Abstract

Community forestry in Babak watershed is one of the efforts to reduce critical land area. The aim of this research was to evaluate the level of community forestry sustainability in both of community forest (HKm) and private forest in Babak watershed. Multidimensional scaling (MDS) was used to analyse the level of community forest sustainability based on the five dimensions of ecology, economy, social, institutional, and technology as well as 29 attributes. Leverage analysis was used to know the sensitive attributes of sustainability, while Monte Carlo analysis and goodness of fit was used to find the accuracy of MDS analysis. The result shows that HKm was in moderate sustainability level (sustainability index 54.08%) and private forest was in less sustainability level (sustainability index 48.53%). Furthermore, the ecology and technology in HKm were classified as less sustainable, while the institution and technology in private forest were considered less sustainable. There were 11 sensitive attributes of HKm and 19 sensitive attributes of private forest. The priorities of attribute improvement in HKm include land recovering (the dimension of ecology) and cooperative development (the dimension of technology). In private forest, the priorities of attribute improvement include leadership capacity building (the institutional dimension) and also the use of silviculture intensive and soil conservation (the dimension of technology).

Abstract

The detailed causal factors of flood have not been established, whether because of the damage of upper watershed, sedimentation resulting in shallow river, forest conversion, the decrease in abundance and structure or high rainfall. The study aimed at finding out the species diversity and structure of the limited production forest (LPF) from the seedling to the tree stage of Arui watershed in Manokwari district. The species diversity was determined based on Shannon-Wiener index, while vegetation structure was determined based on Importance Value Index. There were totally 92 plots of samples drawn using systematic sampling. The results of vegetation analysis showed that there were 174 species of 43 families with the species diversity of 1.5-1.8 that was categorized as moderate. The four dominant species that were always found in seedling, sapling, pole and tree stages included: Pometia pinnata, Teijsmanniodendron bogoriense, Chisocheton ceramicus, and Horsfieldia irya. The conversion of the LPF into non-forestry sector for the purpose of accelerating development must be reviewed by considering hydrology, land, biodiversity, and social and regional aspects in order to prevent and to reduce flood in the coming days.

Abstract

Sustainable development basically lies in the achievement of harmonisation between economic, ecological and social purposes. One form of sustainable development fromthe perspective of ecological dimension is the existence of spatial harmonism. Spatial harmonism means that in every development area have to allocate conservation area that has been identified in the form of forest area or area which serves as a forest (rural forest). Both in forest law and spatial law consider the existence of forets area at least 30 % of the watershed area.The research was conducted at Ngrancah Sub Watershed. Ngrancah Sub watershed is one part of Serang Watershed. According to Forestry minister decree Nr. 328 year 2009, Serang watershed is one of 108 critical watersheds and need to be given priority handling. The aims of this research are : (1) to investigate soil erosion, soil erosion rates, and soil erosion index ;(2) to analyze spatial ecology harmonism based on erosion control to optimize conservation area. Ngrancah Sub Watershed is the catcment area of Sermo Dam. The area of Ngrancah Sub Watershed is almost 2150 hectares. The area is mostly critical showed by the high rate of erosion. The high rate of erosion indicates that Ngrancah Sub Watershed needs to be manage and handled properly to reduce land degradation. Erosion is predicted using RUSLE Method (RUSLE Equation EA = Ri .K.L.S.C.P) and water balance (aridity index) based on its meteorogical function is calculated using Tornthwaite-Mather method. Isohyet methode is used to calculated rainfall while erodibility factor is calculated using Willem Formula (1995). According to Minimum Legible Area (Vink, 1975), research area could be classified into 80 spatial/ecological units. Slope observation and soil conservation practices is done in each spatial/ecological unit as well as soil samples also taken in each spayial/ecological unit. Linear program with QSB+ Software is conducted to analyse the data.The result of the research showed that the erosion rates varies from the lowest rate of 3,83 ton/ha/year to the highest rate of 494,91 ton/ha/year. About 39,98 % of research area is classified as moderate erosion rate area and about 38,39% of the area as high into very high erosion rate area. Based on Erosion Indeks, about 16,22% of the area is classified as the moderate Erosion Indeks and 73,30% of the area as high into very high Erosion Indeks. Spatial Ecology approach for sustainable watershed management by QSB+ program on the effort of erosion controll showed that to achieve spatial ecology harmonism is needed 87,48 % conservation area (area that identified as forest function) from the total area of Ngrancah Sub Watershed. Rural forest development (or agroforestry) involving local community is recommended to meet spatial ecology harmonism considering existing condition of Ngrancah Sub Watershed that only 2 % of forest area in Ngrancah Sub Watershed.

Abstract

Papua is the final fortress of forests in Indonesia. However, floods recently occurred in Jayapura, Paniai, and Manokwari. If causal factors are not identified and early anticipated, the flood will become an annual disaster with more severe impacts. This study aims to identify main factors causing floods using scoring analysis. Data collected include: rainfall, river gradient, water discharge, drainage density, watershed shape, slope and land use. The research results show that the main factor of floods are average daily rainfall in wet month by 86.53 mm day-1 (rather high) with a score of 28, land use dominated by forest and plantation (rather low and medium) with a score of 21, watershed slope dominated by 1-<8% (high) with a score of 5, drainage density of 6.4 (medium) with a score of 3, watershed shape (Rc of 0.30 < Re 0.71) with  somewhat/elongated shape with a score of 2, and river gradient of 0.0062 (low) with a score of 2 respectively. High rainfall causes greater flow of water and runoff. Land use dominated by plantations (21.46%) is thought to be one of the main causes of floods in Masni District. Flood mitigation does not mean that rain should be reduced, but regulates/manages such as stopping the conversion of forest into palm oil plantations, reducing surface runoff by applying soil conservation, making bypass from meandering, dredging sediments, and constructing retaining walls.

Abstract

Changes in land use influence the social and economic characteristics as well as the environmental problems in a sub-watershed. To support the management of a sub-watershed, land use scenarios (biophysics) must be prepared and community involvement level must be improved. So far, the factors used for monitoring and evaluating sub-watershed performance have not been used thoroughly. This research is aimed at finding out the social and economic vulnerabilities tied to the monitoring and evaluation of sub-watershed performance across the sub-districts. This research uses quantitative methods employed to process primary data (biotic: vegetation and settlement, and abiotic: land, climate, geomorphology, and geology), secondary data (community data sourced from the data of BPS; Central Bureau of Statistics) of East Kalimantan Province; in September 2017), and socio-economic data (direct interviews using questionnaires). The primary data were obtained after processing map interpretation and from observation. The results show that high socio-economic vulnerability occurs in areas of high land use vulnerability. Sub-watershed management will be successful if it is done through a "collaborative management" involving all stakeholders. The scenario simulations of this research can be used as reference materials for regional governments in planning, compiling, and implementing the Regional Spatial Plan policies.

Abstract

Flooding has been natural disaster in Indonesia and elsewhere. This research is designed to create scenarios and designs conservation to mitigate flooding disaster.  Data potential ,vulnerability, and duplicated river covering 0.25% of the targeted flooding area were collected and analysed. Five disain of conservation, natural river as control, river normalization, normalization with gabion stone, river straigtening, and straigtening with gabion stone, are proposed, and main targeted responses of these five scenarios are river current velocity. Effectiveness scenarios were analysed using Anova and Tukey test. The results showed that alignment with gabion stone was the most effective scenario for flooding mitigation since this was the most effective in increasing river current velocity. This could prevent riverbank occurrence of avalanche, accelerate river current, overcome flooding, and prevent future flooding. Other scenarios likes dead clicth ended-hallway, canalization, and riparian reclamation are also possible implemented.
