Studi bioakustik mempelajari produksi suara, dispersi melalui media elastis, dan penerimaan pada hewan, termasuk manusia. Intensitas amplitude suara, fluktuasi suara, dan bentuk pola-pola suara ikan. Bioakustik adalah ilmu lintas-disiplin yang menggabungkan biologi dan akustik yang biasanya merujuk pada penelitian mengenai produksi suara, dispersi melalui media elastis, dan penerimaan suara pada hewan; termasuk pada ikan guppy (Poecilia reticulata). Dalam penelitian ini, kadar garam sebesar 2 gram/mol ditambahkan ke dalam air hingga salinitas mencapai 30 ppm. Nilai intensitas awal tertinggi pada ikan guppy yaitu pada setelah penambahan garam pada hari ke 3 dan 7 memiliki intensitas yang lebih tinggi, dengan rata-rata intensitas yaitu berada pada -44 dB pada range waktu yaitu detik 40-50. Studi ini menunjukkan bahwa ikan guppy mampu bertahan pada salinitas 30 ppm dengan nilai intensitas -48 dB dan frekuensi kepakan sirip atau stridulatory ikan guppy adalah 0 sampai 19,6 kHz.

This study observed the behavior male dolphins by doing science approach bioakustik who viewed the characteristics of these dolphins. Male dolphins (Tursiops aduncus) that maintained in Safari Park, Indonesia, Cisarua Bogor has the lowest intensity value amounting to 28.03 dB and the highest amounted to 32,01 dB. With an average parameters ie measurable salinity of 30 ‰ and a temperature of 23 ° C with depth of the pool 4,5 meter. Range frequency clicking sound with the highest intensity value that is equal to 32 dB with a clicking sound 3 after dinner on second day contained in the frequency range is 14 -16 kHz. Click sound frequency range of male dolphins bottle nose (Tursiops aduncus) in Safari Park, Cisarua Bogor, Indonesian have frequency 14,2-15 kHz.
Whistle sound is generally used for echolocation purposes, while the sound of the blast-beat and whistles play a major role in internal and inter-group communication. The purpose of this research is to know the power spectral patterns and fluctuations in sound based on frequency and Power Spectral Density (PSD) of the sounds produced by dolphins and observing the position of dolphins, Noisy Time Domain (NTD) and behavior using underwater camera, and also comparing between time and sound spectrum. Data recording was taken at the Safari Park of Cisarua Bogor in Indonesia, by taking data in show pool and show pool. The results showed that salinity before feeding time in the show pool with replication 1,2, and 3 has salinity value that is equal to 30%. Data at the show pool before feeding with replications 1,2, and 3 has a salinity of 29%. Power Spectral Density (PSD) of the whistle sound before feeding was different from one another, but it has the same frequency range. The highest intensity values is at sound whistle 3 before feeding time at the show pool with an intensity value of 28.03 dB/Hz with frequency interval of 14642-16000 Hz. F-test at the show pool before meals has heterogeneous value. Treat before meals at the show pool has a value of P < 0.001 and P < 0.001. Value Noisy Time Domain has differences with each other and has a lot of different sound patterns. In general, there are real differences are evidenced by F test on a range of time at each whistle on physiotherapy and swimming pool show in the time before meals. The position of dolphins in a pool show more dominant and often in the bottom of the pool, the position of the dolphins affects the frequency.
This study aims to determine the driving factors of social solidarity in PERKIM organizations and forms of social solidarity in PERKIM organizations in Makassar City. The results showed that the driving factor for social solidarity in the PERKIM organization was the economic factor, which was to help each other in meeting the needs of migrants. The religious factor is encouraging friendship, and please help. The cultural factor is that they have the same habits and also the same language so as to make them comfortable and foster a sense of solidarity between them. The form of social solidarity that is mechanical solidarity seen from the lack of interdependence of one another in terms of work, they can cover each other, and the high sense of mutual help to help between them if there is a disaster, and organic solidarity seen from applicable law is restitution where each member who violates will not be immediately sanctioned but will be given a warning first, as well as the existence of an individual nature of each individual in the PERKIM membership.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
