Abstract

Degree of electrolyte leakage (EL) from leaf tissue after exposure to high temperature has been used as an indicator of heat tolerance. Inthe present study, EL was measured in an attempt to estimate heat tolerance of Viana umbellata (Thumb.) genotypes at three differentgrowth phases. The degree of heat injury is significantly different among the three growth phases and among the genotypes as well as their interaction. However, the degree of heat injury tends to increase over the plant growth. The 18 genotypes of V. umbellata shows moderate genetic variability as shown by its value of genetic variance (46,25 ±16,35), phenotypic variance (85,37 ±27,60), and coefficientof genetic variation (26,36%).

Abstract

Sengon buto (Enterolobium cyclocarpum Griseb) is one of the potential plant species for land reclamation and possibly for phytoremediation because of its fast growing even on poor soil, and its ability to fertilize soil through nitrogen fixation. For phytoremediation purpose we need fast growing plant with high ability to absorp target contaminant. Fertilization is needed to improve plant growth. This experiment was carried out to study the tolerance of sengon buto (Enterolobium cyclocarpum Griseb) grown on cyanide contaminated tailing media on various level of NPK fertilizer.The sengon buto seed were planted in the tailing of gold mine media mixed with compost (4:1) in pots. Various levels of NPK fertilizer were applied i.e. 0, 2, 4, 6, 8 g/pot at 2 and 2.5 month after planting (MAP).The plant were harvested at 6 MAP. The result showed that NPK fertilizer increase plant growth at level 2 of 2 g/pot, however the value of the increment was not significantly different with control plant (0 g/pot). Cyanide content of NPK treated plants were higher than the untreated plants. The highest value of shoot/root cyanide content ratio was on the NPK untreated plants (4.34) followed by 2 g/pot treatment (3.59). It is means that sengon buto is potential for phytoremediation of tailing of gold mining.

Abstract

Cendana (Santalum album L.) adalah tumbuhan yang memiliki potensi ekonomi tinggi karena penggunaannya di berbagai bidang seperti bahan kosraetika, obat-obatan, kayu ukiran dan bahan kerajinan rumah tangga (home industry). Oleh karena potensinya yang tinggi itu maka eksploitasi dari habitat aslinya dilakukan secara terus-menerus tanpa memperhatikan upaya konservasinya, sehingga populasi cendana dalam habitat aslinya telah sampai pada kondisi yang memprihatinkan. Cendana merupakan salah satu komoditi unggulan di propinsi NTT yang mampu memberikan andil sebesar 22,08% untuk pendapatan asli daerah (PAD). Dalam rangka Otonomisasi Daerah sesuai dengan UU Nomor 22 tahun 1999 maka perhatian khusus untuk konservasi dan pengembangan cendana adalah salah satu prioritas yang tidak dapat dielakkan oleh masyarakat dan PEMDA NTT. Model agroforestry cendana merupakan salah satu pola konservasi dan pengembangan cendana di masa mendatang dengan melibatkan masyarakat lokal untuk menanam cendana di ladang atau tegalannya. Dengan menerapkan pola ini dalam periode jangka panjang (lebih dari 20 tahun) ke depan masyarakat secara berangsur-angsur mengurangi tekanan terhadap pengambilan cendana dari habitat aslinya di alammkarena cendana telah dapat dipanen dari ladang dan tegalannya. Tulisan ini akan membahas pula penyebab kegagalan konservasi cendana, dan beberapa pemikiran tentang kebijakan dasar untuk konservasi cendana pada masa mendatang.

Abstract

Phytoremediation is defined as a clean up of pollutants primarily mediated by pliotosynthetic plants so its could be used as an alternative technique to overcome contaminated soil and water such an mining ecosystems. These plants have several beneficial characteristics; they have ability to accumulate metals in their shoots and especially high tolerance to heavy metals.Since Indonesia has abundant plant diversity, it is believed that some of them are potential to be used as phytoremediator.This research was carried out to study the potential of three species of grasses in accumulating Pb and Cn. The treatments were arranged on Randomized Complete Block Design (factorial design). The first treatment are species of grass: 1) Cynodon dactylon Pers., 2)Cyperus sp. and 3) Ischaemum timorense Kith.; the second treatment is planting media i.e. 1) tailing soil, 2) soil from wildmining (mining activities run by unexpected miners) and 3) top soil and the third is organic fertilizer: 1) manure, 2) compost and 3) no fertilizer.The resultsshowed that all of the three grasses are potential to accumulate Pb and Cn. Organic fertilizer mixed on planting media is significantly affected the growth of grasses and increasing the accumulation of Cn on leaf of Cyperus sp. and I.timorense. While no evidence in increasing Pb accumulation on all of those three grasses species

Abstract

An increasing of population, land conversion, and the behaviour changes in many crops due to global warming could produce a significant negative effect to food security in many countries, including Indonesia. In order to maintain the availability of food, we should find out alternative foods based on corp comodities that can adapt to future agricultural land conditions. One species to be promoted for that purpose is Tacca leontopetaloides (taka). This study was aimed to determine growth characteristics variations of taka in Java and its surrounding small islands through exploration and interview methods. Results indicated that there were two morphological variations of taka based on the canopy colour, namely green and purple. Taka found growing in coastal areas up to100 m above sea level. The light intensity and soil type greatly affected their growth. These plants lived either solitary or in a groups, grow well on sandy soil to clay, under the shade and open areas. Species around taka allegedly contributed in determining taka growth and production. Taka tuber can be an alternative carbohydrate source for supporting food self-sufficiency in coastal communities.
