“…The measurement of recovery (yield or conversion efficiency) showed the range of 45~71% (Table 3). Previous research on sengon wood sawing in a flat-sawn pattern (diameter of 24~50 cm) obtained a recovery of 45% with a productivity of 0.66 m 3 /hour (Rachman 1991). The recovery in Wonosobo site showed a smaller variation in value than that in Sleman site.…”

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing and versatile species that has been established in community forests. Many sawmills utilize sengon wood as a raw material which generates wastes in the form of sawdust and slab consisting of a mixture of bark and wood. Those wastes are widely used by communities and home industries as fuel. The objective of this study was to characterize the energy properties of slab wastes from sengon sawmills in Wonosobo dan Sleman Regencies. The results showed that the calorific value and fuelwood value index (FVI) ranges were 4,089 to 4,749 cal/g and 2.71 to 18.74, respectively. The values of density ranged from 0.23 to 0.94 g/cm3. The proximate analysis showed that the values of moisture and ash contents ranged from 13.90 to 20.03% and from 0.30 to 4.59%, respectively, whereas volatile matter and fixed carbon contents ranged from 75.84 to 88.94% and from 10.23 to 20.62%, respectively. In general, the slab samples from Wonosobo gave higher values in fixed carbon content and FVI but smaller values in density, moisture content, volatile matter content, and ash content than those of the samples in Sleman. The bark part showed higher amounts in density, moisture content, fixed carbon content, and ash content but lower in volatile matter content, calorific value, and FVI than the wood part. Based on the wood consumption, sawmill recovery, calorific value, and dry weight biomass value, the potential annual energy from slab wastes in Sleman and Wonosobo reached 1,374 × 1013 cal (equivalent to 1,525,222 L of kerosene) and 1.521 × 1014 cal (equivalent to 16,884,016 L of kerosene), respectively.

“…Faktor lain adalah bilah gergaji, bilah gergaji yang tajam akan meningkatkan jumlah produksi dan mempermudah proses penggergajian. Bandsaw dan bilah gergaji memiliki peran penting dalam proses penggergajian, jika keduanya berkualitas maka kayu yang dihasilkan juga berkualitas dan secara tidak langsung meningkatkan hasil penggergajian kayu sengon (Rachman dan Balfas, 1988).…”

“…Tinggi dan rendahnya volume produksi yang dihasilkan menjadi salah satu indikator keberhasilan penggergajian kayu, efisien atau tidak. Menurut Radam (2011), Rachman dan Balfas (1988), Balfas (1989) keberhasilan suatu produksi dengan membandingkan hasil penggergajian dan bahan baku. Penggergajian dikatakan efisien apabila jumlah bahan baku hampir sama dengan kayu gergajian yang dihasilkan.…”

ABSTRAKEfisiensi pemasaran kayu gergajian sengon berpengaruh besar terhadap keberlanjutan industri penggergajian kayu rakyat. Tujuan dari penelitian ini adalah menganalisis efisiensi pemasaran kayu gergajian sengon pada industri penggergajian kayu rakyat. Penelitian dilakukan dengan wawancara mendalam dan observasi langsung. Pengambilan sampel dilakukan secara sengaja (purposive sampling) terhadap 5 Industri penggergajian kayu yang memproduksi kayu gergajian sengon secara berkelanjutan. Hasil penelitian menunjukan bahwa pemasaran produk papan, balok, kasau dan reng memiliki kecenderungan yang sama terhadap indikator efisiensi pemasaran. Berdasarkan indikator producer’s share dan perhitungan efisiensi pemasaran, pemasaran ke empat produk berjalan efisien akan tetapi berdasarkan indikator margin pemasaran, margin keuntungan dan rasio profit margin, pemasaran berjalan dengan tidak efisien. Hal ini dilihat dari margin pemasaran, margin keuntungan dan rasio profit margin yang tidak merata pada semua produk dan semua saluran. Hasil penelitian ini belum dapat menggambarkan efisiensi pemasaran secara keseluruhan sehingga indikator efisiensi pemasaran lainnya perlu juga dipertimbangkan seperti aspek fungsi-fungsi pemasaran, volume penjualan dan kepuasan konsumen.Kata kunci: efisiensi pemasaran, industri penggergajian, kayu gergajian sengonABSTRACTThe marketing efficiency of sengon sawn wood has a big impact on the sustainability of sawmill industry. The purpose of this research is to analyze the efficiency of marketing of sengon sawn wood in the sawmill. The research was conducted by in-depth interviews and direct observation. Sampling was carried out purposively of 5 sawmills that produce sawn wood in a sustainable manner. The results showed that the marketing of boards, beams, rafters and battens had the same tendency towards marketing efficiency indicators. Based on the producer's share indicator and the calculation of marketing efficiency, the marketing of the four products is running efficiently but based on indicators of marketing margin, profit margin and profit margin ratio, marketing is running inefficiently. This can be seen from the uneven marketing margins, profit margins and profit margin ratios for all products and all channels. The results of this study have not been able to describe the overall marketing efficiency so that other indicators of marketing efficiency also need to be considered such as aspects of marketing functions, sales volume and customer satisfaction. Keywords: marketing efficiency, sawmill industry, sengon sawn wood
