Kedudukan geografi Pulau Pinang dan Melaka yang terletak di pantai barat Semenanjung Malaysia, merupakan lokasi penting untuk pendaratan penyu. Kajian telah dijalankan di kedua-dua lokasi ini, dan data taburan sarang penyu agar, Chelonia mydas di Pulau Pinang (dari tahun 2010 hingga 2014) dan penyu karah, Eretmochelys imbricata di Melaka (dari tahun 2013 hingga 2014) dibekalkan oleh Jabatan Perikanan Malaysia dengan kebenaran pihak Jabatan untuk menerbitkan keputusan kajian. Objektif kajian ini bertujuan untuk menentukan musim bersarang penyu agar di Pulau Pinang, menentukan kecenderungan pilihan ruang-masa (spatiotemporal) bagi sarang penyu karah di Melaka, menentukan tapak pemilihan sarang bagi penyu agar di Pulau Pinang, dan menentukan kajian keberjayaaan penetasan menggunakan Kaedah Rekaan Pecahan Telur. Jumlah sebanyak 265 sarang penyu agar telah dikenalpasti terdapat di Pulau Pinang dalam tempoh lima tahun (2010-2014). Jumlah sarang tertinggi dikenalpasti tertumpu di Kerachut, dan jumlah sarang kedua tertinggi dikenalpasti di Teluk Kampi, diikuti oleh Teluk Aling, Teluk Duyung, dan Pasir Pandak. The geographic locations of Penang Island and Melaka along the west coast of Peninsular Malaysia provide important nesting beaches for marine turtle nesting. A study was conducted at these two nesting beaches, and nesting data of the green turtle, Chelonia mydas in Penang Island (from 2010 until 2014) and hawksbill turtle, Eretmochelys imbricata in Melaka (from 2013 until 2014) was supplied by the Department of Fisheries, and permission granted to publish the results. The objectives of the study were to determine the seasonality of green turtle nesting in Penang Island, spatiotemporal preferences in nesting of hawksbill turtle in Melaka, nest site selection of green turtle in Penang Island, and hatching success of green turtle by using a Split Clutch Design Method. A total of 265 green turtle nests were identified in Penang Island within a five-year period (2010-2014). The highest number of nests was observed at Kerachut, and the second highest total was observed at Teluk Kampi, followed by Teluk Aling, Teluk Duyung, and Pasir Pandak.
