Ülkemizde artan nüfus sayısına göre odun hammaddesi ihtiyacı da artış göstermektedir. Oluşan bu talep ve artış nedeniyle odun hammaddesinin kesim süreci verim, maliyet, iş güvenliği ve çevresel zararlar açısından önemli bir hal almıştır. Bu çalışmanın amacı, İstanbul Sarıyer bölgesinde yer alan karaçam (Pinus nigra Arnold.) plantasyonlarında Husqvarna 365 motorlu testere ile yapılan kesim, dal alma, ölçme ve boylama çalışmalarında zaman tüketimi, verimlilik ve maliyeti tespit etmektir. Bu amaçla motorlu testere ile yapılan çalışmalarda zaman etütleri yapılmıştır. Bu zaman etütleri sonucunda ortalama 12.62 m boyunda ve 21.41 cm göğüs yüksekliği çapına sahip karaçam meşcerelerinde kesme verimi 2.825 m3/sa olarak bulunmuştur. Zaman etütleri sonucunda bir ağacın ortalama kesim süreci 5.31dakika/sefer olarak belirlenmiştir. Bunun yanında, yapılan çalışmada motorlu testere ile kesim çalışmasının maliyeti 5.53 $/sa ve 1.96 $/m3 olarak belirlenmiştir. Ayrıca, motorlu testerenin yakıt tüketimi 1.85 lt/sa olarak hesaplanmıştır. Çalışmanın sonucunda, motorlu testere verimliliğinin ağaç çapı ve dal alma-boylama ile ilişkili olduğu bulunmuştur.

Time Consumption, Productivity and Cost Analysis of the Motor Manual Tree Felling in the Black Pine (Pinus nigra Arnold.) Plantation Areas

Öz

The need for wood raw materials also increases with the increasing population in our country. Due to this demand and increase, the cutting process of wood raw material has become important in terms of efficiency, cost, occupational safety, and environmental damage. The aim of this study is to determine the time consumption, productivity, and cost of cutting, branching, measuring, and bucking works carried out with a Husqvarna 365 chainsaw in black pine (Pinus nigra Arnold.) plantations located in the Sarıyer region of Istanbul. For this purpose, time studies were carried out with a chainsaw. As a result of these time studies, the productivity of black pine stands with an average height of 13 m and a breast height diameter of 21 cm was found to be 2.825 m3/hour. Additionally, the average cutting process of a tree was found to be a total of 5.31 minutes per session. Furthermore, the cost of cutting with a chainsaw is $5.53 per hour and $1.96 per m3. In addition, the fuel consumption of chainsaw calculated as 1.85 L/hour. As a result, the study found that the efficiency was related to tree diameter and the amount of bucking.
