Pemanfaatan Mangrove Sebagai Bahan Olahan Pangan di Kampung Anggraidi
Get PDFHutan mangrove memiliki peran penting sebagai penyedia sumber daya alam yang dapat dimanfaatkan secara langsung maupun tidak langsung, termasuk sebagai alternatif cadangan pangan bagi masyarakat pesisir. Namun, pemanfaatannya sebagai bahan makanan masih terbatas pada kelompok tertentu, seperti masyarakat Kampung Anggraidi yang memanfaatkan mangrove pada musim tertentu untuk memenuhi kebutuhan pangan. Penelitian ini bertujuan untuk mengidentifikasi jenis mangrove yang dimanfaatkan sebagai bahan makanan, mendeskripsikan cara pengolahannya, serta menggambarkan upaya masyarakat dalam melestarikan hutan mangrove di Kampung Anggraidi, Distrik Biak Kota, Kabupaten Biak Numfor. Penelitian dilaksanakan pada November hingga Desember 2023 menggunakan metode observasi, wawancara, dan dokumentasi, kemudian dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa terdapat empat jenis mangrove di wilayah tersebut, namun masyarakat hanya memanfaatkan satu jenis, yaitu Bruguiera gymnorrhiza, khususnya bagian buahnya. Buah mangrove diolah melalui proses perebusan, pengupasan, pengirisan, perendaman, perebusan ulang, dan penggilingan hingga menjadi tepung, yang kemudian diolah menjadi berbagai makanan seperti kue cake, keladi tumbuk, dan kue campuran kelapa. Selain pemanfaatan sebagai pangan, masyarakat juga berperan dalam menjaga kelestarian mangrove melalui kegiatan penanaman kembali (reboisasi). Temuan ini menunjukkan bahwa mangrove memiliki potensi sebagai sumber pangan alternatif sekaligus mempertegas pentingnya pelestarian ekosistem mangrove bagi keberlanjutan kehidupan masyarakat pesisir.

Perbedaan Pola Pertumbuhan dan Faktor Kondisi Ikan kakatua Hipposcarus longiceps dan Scarus ghobban
Get PDFABSTRAK
Ikan kakatua dikenal dengan sebutan parrotfish, ikan bayan, lembain, atau anglu adalah kelompok besar spesies ikan laut dari famili Scaridae yang menghuni perairan dangkal tropis dan subtropis di seluruh dunia, terutama pada ekosistem terumbu karang. Ikan Kakatua meskipun bukan target utama penangkapan, akan tetapi sering ditangkap ataupun tertangkap oleh nelayan, dan semakin lama kondisinya semakin mengkhawatirkan akibat tingginya tekanan dan aktivitas penangkapan. Kajian komparasi aspek biologi secara spesifik dari spesies ikan kakatua masih jarang dilakukan, terutama untuk di wilayah Kabupaten Manokwari. Padahal ini hal yang sangat penting dalam mendukung baseline konservasi spesifik wilayah. Penelitian ini bertujuan untuk mengetahui perbedaan aspek biologi yang mencakup rasio jenis kelamin, sebaran ukuran, pola pertumbuhan, dan faktor kondisi ikan kakatua dari spesies Hipposcarus longiceps dan Scarus ghobban. Penelitian dilaksanakan pada bulan April –Agustus 2025. Pengambilan sampel dilakukan secara acak, sampel ikan diperoleh dari pedagang ikan dan atau nelayan langsung di kota Manokwari, Metode penelitian bersifat deskriptif dengan teknik observasi langsung. Jumlah sampel keseluruhan yang peroleh sebanyak 68 ekor. Hasil penelitian menunjukkan bahwa jenis kelamin kedua spesies ikan kakatua termasuk dalam kategori seimbang dengan rasio 1:1. Hasil uji chi-square menunjukkan nilai 0,023 untuk Hipposcarus longiceps dan 0,615 untuk Scarus ghobban, keduanya lebih kecil dari nilai kritis chi-square (3,841), yang mengindikasikan bahwa populasi kedua spesies masih berada pada kondisi ideal untuk mendukung kelestariannya. Distribusi ukuran panjang total dan berat tubuh kedua spesies berbeda; untuk Hipposcarus longiceps, panjang total berkisar 192–380 mm dengan berat 106–730 g, sedangkan untuk Scarus ghobban, panjang total berkisar 210–366 mm dengan berat 134–823 g. Pola pertumbuhan kedua spesies menunjukkan kesamaan, yaitu pertumbuhan bersifat alometrik negatif (b < 3), yang berarti pertambahan panjang lebih cepat dibandingkan pertambahan berat, dengan pertumbuhan Scarus ghobban lebih stabil. Nilai faktor kondisi menunjukkan bahwa Scarus ghobban tergolong gemuk/montok, sedangkan Hipposcarus longiceps tergolong agak kurus. Perbedaan ini mencerminkan variasi fisiologis dan ekologis antar spesies, serta menegaskan bahwa kondisi lingkungan dan ketersediaan pakan berpengaruh terhadap tingkat kesehatan ikan kakatua di perairan

Program Early Grade Literacy (EGL): Bukti Kolaborasi Efektif antara Pemerintah Indonesia dan UNICEF untuk Pendidikan Papua
No full textThis article aims to discuss the Indonesian government’s efforts to establish international cooperation in the education sector, with a particular focus on United Nations Children’s Fund (UNICEF). It particularly examines how UNICEF can contribute to addressing literacy challenges in Merauke District, Papua—one of the areas where students exhibit low reading and writing skills in the early years of primary education. From an international relations perspective, it highlights how education diplomacy can strengthen local capabilities through global cooperation, exemplified by UNICEF’s Early Grade Literacy Program. Drawing on interviews and program report analysis, this study revealed a significant reduction in non-readers, from almost half to less than a quarter, while the number of students who could read and comprehend texts fluently almost doubled. Creative engagement, like the use of songs, teaching aids, and parent education campaigns, proved the effectiveness of international cooperation at a local scale. These findings not only support the inclusive education targets in the SDGs but also reinforce the strategic role of education diplomacy in addressing disparities in marginalized areas.
