KEBUN RAYA INDROKILO BOYOLALI: KONSERVASI EX-SITU HUTAN HUJAN DATARAN RENDAH JAWA BAGIAN TIMUR
Get PDFIt just took four years for Indrokilo Boyolali Botanical Garden (KRIB) from the initiation to its launching, making it as one of botanical gardens in Indonesia with the fastest development. Despite the young age and the small extent of the garden with only 9,35 ha, KRIB has played the five roles of botanical garden, namely conservation ex-situ, research, education, tourism and ecosystem services. Currently, the garden has 1368 specimens of plant collection belong to 81 families, 196 genera, 278 spesies and 215 of the specimens are still unidentified. Many facilities and point of interests have been built in the garden, among them are the iconic Pasingsingan gate, Mahesa Jenar statue and the replicas of Noah Arch and Niagara waterfall. More than 38.000 visitors have visited KRIB in 2019 alone with some of them are for school excursion and teaching purposes. Two lessons learned from the success story of KRIB when developing a new botanic garden are the high level of commitment by the top leader manifested in budget and institutional policy supports, and the strategic location and ease of accessibility of the garden
PENGARUH JENIS EKSPLAN DAN KOMBINASI ZAT PENGATUR TUMBUH (ZPT) TERHADAP INDUKSI KALUS Begonia bimaensis Undaharta & Ardaka SECARA IN VITRO
Get PDFBegonia bimaensis Undaharta & Ardaka is a potential ornamental plant, and currently known only from one population in Sumbawa. Propagation programs, both conventional and in vitro culture are necessary to ensure its conservation. The aim of this research is to observe the effects of explant types and plant growth regulator combination (2,4-D and kinetin) in inducing callus from B. bimaensis leaf in vitro. Callus induction was initiated from three parts of leaf explant, namely petiole, leaf base, and leaf lamina. The explants were planted on Murashige & Skoog (MS) medium with addition of 2,4-D and kinetin. Concentrations of 2,4-D were 0, 0.5, and 1 ppm, while kinetin concentrations were 0, 1, and 2 ppm. Each treatment was replicated 10 times. Results showed that leaf base was the best explant used for callus induction. Medium D1K2 (MS + 1 ppm kinetin) showed the fastest time for callus induction that was at 20 days after planting. The highest percentage of callus production (100%) was found on D1K3 (MS + 2ppm kinetin); D2K2 (MS + 0.5ppm 2,4-D + 1 ppm kinetin); D2K3 (MS + 0.5ppm 2,4-D + 2ppm kinetin) and D3K2 (MS + 1ppm 2,4-D + 1ppm kinetin).Begonia bimaensis Undaharta & Ardaka merupakan tumbuhan berpotensi hias yang tergolong endemik, hingga saat ini diketahui dari satu populasi saja di Sumbawa. Oleh karena itu perlu dilakukan upaya perbanyakan untuk mencegah jenis ini dari kepunahan. Perbanyakan in vitro melalui induksi kalus memiliki keuntungan karena dapat menghasilkan bibit tanaman dalam jumlah banyak dalam waktu relatif singkat. Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis eksplan dan kombinasi ZPT (2,4-D dan kinetin) dalam menginduksi kalus pada daun B. bimaensis secara in vitro. Induksi kalus B. bimaensis diinisiasi dari eksplan daun yang dibagi menjadi tiga bagian yaitu: tangkai daun, pangkal daun, dan helaian daun. Ketiga jenis eksplan ditanam pada media induksi kalus menggunakan media dasar Murashige & Skoog (MS) dengan penambahan zat pengatur tumbuh (ZPT) 2,4-D dan kinetin. Konsentrasi 2,4-D yang digunakan adalah 0, 0,5, dan 1 ppm. Sedangkan konsentrasi kinetin sebesar 0, 1, dan 2 ppm. Setiap perlakuan diulang sebanyak 10 kali. Hasil penelitian menunjukkan bahwa eksplan pangkal daun paling baik dalam menginduksi kalus. Kombinasi media yang paling cepat dalam menginduksi kalus pada 20 HST adalah D1K2 (MS + 1ppm kinetin). Sedangkan kombinasi media yang paling tinggi dalam menghasilkan persentase eksplan berkalus yaitu: D1K3 (MS + 2ppm kinetin); D2K2 (MS + 0.5ppm 2,4-D + 1 ppm kinetin); D2K3 (MS + 0.5ppm 2,4-D + 2ppm kinetin) dan D3K2 (MS + 1ppm 2,4-D + 1ppm kinetin) sebesar 100%
KOLEKSI TUMBUHAN TERANCAM DI KEBUN RAYA CIBODAS DARI HASIL EKSPLORASI TAHUN 2015-2017 DI BENGKULU DAN LAMPUNG (SUMATRA)
No full textThe living collection of Indonesian Botanic Gardens mainly derived from its native habitat accross Indonesian Archipelago. Over the years, native western Indonesian flora have been cultivated in Cibodas Botanic Gardens, a mountaineous site for plant from higher altitude of origin. During 2015-2017 flora exploration program were focused in 3 conservation areas in two province of Sumatra Bengkulu and Lampung. Each site is Gunung Seblat National Park and Bukit Raje Mandare surround Gunung Patah in Bengkulu, other is Tanggamus protected forest in Lampung. There are 2 threatened plants listed in IUCN red list coming from this exploration namely Castanopsis tungurut (Blume) A.DC and Lithocarpus indutus (Bl) Rehd.The living collection of Indonesian Botanic Gardens mainly derived from its native habitat accross Indonesian Archipelago.

EVALUASI KESUBURAN TANAH PADA BERBAGAI TUTUPAN LAHAN DI KEBUN RAYA BOGOR
Get PDFBogor Botanic Gardens (BBG), which one of the oldest Botanic Garden in Southeast Asia has more than 12.000 specimen of plants collections. The state soil fertility management is essential for collection in BBG, but currently the soil fertility in BBG unknown. This study aims to evaluate soil fertility condition with analysis of soil chemical and physical properties. Expected to a consideration in the collection management fertility herbs optimal expected to grow. The study conducted in March–October 2019. Methods used is land survey detail (1:5,000–1:10,000 of scales) to a special purpose fertility land the chemistry and physics properties. The sampling location determined by overlaying map of the garden, land cover (grass, litter, and without litter) and contour. The soil samples are collected using the sample ring and disturbed soil method. Variables were observed consisting of texture, pH, cation exchange capacity, total nitrogen, P2O5 available, K2O available, and C organic. The results showed soil fertility class in BBG had low until medium fertility (94,07 %) at various type of land cover. Covers litter having soil fertility higher compared to others (45,32%) (low–medium category). Advice that can be recommended is the litter zoning management, litter so that the process of decomposing organic cycle runs covered.Kebun Raya Bogor (KRB) merupakan salah satu kebun raya tertua di Asia Tenggara yang memiliki jumlah koleksi tumbuhan mencapai lebih dari 12.000 spesimen. Kondisi kesuburan tanah sangat penting untuk pengelolaan koleksi di KRB, namun saat ini kondisi kesuburan tanah di KRB belum diketahui. Tujuan penelitian ini adalah untuk mengetahui kondisi kesuburan tanah, meliputi sifat kimia dan fisika tanah. Diharapkan dapat menjadi bahan pertimbangan dalam manajemen kesuburan tanah sehingga tumbuhan koleksi dapat tumbuh dengan optimal. Penelitian dilaksanakan pada bulan Maret–Oktober 2019. Metode yang digunakan adalah survei tanah detail (skala 1:5.000–1:10.000) dengan tujuan khusus yaitu kesuburan kimia dan fisika tanah. Pengambilan sampel berdasarkan overlay dari peta kebun, tutupan lahan (rumput; serasah, dan tanpa serasah) dan kontur. Sampel yang diambil dengan metode ring sampel dan tanah terganggu. Variabel pengamatannya mencakup tekstur, pH, kapasitas tukar kation, nitrogen total, P2O5 tersedia, K2O tersedia, dan C organik. Hasil penelitian menunjukkan bahwa kondisi kesuburan tanah di KRB cenderung rendah hingga sedang (94,07%) pada berbagai tipe tutupan lahan. Tutupan serasah memiliki kesuburan tanah lebih tinggi dibandingkan lainnya (45,32%) (kategori rendah–sedang). Saran yang dapat direkomendasikan adalah pengelolaan zonasi serasah, sehingga proses dekomposisi berjalan dengan siklus hara tertutup
