Abstract

Morning call in siamang is very important for the life of siamang. This behavior is important to mark its territory, communicate with neighboring groups, etc. The this research aims to determine the time of vocalization, the position of trees and the strata canopy used by gibbons in vocalization. This research was conducted in WWF Indonesia Central Sumatra Research Station Subayang Camp at Rimbang Baling Wildlife Reserve for 2 months from July until August 2017 using Visual Encounter Survey (VES) method. From this research we knew that morning call in siamang usually occurs from 08.00 am – 10.00 am in the morning. Siamang appears to choose emergent tree in the forest ridge or emergent tree on the hill slope to do vocalization. During vocalization, siamang tends to use the 3rd and the 4th strata or upper canopy layer and emergent layer which are higher than 20 m from the forest surface. This height facilitates the siamang to maximize transmission of the vocalization to the surrounding area and communicate with other groups.

Abstract

Tujuan dari penelitian ini untuk mengetahui penerapan keselamatan dan kesehatan kerja (K3) pada pekerja Zakiyah Wedding Decoration. Penelitian ini menggunakan metode penelitian kualitatif. Teknik pengumpulan data dilakukan melalui wawancara dan dokumentasi. Informan dalam penelitian ini terdiri dari 2 informan utama yaitu pemilik usaha Zakiyah Wedding Decoration, dan koordinator dekorasi. Selain itu terdapat dua informan pendukung yaitu 2 kru dekorasi. Hasil penelitian menunjukkan bahwa upaya penerapan keselamatan dan kesehatan kerja dilakukan melalui beberapa langkah, seperti pemberian tunjangan kesehatan kepada pekerja, pembagian tugas sesuai kemampuan masing-masing anggota tim, kerja sama dalam mengangkat barang berat, serta pelaksanaan briefing sebelum berangkat ke lokasi dekorasi. Selain itu, pengawasan langsung oleh pemilik usaha juga dilakukan selama proses pemasangan dan pembongkaran dekorasi untuk memastikan pekerjaan berjalan dengan baik. Namun demikian, penerapan K3 masih bersifat sederhana dan belum didukung dengan penggunaan alat pelindung diri secara khusus.
