Abstract

Black liquor as a waste of (yielded by) pulp factories in Indonesia was estimated to reach more than 2.3 million tonnes/year. The use of this liquid has long been explored for wood adhesive, particularlyfor glue cold setting type. In this research, black liquor was isolated to get lignin isolate by re-precipitation method. The lignin isolate was then added with resorcinol and formaldehyde at molar ratio of Lignin (L): Resorcinol (R): Formaldehyde (F) = 1:0.5:2. Physical. mechanical, and chemical properties of the glue were tested and evaluated using procedures described in Indonesian standard (SN/)and Japanese standard (JAS).Results indicated that the isolate lignin obtained from black liquor contained typical functional groups, namely hydroxyphenolic and  metoxyl. Under FTIR spectrophotometer. the co-polymer lignin resorcinol formaldehyde showed similar infrared wave number  to those of  phenol  resorcinol formaldehyde  resin. The adhesive  yielded from co-polymerization lignin had  a  red-brown colored dilution, typical phenol smell, with 48.95% of  solid content, 3. 71% of free formaldehyde,  and  227.5 minute of gelatinous time. The Lignin resorcinol formaldehyde glue is applicable for laminated  wood  products.

Abstract

Smoke liquid is a liquid obtained from smoke condensation during charcoal firing process. The main content of the smoke liquid is acetic acid, hence, can be used as an alternative latex coagulant. Acid in vinegar can reduce the pH of latex and  cause the latex to coagulate rapidly. This paper determines effectiveness of using  smoke liquid as a latex coagulant and characteristics of the treated latex. The smoke liquid  in this study was derived from pine wood. The smoke liquid solutions consisted of  the crude smoke liquid and the diluted solution in various concentrations of 5, 10, 15 and 20%. The smoke liquid solution was then each poured into a container of  latex. Testing was undergone by observing latex coagulating time, coagulate condition, texture, color, odor and homogenity. The most effective smoke liquid which produced the best latex based on its performances was then taken for further testing of physico-chemical properties which included dry rubber content, plasticity retention index (PRI), initial plasticity (Po), final plasticity (Pa), dirt content, ash content, volatile matter content (Vm), and nitrogen content. Results were then compared with the conventional use of formic acid as a control coagulant. The result showed that the crude and distillate smoke liquid solutions with concentration of  10% produced the best coagulantperformances than the other solutions. Rubber latex treated with the crude smoke liquid produced the best physico-chemical properties and could meet requirements of the Indonesian National Standard (SNI) for Rubber Quality.

Abstract

The paper presents  the result of a study  on the productivity  and cost of haulage on steel and wooden  rails.  The study was  conducted at  4 logging companies in  West  Kalimantan   during  year  1982.  There  were 2  methods of  log haulage observed, namely using locomotive and  manual  pushing.The  logging companies generally  used rail weighing  7 - 10 kg/m  and 5 x 7 cm wooden  rail. The distance between steel and  wooden  rails were  respectively 60  - 70  cm  and  60  cm  or  less.  The  crew  size  varied  from  8 to 12 men  for locomotive haulage consisting  of  12 - 16  lorries,  and  2 - 4 men/lorry for haulage on  wooden rail.  The  result  of  the haulage study  reveals also the productivity figures of respectively  156.9  m3 km/hour  and 2.4 m3 km/hour for the first and the second  methods mentioned   above.                                                                                            Log  transportation   on steel  rail  is safer for the labour compared  with  that on wooden  rail,  and the life of steel  rail is much   longer  than  that,  of  wooden rail.   Although   steel  rail is higher  in the  investment   cost  compared  with  woode'n  rail (Rp  14 - 21  million/km and Rp  2.35 million/km respectively), the average haulage cost per m3' km  is about  one-third  of the  latter  (Rp 80.1/m3 km  and Rp  254.4/m3 km respectively).

Abstract

The wear of wood cutting tools is, generally, the process which makes a usable tool unfit for continued use. The replacement of the worn cutter either by reconditioning or substitution of a new one represents a necessary cost which can be minimized by controlling tool wear. Numerous studies have been conducted through direct observations on the cutting edge using a variety of photographic methods. Such observations are quite complicated and can hardly be introduced to industrial practices. This study is aimed to explore a possibility of determining cutting tool wear indirectly through the work piece observation. It is based on assumption that knife blunting has a direct bearing on the quality of the finished product, i.e., changing the geometry of cutting marks on the wood surface.Boards of two wood species, rasamala and mangium, were seasoned to air-dry condition and planed using new sharp knives at one feed speed of 30 m/min. Observations were carried out sequentially at 5 planing distances, i.e., 10, 20, 40, 80 and 160 m. Cutting marks geometry on the wood surface was distinguished by rubbing the surface gently with a carbon paper. Measurements of cutting marks and the width of cutting peak were undertaken using a digital calliper. Results showed that values of cutting marks and width of cutting peaks markedly increased with increasing planing distances. Blunting process was significantly affected by wood species. Knives used for planing rasamala boards blunted quicker than those used for mangium. These, to some extend, revealed a possible use of cutting marks structure on wood surface for determining the wear of cutting edge.

Abstract

Rubberwood  is  becoming more important in  Indonesia and  hence research for   better treatment of  this  very susceptible wood  species  is badly needed. In general, the impregnation  of  the green wood  results in a limited  penetration.Boiling before preservative treatment by alternating pressure process greatly  improved  the  treatment of rubberwood. A boiling period  for one hour was sufficient to obtain  required penetration  of preservative.

Abstract

A Study of Industrial Plantation Forest model in Padang Lawas, North Sumatera using new concept of HTI (HTI - Mozaic) as HTI - Mix cropping or HTI - agroforestry, as it is not only for wood production but also for agriculture (Horticulture Crop) and grass for cattle was conducted.Optimal solution using Linear Programming approach shows that plant composition ofIndustrial Plantation Forest-Mozaic development in Padang Lawas area are; shorea (10000 ha ), albizia (6914 ha), akasia (9375 ha), palm oil (4757 ha), king grass and brachiaria (2499 ha ). Shorea has a highest shadow price and critical constraint, so the increase in land allocation for shorea will be profitable. Furthermore, post-optimal analysis indicates that land area for shorea is increased double, profit will also increase about Rp 49,361 billions. While for other commodities solutions are relatively stable.

Abstract

Kokon segar memiliki masa simpan yang singkat untuk dapat dimanfaatkan sebagai bahan baku pembuatan benang sutra. Pupa dalam kokon akan tumbuh menjadi ngengat dalam waktu +5 hari. Proses pengeringan tidak hanya akan mematikan pupa, tapi juga menurunkan kadar airnya. Akan tetapi, karena kokon yang telah kering masih mudah menyerap air kembali dari lingkungannya, maka diperlukan alat penyimpanan kokon untuk mempertahankan mutunya. Permasalahan yang dihadapi di lapangan selama ini adalah pengamanan terhadap kokon  kering masih belum dilakukan dengan tepat. Kokon dimasukkan ke dalam karung bawang kemudian ditumpuk di ruangan terbuka yang kondisi suhu dan kelembabannya tidak diatur, sehingga selama penyimpanan kokon yang sudah kering akan menarik air kembali atau diserang jamur maupun serangga. Tujuan penelitian adalah mengamati kualitas filamen dan benang sutra dari kokon hasil uji coba menggunakan alat pengeringan EB-2005D dan penyimpanan EB-2007S yang didesain P3HH Bogor. Hasil penelitian menunjukkan bahwa kualitas filamen maupun benang sutera dari kokon yang dikeringkan dan disimpan pada alat yang didesain P3HH Bogor lebih baik dibandingkan dengan kualitas dari kokon yang disimpan pada ruang yang tidak dikondisikan.
