Abstract

PT INCO Tbk. is one of the biggest nickel mining company in the Asia-Pasific region and has been operated commercially in Indonesia since 1978. It is located at Sorowako, South Sulawesi Indonesia with  the area up to 218.000 hectares. The mining operation process is surface mining. It eliminated the existing vegetation, and it will lead to soil erosion, loss of biodiversity, damage of wildlife habitats and degradation of watershed area, considering with these negative impacts a revegetation programme is fully needed (Setiadi 1995). Revegetation that has been done obstacled by the marginal land conditions where soil structure has been damaged and it has became a lateritic soil. It absorbs elements of phosphate (P), which is essential for plant life. It will be poor of P-available that can be absorbed by plants. Therefore input for more effective technology and environmentally friendly is needed, among others by applying a bio-technology Arbuscular Mycorrhizal Fungi biofertilizer (AMF). It has some functions, one of them is increasing nutrients absorption, especially P. Therefore, research on the existence of mycorrhizal status needs to be done as an introduction for research and application of mycorrhizal in the rehabilitation field of post- nickel mining.

Abstract

Global warming is one of the major environmental issues that currently concern to the various parties. Because of global warming, increasing in average temperature of earth's sea and land caused by industrial activity and reduction of forest cover due to deforestation, especially lately. Based on these evolving issues and considering the importance of the role of forests in absorbing carbon from the air and store it in forest biomass, it is necessary a lot of research that could encourage the continued development of carbon in biomass. One important aspect of research is to know the potential of carbon stored in the stands of pine.

Abstract

Agroforestry is one of society based forest management which have had important role to maintain and recover land productivity since years ago. Ecological consideration was needed for such agroforestry which involve the use of natural resources sustainable, by minimizing erosion and surface flow volume, and also biophysical environment. Jatropha planting was aimed to fulfill market demand of Bio-fuel as alternate energy. This research was aimed to quantify jatropha’s growth and land productivity in jatropha based agroforestry system; also to observe how jatropha based agroforestry system affected environmental change (soil physical, chemical and biological properties, and soil erosion). The result showed that the best jatropha’s growth response to height was the jatropha planting treatment as fencing in young mahogany plot. Land productivity showed by increasing total above-ground biomass rised the highest level in 2nd repetition of young mahogany plot, jatropha plant above ground biomass increased high in 1st repetition plot of  young mahogany. Surface flow showed incisive decrease in young mahogany plot (with the smallest mean value). The jatropha based agroforestry system mixed with young mahogany also showed the lowest erosion level. The highest value of sedimentation was showed in marginal area as control treatment, and the lowest in jatropha based agroforestry system mixed with young mahogany. Content of soil C-organic, total-N and CEC were increase during observation, though jatropha planting was not significantly affected soil physical and chemical properties. The 2nd jatropha plantation mixed with young mahogany plot showed the best response to fungal content. Particularly jatropha based agroforestry mixed with young mahogany showed better impact on soil quality than marginal area.

Abstract

One of Forest and Land Participatory Rehabilitation Program (RHLP) is the implementation of agroforestry system. Agroforestry chosen as the solution of optimal land utilization so it would provide additional output value of either physical or financial results.This research aims to study more the growth of Sandalwood (S. album) as primary tree in some agroforestry.  Field activities done at Sanirin Village, Balibo Sub District, and Bobonaro District. The observed dimensions of main crop were height, diameter, length and width of the tree canopy. Biophysical environmental conditions of soil properties and tree canopy closure were also observed. Data was taken from several agroforestry patterns. The data then analysed descriptively to the growth parameters of main crops associated with the pattern of developed agroforestry and its management techniques. There are there types of agroforestry pattern, named AF1, AF2 and AF3. Each of AFs has combination of crops such as AF1 combination of S. album,Tectona grandis L., Sweteniasp., Aquilarium sp., Cajanus cajan, Zea mays, Cucurbita pepo, AF2 combination  S. album,Sesbania sp., Cajanus cajan, Zea mays, Cucurbita pepo and AF3 is combination of S. album, Tectona grandis L., Swetenia sp., Zea mays, Manihot utilisima. The AF3 has worst performance in height and diameter growth, while AF2 is having best performance in height and diameter growth. In the crown covered, the AF2 type is gained highest percentage compared to the others. The results showed that the growth of primary tree in agroforestry pattern to produce cassava is the lowest thanto the others .The availability of P and K elements suspected to be the cause of low growth of primary crop. Land management activities are only focused on the productivity of agricultural crops caused the crops and the main crop is uneven.

Abstract

Tailing is one form of waste produced in large quantities in the gold mining activities are nutrient poor. Therefore it is necessary for land revegetation in these tailings. Revegetation activities must be conducted on former mining land, but often encounter obstacles that revegetation efforts are quite heavy. The success of revegetation on land that is dominated by tailings require plants that are able to adapt as mahagony seedling (Swietenia macrophylla), which has the potential if planted in dry soil as the soil tailings. This study used a complete randomized design. The results showed 30 grams of compost fertilizer effect is very real influence with the percentage growth of 40.70% against the control with an average growth of 6.81 cm.

Abstract

Sengon  (Paraserianthes falcataria  (L) Nielsen) is widely planted for reforestation programs, especially in establishment of community forest as its timber is utilized for constrction, package box, lighter as well as raw material of pulp and paper. However, there is main problem in sengon plantation, which is boktor (Xystrocera festiva Pascoe) pest attact. In the midgut of boktor larvae it was detected trypsin and α-amylase enzymes activity. Whereas on sengon tree it was reported contains inhibitory substance against trypsin and α-amylase enzymes of boktor larvae. The inhibitory activity was assumed as defense mechanism of sengon tree against the pest attack. In order to clarify the assumption an investigation on the correlation between trypsin and α-amylase inhibitor of sengon with larval growth on an artificial diet is necessary. The experiments aimed at obtaining correlations between the activities of trypsin and α-amylase inhibitors of sengon tree with the growth of boktor larvae, with small (±1,5 cm) and big sizes (±3 cm) on an artificial diet containing respective sengon tree materials.

Abstract

Legume  Cover  Crop  establishment  is  vegetative  method for  erosion  control  in  the  slope  area.  Calopogonium mucunoides, Centrosema pubescens, and Pueraria javanica are the species  are uses as mixed  Legume Cover Crop for erosion control. The problem in cover crop planting on slope area is the seed easy wash away by the rain, so erosion control in the slope area can not be implemented properly. The Templok Method is a new method for planting Legume Cover Crop in the slope area. This method use TeraGlue as kohesif material, for straw or litter as planting media and cocofiber net. This research done at area with  ± 70° slope in Gunung Walat Forest Education, Sukabumi.           The result of this research indicate that Templok Method by using TeraGlue, straw and litter media also cocofiber net can give good effect of planting Legum Cover Crop in the slope area. Based on this first research, Templok Method can be use as alternative solution for planting Legum Cover Crop for erosion control in slope area.

Abstract

The need for teak wood processing in Indonesia is still high both for domestic demand and export wood demand. But the shortage of teak wood demand can give opportunities for people to cultivate teak on their privately land. The purpose of this research is to examine the main plant growth of teak (Tectona grandis Linn F.) in small scale private forest and compare it with teak’s growth from monoculture forest at Perum Perhutani KPH Sumedang in same ages. The main data of plant dimensional were taken with census method from teak plants in each of the selected land such as height, canopy diameter and canopy projection. In this research, soil parameter observed consist of physical and chemical content of soil  samples  from  each  selected  land  then  analyzed  in  laboratory.  Crown  closure  data  taken  by  using  a  spiracle     densiometer. The history of land management known by interview with farmers in each selected land. Those data were analyzed descriptively.            The results showed that the observed forest have 3 (three) different age classes of teak plantation. They are teak plant with  class  age  of  3  years,  6  years,  and  12  years  whom  the  growth  of  teak  are  different  in  those  parameter  such  as diameter, height, crown closure and basal area. Growth of teak plantation in the village of Babakan Asem is a plant with  the best teak growth among the other villages. Their growth maybe influenced by several factors, that is  the condition of the site or soil condition factors and cultivation activities. The result of crown closure show that the majority of sunlight blocked  by  the  crop  canopy  of  teak,  so  less  than  40%  of  sunlight  can  reach  the  soil  surface.  That  condition  maybe affected by size crop of teak and the distance between teak plantation it self. The result of soil analysis indicated that  physical and chemical soil content in Conggeang District are impact on teak growth which bulk density, water storage, KTK, pH, and other chemical substance are related to teak diameter’s  growth.             Growth  of  teak  plantation  between  small  scale  private forest  and  Perum  Perhutani  were  significantly different  in class  ages of  3 and 12 years  and didn’t  different  at  class ages of  6 years  in diameter.  The difference in  teak growth between  small  scale  private  forest  and  Perum  Perhutani  are  caused  by  a  factor  of  using  teak  seed  and  the  forest management.

Abstract

Growth of Jabon (Anthocephalus cadamba  Roxb. Miq.) on PT ANTAM Unit Bisnis Pongkor’s Tailing with Top Soil and Compost AdditionGold  tailing has some characteristics such as low of organic material and microorganism activity, deficient in nutrition andlow of CEC (cation exchange capacity). This constraint to revegetation, therefor soil amandment needed before revegetation program. Top soil and compost addition, which can improve soil condition and nutrition, also as microbe source.It is necessary to select tree species for revegetation post mining activity. Pioneer species that chosen have to well adaptive, fast growing, known silviculture techniques, available in plant resource, microbial symbiosis and catalytic. One of the potential species is jabon (Anthocephalus cadamba Roxb. Miq.). The result of this research is growth respon of jabon on  tailing with  top soil and compost addition can improve growth of tall, stem diameter  and root biomass. The best dose combination are 20 grams compost combine with 250 grams top soil.
