Abstract

Penelitian ini menganalisis aspek finansial proyek Perhutanan Sosial (PS) di Pujon, Jawa Timur. Analisis finansial ini dilakukan untuk mengetahui kelayakan finansial proyek PS, yaitu biaya dan penerimaan proyek berdasarkan harga pasar.Hasil analisis finansial menunjukkan  bahwa dengan tingkat discount rate 16 persen, proyek PS memberikan nilai net present value (NPV) pada  Perum Perhutani sekitar Rp 2.9 juta per hektare (harga tahun 1993).  Surplus finansial ini terutama diperoleh dari hasil penjualan  tanaman pokok  (Agathis lorantifolia). Sedangkan tingkat penerimaan finansial  untuk Perum Perhutani diperkirakan sebesar 27.8 persen.  Karena itu dari pihak Perum Perhutani, proyek PS secara finansial adalah layak untuk dilaksanakan.Pihak petani peserta memperoleh nilai NPV sebesar Rp 7.2  juta per  hektar, jauh  di  atas nilai NPV yang  diterima  oleh pihak Perum Perhutani.  Tetapi dengan tingkat perolehan lahan rata-rata seluas 0.19 ha per keluarga, dan dengan asumsi setiap keluarga terdiri dari 5 orang, petani  hanya  memperoleh  sekitar Rp  280,000 per keluarga  atau Rp 56,000 per kapita. Di samping itu, pendapatan petani per tahun dari proyek PS juga tidak stabil.  Periode tahun ke 4 sampai tahun ke 9 dan tahun ke 21 hingga akhir proyek (tahun ke 35) merupakan masa krisis proyek, dari se-gi pendapatan petani.

Abstract

This experiment is 10 study the effect of steaming duration and chopping sizes of gambier leaves (Uncaria gambir ROXB) on both yield and quality.The steaming duration of the samples were conducted at 30,40, 60 and 75 minutes  and tire chopping sizes of tire sample consisted of  0.5-1  cm,  2-3 cm,  4-6 cm,  and unchopping,  The results were analyzed  using the factorial  design  with two replicates and the difference between means were tested with multiple range Duncan "s test.The results showed than the steaming duration and the chopping sizes had a significant  effect on  the yield,  catechin  consent, insoluble matter and insoluble matter in alcohol.  Combination of 0.5-1 cm     chopping size and 30 minutes steaming duration was the best treatment.  This combination produced  10.34  % yield of gambier ext. act,  75.82%  catechin content,  11.34 % moisture content, 4.75 % ash content,  4.86  % insoluble matter, and 12.03 % insoluble matter in alcohol.

Abstract

The result of the suitability study of two wood species as raw material for veneer and plywood are reported. The wood raw material used rubber wood (Hevea   brasiliensis) and sengon (Paraserianthes    falcataria). The wood used were obtained from  different age classes i.e.10  and 20 years for rubber wood and 10 and 15  years for sengon.  The study  consisted of  log peeling  characteristic, veneer properties and some physical-mechanical properties of plywood (triplex and multiplex).All of the logs from two wood species could be peeled in cold condition, producing 1,5 mm veneer at  a cutting  angle between  89o30-91o30.  The average shrinkage of veneer is 4.51% and the average veneer swelling from oven-dry to air dry is 3.30 %.The bonding strength of plywood from  all wood species conform with the Indonesian standard,  German standard and Japanese standard for type 11 or water resistant. The spesific gravity and mechanical properties of plywood from  the older tree tends higher than  that from  the younger tree.

Abstract

The aim of this experiment is to find  the properties of cassiavera and, breadfruit charcoal and charcoal briquette.The kiln  used was the typical size  of 200 liter oil drum  with specie L  design  incorporating 12 holes of  13 mm in diameter  at different elevations. The kiln also had a short chimney of 30 cm high at the top with 10 cm in diameter. The result showed that charcoal yield were 24.74 % for cassiavera and 23.01 % for breadfruit. Volatile matter was 18.61 %,  fixed carbon was 78.31  %  and calorific value was 7035.03 cal/g  for  cassiavera charcoal and volatile  matter was 14.27 %,  fixed  carbon was 73.10 %  and calorific value was 6320.12  cal/g for  breadfruit charcoalThe moisture  content of charcoal briquette ranges from  8.41 to 5. 92 % ash content from  4. 65 to 5. 03  % ,   volatile matter from 28.87 to 29.48 %, fixed carbon from  65.87 to 66.10  %, density from  O.11  to 0.64  g/cm3,  compressing  strength from 275 to 450 kg/cm2 and the calorific value from  5684. 59 to 6792.58 cal/g.Based on the physical and chemical properties, cassia-vera and breadfruit charcoal briquette can be used as sources of energy.
