Uji Coba Mesin Kabel Layang Expo-2000 Generasi-Ii Dengan Konstruksi Dua Gigi Eksentrik Terpisah Untuk Ekstraksi Kayu

Abstract

Studies of timber extraction was carried out in steep areas by using the prototype Expo-2000 Generation II with engine of 13 HP. Cable line stretching of about 400 m with slope of about 50%. Logs of rasamala of 2-4 m length and diameter ranged of 20-40 cm were extracted to landing around a tower. The machine was placed on the hill located in the middle of two cable stretches.The first cable stretch was used for pulling logs upward and the second cable stretch for pulling downward. The cost for machine investment was about Rp 110 millions with operation costs of Rp 111.975 /hour. Logs extraction productivity is 0.59 m /hour, and the extraction cost was about Rp 189,788 per m . ABSTRAKPenelitian pengeluaran kayu di daerah curam menggunakan teknologi kabel layang prototipe Expo-2000 Generation II bermesin 13 HP telah dilakukan pada bentangan kabel sekitar 400 m dengan kemiringan lapangan sekitar 50%. Dolok kayu rasamala dengan panjang 2-4 m dan diameter antara 20-40 cm dikumpulkan ke dekat tiang ( ). Mesin yang dipakai untuk pengeluaran kayu dipasang di bukit yang berada di tengah dua bentangan kabel. Bentangan pertama untuk menarik ke atas dan bentangan kedua untuk menurunkan ke bawah. Biaya investasi sekitar Rp 110 juta, biaya pemilikan dan pengoperasian alat adalah Rp 111.975/jam, dengan produktivitas pengumpulan kayu sebanyak 0,59 m /jam, maka biaya untuk setiap m adalah sebesar Rp 189.788.Kata kunci : Teknologi kabel layang, pengeluaran kayu, efektif 3 3 1

Performances of Two Prototypes of Log Extraction Techniques Using the Skyline System

“…So, the rope will be damaged sooner or later and would be very dangerous that should be avoided. However, in this system, the carriage is very powerful it could lift up logs even at the bottom of the valley (Endom, 2013(Endom, , 2014). An example of skyline that use rised head system was intended to be tried in natural production forest at PT.…”

Analysis of OSH risk level in forest management activities using remote sensing approach in RPH Takokak, KPH Sukabumi, West Java Province

“…Work accident caused by a slope hazard source is often not the case for minor work accidents. Endom [19] explained that there are often cases of overturned truck accidents due to not being strong uphill and unable to withstand slips due to slippery ground. Cebro et al [31] stated the tendency for slip page to occur is directly proportional to the greater the slope angle, which means the steeper the slope, the tensile load (horizontal load) supported by the soil will be even greater so that the occurrence of slip will increase.…”

“…According to Yuniawati et al [18], stagnant water can also interfere with forest management activities and result in work accidents. Not only that, steep slopes [19], difficult accessibility [20], thick shrubs [21], strong winds [22], and other environmental factors can disturb and even endanger workers. Based on the many sources of hazard from the environment, KPH Sukabumi, particularly RPH Takokak, is one of the forest areas managed by Perum Perhutani, which has forest characteristics with varied sources of hazard.…”
