Abstract

The achievement of the reforestation is expected to reach a climax forest ecosystem. The objectives of this studywas to develop soil index model on monitoring of reforestation achievement. The study used a statistical approach to obtain soil index model to determine the achievement level of reforestation in mining area. The achievement indices for each variable were derived from the best regression model developed, while the weights of eachvariable were computed based on magnitude of regression coefficient for each indicator. The level of reforestationachievement index was initially developed by the use of 4 indicators, i.e. physical soil, biological soil, chemical soil, and litter index. Of those indicators, the study revealed that the heights weight for reforestation monitoring was chemical soil, which is composed pH, cation exchange capacity (CEC), macro-micro nutrient, and base saturation.

Abstract

Spora cendawan mikoriza arbuskula (CMA) telah dikoleksi dan diisolasi dari berbagai jenis tanah masam berfikasi P-tinggi di Indonesia. Lima isolate CMA lokal telah berhasil diperoleh dari spora tunggal dengan teknik “test tube culture” dan dikembangkan-biakan dengan sistem “open pot culture”. Kelima isolate tersebut adalah Acaulospora delicata (EJ-01). Acaulospora tuberculata (INDO-2), Glomus manihotis (INDO-1), Glomus mosseae (PAL-03) dan Entrophospora colombiana (LAM-36). Kelima biakan isolate CMA tersebut, dipelihara dengan tanaman inang Kudzu pada media zeolit yang diperkaya nutrisi. Dengan mempelajari berbagai tipe media, ukuran partikel, pH dan komposisi nutrisi, isolate CMA terpilih telah berhasil dapat diperbanyak dalam skala industri dengan menggunakan inang sorghum. Dengan tehnik pra-inokulasi di persemaiaan maka penggunaan mikoriza dalam skala besar di bidang kehutanan dapat direalisasikan.

Abstract

The objective of this research is to find out the early information of optimum light intensity and highest mycorrhizal colonization on natural Ramin seedling which it includes in semitolerant plant. The research was conducted in Ramin Natural Forest of Sungai Pelunjung Labai, Sanggau District, West Kalimantan for a year. The results of the research show that there are correlations between light intensity with mycorrhizal colonization. Ramin seedling which grown under the light intensity 3190 – 9500 lux have high mycorrhizal colonization and their growth better than the other treatment. Meanwhile Ramin seedling which grown in closed area or in open area with light intensity less than 1670 lux and more than 10840 lux respectively have lower mycorrhizal colonization and their growth was lower.Key words: Ramón seedling  (G. bancnus), Light intensity and Mycorrhizal Fungi

Abstract

Land rehabilitation of post-mining must be done with reforestation. Reforestation success in post-mining revegetation should to refer the characteristics of natural forests.  The success of the reforestation is expected to reach a climax forest ecosystem.  How much time is needed to achieve the desired condition (success reforestation), in this case described as the age of achievement expectations of reforestation success to reach a climax forest ecosystem (the basalt area).  The research is aimed to predict reforestation success age.  The study used regression analysis for determining the reforestation success age in mining area.  The measure used to determining the reforestation success age is basalt area (LBDS) of natural forests.  Mathematically it can be summarized to LBDS = f (age).  The study found the age of achievement expectations of reforestation success is 75 years.  Over the 75 years when the efforts to improve, protect and enhance forest functions are be done well, consistently, and even continued to rise, certainly reforestation success will be achieved, or even faster.   Key words: rehabilitation, mining area, reforestation, basalt area, reforestation success age
