Abstract

Mengacu pada Undang Undang Republik Indonesia Nomor 23 Tahun 2008, sejak tanggal 24 Juni 2008 Kabupaten Labuhanbatu Utara (Labura) mulai berdiri sendiri sebagai kabupaten dan terpisah dari Kabupaten Labuhanbatu Selatan. Pada dasarnya wilayah pemekaran memiliki tujuan untuk meningkatkan kesejahteraan masyarakat. Berdasarkan data BPS tahun 2019, sektor unggulan dan mata pencaharian di Kabupaten Labura adalah pertanian. Akan tetapi seiring berjalannya waktu usaha pertanian semakin menurun. Hal ini terjadi diduga karena perubahan tutupan lahan. Secara geografis pemekaran wilayah akan mempengaruhi perubahan tutupan penggunaan lahan. Oleh karena itu untuk mengetahui seberapa besar perubahan yang terjadi perlu dilakukan analisis tutupan lahan tahun 2010-2019, kurang lebih 10 tahun setelah masa pemekaran terjadi. Analisis tutupan lahan satu dekade ini dilakukan menggunakan Citra Landsat yang diolah melalui metode klasifikasi penggunaan dan perubahan lahan. Hasilnya Kabupaten Labura mengalami perubahan yang relatif lambat. Perkebunan karet dan sawit mengalami perluasan lahan yang besar sedangkan hutan mangrove berubah fungsi dominan menjadi perkebunan. Sementara lahan terbuka mengalami perubahan terkecil yang juga mengarah ke perkebunan. Setelah dilakukan analisis tutupan lahan, dilakukan Seleksi Bivariat dengan menggunakan metode Logistic Regression Analysis (LRA) untuk mendapatkan faktor pendorong perubahan. Ada 7 variabel yang diduga mempengaruhi perubahan yaitu 1) jenis tanah, 2) kemiringan lereng, 3) curah hujan, 4) jumlah penduduk, 5) kepadatan penduduk, 6) jarak dari pusat kecamatan, dan 7) jarak dengan jalan utama. Hasil analisis menunjukan 6 variabel mempengaruhi dan hanya 1 variabel yakni curah hujan yang tidak mempengaruhi. Nilai positif pengaruh terbesar adalah jenis tanah. Semakin subur tanah maka perubahan semakin cepat terjadi. Nilai negatif pengaruh terbesar adalah jarak dari pusat kota yaitu kecamatan. Semakin jauh jarak dengan pusat kota, perubahan semakin cepat terjadi. Hal ini terjadi karena perkebunan dan pertanian yang lebih banyak mengalami perubahan berada jauh dari pusat pemukiman kecamatanan. Rekomendasi berupa perlunya zonasi tata ruang dan pengawasan alih fungsi lahan.

Abstract

The main activities in the rural landscape are agriculture, involved natural resources management that compose the function of area as settlement, government services, social services and economy activities.  These activities affected the rural landscape that changed plant diversities as well as carbon stock. The aim of this research was to evaluate biodiversity and carbon stock in the rural area of Cisadane Watershed.  Two villages were defined on a purposive random sampling, i.e. Sukadamai and Bantarsari.  The sampling plots were selected based on main land use type with size for tree was 20 m × 20 m, pole was 10 m x 10 m, sapling was 5 m x 5 m and seedling was 2 m x 2 m; with 3 replications.  Similarly, other concentric plots were established. The number of plant species were counted, diameter at breast height (DBH) and plant height were measured.   The analysis of carbon stock, plant diversity and the relationship was developed using Microsoft Excel and R 3.6.1 software.  The results showed that main land use in Sukadamai and Bantarsari Village consisted of settlement area, farmland, mixed farming and palm oil plantation.  In the research area where 106 species from 43 families that classified into 9 horizontal diversity based on function and 5 vertical diversity based on plant height. The values of Shannon-Wiener Diversity Index (H’) ranged 2,78–3,20.  Estimated carbon stocks were 1,16–51,40 Mg ha−1 in research areas, respectively. These research concluded there was a negative correlation between species richness and diversity index with carbon stock in the village landscapes.ABSTRACTThe main activities in the rural landscape are agriculture, involved natural resources management that compose the function of area as settlement, government services, social services and economy activities.  These activities affected the rural landscape that changed plant diversities as well as carbon stock.
