Some students presentation have planned and conducted, as follows:


1) 20 MAY 2011:

S3 – MIESKE WIDAYATI: “Evaluation & Reconstruction of Ecovillage and Ecohouse at Inner Baduy Settlement based on Community Sustainability Assessment”
Environment quality is worsening every year; building’s sector contributes 66 % of fossil fuel resources. Global Eco-village Network (GEN), has developed tool called Community Sustainability Assessment (CSA) and define ways that can bring the world to be more sustainable, popular as Eco-village and Eco-house. Today, in spite of new technological advances, techniques and materials, identical buildings are still being built, and climatic design is not considered important. Designer solves a thermal discomfort problem with non-environmental friendly manner using air conditioned or increase in the use of energy. Indigenous people, such as the Inner Baduy community, from longstanding experience has developed systems to control its environment and buildings in a sustainable manner. The aim of this study is to emphasize the importance of traditional knowledge in terms of providing low energy buildings and settlement which adapted to climate. The study is performed in three steps. The first, CSA tool is used to evaluate the ecovillage concept & sustainability of Inner Baduy community. The second, reconstruction of ecohuse concept & building design using sketch-Up program. The third, assessment of passive air conditioning inside building with a numerical simulation using CFD program. The results is a documentation of Eco-village and Eco-house concept in Inner Baduy community that can be used for a knowledge in development of Indonesian settlements in a hot humid climate’s model.

S3 – ABDUL HARRIS BAHRUN:

S3 – HADI PRANOTO: “Analysis of Agroforestry System Characteristics in The Agro-ecological Zones of Cianjur Watershed”. Characteristics analysis of cropping pattern, productivity and social economic of agroforestry were held in the agro-ecological zones, i.e. the upper, the middle and the down stream of Cianjur watershed. The 30 samples of agroforestry plots and interview of 30 respondents have observed in each zone of the watershed. It’s known that the characteristic of agroforestry system is different in each zone. Simple or modern agroforestry system could be found in the upper and the middle zones, furthermore, mixed or traditional agroforestry system wad found in the down stream of Cianjur watershed. Single and multi-commodities by alley cropping design on the whole years with high intensity was found in in the upper stream zone. The cropping pattern of cash crops was found as a single commodity and multi-commodities by alley cropping, regular planting space, and planting on the line and blocks was practiced in the middle stream zone. Mixed cropping pattern with irregular planting space in the mixed gardens was found in the down stream. Plant species selection criteria is different among of the three zones of Cianjur watershed. Based on farmers reason, most of farmers in the upper stream and the middle stream of watershed have economic oriented by planting vegetable and/or cash crops. Crops, which are used for daily consumption, producing seed material its self area found in the down stream. The productivity of annual crops, such as carrot, cabbage, lick , tomato, and chili is high in the upper stream. But, the optimal plant selection have affected to revenue. B/C ratio of annual cash crops is 1.09, 2.89 and 1.02 in the upper, the middle and the down stream, respectyively.

S2 – ARIEF PRASETYA NUGRAHA: “Land Use Changes: Its Impact on Biodiversity And Carbon Stock in Ciliwung Watershed”
Indonesia is the 3rd biggest carbon emitters in the world (World Bank, 2007). Indonesia targets to reduce national emissions 26% on 2020 supporting LCS program. 85% of emissions come from the way we use land, in agriculture, and land use, or conversion of land use in the watershed area. Ciliwung watershed is one of the important watershed in Indonesia, because the river through the capital city of Indonesia (Jakarta) and other satellite cities around it (Bogor, Depok). Currently Ciliwung are experiencing land degradation especially in Jakarta. In addition, Depok and Bogor are also being built and would also impact on river conditions.

S2 – NAHDA KANARA: “Environmental Management Technology subject titled Sustaining A Common Future: Asia and Pacific”
This assignment is the summary of a sub chapter of GEO 4: Environment for Development (United Nations Environmental Program, 2007). The outlines are driver of change and problems in the Asia and Pacific region (transport and urban air quality, freshwater stress, valuable ecosystems, agricultural land use and waste management). To note, Jakarta have highest concentration of NO2 (µg/m3) in selected Asian cities (2002) along with exploding growth in motorized vehicles. In addition, South East Asia sub region, including Indonesia, have a highest biodiversity risk among all sub region in Asia and Pacific.

S2 – WAHYU CATUR ADINUGROHO: “Dynamic and Biomass Carbon Stock In A Bamboo Stand in Okayama, Japan”
Bamboo forests are important ecosystems from various ecological aspects in the world, especially in Japan. Bamboos are known to have the comparatively fast growth rates in the world so do their absorption and stock of CO2 has the potential to mitigate global warming. Even though, Japan have problem with Bamboo stand because the bamboo stand has expanded to an adjacent forest. As the results, Above ground biomass and C-stock in the stand level of P.nigra have increased in outer plot at the rate of 1.59 ton C ha-1 yr-1. It is likely that the biomass and C-stock have attained to a stable condition in inner plot. The total C-stock in that stable condition of P.nigra stands averaged 68.2±2.9 ton C ha-1, which is likely to be similar with other forests or larger than other forests. Therefore, P.nigra stands probably possess a great capacity for carbon dioxide reduction. It is expected that C-stock in the bamboo forests will increase because the bamboo forests have been expanding. However, at the same time we must consider the management so that suitable relations to other forests can be maintained.

3) 24 JUNE 2011

S1 – MUHAMMAD IMANULLAH:

S1 – PRINSA PARUNA: “Prototype of Pekarangan as a Ecopark in Industrial Area of Karawang International Industrial Center (KIIC)”. Karawang is one of the cities in Indonesia that land use and land cover changes is quite high. These changes have positive impact for economic development, but in another hands have negative impact for environment quality. Industrial area is easy to degrading the environment due to waste produced by plants. We can still use the other land to mitigate the problems with make a greenery open space. One model of greenery open space is pekarangan. Pekarangan is a traditional home garden of Indonesia, which is an integrated system with an intimate relationship between humans, plants, and animals. It is well known that this land use has multiple functions such as agroforestry/agrosilvopastural/agrosilvofishery, and conservation of biodiversity. This research has purpose to make a prototype of pekarangan in industrial area. One of important things when make these prototype is function of the plant. The main function of plants in pekarangan is to reduce pollution in the industrial area especially with a indigenous species or local plants. Carbon sequestration can be held by potential pekarangan vegetation.

S1 – UTOMO ZELAN NOVIANDI: “DESAIN TAMAN VERTIKAL PADA CLUSTER PINE FOREST, SENTUL CITY, BOGOR”

S2 – BAMBANG WINARNO: “Agrotourism potency in Cianjur watershed Cianjur Regency, West Java”
Cianjur watershed has 7.467 H area with land use for agricultural c.a. 5.600 ha (75 % of total watershed area). Therefore, it is potentially to be developed and proposed as agrotourism. The research objective is to evaluate the landscape of Cianjur watershed in order to promote as agrotourism destination. Evaluation method of agriculture, tourism, beautification and amenity were approached to determining the suitability of agrotourism area. Therefore, a research to evaluate this activity has been elaborated by agriculture, tourism, beautification and amenity (ATBA) method. Landscape development have to promote sustainable for agriculture, suitable for tourism, esthetically and comfortable as amenity sources. The planning and management agrotourism concepts were derived from triple bottom line benefit strategic aspect ; the first is environmental conservation aspect with approach by agroforestry concept. The second one is community welfare aspect with approach by eco-village, and the third is landscape beautification by amenity services the rate of comfortable scale. The result of ATBA method is 0,18 % of total watershed area (13 Ha) high-level points, 63,38 % (4.755 Ha) middle and 36,14% (2.699 Ha) low-level points for Agrotourism suitability.

S1 – MUHAMMAD IRFAN: Biodiversity Conservation on Landscape Management of Sentul Eco-city.

S1 – ATIK NURWANDA: “Evaluasi Reklamasi Lahan untuk Rencana Pengembangan Wisata Pada Lahan Bekas Tambang di PT. Newmont Nusa Tengara, Sumbawa”. The open pit mining gives effect more and more increased to the biodiversity and human needs. Following that, natural resources have been reduced in both quantity and quality as extraction has become more intensive and extensive than ever before. This thing because of demands for natural resources have dramatically increased and will continue to increase. Land condition after open-mining has not productive anymore and even probably there is the contain of pollutants accumulation or dangerous heavy metal element exceeds health limit threshold. Nevertheless, in another side reclamation business is aimed at as community tourism destination area, a part of occupy, and recreation activity area for the mining company workers−needed deep investigate to plan the land after mining as tourism area. This research will be done at the land region after mining beneath management PT. Newmont Nusa Tenggara (PT. NNT), Sumbawa Island. The main purpose of this research is to inventory tourism development purpose, to evaluate reclamation effort after mining as the plan of tourism area development, and to plan eco-tourism. Gold (1980) approach method will be used in order to investigate the information of site status, requirement necessity of biology and ecology, up to planning level. There’s the analyze of tourism carrying capacity as sub-method to the analyze level uses the formula Y = (D x A)/(CD x TF x43,560).
