Gunung Walat Educational Forest (GWEF) is one of field laboratories of Bogor Agricultural University (IPB), Indonesia. Faculty of Forestry is the manager and has been searching some sustainable ways to manage the forest. Unfortunately, basic information on GWEF has been lacking, especially related to biological diversity resources. The research was aimed at supporting basic information of GWEF, especially on medicinal plant, and establishing a sustainable management of GWEF based on medicinal plants and mechanisms of reward for environmental services provided by surrounding communities.

The field research was conducted at Gunung Walat Educational Forest IPB from May to July 2002. Methods used were: (1) forest-floor vegetation analysis, (2) interview with surrounding community and stakeholders, and (3) Geographical Information System (GIS).

Gunung Walat Educational Forest is a 359 Ha-manmade forest, which consists of 6 major tree stands from genus Pinus, Acacia, Schima, Agathis, Swietenia, and Albizzia. The Forest-floor Vegetation Analysis resulted in 85 species of forest-floor vegetation, which belong to 46 families. Seventy species of them belong to medicinal plants. According to the interview with surrounding communities, there are 177 species of plants they use for medicines. Only 20 species are found in GWEF, but they utilize only 3 species from GWEF: Achasma megalocheilos Griff. for asthma, Costus speciosus (Koen.) J. E. Smith for rheumatism, diabetes, diuretic, etc., and Selaginella plana Hieron for treatment after giving birth. Interview with stakeholders: Manager of GWEF, Local Government Research and Planning Agency, Forestry Service, and Health Service of Sukabumi Regency, surrounding community, and visitors resulted in their opinion that GWEF must be conserved and best utilized as a sustainable tourism area. Mapping with GIS resulted in spatial distribution of medicinal plant in GWEF. Each stand has a specific relation with medicinal plant found. Pinus stand has the most various medicinal plants due to its large size 110.5 Ha.

Sustainable Management of GWEF based on medicinal plants is how to utilize medicinal plants in this area so that GWEF can increase their income and support their daily management, and how to involve surrounding community so they can gain benefit from the forest. There are 3 suggested activities: (1) cultivation of medicinal plants in GWEF by agroforestry system, (2) establishment of kampong conservation/conservation hamlets by introduction of medicinal plant’s home industry, and (3) promotion of eco-tourism as mechanisms of reward for environmental services.

Location for cultivation of medicinal plants are (1) in bare-land area of GWEF, about 22 Ha, for cultivation of Zingiber officinale Roxb., Curcuma domestica Val., and Alpinia galanga (L.) Swartz, and collection of Imperata cylindrica Ness.; and (2) in agroforestry area, about 100 Ha, for Amomum cardamomum L., Centella asiatica (L.) Urb., Piper betle L., Piper nigrum L., and Piper retrofractum Val. These species are chosen based on their ecological relation to GWEF, their medicinal values, demand of Indonesian Traditional Medicine Industries, and familiar to surrounding communities. Using medicinal plants have been planted by local communities, both from inside GWEF and from their surrounding houses, medicinal plants home industry can be initiated to promote utilization of medicinal plants for family health care and especially to generate local income. Eco-tourism is the most suggested activity in GWEF for its landscape, history, and functions. Medicinal plant knowledge and home industry wrapped in eco-tourism will become an interesting package of eco-tourism program in GWEF.

Eco-tourism is a type of mechanisms of rewards for environmental services provided by surrounding communities. In eco-tourism program, the agroforestry farmers who cultivate various species of medicinal and agricultural plants are identified as one of environmental services (ES) providers/sellers together with copal collectors, and the rest of surrounding communities. The beneficiaries/buyers of ES are the tourists. The manager of GWEF is the intermediary and with support from NGO and donor bodies, eco-tourism program as mechanism of rewards will benefit surrounding communities, so they will continue providing the ES and at the same time preserving, protecting, and conserving GWEF.

Oral Presentation, 2011 Forest Biodiversity Symposium, Kangwon National University, Chuncheon, Republic of Korea, 10-11 February 2011.

Osaka Gas Foundation of International Cultural Exchange (OGFICE)  funds researches applied by IPB for 2010-2011.  This year’s selected theme is related to development of Energy Independent Village.  There are three topics within this theme, namely:
  1. Utilization of renewable energy to develop Energy Independent Village/Community
  2. Institution, social economy, and/cultural aspects of Energy Independent Village/Community
  3. Biodiversity potential in Energy Independent Village/Community to improve household economy

Theme and topics were selected by PPLH-IPB, as a center that has been mandated to manage OGFICE Research Grant, in order to support development of Energy Independent Village which has become one of Research Agenda in IPB for 2008-2013.  Six proposals from IPB have been approved by the OGFICE, as follow:

  1. Biodiversity of Aquatic Microfungi, Plankton, and Benthos in Ciambulawung River by Hefni Effendi & Aliati Iswantari
  2. Identification of Bioenergy Potential  at Energy Independent Village of Kampung Lebakpicung by Nur R. Rochimawati, Hefni Effendi, & Inna Puspa Ayu
  3. Ethnobotany of Lebakpicung People and Impact of Microhydro Power Plant Introduction to the Utilization of Plant Diversity by Ellyn K. Damayanti & Tovan Yulianto
  4. Techno-Economic Analysis of  Micro hydro at Energy Independent Village of Kampung Lebakpicung, Hegarmanah, Cibeber, Lebak, Banten Province by Y. Aris Purwanto & Nur R. Rochimawati
  5. Documentation & Improvement of Agricultural Practices to Support Sustainable Environment in Lebakpicung Village by Purnama Hidayat & Dina R. Sari
  6. Landscape Ecology Analyses for Water Consumption Mapping on Upland Area of Electric Micro-Hydro Installation (Ciambulawung Watershed), Lebak Picung, Banten Province by Boedi Tjahjono, Kukuh Murtilaksono, & Bambang H. Trisasongko

Research Grant presentation from Executive Director of OGFICE, Mr. Hiroshi Nakajima, to the Rector of IPB, Prof. Herry Suhardiyanto in Rector’s room was held in December 1, 2010.  Before the presentation, six research proposals were presented by the Grantees in PPLH Building and gained positive responses from Mr. Nakajima.  In this occasion, Mr. Nakajima spontaneously offered the second year of grants for the same theme (2011-2012), so that similar researches can be developed into action researches that beneficial for development of Energy Independent Village and especially for the benefit of local people.  This occasion were participated by the grantees (researchers and teams) and closed by lunch gathering.

Until 2010, OGFICE has been in cooperation with IPB for 16 years and funded 76 research titles.  OGFICE support is not only to Indonesia, but also to oil producing countries that products have been bought by Osaka Gas Co.

Melalui program Desa Mandiri Energi Berbasis Mikrohidro berwawasan lingkungan dan pemberdayaan masyarakat, PPLH-IPB telah ikut menggalakkan penanaman pohon di sekitar dan di dalam kawasan Taman Nasional Gunung Halimun Salak (TNGHS).

Sekitar 7000 pohon dari beragam jenis yang telah ditanam disesuaikan dengan peruntukannya, yaitu pohon penghasil buah dan kayu untuk di luar kawasan dan pohon kehutanan untuk di dalam kawasan TNGHS. Penanaman pohon dengan melibatkan masyarakat Kampung Lebakpicung (Desa Hegarmanah, Kec. Cibeber, Kab. Lebak, Prov. Banten) yang berdiam di sekitar taman nasional. Penanaman pohon ini adalah sebagai bagian dari kewajiban masyarakat setelah adanya Pembangkit Tenaga Listrik Mikro Hidro (PLTMH) yang dibangun di Kampung Lebakpicung atas kerjasama CSR PT. PLN Persero (Pusat) dengan PPLH-IPB, dibawah payung kesepakatan bersama antara PLN dengan Departemen Kehutanan.

Meskipun jika dibandingkan dengan luasan Taman Nasional, 7000 pohon bukan jumlah yang banyak, tetapi hal ini setidaknya merupakan wujud dari komitmen civitas IPB dalam mendukung gerakan penanaman pohon dan menjaga Taman Nasional dari kegiatan konversi peruntukkannya.  Luasan total penanaman pohon yang dilakukan secara pengkayaan ini adalah 33 Hektar, yaitu 27 Hektar di lahan masyarakat di luar kawasan TNGHS dan 6 Hektar di dalam kawasan TNGHS.

7000 pohon akan sangat berarti jika kita mengacu bahwa dalam satu hektar ruang terbuka hijau (RTH) yang dipenuhi pohon besar akan menghasilkan 0,6 ton O2 untuk 1.500 penduduk/hari, menyerap 2,5 ton CO2/tahun (6 kg CO2/batang per tahun, menyimpan 900 m3 air tanah/tahun, mentransfer air 4.000 liter/hari, menurunkan suhu 5o C – 8o C, meredam kebisingan 25 – 80 persen dan mengurangi kekuatan angin 75 – 80 persen. Setiap mobil mengeluarkan gas emisi yang dapat diserap oleh 4 pohon dewasa, dengan tinggi 10 m ke atas, diameter batang lebih dari 10 cm, tajuk lebar, berdaun lebat (Joga, 2009). (yap/ekd/tvn)
