Abstract

Tujuan dari penelitian ini adalah untuk mengkaji keanekaragaman Fungi Mikoriza Arbuskula (FMA) pada rizosfer jernang di Jambi. Teknik pengambilan sampel tanah dan akar dilakukan dengan metode proporsional. Pengambilan sampel tanah dilakukan secara komposit pada kedalaman 0-20 cm dan 20-40 cm, contoh tanah diambil dari rizosfer jernang sebanyak 500 g pada setiap batang. Spora diisolasi dengan tehnik tuang saring basah dan dilanjutkan dengan sentifugasi, lalu kepadatan sporanya diukur dan diidentifikasi. Hasil identifikasi menunjukkan rata-rata jumlah spora adalah 106,39-209,46 spora per 20 g tanah. Kolonisasi akar berada pada kisaran 39,25%-64,25%. Keanekaragaman FMA menunjukkan 48 tipe spora FMA yang terdiri dari 31 tipe Glomus, 9 tipe Acaulospora, 7 tipe Scutellospora, dan 1 tipe Gigaspora. Glomus memiliki tingkat penyebaran tertinggi di masing-masing kedalaman. Kelimpahan relatif Glomus di kedua kedalaman sebesar 100 %. Frekuensi relatif pada Glomus juga mendominasi pada kedalaman tanah 0-20 cm sebesar 92,27%, dan tanah pada kedalaman 20-40 cm sebesar 95,05%. Kata kunci: FMA, Daemonorops draco Blume, Jambi

Abstract

Jernang rattan is produced from a palm species surface layer of fruit by resine with dark red. Jernang rattan cultivation has several obstacles due to limiteation of seed availability, low seed production, recalcitrant seeds, and slow seedling growth. In order to accelerate seedling growth and providing a good quality of seedlings, an inoculation of seedling with Arbuscular Mycorrhizal Fungi (AMF) and addition of bio-organics in growing media is needed. This study aimed to analyze the growth responses of Daemonorops draco Blume seedlings inoculated by AMF and addition of bio-organic. The research design used was completely randomized design which consists of two factors, AMF (M) consists of four levels (M0 = Without AMF, M1= AMF collection in the mycorrhizal laboratory M2= Indigenous FMA from rattan rhizosphere and bio-organic (B) consisting of five levels (B0= Without bio-organic, B1= dose of bio-organic 5%, B2= dose of bio-organic 10%, B3= dose of bio-organic 15%, B4= dose of bio-organic 20%). The results showed that control soil media could not to support the growth of Rattan Jernang Seedlings. The plant treated by interaction (M2B2) increased plant height by 140.76%, diameter by 106.57% and biomass by 591.22% compared with control.

Abstract

Jernang rattan is produced from a palm species surface layer of fruit by resine with dark red. Jernang rattan cultivation has several obstacles due to limiteation of seed availability, low seed production, and has technical problems in the form of hard fruit skin. This study aimed to studied the effect of the interaction of atonic concentration and soaking time for jernang rattan seeds on their germination. There were two factors in this study: Atonic concentration treatment (5 levels) and soaking time (3 levels). The results show that increasing the germination of Jernang rattan seeds can be done using an atonic concentration of 15 ppm and soaking for 1 hour. This is because it provides better results on research variables.

Abstract

Harimau Sumatera (Panthera tigris sumatrae) satwa dilindungi menurut UU No 5 tahun 1990 tentang Konservasi Sumber Daya Alam Hayati dan Ekosistemnya dan dalam Peraturan Pemerintah yaitu PP No 7 tahun 1999 tentang Pengawetan Tumbuhan dan Satwa. Ancaman kepunahan harimau sumatera pada kategori kritis, namun informasi mengenai dinamika populasinya di ekosistem spesifik lahan basah. Taman Nasional Berbak dan Sembilang yang menjadi salah satu Kawasan konservasi yang melakukan pemantauan satwa ini secara intensif. Penelitian ini bertujuan untuk memetakan sebaran populasi melalui analisis kelimpahan relatif dan tingkat hunian (occupancy) di kawasan tiger core area, Taman Nasional Berbak dan Sembilang. Menggunakan data dari 50 titik kamera pengintai (camera trap), penelitian ini mengevaluasi keberadaan harimau sumatera berdasarkan intensitas pergerakan dan preferensi habitat yang dipilih sebagai hunian. Hasil penelitian menunjukkan nilai indeks kelimpahan relatif sebesar 6,4 foto per 100 hari, dengan tingkat hunian mencapai 33%. Analisis data mengidentifikasi bahwa jarak dari sungai merupakan faktor lingkungan paling dominan (97%) yang mempengaruhi keberadaan harimau sumatera di wilayah penelitian. Temuan ini memberikan implikasi penting bagi pengelola kawasan untuk memprioritaskan perlindungan ekosistem sempadan sungai sebagai jalur pergerakan utama dan habitat kunci dalam upaya konservasi harimau sumatera.

Abstract

Sungai Cemara Village, located in Tanjung Jabung Timur Regency, Jambi Province, is part of the East Coast Mangrove Forest Nature Reserve and directly borders Berbak Sembilang National Park. This area encompasses approximately 300 hectares of mangrove ecosystems that play a crucial role in coastal protection and serve as habitat for various wildlife species, including migratory birds and the Sumatran tiger. This study aims to analyze the vegetation structure and habitat characteristics of the mangrove ecosystem in the region. The research employed a vegetation survey method across five transects comprising a total of 100 plots, covering three growth stages: seedlings, saplings, and mature trees. The results showed that Avicennia sp. was the dominant species with the highest Important Value Index (IVI) across all growth stages—1.31% in seedlings, 1.34% in saplings, and 1.48% in mature trees. Environmental parameters indicated favorable conditions for mangrove growth, with temperatures ranging from 28–30°C, salinity between 23–25 ppt, soil and water pH values between 6 and 7, and predominantly muddy substrates. These findings suggest that the mangrove ecosystem in Sungai Cemara Village is in a good regenerative condition and holds strong potential for ecologically based conservation efforts.
