20.500.12556/RUL-120766 Študija dela na primeru sečnje in izdelave z motorno žago v sestoju belega gabra Work study of motor manual felling and processing: Case study in a hornbeam forest stand V diplomskem delu primerjamo normative gozdnih del s posnetimi normativi sečnje in izračunane stroške sečnje z aktualnimi cenami dela na trgu. Meritve so potekale v GGO Novo mesto, GGE Adlešiči, katastrski občini Belčji vrh, na zasebni gozdni parceli. V raziskavi, ki je obsegala sečnjo 150 dreves v gabrovem sestoju, smo izdelali časovno študijo po kontinuirani metodi in izmerili učinke dela. V času meritev smo posneli 873,15 minute delovnega časa sekača, od tega 54 % produktivnega časa in 46 % neproduktivnega časa. Posneti normativi sečnje so pri prsnem premeru 15 (cm) znašali 12,55 minut/drevo, pri premeru 45 cm pa 25,7 minute/drevo. Posneti normativi so od normativov gozdnih del v povprečju nižji za 41 %. Produktivnost dela je v času meritev znašala 4,09 m3 na produktivno uro dela in 2,23 m3 na delovno uro. Izračunani stroški sečnje so znašali 11,79 €/m3, kar je dvakrat več od primerjane cene sečnje na trgu (6 €/m3). Iz rezultatov je razvidno, da je učinkovitost sečnje odvisna od načina dela in konkretnih razmer na terenu, in da se izračunani stroški dela lahko močno razlikujejo od cene sečnje na trgu. The thesis considers comparison between state standards and measured standards of cutting with chainsaw forest operation. We also compared costs of the work with the actual prices on the market. The measurements on the field took place GGO Novo mesto, GGE Adlešiči, cadastral unit Belčji vrh in a private forest property. The research included 150 threes in hornbeam forest stand. From the obtained data we calculated a proportion of productive vs. non-productive time, which was 54% and 46%. Recorded standards of cutting were at DBH 15 (cm) 12,55 minutes/three and at DBH 45 cm were standards 25,7min/three. Recorded standards are on average for 41 % lower than state standards. Productivity of work in time od measurements was 4,09 m3 on productive hour and 2,23 m3 on working hour. Calculated costs of cutting were 11,79 €/m3, which is two times higher than the actual price on the market (6 €/m3). From the calculations we can recap that the productivity depends on the work method and conditions on the field, while the cost calculation is quite different than the actual market prices. sečnja z motorno žago normativ sečnje gabrov sestoj kalkulacije stroškov stroški felling national standards for felling hornbeam stand cost calculation true false false [A.
