Abstract

Cajeput (Melaleuca cajuputi) is widely used as a post-mining revegetation plant. The addition of organic matter to post-mining land can improve the physical, chemical, and biological conditions of the soil that lead on to increasing growth and endurance of cajeput in polluted land by acid mine drainage. This study aims to analyze the effect of compost mixture media and roasted husk mixture media to endurance and growth of cajeput seedling and also to analyze the effect of acid mine drainage concentration on the endurances of cajeput seedling on various media. This study used a completely randomized design with two factors consisting of acid mine drainage concentration and type of media. The results of this study indicate that the concentration of acid mine drainage has no significant effect on the growth of height, diameter, and number of leaves, also on total wet weight, total dry weight, moisture content, and root length while the type of media used has a significant effect on growth in height, diameter, and the number of leaves. Keywords: acid mine drainage, compost, Melaleuca cajuputi, roasted husk

Abstract

The dormancy of Ketapang kencana seeds can be removed by using pre-treatment in order to breaking dormancy of seeds. The aim of this study was to analyze the effect of pre-treatment for breaking dormancy of seeds, and the seed size on the Ketapang kencana seed germination. Ketapang kencana seeds that have been extracted are classified into 3 sizes, such as: large, medium and small. After that, the seeds were treated with dormancy breaking, such as: (1) control, (2) seeds cutting, (3) seeds sanding, (4) seeds soaking in H2SO4 solution, (5) seeds soaking in hot water (temperature ± 80 oC) for 10 minutes, (6) seeds soaking in water for 12 hours, and (7) seeds soaking in water for 72 hours. The results showed that there were 3 pre-treatments of seeds dormancy breaking that could increase the seed germination, such as cutting the seeds on the endocarp, sanding the seeds on the endocarp, and soaking the seeds in the water for 12 hours. The pre-treatments of seeds dormancy breaking significantly affected the germination index, normal sprout growth (dry weight, height, root length), and the start of sprout growth. Ketapang kencana seed size affected the germination and the dry weight of normal sprouts. The large seeds (0.65–0.82 cm) had the highest germination and dry weight. In general, the pre-treatment of seeds dormancy breaking and the seed size increased the germination of Ketapang kencana seeds. Key words: maximum growth potential, seed germination, seed size, seed viability, seed vigour

Abstract

Potensi Hutan Tropis Indonesia, khususnya di Kalimantan, dari tahun ke tahun terus menyusut. Sistem Tebang Pilih dan Tanam Jalur (TPTJ) diharapkan dapat meningkatkan produktivitas hutan tropis. Penelitian ini bertujuan untuk menganalisis pertumbuhan dan riap diameter tegakan Dipterocarpaceae yang ditanam pada arah tanam Barat-Timur (B-T) dan Utara-Selatan (U-S) pada Sistem TPTJ di areal konsesi PT. Intracawood Manufacturing, Kabupaten Bulungan, Kalimantan Utara, Indonesia. Data pertumbuhan dan riap diameter Dipterocarpaceae diperoleh berdasarkan pengukuran lapangan pada 4 (empat) plot permanen berukuran 100 m x 100 m dengan arah B-T dan U-S. Hasil penelitian menunjukkan bahwa pertumbuhan dan riap diameter rata-rata terbesar pada tegakan berumur lima tahun adalah Shorea parvifolia dengan arah tanam B-T sebesar 8,5 cm dan 1,92 cm/tahun. Sedangkan yang terkecil adalah Dryobalanops lanceolata dengan arah tanam U-S sebesar 4,6 cm dan 0,99 cm/th. Arah jalur tanam tidak mempengaruhi pertambahan diameter. Hal ini disebabkan posisi tegakan pada jalur antara merupakan areal bekas tebangan, yang berada pada sisi kanan dan kiri jalur tanam dengan kerapatan yang rendah dan tinggi tegakan rata-rata yang rendah (17,62 m). Dengan demikian, intensitas cahaya pada arah jalur tanam U-S pada tegakan di jalur antar tidak terhambat. Kata kunci: Arah jalur tanam, intensitas cahaya, riap

Abstract

Kerusakan bibit dalam pengangkutan sering terjadi pada bibit yang menggunakan kontainer (polybag, potray, dan sebagainya), terutama pada saat penyusunan bibit ke dalam alat angkut, selama perjalanan, pada saat bongkar dan pada saat distribusi bibit ke lubang tanam. Salah satu solusi mengatasi masalah kerusakan bibit dalam pengangkutan adalah dengan menggunakan bibit akar telanjang. Penggunaan bibit mahoni yang disemai pada media cocopeat dapat dijadikan bibit akar telanjang dan diharapkan dapat menjawab permasalahan selama pengangkutan dari persemaian ke lokasi penanaman. Tujuan penelitian adalah untuk mengetahui pengaruh umur bibit mahoni (pada media cocopeat di persemaian) dan lama penundaan waktu tanam (bibit akar telanjang) terhadap pertumbuhan tanaman mahoni. Penelitian menggunakan rancangan acak lengkap (RAL) dan rancangan acak lengkap faktorial (RALF) dengan dua faktor yaitu umur bibit dan lama penundaan waktu tanam. Hasil penelitian menunjukkan bahwa pertumbuhan tanaman mahoni yang berasal dari bibit akar telanjang dipengaruhi oleh faktor umur bibit dan interaksi umur bibit dengan lama penundaan waktu tanam. Perlakuan umur bibit yang tua (5,5 bulan) menunjukkan pertumbuhan yang lebih baik dibandingkan perlakuan lainnya. Penundaan waktu tanam hingga 6 hari masih diperbolehkan karena dapat memberikan respon pertumbuhan yang baik. Kata kunci: bibit akar telanjang, penundaan waktu tanam, Swietenia macrophylla, umur bibit

Abstract

Improving the physical quality of kayu kuku seedlings can be done by applying endophytic bacteria and ec-enzymes. The aims of this study were to examine (1) the effect of inoculation of endophytic bacteria on the germination of kuku wood seeds, and (2) the effect of inoculation and application of eco-enzymes on the growth of kuku wood seedlings. The endophytic bacteria were isolated from the shoot of Shorea balangeran plant with the codes SBP 1, SBP 2, and SBP 19. Bacterial application was conducted on seeds and seedlings, while eco-enzyme application was only conducted on kayu kuku seedlings. The results of the research at the seed level showed that inoculation of the endophytic bacteria SBP 19 could accelerate the germination rate of kayu kuku seeds. At the seedling level, inoculation of endophytic bacteria SBP 1, SBP 2, SBP 19 and application of eco-enzymes had no significant effect on height, diameter, number of new leaves, total fresh weight and total dry weight of kayu kuku seedlings. The shoot root ratio of kayu kuku seedlings ranged from 2.66-5.04 and the seedlings quality index ranged from 0.41-0.93, indicating that the seedlings were ready to be transplanted into the field. In general, inoculation of endophytic bacteria had a significant effect on kayu kuku seed germination, but had not been able to increase the growth of kayu kuku seedlings during the 14 weeks of observation. Keywords: Pericopsis mooniana Thw., seed dormancy, seed germination, seedling quality index, shoot root ratio

Abstract

Forest fire is one of the environmental problems that often occurs and is considered important so that it becomes a local and global concern. Forest and land fires are an event that often occurs in Indonesian territory, especially on the island of Kalimantan. Climate is one of the natural factors that can support the occurrence of forest fires, because climatic conditions can affect the dryness of surface fuels. The purpose of this study was to analyze the relationship between hotspots and rainfall on forest fires in Pulang Pisau, Central Kalimantan in the 2017-2021 period. The data used in this study are hotspots using the Terra/Aqua-MODIS (Moderate Resolution Imaging Spectroradiometer) satellite, administrative area data, and rainfall data. The results showed that the highest rainfall was in March of 393 mm/month and the lowest in September was 70 mm/month. High and low rainfall can indicate hotspots which are one of the factors causing forest and land fires. The highest number of hotspots in Pulang Pisau during the 2017-2021 period occurred in 2019 with 3,424 points and the lowest in 2020 with 2 hotspots. This indicates an increase and decrease in rainfall related to the large number of hotspots. Keywords: rainfall, hotspots, fires, Pulang Pisau, Central Kalimantan
