Judul: Studi Morfometri Lumba-lumba Hidung Botol (Tursiops aduncus,Ehrenberg 1833) Di Kolam Konservasi PT. Wersut Seguni Indonesia, Kendal
Abstrak: Bottlenose dolphin is composed of two similar species, Tursiops truncatus and Tursiops aduncus. The purpose of this research is to study the external morphology of T. aduncus. This research was conducted in the conservation pond of PT. Wersut Seguni Indonesia, Pantai Cahaya Klampok Sendang Sekucing, Rowosari, Kendal. Four male and two female bottlenose dolphins were used in this research. The average measurements are: TBL (total body length) 210.56.74 cm, SEY (snout-eye length) 21.14.07 cm, RL (rostrum length) 11.81.17 cm, RW (rostrum width) 7.51.51 cm, MWF (maximal width of the flipper) 13.31.21 cm, TW (tail width) 53.82.92 cm, CB (circle of body) 1104.9 cm, and DFL (dorsal flipper length) 31.35.6 cm. The results showed that the size of T. aduncus is smaller compared to T. truncatus while the RL and TBL ratio is greater in T. aduncus. Measurements result indicates that there is no difference between male and female T. aduncus.

Judul: Tingkah Laku Lumba-Lumba Hidung Botol Indo-Pasifik (Tursiops aduncus) di Umah Lumba, Teluk Banyuwedang, Bali
Abstrak: Lumba-lumba Hidung Botol Indo-Pasifik (Tursiops aduncus) merupakan mamalia laut yang umum ditemukan di perairan Indonesia dan telah dikategorikan sebagai hewan hampir terancam punah oleh IUCN, salah satunya akibat tingginya tingkat eksploitasi untuk atraksi mamalia laut. Penelitian ini bertujuan mendeskripsikan tingkah laku Tursiops aduncus di Umah Lumba, Teluk Banyuwedang, Bali. Observasi visual dilakukan pada 3 individu Tursiops aduncus, yaitu Rambo, Rocky, dan Jhony yang telah direhabilitasi sejak September 2019. Ketiga individu dapat diidentifikasi melalui ciri fisik di bagian kepala dan sirip dorsal. Beberapa lumba-lumba telah mengembangkan sifat liar dengan adanya 9 jenis tingkah laku yang mendukung kehidupan di alam, yaitu bernapas, istirahat, jelajah, reproduksi, sosial, berburu, spy hopping, tail clapping, dan sneezing. Sebanyak 3 jenis tingkah laku dikategorikan sebagai tingkah laku dominan karena ditemukan pada setiap sesi waktu penelitian, yaitu bernapas, istirahat, dan jelajah. Program rehabilitasi lumba-lumba sangat penting dilakukan untuk aklimatitasi, adaptasi, dan melatih lumba-lumba bertahan hidup sebelum dilepasliarkan.

Judul: Inducible and constitutive synthesis of penicillinase by staphylococcus aureus
Abstrak: When tested quantitatively for the production of penicillinase, eighteen of one hundred and twenty-two naturally occurring penicillin-resistant staphylococci were classified as constitutive or microconstitutive. Fourteen of the constitutive strains were not typable, the other four were lysed by group III phage. The inducible and constitutive strains of Staphylococcus aureus were resistant to concentrations of mercuric chloride that inhibited strains sensitive to penicillin. Transfer of the penicillinase determinant by transduction from a microconstitutive strain to a sensitive strain resulted in recombinants that produced inducible penicillinase.
