Abstract

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.

Abstract

Penyimpanan benih dalam jangka waktu tertentu dapat memengaruhi viabilitas benih. Tujuan penelitian ini adalah menganalisis pengaruh lama penyimpanan benih terhadap viabilitas benih mindi. Metode yang digunakan adalah uji daya hantar listrik atau electrical conductivity (EC) terhadap air rendaman benih yang telah disimpan selama 0, 2, 4, 6, dan 8 bulan. Pengukuran nilai konduktivitas listrik dilakukan menggunakan alat conductivity meter. Hasil penelitian menunjukkan bahwa lama penyimpanan memengaruhi nilai EC benih mindi. Nilai EC terendah adalah 15,63 µS/cm pada penyimpanan 0 bulan dan nilai EC tertinggi adalah 31,87 µS/cm pada penyimpanan 8 bulan. Lama penyimpanan memiliki korelasi positif terhadap nilai EC sebesar 0,75. Nilai EC yang tinggi menunjukkan banyaknya perembesan cairan sel yang keluar dari benih sehingga menurunkan kapasitas perkecambahan benihnya. Nilai EC memiliki korelasi negatif terhadap viabilitas benih. Secara umum, semakin lama benih disimpan, maka viabilitas benih semakin menurun.

Abstract

Pemanfaatan lahan pascatambang dilakukan melalui kegiatan revegetasi atau rehabilitasi yang bertujuan untuk memulihkan kondisi ekologi dan memperbaiki kondisi lingkungan. Proses rehabilitasi ini melibatkan penggunaan bahan organik dengan menggunakan pot organik dan penambahan FMA guna memperbaiki lahan yang terdampak aktivitas penambangan, sekaligus pemilihan tanaman yang sesuai dengan kondisi lahan tersebut. Penelitian ini bertujuan untuk mengetahui kemampuan dan komposisi pot organik terbaik untuk pertumbuhan bibit mahoni pada media pascatambang dan mengevaluasi kompatibilitas pot organik dengan FMA dalam meningkatkan pertumbuhan tanaman mahoni pada media tanah pascatambang. Untuk mencapai tujuan tersebut, dilakukan pengujian daya serap pot organik, kekakuan lentur dan kekuatan lentur dengan menggunakan rancangan acak lengkap (RAL) yang terdiri dari tiga komposisi pot organik dan masing-masing satuan percobaan terdapat tiga ulangan. Pengujian pot organik terhadap pertumbuhan bibit mahoni menggunakan split plot yang terdiri atas perlakuan inokulasi FMA sebagai petak utama dan komposisi pot organik sebagai anak petak. Penggunaan pot organik dengan komposisi RT1 yang dikombinasikan dengan inokulasi FMA terbukti memberikan hasil terbaik terhadap pertumbuhan bibit mahoni pada media tanah pascatambang. Kombinasi tersebut mampu meningkatkan tinggi tanaman, biomassa, kolonisasi akar, serta nisbah pucuk akar secara signifikan. Penggunaan pot organik dan FMA merupakan metode inovatif dan ramah lingkungan untuk mendukung revegetasi lahan pascatambang.

Abstract

Open-pit coal mining activities have an impact on environmental changes, one of which is the emergence of acid mine drainage. Acid mine drainage (AMD) arises from sulfide minerals that react with oxygen and water. Coal utilized in electric steam power plants as fuel to produce electrical energy results in combustion residue known as fly ash and bottom ash (FABA). FABA has alkaline properties and has the potential to be combined with plant species that are resistant to acid mine drainage (AMD). This study aimed to explore the potential use of FABA as a growing medium for eucalyptus (Melaleuca cajuputi) to neutralize the pH of acid mine drainage (AMD) in artificial wetlands. FABA block medium was made by mixing FABA, cow manure, and cement as an adhesive and incorporating holes as planting media. The results of this study showed that the application of FABA and cow manure increased the pH of AMD from 3.27 to 6.27 in 24 hours. FABA medium blocks could adsorb heavy metals in AMD, such as Fe in the K1-P1 treatment, from a value of 0.15 mg/L to 0.08 mg/L, and heavy metal Mn in the K3-P3 treatment, from a value of 4.1 mg/L to 0.2 mg/L. In addition, medium blocks K2 (50% FABA + 30% cow manure + 20% cement) and K3 (30% FABA + 50% cow manure + 20% cement) had a good effect on the growth of M. cajuputi seedlings in the K3-P1 treatment with an average height of 17.67 cm and a stem diameter of 9.2 mm for 8 weeks.

Abstract

In vitro continuous development (proliferation) and growth enhancement of callus, which orginated from irradiated-plantlets of Solomon teak clones, have been sequentially conducted on culture medium of (1) MS + 0.1 ppm kinetin, then transferred to (2) an half-strength MS + 0.1 ppm kinetin + 0.1 ppm BAP + 100 ppm charcoal, to (3) an half-strength MS + 0.1 ppm BAP + 3% sugar and finally to (4) half strength MS + 0.3 ppm BAP + 3% sugar. The objectives of this research were to evaluate the morphogenesis of putative-mutant Solomon teak from generation M1V1 and estimate allele frequencies as well as population heterozygosity in vitro.  Results demonstrated that exposure to gamma irradiation (10, 20, 30, and 40 Gy) in the M1V1 generation induced callus formation within two weeks, followed by the development of embryogenic callus. Genetic analysis revealed low diversity among M1V1 individuals as indicated by Na>Ne and He<Uhe. Gamma irradiation potentially increased both allele number and heterozygosity by approximately 50%. Ten putative-mutant teak seedlings are obtained, these lines should be maintained and propagated as valuable genetic resource for future teak improvement programs

Abstract

Gmelina is a fast growing species that has high sufficient economy value and useful as medicinal plant. Propagation of gmelina by tissue culture has not been widely applied in Indonesia. This study aims to analize the effect of explant types and sterilization methods on the success of gmelina initiation. Treatments used in this study are explant types (apical shoot and leaf) and four sterilization methods (B1-B4) using detergent, tween 80, fungicide, bactericide, NaOCl, and HgCl2. All sterilization methods can produce 6‒19% sterile gmelina shoot culture, but has not succeded producing sterile gmelina leaf culture. Contamination by fungi and bacteria is the main cause of failed gmelina shoot and leaf culture initiation. In general, sterilization methods used in this study has succeeded in eliminating microbes on the explant’s surface, but has not succeeded in eliminating microbes inside the explant.

Abstract

ABSTRACT A lack of seedling maintenance could lead to decreases in the quality of their growth. Stunted root systems could lead to future disruptions in nutrient absorption. In this research, the root system was improved by applying root pruning to improve the growth of new lateral roots. Furthermore, liquid fertilizer was added to further increase plant growth. This study aims to examine the influence of root pruning and bio-stimulants towards the growth of the saplings gmelina (Gmelina arborea Roxb) and canary wood (Nauclea orientalis Linn), both of which had stunted growth in their permanent nursery in Dramaga Bogor, Indonesia. Factorial design with two analysis factors was used in this study. These were root pruning (0% and 30%) and bio-stimulants (0% and 2%). The combination of 0% root pruning and 2% bio-stimulants increased G. arborea growth (diameter, total dry weight, and number of leaves) and N. orientalis growth (height, diameter, and total dry weight). The combination of 30% root pruning and 0% bio-stimulants showed a significant influence on the number of G. arborea leaves. The combination of 30% root pruning and 2% bio-stimulants affected the leaf colour change of G. arborea and increased both of the saplings root growth. In all treatments, G. arborea and N. orientalis saplings had a seedling quality index value in the range of 0.2 – 1.1. Keywords: bio-stimulants, Gmelina arborea, nauclea orientalis, root pruning, seedlings   ABSTRAK Kurangnya kegiatan pemeliharaan dalam persemaian dapat menyebabkan penurunan kualitas bibit bahkan dapat menyebabkan kematian bibit. Salah satu penyebab kematian bibit adalah akar tidak dapat berkembang dengan baik sehingga fungsinya sebagai alat absorpsi unsur hara akan terganggu. Pada penelitian ini, pemangkasan akar dilakukan untuk memperbaiki sistem perakaran dan meningkatkan pertumbuhan akar lateral baru. Oleh sebab itu, penambahan pupuk cair juga dilakukan untuk meningkatkan pertumbuhan tanaman. Penelitian ini bertujuan menguji pengaruh kombinasi pemangkasan akar dan pemberian biostimulan terhadap pertumbuhan bibit gmelina (Gmelina arborea Roxb) dan gempol (Nauclea orientalis Linn) yang keduanya mengalami stagnasi di persemaian permanen Dramaga Bogor. Penelitian dilakukan menggunakan rancangan acak lengkap faktorial, dengan 2 faktor yaitu pemangkasan akar dan pemberian biostimulan. Pemangkasan akar terdiri atas 2 taraf yaitu 0% dan 30%. Pemberian biostimulan terdiri dari 2 taraf yaitu 0% dan 2%. Pemberian biostimulan 2% dapat meningkatkan pertumbuhan G. arborea (diameter, berat kering total, dan jumlah daun) dan meningkatkan pertumbuhan N. orientalis (tinggi, diameter, dan berat kering total). Pemangkasan akar 30% menunjukkan pengaruh yang signifikan terhadap penambahan jumlah daun G. arborea. Sedangkan kombinasi pemangkasan akar dan pemberian biostimulan mempengaruhi perubahan warna daun pada G. arborea dan meningkatkan pertumbuhan akar pada kedua bibit. Pada semua perlakuan, bibit G. arborea dan N. orientalis memiliki nilai indeks kualitas bibit pada kisaran 0,2 – 1,1. Kata kunci: bibit, biostimulan, Gmelina arborea, nauclea orientalis, pemangkasan akar
