The Wera Nature Recreation Park (NRP) sustainable nature tourism development requires multi-stakeholder synergy and robust potential resources management, it is necessary to development strategy for an effective conservation area management. The purpose of this study: 1) Knowing the aspects tourism supply of Wera NRP, 2) Knowing the aspects tourism demand of Wera NRP, 3) Analyzing the nature tourism development strategy of NRP Wera, and 4) Knowing the types of nature tourism that can be developed in the NRP Wera. The data analysis method was involves tourism supply-demand analysis and development strategy. Development strategy was located on cell-1 (1,09; 1,33) in Grand Strategy Matrix, meaning that it supports aggressive strategy, i.e. intensive promotion on certain segments especially students and people of age 7 - 35. Based on those results, the development of tourisms are nature panorama, nature phenomenon, wildlife observation, hiking, education and conservation, outbond, religious, and rural tourisms.

Most of non timber forest product (NTFP) utilization taken from natural forests which decrease on productivity annually, including tengkawang producer species which taken from West Kalimantan natural forests. This condition needs an effort to preserve those species from natural population utilization through plantation forest development that require spesific strategy. This study was part of breeding strategy of shorea species producing tengkawang which aimed to species identify and seedling growth evaluation used genetic material from 2 (two) population from West Kalimantan. The research was arranged in 2 (two) steps, i.e.1) species identification used morphology characteristic difference, and 2) seedling growth evaluation (height,diameter,sturdiness). Seedling growth evaluation was arranged in RCBD, with 5 plot (combination of species and source population), contained 25 seedlings and 4 replications (blocks). The result showed that seedlings of shorea species producing tengkawang, i.e. S.stenoptera, S.macrophylla, and S.gysbertsiana can be different from its stipulae morphology characteristic. Growth of 10 months shorea species producing tengkawang seedlings were significantly different on height and sturdiness. Seedlings height were 67,19 – 88,79 cm, seedlings diameter 9,65 – 10,33 mm and sturdiness 7 – 9,21 in range. The best seedling growth was S.stenoptera and S.macrophylla from Gunung Bunga, West Kalimantan.

A progeny trial of nyawai (Ficus variegata Blume) with subline system was established in Mangunan, Bantul, Yogyakarta and designed as a Randomized Completely Block Design. Lombok subline comprised of 17 families and Cilacap-Pangandaran subline comprised of 19 families. This study was aimed to observe growth variation and genetic parameter of these sublines at two years after planting. Varians analysis was performed to find out family effect on survival, height, and diameter traits. Component varians analysis was used to estimate coefficient of genetic variation and heritability. This study showed that survival rate of the trial ranged from 89.01% to 91.42%. Family effect on height and diameter variation was very significant at both sublines. Estimation coefficient of genetic variation for height and diameter traits ranged from 4.41% to 9.04% or categorized as intermediate. Individual heritabilities for height traits ranged from 0.15 to 0.22; diameter ranged from 0.18 to 0.09, while family heritabilities for height and diameter traits ranged from 0.49 to 0.60 and 0.29 to 0.66 respectively.
