Abstract

Hutan mangrove Pantai Tanjung Bastian memiliki luas lebih kurang 37 ha. Jumlah tersebut mengalami penurunan dari tahun ke tahun (Anonimous, 2005). Hal ini disebabkan karena banyaknya pemanfaatan hutan mangrove untuk berbagai keperluan diantaranya areal pertambakan, keperluan pemenuhan kayu bakar dan bahan bangunan untuk kepentingan sendiri dan komersial, infrastruktur pantai termasuk pelabuhan, pembangunan tempat perdagangan dan perumahan, pengembangan pariwisata yaitu wisata alam serta pertanian. Berbagai aktivitas yang terjadi pada hutan mangrove Tanjung Bastian memberikan dampak kurang baik terhadap vegetasi, di antaranya terjadi perubahan komposisi dan struktur vegetasi pada berbagai tingkat pertumbuhan seperti anakan, pancang, tiang, dan pohon. Tujuan kegiatan pengabdian ini adalah: 1) Pemberdayaan masyarakat untuk selayaknya menjaga populasi mangrove yang ada di pesisir pantai tanjung Bastian. 2) Menumbuhkan kesadaran dan motivasi bagi masyarakat pesisir untuk menanam kembali mangrove sebagai bentuk kepedulian terhadap lingkungan pesisir. Metode kegiatan yang digunakan dalam kegiatan ini adalah penyuluhan dan pendampingan penanaman mangrove. Hasil kegiatan yang didapat bahwa setelah dilakukan penyuluhan tentang potensi dan bahaya kerusakan ekosistim mangrove, masyarakat merasa sangat antusias melakukan penanaman bersama. Dampak dari kegiatan ini adalah mulai ditanamnya manggrove khusunya pada areal tambak.

Abstract

Lontar (Borassus sundaicus,Beck) adalah jenis palma yang tumbuh di daerah kering. Di Indonesia, lontar banyak ditemukan di Nusa Tenggara Timur. Produk utama lontar adalah nira dari sadapan bunga, dapat diminum langsung atau diolah jadi gula. Nira yang dijadikan sumberdaya unggulan daerah ini perlu dikembangkan, sebab memberi nilai tambah terhadap pendapatan perkapita dan kesejahteraan.Pemanfaatan nira lontar sebagai gula merah cetak di Kabupaten Timor Tengah Utara (TTU) masih dominan dilakukan oleh warga etnis Sabu dan Rote. Sedangkan masyarakat lokal, suku Dawan dominan memanfaatkan nira lontar untuk minuman beralkohol (sopi). Di Kabupaten TTU, Kota Kefamenanu Kelurahan Maubeli terdapat pohon lontar yang belum dimanfaatkan. Terutama yang memproduksi nira lontar menjadi gula merah cetak. Alat, bahan seadanya dengan proses pembuatan tanpa melalui tahapan penyaringan secara baik. Sehingga penampilan gula merahnya kurang menarik. Dampaknya harga pasaran gula di bawah harga pasaran gula merah dari daerah lain yang sudah olah secara higienis.Tujuan kegiatan pengabdian ini adalah pemanfaatan nira lontar sebagai gula merah cetak melalui pelatihan dan pendampingan serta perbaikan tahapan pengolahan secara higienis, dengan perlakuan media kemasan yang menarik untuk peningkatan harga dan pendapatan petani. Hasil gula merah cetak petani mulai diterima dipasaran toko maupun mini market di kota Kefamenanu. Dampak yang dirasakan petani yakni pendapatan meningkat.

Abstract

Peningkatan karbondioksida (CO2) di atmosfer merupakan salah satu penyebab terjadinya perubahan iklim dunia. Pengurangan emisi CO2 melalui berbagai vegetasi hutan sangat diperlukan. Keberadaan hutan mangrove di wilayah pesisir utara Kabupaten Timor Tengah Utara dapat berperan dalam penurunan kandungan gas CO2. Ekosistem mangrove mampu menyerap rata-rata 8 ton CO2 / ha/ tahun. Nilai ini kurang lebih 2 kali hingga 4 kali lebih besar dari pada nilai pengamatan secara global terhadap hutan tropis yang lebat. Tujuan penelitian untuk mengetahui biomassa dan serapan karon pada tegakan mangrove pantai utara Kabupaten Timor Tengah Utara. Penelitian ini telah dilaksanakan pada bulan Juni - Agustus 2020. Penentuan lokasi penelitian menggunakan purposive sampling. Setiap lokasi ditempatkan plot – plot pengamatan. Penentuan jumlah plot mengikuti petunjuk Indriyanto (2006). Terdapat 7 plot yang tersebar pada 3 lokasi penelitian yakni pesisir pantai Wini, pesisir pantai Oepuah dan pesisir pantai Tuamese. Pada setiap plot dilakukan pengukuran diameter. Perhitungan biomassa menggunakan persamaan allometrik sesuai dengan persamaan allometrik dari masing – masing jenis yang ditemukan. Hasil penelitian menunjukan bahwa konribusi terbesar dalam penyerapan karbon pantai utara Kabupaten Timor Tengah Utara adalah dari jenis Rhizophora sp yakni dari spesies Rhizophora apiculata. Rata - rata Biomassa tegakan mangrove pantai utara adalah sebesar 13,6 ton/ ha dengan cadangan karbon sebanyak 23,61 ton/ ha
