Abstract

[STABILITY IMPROVENT OF STEEP HILL SOIL STRUCTURE BY MEANS OF HYDROSEEDING OF MOSSES AND SOIL CONDITIONERS]. Steep hill is very sensitive to soil erosion and land slide. The objective of this study was to determine the effects of mosses (musci) and soil conditioners applied through hydroseeding technique on the development moss colony and stability of soil structure of steep hill. A randomized complete block design with three replications was used to allocate the treatment combinations of soil conditioners (no soil conditioner, water + manure, and water + manure + latex) and moss species (no moss, Andrea petrophila, and Polytricum commune).  1m x 1m plots were made on steep hill with 65% inclination and each plot was sprayed with 2 L of the soil conditioner and moss mixture (hydroseeding). Observations were made on the moss development and soil physical properties. The results showed that the moss colony increased significantly as applied with soil conditioners.  The highest colony size of moss was found on the application of water + manure + latex (200.85 m-2), followed by water + manure with (156.46 m-2), whereas no soil conditioner produced the lowest (104.91 m-2).  Hydroseeding of moss and soil conditioner had significantly improved the stability of soil structure . Combination of Polytricum commune and water + manure + latex produced the highest improvement in soil structure stability by 93.3 % as compared to the control.

Abstract

Palm oil mill waste is one of the biggest problems in palm oil mill development, hence the need for technology to treat the waste in order to be utilized. This study aims to obtain the composition of organic fertilizer solid waste palm oil factory combined with inorganic fertilizer in the main seedling of oil palm, carried out in the nursery garden of PT. Bio Nusantara Teknologi, Kec. Pondok Kelapa, Central Bengkulu District, from January 2016 to April 2016 with a height of 13 meters above sea level, using Completely Randomized Design (RCD), a factor with 4 replications. Dosage of combination Organic Fertilizer (POP) and Inorganic Fertilizer consisting of 6 levels, namely: O0 = 100% Inorganic (50 g / polybag) + 0% Organic (0 g / polybag), O1 = 80% Inorganic (40 g / polybag) + 20% Organic (100 g / polybag), O2 = 60% Inorganic (30 g / polybag) + 40% Organic (200 g / polybag), O3 = 40% Inorganic (20 g / polybag) + 60% Organic (300 g / polybag), O4 = 20% Inorganic (10 g / polybag) + 80% Organic (400 g / polybag), O5 = 0% Inorganic (0 g / polybag) + 100% Organic (500 g / polybag) ). The results showed that the combination of fertilizer treatment was significantly different from the variability of green leaves, the increase of seedlings 12 weeks after planting (MST), stem diameter 12 MST and leaf-breaking time, and not significantly different on the leaves leaf variable 12 MST.Keywords: palm oil waste,  solid organic fertilizer,  inorganic fertilizer,  palm oil nursery
