Research Highlights: We found promising success for black walnut (Juglans nigra L.) planted on a legacy surface mine. Our results indicate that direct seeding can be an effective restoration method, and that shelters may not be needed. Background and Objectives: Reforestation in the Appalachian coalfields has primarily relied on the planting of nursery stock late in the dormant season. This study examined the use of direct seeding during the fall, a practice that, if successful, could both reduce costs of planting and open up a new season for reforestation planting. Black walnut is of particular value for wildlife habitats, timber value, and even human nutrition. In addition, it normally occurs in diverse forests with rich soils of the region. Therefore, establishment on previously surface-mined lands may indicate a positive successional trajectory and resilience. Materials and Methods: This study took place in eastern Kentucky, USA, on a site that was surface mined from 1996 to 2000 and subsequently reclaimed as a wildlife habitat. In 2010, the site was decompacted according to the Forestry Reclamation Approach (FRA) by deep ripping with a bulldozer, and in November 2011, a 2 × 2 factorial experiment was initiated to compare the growth of walnut trees planted either by seed or as one-year seedlings, and either with or without tree shelters. Each treatment (four total: Unsheltered Seedling, Sheltered Seedling, Unsheltered Seed, and Sheltered Seed) had three replicate plots of 17 × 9 m, with 50 seeds or seedlings planted per plot. Measurements (survival, height, diameter, and volume) were made in 2012, 2013, and 2016. Effects of planting type and shelter presence, as well as their interaction, were analyzed using linear mixed models. Results: Planting type was significant for all measurements in the first two years (seedlings > seed), but this difference was largely diminished by 2016. There was a significant interaction of the two main effects, such that shelters benefited (or did not affect) those trees planted as seedlings, but hindered those planted from seed.

Augmented Design

Penelitian ini bertujuan untuk mempelajari variabilitas genetik, heritabilitas, dan menyeleksi penampilan genotipe karakter agronomi unggul pada 57 galur sawi untuk digunakan dalam bahan baku konsumsi dan industri. Penelitian ini dilaksanakan di Seed Bank and Nursery, Agrotechno Park Universitas Brawijaya, Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang pada bulan Desember 2018 – April 2019. Metode yang digunakan untuk penelitian ini adalah rancangan acak kelompok diperluas (augmented design). Perlakuan yang diberikan adalah 60 genotipe sawi yang terdiri dari 57 genotipe yang diuji dan 3 varietas sebagai cek. Genotipe yang diuji akan disebar kedalam 5 blok, sedangkan tiga varietas cek akan ditanam pada setiap blok, sehingga terdapat 72 satuan percobaan. Variabel pengamatan karakter agronomi terdiri dari 15 karakter kualitatif dan 24 karakter kuantitatif. Variabilitas yang luas terdapat pada karakter biji per polong, jumlah polong per tanaman, dan berat segar. Heritabilitas tinggi terdapat pada karakter panjang kotiledon, jumlah daun konsumsi, berat segar, umur panen benih, jumlah polong per tanaman, panjang polong, lebar polong, dan jumlah biji per polong. Terdapat galur-galur sawi yang mempunyai karakter unggul untuk bahan baku konsumsi dan industri.

Penelitian ini bertujuan untuk mengkaji keanekaragaman jenis tumbuhan penyusun vegatasi kawasan ekosistem Taman Nasional Gunung Leuser yang mengalami kerusakan akibat pembukaan perkebunan kelapa sawit dengan menggunakan teknologi seed bank. Waktu penelitian berlangsung mulai bulan April sampai September 2018. Pengambilan sampel tanah menggunakan metode jalur. Pada jalur pengamatan diambil cuplikan sampel tanah sesuai dengan kondisi tutupan tajuk dan kerapatan vegetasi yang dibagi menjadi 3 titik yaitu jarang, sedang dan rapat. Kemudian masing-masing titik diambil sampel tanah secara random  sebanyak 3 kali ulangan dengan menggunakan kotak besi berukuran 25 x 25 cm sedalam: (i) 0-5 cm, (ii) 5-10 cm, (iii) 10-15 cm. Tanah kemudian dimasukkan kedalam kantong plastik dengan menggunakan cangkul kemudian diberi label.ampel tanah kemudian disimpan di dalam rumah kaca untuk selanjutnya dilakukan uji perkecambahan. Informasi tentang cadangan biji di dalam tanah penting dalam studi ekologi komunitas karena dapat menggambarkan vegetasi yang ada di atasnya dan mengetahui potensi jenis tanaman lain yang akan tumbuh di habitat tersebut. Dari hasil penelitian ditemukan 13 famili dengan 18 jenis yang tumbuh pada bak-bak penelitian yang terdiri dari 7 jenis pohon dan 11 jenis golongan tumbuhan bawah dengan jumlah seluruhnya adalah 366 spesies. Dari hasil kekayaan jenis kecambah yang tumbuh pada bak pengamatan didapatkan nilai KR, FR dan INP tertinggi terdapat pada jenis Melastoma malabathricum dengan nilai KR (63,115 %), nilai FR (32,692 %) dan INP (95,807 %). Sedangkan untuk nilai terendah terdapat pada jenis Cocculus hirsutus dengan nilai KR (0,273 %), FR (0,962 %) dan INP (1,235 %). Jenis dan jumlah kecambah sangat dipengaruhi oleh ketinggian tempat dan tidak dipengaruhi oleh kedalaman tanah. Jumlah biji terbanyak yang ditemukan di lantai hutan adalah jenis Macaranga gigantea yaitu 28 biji dan jumlah biji terendah yang ditemukan adalah jenis Villebrunea rubescens, yaitu sebanyak 7 biji.

The article addresses the issues of ensuring safe operation of mining equipment in surface mining. It describes the main factors and situations that pose a high risk to human life and health. The most dangerous incidents are shown to be related to limited visibility and blind spots for operators of mining equipment, which can result in collisions and personnel run over. The main technologies and specific solutions used to design collision avoidance systems are described and their general comparison is provided. A particular focus is placed on monitoring the health of employees at their workplace by means of portable personal devices that promptly inform the dispatcher of emergency situations. General technical requirements are formulated for designing of the system to prevent equipment collisions and personnel run over in surface mining operations. The paper emphasizes the importance of introducing a multifunctional safety system in surface mines in order to minimise the possibility of incidents and accidents throughout the entire production cycle.
