Abstract

ABSTRAK Kabupaten Tanjung Jabung Barat memiliki kawasan Hutan Lindung Gambut Sungai Bram Itam seluas 15.965 ha, namun dalam perkembangannya mengalami tekanan alih fungsi lahan yang begitu hebat. Alih fungsi lahan yang semula berupa hutan beralih menjadi lahan perkebunan, pertanian, pemukiman, dan infrastruktur fisik lainnya. Dengan kondisi yang demikian maka lahan gambut mengalami degradasi baik kualitas, dan tentunya kuantitasnya. Pada Kawasan HLG Bram Itam telah terjadi perubahan tutupan lahan yang signifikan. Alih fungsi lahan yang terjadi pada HLG Bram Itam menyebabkan perubahan kondisi biofisikawalnya, sehingga terjadi perbedaan kelembaban karena areal yang tertutupi vegetasi akan memiliki kelembaban yang lebih tinggi dibandingkan dengan areal terbuka. Alih fungsi yang dominan adalah kelapa sawit , Pinang dan Kopi liberika. Alih fungsi lahan yang terus meningkat cenderung mengurangi tutupan hutan di HLG Bram (KPHL). Penginderaan jauh merupakan teknologi yang sangat dibutuhkan untuk memperoleh informasi mengenai penutupan lahan dan vegetasi yang cepat, akurat dan efisien, Salah satu pemanfaatan data citra Landsat adalah untuk mengetahui sebaran suhu permukaan (LST) dan Kerapatan vegetasi (NDVI). Melalui analisis spasial diperoleh peta TVDI (Temperature Vegetation Dryness Index), maka dapat diperoleh informasi sebaran kelembaban Hutan Lindung Gambut Bram Itam. variabel yang digunakan dalam menentukan faktor utama sebaran kelembaban adalah Pengukuran nilai Normalized Difference Vegetation index (NDVI), dan Perhitungan nilai Land Surface Temperature (LST). Hasil menunjukkan pada hutan lindung gambut Bram Itam vegetasi jarang mempunyai luas 500,30Ha; vegetasi sedang mempunyai luas sebesar 2372,22Ha; dan vegetasi rapat 9760,99 Ha dan memiliki nilai suhu minumun 10,32⁰C dan suhu maksimum 27,91⁰C dengan nilai suhu rata-rata 20,19⁰C. Model TVDI = (LST – (44,688 * NDVI – 2,5128)/(-53,5156 * NDVI – 29,2388)). hasil model TVDI kawasan hutan lindung gambut Bram Itam pada tahun 2017 memiliki 4 kelas yaitu kelas agak basah (9525,14 Ha), kelas normal (2775,68 Ha), kelas agak kering (226,73 Ha), kering (9,57 ha). Kata Kunci: Kelembaban, NDVI, LST, TVDI. ABSTRACT KPHP Limau is one of the KPH located in Jambi Province. People in the KPHP Limau area, namely in Lubuk Bedorong village, mostly use Non-Timber Forest Products (HHBK) to meet their daily needs by making handicrafts in the form of woven. Craft making is carried out by the Tani Harapan Bersama Group which was established in 2017 and has been developed by KPHP Limau since 2019. However, there are obstacles due to the lack of equipment availability, low human resources and a small scope of marketing so that production is still limited and not optimal. Lubuk Bedorong Village has the potential of HHBK in the form of handicrafts in the form of woven that is able to contribute large enough to improve welfare, but the community and local government do not realize how much economic value the craft products. The purpose of this study is to find out and calculate the economic value of woven bamboo and rattan crafts. This research was conducted in Lubuk Bedorong village from September to October 2020. The focus of research on the use of HHBK, namely bamboo and rattan, and the limits that will be studied are only about the economic value of woven handicraft products from bamboo and rattan. Respondents are determined by census or saturated sampling, namely 45 respondents as KTH members. Economic value data is taken by way of structured interviews with the help of questionnaires. The data analysis method used is quantitative. The results showed the economic value of bamboo and rattan handicraft products in 2018 and 2019. The economic value of bamboo and rattan handicraft products in 2018 is still relatively low, which is Rp. 171,000,000,-/Year because the production is still using traditional equipment, KTH members are still few and marketing is still low while in 2019 the economic value is quite high, which is Rp. 648,160,000,-/Year because KTH has cooperated with KPHP Limau and has helped in the marketing process and provided modern equipment so that KTH Can produce new craft products in greater quantities in a short time. Keywords: Humidity, NDVI, LST, TVDI.
