Abstract

ABSTRACT. This research aims to gain information on the magnitude and forms of openness of the land due to the activities of TPTI in RKT 2016. Sample data retrival implemented in area IUPHHK-HA PT. Aya Yayang Indonesia, sub Muara Uya, Tabalong Regency, located on a swath of work 21U, 22U, 20V, 22V, and 21V. The objects of research are areas of IUPHHK-HA PT. Aya Yayang with the collected parameters is a form of land cover changes from forest into non-forest. The total number of samples as much as 66 samples. The research method used is a purposive sampling method and analyzed with overlay, overlay image interpretation results of GPS data, measuring Planimetris, the calculation of the level of openness and tabulate. Research resultsshowed the form of openness of the land in the form of roads logging, skid trails, camp production, TPn, a Bush/shrub and fields for activity outside the logging activities. The magnitude of the openness of the land due to the activities of the fifth on a swath of TPTI work of 58.42 Ha of the total area of the fifth working swath 500 Ha. The openness that could be assessed a percentage of openness just lay in theswath of 21V, due to have been 100% in working on logging. The vast openness of the land on a swath of 21V 26.98 ha with percentage of openness 26.98% of total area of 100 ha and is the swath of openness laha by category "medium" according to Regulation PHPL year 2016.Keywords: Openness; Land Cover; Image of Sentinel-2ABSTRAK. Penelitian ini bertujuan untuk memperoleh informasi tentang besarnya dan bentuk-bentuk keterbukaan lahan akibat kegiatan TPTI di RKT 2016. Sampel pengambilan data diaksanakan pada areal IUPHHK-HA PT. Aya Yayang Indonesia, Kecamatan Muara Uya, Kabupaten Tabalong, terletak pada petak kerja 21U, 22U, 20V, 21V, dan 22V. Objek penelitian adalah wilayah IUPHHK-HA PT. Aya Yayang dengan parameter yang dikumpulkan adalah bentuk perubahan tutupan lahan dari hutan menjadi non-hutan. Jumlah keseluruhan sampel sebanyak 66 sampel. Metode penelitian yang digunakan adalah metode purposive sampling dan dianalisis dengan overlay hasil interpretasi citra, overlay data GPS, pengukuran Planimetris, perhitungan tingkat keterbukaan dan tabulasi. Hasil penelitian menunjukan bentuk keterbukaan lahan berupa jalan logging, jalan sarad, camp produksi, TPn, semak/belukar dan ladang untuk kegiatan di luar kegiatan penebangan. Besarnya keterbukaan lahan akibat kegiatan TPTI pada kelima petak kerja sebesar 58,42 Ha dari luas total kelima petak kerja 500 Ha. Keterbukaan yang dapat dinilai presentase keterbukaannya hanya terletak pada petak 21V, dikarenakan telah 100% di kerjakan penebangan. Luas keterbukaan lahan pada petak 21V sebesar 26,98 ha dengan persentase keterbukaan 26,98% dari luas total petak 100 ha dan merupakan keterbukaan laha dengan kategori “Sedang” menurut peraturan PHPL tahun 2016.

Abstract

The purpose in this research to analyze the dominance and minimum livelihood values of the vegetation types that make up the mangrove forest ecosystem. The vegetation data were collected using the grid line method to record all growth rates. Vegetation data from observations and measurements were analyzed using the Importance Value Index (INP) formula approach and the Minimum Life Value (NKM) for each type of vegetation analyzed using the Frangklin formula.The results of the vegetation analysis used the Importance Value Index (IVI), the order of the top vegetation dominance at the seedling, sapling, pole and tree levels for the Male Mangrove (Rhizophora mucronata Lamk). The Minimum Livelihood Value (NKM) of all species found in the study exceeded 0.1. NKM shows that the condition of the plants in the research location is still preserved. The mangrove forest in the research location needs serious attention from the government (central and regional), especially to develop the dominant species, namely male mangroves (Rhizophora mucronata Lamk), as well as to implement integrated ecosystem conservation management efforts and provide counseling about the importance of mangrove conservation around the coast beachTujuan penelitian untuk menganalisis dominasi dan nilai keterhidupan minimum jenis-jenis vegetasi penyusun ekosistem hutan mangrove. Pengambilan data vegetasi menggunakan metode garis berpetak untuk merekam semua tingkat pertumbuhan. Data vegetasi dari hasil pengamatan dan pengukuran dianalisis menggunakan pendekatan formula Indeks Nilai Penting (INP) serta Nilai Kehidupan Minimum (NKM) masing-masing jenis vegetasi dianalisis dengan formula Frangklin. Hasil analisis vegetasi berdasarkan nilai Indeks Nilai Penting (INP), didominasi pada tingkat semai, pancang, tiang dan pohon jenis Bakau Laki (Rhizophora mucronata Lamk). Nilai Keterhidupan Minimum (NKM) dari semua jenis yang ditemukan dalam penelitian melebihi dari 0.1. Berdasarkan NKM menunjukan keadaan tumbuhan di lokasi penelitian masih terjaga kelestariannya. Hutan mangrove di lokasi penelitian perlu mendapat perhatian serius pemerintah (pusat dan daerah) terutama untuk mengembangkan jenis-jenis yang dominan yaitu bakau laki (Rhizophora mucronata Lamk), serta menerapkan upaya pengelolaan konservasi ekosistem secara terpadu dan mengadakan penyuluhan tentang pentingnya pelestarian mangrove di sekitar pesisir pantai
