Abstract

The blue-black urchin has been widely known and utilized as food in the world, including Indonesia because sea urchin gonad can be consumed. However, the utilization of sea urchins in Gorontalo has not been performed. On the other hand, natural resources information is needed as the database for natural resources management in Tomini Bay. The aim of this study is to document the blue-black urchin Echinotrix diadema. This study conducted at Blue Marlin Beach, South Leato, Gorontalo, from November 2019 to December 2020. Sea urchin density was calculated with a 1 m × 1 m transect quadrate that positioned at interval 5 m in distance along 15 m of the transect line at the coral reef ecosystem. In parallel with the measurement of the density, sea urchin test diameter was measured with a Vernier caliper (0.01 mm accuracy), and the water temperature was measured with a thermometer. The results show that the average of sea urchin density is 3 ind. m–2 in November and December and 1 ind.m–2 in January. That density has no significant difference among the month. Moreover, the average size of the sea urchin test diameter is 60 mm in November, 63 mm in December, and 66 mm in January. The seawater temperature is 34 °C in November, 37 °C in December, and 33 °C in January. That results show that sea urchin density in the blue marlin beach is very low.

Tempat Mengurus Surat Keterangan Sehat Jasmani di Kota Makassar

Makassar (14/01/2019)—Ada banyak tempat mengurus surat keterangan sehat Jasmani di Kota Makassar. Namun, pada hari ini, saya memilih untuk mengurusnya di BBLK, Dinas Kesehatan Kota Makassar. Photo credit: La Nane (dokumentasi pribadi) Saya memilih di sini, karena pelayanannya cukup baik dan super cepat.  Itu pengalaman saya, kemarin saat mengurus Surat Keterangan Bebas Narkoba untuk kelengkapan berkas CPNS. Photo credit: La Nane (dokumentasi pribadi) Baca Juga: Mengurus Surat Keterangan Bebas Narkoba di Makassar. Saking cepatnya, untuk pengurusan surat keterangan sehat jasmani, hanya memakan waktu 10 menit saja. Tanpa perlu antri yang cukup lama seperti di Rumah Sakit Umum yang super antri panjang. Selain itu, pegawainya cukup cekatan dan ramah-ramah. Dari bagian depan, saat saya pertama datang. Saya ditanya sama pegawai bagian depan "Mau urus apa Mas?"

Cara Menggunakan ATM 77 Bank di Jepang

Penulis menyadari bahwa anda merupakan pengguna ATM pemula di Jepang, sehingga anda mencari informasi mengenai penggunaan ATM ini. Sebelum saya menjelaskan cara penggunaan ATM Bank 77, saya ingin mengatakan terimakasih, karena saya bisa membantu anda dalam menjelaskan cara menggunakan ATM. “Sebaik-baik manusia adalah mereka yang memberi manfaat kepada sesamanya.”     – HR. Thabrani Sobat sekalian, perlu anda ketahui bahwa semua ATM Bank 77 yang ada di Jepang menggunakan bahasa Jepang alias “Nihonggo”. Karena itu sebelum anda mencoba menggunakan ATM yang anda miliki tersebut, Anda perlu menghafal huruf kanji di bawah ini. お預け入れ   :  Deposit (Memasukkan Uang) お引き出し   :  Withdrawal (Penarikan Uang) お振込み :  Transfer ke Rekening Lain お振り替え :  Transfer ke rekening lain milik sendiri (jika punya 2 rekening) 通長記入 :  Pencatatan di Buku Rekening (Mencetak Buku Rekening) 残高照会 :  Sisa uang (Mengecek Saldo) Semua tombol-tombol di atas

Cara Mengaktifkan LINE Pay di Jepang

LINE Pay adalah uang elektronik dari LINE chatting khusus untuk kamu yang tinggal di Jepang saja. Kegunaan LINE Pay hampir mirip dengan kartu kredit, karena bisa digunakan untuk berbelanja di Family Mart, LAWSON, 7Eleven, SEIYU dan semua toko yang menerima pembayaran elektronik dengan logo JCB. Bedanya kartu kredit dengan LINE Pay; kalau kartu kredit tagihan pembelian akan tertarik melalui akun rekening bank pemilik, sementara LINE Pay akan langsung mengurangi isi saldo. Jadi pastikan saldo LINE pay cukup sebelum membeli sesuatu. Lalu bagaimana cara mengaktifkan LINE Pay. 1. Masuk ke aplikasi LINE Chatting 2. Tekan ..... Lalu masuk/tekan menu LINE Pay  3. Jika anda sudah memiliki akun LINE pay,  Maka akan muncul sisa saldo uang elektronik anda. Namun  jika anda belum memiliki akun LINE pay, anda bisa mendaftar terlebih dahulu. Caranya tekan add Money, lalu pilih LAWSON Deposit 4. Setelah anda masuk ke LAWSON deposit, Klik link "Apply for a LINE deposit". S
