This research aims to evaluate the diversity of climbing trees for rattan in agroforestry system. The result of this research is expected to be applied as the standard to improve the management in rattan agroforestry. The research was conducted from June to December 2011 in three different villages: Kalemei, Hiran and Liting in Katingan regency, Central Kalimantan. The data were collected via purposive sampling in two different types of land cover i.e rubber agroforestry (RA) and secondary forest (SF), each of system Â had 6 plots and 18 sub-plots of experiment. The evaluation of species diversity was performed by measuring species richness, Importance Value Index, and Diversity Index. Statistic model was constructed by employing the approach in multivariate analysis and cluster analysis. The results indicated that SF had higher species diversity (3.02 â 3.45). The diversity level of RA was higher in Hiran village (3.96), than in the other two villages (<3.0). Â Habitat similarity was characterised by the similar composition and structure of vegetation of both SF and RA in Hiran and Kalemei, but not in Liting. The potential of supporting trees for rattan in RA is rather high as shown by high species density and the presence of trees with high wood density (0.75-0.9g cm-3) to extremely high (>0.9g cm-3) as it found in SF.Keywords: Rattan, rubber agroforestry, climbing trees for rattan, secondary forest

South Barito is an area of rattan and rattan production center of the province of Central Kalimantan, on the other hand is one area that has natural conditions very conducive to the development of rattan. This study reveals how patterns in addition to planting and processing of rattan traditionally also analyze the socio-economic level of society. Research conducted in South Barito regency, District Karau in Two Villages is Bangkuang and New Salat. The village of the second sample is determined gardens and population are farmers who cultivate cane with sampling methods by simple random sampling, because the peasant population is homogeneous, the number of samples in each village 34 respondents or 68 farmers overall. The result showed that in general the rattan garden where the studies were not well-maintained, where the average of respondents (45%) said that maintenance is only performed at the time of going to the harvesting or one for rattan planting. Besides the low price of rattan is led to a reduction of land management / rattan gardens intensively. and production of rattan average yield of 2.6 tons ha-1 or 245.5 clumps of cane ha-1. For the villagers of business administration studies despite conditions that are considered less favorable, but they still look forward to the Government's policy to remain aligned to the Farmers Rattan. In addition, because cane is inherited and used as a hallmark of South Barito society in general.Barito Selatan merupakan daerah penghasil rotan dan sentra produksi rotan provinsi Kalimantan Tengah, selain itu merupakan salah satu wilayah yang memiliki kondisi alam yang sangat mendukung bagi perkembangan rotan. Penelitian ini selain untuk mengungkapkan bagaimana pola tanam dan pengolahan rotan secara tradisional juga menganalisis tingkat sosial ekonomi masyarakat. Penelitian dilaksanakan di Kabupaten Barito Selatan, Kecamatan Karau di Dua Desa yaitu Bangkuang dan Salat Baru. Dari kedua Desa tersebut ditentukan kebun sampel dan populasi masyarakat yaitu petani yang mengusahakan rotan dengan metode pengambilan sampel secara simple random sampling, karena populasi petani bersifat homogen, jumlah sampel di masing-masing desa 34 responden atau keseluruhan 68 petani. Dari hasil penelitian diperoleh bahwa pada umumnya kebun rotan di tempat penelitian tersebut tidak terpelihara dengan baik, dimana rata-rata responden (45%) menyebutkan bahwa pemeliharaan hanya dilakukan pada saat akan dilakukan pemanenan atau satu kali selama rotan itu di tanam. Selain itu rendahnya harga rotan sangat berdampak pada berkurangnya pengelolaan lahan/kebun rotan secara intensif. dan hasil produksi rotan rata-rata diperoleh 2,6 ton ha-1 atau 245,5 rumpun rotan ha-1. Bagi masyarakat Desa studi walaupun kondisi tataniaga yang dianggap kurang menguntungkan, namun mereka masih berharap kebijakan Pemerintah tetap berpihak kepada Petani Rotan. Di samping itu karena pada umumnya rotan merupakan warisan dan digunakan sebagai ciri khas masyarakat Barito Selatan.

Good germination of rattan jernang (Daemonorops draco Blume) seeds will increase germination power, germination rate, and germination value. However, there are still obstacles to germination, because the jernang rattan seeds have a dormancy period. Soaking in Atonic Growth Regulatory Substances (ZPT) is one method that can be used to break thedormancy period of seeds. This study aims to determine the dose and soaking time on the germination value of jernang rattan seeds (D. draco Blume). The study used four treatments and 3 groups/replications. The treatment in this study was the dose of ZPT Atonik, namely 50 CC/Liter, 80 CC/liter, 120 CC/liter, 150 CC/liter. Grouped by immersion time, 24 hours, 48 hours and 72 hours. The results showed that the best germination percentage of German rattan (D.draco Blume) seeds were treated with ZPT Atonik dose of 120 cc/liter and soaked for 48 hours with a percentage of 100%. The best seed germination rate was at 150CC/liter treatment and 24 hours of soaking time, which was 50%/day. The highest germination value was found in seeds treated with ZPT 120CC/liter and soaking for 48 hours with an average of 0.0036%/ day. The conclusion of this study is that the ZPT Atonik dose of 120 CC/liter and 48 hours of soaking time has an effect on the percentage of germination power and germination value, while the ZPT dose of 150 CC/liter with 24 hours of soaking time increases the germination rate

Decomposition of organic matter in the soil is closely related to the presence of soil macrofauna. The better the process of organic matter decomposition, the better the physical and chemical properties of the soil, which, of course, will support soil fertility in a land area. This research aims to determine the presence of soil macrofauna under Jelutung Rawa trees (Dyera polyphylla Miq) in the peatland of the Seedling Garden (KBS) at Palangka Raya University. The research method was conducted by sampling soil macrofauna through Hand sorting method at 25 observation points and Pittfall Trap method at 20 observation points. The observed and identified soil macrofauna were examined in the laboratory using identification guidelines and literature on macrofauna types. The data were analyzed using the Shannon-Wiener species diversity index formula, the Margalef species richness index, the Pielou evenness index, and the calculation of species presence frequency. The research findings revealed 24 species, 23 genera, 20 families, 7 classes, and 3 phyla of soil macrofauna, with a total of 3,579 individuals. The values of the species diversity index (H'), species richness index (Dmg), evenness index (E), and the frequency of soil macrofauna presence (F) at KBS, Palangka Raya University were as follows: H' = 2.303325269 (moderate category), Dmg = 2.810760521 (moderate category), E = 0.724759677 (fairly even category), and frequency of presence, F = 80% - 100%.

The cultivation of swamp jelutong plants on peat swamp land has been widely practiced by communities in Central Kalimantan Province. However, jelutong cultivation efforts are prone to failure due to various factors such as land fires and other factors. The Indonesian government through the Ministry of Forestry in 2003-2005 carried out the Forest and Land Rehabilitation Movement, which involved planting unproductive land in state forest areas and community forests with local species such as jelutong, pulai, balangeran and other species. After almost 20 years of planting Jelutung, information related to the growth and sap potential of Jelutung swamp is not yet available. The purpose of the study was to analyze the potential growth of diameter and height of jelutong plants. This research was conducted for 3 months from October-December 2023. The location of the research was specifically carried out in Jabiren Raya Sub-district (Jelutung plantation of Mr. Margo) and (Jelutung plantation in Jabiren) Pulang Pisau District. The method used to study the dynamics of jelutong plant growth and sap potential was purposive sampling, by selecting and determining jelutong plants based on the age class of jelutong plants with a sampling intensity of ± 5% of the area, the measurement results were analyzed through correlation regression tests in the form of tables and graphs. The results of research conducted in 2 locations show the results of measurements of diameter and height growth of jelutong plants.
