Abstract

Mining activities could have negative impacts on the environment if the tailings produced were not processedproperly. Non-economic tailing is a composite of various minerals (heavy metal) with sandy texture. Environmental impacts that might occur as a result of poor processing of tailings is a disruption of natural ecosystems as indicated by a decline in quality and productivity of the environment as a result of changes in soil morphology and physical properties, chemical, and biological properties. One vegetative technique that could be applied to rehabilitate degraded land is re-vegetation with the application of fertilizer. Compost could improve the physical properties, chemical, and biological properties of soil. Compost was also an agent of bioremediation so that toxic heavy metals elements in growing medium could be eliminated or reduced. The experimental design used in this study was Completely Randomized Design with compost applications consisting of 4 levels of treatment with each level of treatment consisting of 3 replications, each replication consisted of one gmelina seedling. Research showed that the application of compost would significantly affect the growth of gmelina’s height, but not significantly affected the diameter growth. Single-dose effect of 30 g of compost would significantly affect the seedling’s height. The combination of planting and fertilizing glemina using compost could be recommended in an effort to reclaim land of ex-gold mining.

Abstract

The status of Papua New Guinea’s terrestrial mammals is revised according to their geographical distribution, life history characteristics, and current conservation plans and legislation. Considering their uniqueness and threatening factors, their appropriate management is critical to achieve sustainable development in the country. Concerning marsupial species no one has been yet domesticated, there is no organized breeding and their natural productivity is generally lower than ruminants. Their conservation status is related to their size as smaller species are usually more prolific, less conspicuous, and less preferred by hunters. Differences on evolutionary ecology between families are discussed, and recommendations are given for the assessment and further conservation of vulnerable species. Conservation programs must go alongside with rural livelihoods improvement through ecotourism, food security, and marketing of non timber forest products.

Abstract

Debate on the role of local institution in ensuring natural resources sustainability was re-tested in this research. The local institution in question consisted of kewang, church, and sasi darat (rules) being practiced in the management of dusun (forest) in Rumahkay village. This study described the effectiveness of local institution in the sustainable management of dusun under various types of property rights i.e. dusun dati, dusun negeri, dusun pusaka, and dusun parusahaan. Case study method was used in this research. Data were collected through semi-structured interview, participant observation, field observation, dusun stand measurement, and focus group discussion (FGD). The results of this study showed that Rumahkay community had for generations categorized their forest and regulated the rights of ownership and their utilizations through institutional development such as sasi negeri and kewang based upon mata rumah i.e. mata rumah anakele, anauweng, and anarete. While Sasi Gereja complemented kewang institution to be very effective in rules enforcement based on understanding, trust, and obedience. Overall, the strong local institution had been able to enhance the performance of dusun as shown by the vegetation density in dusun dati, dusun negeri, dusun pusaka, and dusun parusahaan.

Abstract

Timber harvesting activities are unquestionably related with high risk of work accidents and health disorders.Such activities were not only burdened the workers with heavy physical workloads due to uneasy workingenvironment, and massive work materials and tools, but also physiopsychologically burdened workers as theywere imposed with both mechanical and acoustic vibrations (noise) produced by the chainsaw. However,  it is acommon practice that most of the workers still ignored the importance of the use of noise reduction devices suchas earmuff or ear plug.  This study was aimed to reveal the factual effects of noise on work concentration of theworkers to provide a scientific basis in supporting efforts in improving workers’ attitude.  The results confirmedthat chainsaw might produce noise during operation.  Noise intensities received by both right and left ears werenot significantly different, indicating that left-handed and normal workers received similar degree of noise inboth side of ears. Further, results also showed that there was a significant difference on the perception and workconcentration of chainsaw operators versus sedentary people to the noise.  These findings proved that hearingability of chainsaw operators had declined due to frequent noise exposure.Keywords: timber harvesting, physio-psychological disorder, noise, chainsaw

Abstract

The concept of hydrological tank model was well described into four compartments (tanks). The first tank (tank A) comprised of one vertical (qA0) and two lateral (qA1 and qA2) water flow components and tank B comprised of one vertical (qB0) and one lateral (qB1) water flow components. Tank C comprised of one vertical (qC0) and one lateral (qC1) water flow components, whereas tank D comprised of one lateral water flow component (qD1). These vertical water flows would also contribute to the depletion of water flow in the related tanks but would replenish tanks in the deeper layers. It was assumed that at all lateral water flow components would finally accumulate in one stream, summing-up of the lateral water flow, much or less, should be equal to the water discharge (Qo) at specified time concerns. Tank A received precipitation (R) and evapo-transpiration (ET) which was its gradient of (R-ET) over time would become the driving force for the changes of water stored in the soil profiles and those water flows leaving the soil layer. Thus tank model could describe th vertical and horizontal water flow within the watershed. The research site was Cisadane Upper Catchment, located at Pasir Buncir Village of Caringin Sub-District within the Regency of Bogor in West Java Province. The elevations ranged 512 –2,235 m above sea level, with a total drainage area of 1,811.5 ha and total length of main stream of 14,340.7 m. The land cover was dominated by forest with a total of 1,044.6 ha (57.67%), upland agriculture with a total of 477.96 ha (26.38%), mixed garden with a total of 92.85 ha(5.13%) and semitechnical irigated rice field with a total of 196.09 ha (10,8%). The soil was classified as hydraquent (96.6%) and distropept (3.4%). Based on the calibration of tank model application in the study area, the resulting coefficient of determination (R2) was 0.72 with model efficiency (NSE)of= 0.75, thus tank model could well illustrate the water flow distribution of Cisadane Upper Catchment. The total water yield was 2.789 mm year-1 from 3,624 mm year-1 of total annual precipitation. The total water yield comprised of a total runoff of 47.39% and 49.23% of sub surface flow and base flow.

Abstract

Understanding the governability of traditional use zone (TUZ) on Marine National Parks is still debated due to various reasons since successful implemented of the governing system could be observed in some areas only. There is a need to assess the contributions and limitations of governance performance sustainability. Using the Cenderawasih Bay National Park as a case, we studied the governance system (GS), system to be governed (SG), and interactive governance (IG) in managing TUZ. Multi-dimension scaling analysis showed that the existing management showed low sustainability (36%) caused by limitation of stakeholders capacity and violations of rules (GS), impact of live fish fishing, coastal ecosystem degradation and low income (SG), adaptive management and feedback from monitoring and evaluation that were not be able to create effective governance (IT). Improvement could be achieved by increasing the integration of these three systems, in which social-ecology system benefit could work under effective governance. This paper also supported the previous finding that household income alternative was the priority for improving management and conservation. It is justified that both direct and indirect benefits to the society or stakeholders could be provided by well-performed governance.

Abstract

Until recently, commercial banks are not interested in providing fund for community-based forest plantations development. Due to that, Ministry of Forestry has been implementing program providing financial access forcommunity forest plantation (HTR) development through revolving fund scheme (PDB-HTR). During 1997 – 2000 Ministry of Forestry had also developed a similar credit scheme called credit for community forest business (KUHR), but its implementation had encountered many problems. This study had compared PDB-HTR scheme and KUHR scheme to get the lessons, so that the implementation of the PDB-HTR will not suffer the same fate with KUHR. The study was carried out using narrative policy analysis approach. Research was conducted in November 2008 to April 2009 in Riau and South Kalimantan Provinces.The results showed that the scheme of PDB-HTR seems has many similarities with the KUHR scheme. From the analysis had been done there are several findings to consider for policy improvements of PDB-HTR namely: the credit scheme and its orientation, on site level organization, application procedure, dissemination/ socialization, and facilitating mechanisms.

Abstract

The accurate estimation of above ground biomass in the natural forests of Papua New Guinea is a key component for the successful implementation of the REDD policy in the country. Biomass densities in a lowland rainforest site located at the northeast of the country were differentiated with Landsat digital images throughout normalized difference vegetation index (NDVI). Submaps of 4,377.69 ha of bands 3 and 4 were georeferenced with affine transformation and a RMSE of 0.529. The calculated NDVI map was sliced to separate its pixel values into 5 classes as they are distributed in the histogram with the assistance of ground truth points. The method is simple, fast and reliable, however swampy palm forest could not be discriminated from dense forests; and different bare land types had to be grouped into a single major class. Therefore other vegetation indexes and/or band ratios are recommended to be tested using images of higher spatial resolution to accurately differentiate more classes.

Abstract

The phenomenon of widespread tree cultivation by local community in some countries during the last three decades has been explained by researchers with a macro perspective. This study is to understand the phenomenon at the micro level and from the native (peasant or farmer) point of view. This study aims to explain the tradition and changes in tree cultivation. Theoris economic system were used as the basis to explain the tradition and changes in tree cultivation in Rambahan village community of the Kuansing District and Ranggang Village community of Tanah Laut District. Case study method was used in this study. The data were collected from informants through individual interviews and focused group discussions. The results of this study show that the cultivation of trees has been practiced and institutionalized in the everyday lives of local people and passed down from generation to generation, as well as a source of socio-economic stability of families. Factors that farmers take into consideration in the selection of tree crops to be cultivated are price, easy to sell, harvesting intensity, knowledge and skills, labor availability (particularly family labor), and capital availability. The results of this study also indicate that some elements of the economic system of Ranggang and Rambahan communities have the characteristics of capitalism adherent, while some other elements have the characteristics of pre-capitalism. In other words, two communities are in a transition between pre-capitalism and capitalism as shown in the practice of tree cultivation.
