Abstract

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.

Abstract

The estimation of genetic parameters for stem diameter and plant height of ironwood (Eusideroxylon zwageri T. et B.) was conducted in a progeny trial in Bondowoso, East Java at the age of 5,5 years. The trial was arranged in an incomplete block design, which comprised of 49 families from three provenances (Batanghari, Berau and Kutai Kertanegara) with 4 replications and single tree plot. Families of Batanghari provenance showed the best growth of stem diameter and plant height compared with another provenance. There was significant difference in plant height between families within provenance, whereas stem diameter was not significantly different both of between provenance as well as between families within one provenance. Non-genetic or environmental factors provide considerable influence on plant growth in the progeny test of ironwood until the age of 5.5 years; it was indicated by the residual variance component. Individual heritability for plant height was considered as high (0.37) and stem diameter was considered as moderate (0.26). There was a strong genetic correlation between the stem diameter and plant height (0.95). This information is very important for future genetic improvement of ironwood.

Abstract

Technical rehabilitation planning of BPDAS Tondano on coastal area has reached 10,000 hectares, thus require many seedlings. Nyamplung has potential as rehabilitation plant in coastal at the same time it can support national demand of biofuel. However the nurseries of nyamplung in North Sulawesi are not optimal and need appropriate information of weaning method. This research used completely randomized design with three treatment factors, namely 1) Cutting the leaves consist of two levels ie D1 (pair leaves) and D2 (intact leaf); 2) Cutting intact seeds, consists of two levels i.e B1 (removed seed) and B2 (intact seeds); and 3) Cutting the roots lenght consist of three levels i.e A1 (5 cm), A2 (10 cm) and A3 (15 cm). There were 180 seedlings taken from seed that germinated using cocopeat media. Results of variance analysis showed that the applied treatment only affect the heigth growth. The survival rate is not affected by all treatments or in the other words survival rate reached 100 %. The treatments on leaves and seeds gave significant effect, on the contrary with root treatment. The treatment of intact leaf (D2) and intact seeds (B2) produced the best height growth responses i.e 4.60 cm and 4.63 cm. Keywords: Calophyllum inophyllum, survival rate, weaning technique, height

Abstract

Aketajawe-Lolobata National Park was selected as one of conservation areas in Indonesia due to its important roles to preserve wildlife natural resources and its unique ecosystem. Our research on fauna diversity was designed to identify bird species diversity that inhabited Tayawi’s watershed within the Aketajawe-Lolobata National Park in North Maluku. We explored the area by using transect method; species identification was carried out by visual and vocal encounter. Fifty five bird species were identified and they belong to 25 families. Among them, 17 species were identified as endemic to Maluku and Halmahera islands. Based on our analysis and field observation, these areas had low fauna diversity. We suspected that illegal logging and hunting might have caused a rapid decrease of the bird population in Tayawi’s watershed area. These can be a serious threat if it is not well-anticipated. Therefore, urgent need is required to discontinue the activities of illegal logging and hunting.
