Abstract

Sago tree (Metroxylon rumphii) is a potential source of starch and an important contributor of non timber forest products for foodstuff reserve because it has a high carbohydrate content particularly starch. The idea of converting sago starch into dextrin compound is to enhance wider use and increase the economic value of the this commodity. Dextrin has been known for its use as additives in textile industries, pulp/paper industries and pharmaceutical industries.A laboratory trial has been conducted to convert sago into dextrin harnessing the activities of particular enzymes. The aim of this trial was to figure out optimum condition of enzymatic 'sago-processing into satisfactory-quality dextrin, able to comply with the requirement of Indonesian National Standard (INS). The target is to obtain appropriate technology development in sago-derived dextrin.The result revealed that the optimum condition was obtained at substrate concentration of 25 percent with enzyme dosage at 0,9 gram per kg of substrate (dry-weight). In this condition, the dextrin solubility complies with the INS requirement; i.e 25 percent with enzyme dosage at 0,5 gram per kg of substrate (dry- weight).

Abstract

Rotan merupakan salah satu hasil hutan bukan kayu, dan di Indonesia berperan penting sebab memasok 80% kebutuhan bahan baku rotan dunia.  Rotan banyak dimanfaatkan antara lain untuk tali, anyaman, tikar, keranjang, perabot rumah tangga, barang kerajinan, dan produk meubelar.  Pemanfaatan rotan menjadi produk berguna ditentukan diantaranya oleh kerapatan, dan kekuatan (MOR) dan kekakuan (MOE), di mana semakin tinggi nilai ketiga sifat tersebut, maka semakin baik pula kualitas rotan tersebut.  Di Asia Tenggara, termasuk Indonesia, terdapat 2 dari 8 genera rotan yang bernilai ekonomi tinggi, yaitu Calamus dan Daemonorops. Sebagai kaitannya, telah dilakukan pencermatan 25 jenis rotan Indonesia dan kelasifikasinya berdasarkan kerapatan, MOR, dan MOE.  Dua puluh lima jenis tersebut didominasi oleh Calamus spp. dan Daemonorops spp. Penelaahan secara menyeluruh berdasarkan kerapatan, MOR, dan MOE, sebanyak  16%  dari 25 jenis rotan dapat dikelompokkan sebagai kelas I (sangat baik); 36% sebagai kelas II (baik); 32% sebagai kelas III (sedang); dan 16% sebagai kelas IV (rendah).  Penelahan berdasarkan keseluruhan sifat (Kerapatan, MOR, MOE) mengindikasikan 4 jenis rotan yang paling berprospek untuk dimanfaatkan (mulai dari urutan tertinggi) yaitu Korthlsia rigida Bl, Calamus inops Becc.ex Heyne, dan Calamus koordesianus Becc dan Korthalsia echinometra Becc; sedangkan yang paling tidak berprospek adalah Korthalsia zeppelii Burret, Plectocomiopsis geminiflora(Griff) Becc, dan Calamus ornatus Blume dan Daemonorops malanocaetes BL.

Abstract

The EXP-2000 is a multipurpose equipment designed for use in logging operation. especially for loading and skidding of logs. In the first trial conducted in 2001, the productivity of EXP-2000 turned out to be very low i.e. 0.872 m3hm/hour. The investment cost of EXP-2000 was about Rp 67.5 million so the cost of operation was Rp. 28,736.25 per hour. After improvement in the performance has been improved: skidding productivity was increased to 3.293 m3.hm/hour and production cost of was reduced Rp 8. 725.29 per m3.In loading operation, the performance of EXP-2000 has been improved by increasing productivity from 3.293 m3.hm/hour to 34.705 m3/hour and decreasing the cost from Rp. 5,315 per m3 to Rp. 828.03 per m3. It means that the implementation of a new improved EXP-2000 is promising both technically and economically due to higher productivity compared to that of using animal (buffalo) and conventional skyline system previously developed by the Research and Development Center for Forest Product Technology, Bogor - Indonesia.

Abstract

The Forest Product Research and  Development Centre, Bogor, has  constructed  the Lorena,   Singer and the Traditional  fuelwood stoves to measured the  efficiency of each type. The material used for the construction of the stoves are clay, sand, sawdust, red-bricks  and  water.The  efficiency of  each  type  is  measured  by  using  the  stoves  for  cooking  water  to  boiling point in an aluminium pan, where rubber (Hevea brasiliensis) wood is used as fuelwood.The  stoves  efficiency is expressed  as the  ratio  between  the effective  heat the boiled  water absorbs and the potensial heat  produced by  firewoods.The results of the  observations and  calculations  of  the  efficiency of   the  respective types   of   firewood   stoves indicated  that  the  Lorena  stove  has the  highest  efficiency of  24.75%,  followed by the Singer stove with  24.50%, and the traditional  one,  the least  efficient   is 18.64%. Compared  with  the tested  traditional stove, the  Lorena  and  the  Singer stoves  appear  to have high efficiency which consumed 30% less of  fuelwood.
