Abstract

Community-based forest management program provides the access for communities to participate in managing state forests. One of them is conducted through agroforestry planting pattern in village forest. The purpose of this research is to know the performance of agroforestry management on land managed by Sumur Kumbang village community in Protected Forest Management Area of Rajabasa. The data collection was got through by interview and observation; the data obtained were analyzed descriptively. The results show the performance of agroforestry management in protected forest management area of Rajabasa in moderate performance (productivity 84, sustainability 167, fairness benefit 88, and efficiency 168). Such performance is influenced by forest management system, ie controlled lands and individually controlled forest products; agroforestry business orientation is commercial; and forest structure is a complex agroforestry. Therefore, the Protected Forest Management Unit of Rajabasa and related stakeholders should develop community capacity and strengthen local institutions continuously so that their forests can be managed in a fair, beneficial, and sustainable way.Keyword : agroforestry; village forest; protected forest management unit; performance..Program pengelolaan hutan berbasis masyarakat memberikanakses bagi masyarakat untuk berpartisipasi mengelola hutan negara;salah satunya dilakukan melalui pola tanam agroforestri di hutan desa. Tujuan penelitian ini untuk mengetahui performa pengelolaan agroforestri pada lahan-lahan yang dikelola oleh masyarakat Desa Sumur Kumbang di wilayah Kesatuan Pengelolaan Hutan Lindung (KPHL) Rajabasa. Pengumpulan data dilakukan dengan wawancara dan obsevasi, data yang diperoleh dianalisis secara deskriptif.Hasil penelitian menunjukkan performa pengelolaan agroforestri di wilayah KPHL Rajabasa dalam performa sedang(produktivitas 84;keberlanjutan 167; keadilan manfaat 88; dan efisiensi 168). Performa tersebut sangat dipengaruhi oleh sistem pengelolaan hutannya, yaitu penguasaan lahan dan hasil hutan yang dikuasai secara individu, orientasi usaha agroforestri bersifat komersial, dan struktur hutan merupakan agroforestri kompleks. Oleh karena itu, KPHL Rajabasa serta stakeholder terkait harus mengembangkan kapasitas masyarakat dan menguatkan kelembagaan lokal secara terus menerus, sehingga hutannya dapat dikelola secara adil, bermanfaat, dan berkelanjutan.Kata kunci : agroforestri; Hutan Desa; KPHL; performa.

Abstract

Harvesting of natural production forest with selective cutting system creates felling gaps and reduces canopy cover. Treefall gaps play important roles in forest ecology. The information of size and form of treefall gaps due to low harvest intensity (0,58 tree ha-1) in tropical natural forest is poorly established. This study aims to calculate the size of treefall gaps and to correlate nature of felled tree (tree height, tree diameter, crown height, crown diameter) and slope with size of treefall gaps. The study was carried out in a cutting block of a forest concession in Papua province. The plot used is a circular plot of 1.7 ha. The 15 sample plots were placed in the cutting block randomly. The size of treefall gaps is calculated by measuring the length and wide of area openness after tree felling. The average area of forest gap before tree felling, canopy gaps and expanded gaps respectively was 0,04%, 1,52% (258,7 m2), and 2,66% (451,7 m2). Tree height of felled tree has significant relationship to the size of treefall gaps.Penebangan hutan alam produksi dengan sistem tebang pilih menciptakan ruang terbuka (gaps) dan mengurangi tutupan tajuk. Keterbukaan tajuk hutan akibat penebangan memiliki peran penting dalam ekosistem hutan. Hingga saat ini masih sedikit informasi yang diketahui tentang ukuran dan bentuk keterbukaan tajuk akibat penebangan pohon dengan intensitas rendah di hutan tropis yang dipublikasikan. Penelitian ini bertujuan untuk menghitung luas areal hutan yang terbuka akibat penebangan pohon dengan intensitas rendah (0,58 pohon ha-1), dan menganalisis faktor pohon yang ditebang (tinggi pohon, diameter pohon, tinggi tajuk dan diameter tajuk) dan kemiringan lapangan, yang mempengaruhi luas keterbukaan area hutan akibat penebangan. Penelitian ini dilakukan di salah satu petak tebangan pada salah satu pengusahaan hutan alam produksi di propinsi Papua. Plot contoh yang digunakan adalah plot lingkaran dengan luas 1,7 ha. Jumlah plot contoh sebanyak 15 plot yang tersebar secara acak di petak tebangan. Luas keterbukaan areal hutan dihitung dengan cara mengukur panjang dan lebar areal terbuka setelah penebangan pohon. Ratarata luas keterbukaan tajuk tegakan hutan alam produksi yang belum ditebang sebesar 0,04%. Rata-rata luas keterbukaan tajuk dan areal hutan yang terbuka akibat penebangan pohon dengan intensitas rendah berturut-turut adalah 1,52% (258,7 m2) dan 2,66% (451,7 m2). Tinggi pohon yang ditebang berpengaruh nyata terhadap luas areal hutan yang terbuka akibat penebangan.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh hubungan antara waktu penyadapan dan Usia Tanaman Karet terhadap produksi Lateks. Penelitian dilakukan di desa Tumbang Lahang, Kecamatan Katingan Tengah, Kalimantan Tengah. Penelitian dilakukan menggunakan model desain eksperimental RAL (Rancangan Acak Lengkap) desain faktorial 3 x 2 dengan 5 kali ulangan. Hasil penelitian menunjukkan bahwa pohon-pohon karet berusia 15 tahun menghasilkan lateks lebih besar dibandingkan usia 7 tahun dan 11 tahun. Pada usia 15 tahun memiliki rata-rata produksi 56,2 gram, sedangkan pada usia 7 tahun dan 11 tahun adalah 50,0 gr dan 48,5 gr. Hal ini karena pada usia 15 tahun pertumbuhan pohon telah stabil sehingga dapat melakukan aktivitas fotosintesis dengan baik dan sel-selnya mengandung pembuluh lateks lebih banyak dari pada dua usia lainnya sehingga pada 15 tahun produksi lateks lebih tinggi dibandingkan usia 7 dan 11 tahun. Selain umur tanaman diketahui bahwa produksi lateks di pagi hari pada jam 06-07 menghasilkan 54,69 gram sedangkan pada jam 09-10 pm adalah 48,47 gr karena penyadapan yang dilakukan pagi 06- 07:00, bersamaan dengan keadaan turgor pembuluh lateks masih tinggi sehingga keluarnya lateks dari pembuluh lateks yang terpotong berlangsung dengan aliran yang kuat.This study aims to determine the effect of the relationship between time and age intercepts the production Latex Rubber Plant. The study was conducted in the village tumbles Lahang, District Middle Katingan, Central Kalimantan. The study was conducted using an experimental design model CRD (completely randomized design) 3 x 2 factorial design with 5 replications. The results showed that the rubber trees aged 15 years to produce latex is greater than the age of 7 years and 11 years. At the age of 15 years had an average production of 56.2 grams, while at the age of 7 years and 11 years was 50.0 g and 48.5 g. This is because at the age of 15 years of tree growth has been stable so that it can perform photosynthesis activity well and the cells containing the latex vessels are more than the two other age so that in 15 years the production of latex is higher than the ages of 7 and 11 years. In addition to the age of the plant known that the production of latex in the morning at 06-07 hours to produce 54.69 grams whereas in the 09-10 pm hour was 48.47 g for wiretapping conducted 06- 07:00 am, along with the state of turgor latex vessels still so that discharge of the high latex latex vessels severed in progress with a strong flow.

Abstract

Land use conducted in accordance with its ability to protected areas or farm area in a watershed will provide benefits for the benefit of the water system and the welfare of society. Land use do not match the capabilities and purposes may increase the risk of floods. Balitbangda South Kalimantan (2010) states that the period from 2007 to 2010, flood in Banjar regency as many as 10 districts and 65 villages. The purpose of this research is to know the land ability class become the reference for determining the direction of the use and the utilization of the land, While the expected benefits to be a reference for flood control measures for the short and long term. The determination of land capability class is done through spatial approach method by utilizing Geographic information system. The study results obtained: 1) domination of the land capability class parameters:  a) slope, > 65% area of 31.46%; b) drainage, either 94.2%; c) The volume of surface rocks, lots of 36.5%; d) the erosion was 49.7%; e) the soil depth in 66.6%; f) soil texture, subtle bit; sandy clay, clay 57.95%. 2) land capability class sub-watershed Riam Kiwa sub watershed Martapura III to VIII. 3) Flood control optimally through forest rehabilitation based on land capability class in the sub watershed Martapura.Banjir merupakan suatu kondisi aliran air sungai pada suatu DAS yang tingginya melebihi muka air sungai normal, sehingga melimpas dari palung sungai yang menyebabkan adanya genangan pada lahan rendah disisi kiri kanan sungai. Penggunaan lahanyang dilaksanakan sesuai dengan kemampuannya pada kawasan lindung dan atau kawasan budidaya pertanian pada suatu DAS akan memberikankeuntungan untuk kepentingan tata air  dan kesejahteraan masyarakat. Penggunaan lahan yang dilakukan tidak sesuai dengan kemampuan dan peruntukannya dapat meningkatkan risiko bencana banjir. Balitbangda Provinsi Kalimantan Selatan (2010) menyatakan bahwa periode 2007-2010 terjadi bencana banjir di Kabupaten Banjar sebanyak 10 kecamatan dan 65 desa. Tujuan penelitian ini  mengetahui kelas kemampuan lahan menjadi acuan penentuan arahan penggunaan lahan, sedangkan manfaat yang diharapkan agar dapat menjadi acuan pengendalian kerawanan banjir untuk jangka pendek dan jangka panjang.  Penentuan kelas kemampuan lahan dilakukan melalui metode pendekatan secara spasial dengan memanfaatkan sistem informasi Geografis. Hasil kajian diperoleh : 1) dominasi parameter kelas kemampuan lahan: a) kelerengan, > 65 % seluas 31,46 %; b) drainase, baik 94,2%; c) Volume Batuan Permukaan, banyak 36,5%; d) erosi sedang 49,7%; e) kedalaman tanah dalam 66,6%; f) tekstur tanah, Agak halus; liat berpasir, lempung 57,95%. 2) kelas kemampuan lahan sub-sub DAS Riam Kiwa sub DAS Martapura III sampai IV dan VI sampai VIII. 3)Pengendalian banjir secara optimal melalui rehabilitasi hutan dan lahan berdasarkan kelas kemampuan lahan di sub DAS Martapura Kabupaten Banjar.
