Journal WASIAN contains scientific paper from research result or scientific review in forestry. This journal was issued periodically twice a year (June and December). Journal WASIAN was first issued at 2011 with the name INFO BPK Manado (ISSN 2252-4401), then in 2014 it changed into Journal WASIAN. Wasian is an acronym for Research Information Media, and it’s derived from the name of the local forestry wood endemic to North Sulawesi .

Abstract

Landsliding is one of the natural process that shape the earth’s surface to achieve slope stability and it will be hazard if they threat human life. This study was conducted to identify potential landslide hazard in Manado region using SMORPH method with digital elevation model (DEM) data. ASTER GDEM data provide more detail landslide information than SRTM data because of the higher spatial resolution. Result shows that 716 ha approximately of land have high landslide vulnerability and 1,176 ha approximately of land have medium landslide vulnerability.

Abstract

The aim of this experiment was to identify of survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 year old to support the provision of improved seed. This experiment was arranged in randomized complete block design. The research used 2 factors, i.e. population sources (Carita-Banten, Pendopo-Muara Enim, Lubuk Linggau-Musi Rawas and Solok-West Sumatera) and parent trees (43 parent trees). In this experiment, parent trees factor was nested in the population sources. The result shodwed that survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 years old in Wonogiri were 82.07 %, 2.43 m and 2.85 cm, respectively.
The Utilization of ALOS PALSAR Image to Estimate Natural Forest Biomass: Case Study at Bogani Nani Wartabone National Park (Pemanfaatan Citra ALOS PALSAR dalam Menduga Biomasa Hutan Alam: Studi Kasus di Taman Nasional Bogani Nani Wartabone) Nurlita Indah Wahyuni

Abstract

The development of remote sensing technology makes it possible to utilize its data in many sectors including forestry. Remote sensing image has been used to map land cover and monitor deforestation. This paper presents utilization of ALOS PALSAR image to estimate and map aboveground biomass at natural forest of Bogani Nani Wartabone National Park especially SPTN II Doloduo and SPTN III Maelang. We used modeling method between biomass value from direct measurement and digital number of satellite image. There are two maps which present the distribution of biomass and carbon from ALOS PALSAR image with 50 m spatial resolution. These maps were built based on backscatter polarization of HH and HV bands. The maps indicate most research area dominated with biomass stock 0-5.000 ton/ha.

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.

Abstract

It was estimated that North Sulawesi needs 9,870,093.33 coastal vegetation seeds to rehabilitate the damage of coastal ecosystems which reach 14,805.14 ha, where the largest area 13.884 ha located in other land use. This study aims to provide information of seed germination techniques in Permanent Nursery Kima Atas, Manado. Research was arranged in complete randomized design as factorial with three replications. Ketapang (Terminalia cattapa) will obtain high viability in fluctuation of temperature and humidity, i.e used sand media, without wildlings and placed under 25% shade and rain. Keben (Baringtonia asiatica) through the incision and decay that placed in the open location will obtain viability until 90% within 2 months. Nyamplung (Calophyllum inophyllum) requires shell splitting in order to improve the viability and it can be done by cracking and stripping.

Abstract

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.
