Telah dilakukan penelitian mengenai perilaku lumba-lumba hidung botol (Tursiops aduncus) di Ocean Dream Samudra (ODS) Jakarta Utara pada tanggal 18 Juni 2015–8 Juli 2015. Tursiops aduncus dikenal sebagai hewan yang memiliki kemampuan beradaptasi yang tinggi terhadap kondisi lingkungan sekitarnya. Hal tersebut memungkinkan Tursiops aduncus dapat bertahan hidup pada habitat buatan. Penelitian bertujuan untuk menghitung proporsi waktu aktivitas harian dan menganalisis bentuk-bentuk perilaku adaptasi Tursiops aduncus di kolam Underwater Theater ODS, serta merujuk perilaku di habitat alaminya. Penelitian dilakukan dengan metode focal animal sampling dengan interval waktu 10 menit tanpa jeda. Individu yang diamati adalah empat ekor Tursiops aduncus jantan bernama Kuning, Ungu, Biru dan Specta yang terdapat pada kolam Underwater Theater ODS. Hasil penelitian menunjukkan persentase perilaku travelling dan perilaku feeding tertinggi ditunjukkan oleh Kuning (65,71%) dan (0,2%), persentase perilaku resting dan perilaku playing paling tinggi ditunjukan oleh Specta (25,68%) dan (2,67%), serta persentase social interaction dan sexual aggression tertinggi ditunjukan oleh Ungu (15,35%) dan (4,94%). Meskipun kondisi pada habitat buatan berbeda dengan habitat aslinya, Tursiops aduncus mampu menyesuikan diri melalui perubahan perilaku yang terlihat pada masing-masing perilaku yang terjadi dan masih mempertahanklan perilaku alaminya.

Telah dilakukan penelitian pola perilaku harian lumba-lumba hidung botol Indo-Pasifik Tursiops aduncus (Ehrenberg, 1833) jantan di kolam pentas lumba-lumba Taman Safari Indonesia Bogor, Jawa Barat. Struktur kelompok sosial pada lumba-lumba jantan tanpa kehadiran individu betina serta kondisi kawasan penangkaran mampu menyebabkan keragaman perilaku pada hewan tersebut. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis perilaku harian lumba-lumba jantan di kolam pentas lumba-lumba Taman Safari Indonesia Bogor tanpa kehadiran individu betina. Subjek yang digunakan pada penelitian ini yaitu lima individu lumba-lumba jantan. Metode yang digunakan pada penelitian ini adalah scan sampling dengan interval waktu 10 menit tanpa jeda dan ad libitum. Penelitian dilakukan pada periode Maret—April 2023 selama 6 pekan dengan total waktu pengamatan 10.800 menit. Hasil penelitian menunjukkan bahwa perilaku harian untuk setiap individu teridentifikasi memiliki pola yang sama dengan rerata frekuensi perilaku harian tertinggi ke rendah adalah traveling > interaction > resting > feeding > playing with object. Selain itu, perilaku seksual yang teridentifikasi pada penelitian ini hanya perilaku homoseksual dengan frekuensi yang cukup tinggi pada kelima lumba-lumba jantan dikarenakan ketidakhadiran lumba-lumba betina. Penerapan prinsip Five Freedoms of Animal Welfare yang dilakukan oleh Taman Safari Indonesia Bogor pada lumba-lumba sebagian besar telah terpenuhi melalui upaya pemeliharaan yang dilakukan. ......Research has been conducted daily behavior patterns of male Indo-Pacific bottlenose dolphins Tursiops aduncus (Ehrenberg, 1833) in dolphin show pool Taman Safari Indonesia Bogor, Jawa Barat. The social group structure of male dolphins without the presence of female individuals and the conditions of captive area is capable of causing behavioral diversity. The aim of this study were to identify and analyze daily behavior of male dolphins in dolphin show pool Taman Safari Indonesia Bogor without the presence of female individuals. The subjects in this study were five male dolphins. The methods that used in this study are scan sampling and ad libitum with an interval of 10 minutes without interruption. The study was conducted in the period March—April 2023 for 6 weeks with total observation time of 10.800 minutes. Based on the result of this study, daily behavior for each individual has the same patterns with the average frequency of highest to low daily behavior is traveling > interaction > resting > feeding > playing with object. In addition, sexual behavior identified in this research is only homosexual behavior with a fairly high frequency in five male dolphins due to the absence of female dolphins. The implementation Five Freedoms of Animal Welfare by Taman Safari Indonesia Bogor in dolphins has largely been fulfilled through maintenance efforts carried out.

Telah dilakukan penelitian mengenai perilaku lumba-lumba hidung botol Indo-Pasifik (Tursiops aduncus) terhadap kehadiran manusia di kolam program Swimming with Dolphin Taman Safari Indonesia Bogor, Jawa Barat. Kehadiran manusia dapat menjadi faktor utama yang memengaruhi perilaku lumba-lumba di kolam pemeliharaan ex-situ. Penelitian bertujuan untuk mengidentifikasi perilaku lumba-lumba terhadap kehadiran manusia dan menganalisis pengaruh kehadiran manusia di sekitar kolam terhadap frekuensi dan pola perilaku lumba-lumba. Penelitian dilakukan pada bulan Maret—April 2023 dengan total waktu 10.800 menit. Subjek penelitian yang diamati berjumlah empat individu lumba-lumba yang terdiri dari dua individu jantan dan dua individu betina. Metode yang digunakan adalah scan sampling dengan interval waktu 10 menit tanpa jeda dan ad libitum. Pencatatan meliputi perilaku harian lumba-lumba saat terdapat kehadiran manusia dan saat tidak terdapat kehadiran manusia di sekitar kolam. Kategori perilaku harian yang diamati pada penelitian ini meliputi traveling, feeding, resting, interaction (social & human), dan playing with object. Hasil penelitian menunjukkan adanya perbedaan pada pola dan frekuensi dari perilaku lumba-lumba saat terdapat kehadiran manusia dan saat tidak terdapat kehadiran manusia di sekitar kolam. Terdapat dua pola perilaku harian yang berbeda pada saat terdapat kehadiran dan tanpa kehadiran manusia. Berdasarkan uji Mann Whitney pada α = 0,05 menunjukkan bahwa terdapat perbedaan yang signifikan pada frekuensi perilaku traveling, feeding, resting, social interaction, dan interaction with human dari keempat subjek lumba-lumba terhadap kehadiran dan tanpa kehadiran manusia. Respons perilaku subjek lumba-lumba terhadap kehadiran manusia dipengaruhi oleh usia, karakter, dan lama waktu proses adaptasi. Implementasi kesejahteraan hewan telah diterapkan dalam kegiatan pemeliharaan di kolam program Swimming with Dolphin. ......Research has been conducted on the behavior of Indo-Pacific bottlenose dolphins (Tursiops aduncus) towards human presence in program Swimming with Dolphin pool Taman Safari Indonesia Bogor, West Java. Human presence can be a major factor influencing dolphin behavior in ex-situ rearing ponds. The study aimed to identify dolphin behavior towards human presence and analyze the influence of human presence around pool on frequency and patterns of dolphin behavior. The study was conducted in March—April 2023 with a total time of 10.800 minutes. The subjects of the study observed amounted to four dolphin individuals consisting of two male individuals and two female individuals. The method used is scan sampling with a time interval of 10 minutes without pause and ad libitum. Records include the daily behavior of dolphins when there is human presence and when there is no human presence around the pond. The categories of daily behavior observed in this study include traveling, feeding, resting, interaction (social & human), and playing with objects. The results showed differences in the pattern and frequency of dolphin behavior when there was human presence and when there was no human presence around the pond. Based on the Mann Whitney test at α = 0.05 showed that there were significant differences in the frequency of traveling, feeding, resting, social interaction, and interaction with human behavior of the four dolphin subjects to the presence and absence of humans. The behavioral response of the dolphin subject to human presence is influenced by the age, character and length of time of the adaptation process. The implementation of animal welfare has been implemented in maintenance activities in program Swimming with Dolphin pool
