Abstract

The Kutai National Park (KNP) which is located in East Kutai Regency on East Kalimantan Province is endowed with numerous pristine of mangrove forest. However, related information to the species composition and diversity of KNP mangrove is still scanty. Twenty-one of mangrove species were recorded using the quadratic transects survey method (total plot area of 1.7 ha). Main species of mangrove communities were Avicennia lanata, A. marina, Bruguiera gymnorrhysa, B sexangular, Ceriops tagal, Rhizophora apiculata, R. mucronata and Sonneratia Alba. Mangrove density was recorded reached as 1,699 trees ha-1, saplings of 4,395 ha-1 and seedlings 25,348 ha-1. Significant tree density was found in Pandan Bay Estuary. While in the Lombok Bay and the Kaba Bay significant for sapling and seedling categories. Importance value index of mangrove species in the three study locations for three growth categories (tree, sapling and seedling) showed significant differences (p-value> α0.05). Mangrove stand at three study locations has almost the same characteristics. The species diversity and evenness index has shown the same distribution pattern. The findings of this study suggest that KNP mangrove forest stand is not heavily damaged even though there is a lot of human activity. This mangrove could be managed and conserved for multi-sectoral purposes such as ecotourism, research, biodiversity and education rather than solely as a Nature Conservation Area.

Abstract

Pengelolaan sumberdaya alam dalam kawasan taman nasional tidak hanya cukup menyandarkan pada pendekatan teknis, tetapi bagaimana merumuskan dan menyusun kebijakan yang lebih terpadu (komprehensif), interdisiplin, dan berbasiskan kemampuan sumberdaya lokal dengan melibatkan semua stakeholder yang berkepentingan atas sumberdaya alam tersebut. Penelitian ini bertujuan untuk mendapatkan data dan penjelasan peluang diakomodasinya kepentingan masyarakat untuk meremajakan tanaman kemiri dalam kawasan Taman Nasional Bantimurung Bulusaraung (TN Babul) sesuai dengan peraturan yang berlaku. Penelitian ini dilaksanakan di Kabupaten Maros pada Kawasan TN Babul, Provinsi Sulawesi Selatan. Pengumpulan data dilakukan melalui studi dokumentasi dan wawancara kepada sejumlah informan kunci. Data dianalisis dengan teknik analisis isi (content analysis ) dan analisis deskriptif kualitatif. Hasil penelitian menunjukkan bahwa keinginan masyarakat untuk meremajakan tanaman kemiri dalam kawasan TN Babul sulit diakomodasi. Hal ini disebabkan oleh ketidak-konsistenan diantara kebijakan pemerintah yang ada (UU No. 5/1990, PP No. 28/2011 dan Permenhut No. P.56/2006). Untuk itu diperlukan revisi-revisi sehingga dapat diimplementasikan pada berbagai kondisi yang berbeda-beda.

Abstract

The urbanization rate may give an adverse effect on a city. For example, it accrues the number of urban dwellers and induces the exploitation of land resources with a quick conversion rate, which leads to the degradation of the quality of the environment. This condition is exacerbated by deescalated green and open spaces (RTH) as a CO2 absorber. CO2 emissions in urban regions can be mitigated by exerting trees, which have a pivotal role in carbon uptake. This research imparts an analysis of plant species that are potential for absorbing carbon and storing biomass in green and open spaces in Ambon. The research method is quantitative by estimating biomass and carbon uptake of trees. Results indicate that trembesi (Samanea saman), linggua (Pterocarpus indicus), mahoni (Swietenia macrophylla), bintanggur (Calophyllum inophyllum), and kerai payung (Filicium decipiens) are typical trees planted in Ambon. The highest CO2 uptake capacity (B = 110.95 tons/ha, CO2 = 191.38 tons/ha) is identified in Trembesi (Samanea Saman), linggua (Pterocarpus indicus), the second-highest with a B = 61.66 tons/ha and CO2 = 106.36 tons/ha, and Akasia (Acacia mangium), the third-highest with a B = 25.24 tons/ha and CO2 = 41.69 tons/ha

Abstract

Agroforestry system as well as the potential species and the corresponding economic valuesin Ciamis District are very diverse. To encourage farmers adopt agroforestry system, botheconomical and environmental advantages have to be promoted.  This research wasconducted at April to July 2010 at Ciomas, Kalijaya and Kertaharja villages in the Panjalu,Banjarsari, and Cimerak sub-Districts respectively.  Primary and secondary data wereanalyzed by quantitative and qualitative descriptive.  The result showed that the highertopography, the more simple agroforestry system applied.  The narrower forest size managed(strata 3), the higher chance agroforestry system adopted by farmers.  Farmers in the highand low topography (Northern and Southern Ciamis regions) had higher chance to adoptagroforestry system, while the moderate topography showed lower adoption chance.  Theeconomic contribution of non-forest products (NFPs) influences strongly the farmer decisionto adopt agroforestry system. The highest economic contribution of Paraserienthesmoluccana was 42.71% in Kalijaya, while the highest economic contribution of non-forestproduct was 75.00 % in Ciomas.
