Twenty wood species obtained from Irion Joya measuring 5 x 5 x 60 cm were treated by hot and cold soaking using BFCA preservative with 5 and 10 percent of solution concentration. Hot immersion period was kept for 1 hour, 2 hours and 3 hours, with temperature range of 60°C-70°C, followed by cold immersion for 24 hours.The test result of the twenty wood species, after taking both penetration and retention requirements into consideration for wood uses under roof, and in the open air both without soil contact, showed that two wood species among them i.e. nifoek (Eucalyptus deglupta Bl.) and seriega (Eugenia sp.), could not be satisfactorily treated under the experimental conditions. The other eighteen species could be treated by either one, several, or all treating schedules employed in this research. Nevertheless, it is important to note that two of the eighteen species, i.e. sougwa (Palaquium multiflorum) and matoa (Pometia pinna ta Forst.) fulfilled the requirements for wood usage under the roof only without soil contact. The preservation schedule proposed for the eighteen wood species is presented in Table 4.

Industri penggergajian kayu baik skala kecil, menengah dan besar banyak beroperasi di Indonesia. Pada saat mengkonversi dolok menjadi kayu gergajian menghasilkan limbah kayu berupa potongan kecil dan serbuk gergaji. Potongan kecil kayu merupakan bahan berlignoselulosa yang berpotensi untuk menghasilkan etanol. Tulisan ini mempelajari kemungkinan pemanfaatan potongan kecil limbah kayu sengon untuk menghasilkan bioetanol. Pembuatan etanol, dilakukan dengan metode substrat konsentrasi tinggi dengan menghidrolisis substrat konsentrasi tinggi, yaitu 15, 25, dan 35% dan dua konsentrasi enzim (12,5 dan 15 FPU/g substrat). Hasil penelitian menunjukkan, perlakuan konsentrasi substrat 25% dan selulase 15 FPU/g substrat menghasilkan gula pereduksi tertinggi sebesar 248,3 mg/mL; sedangkan konsentrasi substrat 35% menghasilkan kadar etanol tertinggi sebesar 17,7% dengan rendemen sebesar 38,4%. Dapat disimpulkan bahwa metode substrat konsentrasi tinggi dapat menghasilkan kadar etanol yang tinggi pada limbah kayu sengon.

An observation on variousproblems faced by lolflnf companies In practicing timber harunti"6 in their areas was conducted in seven conceaionaires scattered from Sumatra to Irian Jaya in 1989.It ia found that loaf"I companies are (acing many problems in almost all aspects of timber ha"1estingoperations such as In general iuue, planning. roading, utraction, training, and reaearchand development. The m~n source of the problem ia the condition where loggingcompanies do not adapt their technologies to the current technological develop- ment and ifeld eor ?ffinna. For er,,;,._ lnfllt time all loggingcompanies have sticked to the traditional tractor'loggi111 system without considering its suitability to specific local conditions. Alao almost all regulationsabout timber harvestingare.still the same as thpse in early 1910'• and there ia no competent'institution available.,or analyzing various aspects of timber harvating. All of thae ~ause the use ofatatic technology in the middle of many draaticchanges, technology development and working conditionAs the result, it ia noticed in the field that the efficiency of loggingoperations ia low. the rate of loaillf waste ia high,and the environmental diaturbance ia alarming. All of thaee problems need aerious attention both from the govemment and private secto1'8.

PENENTUAN NILAI MANFAAT EKONOMI TAMAN NASIONAL GUNUNG GEDE PANGRANGO SEBAGAI TEMPAT REKREASI Rabayu Supriadi

Indonesian economic growth as reflected by increase of per capita income, improvement of physical infrastructure and facilities as well as socio-economic and political condition have resulted in the increase of recreation demand. The Gede Pangrango Nasional Park is an example of such a forest recreation site with indigenous and exotic flora and fauna, its natural landscape of great beauty and other attractiveness and facilities could stimulate the visitors. As the park is easily reached from the surrounding cities like Jakarta, Bogor, Cianjur, Sukabumi and other cities of Java it seems that demand for recreation in this park is considerably increasing.The objectiveof this study are to get a better insight into the socio-economic aspect of the recreation in the park and to demonstrate the use of internationally accepted method, namely Travel Cost Method, to measure the economic value of the park.The demand equation and demand curve, the annual benefits (consumer's surplus). and the present value of the park have been estimated. The application of the Travel Cost Method (TCM) as a result of this study indicates that the participation rate of the recreation is 2,238 visitor per million inhabitants. The relationship between participation rate (V/P) and directc travel and time cost (TC) can be derived from the demand equation: V/P= -62,5 + 1675240/ TC2 with determinant coefficient, R2= 0.6362. This equation gives the estimated value of the annual benenfits of Rp 1.389 billion or an estimated value of Rp 17,370,- per visit. This is the amount of visitors' willingness to pay on average beyond what they actually pay. This amount gives also a present value of the park of Rp 25,55 billion as the economic value of the park providing recreational opportunity. This figure is based on the assumption that actual visit to the park continues to grow with 6.5 percent annually during the next 30 years and a discount rate of 10 percent, the time value is 50 percent of the hourly income, and are excluded extra cost likefor lodging and the equipment of tents. There will be upward bias due to multi-site visit, and downward bias because of visitors measure rather than day-visit.The expected increase in the number of visitors will place a tremendous pressure on the management of the park. Therefore,improved planning and management activities are needed. This will require an increase of the budget for planning and management to prevent a degradation of the attractiveness of die park. A degradation will mean that the park will lose its high economic value. Further study is recommended to get a more accurate figure of the economic value of the park by inclusion of substitute recreational site, multi-site visit, on-site travel time cost, and all expenses of visitors spent in the estimation of the benefits.

One hundred fifty pieces of wood consisting of 15 species were randomly arranged in form of a raft and floated at Rambut and Puntung Java Islands seashore. The size of the wood specimens is 2,5 cm x 5 cm x 30 cm. The samples were tested against two principal family of marine borers, i.e. teredinids and pholads and evaluated after three months. The results reveal that most of the tested woods were severely attacked by teredinids, except Heritiera littoralis, Heritiera javanica, Diospyros celebica, and Eucalyptus platyphylla, but these species were severely attacked by pholads. The infestation has two distinct types, characterited by its structure and pattern of wood boring
