Engine Raise Capacity in Terms of Costing Element of Log Skidding Using a Monocable Winch at PT Ratah Timber
Log skidding using a monocable winch is less costly compared to that using a bulldozer (Ruslim, et al., 2011). Study on engine capacity raise on costing elements of log skidding using this monocable winch was aimed at finding out about: (1) Economical aspects, how much the skidding costs involved using this winch. This study was focused on raising the engine capacity from 20-HP to 26-HP. Research method used was a combination of quantitative and qualitative taking into account factors of (1) Dimension (diameters of center, edge and length) of the stems to find out about the stem volume skidded; (2) the time taken in skidding, i.e. finding about the phenomenon of pure and general timeline required; and (3) total and price of equipment, fuel, oil and grease spent.Results of the research indicate that raising the engine capacity in skidding using the 20-HP engine was higher than that of the 26-HP in terms of skidding cost, which was Rp 12.364,83 m-3hm-1 > Rp 10.853,05 m-3hm-1. In other words, raising the engine capacity from 20-HP to 26-Hp managed to reduce the skidding cost on 1 hm distance down to Rp 1.511,78 m-3 Keywords: Skidding, Productivity and Operating cost

Penerapan Reduced Impact Logging Menggunakan Monocable Winch (Pancang Tarik) (Implementing Reduced Impact Logging with Monocable Winch)
Forest harvesting still encounters many problems especially concerning impact to the residual stand and environmental damage. Implementing the reduced impact monocable winch and planning of good skid trails should have a positive impact on work efficiency as well as, reducing damage to the residual stand and soil during felling and skidding activities. Reduced impact logging (RIL) with a monocable winch (Pancang Tarik) system has been tried in several IUPHHKs and it can be concluded that RIL monocable winch system could be applied practically and reduce impact on residual stand and soil damage. Using this technology has many advantages, among others: cost efficiency, locally made, environmental friendly, and high local community participation. Application of the monocable winch system in reduced impact logging is an effort to reduce economical and environment damages when compared to conventional system of ground based skidding with bulldozer system. The aim of this research is to verify the efficiency (operational cost), effectiveness (productivity) and time consumption of monocable winch system. The results indicate that the implementation monocable winch system, has reduced the soil damage as much as 8% ha-1. The skidding cost with monocable system is Rp95.000 m-3. This figure is significantly cheaper if compare with ground base skidding with bulldozer system in which the skidding cost around Rp165.000 m-3.Keywords: mononocable winch, productivity, skidding cost, reduced impact logging, local community</p
