The tropical forest has a unique feature. Its biological and ecological diversity relies on a very complex and interrelated system. Managing the forest sustainably required a wide application in multiple scientific disciplines. Jurnal Silva Tropika is a periodic scientific article and conceptual thinking of tropical forest management covering all aspects of forest planning, forest policy, forest resources utilization, forest ergonomics, forest ecology, forest inventory, silviculture, and management of regional ecosystems. Jurnal Silva Tropika also welcomes the topics that directly or indirectly support tropical forest management, e.g., economics, anthropology, social, and the environment.

Abstract

This research aimes to study the effect of dose NPK fertilizer (15-15-15) provided gradually to growth of Jabon merah seedling (Anthocephalus macrophyllus (Roxb.) Havil) in nursery. The observation was conducted in Research Farm Faculty of Agriculture University of Jambi for 4 months. This study used completely randomized design (CRD) with three replications and five treatments. Dose of fertilizer used was 6 g/seedling, 12 g/seedling, 18 g/seedling, 24 g/seedling and 30 g/seedling. The observed variables are added height, diameter, number of leaves, root dry weight, shoot dry weight, total dry weight and shoot ratio root. Data were analyzed descriptively. The results showed that an increase in the dose of NPK fertilizer (15-15-15) gives a negative impact on the growth of jabon merah seedlings. Dose of 30 g/seedling cause death of jabon merah seedling. Treatments doses of fertilizer 6 g/seedling gives the best results of added height, number of leaves, root dry weight, total dry weight and shoot dry weight. Keywords : Anthocephalus macrophyllus, Dose, NPK fertilizer (15-15-15)

Abstract

The asiatic softshell turtle Amyda cartilaginea (Boddaert, 1770) is one of the reptile commodities included in CITES Appendix II with vulnerable status according to IUCN. High market demand for the asiatic softshell turtle impact on the exploitation in the wild, so that harvest be limited by quota. The reseach was aimed to know the population characteristics of the asiatic softshell turtle harvested or traded. The population characteristics such as demographic parameters and another parameters. Research used asiatic softshell turtle that collected by traders or harvested location in Jambi City and Muaro Jambi District from June 2015 until August 2015. The result showed there 3 death occurs asiatic softshell turtle in one traders, it’s because fishing equipment make wound for asiatic softshell turtle. Asiatic softshell turtle harvested as much as 383 dominated by mature male with body weight 5,1 kg - 10 kg, or not recomended for harvested by LIPI as scientific authority because being in optimal reproductive age. From colors of carapace and form of pikun, asiatic softshell turtle suspected many much from water flow or rivers.

Abstract

Jernang (Daemonorops draco) is one of the most important species belongs to Palmae. It produces the valuable resin that internationally recognized as “dragon blood”. The dragon blood is used for various products such as medicines, cosmetics and other uses as natural colors. However, the knowledge on the silviculture of jernang both in the nursery and plantation is still very limited. Mostly, the people collect the dragon blood resin from the wild. Due to this reason research on the effects of tricho-compost and NPK Fertilizer to the growth of Jernang seedling had been conducted. Completely Randomized Design with three replications and two factors of treatments namely tricho-compost and NPK Fertilizer dosages had been applied. The tricho-compost treatments consisted of three levels namely 0 g of tricho-compost; 250 g tricho-compost/seedling and 500 g trciho-compost per seedling while the NPK fertilizer consisted of 0 g NPK/seedling, 3 g NPK/seedling, 6 g NPK/seedling, 9 g NPK/seedling and 12 g NPK fertilizer/seedling. The data were analyzed using Analysis of Variance (Anova); and Duncan Multiple Range Test (DMRT) with the level of confidence of 95%. The results showed that the interaction between tricho-compost and NPK fertilizer was not significantly different as well as the results of each single treatment Further analysis using DMRT also revealed the same results were there was no significantly different among levels of treatments to the growth of jernang seedling.

Abstract

The research is aimed to provide recommendation on spatial planning of Hutan Desa Lubuk Beringin management. The research was conducted through direct observation, semi-structure interview, visual interpretation and literature review. Based on the interpretation result of Landsat image with acquisition year in 2014, the types of landuse existed over the areas were old jungle rubber, ecotourism potency and environmental services. The analyses for spatial planning of Hutan Desa Lubuk Beringin with the area of 2.602 ha divided by two zones, namely protection zones and utilization zones. The area of Protection zone covered 84% of total area that equal to 2.602 ha. This area has functions to protect the lower areas and to maintain ecological functions contributing the intangible benefits for people around the village forest. Utilization zone has area of 411 ha that equal to 16% of the total area which has been used for mixed garden or old jungle rubber by the villagers. Furthermore, the management of Lubuk Beringin village forest is ruled by the conservation commitment of village (KKD) and managed by the institution called village forest management group (KPHD) Ndendang Hulu Sako Batang Buat.

Abstract

The purpose of this study was to determine the benefit and value of mangrove forest ecosystems on Cagar Alam Hutan Bakau Pantai Timur in the Alang-alang village region, the concept of economic valuation used to quantify the total value of direct benefits and value of the indirect benefits that exist. This research was conducted by field observations and interviews on the field against the respondents using a questionnaire guide. Based on the results obtained mangrove forest ecosystem in the Alang-alang village region has a total economic benefit value of Rp 291.037.310/year with a value contributor greatest benefit is direct benefits value in the form of Non-Timber Forest Products (honey, catching fish, crabs, shrimp, and scallops). The calculation of direct benefits value that is by using the market price method, the results of direct benefit Rp 259.479.000/year. As for the indirect benefits valuation that an assessment of the ecological functions of the area as a seawater intrusion barrier to the success of the productivity of coconut plantation owned by the community with the method of productivity changes to the indirect benefits value obtained Rp 31.567.310/year. Total economic value can be used as a reference or a basis of comparison for the community and the government in determining the policy of the management and utilization of existing mangrove forests.
