Abstract

ANITA HANNA ATMOWIDJOJO. 1985. Resistancy of some tea (Camellia sinensis L.) clones to scarlet mites (Brevipalpus phoenicis Geijsk). Berita Biologi 3 (1) : 1-4. Scarlet mite (Brevipalpus phoenicis Geijsk) is an important pest of tea culture in Indonesia. Several means can be used to control this pest such as the use of pesticides, biological control, and the use of tea resistant clones.The last mentioned method is considered to be the best and the most effective.Most of the tea estates in Indonesia nowadays use clones as new planting materials and their resistance to scarlet mite is known to vary.In the present study, sixteen clones were compared for their resistance.The results showed that clones PS 324 and TRI 2024 were the most resistant to scarlet mite nfestations.

Abstract

Polynesian arrowroot (Tacca leontopetaloides), taka, is one of the tuberous plants that distributed near the sea shore to 220 m above sea level. Taka produces two kind of tubers, parent tuber and peripheral tuber. Local people in several locations used taka for forages, cakes, cosmetics and woven. This plant is a minor crop comodity in Indonesia, so it is not widely cultivated yet, and no informations about taka propagation method and its cultivation. Taka produces both tuber and seed for regeneration propose. Aim of this study was to investigate vegetative propagation of taka and its growth pattern. Results showed that propagation by parent tuber required 24 weeks after sowing to produce new peripheral tuber. Material propagation from new peripheral tuber will become new plant. This new plant will produce next generation tuber in 5 months later. Propagation by peripheral tuber (from field exploration) required 24 -28 weeks after sowing to produce next generation plant with leaves and flower stalk directly. Stolon and the next generation tuber were also produced. Taka tuber can be harvested when its leaf turned yellowish.

Abstract

SAEFUDIN & R. SANTOSA.1986.The effect of nitrogen, phosphorous and potassium fertilizers on the growth of Ipomoea aquatica Forst. Berita Biologi 3 (5): 214-218.Experiments to study the effect of nitrogen, phosphorous and potassium fertilizers on the growth of Ipomoea aquatica, a leafy vegetable, were carried out on four sites, i.e. in the villages of Teluk, Karangklesem, Purwokerto Kulon and Sumampir of the district of Banyumas respectively. The rates of application used were 0, 125, 250 and 375 kg of urea, triple superphosphate or potassium chloride per ha. The nitrogen fertilizer increased significantly the growth of Ipomoea aquatica with optimum rate 250 kg of urea per ha. Potassium chloride increased slightly the stem elongation, but not the vegetable yield, while the phosphorous fertilizer did not show any significant effect.Among sites, the highest yield was obtained from the plot in the village of Teluk, followed by Karangklesem, Purwokerto Kulon and Sumampir in decreasing order.

Abstract

Because the flowers of grassos are so reduced, botanists in past have relied mostly on vegetative characters, such as the spikelets and their disposition in the inflorescence,to classify the family.Hackel,in his treatment of the Gramineae in Die Naturlichen pflanzen familien (late 1800'S proposed 12 tribes based on these characteristies and regarded the tribe.

Abstract

Chinese hamsters ovary (CHO) and its derivative such as CHO-DXB11 cells, CHO-K1, CHO-DG44 and CHO-S are mammalian cells that are often used for production of therapeutic protein drugs. The CHO cells often used for protein production have several advantages including 1) host cells that are safe to use in drug production, 2) the level of production of proteins produced can be increased by amplifying genes using methotrexate (MTX), 3) having the capacity to make post-translation modificationsand 4) CHO cells can be adapted to grow in suspension. The high need for protein-based drugs triggers the development of basic knowledge and innovation in production of recombinant proteins. The impressive technological advances in CHO cell technology have made these cells can be used to produce proteins around 10 g/liter in order to meet the market demand. The first protein successfully produced using CHO mammalian cells was the therapeutic Tissue Plasminogen Activator (r-tPA, Activase) protein used for stroke patients. The presence of this drug is quickly followed by several other types of drugs. In this review, history of development of CHO cells, the contribution of CHO cells to basic research, progress of effective line cell screening and development technology are discussed.

RISTIYANTI M.MARWOTO. 1987.Some fresh water mussels family L'nionidae and gastropods from Rengas and Sungkai Rivers in Jambi province. Berita Biologi 3(7): 306 -309.Four species of unionids were found in Rengas river; of these Pseudodon vondenbuschianus,Contradens ascia dimotus,Ctenodesma sp.and Rectidens gracilis,while Physunio superbus and C. ascia dimotus were found in Sungkai river.The density of p.superbus was higher than the other species (7 ind/0.09 m ),it seems was affected by the organic detritus and the differences of the substratum sediment.Some of P.superbus were mature with many eggs and glochidia larvae inside the outer gills.The length of this mature mussels is 28 - 56 mm, while the average is 52 mm.The difficulties in finding young Union idae may be due to their size is relatively small it was or caused by the specific biology of these animals.The occurance of some gastropods in Rengas and Sungkai river were also discussed.

Abstract

Untuk mengadakan persilangan tanaman perlu diketahui terlebih dulu sifat perbungaan kedua tanaman yang disilangkan. Bila tidak diketahui saat masak dan suburnya masing-masing bunga yang di silangkan secara pasti, usaha persilangan dapat gagal, Kegagalan ini disebabkan antara lain oleh masak bunga pada kedua tanaman yang disilangkan terjadi pada waktu yang berlainan dan kurun subur bunga nya sangat pendek.Lain halnya bila sifat perbungaan kedua tanaman tersebut sudah diketahui sebelumnya.Masalah yang disebabkan oleh masak bunga yang berlainan dan kurun subur bunga yang pendek dapat diatasi dengan cara mengatur waktu persilangan yang tepat.

Abstract

D.I. HARTOTO. 1986. Local and spatial distribution of Puntius binotatus and Rasbora lateristriata in Ci Taman Jaya and Ci Binua, Ujung Kulon. Berita Biologi 3(6): 261 - 267. A study of local and spatial distribution of the "beunteur" (Puntius binotatus) and the "paray" (Rasbora lateristriata) on two streams at the vicinity of Ujung Kulon National Park was conducted during dry (August 1983) and rainy season (January 1984).This study as a part of a sets of autecological studies, was aimed to reveal the differences of local and spatial distribution pattern of the two species. The results indicated that the pattern of distribution of paray were not significantly differed from beunteur, however, it was clearly shown that there are certain centers of local distribution for each species. It was also shown that the upstream segments were dominated by the beunteur and the downstream/segments by the paray. Observation on the spatial .distribution yield that the beunteur dominated the calm water habitat resources and paray occupied the rapidly moving water habitat resources.The possibilities of control mechanism of each pattern of distribution from time. to time;including inter and intraspecific competition, substrate preferences and others; were briefly discussed.

Abstract

Waduk Selorejo yang terletak pada lintang 7° 53' LS dan 112° 21' BT dan luasnya 400 hektar, telah selesai dibangun pada tahun 1970.Waduk ini terbentuk karena terbendungnya aliran Kali Konto dan Sungai Kwayangan. Pada tahun 1973 waduk Selorejo secara tidak disengaja telah dimasuki ikan mujair (Sarotherodon mossambicus (Peters). Dominansi ikan mujair yang tertangkap, oleh Suwignyo (1973) dikatakan sebagai pencerminan meningkatnya populasi ikan tersebut.Fihak pengelola Waduk Selorejo telah melakukan penangkapan ikan dengan jaring insang secara berkala pada setiap malam minggu atau malam hari libur.Jenis usaha perikanan yang diusahakan penduduk adalah perikanan pancing.Terdapat juga penggunaan jala dan jaring tetapi jumlahnya tidak banyak karena kegiatan ini dilarang dilakukan di Waduk Selorejo.

JANITA AZIZ & M. AMIR. 1988.Some ectoparasites collecting methods of racing pigeon (Columba livia Gmelin). Berita Biologi 3(8):382 - 385.Extraction of ectoparasites of living racing pigeons was done using modified "Fait Isle".The insectisides used for the extraction were pyrethrum,caumaphos and chloroform.The number of acarines extracted during the night was higher than that during the day.In addition insecticides spraying treatment extracted more acarines than fumigation.From the 3 kinds of insecticides used,chloroform proved to kill more acarines than the other two insecticides.
