Abstract

Estimation of carcass cutability is an important factor in beef marketing. This research was conducted to observe the relationship among variables of carcass cutability estimation in hot carcass of SimPO (Simmental-Peranakan Ongole) and LimPO (Limousin-Peranakan Ongole) cattle. Eighty three bulls were used, consisted of 51 SimPO and 32 LimPO cattle. The data collected were age, body weight, carcass weight (X1), fat thickness (X2), ribeye area (X3), percentage of visera fat (X4), and carcass cutability. The data were analyzed using Independent Sample T-test, correlation 2-tailed, enter and stepwise regression analysis, and estimation curve. There were no different of age, body weight, X1, X2, X3, X4, and carcass cutability among SimPO and LimPO. There was a positive correlation between X1, X2, X3, X4 and carcass cutability (P<0,05), except to LimPO which had negative correlation for X4. The regression equation and determination coefficient of SimPO and LimPO were Y=-24,726+0,916X1; R2=0,948 and Y=-28,461+0,929X1; R2=0,996, respectively. The result indicated that the best equation for SimPO was a linear equation (R2=0,948), and a quadratik equation (R2=0,996) for LimPO.

Abstract

MUSTARIM SILUBA. 1987.Species abundance Corbicula possoensis and Melanoides granifera Mollusca) in Poso Lake, Central Sulawesi.Berita Bioiogi 3(7): 317 - 320. Corbicula possoensis and Meianoideu granifera are the two dominant species among 18 species of the mollusca that occured in poso Lake.The highly abundance of these two species distributed among three habitat types, i.e. sandy. mudsand, and gTavelly habitat. The study showed that the abundance of C. possoensis is 126,66/m2 in "sandy habitat, 118,66/m2 in mudsand habitat, and 51,00/m2 in gravelly habitat respectively. The abundance of M. granifera was lower then C. possoensis, i.e. 53,00/m2 in sandy habitat, 91.00/m2 in mudsand habitat, and 51,33/m2 in gravelly habitat. It is suggested that the references is done to their preference and their feeding technique.

Abstract

Di Indonesia ada dua marga polong-polongan yang dimanfaatkan bijinya untuk makanan manusia. Kedua marga tersebut adalah Parkia dan Pithecellebium. Dari tiga Jenis Parkia yang dilaporkan tumbuh di Jawa, P. speciosa merupakan petai yang limum diperjualbelikan.Menurut Backer & Bakhuizen van den Brink (1963), petai menyilang secara alami dengan kedawung (P. roxburghiij dan bastar alaminya adalah P. intermedia.Dari segi morfologi, petai dan kedawung mud&h dibedakan, baik dari segi perawakan pohon maupun sifat-sifat polongnya.Dengan demikian adanya bastar antara kedua jenis yang berbeda sifatnya ini akan dapat dikenali dengan mudah pula.Meskipun petai sudah lama dibudidayakan dan dimanfaatkan, keanekaragaman yang ada pada petai ini belum diungkapkan.Memang benar Backer & Bakhuizen van den Brink (1963) menyebutkan bahwa dua macam P.intermedia menyerupai petai sifat-sifatnya, tetapi secara jelas tidak disinggung sifat-sifat yang berbeda pada contoh-contoh petai sendiri.Berbicara mengenai keanekaragaman petai, pada akhir bulan Mei 1979 dari pasar besar Padang dikumpulkan contoh-contoh petai yang dijual di sana. Keanekaragaman polong dan biji dibahas.Demikian juga kadar protein bijinya.

Horseflies Tabanus rubidus were reared in the laboratory under 27.5-°C room temperature. Flies from the field layed eggs 5.8 days (i-7 days) and hatching leaching 62.3%.The aquatic larvae required "I i as sheltei plant Two 15 monthsweie needed before larvae could be transfeired to a sintable substrate for pupation. An average of 13.5 days (18-40 days) was required for pupation The total period required to develop from eeg to imago was 109 da\s 92 114 da\s) (sexual ratio between males and females was 1.2 : 1).The first generation of flies obtained could only survue for 9.4 days (5 - 12 days) without ansisn at being abls to produce offspring.

Abstract

Lampung adalah salah satu daerah di Sumatra yang banyak mengalami pembukaan hutan dan pengeringan rawa, yang mengakibatkan menjadi rusaknya habitat dan karenanya berkurangnya lingkungan hidup faunanya. Di antara golongan binatang yang banyak menderita oleh perubahan ini, ialah moluska darat dan air tawar yang akan mengalami penurunan populasi, yang tidak mustahil akan berakhir dengan kepunahan. Untuk mendapatkan data fauna moluska dari daerah Lampung yang telah dan akan dibuka hutannya serta dikeringkan rawanya, maka dalam tahun 1974 - 1975 telah. dilakukan pengumpulan di sepanjang Daerah Aliran Sungai (DAS) Wai Sekampung.

Tolerance of salak seeds on moisture content, temperature and fungal attack.Berita Biologi 3(8): 390 -395.Salak (Salacca edulis var.amboinensis) seeds are difficult to withstand in long term storage.For keeping its viability in storage their tolerance on moisture content,temperatur and fungal attack were studied.Decreasing moistur content influenced salak seed viability. Salak seeds would not afford to sprout.If moisture content reached 24.9%.By moisture content of 47.5%,seed viability dropped to 50.00%.Treatment of storage at temperatures of 10°C, 15 C and 20 C decreased moisture content sjid fungal attack less than at 25°C' and control. Dipping Dithane M45 treatment decreased fungal attack obviously, but it also reduced seed viability.

Abstract

Berbagai  pelestarian jasad renik telah digunakan orang dalam usaha mengurangi pekerjaan rutin pemeliharaan sualu koleksi biak jasad renik dalam jumlah besar.Salah satu cara tersebut dilakukan dengan menggunakan minyak mineral.Cara ini berasal dari Lumiere dan Chevrotier yang dalam tahun 1914 mengadakan penelitian gonokokus (Hartsell 1956).Beberapa peneliti seperti Ungermann, Michael, Morton dan Pulaski merupakan pelopor penggunaan cara tersebut untuk melestaiikan biak bakteri (Fennell, Raper & Flickinget 1950). Sherf merupakan orang pertama yang dalam tahun1943 menggunakan cara tersebut untuk melestarikan biak kapang (Buell & Weston 1947, Fennell, Raper & Flickinger 1950).Di Pusat Penelitian Botani - LBN (Laboratorium Treub), cara tersebut telah digunakan oleh Chaulan (1951) dalam tahun 1948.Dengan menggunakan minyak motor SAE 20 steril ia berhasil melestarikan sebanyak 74 dari 112 biak kapang selama 8-20 bulan, serta 81 dari 94 biak khamir selatna 10 bulan. Tetapi ia tidak berhasil melestarikan biak Sporobolomyces.Dari catatan yang ada pada arsip lembaga, dalam tahun 1961 biak-biak yang ditumbuhkan kembali oleh Chaulan itu dan sebagian koleksi biak lainnya dipindahkan ke media miring agar taoge dalam tabung reaksi.Setelah tumbuh dengan baik biak-biak ini dilestarikan dengan minyak parafin, disimpan tegak dalam lemari kayu dalam suhu kamar.Dalam tahun 1976 biak-biak tersebut dicoba ditanam kembali.Hasil penanaman kembali biak-biak kapang ini dilaporkan dalam tulisan berikut ini

Abstract

D.I. HARTOTO, SULASTRI & I. RACHMATIKA. 1985. Reproductive pattern of some Cyprinids species at Lebak Lebung flood plain area,Lubuk Lampan, South Sumatera. Berita Biologi 3(3): 128 - 135. -A study on reproductive characteristics of three Cyprinids species was conducted in Lubuk Lumpam; a floodplain area in South Sumatera during the early rainy season of 1981. A study of fecundity supported by other biological aspects was used as an approach to reveal the reproductive pattern. Analysis of the Osteochilus hasselti showed that the fish was an early and multiple spawner that strats to breed in a submerged vegetation habitat type before the peak of food abundance in the rainy season. All of the species could not be grouped as small brood spawners, including the least fecund fish Rasbora lateristriata that spawns late in its life span. Chela oxygasteroides showed a similar pattern to the two other species except that it was predicted to spawn during the time of food abundance. Based on Horn's diagram, recapitulation analysis on factors of reproductive strategy indicated that three Cyprinids could be grouped as r - strategist.
