“…Together with Centrosema pubescens, Pueraria javanica, and Calopogonium mucunoides, P. javanica was able to reduce cumulative sediment by 89.57% at the disposal site and 96.62% at a low wall in a pit when the jute net method was used. This means that this method has proven effective in reducing erosion for post-mining areas (Bargawa et al 2019). Other studies have shown that P. javanica is a type of vegetation that has better growth.…”

Abstract. Zairina A, Mondiana YQ. 2020. The effect of slope level and hydroseeding formula on the growth of Cyperus brevifolius and Pueraria javanica seedlings. Biodiversitas 21: 5008-5012. The aim of this study was to analyze the effect of the slope level on the growth of green kyllinga (Cyperus brevifolius) and puero (Pueraria javanica) seedling in a hydroseeding formula. The hydroseeding mixture consists of plant seeds, compost, soil conditioner, manure, and water. In addition, to all hydroseeding compositions, guar gum and a local microorganism mix were mixed until colloidal mulch was obtained. This study applied factorial design with slope level dan hydroseeding treatment as independent variables, while seed height, number of shoots, and number of leaves were the dependent variables. Data were replicated four times. The hydroseeding formula had a significant effect on all variables, except for the height of C. brevifolius seedlings. There was a significant interaction effect between the slope level and hydroseeding treatment on the germination rate of both species but the effect of this interaction was not significant on plant height and leaf number. The best germination rates were found in boxes with a slope of 100%. This situation was consistent for both species. This indicated that both species had the potential to be used as pioneer plants in post-landslide reclamation with a slope of 100%.

“…The hydroseeding technique could be used for planting species of Leguminosae (Cajanus cajan, Crotalaria pallida, D. triflorum, Indigofera spicata, Sesbania grandiflora), Poaceae (Eleusine indica, Sporobolus indicus, P. conjugatum), and Cyperaceae (Cyperus brevifolius, C. odoratus, Kyllingia monocephala) in Tanah Laut, South Kalimantan, Indonesia [106]. This technique was applied and combined with a jute net for planting C. mucunoides, C. pubescens, and P. javanica, on the steep slope, where it was difficult to replant it, where the soil was easily eroded by rainwater due to the coal exploitation process [107]. The hydroseeding application on post-coal-mining landscapes is presented in Figures 6 and 7.…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

One of the most responsible operations in the cultivation of vegetables includes seeding. Its timing and quality largely determine the quality of sprouts, yield and crop morbidity. The emergence of sprouts can be accelerated and their uniformity can be improved by using hydraulic seeding of germinated seeds. The operation of hydraulic seeders can be divided into main stages: agitation of seeds in a liquid, selection, and dosage of seeds, seeding in the seedbed. The process of seed agitation in a liquid, that is, obtaining a fluidized bed with required seed concentration in the intake chamber of the hydropneumatic precision seeder was considered. The process of seed agitation in the liquid is performed in different ways: bubbling or the use of mechanical stirrers. Each of them requires the use of energy-intensive actuators. A method of seed agitation in a liquid was proposed. It makes it possible to reduce energy consumption by means of agitation, not the entire volume but just the part that is in the zone of seed intake to the seed duct. According to the results of theoretical studies, it has been established that to ensure reliable and accurate seeding, the seed concentration should be in the range of 0.2-0.65 pcs/ml. Under such conditions, the charging process takes place without clogging the seed duct and at an acceptable speed of the seeder. The main factors influencing the formation of a set seed concentration were established: seed diameter, the height of the fluidized bed, flow speed in the intake chamber, the angle between walls of the intake chamber, fluid flow rate. According to the results of theoretical studies of the process of formation of a set seed concentration, limits of existence of the fluidized bed (h 2 = 0.014 m, h 1 = 0.07 m) and height of the seed duct (h H ≈ 0.015-0.02 m) which will ensure reliable and prompt taking of seeds from the intake chamber for their further dosage and seeding. The main provisions of theoretical studies of the agitation process and formation of a set seed concentration were confirmed by experimental studies in a laboratory
