101 | Ecological And Ekonomic Aspect Of Complex Agroforest Systems in Indonesia | Ecologically the agroforest systems could be comparable to mature secondary forests. The multispecies and multilayer structure of the vegetation create condition, in which flow of nutrient between different plant species is favoured and nutrient loss is kept at minimum level. Agroforest systems are managed sustainably by the farmers. Agroforest systems play important role in agricultural economy in Indonesia and are important sources of income for millions of smallholder farmers. From viewpoint of socio-economic aspects, agroforest systems can be considered as social forestry. So they could be complemented with overall forest policy and development. Development of agroforest systems as sustainable farming methods in Indonesia needs better knowledge on the interaction between trees and other vegetation components; biology of wild fruit and timber producing trees, end products processing and marketing. | agroforest, biodiversity, nutrient cycle, economy | Titiresmi dan Yudhi Soetrisno Garno | |

104 | By Product Exchange of Seaweed Solid Waste for Mushroom Media | A laboratory experiment on utilization of seaweed-containing solid wastes as media for growing mushrooms was conducted by researchers from the Institute for Environmental Technology. The solid wastes were obtained from PT. Agarindo Bogatama, a food industry which produces jelly powder processed from seaweed of Gracilaria. The company generates 60 tones of solid wastes of seaweed per-day that contained 70% of water content. The solid media was used to grow Auricularia polytricha, Pleurotus astreatus, and Ganoderma lucidum. Some mixed media were prepared with the percentage ratio of sawdust to solid waste as 0, 25, 50, 75, and 100. After sterilization the media were planted with mushrooms and then were kept in incubator. After 28-day the basidiomas of G. lucidum was developed while P. astreatus appeared after 36-day of incubation. Both were grown on 100% seaweed media (using 100% sawdust media as a control). This very early results indicated that solid waste of seaweeds have an additional value which can be used as media for mushrooms plantation. Implementation waste to product as a part of cleaner production approach should be disseminated to the industries, especially SMEs like PT. Agarindo Bogatama, who are concern to the environment. | Byproduct exchange, seaweed solid waste, mushrooms | Titiresmi | |

108 | Pemanfaatan Lahan tidur di Bawah Tegakkan Hutan Rakyat dengan Tanaman Nilam | The agroforest region is bestowed with diverse agro-climatic zones, which makes itself a rich storehouse of different types of flora and fauna. Besides, this conditions help in introduction, acclimatization, and cultivation of a number of aromatic plants with minimum efforts. There are a few commercial crops, which can be cultivated without disturbing the existing flora and have the potential to establish as cash crops in this region. Patchouli (Pogostemon cablin Benth) has been identified as one such essential oil bearing aromatic plant with immense export potential. Patchouli oil production could be a rural based, labour intensive, low cost agro-base cottage industry, which will give large-scale employment in rural and hilly areas. Patchouli, being a shade loving plant can easily be grown as an intercrop amidst fruit trees, arecanut, and coconut plantation etc. It can also be easily cultivated in flood free fallow or wastelands. This will provide some extra income for the farmers. Following report of experiment in Cibojong-Padarincang-Serang clearly indicates that Patchouli cultivation can be a good option besides the traditional crops. | Agroforest, intercrop, shading, nilam, Pogostemon cablin | Titin Handayani dan Titi Resmi | |

112 | Potensi Tumbuhan Liar Dari Lokasi Penampungan Limbah Tailing PT.Antam Cikotok Untuk Fiteromendasi | Detoxification of cyanide contaminated soils and waters with plants seems to be a feasible option in these decades. The plant types that are of particular interest for use as remediation are those that absorb, store and under certain circumstances, detoxify contaminants. Since plants vary in their ability to accumulate specific contaminants, it is necessary to identify candidate plant species that can both accumulate and tolerate the contaminants of concern at a given site. For this purpose screening appropriate plant species adapted to local conditions should be seriously considered. Therefore this study aims to characterized plants that grow under extreme contaminated media of gold mined sites i.e tailing dam that belongs to PT ANTAM Cikotok and to analyse the capacity of their potency as hyperaccumulator. The results showed that some plant species, which grow in the contaminated areas, indicated high tolerance and potentially affective in accumulating cyanide in their roots and above ground portions. Some of these plants are known as cover crops i.e Centrocema pubescens Beth and Mucuna purients DC. Other species are Chromolaena odorata (L.) R.M King and H. Robinson, Cleome aspera Koen ex Dc, Jussieua peruviana, Melastoma malabatricum Liin, Mikania cordata (Burm.f.) B.L.Rob, Paspalum conjugatum Berg that known as weeds and Solanum torvum Swartz that known as vegetable.
