda selama jutaan tahun.

Abstract

Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is the most common human enzymopathy, nearly 400 different biochemical variants of the enzyme have been described worldwide.  The heterogeneity of these abnormal hemoglobins are very extensive in some populations such as the results of malarial natural selection and the use as genetic markers for certain populations.  As in  others malarious areas in Southesat Asia, the presence of G-6-PD deficiency in most Indonesians might be prevalent. Nevertheless the frequencies and epidemiological distribution of these hereditary blood diseases among Indonesians has not been well known yet.  This study  have screened  2 059 unrelated, apparently healthy adult blood samples from 17 different populations. The present investigation had  shown that the G-6-PD deficiency was commonly found in lesser Sunda populations sampled, hold beyond Bali to the east in significant frequencies range from 5% to 13.5%.

Abstract

The present  study aims to describe vegetation composition and structure of fragmented areas in Timor Tengah Utara. The study was carried out in three locations : the small forest of Soeb Mountain (L1), the medium forest of Ainiut-Loeram (L2), and the large  forest of Lapeom-Maubesi Mountain (L3). The data were collected using the quadrates method. Each transect is 0,52 ha and thirteen plots (20x20 m) was established. The results show that the number of trees species in the large forest is the highest followed by the medium and the small forests (L3>L2>L1); The tree density in the large forest is the highest, followed by the small and the medium forests (L3>L1>L2). However the highest tree basal area was recorded in the small forest, followed by the large and the medium forests (L1>L3>L2). The species of the highest importance value (IV) at three locations are Pterocarpus indicus Willd., Gossampinus malabarica (DC.) Merr., and Schleichera oleosa (Lour.) Oken.

Abstract

Coliform contamination emerges public health case particularly by pathogenic E.coli O157 which is characterized by hemorrhagic colitis with diarrhea. In order to study the profile of coliform bacteria contamination in fresh milk that was sold by the sidewalk trader in Yogyakarta province, in this research coliform detection was done by cultivate fresh milk samples on the medium of Chromocult Coliform Agar (CCA) and enrichment cultures on the medium of Vancomycin-Trypticase Soy Broth (mVTSB). Dark-blue colonies isolated on CCA plates were then evaluated for the ability to ferment D-sorbitol on EOH medium in order to suspect pathogenic E.coli O157 colonies. The results show that coliform contamination was 1.103 - 1.107 CFU/ml, although it was not detected on all of the samples. Profile of coliform contamination in fresh milk samples consisted of Citrobacter, Enterobacter, and Klebsiella (1,0.103  - 1,2.107 CFU/ml), Shigella, Salmonella, and Yersinia (1,0.103 - 2,1.106 CFU/ml), and E.coli (1,4.104 - 2,8.104 CFU/ml). Dark-blue isolates that were suspected as pathogenic E.coli do not ferment D-sorbitol on EOH medium. Based on this result, it was concluded that it was not associated with E.coli O157.

Abstract

Intelligent is one of human quality factors that can be influenced by nutrition. Iodine is one of trace element nutrition that necessary for intelligent level. The purpose of this research was to learn the effect of seaweed as iodine source on rats learning ability. The rats were divided into four groups based on the ratio: A (without potassium iodide/KI-seaweed flour (SF) 0%), B (with KI-SF 0%), C (without KI-SF 5%) and D (without KI-SF 10%). The ratio had no significant effect on rats growth, but significant on iodine retention, neuron cell number and rats learning ability. Iodine retention value had a positive correlation with the neuron cell number. The neuron cell number of group A, B, C and D were 72.83, 89.33, 93.92 and 100.83 cells per view area, respectively. The number of neuron cells gave a significant influence on rats learning ability. Total time needed by the rats in food retrieval test for the group A, B, C and D was 57.84, 38.17, 33.39 and 20.55 seconds, respectively. The more neuron cell number, the more learning ability.

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

Perkembangan gonad, musim pemijahan dan fekunditas ikan sebelah “brill” (Colistium guntheri Hutton, 1926) di perairan Otago Selatan, New Zealand telah diamati selama satu tahun. Sampel ikan ditangkap setiap bulan menggunakan “bottom otter trawl”. Indeks gonad, tingkat kematangan gonad dan distribusi frekuensi ukuran telur digunakan untuk menentukan perkembangan gonad dan musim pemijahan. Hasil penelitian ini menunjukkan bahwa perbandingan populasi ikan “brill” jantan dan betina tidak berbeda nyata dari 1 : 1. Pada ukuran panjang tubuh yang sama, ikan betina mempunyai berat badan yang lebih besar dari pada ikan jantan. Hasil analisa histologi menunjukkan bahwa C. guntheri termasuk kelompok ikan yang mempunyai perkembangan telur secara sinkroni. Berdasarkan perubahan nilai indeks gonad dan perkembangan ovari, jenis ikan ini diketahui mengalami pematangan gonad yang sangat cepat pada akhir musim gugur (Juni), yaitu ditandai dengan peningkatan nilai indeks gonad secara drastis dan ovari didominasi oleh telur pada tingkat kematangan akhir (final maturation stage). Musim pemijahan dimulai pada akhir musim dingin (Agustus) sampai musim panas (Januari), ditandai dengan penurunan nilai indeks gonad secara nyata dan ovari didominasi oleh telur yang telah masak (mature), hidrasi (hydrated) dan paska ovulasi (postovulatory). Fekunditas (batch fecundity) ditentukan dengan menghitung semua telur yang telah masak, mencakup sekitar 34% dari total telur di dalam ovari. Pada pengamatan ini diketahui bahwa fekunditas (Y) proporsional dengan berat gonad dalam gram (Wg) dengan persamaan regresi Y = 103 [(4.34 + 20.06 (Wg)], R2 = 0.95, dan fekunditas relatif per gram berat gonad adalah 18.760+1.150 telur.
