Kajian Kehadiran Inang Primer pada Pertumbuhan Semai Cendana

Sandalwood  (Santalum album L.)  is known as a fancy plant. Since they have  high economic value, it often over exploited.  As a consequence, the population  dramatically decreased  in their habitats.  Some efforts  have been  done  to conserve  this plant  in order to prevent their extinction, i.e.  seedling multiplication.  As a  hemiparasitic plant,  sandalwoods  need other  plants for a host which grow  around.  Therefore, determining of the the primary host is a necessary aspect in multiplication  of  sandalwood seedling.  This study  used  three  species  plants  to serve sandalwood seedling   as  primary host  in pot cultures consist of local leucaena (Leucaena glauca), vilosa (Acacia villosa)   and calliandra  (Calliandra  calothyrsus).   The results  of this study indicated   that A. vilosa  is better for a primary  host  than  L. glauca and  C. calothyrsus as well. Number of  root connection  between  sandalwood seedlings   and their hosts  have a close correlationship   to  the leaf  number  and the  sandalwood seedling   dry weight, whereas no significant correlationshifp to their height.

Tamarind as tropical plant that grow well in dry land area and savannah. The use of tamarind product have been known as raw material for spices, drinks industries, and medicine, so that this plant is assumed very important for community in dry land area.In Besipae Savannah,South Amanuban,East Nusa Tenggara, tamarind grow wild in savannah and it is one of the sources income forpoeple in that area. During the dry season savannah produce less of fresh forages therefore the fresh leaves of tamarind are used as fodder.The function of cow dung as seed access especially as tamarind, acacias and leucaena seeds were not accomplished yet.The objectives of this study was the viability of tamarind seeds which were collected from cowdung in Besipae Savannah,South Amanuban, East Nusa Tenggara. This study was designed according to factorial model in Completely Rendomized Design(CRD), with four replications.The result of this study indicated that tamarind seeds which were collected from cowdung have higher germinatioan rate and percentage of germination compare to pure seeds from pods.Seedling growth of tamarind seeds which were collected from cowdung were better than that of seedling growth of pure tamarind seeds from pods. Application of cowdung and Bobonaro clay for germination media showed that Bobonaro clay was better than that of cowdung

PENGARUH JUMLAH SEMAI AKASIA (Acacia villosa) DAN LAMTORO LOKAL (Leucaena glauca) SEBAGAI INANG PRIMER CENDANA (Santalum album L.)

Cendana (Santalum album L.) adalah tumbuhan tropik yang bernilai ekonomi tinggi. Cendana diketahui sebagai tumbuhan hemi parasitik, dengan karakter parasit akar. Sebagai tumbuhan hemi parasitik cendana membutuh-kan tumbuhan lain sebagai inangnya. Inang primer dibutuhkan oleh cendana ketika masih hidup dalam bentuk semai di dalam polybag. Beberapa jenis inang primer yang telah dike-tahui adalah akasia (Acacia villosa) dan lam-toro lokal (Leucaena glauca). Tujuan peneliti-an ini adalah menetapkan jumlah inang primer dalam polybag dan membandingkan pengaruh akasia dan lamtoro pada pertumbuhan semai cendana. Penelitian dipolakan mengikuti Ran-cangan Acak Lengkap dengan 3 ulangan. Pene-litian dilakukan di Stasiun Penelitian Kehutan-an cabang Sumba Timur di Hambala, Wainga-pu, Provinsi Nusa Tenggara Timur (NTT). Benih cendana diperoleh dari pulau Timor. Hasil penelitian ini menunjukkan bahwa pengaruh akasia lebih bagus daripada lamtoro lokal sebagai inang primer cendana. Hanya di-butuhkan satu semai sebagai inang primer un-tuk pertumbuhan optimal semai cendana dalam polybag. Penelitian ini memberikan informasi bahwa pertumbuhan lamtoro lebih cepat dari pada pertumbuhan akasia

Intensitas Cahaya pada Perkecambahan Benih dan Pertumbuhan Semai Cabai Merah Landung (Capsicum annuum cv. Landung)

Cabai Merah (Capsicum annuum L.) biasanya ditanam di pembibitan sebelum dipindahkan ke lahan. Informasi mengenai lingkungan optimal, termasuk intensitas cahaya, penting untuk memproduksi bibit cabai berkualitas. Penelitian bertujuan mengetahui pengaruh intensitas cahaya, berdasarkan jenis atap persemaian (paranet kerapatan 25%, 50%, dan 75%, kaca, dan fiberglass), terhadap perkecambahan dan pertumbuhan bibit cabai cv. Landung. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan empat ulangan. Hasil penelitian menunjukkan intensitas cahaya mempengaruhi perkecambahan dan pertumbuhan bibit cabai merah secara keseluruhan. Benih yang memperoleh intensitas cahaya lebih tinggi, yakni di bawah atap kaca (13.876,67 lux) dan atap fiberglass (16.268,89 lux) berkecambah lebih awal dan lebih seragam, dan menghasilkan persentase perkecambahan akhir lebih tinggi (97% dan 95%) dibandingkan benih yang memperoleh intensitas cahaya lebih rendah (atap paranet dengan kerapatan 25%, 50%, dan 75%), masing-masing sebesar 90%, 80,5%, dan 73,2%. Pertumbuhan bibit cabai merah di bawah atap kaca dan fiberglass lebih vigor sehingga menghasilkan kecepatan pertumbuhan (R) lebih tinggi (7,25 dan 7,49) dibandingkan semua perlakuan paranet (7,74, 7,74, dan 7,62). Bahan atap persemaian perlu dipertimbangkan sebab mempengaruhi perkecambahan dan pertumbuhan bibit cabai dengan mempengaruhi intensitas cahaya, seperti ditunjukkan oleh penelitian ini

ZINGIBERACEAE UTILIZATION FROM EAST BANYUMAS PRODUCTION FOREST AS NATURAL EDIBLE ADDITIVES

Benefits of Zingiberaceae family’s plants for rural communities in forest villages are as raw gingery-stuff sources for food additives and health purposes. The superiority of Zingiberaceae’s plants is able to grow well under tree stands and on open sites. Survey on 50 respondents at forest villages under the Forest Management Unity of East Banyumas revealed that those gingery stuffs from eight Zingiberaceae’s plant species (i.e. Alpinia galanga (L.) Willd., Amomum cardamomum Willd., Boesenbergia rotunda (L.) Mansf., Curcumma domestica Val., C. zanthorrhiza Roxb., Etlingera elatior (Jack) R.M.Sm., Kaempferia galanga L. and Zingiber officinale Rosc., have been utilized as edible additives for food and drinks by the community in production forest vicinity. Zingiberaceae-derived additives were categorized as safely consumed for food ingredients/dressings, colorings, aromas, and healthy drinks. Cultivation of Zingiberaceae’s plants could bring economic values and positive impacts to the community and production forest environments. Several Zingiberaceae-derived food ingredients and local drinks have been modified into very-recent recipes, favored for special menus in ISFE’s cuisine-related tourism sites and in modern restaurants. Prospect of Zingiberaceae is expectedly able to develop productive efforts and economies in forest villages; and sustain production forest continually

Keragaman Koleksi Rhododendron dan Tanggapan Bunganya Terhadap Suhu Udara di Sekitarnya Serta Kendala dalam Pengayaan Jenisnya di Kebun Raya Biologi Wamena

Kebun Raya Biologi Wamena (KRBW) merupakan satu - satunya kawasan konservasi ex-situ di ekoregion Papua yang terletak di Kabupaten Jayawijaya. Sebagai kebun koleksi di dataran tinggi, maka dipilihlah marga Rhododendron sebagai salah satu dari beberapa koleksi tumbuhan. Hingga saat ini, KRBW telah mengoleksi 8 jenis Rhododendron, artinya hanya 7,07% dari total jenis Rhododendron yang tersebar di Papua. Dari koleksi ini ditemukan 3 warna bunga yaitu kuning, putih dan ungu. Setiap warna bunga memiliki perbedaan respon terhadap suhu udara di sekitar tumbuhan. Pada penelitian ini didapatkan bahwa pada pagi hari suhu pada mahkota bunga lebih tinggi rata-rata 4,4 - 7,0oC, dibandingkan suhu udara rata-rata 15,72oC, sedangkan pada siang hari suhu pada mahkota bunga lebih rendah. rata-rata 3,6 - 6,0oC dari rata-rata suhu udara 29,9oC. dan juga telah terungkap bahwa pada corolla kuning tersimpan temperatur lebih tinggi daripada temperatur pada corolla putih dan ungu. Beberapa kendala yang dihadapi untuk meningkatkan jumlah jenis Rhododendron di KRBW sebagai berikut; kurangnya kemampuan untuk mengatasi perbedaan suhu antara suhu di habitat Rhododendron terutama di dataran tinggi sekitar 2000 - 3500 m dpl dan suhu udara di KRBW; Belum ada kegiatan khusus untuk mengumpulkan beberapa jenis baru Rhododendron terutama pada beberapa lokasi yang memiliki ketinggian yang sama atau sedikit berbeda dengan KRBW dan kondisi tanah di KRBW yang kurang mendukung pertumbuhan Rhododendron
