Diversifikasi Produk Olahan Mangrove Bisa Meningkatkan Kesejahteraan Masyarakat Pesisir Indramayu
Full text linkPotensi pesisir pantai di Indramayu yang banyak ditumbuhi pohon mangrove itu, merupakan aset berharga yang bisa dimanfaatkan untuk meningkatkan kesejahteraan masyarakat. Namun sayangnya kondisi pantai banyak yang rusak akibat terjangan abrasi, hal itu disebabkan hampir 18 ribu hektare hutan pantai di Indramayu kondisinya kritis. Salah satu penyebab utama kerusakan hutan mangrove di Indramayu karena kurang kesadarannya masyarakat tentang manfaat olahan dari mangrove sehingga bernilai ekonomi. Masyarakat berpendapat bahwa menjadikan hutan bakau sebagai area pertambakan lebih menguntungkan dari segi ekonomi ketimbang memanfaatkan mangrove menjadi olahan makanan, minuman atau menjadi bahan baku kosmetik. Oleh karena itu secara umum tujuan dalam penelitian ini yakni (1) merubah paradigma masyarakat pesisir kabupaten Indramayu bahwa tumbuhan mangrove dapat diversifikasi menjadi olahan makanan, minuman dan obat-obat yang bernilai ekonomi tinggi; (2) meningkatkan kesejahteraan ekonomi masyarakat pesisir Indramayu. Metode yang digunakan dalam penelitian adalah metode survey, yaitu metode yang dilakukan untuk mengadakan pemeriksaan yang berlangsung di lapangan atau lokasi penelitian. Data yang digunakan berupa data sekunder dan primer yang dapat diperoleh di lapangan dan studi literatur. Data yang diperoleh dianalisis menggunakan analisis deskriptif kualitatif. Mekanisme kegiatan penelitian ini bekerja sama dengan (1) dinas kelautan dan perikanan kabupaten Indramayu; (2) Persaudaran Perempuan Nelayan Indonesia (PPNI) kabupaten Indramayu; (3) Kelompok posdaya LPPM Universitas Wiralodra yang tersebar di Kecamatan Juntinyuat, Kecamatan Pasekan dan Indramayu; (4) kepala daerah yang menjadi tempat penelitian. Hasil penelitian ini menghasilkan lima produk unggulan, yakni sirup pidada, dodol pidada, kecap mangrove, teh mangrove dan lulur mangrove.

Full text linkLimbah tahu merupakan salah satu jenis limbah yang mengandung bahan organik yang tinggi, namun sering dibuang ke lingkungan tanpa melalui pengolahan. Metode hidroponik Deep Flow Technique (DFT) merupakan metode tanam tanpa menggunakan media tanah tetapi meletakkan akar tanaman pada larutan nutrisi pada kedalaman 4-6 cm pada sirkulasi nutrisi terus menerus. Metode penelitian dengan menggunakan metode kuantitatif, dan desain penelitian dilakukan menggunakan rancangan acak Lengkap (RAL) dengan membandingkan tiga populasi tanaman selada (Lactuna sativa L) yang ditumbuhkan pada 3 (tiga) perlakuan yang berbeda yaitu pertumbuhan tanaman pada media nutrisi hidroponik AB mix (A1), pertumbuhan tanaman pada media nutrisi limbah tahu (A2) dan pertumbuhan tanaman pada media nutrisi limbah tahu dan kayu apu (Pistia stratiotes L) atau A3. Hasil penelitian menunjukkan bahwa ratio EM4 dan limbah tahu yang optimal digunakan untuk media hidroponik adalah ratio 1 :5 karena mempunyai suhu 270C, pH 7,6 kadar BOD 412,12 mg/L, kadar COD 913 mg/L dan TSS 200 mg/l ; atau paling mendekati standar baku mutu limbah cair menurut Permen LH NO 5 Tahun 2014. Hasil pertumbuhan tanaman selada (Lactuna sativa L) menunjukkan bahwa pertumbuhan tertinggi adalah pada perlakuan menggunakan nutrisi AB mix (A1) yang mempunyai rata – rata ukuran tanaman paling tinggi 15,14 cm, jumlah daun paling banyak 11,7 dan biomassa paling besar 20,96 gr. Uji lanjutan menggunakan DMRT juga menunjukkan bahwa antar perlakuan terdapat beda nyata. Berdasarkan hasil penelitian dapat disimpulkan bahwa pengolahan limbah tahu menggunakan EM4 mampu mengurangi kadar polutan walaupun masih dibawah standar baku mutu. Limbah tahu dapat digunakan sebagai media nutrisi hidroponik meskipun dengan pertumbuhan yang lebih rendah
