Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the important factors affecting productivity of community forests is the use of quality seed. Due to scarcity of seed sources, however, seed quality is not easily available. Currently, community forests serve also as ad hoc seed sources that are usually without appropriate quality assessment. This research was aimed to determine baseline information on spatial variability of mindi fruits collected from five seed sources, and seedling growths treated in seven different growing media consisting mixtures of soil, rice husk, sand and cattle manure. Five mindi populations were selected in the following villages: Nagrak (Bogor), Babakan Rema (Kuningan), Padasari (Sumedang), Sukakarya (Bogor) and Gambung (Bandung). The results showed that variability of seed dimension (CV=4.82-14.37%) and seedling growth (11.79-21.77%) were moderate. The mindi fruits from Nagrak were found to be the biggest in terms of size (1.22 ± 0.17 cm), weight (0.40 ± 0.04 g), and seed set (85.47 ± 15.09%). In addition, the seedling growth from Nagrak was also better than those of other villages showing its potential for future seed sources. Growing media containing cattle manure were observed consistently to be the best for seedling growth. The findings are useful in supporting scientifically the selection of seed sources from community forests.

Abstract

Sukun (Artocarpus altilis Parkinson ex F.A.Zorn) yang ada di Indonesia umumnya adalah tanpa biji. Sehingga sangat sulit untuk dikembangkan secara generatif dengan biji. Alternatifnya adalah dengan perkembangbiakan secara vegetatif dengan setek. Faktor penting untuk menjamin kelangsungan hidup suatu setek adalah pembentukan tunas dan akar yang dapat dirangsang dengan zat pengatur tumbuh (ZPT). Salah satu ZPT alami yang dapat digunakan utuk merangsang pertumbuhan akar dan setek adalah ekstrak bawang merah. Penelitian ini adalah untuk mengetahui lama perendaman ekstrak bawang merah terhadap pertumbuhan akar dan tunas setek batang sukun Pengambilan bahan setek sukun dilakukan di kawasan Desa Madapolo, Kecamatan Obi, Kabupaten Halmahera Selatan, Provinsi Maluku Utara. Perlakuan yang diterapkan adalah perbedaan lama perendaman bahan setek batang sukun ke dalam larutan ekstrak bawang merah. Lama perendaman yang diterapkan sebanyak 4 perlakuan, yaitu: 0 menit (kontrol), 10 menit, 20 menit, dan 30 menit. Pengamatan pertumbuhan tunas setek dilakukan selama 12 minggu dan pengamatan akar dilakukan pada akhir pengamatan. Hasil pengamatan menunjukkan bahwa lama perendaman ZPT alami ekstrak  bawang merah berpengaruh terhadap pertumbuhan tunas dan akar setek. Jumlah tunas terbanyak pada perlakuan tanpa perendaman ekstrak bawang merah, sedangkan panjang tunas yang tertinggi adalah pada perlakuan perendaman ekstrak bawang merah selama 30 menit, demikian pula untuk jumlah dan panjang akar.

Abstract

Kualitas media berpengaruh terhadap terhadap pertumbuhan tanaman karena dalam media tanam terdapat unsur hara yang mendukung pertumbuhan. Komposisi media tanam yang berbeda diduga juga memberikan pengaruh yang berbeda terhadap pertumbuhan. Penelitian ini bertujuan untuk mengidentifikasi respon pertumbuhan bibit jabon merah pada komposisi media tanam yang berbeda. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan perbedaan komposisi media tanam (M1:tanah, M2:tanah dan pasir, M3:tanah, pasir dan kompos, dan M4:tanah, pasir dan pupuk kandang). Variabel pertumbuhan bibit yang diamati adalah tinggi bibit, diameter bibit, jumlah dan luas daun. Adapun parameter pertumbuhan bibit yaitu Nisbah Pucuk Akar (NPA) dan Indeks Mutu Bibit (IMB). Hasil penelitian menunjukkan bahwa media M4 memberikan pertumbuhan yang lebih besar pada tinggi bibit, diameter bibit, jumlah dan luas daun. Adapun M3 memberikan nilai NPA dan IMB yang lebih tinggi. Perbedaan komposisi media tanam berpengaruh nyata pada variabel pertumbuhan luas daun. Komposisi media tanam terbaik untuk pertumbuhan bibit jabon merah yang optimal adalah M4 (tanah, pasir, dan pupuk kandang dengan perbandingan 3:2:1).

Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the factors that affect productivity of mindi plantation is high quality seed that is not easily available. Seed sources of mindi should be established based on the status of genetic variation, preferably the one with high genetic variation. However, information on the status of genetic variation is always lacking. The research objective was to estimate genetic variation within and between populations of mindi in West Java community forests based on microsatellites. Six mindi populations were selected in the following villages: Nagrak (Bogor),Babakan Rema (Kuningan), Padasari (Sumedang), Legok Huni (Wanayasa), Sukakarya (Bogor) and Gambung (Bandung).The results showed that average number of alleles was 2.750, PLP (percentage of polymorphic loci) was 91.67%, and the genetic diversity within populations (He) was 0.366. The highest genetic diversity was found in Padasari (He = 0.454), and the lowest one was in Babakan Rema (He = 0.269). The genetic difference between populations (Fst) was 0.3030. Cluster analysis showed three groupings in which the first and second clusterconsisted of Nagrak and Padasari, as well as Babakan Rema, Gambung and Sukakarya, respectively. On the other hand Legok Huni was separated alone. The findings provided information on the moderate status of genetic diversity that may be considered during the selection and establishment of seed sources.Key words : community forests, genetic diversity microsatellite, mindi (Melia azedarach L.)

Abstract

Mangrove ecosystems have a very important role for the coastal environment, both in terms of physical, ecological and economic. One of the important mangrove areas in South Halmahera is on the coast of Pogo-Pogo island. The purpose of this study was to identify the diversity and dominance of mangrove species in the Pogo-Pogo Strait. Research uses the method of the plot lanes. The types of mangroves found in the research location were 9 species, 3 of which were categorized as true mangrove and 6 types of asociate mangrove. The diversity of mangroves found at the study site was relatively low. The Shannon-Wienner species diversity index (H ') for seedling (H' = 0.59), sapling (H '= 0.00), and tree (H' = 0.66). This indicates that the distribution of individual numbers of each species was lowed and the stability of the mangrove forest community in the Pogo-Pogo strait was lowed. In all level of growth (seedlings, saplings and trees), the Rhizophora mucronata was the most dominating species.Key words: mangrove, diversity, pogo-pogo

Abstract

The development of nutmeg (Myristica fragrans Houtt) community forests needs to be supported by high-quality seed procurement, both physical, physiological, and genetic quality. Physically it can be done by morphological analysis in the form of length, diameter, and weight of seeds. Meanwhile, to determine the physiological quality, one of which is by observing germination. This research aimed to identify the morphology of seeds and germination of nutmeg (M. fragrans Houtt.) from different seed sources in the development of nutmeg community forests in Bacan, South Halmahera. The results showed that the morphology of nutmeg seeds in the shape, color, and skin surface variables at the three locations (Amasing, Papaloang, and Babang) obtained the same results, namely oval, brownish-black and shiny. Whereas in seed length, nutmeg from Papaloang has a longer seed size than seeds from Amasing and Babang. In the germination parameter values, seeds from Papaloang were found to have the highest value, namely the percentage of germination (K = 35%), peak value (PV = 0.56), average daily germination (MDG = 0.56), germination value (NK = 0.31 ).
