Abstract

 ABSTRAK Tujuan penelitian ini adalah untuk memperoleh data dan informasi tentang besarnya pengaruh pembebasan jenis Acacia nilotica (L.)Willd.ex Del di Taman Nasional Baluran terhadap komposisi jenis tumbuhan penyusun savana dan kualitas dari savana yang ada. Metode yang digunakan adalah metode analisis vegetasi dengan  ukuran  petak  minimum  ditentukan  menggunakan  kurva  spesies  area.  Hasil  penelitian  ini menunjukkan bahwa komposisi jenis penyusun antara savana terbebas dari invasi dan savana terinvasi A. nilotica adalah berbeda. Komposisi jenis pada savana terbebas dari invasi terdiri dari 38 jenis terdiri dari jenis rumput, semak belukar, dan permudaan alam jenis pohon. Komposisi jenis penyusun savana yang terinvasi adalah 13 jenis terdiri dari 2 jenis rumput dan 11 jenis bukan rumput. Nilai indeks kesamaan komunitas adalah 38,38% sehingga kedua komunitas ini  berbeda. Indeks dominansi pada savana  yang terinvasi lebih tinggi daripada savana yang terehabilitasi, tetapi nilai indeks keragaman tertinggi pada savana yang terbebas dari invasi sebesar 1,216 sehingga pada komunitas ini lebih mantap dibandingkan dengan savana yang terinvasi jenis A. nilotica. Potensi biomassa pada areal savana terbebas dari invasi A. nilotica berkisar antara 1.067,5 kg/ha –  2.756,25 kg/ha lebih besar dari savana  yang terinvasi dengan potensi biomassanya antara 422,5 kg/ha– 1.000 kg/ha.

Abstract

ABSTRAK Padang  rumput  mempunyai  fungsi  sebagai  tempat  penyedia  makanan  bagi  hewan,  terutama  mamalia herbivora besar, dan pusat aktivitas hewan seperti kawin, mengasuh, dan membesarkan anaknya, serta interaksi sosial lainnya. Selain itu, padang rumput juga merupakan habitat dari berbagai jenis tumbuhan yang berfungsi sebagai pestisida alami. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman jenis tumbuhan yang berfungsi sebagai pestisida alami di areal savana Bekol Taman Nasional Baluran. Pengambilan data  lapangan dilakukan dengan penentuan ukuran petak contoh, penentuan jumlah petak contoh serta analisis data kuantitatif yang meliputi kerapatan, frekuensi, dan Indeks Nilai Penting (INP). Hasil penelitian menunjukkan bahwa, terdapat tujuh spesies yang berfungsi sebagai pestisida alami dari 38 spesies tumbuhan yang ditemui di savana Bekol.  Ini berarti bahwa, 18% dari total jenis tumbuhan yang ada berfungsi sebagai pestisida alami.

Abstract

Conservation and development of non-timber forest product (NTFPs) commodities in East Nusa Tenggara (NTT) are urgently needed. NTFPs are a source of livelihood for the rural communities around the forest areas. NTFPs development around the forest areas is needed as a means to create livelihoods and reduce poverty. The management strategy for forest areas based on integrating conservation and community welfare improvement is needed. The research aims to determine the NTFPs potency in Sikka Regency and the socio-economic conditions of NTFP farmers and to initiate the conservation and development of NTFPs based on the agroforestry approach. The research was conducted through literature review, secondary and primary data collection through surveys, interviews and field observations. The results of the study showed that tamarind (Tamarindus indica L.), candlenut (Aleurites moluccana (L) Willd.), areca nut (Areca cathecu L.), and betel (Piper betle L.) is the major of NTFP commodities in Sikka district. The socio-economic conditions of NTFP farmers on surrounding farmer are not prosperous yet, and highly depend on the sustainability of NTFP production. Community initiatives to conserve and regenerate NTFPs through agroforestry need to be improved, especially in improving the rate of plant growth. Technical assistance to increase community capacity in conservation and development of NTFPs around forest areas and private land is still needed.

Abstract

Cardamom (Amomum cardamomum), the ‘Queen of spices’, is a native Indonesian spice, a type of potential biopharmaceutical currently prospective because of its high selling value, especially for its fruit, with various benefits and its wide use. So far, cardamom essential oil comes from the utilization of its fruit, but the production is more limited, unlike the sustainably produced leaves, therefore, its leaves have the potential to be developed. This study aims to analyze the essential oil yield and 1.8-cineol content of cardamom leaves essential oil (CLEO) grown in agroforestry systems. The CLEO was obtained by steam-water distillation, while the 1.8-cineol content was analyzed by gas chromatography–mass spectrometry (GC-MS). The experimental design employed was a Randomized Complete Block Design with three cropping patterns as a treatment and three doses of bokashi fertilizer as blocks. The results showed that the highest yield of CLEO was generated in the sengon + cardamom agroforestry pattern of 3.16%, and the highest content of 1,8-cineol in CLEO was generated in the sengon + cardamom + arrowroot agroforestry pattern of 47.23%, while the lowest yield of CLEO and the 1,8-cineol content were found in the monoculture pattern of 2,02% and 43.16% respectively. Agroforestry practices have the potential to increase 1,8-cineol content and the yield of essential oil in cardamom leaf, which will be prospective in forest management to support forestry multi-business and social forestry programs.
